xarmian bc68b84848 fix(cli,mcp): send raw collection slug so an alias can't shadow a real collection (BUG-2630) (#1162)
* fix(cli,mcp): send raw collection slug so an alias can't shadow a real collection (BUG-2630)

The client-side alias map (collections.NormalizeSlug) rewrote seven hardcoded
singulars ("task", "plan", …) to their plurals BEFORE the request. In a
workspace whose collection slug IS one of those singulars, the user's exact
name was rewritten away and their create/list/move landed in a DIFFERENT
collection — silently, with a success message naming the wrong one.

Fix, per lead ruling on the BUG-2630 trail, split by transport:

CLI (real HTTP, may hit a pre-resolver server) — Option 2, one shared helper
cli.WithCollectionAliasFallback: send the RAW slug first (the server's
exact-match-first resolver from BUG-2578 wins, so an exact name is never
shadowed), and retry with the alias ONLY on a collection-not-found error, only
when the alias differs. Keying on collection-not-found is load-bearing: a
request to a collection that exists but fails for another reason is never
retried into the alias (that would recreate the bug). Both the schema fetch and
the create funnel through the helper so typed --field values parse against — and
the item lands in — one collection. On a genuine double-miss the error names the
RAW slug the user typed (collection "widget" not found), not the alias.

MCP remote transport (in-process ServeHTTP against the SAME binary, which always
carries the resolver — no version skew) — drop client-side normalization
entirely and send raw. Also removed the dormant expandPath collection
normalization: no routeSpec uses a {collection}/{target_collection} path
placeholder, so the branch was dead code in the area this fixes.

Search is deliberately out of scope (filed BUG-2659): its collection is a global
c.slug=? FILTER, not a path — a miss returns 200 + zero results, not
collection-not-found, so the retry can't key on it; and handleSearch is
cross-workspace, so the per-workspace resolver has no single workspace to run
against. Cross-workspace copy is excluded too (DR-13 forbids auto-retrying the
copy mutation).

Verified live against a real server: create/list/move into a singular collection
that collides with its plural now land in the named singular; shorthand still
resolves; genuine misses error naming the raw slug. New MCP integration test
reproduces the original shadow (item → PLANS-1) when normalization is restored.

* fix(server,cli): own collection resolution server-side + capability-gate the CLI retry (BUG-2630 Codex r1)

Addresses all three Codex round-1 findings, via the lead's ruling that
dissolves the earlier "retry vs archived-protection" tension by making the
server the sole owner of resolution semantics.

Finding #2 (MCP lost the legacy abbreviations t/i/p/d and phase/phases -> plans,
which the server's ±s resolver did not cover): fold the legacy alias map into
collectionSlugCandidates as a LAST-resort candidate. Exact-match-first and the
archived-claims refusal run for the input and every structural candidate before
the alias is reached, so it never shadows or redirects around a real/archived
collection. Now every client can send the raw slug — including the MCP transport
that can't retry — and lose nothing.

Finding #1 (the client retry re-opened the archived/hidden redirect the server
deliberately refused, because not_found can't be told from absent): add a
collection_resolution capability flag to GET /server/capabilities and gate the
CLI retry on it. Happy path unchanged (raw slug, one request). On
collection-not-found ONLY, the client probes capabilities once (cached): if the
server advertises resolution, its not-found is authoritative — the slug is
absent, archived, or hidden — so the client does NOT retry. Only an older server
that lacks the flag (or 404s the endpoint) triggers the legacy alias retry,
which is non-regressive there since old servers never had the protection. The
probe fails safe toward retry. This makes the follow-up distinct-error-code bug
unnecessary.

Finding #3 (double-fail masked a substantive alias error as "collection not
found"): the helper now surfaces a substantive alias-attempt error verbatim, and
only collapses to the raw-named not-found when the alias ALSO 404s.

Verified live against a resolving server: create/list/move into a singular that
collides with its plural land in the named singular; the abbreviation `i`
resolves to `ideas`; and after archiving `plan`, `create plan` honestly fails
("collection \"plan\" not found") instead of being retried into a live `plans`.
Gates: make lint 0 issues; go test ./... green; make test-pg green.

* fix(cli): fail-closed capability probe + always-retry the schema lookup (BUG-2630 Codex r2)

P1: the capability probe cached ANY failure as "no resolver", so a single
transient blip (timeout/5xx) permanently re-enabled the alias retry and could
bypass the archived/hidden protection on a resolving server. Now the probe
distinguishes a DEFINITIVE verdict (HTTP 200 with the flag, or a clean 404 =
legacy build) from an INDETERMINATE one (transport error / 5xx): only definitive
verdicts are cached, and an indeterminate probe fails CLOSED (trusts the
not-found, no retry) without caching, so the next call re-probes. A genuine old
server still returns a clean 404, so its retry is unaffected. Renamed the
predicate to CollectionNotFoundIsAuthoritative to name what it actually decides.

P2: the create schema lookup hits exact-match-only GetCollection, which does NOT
resolve slugs server-side, so capability-gating it made `create task
--field amount=3` 404 the schema fetch, skip the retry, and send amount as the
string "3". The schema lookup now always retries the alias (nil gate),
restoring typed-field parsing against an aliased collection's schema. Best-effort
as before: a genuine miss still degrades to string fields.

New client test covers the probe: definitive verdicts cache (one probe), and a
transient failure fails closed AND re-probes on the next call (mutation-verified).

* docs(cli): note fail-closed-on-indeterminate as a deliberate safety asymmetry (BUG-2630)

Per lead review: make explicit in CollectionNotFoundIsAuthoritative's doc that
failing closed on an indeterminate capability probe is deliberate — a recoverable
alias-shorthand miss is the safer side of the trade vs a retry doing an
un-undoable wrong-write. Comment-only.

xarmian 052c971785 feat(plugin): consent-gated push monitor + tri-state arm/disarm + envelope (PLAN-2613 S3, TASK-2618) (#1150)
* feat(plugin): consent-gated push monitor + tri-state arm/disarm + envelope (PLAN-2613 S3, TASK-2618)

The plugin layer of the push-consent gate. S2 built the CLI arm/disarm/status
verbs and the arm-state file; S3 makes the monitor existence itself the gate
(D1) and adds the tri-state, the envelope, and the connect ritual.

- Tri-state arm-state file: a session can be explicitly ARMED, explicitly
  DISARMED, or absent. `pad session disarm` now writes a session-scoped OFF
  marker (not a file removal), so a within-session disconnect wins even in an
  auto_arm=true repo — the disconnect verb must not be a lie there. The marker
  dies with the session (same liveness), so across sessions auto_arm remains
  the standing contract. ResolveAnnouncedArmed folds the tri-state over
  auto_arm; the monitor announces its result.

- Gated monitors (monitors.json): the single always-on monitor is replaced by
  two — an `always` auto-arm monitor and an `on-skill-invoke:connect` manual
  monitor — both running scripts/pad-monitor.sh. The wrapper gates on a new
  hidden `pad session should-arm`, dedupes concurrent monitors with a
  liveness-aware per-session lockfile, and carries the reconnect loop so an
  in-session disarm stops the stream on its next reconnect. No consent → the
  monitor exits → nothing listening.

- D5 envelope: a push notification carries the verbatim direction-with-authority
  framing (confirm in-session before anything destructive/irreversible); item-
  change kinds stay a light informational label.

- /pad:connect + /pad:disconnect skills; /pad:status gains a one-line connection
  header from `pad session status`. /pad:connect runs the workspace's
  on-session-start playbooks on the first connect only (D8), tracked by a
  Booted flag carried forward across arm/disarm. plugin 0.2.1 → 0.3.0.

Claude-Session: https://claude.ai/code/session_017jD6t1zjxGSq47SQpZfp1V

* fix(plugin): address Codex R1 on S3 (disarm stops active stream, fail-closed local state)

- HIGH-1: a within-session disarm now stops an ACTIVE stream, not just the
  next reconnect. The monitor re-checks consent every 2s while streaming and
  cancels the connection when it flips to not-armed, then exits (D1's whole-
  stream-behind-consent gate at the top of the loop), so the plugin wrapper
  keeps it dead. Fixes /pad:disconnect being a lie for an idle SSE that might
  never naturally reconnect.
- HIGH-2: a corrupt/unreadable local arm-state file now fails CLOSED
  (LocalArmError -> not armed) instead of falling through to auto_arm, so a
  corrupted disarm marker can't silently re-arm an auto_arm repo. It is not
  reaped (reaping would re-arm on the next read); it is session-keyed and a
  re-arm overwrites it.
- Shell wrapper: an empty (mid-startup) lock pid is treated as live so two
  monitors can't both steal the lock; INT/TERM now exit (a trap otherwise
  resumes the loop and reconnects without a lock).
- Docs: plugin/skills/pad describes the new push-envelope line format;
  connect/status skills distinguish "consent set (armed)" from the server's
  observed connection counts rather than claiming "Connected".

Bounded/safe-direction residuals documented in code: the reap TOCTOU and the
Booted carry-forward race (both fail-closed / benign), and lock pid-reuse
(dedupe only, fails toward not-streaming).

Claude-Session: https://claude.ai/code/session_017jD6t1zjxGSq47SQpZfp1V

* fix(plugin): address Codex R2 on S3 (disarm-watcher timing, semantic corruption fail-closed)

- HIGH-1: the disarm-watcher now starts BEFORE the connection is opened, so a
  disarm during connection/header negotiation cancels the request too (the
  request is built on streamCtx). streamWatchEvents also re-checks consent
  before delivering each notification and stops the stream if it was
  withdrawn, so no push is printed after a disarm even within the poll window.
- HIGH-2: a syntactically-valid but semantically-garbage arm-state file (e.g.
  {} or {"pid":1}) now fails CLOSED via a well-formedness check (StartedAt +
  PID must be present, as our writer always stamps them) before liveness or
  reaping — so it can't be judged owner-dead, reaped, and re-armed through
  auto_arm, nor mistaken for a live headless arm naming init.
- LOW: the cleanup trap uses condition 0 (portable) rather than the EXIT name.
  The disconnect skill note reflects the ~2s active-stream drop.

* fix(plugin): /pad:disconnect always disarms, never gated on a linked workspace (Codex R3)

Consent is session-scoped (keyed by the messaging socket, not the workspace),
so a session that connected in one repo must be able to disconnect from
anywhere — including a directory with no .pad.toml. The old precondition let a
session move to an unlinked directory, "disconnect", and keep receiving pushes.
Verified: `pad session disarm` from an unlinked cwd disarms the socket-keyed
session state; should-arm then reports not-armed back in the original repo.

* fix(cli): enforce the Armed != Disarmed writer invariant in arm-state validation (Codex R4)

armStateWellFormed checked only StartedAt + PID, so a well-stamped file that
violated the writer invariant — both armed and disarmed false (or both true) —
passed validation and, since SessionArmState only branches on Disarmed,
resolved to LocalArmOn and armed. The writer always sets exactly one of the
two; require it, so a neither/both file fails closed (LocalArmError).

xarmian e40df6b31c feat(cli): pad session arm/disarm/status + consent config resolution (PLAN-2613 S2, TASK-2617) (#1149)
* feat(cli): pad session arm/disarm/status + consent config resolution (PLAN-2613 S2, TASK-2617)

The S2 CLI contract S3's plugin skills and S4's web composer build against.
S1 gated push delivery on a server-side armed bit declared at stream
connect; nothing decided WHETHER to arm or sent the declaration. S2 adds
both, defaulting off everywhere.

- ResolveAutoArm (internal/cli/arm_consent.go): pure consent resolver.
  .pad.toml [push] auto_arm is the only per-repo enabler (D4); a per-user
  config auto_arm=false vetoes it (deny-wins); default off. Config
  surfaces: PadToml.Push.AutoArm + config.Config.Push.AutoArm (*bool,
  unset != false), both nil-safe.
- Wire contract: StreamSessionIdentity.Armed sends ?armed=true on the
  event stream — S1's server gate finally has a sender. The monitor
  announces armed = live local arm OR resolved auto_arm, so a repo
  opt-in works end to end with a safe default-off skew.
- Verbs pad session arm/disarm/status: arm/disarm manage a per-session
  local arm-state file; status reports the resolved local/auto decision
  plus the server's own armed/connected counts (new Client.ListSessions),
  degrading gracefully when padd is unreachable.
- Arm-state file (session_arm_state.go): keyed per session by
  CLAUDE_CODE_MESSAGING_SOCKET (cwd fallback for headless, secondary to
  auto_arm). Mandatory liveness — a dead-owner file (socket vanished /
  pid gone) reads as disarmed and is reaped, so a crashed session can
  never arm a future monitor. Local client state only; the server's
  armed bit stays the sole delivery authority.

* fix(cli): address Codex R1 on push-consent (fail-closed config, owner-identity liveness)

- HIGH-1: user config.toml read now fails CLOSED. config.LoadPushConfigAutoArm
  reads the [push] auto_arm value strictly — absent → no opinion, but
  present-but-unparseable → error — and ResolveAutoArmFromDisk refuses to
  auto-arm when it can't confirm the user's veto (was: swallowed by the
  lenient config.Load and treated as no-opinion).
- HIGH-2: arm-state liveness now checks owner IDENTITY, not just presence.
  Socket-keyed files record the socket's mtime and require an exact match,
  so a reused socket path can't revive a stale file. Headless files record
  a Linux /proc start-time token (portable fallback documented) to reject a
  reused pid.
- MED-1: arm-state writes are atomic (temp + rename) and reaping is
  non-destructive (re-checks staleness before removing) — a concurrent
  re-arm is never clobbered.
- MED-2: pad session status applies the .pad.toml URL override, so it
  queries the same server the monitor connects to.
- LOW: malformed arm-state files are now reaped (safe now that writes are
  atomic — a corrupt file can't be a torn in-progress write).

Claude-Session: https://claude.ai/code/session_017jD6t1zjxGSq47SQpZfp1V

* fix(cli): address Codex R2 on push-consent (atomic config write, stronger owner identity)

- HIGH-1: Config.Save() is now atomic (temp + rename), so a monitor
  reconnecting while `pad configure` rewrites config.toml can't read a
  truncated/partial file, miss a [push] auto_arm=false veto, and arm.
- finding 2: socket owner identity now uses inode+device (unix) as the
  primary signal, with mtime as the non-unix fallback — a rebound socket
  or a lingering stale node at the same path gets a new inode and is
  rejected, closing the mtime-collision / reused-node gaps.
- finding 3: headless liveness fails closed when a proc-start token was
  recorded but can't be re-verified (was: fell back to bare pid-liveness,
  which a reused pid passes); zombies (state 'Z') now report not-alive.
- finding 5: `pad session status` applies an explicit --url override too,
  not just the .pad.toml one.
- finding 4 (connect-time TOCTOU): documented as an accepted, bounded
  residual — a disarm racing an in-flight connect is corrected on the next
  reconnect; fully closing it needs S3's server-side disarm-on-open signal.

xarmian 625cab9984 fix: bound item history and stop resolving bodies nobody reads (BUG-2608) (#1147)
* fix: bound item history and stop resolving bodies nobody reads (BUG-2608)

Item history was unbounded on every surface, and summary mode paid for what it
discarded: the endpoint resolved EVERY version by walking the item's whole
reverse-patch chain, and both the CLI and the MCP dispatcher then projected
that away to metadata. An item edited under collab records a version every few
seconds while someone types, so this is routinely hundreds of full-content
reconstructions per history call, for output that shows none of them.

Two independent fixes, because they address different costs.

SUMMARY SKIPS THE WALK. `?summary=true` returns metadata from the raw rows and
never resolves a patch. That is the dominant win: the resolution was pure waste
for every caller except --full. Content and is_diff are cleared TOGETHER — an
empty body still claiming to be a reverse patch would tell a consumer to
resolve something that is not there.

LIMIT BOUNDS THE WINDOW, newest-first. That direction is not a preference: with
reverse patches, reconstructing any version means walking back from current
content, so a newest-end window is the cheap prefix of that walk while an older
one still pays for everything above it. That is also why there is deliberately
no offset — it would advertise a pagination whose later pages cost the same as
no bound at all.

Absent limit stays UNBOUNDED on the endpoint, following the item-list
precedent (maxItemListQueryLimit: "a zero/absent limit is left unbounded — this
only clamps an explicit oversized request"). The defaults live on the CLIENTS,
where a token budget is actually known: `pad item history` defaults to 50 with
--limit to change it, and the MCP catalog action injects 50 (max 300, the same
pair list and backlinks already use). A server that truncates a request nobody
bounded is a silent-truncation trap for third-party API consumers.

The MCP default goes in the CATALOG action rather than either dispatcher, so it
reaches BOTH transports — HTTP reads it off the input, and stdio receives it as
the CLI's new --limit through BuildCLIArgs. ToolSurfaceVersion 0.20 -> 0.21
with a changelog entry, plus instructions.md and README, per the 2304-family
contract discipline. Additive param bump: `limit` already existed, nothing
changed shape, and a v0.20 consumer that sends no limit now gets the newest 50
instead of all — which is the fix, not a break in it.

The restore and single-version-expand paths still resolve the FULL chain, and a
test pins that: bounding their walk would strand exactly the old versions those
paths exist to reach.

Eight mutations, each failing only the leg it targets. Three fixture problems
surfaced that way and are worth naming, because each made a test that could not
fail:
  - force_version in a PATCH body does nothing (`json:"-"` on ItemUpdate), so
    the throttle collapsed six edits into one version; varying the source per
    edit is what actually records them.
  - an 8-byte body is cheaper stored whole than as a patch, so no version was
    ever is_diff=true and the is_diff assertion was inert. The fixture now uses
    a body large enough that the store really stores patches.
  - the cmdhelp test fixture lacked the new --limit flag, so BuildCLIArgs
    silently dropped it. Verified against the REAL cmdhelp tree that the flag
    is present and typed int, so the fixture mirrors the CLI rather than
    flattering it.

* docs: bring CLAUDE.md to v0.21 and name why the two result caps differ (BUG-2608)

Codex round 1, both findings.

CLAUDE.md still described the MCP surface as v0.20 — stale because of my own
bump, in the document every agent working this repo reads first. README and
instructions.md are held to the version by a test; CLAUDE.md is not, which is
exactly why it drifts.

The cap "mismatch" (MCP max 300, endpoint clamp 500) is deliberate layering,
not an oversight — item lists have the identical split (300 in the catalog,
1000 at the endpoint) because the two answer different questions: an agent
token budget is only knowable in the catalog, while the endpoint's clamp is a
server-resource ceiling on what any caller may ask for. But nothing said so
anywhere, so a reader comparing the two numbers had no way to tell design from
accident — which is precisely the report Codex filed. Now stated at the
constant and in CLAUDE.md, including why the versions ceiling is LOWER than the
list one (resolving a version can cost a patch application per row, not just a
row read) and why an absent limit is left unbounded at the endpoint.

* fix+test: honest truncation notice, armed fixtures, and the residual named (BUG-2608)

Codex round 2, both findings, and the second is the more useful one.

CLI TRUNCATION NOTICE was wrong in both directions: it compared the response
length against the requested limit, so an item with exactly N versions was
reported as truncated, and a --limit above the server's ceiling was clamped
there and reported as complete. It now asks for ONE MORE row than it shows and
reports truncation only when that extra row comes back. The one case this still
cannot detect — an ask above the server's own ceiling, where the probe row is
clamped away with everything else — is stated in the code rather than papered
over by hardcoding the server's constant in the CLI.

UNDER-ARMED FIXTURES. The unbounded test seeded 5 versions, so a server quietly
defaulting to 50 would have passed the assertion that denies exactly that; it
now seeds 60. The clamp test seeded 2 and could not observe a clamp at all;
the clamp is now asserted directly against a parseItemVersionsLimit function
extracted for the purpose, over the inputs a URL can really carry (absent, 0,
negative, unparseable, either side of the ceiling).

That extraction replaced my own first attempt, which was worse than no test: it
re-implemented the clamp arithmetic in the test body and asserted the result
against itself. It could not have failed.

THE RESIDUAL, NAMED RATHER THAN IMPLIED. Codex's sharpest point is that the
summary tests cannot detect "resolve everything, then clear the fields" —
verified by mutation: pointing the summary branch at the resolving reader
leaves every handler test green, because the response is byte-identical either
way. So the performance claim does not rest on them. It rests on the handler's
summary branch calling ListItemVersionsPage (one reviewable line) plus a new
store test proving that reader really returns unresolved rows rather than
quietly resolving them — mutation-verified from the other side by making the
resolver a passthrough. The test file says all of this, including that an
end-to-end assertion would need a patch-application counter in the production
path, and why that is not worth it when the cost of being wrong is performance
rather than correctness.

* fix(cli): don't resolve for table output, guard the probe overflow, finish the CLAUDE.md bump (BUG-2608)

Codex round 3, four findings.

--full was treated as "content needed" regardless of output format, but the
table path prints no bodies at any setting — so `pad item history --full`
without --format json made the server walk the entire patch chain to build
content the CLI then dropped. That is the exact waste this bug is about,
reintroduced through the flag meant to opt into it. Content is now resolved
only when it will actually be shown.

The limit+1 probe overflowed at MaxInt: it wrapped negative, the client omitted
the parameter, and a request the user bounded came back unbounded — the
opposite of the ask. Guarded.

The truncation notice's documented blind spot was understated: it is AT the
server ceiling as well as above it, since the probe row is clamped away with
everything else. Wording corrected rather than resolved — the CLI still does
not duplicate the server's constant, because a copied ceiling goes stale
silently and asking for hundreds of versions is already opting out of a bound.

Two more CLAUDE.md sites still called v0.19 current; I fixed only the first on
the previous pass. That document describes the contract in three places and I
updated one, which is its own small lesson about grepping for every instance of
a claim rather than the first.

Live-verified against a real server: --limit 2 truncates and says so, --limit 4
on a 4-version item says nothing (the false positive Codex found), --limit 0
returns everything, --full --format json carries bodies, and the default JSON
shape carries metadata only.

* fix(server): clamp an out-of-range limit instead of treating it as unbounded (BUG-2608)

Codex round 4. `?limit=9223372036854775808` made strconv.Atoi return ErrRange,
which my parser lumped in with 'unparseable' and mapped to 0 — unbounded. So an
absurdly large number defeated the very ceiling the function exists to impose,
which is worse than no clamp at all: the bound looked enforced and was not.

Atoi hands back the saturated value alongside ErrRange, so a range-positive
input is now clamped to the ceiling — it is an oversized ASK, not a malformed
one. Range-negative still falls through to unbounded, matching a plain
negative.

Regression cases cover both overflow directions, and the mutation that
reinstates the old behaviour fails on the exact input.

This is the input-domain lesson again: I enumerated absent, zero, negative and
non-numeric, and stopped at what a person would plausibly type rather than at
what the TYPE admits.

* docs(cli): say in --help that a large --limit is capped server-side (BUG-2608)

Codex round 6, and the third time this ceiling came up — which is the tell that
the disposition was in the wrong place. I had documented it twice in CODE
comments, where the person affected never looks. `--help` says what the flag
does, and it said 'show only the newest N versions (0 = all)', which is false
for an N above the server's cap.

Now stated in both the flag help and the command's long description, including
that the truncation notice cannot detect that case and that --limit 0 is the
way to ask for a complete history.

Deliberately not naming the number: a constant duplicated into help text goes
stale silently, and 'capped server-side' is the part a user needs in order to
act. Behaviour unchanged — this is the artifact catching up with it, which is
the same correction the BUG-2301 sentinel comment and the instructions.md
overclaim both came down to.

* test: seed versions through the store so the fixture stops tripping the rate limiter (BUG-2608)

CI caught this and it is my defect, not a flake. Arming the unbounded test
above the plausible default meant seeding 60 versions, and the fixture did that
with 60 HTTP PATCHes in a burst — which trips the server's rate limiter. It
passed locally and in the Go job and failed under Nix, which is the signature
of a test that was always going to fail intermittently rather than one that
broke.

Seeding now goes through the store. That is not a weakening: versions are
recorded by the store on either path, and the endpoint under test is the READ
side, so seeding underneath the transport costs the assertions nothing while
removing a burst the server is entitled to refuse.

The three things that make this fixture work are now stated where someone would
otherwise undo them by accident — the large body (a small one is stored whole,
so no version is ever is_diff and every diff assertion goes vacuous), the
rotating source (the throttle collapses same-(actor, source) bursts into one
version), and the store-not-HTTP seeding with the rate-limit reason attached.

Re-verified after the change: the fixture still records more than 50 versions
and still produces reverse-patch rows, and the default-cap mutation now uses
the REALISTIC default of 50 rather than the 3 I first tested with — the old
5-version fixture could only have caught an implausibly small cap.

David Barkhausen b9381bf5f1 feat(cli): markdown output on the remaining list surfaces; broaden ANSI stripping (#1080)
Completes #898 and fixes #1076.

Markdown on the seven surfaces left out of #1070, so `--format markdown` is now
honestly global and the flag help collapses to "table, json, markdown":

- `item comments`, `item deps`, `project activity`, `attachment list`,
  `library list`, `role list`, `workspace members`.

Two of those are not tabular, and markdown follows the terminal shape rather
than forcing a table onto them:

- `item comments` keeps the attribution-line-then-body form, and the body is
  emitted VERBATIM. A comment body is authored as markdown; escaping it would
  turn its lists and code fences into literal text. Only the attribution line,
  which we construct, is sanitized.
- `item deps` keeps its two sections as `## Blocks` / `## Blocked by` lists.
  Colour carried the direction in the terminal (yellow out, red in); headings
  carry it here.

New shared spine: `cli.RenderMarkdownTable(w, headers, rows)`. Every cell is
escaped, and ragged rows are padded or truncated to the header width so a short
or long row can't shift the column count and break the table. Wiring a surface
is now naming columns and mapping rows.

#1076 — ANSI stripping covered only SGR (`ESC[…m`), so non-SGR CSI sequences,
OSC-8 hyperlinks, and stray C0 controls survived, both in the table width maths
and in markdown output whose doc comment promised escape-free text. Replaced
`sgrPattern` with `ansiPattern` + `stripANSI` covering OSC, CSI, two-character
Fe escapes, and stray C0/DEL, with TAB/LF/CR deliberately preserved for callers
that normalize them. `displayWidth` now uses it too: a control sequence is
zero-width, so counting it was a column-alignment bug of the same family.

Tests: 12 stripping cases, 4 table-helper cases (including ragged rows), 4
renderer cases for the two non-tabular surfaces, and the routing test extended
to 8 subtests — one per surface, driven through cobra against an httptest
server. Also covers the two gaps named in #1076: `item starred` and the scoped
`item list <collection>` path. Each new guard was proven by mutating the source
and watching it fail, not just by passing.

Gates: go build ./... PASS; go vet PASS; gofmt clean; golangci-lint 0 issues.
Both touched packages show the same 6+2 pre-existing Windows failures as clean
main under an identical sandboxed run.

xarmian c84cf7437c feat(sessions): announce session identity on the event stream (PLAN-2558 S2, TASK-2560) (#1094)
* feat(sessions): announce session identity on the event stream (TASK-2560)

PLAN-2558 S2. S1 gave the presence registry a count of anonymous
uuids; this makes each row nameable, which is what S3 needs for an
honest empty state and S5 needs for a target picker.

A monitor now announces itself when it opens the stream:
X-Pad-Session-Label (the working directory's basename) and
X-Pad-Session-Pid. The server sanitizes both and stores them on the
LiveSession; GET /api/v1/sessions returns them.

TRANSPORT. The task body sketched "the stream connect carries it"
without picking a mechanism and explicitly left the call open. Headers,
because a query param would put the label and pid into every access-log
line (this server logs path= for each request) and any proxy log in
front of it — which is the same "don't let local detail travel further
than it needs to" the privacy line below is about — and a separate
registration POST would need its own correlation to the connection it
describes, plus a matching lifecycle, when the registry entry already
lives and dies with the stream. Headers ride the request that exists
and sit alongside Last-Event-ID, already doing this job on this
endpoint. Cost, written into the code rather than discovered later: a
browser EventSource cannot set headers, so a future web-tab consumer
needs a deliberate query-param fallback or a fetch-based SSE reader.

PRIVACY. The basename crosses, never the full cwd — "/home/dave/Dev/
docapp" additionally hands over a home directory and usually an account
name for no gain — and messaging_socket_path never leaves the machine.
Pinned by a test rather than by the implementation being one line.

WHAT THIS DELIBERATELY DOESN'T DO: read ~/.pad/sessions/. The task
framed S2 as giving `pad session register` its first consumer, and the
monitor cannot honestly be one. Registry entries are written by
whatever process ran that command — a different pid — and the only
matchable fields are pid and cwd, so two agent sessions in one checkout
are indistinguishable and "pick the newest" is a coin flip that would
put a confident wrong name in the S5 picker. Process ancestry settles
it exactly and is platform-specific (this binary ships for macOS and
Windows). The monitor's own cwd basename and pid are never wrong and
answer the question the label exists to answer; correlating a stream to
the agent session that spawned it needs an identifier the harness
passes down, which is worth doing when something needs it and worth not
faking until then.

Also moves S1's STALENESS doc block, which sat above LiveSession.Label
where it read as documenting the name rather than the whole entry.

Tests: sanitizer units (whitespace collapse, control-char stripping,
rune-not-byte truncation), header wiring, the end-to-end labelled
session, the unannounced-client compatibility leg (a pre-S2 monitor
must still register and still stream), a hostile-input leg over the
wire, the client's omit-when-unset behaviour, and the basename promise.

Measured rather than assumed: Go's server answers 400 to a header value
containing a control byte before any handler runs (verified with a raw
socket, since Go's own client refuses to send one and the two refusals
are indistinguishable from a normal client test). So that arm of the
sanitizer is unreachable over HTTP; it stays as defence in depth for
the next caller in, and both the comment and the wire test say so
instead of the test quietly passing because the transport refused the
input.

Mutation-tested four ways, each revert grep-verified: handler ignoring
the parsed identity, monitor sending the full cwd, dropping the
truncation, and the client always setting the headers.

Refs TASK-2560, PLAN-2558

* fix(cli): sanitize the session label client-side per Codex review (round 1)

Codex round 1's only finding, and it is a bigger deal than a missing
label. Unix directory names may contain control bytes — "doc\napp" is a
legal directory — and Go's http.Client REFUSES to send a request whose
header value holds one: Do returns "invalid header field value" and
nothing is transmitted. In the monitor that is indistinguishable from
an unreachable padd, so the retry loop backs off and tries again,
forever, printing nothing by contract. A user who named a directory
that way would simply stop receiving notifications, with no signal
anywhere. The server cannot defend against a request that never
arrives.

Reproduced before fixing, with a real directory and a real client,
rather than reasoned about from the error message.

Sanitizing in NewWatchEventsStreamRequest rather than in
monitorSessionIdentity: the invariant is "this function never builds an
unsendable request", which belongs at the point where a value becomes a
header, not at one caller. The client's cap (256 runes) is deliberately
looser than and independent of the server's (64): the server decides
what a label should look like, the client only has to keep the request
sane, and neither has to track the other to stay correct.

The regression test does the ROUND TRIP instead of inspecting the
header, because the header contents were never the bug — http.Header.Set
stores anything, so an assertion on the value passes against the broken
version too. Only attempting the request tells the two apart.
Mutation-verified: reverting the sanitizer fails the test with exactly
the "invalid header field value" error from the field report.

xarmian da6ce642da feat(push): pad push — user-authored instruction dispatch to agent sessions (IDEA-2544 Phase 1) (#1090)
* feat(push): add pad push <ref> -m vertical (IDEA-2544 Phase 1)

Self-addressed, human-to-harness dispatch over the existing watch-events
bus/stream: CLI -> POST .../items/{itemSlug}/push -> a new KindPush
Notification (carrying the generalized TargetUserID addressed-to field
KindAsk will later share) -> watchNotificationVisible delivers it back
to the pushing user's own connected monitor sessions. Transient,
fire-and-forget by design (no migration, no durable inbox) since
assignment already covers the durable-notification case and this is
meant to be the explicit, no-inference dispatch verb instead.

* docs(plugin): document the push notification contract (IDEA-2544 Phase 1)

Push is the one notification kind that IS an instruction rather than a
passive fact, so it gets its own lead bullet in the plugin skill's
notification-etiquette section (ahead of the read-only/park default,
which it explicitly lifts) and a mention in the monitor's description.
The embed-source skills/pad/SKILL.md has no notification section to
mirror this into (the two files diverge by design) and is left
untouched.

* fix(push): reject over-long push messages instead of unbounded Summary

Comments truncate their notification Summary to a preview (the full
body is still fetchable), but a push message IS the payload — silently
truncating it would corrupt the instruction with nothing to recover it
from. Add maxPushMessageLen (4096, measured post-collapse) and reject
anything over it with a 400 rather than truncating; state the same
bound in `pad push --help` so it's discoverable before a 400, not only
from one.

* fix(push): close the watch-fallthrough leak, disambiguate SKILL.md exceptions

Codex round 1 P1: watchNotificationVisible's push branch only returned
early on a MATCH — a non-target caller fell through to the watch-map
check below it, so anyone holding an unconditional (or predicated)
watch on the item received every push addressed to every OTHER user,
instruction text included. Push is addressed private dispatch, not an
item-level fact watchers have a legitimate claim on (unlike assignment,
which watchers are expected to see per `pad watch --help`) — the branch
now returns unconditionally for KindPush, gating strictly on
TargetUserID and never reaching the watch-map fallback either way.
Pinned explicitly since Phase 4's session targeting is expected to
inherit this same exclusivity.

Also (codex P2): reworded the SKILL.md notification-etiquette bullets —
the new push exception and the pre-existing assignment/ask exception
literally contradicted each other ("the ONE narrow exception" claimed
singularity after push had already claimed exception status). Now
explicitly enumerated as the first and second exceptions to the
never-write rule.

* test(cli): pin that PushItem inherits X-Pad-Agent (BUG-2542 rebase)

Verified, not assumed: PushItem builds its request via c.post ->
c.newRequest like every other mutating client method (CreateWatch
included), so the attribution fix's client.agentName wiring covers it
for free with zero code changes needed on this branch. Adds a live
httptest assertion rather than trusting the code-path read alone —
the same shape as TestClientSendsResolvedAgentHeader, scoped to
PushItem specifically since that's the one method this PR added.

* fix(push): disambiguate workspace in the monitor line and skill contract

Codex round 2 P1: the watch-events stream is user-scoped ACROSS every
workspace a caller has watches in, but formatMonitorLine printed only
ItemRef/Kind/Actor/Summary and dropped the Workspace field the wire
payload already carried — a session linked to workspace A receiving a
notification for workspace B would resolve the wrong item (or 404) with
no signal in the line that anything was off.

Fixed universally, not push-only: grepped plugin/ and skills/ for
anything parsing "PAD ..." lines and found none — the Claude Code
plugin host ingests the stdout line as free-text notification prose,
formatMonitorLine's only real consumer is its own fmt.Println, so there
is no wire-format consumer a workspace prefix could break. The
ambiguity predates push (any watched item across workspaces already had
it); push just makes the consequence sharper because it carries an
instruction rather than a passive fact.

SKILL.md's push bullet now tells the agent to resolve with
`pad --workspace <workspace> item show <ref>` using the slug read off
the notification line, not a bare `pad item show <ref>`.

* fix(push): respect --format json instead of hardcoding plain text

Codex round 2 P2: pushCmd's RunE ignored the global format flag and
always printed "Pushed <ref>", silently discarding --format json.

- server.pushResponse replaces the bare map the handler wrote before —
  a typed {ref, workspace, pushed, message} shape, with workspace
  resolved to the CANONICAL slug via s.getWorkspace (not merely echoed
  from whatever the URL contained), matching the same disambiguation
  need the round-2 P1 fix addressed for the monitor line.
- cli.PushItem now returns (*PushResult, error) instead of discarding
  the response body.
- pushCmd checks formatFlag == "json" and calls cli.PrintJSON, mirroring
  runCreateWatch's existing pattern.

internal/cli/agent_identity_test.go's TestPushItemSendsResolvedAgentHeader
needed a one-line update for PushItem's new two-value return — caught by
`go vet ./...`, not `go build ./...` (which doesn't compile test files);
folding vet into my own pre-flight going forward.

xarmian 212d59e7c6 fix(cli,server): make agent attribution actually happen (BUG-2542) (#1088)
* fix(cli,server): make agent attribution actually happen (BUG-2542)

Agent CLI writes were recorded as the human whose credentials they used.
Three independent defects, each verified by reading the path AND by
probing a live instance — the item deliberately held the mechanism open,
so none of this is inherited.

1. THE HEADER WAS NEVER SENT. actorFromRequest sets actor="agent" on one
   signal: the X-Pad-Agent header. The only code that sets it took the
   value from `agent_name` in .pad.toml and nowhere else — no
   environment detection, no session detection. This repo's .pad.toml
   has only `workspace`, so the header has never been sent from here and
   every agent write has looked human. ResolveAgentName now resolves
   .pad.toml → $PAD_AGENT → detected runtime.

2. ITEM CREATE DISCARDED THE ACTOR. createItemChecked called
   actorFromRequest and kept only the source (`_, src :=`), never
   setting input.CreatedBy, so store.CreateItem fell through to its
   "user" default — even for an agent that DID send the header.
   Comments have always stamped it correctly; item creation silently did
   not, which made the skill's own contract false on its own terms.

3. SINGLE-ITEM PATCH NEVER STAMPED LastModifiedBy. Bulk ops do
   (handlers_items_bulk.go); the single-item path did not, so an item
   edited only by agents read as human-edited.

Only entries VERIFIED against a live session belong in the runtime
detection table, so it has exactly one: Claude Code exports CLAUDECODE=1
to child processes, confirmed by reading a pad subprocess's environment
inside one. Guessing at Cursor/Windsurf/Aider variable names would put
unverified claims in a shipped binary and misattribute silently when
wrong; those set $PAD_AGENT until someone confirms a signature.

WHAT THIS DOES NOT DO, stated in the code and the skill rather than left
for someone to assume: the header is client-supplied and self-declared.
An agent that omits it is indistinguishable from the human it borrows
credentials from, and a human running `! pad ...` inside an agent's
terminal inherits that environment and is attributed to the agent. This
makes the trail HONEST, not VERIFIED — it is not a basis for
machine-verifiable human-approval provenance, which needs a channel the
agent cannot author at all. The incident behind this item is exactly
that distinction: an agent's relay of a human's words was recorded
indistinguishably from the human typing them.

Contract corrected in both skill copies, since the item's first question
was which of contract and behavior was wrong. It was the contract: it
promised automatic agent attribution that only ever applied to
workspaces that had opted in.

Tests, each mutation-tested against its own defect reverted alone:
- TestResolveAgentName — precedence plus the negative that makes it mean
  something: a plain human shell must still resolve to "". Fails 2/5
  reverted.
- TestItemAttribution_AgentVsHuman — agent and human legs for create,
  update and the create-stamp-survives-edit invariant. Fails on the
  create stamp reverted; fails 2/2 on the update stamp reverted.
  The update leg deliberately uses the OTHER writer: insertItemTx seeds
  last_modified_by FROM created_by, so a same-writer edit passes whether
  or not the PATCH stamps anything — the first version of this test did
  exactly that and passed its own counterfactual. Caught only because
  each fix was reverted separately.
- TestItemAttribution_ExplicitBodyValueWins — an explicit body value
  still beats the header.

End-to-end on a live instance through the real CLI, no .pad.toml opt-in:
agent session → created_by/last_modified_by/comment all `agent`; same
binary with CLAUDECODE stripped → all `user`.

* fix(server): artifact import wrote a UUID into created_by (BUG-2542)

Found by Codex while reviewing the attribution fix. handleImportArtifact
set `input.CreatedBy = u.ID`, which is the wrong DOMAIN for the field
rather than merely the wrong value: created_by holds the role — "user"
or "agent" — and consumers compare it against those literals
(CommentThread.svelte, TimelineVersionCard.svelte). An imported item
matched neither and rendered as neither.

It also would have defeated the fix in the parent commit at this path: a
non-empty CreatedBy suppresses the actor stamp, so imports would have
kept a UUID while every other create path started recording the actor.

The line contradicted the comment directly above it, which said Source
was being left blank precisely so createItemChecked could stamp it "like
every other create path". Now both fields are left blank and stamped
together.

The user's identity has its own home — the items.created_by_user_id
column — which no create path currently populates. That is a separate
gap and is not widened into this change.

Claude-Session: https://claude.ai/code/session_01QGbUKZBAZoWdEgiTNWsXag

* fix: close the remaining attribution bypasses Codex found (BUG-2542)

Review found no P1s and three P2 families beyond the artifact-import bug
already fixed in 6fac5dec. Two are closed here; two are deliberately not,
and the reasons matter more than the diff.

CLOSED — paths that asserted "user" and so SUPPRESSED the new stamp,
which made them worse after the parent commit rather than merely stale:

- cmd/pad/notes.go sent CreatedBy/LastModifiedBy = "user" from the
  CLIENT on all four note/decision writes. An explicit body value beats
  the header by design, so every agent note claimed a human wrote it,
  and would have kept claiming it. The client shouldn't assert an
  attribution it cannot know; all four now leave it to the server.
- handlers_item_versions.go hardcoded LastModifiedBy "user" / Source
  "web" on restore, so an agent-driven restore recorded itself as a
  human web edit. Now stamped from the request.

Also closed Codex's nit that the tests injected X-Pad-Agent directly and
never proved the resolver reaches the wire — TestClientSendsResolvedAgentHeader
runs the real client against an httptest server and asserts the header,
with a human-shell leg asserting its ABSENCE. Fails when the client wiring
is reverted. And the Source assertion now pins "web" rather than
merely non-empty.

NOT CLOSED, on purpose:

- Collab flush. An agent PATCH stamps `agent`, then the browser's later
  ?source=collab-snapshot PATCH stamps `user`. Codex reads that as lost
  attribution; I'm not convinced it's wrong — the browser really is the
  writer of that flush, and the agent's edit is already recorded on the
  PATCH that carried it. Deciding whose name belongs on a
  human-flushed doc containing agent edits is a semantics call about
  what last_modified_by MEANS, not a bug I should settle inside a fix
  commit. Filed rather than guessed.
- Move paths don't touch last_modified_by at all. That predates this
  change and is the same question (is a move an edit?), so it goes with
  the above.

Claude-Session: https://claude.ai/code/session_01QGbUKZBAZoWdEgiTNWsXag

* fix(cli): note/decision entries self-declare instead of going authorless

Self-caught regression from the previous commit, found by checking the
thing I changed rather than assuming it behaved like its neighbours.

I removed the CLI's hardcoded CreatedBy: "user" from note and decision
entries on the reasoning that applies to every OTHER write in that file:
an explicit value suppresses the server's stamp, so the client should
stay quiet and let the request context decide. That reasoning does not
reach these two. The entries live INSIDE the item's fields JSON, which
the server stores as an opaque blob and never parses for attribution —
so nothing downstream fills the gap, and blanking it would have written
authorless notes. Worse than the bug I was fixing: "user" was at least
right half the time.

They now carry cli.ActorKind() — the same self-declared signal as the
header, reduced to the user/agent enum the field holds. Its doc says
plainly that this is the ONE place a client should assert attribution,
and why, so the next person doesn't generalise it back the wrong way.

The item-level LastModifiedBy in the same functions stays server-stamped;
that half of the previous commit was right.

TestActorKind covers agent, explicit PAD_AGENT, and human-shell legs.

Claude-Session: https://claude.ai/code/session_01QGbUKZBAZoWdEgiTNWsXag

* fix(server): stamp the actor on non-parent item links (BUG-2542)

Last P2 from the review. Parent links pass the actor to SetParentLink;
every other link type (blocks / blocked-by / relates / implements) goes
through CreateItemLink, which the CLI calls without created_by, so the
store defaulted it to "user" and an agent's `pad item block` recorded a
human. Same one-line shape as the create path, explicit body value still
wins.

TestItemLinkAttribution_AgentVsHuman covers both writers; fails on the
agent leg when the stamp is reverted, control passes either way.

That closes every actor-dropping path the review found except the two
filed as IDEA-2549 (collab flush, move), which are semantics questions
about what last_modified_by means rather than defects — Codex agrees the
deferral holds if the field means content author, and flags that they
become real follow-ups if we decide it means sender-of-write.

Claude-Session: https://claude.ai/code/session_01QGbUKZBAZoWdEgiTNWsXag

* test(server): table-drive every non-parent link type (BUG-2542)

Codex nit: the link regression only covered `blocks`, and "shared routing
makes the other types fine" was doing the work. It cost nothing to stop
assuming, and the table earned itself on the first run — my initial list
included `blocked-by`, which is CLI surface sugar that inverts
source/target into a `blocks` row rather than a stored link type. The API
rejects it with a 400, on BOTH writer legs, which is also how that failure
reads differently from an attribution one.

Now covers blocks / related / implements / supersedes / split_from
against both writers.

One precision fix owed on 06938079's message: it says "THE HEADER WAS
NEVER SENT". Not true in general — a workspace with agent_name in
.pad.toml did send it, which is exactly how I probed the behaviour before
fixing it. Accurate version: the header was absent for anything that had
not opted in, which is every workspace I can see, including this repo's.
The body of that commit says it correctly; the headline overstates.

Claude-Session: https://claude.ai/code/session_01QGbUKZBAZoWdEgiTNWsXag

* style: gofmt notes.go after the attribution edit (BUG-2542)

Removing the hardcoded LastModifiedBy from the two ItemUpdate literals
left the surviving fields aligned to a column that no longer had a
member, so gofmt disagreed and CI's golangci-lint failed the Go job in
42s.

The real fault is upstream of the whitespace: my gates line for #1088
read "go test ./... green · Codex to CLEAN" and lint was simply not in
it. The omission in the report and the failure in CI are the same fact —
I reported a matrix that did not include the axis that broke. `make lint`
runs the pinned suite CI runs and takes seconds; it belongs in every
report I make, alongside test and build.

xarmian ec7fd027fc feat(server,cli): watches, user-scoped event stream, plugin monitor command — PLAN-2469 Phase 1 (TASK-2533) (#1082)
* feat(store): race-free status/assignment mutation signal (TASK-2533)

Adds models.Item.LastMutation (ItemMutationSignal), populated inside the
SAME transaction that already writes status_transitions / assigned_user_id
in UpdateItemWithParentLink and MoveItemWithPreCheck. This is the
foundation for TASK-2533's watch-notification pipeline: a before/after
snapshot taken in the HTTP handler layer would race concurrent writers of
the same item, so the signal is computed where the authoritative diff
already happens, in-transaction.

* feat(store): watches table migration, both drivers (TASK-2533)

watches(id, workspace_id, user_id, item_id, predicate, created_at) per
DOC-2479's subscription-table design: durable, server-side subscriptions
that survive both the plugin-monitor process and a padd restart.
uq_watches_user_item makes `pad watch <ref>` idempotent (re-watching
upserts the predicate). Wires watches into the workspace-purge child-delete
list, mirroring item_stars.

* feat(watchevents): add in-process notification bus (TASK-2533)

New package: a global (not per-workspace) in-process pub/sub bus carrying
watch-worthy Notifications (status-change / assignment / comment; ask
reserved in the enum with no producer yet — see the follow-up server
commit). Bus is an interface specifically so a Redis-backed implementation
can slot in later without touching any caller; only MemoryBus exists today.
Package doc comment states the single-process/multi-instance limitation
explicitly, mirroring internal/events' shape.

* feat(store): watches CRUD (TASK-2533)

models.Watch + Store.CreateWatch (upsert on user+item)/GetWatchByUserItem/
ListWatchesForUser (unscoped by workspace — a watch is personal, and the
event-stream handler needs every watch a caller holds across all their
workspaces)/DeleteWatch.

* feat(server): watch/nudge event stream + CRUD endpoints (TASK-2533)

GET /api/v1/events/stream (DOC-2479): a user-scoped, cross-workspace SSE
stream, filtered server-side to the caller's watches (with optional
--until field=value predicate) plus "addressed to you" — narrowed to
assignment-to-you only for Phase 1, confirmed with the dispatcher: this
codebase has neither a Collection.Kind field nor any user->active-role
binding to ground DOC-2479's "human-gate-shaped collection targets your
active role" half mechanically. watchevents.KindAsk stays in the wire
enum with no producer. `pad session register` is the natural future hook
for a session-carried role identity.

POST/DELETE .../items/{slug}/watch, GET /api/v1/watches (unscoped,
mirrors /auth/tokens' shape for a personal, not workspace, resource).

Producer wiring (TASK-2533 audit) publishes from every live mutation path
that can produce a LastMutation signal or a new comment: handleUpdateItem
(incl. its collab sub-paths and the comment-attached-to-update path, which
bypasses handleCreateComment entirely), handleMoveItem, handleCreateComment,
item creation with an initial assignee, and the bulk-items loop (covers
archive/restore/move/set-priority/tag/untag/assign uniformly via one call
site). Named, not silent, bypasses: import bundle, status_transitions
backfill, workspace restore/purge — none are live human-facing mutations.

Known Phase-1 tradeoff, flagged not fixed: bulk mutations are NOT batched
into one notification the way the existing SSE/webhook bulk path is — a
bulk-assign of N items surfaces N individual notifications. Each is still
correctly scoped by the recipient's own watches/addressed-to-you filter
(a narrower audience than the workspace-wide SSE firehose the existing
batching protects), so this is a noise-discipline tradeoff, not a leak.

* feat(cli): pad watch + pad session register (TASK-2533)

pad watch <ref> [--until field=value] creates/upserts a durable watch;
pad watch list / pad watch remove <ref> are the hygiene companions the
dispatcher asked to be included explicitly rather than silently added.
pad watch --stream --for-session is the plugin-monitor command: one
stdout line per matching event ("PAD TASK-214 -> kind (actor): summary"),
silent on startup with no .pad.toml (hourly retry) or an unreachable padd
(backoff retry) per DOC-2479's noise-discipline contract. The retry/
backoff math and line formatting are pure, unit-tested functions; the
actual sleep loop is not (per the dispatcher's ask).

pad session register writes ~/.pad/sessions/<pid>.json (pid, cwd,
CLAUDE_CODE_MESSAGING_SOCKET when set) -- forward-looking infra for
Phase 3's live-sessions/presence surface; nothing consumes it yet in
Phase 1/2.

* fix(server): comment replies never published a watch notification (TASK-2533)

Codex round 1 finding 2 (verified real, not a false positive):
handleCreateReply is a SEPARATE code path from handleCreateComment — it
calls store.CreateComment directly via POST .../comments/{id}/replies,
not POST .../comments — and was missing the watch-notification hook
entirely. A reply to a comment on a watched item produced zero
notification. Same kind=comment publish as the top-level path, plus a
regression test covering the reply route specifically.

* fix(server): re-check current access before serving/delivering watches (TASK-2533)

Codex round 1 finding 1: ListWatchesForUser filtered only by user_id — a
watch row survives a revoked workspace membership or grant (nothing
deletes it), so GET /api/v1/watches and the event-stream's notification
filter could keep leaking item title/ref, workspace slug, actor, and
summary for access the caller no longer has.

Adds Store.ListWatchesForUser's ItemCollectionID column (needed for the
visibility check) and server.filterWatchesByCurrentAccess, which mirrors
computeSSEVisibility's RBAC resolution (handlers_events.go) — admin
bypass, VisibleCollectionIDs for member/guest full-collection access,
GuestVisibleResources for item-level grants — grouped by workspace since
a caller's watches can span many, unlike a single SSE connection scoped
to one. Fails closed on any lookup error.

Wired into handleListWatches here; the event-stream's loadWatchPredicates
call site picks up the same filter in the next commit, which also
restructures that function's Subscribe/replay sequence and therefore
touches the same lines.

* fix(watchevents): atomic ID assignment + subscribe-and-replay (TASK-2533)

Codex round 1, findings 3 and 4 (same subsystem, fixed together):

Finding 4 — sequence assignment and replay-buffer insertion happened
under SEPARATE locks in MemoryBus.Publish. Two concurrent Publish calls
could append to the ring buffer out of ID order, corrupting since()'s
ordering assumptions (it walks the ring oldest→newest assuming monotonic
IDs). Fixed by unifying seq assignment, buffer append, and the
subscriber-list snapshot under one lock; the (already non-blocking)
fan-out send still happens after releasing it.

Finding 3 — GET /api/v1/events/stream called Subscribe() and, later
(when resuming via Last-Event-ID), EventsSince() as two separate calls.
A Notification published in the window between them landed in BOTH the
replay result and the live channel, double-delivering it. Bus gains
SubscribeAndReplaySince(sinceID), which atomically subscribes and reads
the replay buffer under the SAME lock; the stream handler now uses it
whenever a Last-Event-ID is present (this commit carries that call-site
change, plus the finding-1 loadWatchPredicates filter wiring from the
previous commit — both land in the same lines of this function).

Adds a concurrent-publish ID-ordering test and a subscribe-then-
concurrent-publish no-duplicate test, both run with -race.

* fix(cli): monitor silent-start ordering + sync_required handling (TASK-2533)

Codex round 1, findings 5 and 6:

Finding 5 (P1) — runWatchMonitor called getClient() once, before the
loop and before the .pad.toml check. getClient() -> getConfiguredConfig()
os.Exit(1)s when unconfigured with no TTY, or launches an INTERACTIVE
configuration wizard when one is attached — either way a direct violation
of DOC-2479's silent-start contract, which requires "not ready yet" to be
a silent retry, never a crash or a prompt. Adds monitorClient(), which
builds the client the same way but returns a plain error instead of
exiting or prompting; client construction now happens INSIDE the loop,
after the .pad.toml gate, on every iteration, and its failure folds into
the existing padd-unreachable backoff path.

Finding 6 (P2) — streamWatchEvents ignored "sync_required" (the server's
signal that the requested Last-Event-ID was evicted from its replay
buffer), so a stale cursor got resent on every reconnect forever. Now
clears the cursor on sync_required so the next reconnect is a fresh,
non-resuming subscription instead.

Both covered by tests that assert the goroutine returns promptly on
context cancellation (proving no os.Exit / no blocking prompt was hit,
since the test process itself is still running to observe the return)
and that streamWatchEvents clears/re-tracks the cursor correctly around
sync_required.

* fix(server): uniform current-access gate for watch AND addressed-to-you delivery (TASK-2533)

Codex round 2, findings 1 and 2 — same subsystem (watch/nudge delivery
access control), fixed together; finding 2 explicitly falsifies finding
1's fix's own admin-bypass argument, so this replaces that reasoning
rather than patching around it.

Finding 1 (confirmed real): VisibleCollectionIDs / GuestVisibleCollectionIDs
deliberately over-widen for navigation — a collection ID is included if the
caller has an item grant on ANY item inside it, explicitly leaving
item-level narrowing to the caller (their own doc comments say so).
computeWatchAccessVisibility used that over-wide set directly as the
"fully visible" gate, so a guest granted item A was treated as having full
access to A's WHOLE collection, including an ungranted sibling item B.
Fixed by building the "genuinely full access" set from
GuestVisibleResources' fullCollectionIDs (populated only from direct
collection_grants, never widened by an item grant) + GetMemberCollectionAccess
/ ListSystemCollectionIDs for an actual member — exactly computeSSEVisibility's
own fullCollSet construction, not an approximation of it.

Finding 2 (confirmed real): the addressed-to-you (KindAssignment) branch in
watchNotificationVisible returned true unconditionally, with NO access
check. validateAssignmentScope (internal/store/items.go) only checks
WORKSPACE membership, never collection access, so an item can be assigned
to a "specific"-access member whose granted collections don't include it
at all — an ordinary assignment, no revocation timing required. Fixed by
gating EVERY notification kind — watch-matched and addressed-to-you alike —
through the SAME watchAccessVisibility check before either branch runs.
watchevents.Notification gains CollectionID so the check has what it needs
without a second lookup; the stream handler resolves it lazily per
workspace via a small connection-scoped cache (workspaces aren't known in
advance for addressed-to-you the way watch workspaces are), cleared on the
same reval tick that reloads the watches map.

This also required replacing computeWatchAccessVisibility's admin-bypass
argument, not just its code: "every call site filters the caller's OWN
watches" stopped being a sufficient justification once addressed-to-you
(which is fundamentally about *this* caller's own assignment activity
across every workspace) shares the same gate — a bearer-borne admin token
unconditionally trusted for that is exactly BUG-1616's blast radius. Now
mirrors computeSSEVisibility's cookie-vs-bearer distinction exactly.

Tests: guest-with-item-grant no longer sees a sibling item's watch or
stream notification (filter-level and HTTP/SSE-level); an assignment
outside a restricted member's granted collections is denied at both
levels; addressed-to-you is proven still gated (denied with no access,
visible once granted) as a pure unit test.

* fix(store): always re-read existing under lock, not just for precheck/patch updates (TASK-2533)

Codex round 2 finding 4, verified real: updateItemWithParentLinkOnce's
`existing` snapshot was only refreshed under the write lock when precheck
!= nil, ExpectedUpdatedAt != "", or FieldsPatch != nil — any update
touching none of those (e.g. a plain title-only PATCH) kept the STALE
pre-tx `existing` for the rest of the function, including the
LastMutation assignment-delta comparison added in TASK-2533's first
round. A concurrent OTHER transaction's assignment change landing between
this transaction's pre-tx read and its lock acquisition would get
misattributed to THIS transaction: a title-only update could report a
spurious, wrongly-attributed AssignmentChanged for a transition it never
made, duplicating the one the other transaction already reported
correctly (or missing a real one, depending on interleaving).

The status-transition capture already defended against exactly this with
its own separate conditional re-read; the assignment-delta capture added
later did not replicate that guard. Fixed by making the re-read
unconditional — once, right after the locks are held, before any SET-
clause building or the UPDATE itself — so every existing.* comparison in
this function is race-free by construction, not by each caller
remembering to guard itself. Also removes the now-redundant duplicate
re-read the status code had of its own.

Reproduces the exact race deterministically using UpdateItemWithPreCheck's
precheck hook as a synchronization point (TX2's assignment change blocks
mid-transaction while TX1's title-only update races its own pre-tx read
against it) — the new test fails reliably against the pre-fix code and
passes reliably (including under -race, and in Postgres mode) against
the fix.

* fix(watchevents): send under the same lock Unsubscribe/Close use (TASK-2533)

Codex round 2 finding 3, confirmed real and high-severity: Publish
snapshotted subscriber channels under the lock, released it, and only
then sent to them. A concurrent Unsubscribe or Close could close one of
those channels in the window between the snapshot and the send — a send
on a closed channel PANICS in Go, which crashes the whole padd process,
not just one subscriber's connection. The reasoning for releasing the
lock before sending ("a slow subscriber would stall everyone else") didn't
hold up: the send is already non-blocking (select/default — a full
channel is dropped-and-logged, never awaited), so holding the lock
through it costs nothing and closes the window structurally.

Adds a hammer test (many iterations of concurrent Publish / Subscribe /
Unsubscribe / Close, short-lived churned channels, recover()-wrapped so a
regression fails cleanly instead of crashing the whole `go test` run) that
reproduces "send on closed channel" dozens of times per run against the
pre-fix code (plus an independent -race detection) and passes cleanly,
repeatedly, against the fix.

* fix(server): re-fetch the user, not just the vis map, on each reval tick (TASK-2533)

Codex round 3, confirmed real: watchVisCache captured *models.User ONCE
at connect time (newWatchVisCache) and never re-fetched it; reset()
cleared only the per-workspace visibility map. computeSSEVisibility's own
doc comment explains why it re-fetches the user fresh on every call —
"so mid-stream role changes (admin demotion, user.disabled flips) take
effect on the next tick" — and the round-2 commit claimed to mirror that
"exactly," but only carried over the collection/bearer logic, not the
re-fetch itself. Net effect: a demoted or disabled admin kept fullAccess
on an open stream (both watch-matched and addressed-to-you delivery,
since both go through this same cache) until reconnect.

Adds watchVisCache.refreshUser, called by both the constructor and
reset() so the cadence matches computeSSEVisibility's actual cadence in
handlers_events.go (that function is invoked once at connect and again
only on each membershipCheck tick — never per event — so "per cache
reset" here is the same cadence, not a narrower one). Deliberately fails
CLOSED (not open-to-stale like computeSSEVisibility's own transient-error
fallback) on a fetch error, a deleted user, or a disabled user — a nudge
stream's wrong failure mode is delivering a fact to someone who
shouldn't see it, not a dropped UI update, so this trades
computeSSEVisibility's availability-leaning fallback for a stricter one
and says so in the comment rather than repeating the "mirrors exactly"
claim the fix falsified.

Tests: a unit-level pair (mirroring handlers_events_revalidation_test.go's
existing admin-demotion/disable coverage of the analogous SSE gap
exactly) proves an admin loses fullAccess after a demotion + reset(),
and a disabled user is denied outright; an HTTP/SSE-level test proves a
live stream stops delivering entirely once its connected user is
disabled and a reval tick passes. All three reproduce the bug reliably
against the pre-fix code and pass cleanly against the fix.

The HTTP-level test deliberately runs serially (not t.Parallel()): it
mutates the package-level watchListRevalInterval var, which every other
parallel watch-stream test in this package also reads via its own
ticker — writing to it from a t.Parallel() test raced against those
reads under -race (misattributed by the race detector to a whole
cluster of unrelated concurrently-running tests before this was
diagnosed). Full server package -race pass is clean after the fix.

* fix(server): decouple vis-cache reset from watch-list reload success (TASK-2533)

Codex round 4, confirmed real: on a reval tick, if ListWatchesForUser
errored, the handler's `continue` skipped visCache.reset() entirely —
the two were coupled, with reset() only reachable on the reload's
success path. A demoted or disabled user's stale identity/visibility
(round 3's fix) stayed live for exactly as long as that UNRELATED query
kept failing, so the round-3 leak reopens for the duration of any
watch-list reload error.

Fixed by running visCache.reset() first, unconditionally, before
attempting the watch-list reload. On a reload failure, the stale watch
list is kept (its own staleness is already bounded by
watchListRevalInterval's "eventually consistent" contract) but is now
gated by the FRESH visCache regardless — a demoted/disabled user is
denied via visCache even while the watch list itself lags a tick.
Chose this over dropping all delivery for the tick (the other option the
finding offered) because tying stream availability to an unrelated
query's transient health seemed like the wrong tradeoff; the comment at
the call site states this choice explicitly.

Adds a watchPredicatesLoadFault test seam on *Server (mirrors the
existing restoreAckFault pattern) so the reload failure can be forced
deterministically without breaking the DB connection for the whole test.
Reproduces the exact bug: forces the reload to fail on every tick while
concurrently disabling the connected user, and asserts addressed-to-you
delivery (which depends only on visCache, never the watch list) is
denied anyway. Fails reliably against a reverted (pre-fix, coupled)
version of the reval branch and passes cleanly against the fix.

Full server package -race pass, full suite (SQLite + Postgres) pass,
lint clean — this is the pre-PR verification matrix; round 5 will be a
narrow re-verify of this fix only.

* fix(server): bound stale watch set under persistent reload failure; atomic test seam (TASK-2533)

Codex round 5, two P2s, both confirmed real:

Finding 1 — `watches = fresh` only ran on the reload's success path, so
under a PERSISTENT (not single-tick) reload failure the watch set stayed
live indefinitely: a dead watch (removed, item deleted) kept matching
forever, and a watch created during the outage was silently missed
forever — visCache (round 4) gates current ACCESS, not whether a watch
still legitimately exists, so it couldn't catch this on its own. Fixed
by tracking consecutive reload failures and clearing the watch set once
maxConsecutiveWatchReloadFailures (3 ticks) is crossed, failing closed
on watch-matched delivery specifically while addressed-to-you delivery
(visCache-only, unaffected either way) continues throughout. Updated the
tradeoff comment at the call site so the "eventually-consistent" claim
now matches the bounded, not unbounded, behavior it actually describes.

Finding 2 — the watchPredicatesLoadFault test seam was a plain `func()
error` field, written by a test AFTER the SSE stream's background
goroutine was already running and reading it on every reval tick:
genuinely racy, unlike restoreAckFault's own use of the identical field
shape, which is set once, synchronously, before the single HTTP request
that reads it — goroutine creation's happens-before edge makes THAT
usage safe without any extra synchronization. Verified restoreAckFault
does not share the flaw and left it untouched. Fixed the watch seam with
atomic.Pointer[func() error] instead.

Test for finding 1: forces maxConsecutiveWatchReloadFailures+1
consecutive reload failures via the (now-atomic) fault seam and asserts
watch-matched delivery is suppressed once the bound is crossed while
addressed-to-you keeps delivering, then clears the fault and confirms
watch-matched delivery resumes on the next successful reload — a bounded
outage response, not a one-way ratchet. Fails reliably against the
bound disabled, passes cleanly restored.

This is the (re-run) pre-PR verification matrix per the dispatcher:
SQLite + Postgres + full-suite -race + lint + gofmt, all clean. Round 6
is a narrow re-verify of these two fixes only.

* test(store): bound the concurrent mutation-signal test's wait (TASK-2533)

CI-triage follow-up: PR #1082's plain Postgres step hit go test's default
10-minute per-binary timeout. Investigated whether any store test added by
this branch scales with runner slowness (lock-wait defaults, sleep-based
polling, transaction-hold durations):

- Watches CRUD tests (8): 0.63-0.80s each under Postgres, isolated and in
  the full 741-test package run.
- Mutation-signal tests (6), including the precheck-hook two-transaction
  race test: 0.48-0.80s each; the race test held at 0.48-0.51s across 10
  consecutive runs (no variance) and across the full-package run.
- Full store package under Postgres: 279.17s and 277.12s across two runs
  on this branch, matching the ~275s/297s baseline team-lead measured
  locally and on PR #1081 — no reproducible slowdown from anything this
  branch adds.

No pathological test found locally. The one test with genuine
cross-goroutine DB lock contention (TestLastMutation_AssignmentDelta_
NotMisattributedUnderConcurrentWrite) had an unbounded wg.Wait() as its
only unbounded wait — TX2's release was already unconditional (fixed 50ms
sleep, not gated on TX1's progress), so there's no deadlock risk, but
there was no ceiling on how long legitimate lock contention could
stretch it under a slow/shared runner. Replaced with a bounded 10s wait
that fails fast with a diagnostic instead of silently consuming
test-binary budget if it's ever exceeded. Verified the regression test
still fails reliably (5/5) against a revert of the round-2 fix it guards.

Could not reproduce the CI timeout locally; likely the pre-existing
~297s CI baseline (already noted as close to the 10-minute ceiling)
plus environmental variance on the shared runner, not a specific test
this branch adds.

David Barkhausen f900b0aefb fix(cli): address review on markdown list output
All three requested changes from @xarmian's review of #1070, plus both nits.

1. Escape backslashes before pipes in escapeMarkdownCell. A title containing
   "\|" became "\|", which GFM reads as an escaped backslash followed by a LIVE
   pipe, so the row still gained a column. Backslash-first turns it into "\\|".
   Confirmed the bug with a failing test before fixing it.

2. Sanitize the group headings. Extracted SanitizeMarkdownText (SGR strip +
   newline collapse) and ran the collection icon and name through it, so a
   newline in a collection name can no longer inject a second "## " heading.
   Sanitizing happens per part, before joining, because it trims and would
   otherwise eat the separating space. Pipes are deliberately not escaped
   outside a table.

3. Tightened the --format help to the precise enumeration:
   "markdown on: item list/starred, collection list, item show, project changelog"
   per option (a) on #898.

Nits:
- `item starred --format markdown` on an empty result now says "No starred
  items." rather than the shared renderer's "No items found."; the empty check
  moved above the format branch so both paths agree.
- Added format_markdown_routing_test.go: three end-to-end tests driving
  `item list` and `collection list` through cobra against an httptest server,
  asserting the markdown branch is actually reached and that the table and
  markdown paths don't leak into each other. Proven by disabling the markdown
  branch and watching the test fail. Follows the item_open_test.go pattern, with
  USERPROFILE set alongside HOME since os.UserHomeDir reads USERPROFILE on
  Windows — worth noting, as tests that set only HOME are why part of the
  credential-store suite fails there.

Gates: go build ./... PASS; go vet PASS; gofmt clean; golangci-lint 0 issues;
all markdown tests PASS. Both touched packages show the same 6+2 pre-existing
Windows failures as clean main under an identical sandboxed run.

David Barkhausen 4ab7b10b35 feat(cli): markdown output for the list commands
Implements `--format markdown` on the list commands that lacked it, so the
format is honestly global rather than honestly-partial (#898, the option (a)
follow-up to #851).

- `pad item list` — grouped `## Icon Name (N)` sections with a table each when
  listing across collections (mirroring the table layout), a single table when
  scoped to one collection. Heading style matches `project changelog`.
- `pad item starred` — single table.
- `pad collection list` — Name / Slug / Items / Default.
- `--format` help no longer carries the "markdown on select commands" caveat.

The markdown renderers deliberately do NOT reuse the colorized helpers
(ColorizedStatus, PriorityColor, Dim): markdown goes to a file, a PR body or an
agent's context, never a terminal, so raw values go in and the reader's renderer
styles them. Every cell is escaped — an unescaped `|` in a title silently adds a
column and corrupts the row.

Dan Finn 20b061902b fix(cli): surface actionable errors for cloud-mode setup failures
When a user picks Cloud mode during `pad init` but doesn't have a Pad
Cloud account, the CLI hits the cloud server and surfaces raw server
errors like "Missing CSRF token" — which is an implementation detail
that gives no indication of what went wrong or how to fix it.

This patch:

- Splits the ModeCloud and ModeRemote branches in printSetupRequiredHint
  so cloud users see "sign up or switch to local" instead of the generic
  "run pad auth setup on the server" message.
- Returns a cloud-specific error from pad init when setup_required is
  true in cloud mode.
- Intercepts csrf_error responses in the CLI HTTP client and replaces
  the raw server message with an actionable "run pad auth login"
  message, since the CLI never sends CSRF cookies and this error always
  indicates a stale or mismatched session.

xarmian cfc83e8c57 fix(server): report partial and legacy relationships in the copy dry-run (TASK-2369)
Two ways the cross-workspace copy preflight told a user "nothing to lose"
when there was, both violations of PLAN-2357 DR-17's "none of this may be
silent".

P1 — the five relationship counters are ACL-filtered by the caller's
collection visibility (correct, and TASK-2364 chose it deliberately), but
"none" and "none that you can see" rendered identically. A caller with
edit rights on the source and none on its relatives could read
`children_orphaned: false` and run a MOVE believing nothing was stranded,
while hidden children were orphaned in place.

The filtering stays; the uncertainty is now surfaced. Every point that
drops a relationship for visibility reasons sets a new
`warnings.relationships_partial` boolean. It is a BARE BOOLEAN by design:
how many are hidden, of what type and in which collection are exactly the
facts the filter exists to withhold, and a marker that varied with the
hidden count would reinstate the leak DR-10a, DR-10b and the moved-to
pointer each closed separately. A negative test asserts byte equality of
the whole warnings block across two workspaces that differ only in how
much is hidden. It is false for an unrestricted caller AND for a
restricted caller with nothing hidden, so the common case renders exactly
as it did before.

P2 — a child reachable only by a lone legacy `plan` edge was invisible to
GetChildItems (its join is restricted to store.ChildLinkTypes), so an
incoming `plan` relationship reported `child_count: 0` /
`children_orphaned: false` even though archiving the source strands it.
The link scan now folds such an edge into the child set, deduplicated
against the two mechanisms already covered and subject to the same
visibility, liveness and workspace guards. The outgoing direction (the
item's own parent) already reported correctly.

The mutating copy reports no relationship counters at all
(ItemCopyResultWarnings is deliberately narrower), so there is nothing for
assertPreflightMatchesCopy to disagree about.

CLI renders the qualifier on the five affected lines plus a plain-language
explanation; TS types carry the field for Phase 3's dialog.

xarmian 1e48a7a1dd feat(cli): add pad item copy for cross-workspace copy and move (TASK-2366)
Wraps PLAN-2357's two endpoints behind one command:

  pad item copy <ref> --to-workspace <slug> --collection <slug>
                      [--dry-run] [--archive-source] [--field key=value ...]

--dry-run renders the preflight's three contract buckets (carried /
dropped / needs_value) and DR-15's full warning set. Every bucket header
and every warning line prints unconditionally, zeros and empties
included: omitting a zero would make "no attachments" indistinguishable
from "this CLI does not report attachments", and DR-17's whole point is
that none of it is silent. Schema-supplied strings are escaped and list
members quoted, so a comma or newline in an option value cannot forge an
entry or a row.

--format json emits the endpoint's own response. json.Indent is a lexical
transform, so key order, unmodelled fields and int64 precision all
survive; the bytes are never round-tripped through a Go value.

DR-13, the no-retry obligation. There is no idempotency key, so a blind
re-run duplicates the item. Four mechanisms, each with a test:

  1. the mutating copy runs on its own *http.Client AND its own
     transport. The transport half is the one that matters: retry in Go
     is almost always a RoundTripper wrapper, which a merely-dedicated
     http.Client would inherit. A plain *http.Transport is cloned so
     proxy/TLS config carries; a wrapper is not used at all;
  2. its body is hidden behind an opaque reader, leaving Request.GetBody
     nil so net/http's own nothing-written replay cannot fire;
  3. redirects are refused rather than followed with the POST body;
  4. failures are classified into three exclusive outcomes, because each
     licenses a different thing to say. UNKNOWN (transport failure, 500
     copy_failed) sends the user to check the destination and never
     suggests a retry. COMMITTED-BUT-UNREPORTED (a 2xx whose body could
     not be read or decoded) exits ZERO -- a non-zero exit would tell a
     script the copy did not happen, which is the DR-13 duplicate
     arrived at through the reporting layer. A 4xx is a refusal made
     before any write and passes through plainly.

The same asymmetry governs stdout: a write failure on the dry run is an
error (nothing happened), while a write failure after the copy committed
goes to stderr and leaves the exit code at 0.

Refuse to guess. The preflight always runs first (it is read-only), and a
non-empty needs_value refuses before any mutating request, naming each
field and the exact --field flags to add. Mirrors the web dialog's
disabled confirm rather than round-tripping the user into an error they
could have been shown.

--field values are typed against the DESTINATION collection's schema, so
a number lands as a number. A malformed --field is a hard error here
rather than the silent skip `pad item create` does: this command's
contract is "you were told what to supply", and dropping a supplied value
would make the refusal a lie.

The response types in internal/cli mirror internal/server's. That is a
layering choice, not a cycle -- nothing in server imports cli, and the
mirror test imports server freely. It follows the posture already
recorded in internal/cli/bootstrap.go: this package is the HTTP client
and does not depend on the server package. An external cli_test package
walks both response shapes and fails on any JSON contract drift.

MCP is deliberately untouched: no pad_item.action: copy, and
ToolSurfaceVersion stays 0.15.

TASK-2031 + BUG-2032 (PLAN-1985). SilenceUsage + FlagErrorFunc keeps flag-error help; GetItem/UpdateItem/DeleteItem wrap not_found with ref+workspace; PersistentPreRunE rejects invalid --format; honest markdown advertising.

* fix(cli): return enriched *APIError for not_found to preserve concrete type

Team-lead P2: itemNotFoundError changed the concrete error type, so direct err.(*cli.APIError) assertions (which do not unwrap) stopped matching not_found — notably bulk-update's per-row code capture (cmd_item.go:2043), dropping code:"not_found" from the JSON envelope. Return a fresh *APIError (same Code/Details, enriched Message) instead of a wrapper type; APIError.Error() returns Message so the clean one-line message is unchanged. Both err.(*APIError) and errors.As now match. Test adds a direct-assertion + Details-passthrough lock-in.

xarmian bed933d7fd feat(items): field-level PATCH + conflict envelope + read-only version history (TASK-2022) (#876)
* feat(items): field-level PATCH + conflict envelope + version history

Adds three related item-update primitives (TASK-2022 / IDEA-1480):

- Field-level merge: PATCH `fields_patch` shallow-merges onto the item's
  current fields INSIDE the write transaction (null deletes a key), so
  concurrent single-field updates no longer clobber each other via the
  full-blob read-modify-write. `pad item update` and the MCP `pad_item.update`
  action now send only the changed keys.
- Optimistic concurrency: optional `expected_updated_at` on update; on
  mismatch the store returns *UpdateConflictError and the handler emits the
  pad-structured-error/v1 conflict envelope (HTTP 409, code=update_conflict).
  Surfaced on CLI (`--expected-updated-at`) and MCP (`expected_updated_at`).
- Read-only version history: `pad item history <ref>` (alias `versions`) and
  MCP `pad_item.history`, reusing the existing item_versions store + versions
  endpoint (no new store, no schema change).

MCP ToolSurfaceVersion bumped 0.9 -> 1.0 (new action + param; update
behavior change). No migration required.

* fix(items): address Codex review — dispatcher fields_patch, OCC ordering, date/required guards

Round 1+2 review fixes for TASK-2022:
- HTTP MCP dispatcher (dispatch_http_advanced.go) now sends fields_patch (only
  changed keys) instead of a client-side merged full fields blob, and forwards
  expected_updated_at — remote MCP callers get the same race-free merge +
  optimistic concurrency the CLI/HTTP paths do.
- ValidatePartialFields rejects null-deleting a schema-declared REQUIRED field
  (would otherwise persist a blob the full-update validator rejects).
- Open-children guard on the fields_patch path merges the patch onto the IN-TX
  locked row inside the precheck (not a stale pre-lock preview), so a
  priority-only patch can't false-fire the guard.
- Optimistic-concurrency check now runs BEFORE the open-children precheck in the
  store, so a stale expected_updated_at yields update_conflict (not
  open_children) — single in-tx re-read shared by both.
- Date auto-population on the patch path only fills an EMPTY current date; an
  existing end_date the caller isn't touching is preserved.

Tests added for each fix.

xarmian c127a5f965 fix(playbooks): enforce draft gate server-side + expose status (BUG-2020) (#874)
* fix(playbooks): enforce draft gate server-side + expose status (BUG-2020)

pad_playbook run / POST /playbooks/{ref}/run now refuse a playbook whose
status isn't "active" with a structured playbook_not_active error. Adds
an allow_draft escape hatch across all surfaces: JSON body field, CLI
--allow-draft flag, MCP boolean param, and an "allow-draft" bareword in
raw_args (stripped before strict parsing). status is now echoed on both
the run and get responses.

Bumps ToolSurfaceVersion 0.9 -> 0.10 and updates the drift-guarded docs
(instructions.md, README.md) plus CLAUDE.md.

xarmian 7aa5cb98f3 perf(bootstrap): compact JSON for agents; trim SKILL.md reference sections (#873)
Part A: `pad bootstrap --format json` now emits compact (no-indent) JSON
via a new cli.PrintJSONCompact helper. Its canonical consumer is the /pad
agent skill; pretty-print indentation was ~29% of the payload (49696 -> 35118
bytes on this workspace, saving 14578 bytes). Humans keep --format markdown.

Part B (conservative): condense the Role Awareness section and the
playbook-authoring guidance in skills/pad/SKILL.md to on-demand pointers,
keeping the load-bearing core behavior + activation gotcha inline and ALL
routing behavior intact. Saves 2764 bytes of fixed per-session overhead.

No MCP tool-surface change; ToolSurfaceVersion unchanged.

xarmian cf5eb8dd3a feat(cli,mcp): summary-shaped item list with --full opt-in + limit clamp (TASK-2000) (#842)
`pad item list --format json` returned the full models.Item shape — including
each item's rich markdown `content` body (~52% of the bytes) plus UUID plumbing
and duplicate join fields — with no default limit, so a bare agent list dumped
~1.4MB (all collections) or 5.3MB (--all) into context. The single biggest
agent-token lever.

CLI:
- JSON output now defaults to a token-light ItemSummary projection: `content`
  → short `content_preview`, UUIDs (id/workspace_id/collection_id/*_user_id/
  parent_id/agent_role_id) and duplicate collection/parent join fields dropped,
  `fields`/`tags` emitted as nested JSON. ~71% smaller on a real workspace.
- `--full` opt-in flag restores the complete models.Item shape.
- Default limit (200) + hard-max clamp (1000) so --all/huge lists can't dump
  unboundedly; a stderr note fires when a table result is capped.

MCP:
- pad_item.list is now a custom action that injects a default limit (50) and
  clamps an oversized one (max 300), mirroring the backlinks default/max, so a
  bare agent list stays bounded on both dispatchers.
- ToolSurfaceVersion 0.8 → 0.9 (list result shape + limit behavior change).

Server:
- Hard-max backstop clamp (1000) on an explicit `?limit=` at the item-list
  request boundary; no default (internal ListItems callers that fetch every
  row are untouched).

rawJSONOrNil guards against a malformed stored Fields/Tags value breaking the
whole list marshal (falls back to a JSON string).

xarmian f5b437a65f feat(server): workspace restore + deleted-list endpoints (TASK-1970) (#827)
Foundation for PLAN-1969 (user-recoverable workspace soft-delete). A
workspace delete only stamps workspaces.deleted_at; items/collections/
members are untouched, hidden transitively. Restore clears deleted_at so
everything re-surfaces intact.

Store (internal/store/workspaces.go):
- RestoreWorkspace(slug): UPDATE ... SET deleted_at = NULL WHERE slug=?
  AND deleted_at IS NOT NULL. Returns sql.ErrNoRows (-> 404) when no
  soft-deleted row matched (already live or purged).
- ListDeletedWorkspaces(userID, cutoff): owner-scoped, deleted_at within
  the window, ordered deleted_at DESC. Account-deleted workspaces have no
  live owner, so they never leak.
- GetDeletedWorkspaceBySlug(slug): resolves a soft-deleted row (the normal
  resolvers filter deleted_at IS NULL) so the handler can tell 403 from 404.
- Dual-dialect via s.q/s.dialect; no migration (deleted_at already exists).

Handlers (internal/server/handlers_workspaces.go):
- POST /api/v1/workspaces/{slug}/restore: owner-only; 404 not-restorable,
  403 non-owner, 200 + restored workspace; logs a "restored" activity.
- GET /api/v1/workspaces/deleted: owner-scoped list with per-entry
  purge_at + days_left, both derived from workspacePurgeRetention so
  restore and the purge sweeper share ONE 30-day window (no drift).
- Both routed outside the /{slug} RequireWorkspaceAccess subrouter (which
  resolves only live workspaces); restore enforces owner authz inline.

CLI client (internal/cli/client.go): RestoreWorkspace + ListDeletedWorkspaces.
TS type (web/src/lib/types/index.ts): Workspace.deleted_at + DeletedWorkspace.

Tests: store (resurface-intact; double-restore/live -> ErrNoRows; window
boundary 29d IN / 31d OUT + owner-scoping) and handler (owner-only 403,
404 live/unknown, 200 restore, owner-scoped deleted-list). Green on
SQLite and Postgres (make test-pg); golangci-lint clean.

xarmian e32bf9289b fix(cli): detect machine-level agent tools, not just project-local (BUG-1156) (#783)
DetectTools() only checked project-local dirs (.codex, .claude, etc.), so a
machine with Codex installed but no project-local dirs was invisible to
`pad init` — only the force-included Claude skill got installed. Widen
detection to OR three signals per tool: project-local dir (existing), a
home-relative dir, and a binary on PATH. Machine-level signals are only
populated for claude and agents (codex/cursor/windsurf); copilot/amazon-q/
junie keep project-local-only detection since their binaries/dirs are too
ambiguous to trust as machine-wide signals.

xarmian 665f1918a7 feat(cli): headless admin bootstrap via --email/--name/--password (BUG-988) (#761)
* feat(cli): headless admin bootstrap via --email/--name/--password (BUG-988)

Adds non-interactive flags to `pad auth setup` and `pad init` so agents
running inside Claude Code or other non-TTY environments can bootstrap a
fresh Pad instance without hitting interactive prompts that block forever.

- New flags --email, --name, --password on both commands; all three must
  be supplied together when any one is present (clear error naming the
  missing flag otherwise). Checked before the remote-mode guard so the
  headless path works on any server host — the loopback gate is enforced
  server-side.
- runHeadlessSetup() drives the existing POST /api/v1/auth/bootstrap
  endpoint directly, saves credentials, and respects --format json (emits
  a LoginResponse-shaped object with user + token). Already-initialized
  conflict produces a structured JSON error object under --format json.
- `pad init` slots headless bootstrap into the bootstrap step only; the
  rest of init (config, workspace creation, skill install) continues.
- Hardens readPassword() with an early non-TTY guard (generic message).
- Hardens promptAndBootstrap() with a bootstrap-specific non-TTY guard
  (points at --email/--name/--password flags) so --cli-prompt on a pipe
  exits immediately rather than blocking.
- Extends `pad init` non-TTY error message to mention the new flags.
- Five new tests in cmd/pad/setup_headless_test.go covering success,
  missing-flag validation, non-TTY guard, already-initialized conflict,
  and the full init flow including workspace creation.

NOTE: --password is visible in process listings (inherent to flag-based
injection). Env-var bootstrap (PAD_ADMIN_*) is the tracked follow-up.

* fix(cli): thread bootstrap token, factor shared core, restore readPassword fallback

Round-1 codex findings:

1. Bootstrap token not sent on headless path (BLOCKER)
   Add BootstrapWithToken(email, name, password, token) to cli.Client that
   sets X-Bootstrap-Token when token is non-empty. Export ReadBootstrapToken
   from internal/cli/bootstrap.go (was readBootstrapToken) so cmd/pad can
   call it. Extract doHeadlessBootstrap(cfg, client, email, name, password)
   as the shared core for both setupCmd and padInitCmd: reads the on-disk
   token best-effort (absent → empty → loopback gate still covers that case),
   calls BootstrapWithToken, saves credentials, sets auth token on client.
   Both headless paths now go through this single function — no divergence.

2. readPassword bufio fallback removed by accident (REGRESSION)
   Restore the pre-round-1 bufio fallback in readPassword so piped-password
   flows (e.g. pad auth login --interactive in CI) keep working. The bootstrap
   wedge is already prevented by the top-of-promptAndBootstrap TTY guard; the
   generic readPassword fallback is only reached by non-bootstrap callers.

3. Shared core (CLEANUP)
   padInitCmd now calls doHeadlessBootstrap instead of duplicating Bootstrap +
   saveCredentials + SetAuthToken. The --format json asymmetry (init vs setup)
   is resolved by design: pad init is a multi-step flow; for machine-readable
   bootstrap output agents should use `pad auth setup --email … --format json`.
   Documented in the inline comment on the headless branch in padInitCmd.

Tests added: TestHeadlessSetupSendsBootstrapToken, TestHeadlessSetupNoTokenFileOK,
TestReadPasswordFallback. Update internal/cli/bootstrap_test.go for the rename.

* BUG-988 round-2: surface token-read errors, wrap 403 with hint, rescope readPassword test

doHeadlessBootstrap: distinguish os.ErrNotExist (absent token → best-effort
empty, proceed without header) from other read errors (permissions, etc.
→ surface with the file path so operators can diagnose rather than silently
hitting a confusing 403). Wrap 403/forbidden from BootstrapWithToken with an
actionable multi-bullet hint covering loopback gate, token-file path, and
PAD_BYPASS_SETUP_TOKEN.

ReadBootstrapToken (internal/cli/bootstrap.go): add %w to the ErrNotExist
branch so errors.Is(err, os.ErrNotExist) propagates to callers; existing
tests and --cli-prompt hint text preserved.

TestReadPasswordFallback → TestReadPasswordBufioFallback: rescoped to assert
readPassword isolation only; added comment citing BUG-1886 (pre-existing
doInteractiveLogin double-bufio.Reader bug). BUG-1886 filed in docapp.

xarmian 22d901c823 fix(auth): unify first-run setup into one browser handoff (BUG-1843) (#739)
On a fresh instance, `pad init` / `pad auth setup` created the admin
account in the browser and dropped the operator on the console, then
printed a SECOND "authorize the CLI" URL back in the terminal that a
user who'd moved to the browser never saw — forcing a ctrl-C + re-run.

Collapse it into a single browser tab: the CLI mints the pending CLI
auth session up front and hands /setup a validated `next=/auth/cli/<code>`
target, so account creation flows straight into the approval page where
the just-bootstrapped admin approves in one click and the CLI connects.

- internal/cli/bootstrap.go: thread `next` into the /setup URL (query
  before the #token fragment); raise bootstrapPollTimeout to 20m to
  match the setup session TTL.
- cmd/pad/main.go: extract pollAndSaveCLIAuth; runBrowserSetup pre-creates
  the session and polls it; `pad workspace init` drives local setup inline.
- cmd/pad/init.go: `pad init` routes through the unified handoff.
- internal/store + internal/server: grant a setup-specific 20m CLI auth
  session TTL when UserCount==0 so the combined create-account + approve
  window can't expire mid-flow; normal logins keep the 5m default.
- web/src/routes/setup: honor a validated local `next` redirect (open-
  redirect guarded), preserved across the token-fragment scrub.

Reviewed via Codex loop (3 rounds → clean).

xarmian 248f7c5ede feat(items): expose item restore via CLI + MCP (TASK-1828) (#734)
Adds the agent-facing restore surface so an archived item discovered via
`pad item list --all` can be recovered without dropping to the web UI. The
server already had restore end-to-end (Store.RestoreItem + handleRestoreItem
at POST /items/{ref}/restore, used by the web UI and bulk ops); this wires
the two missing surfaces:

- CLI: `pad item restore <ref>` (cli.Client.RestoreItem → the existing
  endpoint, which resolves the ref include-deleted server-side). Mirrors
  `pad item delete`'s structured JSON envelope: {ref, title, restored: true}.
- MCP: pad_item action=restore via passThrough(["item","restore"]). Restore
  is non-destructive, so it's safe to expose. The action auto-joins the
  schema's action enum (derived from the Actions map) and is documented in
  the tool description.

Conflict case (slug/invocation_slug reclaimed while archived) is already
handled by handleRestoreItem (409) and surfaced by the client's
handleResponse.

Tests: restore endpoint already covered (handlers_items_test.go); restore
added to the MCP catalog<->cmdhelp bijection + dispatch tests. Child of
BUG-1791 (TASK-1827 shipped in #733).

xarmian 99b4649bb6 fix(items): surface archived items instead of masking them as missing (BUG-1791) (#733)
A soft-deleted (archived) item still appears in include-archived list
results (all=true) but 404'd on get/update/move and was absent from search
and status-filtered lists — all=true is the only read path that includes
archived rows. With no archived marker in list output and a bare "Item not
found" on get/update, this looked like index/FTS corruption (the report's
diagnosis). It is not: every read path was behaving correctly for an
archived item. The root cause is observability, not a desync.

- scanItems now scans i.deleted_at; all six feeding SELECTs select it
  (ListItems, listItemsFTS x2 dialects, getChildItems, ItemsModifiedSince,
  ListStarredItems). Archived rows in include-archived results now carry
  deleted_at so callers can tell them apart from live rows; the
  deleted_at-filtered paths are unaffected (value stays NULL there).
- GET item resolves include-deleted, returning an archived item read-only
  (200) with its deleted_at marker rather than 404 — an agent can read it
  and see it is archived.
- UPDATE/DELETE/MOVE of an archived ref return a clear 409 "archived"
  (restore first) instead of a bare 404; visibility is enforced exactly as
  the active path so an archived item is never revealed to a caller who
  can't see it.
- CLI shows an (archived) marker in lists and an Archived line in detail.

Tests: store IncludeArchived populates DeletedAt; server GET archived -> 200
with deleted_at, UPDATE/MOVE archived -> 409 "archived". Verified on SQLite
and Postgres (make test-pg).

* feat(tags): workspace tag enumeration endpoint + cross-collection filter (TASK-1653)

Foundation for the tags feature (PLAN-1652 / IDEA-1649). The write path and
per-collection ?tag= filter already existed; this adds tag enumeration and a
verified cross-collection read so a single tag can group items of any type.

- store: dialect.JSONArrayElements unnests a JSON text-array column
  (json_each on SQLite, jsonb_array_elements_text on Postgres);
  Store.ListWorkspaceTags returns distinct tags + item counts, ordered by
  count desc then tag asc, with the same collection/item ACL filters as
  ListItems so counts never leak hidden items.
- server: GET /workspaces/{ws}/tags (handleListTags), respecting collection
  visibility + guest item grants.
- models: TagCount{tag,count}.
- cli: client.ListTags + `pad tag list`.
- web: api.tags.list + TagCount type (items.list already forwards `tag`).
- tests: store-level (cross-collection aggregation, collection scoping,
  non-nil-empty = empty, archived excluded) and handler-level (a Task + an
  Idea sharing one tag; GET /tags counts + ordering).

Parent: PLAN-1652.

* fix(tags): count distinct items per tag, not tag occurrences per Codex review (round 1)

COUNT(DISTINCT i.id) so an item with duplicate tags (e.g. ["ux","ux"]) is
counted once — the write path doesn't enforce per-item tag uniqueness.
Adds a regression test.

xarmian 342679a364 Standardize plan-limit error envelope across HTTP/MCP/CLI/UI (TASK-788) (#628)
* fix: limit-hit responses were actively broken — garbled toasts, no upgrade signal

The limit enforcement responses (plan_limit_exceeded on 403) used a flat
body shape {"error": "plan_limit_exceeded", ...} that is incompatible with
every consumer: the frontend PadApiError parser, the CLI parseError path,
and the MCP classifyHTTPStatusKind all expect {"error": {"code": ...,
"message": ...}}. As a result, hitting any of the 5 plan limits (items,
members, workspaces, api_tokens, webhooks) produced garbled toasts with
undefined message text and zero upgrade signal.

Fix:
- writePlanLimitError now emits the standard nested error envelope with a
  human-readable message sentence and limit details in error.details.
- CLI parseError now correctly surfacing the message (net positive, no
  code change needed).
- MCP classifyHTTPStatusKind: adds ErrPlanLimitExceeded to the taxonomy
  and the allowedStructuredErrorCodes whitelist so 403 plan-limit errors
  pass through with code + details rather than collapsing to
  ErrPermissionDenied (TASK-788).
- Frontend: exports isPlanLimitError() type-guard and planLimitMessage()
  formatter from client.ts; all 4 limit-hit write call sites (item create,
  member invite, workspace create, token create) now branch on the code and
  show an upgrade-signal message pointing at /console/billing.
- Test: updates handlers_workspace_cap_test.go to the new body shape; adds
  TestPlanLimitError_ResponseShape covering members_per_workspace limit hit.

TASK-788

* fix(R1): cover MCP stdio path, 5 more item-create sites, polish message wording

Finding A — MCP stdio transport was missing plan-limit coverage:
- cli/client.go: add PlanLimitDetails struct, AsPlanLimit() helper, and
  WritePlanLimitError() that emits the pad-structured-error/v1 marker so
  the MCP stdio classifier can lift code + details instead of falling
  through to ErrServerError.
- cmd/pad/main.go: wire the WritePlanLimitError branch into all three
  CreateItem call sites (item create, convention activate, playbook activate).
- internal/mcp: add TestClassifyHTTPStatus_PlanLimitPreservesCodeAndDetails,
  TestClassifyHTTPStatus_Generic403FallsToPermissionDenied,
  TestClassifyExecError_PlanLimitMarkerLiftsStructuredPayload, and
  TestClassifyExecError_PlanLimitWithoutMarkerFallsThrough.

Note: extractUpstreamErrorEnvelope already parses details (json.RawMessage
field) — the codex concern about it being silently empty was a false alarm;
no fix needed there.

Finding B — 5 more item-create entry points were unguarded:
- EditorBubbleMenu.svelte (inline wiki-link capture)
- Sidebar.svelte (quick-add)
- roles/+page.svelte (board new-item, was console.error only; adds toastStore)
- conventions/+page.svelte
- playbooks/+page.svelte (both create and duplicate paths)

B1/B2 polish — server message is now statement-of-fact only, no doubled
upgrade verb. planLimitMessage() drops "Upgrade to Pro to add more." (each
surface appends its own CTA). limitStr uses hyphenated adjective form
"3-member" / "10-item" (compound modifier before "limit").

TASK-788

* feat(task-788): extend MCP-stdio plan-limit coverage to workspace, invite, webhook

Wire WritePlanLimitError into three additional CLI command error paths so
the MCP stdio classifier surfaces ErrPlanLimitExceeded with details instead
of falling through to ErrServerError:

- workspaceCreateCmd: check before fmt.Errorf wraps the APIError
- inviteCmd: check before returning the raw error
- webhooksCreateCmd: check before returning the raw error

Add TestClassifyExecError_PlanLimitWorkspaceCreate to exercise the full
workspace-create stdio round-trip through classifyExecError, asserting
ErrPlanLimitExceeded code, feature="workspaces", limit, and upgrade_url.

Token create intentionally left bare (agents don't drive token creation).

xarmian 8e7d4040fd feat(backlinks): server-side reverse index for [[...]] (Phase 1) (#620)
* feat(backlinks): server-side reverse index for [[...]] wiki-links (Phase 1)

First phase of PLAN-1593. Today [[REF]] is parsed only at render time
on the client and there's no way to ask "who links to TASK-5?" without
a full-text scan. This change adds a materialized reverse index
(item_wiki_links) that's written every time an item's content changes
and exposes it via REST + CLI.

Phase 1 covers ref-form links only (`[[TASK-5]]` / `[[TASK-5|Display]]`).
Phase 2 (TASK-1595) will extend to titles + cross-workspace; Phase 3
(TASK-1596) adds the web UI panel + MCP action.

What lands here:

* Migrations 061 (SQLite) and 040 (Postgres) create item_wiki_links
  with partial indexes on target_item_id, (target_workspace_id, target_ref),
  and target_title — the schema accommodates all 5 wiki-link forms
  up-front so Phase 2 doesn't ALTER.

* internal/links/extract.go is the canonical parser. It strips fenced
  and inline code regions before extracting [[...]] occurrences, so
  example refs in docs / code blocks don't pollute the index. Phase 1
  emits only WikiLinkKindRef rows; title and workspace_ref kinds parse
  successfully but are gated out until Phase 2.

* internal/store/wiki_links.go (replaceWikiLinks + GetBacklinks +
  helpers) handles write-time bookkeeping and the read query. Resolution
  to target_item_id happens at parse time inside the same transaction
  as the items INSERT/UPDATE, so partial state never lands. Broken refs
  (target_item_id IS NULL) intentionally persist — they feed a future
  broken-links report.

* internal/store/wiki_links_backfill.go + cmd/pad/main.go hook the
  idempotent backfill into server startup. Existing items get indexed
  on first boot after the migration; subsequent boots are near-no-ops
  via an EXISTS short-circuit.

* internal/store/items.go is amended in two places: tryCreateItem
  always calls replaceWikiLinks (empty content → no-op DELETE), and
  UpdateItemWithPreCheck re-parses whenever input.Content was supplied.

* internal/server/handlers_backlinks.go serves
  `GET /api/v1/workspaces/{ws}/items/{itemSlug}/backlinks` with
  visibility + guest-grant filtering on the source items.

* internal/cli/client.go adds GetBacklinks; cmd/pad/main.go adds the
  `pad item backlinks <ref>` command (registered in groups.go).

Behavior decisions (per PLAN-1593):
- code blocks excluded (fenced + inline)
- self-links filtered at query time (kept in storage)
- repeated mentions stored as separate rows by position
- ordering: source updated_at DESC, position ASC

Tests:
- internal/links/extract_test.go: 26 sub-cases covering ref/title/
  workspace-ref discrimination, code-block exclusion (fenced + inline +
  unclosed fence), position-is-byte-offset (UTF-8 safety), and edge
  inputs.
- internal/store/wiki_links_test.go: 8 integration tests covering the
  create/update/delete/self-link/broken-ref/repeated/code-block
  scenarios plus backfill idempotence.

All pass. `make check` clean (lint + go test + web build).

Refs: TASK-1594, PLAN-1593, IDEA-1577

* fix(backlinks): visibility-aware pagination + case-insensitive refs per Codex review (round 1)

Two fixes from Codex code review:

P1 — GetBacklinks now takes a visibleCollectionIDs []string argument
that's applied INSIDE the SQL WHERE clause. Previously the handler
fetched LIMIT raw rows and filtered visible ones in Go, so a
restricted user asking for limit=50 could receive an empty page even
when later visible backlinks existed. Pushing visibility into SQL
makes LIMIT/OFFSET count visible rows.

  nil  → no restriction (owners, editors, root tokens)
  []   → see nothing (returns early, no SQL)
  [..] → AND s.collection_id IN (?, ?, ...)

Item-level guest grants still apply post-fetch — they're rare enough
that the residual page shrink is acceptable and pushing them into SQL
would balloon the query.

P2 — refPattern now accepts mixed/lowercase refs and parseBody
canonicalizes the prefix to uppercase at the single chokepoint.
Previously the renderer accepted `[[task-5]]` as a real link (its
REF_PATTERN is case-insensitive) but the indexer's ^[A-Z]... pattern
silently dropped it — divergent parsing on the same input. Storage
shape is canonical uppercase so the (workspace, prefix, number)
lookup against collections.prefix (also uppercase) has one shape.

New helper: canonicalizeRef("task-5") → "TASK-5".

Regressions:

  internal/links/extract_test.go
    + TestCanonicalizeRef                 — helper unit tests
    + TestExtractWikiLinks_RefVsTitleFallback updated to assert
      mixed/lowercase parses-as-ref-and-uppercases
    + edge-case test renamed from "lowercase ref" to "number-led
      not a ref" (lowercase IS a ref now per Codex P2)

  internal/store/wiki_links_test.go
    + TestWikiLinks_MixedCaseRefIndexed   — `[[task-5]]` produces a
      backlink row whose target_ref is "TASK-5"
    + TestWikiLinks_VisibilityAwarePagination — three sub-cases:
      nil → all 3, visible-only limit=2 → 2 visible rows (not 1 with
      hidden one consuming a slot), empty → 0

All call sites updated (8 in tests + 1 in handler).

`make check` clean (lint + tests + web build).

* fix(backlinks): SQL-level item-grant filter per Codex review (round 2)

Round 1 fixed pagination for collection-level visibility but Codex
round 2 correctly flagged the same class of bug at the item-grant
layer: `visibleCollectionIDs` returns the UNION (full grants ∪
collections containing granted items), and the handler then
filtered each row's item-level visibility in Go AFTER fetching —
letting hidden rows in a granted-item's collection consume LIMIT
slots.

The refactor moves the precise predicate into SQL. New shape:

  type BacklinksVisibility struct {
      Unrestricted      bool      // admin / full-access member
      FullCollectionIDs []string  // direct collection grants
      GrantedItemIDs    []string  // item-level grants
  }

  // SQL predicate when Unrestricted=false:
  //   AND (s.collection_id IN (?...)  OR  s.id IN (?...))

This matches `guestResourceFilter` (which returns the precise
primitives), so the handler now passes them straight through and
drops the post-fetch filter loop entirely. Pagination is correct
for guests, restricted members, and unrestricted users alike.

New test:

  TestWikiLinks_ItemGrantPagination — guest with item-grant on ONE
  item in an otherwise-hidden collection sees exactly that one item;
  hidden siblings in the same collection do NOT leak in, and limit=2
  returns 1 row (not silently shrunken).

Other call sites updated:
- TestWikiLinks_VisibilityAwarePagination → uses
  BacklinksVisibility{FullCollectionIDs: ...} and
  BacklinksVisibility{} for the no-access case.
- 8 existing tests → BacklinksVisibility{Unrestricted: true}.
- handlers_backlinks.go → no longer calls visibleCollectionIDs;
  uses guestResourceFilter exclusively and skips the Go-side filter.

* fix(backlinks): scan EXISTS into bool not int for Postgres parity (Codex round 3)

`SELECT EXISTS(...)` returns boolean on Postgres but integer 0/1 on
SQLite. Scanning into `int` happened to work on SQLite (the modernc.org
driver coerces) but would fail on Postgres — silently disabling the
backfill short-circuit there and meaning upgraded Postgres installs
wouldn't populate backlinks for pre-existing content until each item
got edited.

Fix: scan into bool. Both database/sql drivers in use (modernc.org/
sqlite and lib/pq) coerce their native representation into Go's bool,
so this single shape works on both engines.

* fix(backlinks): allow CommonMark 0-3 space indented fences per Codex (round 5)

Round 5 flagged two edge cases in the code-stripping pass:

1. Multi-backtick inline code (``see [[X]]``) — traced through the
   parser; my permissive close-on-next-backtick logic already covers
   it correctly (range = [opener-start, after-closer-run]). Added
   a regression test to lock this in:
     TestExtractWikiLinks_CodeBlocksExcluded /
       "multi-backtick inline code excludes ref"

2. Indented fenced blocks — CommonMark allows 0-3 leading spaces of
   indentation before a fence opener (4+ spaces makes it an indented
   code block, a different construct). My fencedCodeRanges only
   matched fences at column 0, so `   ```\n[[X]]\n```` ` would
   render as code in the UI but leak a false backlink. Fixed both
   fencedCodeRanges (opener) and findFenceCloser (closer) to skip
   up to 3 leading spaces, with a hard cap at 4 (which would be
   indented-code, not a fence). Regression test:
     TestExtractWikiLinks_CodeBlocksExcluded /
       "indented fenced block (CommonMark 0-3 spaces)"

Not addressed:
- Round-4 escape-body parity finding. extract.go mirrors
  renderMarkdown's regex (web/src/lib/utils/markdown.ts:300), which
  is the actual render-time link parser; wikiLinksToMarkdown's more
  permissive escape grammar is editor-serializer-side and the
  renderer can't even consume its escaped output. Indexing what the
  user actually sees as a link is the correct invariant.

make check clean.

Refs: TASK-1594, PLAN-1593

* fix(backlinks): tilde fences + strict closer lines per Codex (round 6)

Two CommonMark conformance gaps in the code-block stripping pass:

1. Tilde-fenced code blocks (~~~) were ignored. marked() treats them
   the same as backtick fences, so a [[REF]] inside a tilde block
   would render as code in the UI but leak as a false backlink.
   Fixed by parameterizing fenceChar across fencedCodeRanges and
   findFenceCloser, with separate handling for the backtick-specific
   "no backtick in info string" rule (CommonMark §4.5).

2. Closer-line strictness — CommonMark requires the closing fence
   line to contain only the fence + optional trailing spaces. The
   previous accept-any-fence-prefixed-line check would terminate
   a still-open fence prematurely on a line like ```not-closed,
   leaking later refs in the still-rendered code block.

Refs reside in 4 new sub-tests under TestExtractWikiLinks_CodeBlocksExcluded:
- tilde fence excludes refs inside
- tilde fence with language tag
- mixed fence types don't pair
- closer-line strictness — backticks plus other text is not a closer
- closer-line strictness — trailing spaces OK

* fix(backlinks): inline code closer must match opener length per Codex (round 7)

CommonMark §6.1 requires an inline-code span opened with N backticks
to close on a run of EXACTLY N backticks. The previous "close on next
backtick run of any length" logic would prematurely end the excluded
range on a stray single backtick inside a ``...`` span, leaking any
[[REF]] in the latter half of the code text as a false backlink.

Concrete failure case:
  ``has ` inside [[X-1]] and more``
  → old: range [0, 7], [[X-1]] indexed (bug)
  → new: range [0, end-of-closer], [[X-1]] excluded (correct)

Fix: track the opener-run length and scan only for matching-length
closer runs. Wrong-length runs in between are code text.

Two new regression sub-cases under TestExtractWikiLinks_CodeBlocksExcluded:
- inline code closer matches opener length — the main case
- single-backtick span unaffected by adjacent multi-backtick run —
  asserts the opposite direction (opener=1 doesn't close on ``)

Not addressed:
- Re-flagged round-4/round-7 escape-body parity finding. extract.go
  intentionally mirrors renderMarkdown's regex (markdown.ts:300), not
  wikiLinksToMarkdown's more permissive escape grammar (markdown.ts:461).
  renderMarkdown is the actual link parser at display time; its regex
  rejects escaped-`]` bodies, so any link with an escaped `]` in its
  body is NOT shown as a clickable link in the UI. Indexing it would
  produce phantom backlinks the user can't see. The wikiLinksToMarkdown
  permissive grammar is paranoid serialization that the renderer can't
  consume — that's a pre-existing inconsistency in the editor pipeline,
  not a backlinks bug.

Refs: TASK-1594, PLAN-1593

* fix(backlinks): rune-align snippet end-edge to keep UTF-8 valid (Codex round 8)

The previous snippetAround() trimmed `start` to a rune boundary (so
the leading edge of the snippet was always at a valid codepoint) but
left `end` as a raw +40-byte clamp. When that landed in the middle of
a multi-byte rune — common around emoji or accented text — the
resulting slice was invalid UTF-8 and the JSON encoder would emit
replacement characters in backlink snippets.

Fix: same forward-advance pattern at the end as at the start.
Continuation bytes (10xxxxxx) get skipped until we land on a leading
byte. Going forward keeps the snippet anchored slightly past the
match rather than slightly before it, which is a small UX win
(emoji or accented text right after the link survives intact).

Regression test:
  TestWikiLinks_SnippetIsValidUTF8 — pads body with enough 4-byte
  emoji on each side that the ±40-byte window cuts through one;
  asserts utf8.ValidString on the resulting snippet.

* fix(backlinks): inline code spans cross newlines, break on blank lines (Codex round 9)

CommonMark §6.1: an inline-code span can cross single newlines but
terminates at a blank line (a line containing no chars or only
whitespace, which ends the enclosing paragraph). My previous scanner
broke at every newline, so multi-line spans like

    `pre
    [[INSIDE-1]]
    post`

would treat the opener as unclosed and leak [[INSIDE-1]] as a false
backlink. Fixed by:

  1. The newline branch in the closer scan now peeks ahead via the
     new isBlankLineAt() helper. Same-paragraph newlines are
     traversed; blank-line breaks terminate the span unmatched.
  2. isBlankLineAt() treats any line with only space/tab as blank
     (mirroring CommonMark's blank-line definition).

Three new regression sub-cases under TestExtractWikiLinks_CodeBlocksExcluded:
  - inline code spans single newline (CommonMark §6.1)
  - inline code breaks at blank line (paragraph boundary)
  - inline code breaks at whitespace-only blank line

Trade-off: a truly-unclosed inline backtick now consumes from the
opener up to the next blank line instead of just the rest of the
line. False-positive on wiki-links in that span, but the surface
area is small (unclosed backticks are rare in published prose) and
matches the renderer's behavior.

Refs: TASK-1594, PLAN-1593

* fix(backlinks): accept escaped wiki-link bodies per editor grammar (Codex round 10)

After 3 rounds of disagreement, capitulating on the escape-body parity
finding. My position was technically correct for the CURRENT
renderMarkdown behavior (which uses [^\]]+ and can't parse escaped-
bracket bodies), but the editor's wikiLinksToMarkdown grammar at
markdown.ts:461 explicitly produces such bodies — making the
renderer's regex the inconsistent half of the pipeline, not mine.

Mirroring the editor's grammar in the extractor makes the index
forward-compatible: when the renderer eventually gets fixed, no
change here is needed. The cost is a few "phantom" rows in the
interim (indexed links the renderer doesn't currently display as
clickable), but those are harmless and aligned with author intent.

Changes:
- wikiLinkPattern now uses `\[\[((?:\\.|[^\]\\])+)\]\]` — mirrors
  markdown.ts:461 verbatim.
- New splitOnUnescapedPipe() helper — scans for the first `|`
  that isn't preceded by `\`. Mirrors splitWikiBody at
  markdown.ts:664.
- New unescapeWikiBody() helper — undoes `\]`, `\|`, `\\` escapes
  in display text and key. Mirrors unescapeWikiBody at markdown.ts:657.
- parseBody() now uses both helpers — split on unescaped `|`,
  unescape both sides.

Regression coverage:
- TestExtractWikiLinks_EscapedBodyChars (5 sub-cases): escaped `]`,
  escaped `|`, escaped `\`, non-escape backslash passes through,
  Position still points at opening `[[` despite escapes.
- TestSplitOnUnescapedPipe + TestUnescapeWikiBody: direct unit
  tests for the helpers (round-trip safety vs the editor's
  escape/unescape pair).

* fix(backlinks): preserve display text verbatim per Codex round 11 P3

The previous parseBody trimmed the display side of [[X|Display]] but
the WikiLinkRef.Display contract promises verbatim storage and the
renderer at markdown.ts doesn't trim either. Trimming would silently
diverge on padded display text like [[TASK-1|  spaces  ]] (renderer
keeps the spaces, extractor stripped them).

Fix: drop TrimSpace from the suffix half of the split. Keep trimming
the key/ref side because refPattern is anchored — a leading or
trailing space in the key would force the body to fall through to
the title kind even though the renderer resolves it as a ref.

Regression test:
  TestExtractWikiLinks_EscapedBodyChars / "display text preserved
  verbatim (no TrimSpace)"

* fix(backlinks): distinguish empty display override from no-pipe per Codex round 12

[[REF|]] (explicit empty display) and [[REF]] (no display) are distinct
shapes in the editor: splitWikiBody returns displayOverride="" for the
former, null for the latter, and the renderer uses `displayOverride ??
title` (nullish coalescing, NOT empty-string fallback) so "" is
preserved. The previous extractor collapsed both into display_text=NULL,
violating verbatim-display preservation for the empty-string edge case.

Fix:
- WikiLinkRef gains a HasDisplay bool. parseBody sets HasDisplay=true
  iff splitOnUnescapedPipe found a pipe; downstream uses HasDisplay
  (not Display!="") to decide whether to persist the override.
- replaceWikiLinks in store: NullString.Valid is keyed off HasDisplay.
  display_text='' for explicit empty, NULL for no override.

Regression coverage:
- internal/links/extract_test.go:
    "explicit empty display override is distinguished from no pipe"
- internal/store/wiki_links_test.go:
    TestWikiLinks_EmptyDisplayDistinct (two-source assert: NOT NULL
    for [[REF|]], NULL for [[REF]])

make check clean.

Refs: TASK-1594, PLAN-1593

* fix(backlinks): pointer-typed DisplayText to preserve empty distinction over JSON (Codex round 13)

Round 12 added HasDisplay on the parser side and made the store
preserve display_text='' vs NULL on the DB row, but the wire model
collapsed the distinction at JSON-serialization time:

    DisplayText string `json:"display_text,omitempty"`

`omitempty` drops empty strings, so [[REF|]] (empty override) and
[[REF]] (no override) serialized identically on the API and CLI JSON
output. The end-to-end goal of round 12 wasn't reached.

Fix: change DisplayText to *string. nil → no override (field omitted
from JSON via omitempty), pointer to "" → explicit empty override
(field present with empty value). The store's NullString.Valid drives
the assignment, so the SQL round-trip matches the JSON shape.

Knock-on: the CLI's `pad item backlinks` now dereferences the pointer
and prints both populated and empty overrides ("displayed as: ").

Regression coverage:
- TestWikiLinks_EmptyDisplayDistinct extended to assert
  withBL.DisplayText is non-nil-pointing-at-"" and noBL.DisplayText
  is nil after a GetBacklinks round-trip.

xarmian de1beb47a9 feat(cli): pad library get + list --full + server-side category filter (TASK-1562) (#613)
CLI layer for PLAN-1560 (`pad_library` MCP tool + matching CLI surface).
Wires the HTTP work landed in TASK-1561 through to the `pad library`
subcommands.

## `pad library list` changes

- `--category` is now a server-side filter (the old client-side
  display-only skip-loop is dead and removed).
- New `--full` flag. Default JSON output for playbooks now returns the
  `summary` field (first non-heading paragraph, ~240 char cap) instead
  of the full `content`; `--full` opts back into full bodies for
  callers that want to pipe everything.
- Table output gains a summary hint line under each playbook and a
  `/pad <slug>` chip when an invocation slug is declared, so the
  library becomes self-documenting as a discovery surface.
- `--type` now validates explicitly instead of silently producing an
  empty list for unknown values.

## NEW `pad library get <title>`

Calls `GET /api/v1/library/entry?title=X` and renders either a
conventions card (title, category, trigger, surfaces, enforcement,
commands, body) or a playbooks card (title, category, trigger, scope,
invocation slug, argument count, body). Conventions-first precedence
matches `pad library activate`.

JSON output returns the full envelope.

404 errors return a clean `not found in library: "<title>"` message
with exit code 1.

## CLI client

- `GetConventionLibrary(category)` — pass category as a server-side
  query param.
- `GetPlaybookLibrary(category, summary)` — same plus the summary
  toggle; `summary=true` strips Content and returns Summary instead.
- NEW `GetLibraryEntry(title)` returning `*LibraryEntryResponse`.
- `LibraryPlaybook` gained an omitempty `Summary` field so a single
  type round-trips both the legacy and summary shapes.

## Drive-by

Switched `/library/entry` 400/404 from a flat `{error: "..."}` body to
the canonical `writeError(code, message)` envelope used by the rest of
the API. The CLI's `parseError` now hands back a typed `APIError` that
`pad library get` pattern-matches on `Code=="not_found"` for the clean
404 message. Updated `TestLibraryEntry_MissingTitle` and `_NotFound`
to assert the new envelope.

## Verification

go build / go vet / go test ./... all green. golangci-lint clean on
cmd/pad/..., internal/cli/..., internal/server/.... End-to-end smoke
tests via the installed binary confirmed: list summary mode, list
--full, list --category filter, get convention card, get playbook
envelope, get 404 exit-1, --type validation.

xarmian db87b47754 fix(cli): pin server URL in .pad.toml for remote workspaces (BUG-1535) (#595)
* fix(cli): pin server URL in .pad.toml for remote workspaces (BUG-1535)

Two fixes:

1. Replace stale api.getpad.dev references with app.getpad.dev in the
   --url flag help, NewClientFromURL doc, and Config.URL doc. Also fix
   internal/mcp/dispatch_http.go's comment to use the canonical
   mcp.getpad.dev/mcp URL.

2. Persist the server URL into .pad.toml when linking a directory to a
   non-local workspace. WriteWorkspaceLink now takes a serverURL arg;
   pad init / workspace link / workspace switch pass cfg.BaseURL() when
   Mode != local. getConfig() reads .pad.toml's URL as an override above
   ~/.pad/config.toml and below the --url flag, so commands like
   `pad collection list` from a remote-linked directory hit the right
   server without --url on every call. Passing --url explicitly also
   promotes local → remote so the directory pin is written even when
   the existing global config has mode=local.

* fix(cli): scope .pad.toml URL override to client paths per Codex review (round 1)

Round 1 review flagged that applying the .pad.toml URL override inside
getConfig() contaminates server/admin commands: pad server start would
advertise the wrong PublicLinkBaseURL, and pad auth setup would refuse
to run locally because Mode flipped to remote.

Extract the override into applyPadTomlOverride() and call it only from
client-API entry points — getConfiguredConfig() and the pad init client
phase. Server/admin commands (pad server start/stop, pad auth setup,
pad auth configure) keep using raw getConfig() and are unaffected. Also
skip the override when --url was explicitly passed (LoadedFromFlags),
so the flag retains unambiguous priority.

* fix(cli): preserve .pad.toml URL on workspace link/switch per Codex review (round 2)

Round 2 review noted workspace link / workspace switch reached the
server via getClient() (override applied) but then wrote the new
.pad.toml URL using a raw getConfig() — which would drop or miswrite
the url field when relinking inside a remote-pinned directory whose
global config is local. Reuse the cfg returned by getClient() for
padTomlURLFor so the write matches the API client.

xarmian aec67e202e feat(mcp): workspace.create + workspace.claim actions + claim-code mechanics (TASK-1521) (#582)
Phase B for PLAN-1519. Adds two MCP actions so agents can bring a
workspace into an OAuth connection without re-auth — the agent-first
onboarding story IDEA-1517 §1 set out to fix.

pad_workspace.action: create
- New action on the shared catalog (stdio + cloud both pick it up).
- POSTs to /api/v1/workspaces; handler auto-adds the new workspace to
  the calling OAuth connection's allow-list (added_by='agent-create')
  when the grant carries may_create_workspaces=true. Phase A wired the
  oauth_connection_workspaces table this writes to. PAT / CLI-session
  callers fall through silently (no request_id → no side effect).
- Backed by a new non-interactive `pad workspace create <name>` Cobra
  command for the stdio MCP shell-out path. `pad workspace init`
  remains the guided human flow.

pad_workspace.action: claim
- New POST /api/v1/oauth/claim endpoint redeems a 6-digit stateless
  HMAC code minted from (user_id, workspace_id, 5-min time bucket)
  with a sliding 5–10 minute lifetime. Constant-time compare. Code
  format derived per IDEA-1517 §4.
- Verifies workspace membership before code (privilege-escalation
  guard); uniform 404 envelope so the endpoint can't be used to probe
  existence vs. membership.
- Side effect inserts a row in oauth_connection_workspaces with
  added_by='claim'. Idempotent — re-claiming returns 200 with
  already_added=true.
- 412 connection_not_persisted when the OAuth grant predates Phase C
  (no oauth_connections row); 412 claim_disabled when the deployment
  hasn't wired SetClaimSecret.
- `pad workspace claim <code> --workspace <slug>` Cobra command backs
  the stdio MCP shell-out.

MCP server instructions
- Appended IDEA-1517 §5 paragraph teaching agents the claim flow as
  a peer top-level section. Same string lands universally on every
  MCP handshake response (stdio + cloud both read instructions.md).

Tests
- 10 claim-code unit tests: determinism, zero-pad, length-prefix
  collision guard, current/previous bucket accept, aged-out reject,
  wrong-everything rejects, short-secret fails closed.
- 7 handler tests: 412 when secret disabled, 400/404/401 vocabulary,
  PAT caller note path, 412 connection_not_persisted, idempotent
  insert.
- 5 MCP-catalog tests: actions registered, schema params advertised,
  description mentions both actions, route mappers produce correct
  HTTP shape, routeTable carries the entries.
- Bumped the existing read-only catalog bijection + fixture-input
  fixtures so the new actions resolve cleanly.

xarmian f76520f6e7 feat(cli,mcp): expose 'collection delete' via CLI and MCP catalog (TASK-1511) (#573)
* feat(cli,mcp): expose 'collection delete' via CLI and MCP catalog (TASK-1511)

Mirrors TASK-1510 (collection update). The HTTP handler at
handlers_collections.go::handleDeleteCollection already supported
DELETE on a collection (owner-only, soft-deletes the collection and
every item in it). Wires both agent-facing surfaces:

- internal/cli/client.go: new DeleteCollection client method.
- cmd/pad: new 'pad collection delete <slug>' Cobra subcommand
  (no --force; the help text is the confirmation contract).
- internal/mcp/catalog_collection: 'delete' action passes through
  to the CLI; tool description updated.
- internal/mcp/dispatch_http_routes: simple routeSpec entry for
  DELETE /api/v1/workspaces/{workspace}/collections/{slug}. No
  custom mapper needed — no body, no field coercion.

Pairs with TASK-1510 as the second adaptation primitive for the
/pad onboard playbook (TASK-1499): when the onboard interview
discovers a seeded collection that doesn't fit the project, the
agent now has a way to remove it before creating the right one.

Tests:
- TestRouteTable_CollectionDelete (route substitutes correctly)
- catalog_readonly bijection + liveCmdhelpDoc fake updated.

Parent: PLAN-1496.

* docs: correct collection delete contract per Codex review (round 1)

Two findings on PR #573 — both documentation, no code behavior change:

1. CLI Long help / Short blurb / MCP description claimed delete
   "removes seeded collections" and the onboard use case targets
   template-seeded collections. But store.DeleteCollection refuses
   any collection where is_default=true, and every template seed is
   is_default=true. The advertised use case wouldn't actually work.
   Updated docs to clarify: delete is for USER-CREATED collections;
   template seeds must be adapted via 'pad collection update'.

2. Both CLI help and MCP description claimed "AND every item in it"
   gets archived. The store delete path only sets collections.deleted_at
   and never touches items. The web UI hides them via the join, but
   raw API queries still surface them. Updated docs to be honest:
   items are NOT cascaded.

Captured the underlying behavior limitation as a follow-up: IDEA-1513
("Lift is_default restriction on collection delete or add a
cascade-items option") — surfaces options 1-4 for lifting the guard
plus the items-orphan issue.

Parent: PLAN-1496, addressing Codex round 1 on PR #573 / TASK-1511.

* docs: tighten collection delete contract per Codex review (round 2)

Three P3 documentation-drift findings:

1. internal/cli/client.go::DeleteCollection Go doc still said "and
   all items in it" — missed it in round 1. Updated to describe the
   actual behavior (collections.deleted_at only; items orphaned with
   soft-deleted collection_id; is_default rejected).

2. CLI Long help and MCP description claimed restore is available
   "via the API," but there is no restore endpoint and no
   RestoreCollection client method. Recovery is database-backup only.
   Both docs updated.

3. catalog_collection.go:33 slug ParamDef only mentioned action=update;
   action=delete needs it too. And the headline description still
   said "list, create, and update" — three actions when there are
   now four. Both fixed.

* docs: update pad_collection action lists in instructions.md + README (round 3)

Codex round 3 finding: two top-level reference docs still advertised
pad_collection as list/create only. internal/mcp/instructions.md is
embedded into the MCP initialize() handshake instructions — stale
guidance there means MCP clients miss update/delete entirely. README's
catalog table had the same drift.

Escape hatch: `--force` on `pad item update` / `pad item bulk-update`
and `force: true` on the MCP pad_item.action: update / bulk-update
inputs both forward into the same ItemUpdate.Force transport field
the handler consumes before any store mutation.

Trigger conditions are tight: the PATCH must change the done-field key
(resolved via TerminalValuesForDoneField against the parent's schema +
settings) AND the new value must be terminal AND the current value
must NOT already be terminal. Terminal → terminal and no-op terminal
transitions bypass the guard; only entering the terminal set is gated.
Per-child evaluation uses the child's own collection schema so
hierarchical workspaces with custom typed collections work without
extra plumbing.

Tests cover: rejection with one open child (with mutation-safety
assertion on the parent), no children, all-terminal children, --force
override, no-op terminal → terminal, terminal → terminal,
non-terminal → non-terminal, custom collection terminal_options
honored, and a parent task (not a plan) — IDEA-1494 optional extra #3.
MCP coverage asserts --force round-trips through both ExecDispatcher
and HTTPHandlerDispatcher and is omitted when force=false.

* fix(server): open-children guard round 2 — visibility, MCP pass-through, TOCTOU (IDEA-1494)

Three Codex round-1 issues, each fixed with the recommended shape:

P1 — visibility leak. The 409 response previously listed every blocking
child by ref/title/status, including children in collections the caller
couldn't see. The INVARIANT still evaluates against ALL children (it's a
data-integrity gate — a restricted user must not be able to close a
parent whose blockers they can't see), but the response payload now
filters to caller-visible children only. Hidden blockers surface as a
new `details.hidden_blocker_count` field plus an alternate human message
when every blocker is hidden ("blocked by N open children you don't
have access to"). Mirrors the visibility helpers (`visibleCollectionIDs`
+ `isItemVisibleToGuest`) used by the per-parent progress endpoint so
the two paths can't drift.

P2 — MCP code/details pass-through. The HTTP classifier was collapsing
409 into the generic `conflict` code and dropping `details`; the stdio
classifier was matching the human "cannot " message against the
validation regex and surfacing `validation_failed`. Both now surface
`open_children` with the structured details intact:
  - HTTP: classifyHTTPStatusKind's 409 branch extracts the upstream
    code; any non-empty, non-"conflict" code is passed through with
    its `details` RawMessage. Generalizes beyond open_children — any
    future structured 409 from a handler gets the same treatment.
  - Stdio: the CLI writes a `pad-error: {json}\n` marker line on
    stderr before the human-readable block (single source of truth for
    both views), and classifyExecError detects the marker and lifts
    the envelope verbatim. Marker is duplicated as a const between
    internal/cli and internal/mcp to avoid pulling the cli package
    into the classifier just for one string.
A new ErrOpenChildren error code constant + `Details json.RawMessage`
field on ErrorPayload back the wire shape.

P2 — TOCTOU. The guard previously ran in the handler before the store
transaction began; a concurrent child insert / child status flip could
slip between the children-list read and the parent's UPDATE. Fix:
  - New `Store.UpdateItemWithPreCheck(id, input, precheck)` runs the
    caller's invariant check inside the same tx, after acquiring the
    workspace seq lock AND a new parent-children advisory lock keyed
    on the parent ID. UpdateItem is now a thin wrapper passing nil.
  - Every UpdateItem unconditionally acquires the parent-children
    advisory lock for its own parent (if any) AND for itself-as-parent,
    in a fixed order (parent first) so two updaters touching the same
    parent always grab that key before the more-specific one — no
    AB/BA deadlock.
  - New `GetChildItemsTx` reads via the caller's tx; on Postgres the
    advisory lock provides the snapshot guarantee (DISTINCT precludes
    `FOR UPDATE`), on SQLite the global BEGIN IMMEDIATE write lock
    serializes all writers.
  - Handler now passes a precheck closure into UpdateItemWithPreCheck
    at all three call sites (collab-snapshot path, applier-direct-write
    path, main path). The guard's openChildrenGuardError sentinel is
    unwrapped after each call so the 409 surfaces cleanly.

Tests:
  - TestOpenChildrenGuard_VisibilitySanitizesPayload — restricted
    editor sees parent + visible child, hidden child contributes to
    hidden_blocker_count, no leak of ref/title/slug.
  - TestOpenChildrenGuard_AllBlockersHiddenSurfaceGenericMessage —
    open_children=[], hidden_blocker_count>0, message mentions "you
    don't have access to."
  - TestOpenChildrenGuard_TOCTOURace — 8 iterations of a child-flip
    racing a parent-terminal update; asserts the forbidden outcome
    (parent=completed AND child=open) never occurs.
  - TestClassifyHTTPStatus_OpenChildrenPreservesCodeAndDetails +
    inverse generic-409 test.
  - TestClassifyExecError_OpenChildrenMarkerLiftsStructuredPayload +
    no-marker-falls-through inverse.

* fix(server): open-children guard round 3 — 7 Codex findings closed (IDEA-1494)

P1 — visibility fail-closed. The handler was swallowing
visibleCollectionIDs errors, leaving visIDs==nil which the guard
treats as unrestricted, leaking hidden-child metadata. Now surfaces
the error as 500 BEFORE installing the precheck. Test:
TestOpenChildrenGuard_VisibilityLookupErrorFailsClosed closes the
store DB and asserts no 409+children leak.

P1 — link mutations acquire the advisory lock. SetParentLink,
ClearParentLink, CreateItemLink (when link_type ∈ childLinkTypes via
new isChildLinkType helper), DeleteItemLink (same condition), and
RestoreItem now take `pad:parent-children:<id>` in canonical sorted
order via new AcquireParentChildrenLocks helper. SetParentLink locks
BOTH old and new parents (re-parenting case). Race test
TestOpenChildrenGuard_LinkMutationRace asserts the forbidden
"link-committed-before-parent-flip AND parent flip succeeded" never
occurs by comparing link.created_at to parent.updated_at. Documented
semantics: status-wins + link-after-commit is legal under the
invariant "no open children EXIST AT THE MOMENT of transition" —
the post-condition variant ("no open child may EVER attach to a
terminal parent") is intentionally deferred.

P1 — MoveItem bypass closed. New MoveItemWithPreCheck mirrors
UpdateItemWithPreCheck — acquires workspace seq lock + parent-children
locks, re-reads in tx, runs caller precheck. handleMoveItem builds
the same guard closure using the DESTINATION schema for done-field
resolution (conservative — honors the schema the item moves INTO).
CLI gains `pad item move --force`, client gains MoveItemWithForce
that appends `?force=true` to the move endpoint. MCP catalog +
mapItemMove forward `force` through the route mapper. Tests:
TestOpenChildrenGuard_MoveItem_RejectsTerminalWithOpenChildren and
…_ForceOverrides.

P2 — pre-tx field-read TOCTOU. UpdateItemWithPreCheck and
MoveItemWithPreCheck now re-read the item via new getItemTx INSIDE
the tx (after locks) and pass that fresh snapshot to the precheck
closure; the precheck classifies the transition against the in-tx
view, not the handler-side pre-tx capture. Handler precheck closure
swaps `currentFieldsJS` from the in-tx snapshot. Test:
TestOpenChildrenGuard_PrecheckReadsInTxSnapshot stages a between-load
status mutation and asserts the precheck observes the post-mutation
fields.

P2 — bulk-update carries structured errors. cmd/pad/main.go's
updateFailure struct extended with Code + Details
(json.RawMessage). When client.UpdateItem returns *cli.APIError, the
row preserves the structured envelope. Human-text output also
renders the open-children list inline. Chose JSON-envelope route
over per-row stderr markers because bulk-update already produces a
structured envelope and ExecDispatcher returns stdout verbatim on
exit-0 — no classifier change needed. Test:
TestBulkUpdateStructuredFailuresCarryOpenChildrenDetails confirms
the wire shape the CLI lifts.

P3 — marker hardening. Marker bumped to versioned form
`pad-structured-error/v1:` (was `pad-error:`). cli.StructuredErrorMarker
+ mcp.structuredErrorMarker kept in lockstep with cross-references.
mcp.allowedStructuredErrorCodes whitelists known codes (currently
just open_children); unknown codes fall back to regex classification.
Marker must start the line after whitespace trim (embedded markers
ignored). Last-marker-wins to defeat pre-emption attacks. Tests:
TestClassifyExecError_{UnknownStructuredCode,OldMarkerVersion,
MarkerEmbeddedMidLine,LastMarker}.

P3 — soft-deleted collection schemas honored. New GetCollectionAnyState
mirrors childrenDoneFiltersForParent's inclusion rule; guard uses it
so a child still attached to a soft-deleted collection is evaluated
against ITS schema (custom terminal_options) instead of the default-
status fallback (which would mis-classify and false-block). Test:
TestOpenChildrenGuard_SoftDeletedCollectionSchemaHonored seeds a
custom collection, soft-deletes it while a child remains, and
asserts the terminal status is correctly recognized.

Comprehensive store-mutation audit results recorded in the PR
description (every method touching items.fields / items.collection_id
or item_links).

* fix(server): open-children guard round 4 — multi-parent locks, enum parity, PATCH atomicity (IDEA-1494)

Four Codex round-3 (blast-radius lens) findings, each fixed with the
recommended shape.

P1 — multi-parent lock set. acquireParentChildrenLocksForUpdate and
RestoreItem previously used `LIMIT 1` against item_links, so a child
with BOTH a `parent` link to P1 AND an `implements` link to P2 only
locked one of them. The other parent's open-children precheck could
race against the child's status flip and miss it.

Fix: new listParentChildLockKeys helper runs the same query
GetChildItems' inclusion rule uses (childLinkTypes), returns ALL
distinct parent target_ids, and feeds them into the canonical
multi-lock helper. Both UpdateItemWithPreCheck and RestoreItem now
acquire locks on {self} ∪ {all-parents-via-childLinkTypes}. Test:
TestOpenChildrenGuard_MultiParentChildLocksAll races a child status
flip against terminal-updates on both parents simultaneously.

P2 — lock-order asymmetry. The pre-fix codebase had multiple lock-
acquisition shapes: parent-then-self in acquireParentChildrenLocksForUpdate,
single-key in RestoreItem / CreateItemLink / DeleteItemLink /
ClearParentLink, and a sorted multi-key in SetParentLink. Two
concurrent callers using different ad-hoc orderings could AB/BA
deadlock.

Fix: removed the per-call-site AcquireParentChildrenLock helper
entirely. Every site now goes through AcquireParentChildrenLocks
(the canonical sorted multi-lock helper) — including ones that need
only one ID (the variadic call still sorts a one-element slice).
The helper's doc comment explicitly states the contract: "Ad-hoc
single-key acquisition outside this helper is FORBIDDEN — two call
sites taking distinct keys in different orders WILL deadlock."
Test: TestOpenChildrenGuard_NoDeadlockUnderReverseOrderConcurrency
runs reverse-order re-parents with a 5-second timeout; assertion
fails on hang.

P2 — HTTP/stdio code-surface parity. Round 2's HTTP pass-through
("any non-conflict upstream code") silently widened the ErrorCode
enum beyond stdio's allow-list (`open_children` only). Agents saw
different code surfaces depending on which dispatcher delivered
the response.

Fix: HTTP 409 branch in classifyHTTPStatusKind now consults the
same allowedStructuredErrorCodes whitelist stdio does. Codes
outside the set collapse to ErrConflict (no details), matching
what stdio does for an unknown-code structured marker. Doc on
allowedStructuredErrorCodes updated to make the dual-consumer
contract explicit: "Adding a new structured code is a TWO-WAY
change." Tests:
TestClassifyHTTPStatus_UnknownConflictCodeFallsBackToErrConflict
and TestStructuredErrorCodeParityAcrossTransports.

P3 — PATCH atomicity. A combined PATCH with `parent` + `status=terminal`
on an item with open children used to commit the parent-link change
INLINE (before the guard ran) and then reject the field write.
Caller saw 409 but the parent had already moved.

Fix: parent-link mutation is now DEFERRED — captured into outer-
scope vars during fields validation, executed AFTER
UpdateItemWithPreCheck succeeds. A guard rejection returns before
the link write block, so on rejection the link is untouched.
Documented choice: "reorder, don't tx-wrap" — wrapping SetParentLink
into the same store tx would require threading a *sql.Tx through
the SetParentLink API (which is also called from the
handler_item_links path); reordering is the smaller surgery and
gives the correct outcome on the failure direction. A residual
window remains in the OTHER direction (field write commits, link
write fails) — not made worse by the reorder, and called out
inline for a future tx-wrap pass.

Test: TestOpenChildrenGuard_PatchAtomicRejectionPreservesParentLink
sets up target → oldParent → openChild, sends PATCH {parent=newParent,
status=completed}, asserts 409 AND target.parent_link still points
at oldParent.

xarmian 9ebdfb503e Revert "feat(cli): pad session shape — Claude Code context-window telemetry (IDEA-1491) (#569)" (#570)
This reverts commit 351f83af3f.

xarmian 351f83af3f feat(cli): pad session shape — Claude Code context-window telemetry (IDEA-1491) (#569)
* feat(cli): pad session shape — Claude Code context-window telemetry (IDEA-1491)

New `pad session shape [--session <id|path>] [--format json|table|markdown]`
command that reads the active Claude Code session JSONL and reports tokens,
context_pct (vs hardcoded per-agent-version budget), message counts, and
elapsed time. Default format is JSON because agents are the primary caller.

- internal/cli/claudecode.go: project-slug derivation, JSONL streaming
  parser, env/cwd/autodetect cascade resolver, per-version budget table
  (seeded with 2.1.* → 1M tokens per the IDEA-1491 recon update).
- cmd/pad/session.go: top-level `session` group + `shape` subcommand,
  three output formats, registered via cmd/pad/main.go's rootCmd.
- Tests cover slug derivation (live ~/.claude/projects/ verified cases),
  JSONL parse (normal / no-usage / sidechain fixtures), budget lookup,
  context-class bucketing, and the resolver cascade in t.TempDir().

Sidechain/sub-agent JSONL summing and the IDEA-body Pad-invocation-count
fallback are intentionally deferred to v2 (TODOs in session.go).

* fix(cli): session shape — TotalPrompt as context numerator + count parallel tool_use (IDEA-1491)

Codex R1 review findings:

P1 — context_pct numerator was CacheRead, which is a steady-state proxy
that under-counts at turn boundaries when fresh content sits in
cache_creation/input before being folded into the cached prefix. The
correct denominator-of-budget is the full prompt footprint sent this
turn: cache_read + cache_creation + input = TotalPrompt. Markdown
renderer's context-tokens line follows suit; the explicit per-component
breakdown rows keep CacheRead so the components remain visible.

P2 — ToolInvocations was counting assistant-turns-with-any-tool-use, not
tool invocations. A single assistant turn can emit multiple parallel
tool_use blocks in message.content[]; the field name promises a count
of invocations. Drop the early break.

Test fixture normal.jsonl gains a 3-parallel-tool-use final turn; assert
ToolInvocations==4 (up from 2) to pin the new behavior.

* fix(cli): session shape — path-traversal, oversized-line, content-variant, explicit-flag errors (IDEA-1491)

Codex R2 review findings:

P1 — session-ID inputs (--session flag-id branch AND
$CLAUDE_CODE_SESSION_ID env var) are now validated before they become
filename fragments under ~/.claude/projects/<slug>/. Reject path
separators, '..' segments, and anything that doesn't match a UUID-ish
shape (hex+dashes, 8+ chars). New ErrInvalidSessionID wraps a
descriptive message. Without this, `--session ../../../../../tmp/foo`
or a poisoned env var could escape the projects dir on the candidate
os.Stat. End-to-end smoke confirms `pad session shape --session
'../../../etc/passwd'` now errors with "invalid session id: ...
contains a path separator" and exits non-zero.

P2a — Switch the JSONL line reader from bufio.Scanner (8 MiB cap, hard
fail on overflow with "token too long") to bufio.Reader.ReadBytes('\n')
(no cap). encoding/json has no size limit either, so oversized records
— e.g. inline file attachments — parse cleanly. Both ParseSessionJSONL
and tailLineCWD updated for parity.

P2b — jsonlLine.Message.Content was []json.RawMessage at the outer
decode, which made a schema variant where content is a string or
object fail the WHOLE line's decode, losing type/timestamp/version/
usage data. Now Content is a raw json.RawMessage; the tool-use scan
re-decodes it as []json.RawMessage on a best-effort basis and skips
tool-counting when that fails, while preserving the rest of the line.

P3 — `pad session shape --session <id|path>` no longer silently falls
back when the resolver errors. An explicit flag means the caller has a
specific session in mind; a typo or wrong UUID should fail loudly so
automation surfaces the bug instead of emitting `agent: "unknown"`.
The implicit (no-flag) path still falls back for non-Claude-Code
harnesses.

Tests added/extended:
- TestResolveSessionLog_RejectsPathTraversal — flag-id AND env-id
  branches, full bad-input matrix.
- TestParseSessionJSONL_OversizedLine — 10 MiB single record.
- TestParseSessionJSONL_NonArrayContent — content-as-string variant
  must still contribute timestamp/version/usage.
- TestParseSessionJSONL_ParallelToolUse — tight hermetic check of the
  R1 P2 multi-tool-per-turn fix.
- TestBuildSessionShape_ExplicitFlagErrors — verify --session errors
  propagate.
- TestBuildSessionShape_ImplicitFallback — verify implicit path
  still falls back.

xarmian 4bbd0a210d feat(collections): widen LibraryPlaybook with InvocationSlug + Arguments (TASK-1398) (#527)
* feat(collections): widen LibraryPlaybook with InvocationSlug + Arguments (TASK-1398)

Adds two optional fields to LibraryPlaybook:
- InvocationSlug — kebab-case slug for `/pad <slug>` routing (PLAN-1377)
- Arguments — argument spec mirroring the body's `## Arguments` section

Both fields are tagged with `omitempty` so existing library entries
(none of which set them) serialize unchanged. seedPlaybookFromLibrary()
now forwards both into the seeded item's Fields JSON only when set,
matching the shape ShipPlaybook() already writes.

This is the foundational task that unblocks T2 through T6 of the
playbook library overhaul.

Parent: PLAN-1397.

* fix(library): propagate invocation_slug + arguments through activation paths per Codex review (round 1)

Codex round 1 caught that the activation paths for library playbooks
rebuild the fields map and drop the new fields, so any library entry
declaring invocation_slug/arguments would lose `/pad <slug>` routing
after activation.

Fixed in three places:
- internal/cli/client.go LibraryPlaybook (the client-side mirror used
  by the CLI `pad library activate` command)
- cmd/pad/main.go libraryActivate (CLI subprocess activation)
- internal/mcp/dispatch_http_slice4.go dispatchLibraryActivate (MCP
  pad_project action=library-activate)

All three now forward invocation_slug and arguments only when set,
matching ShipPlaybook()'s shape exactly.

Web client (web/src/lib/api/client.ts) activation payload is T2's
explicit scope — left for that PR.

xarmian fed4b60e65 feat(playbook): add pad playbook CLI (list/show/run) + endpoints (TASK-1382) (#520)
* feat(playbook): add pad playbook CLI (list/show/run) + endpoints (TASK-1382)

PLAN-1377 T5 — first-class invokable-procedure surface. Three HTTP
endpoints + three CLI subcommands, with a strict CLI arg parser and a
side-effect-free run path.

Endpoints

  GET  /workspaces/{ws}/playbooks         — metadata array, same
                                            projection as bootstrap
  GET  /workspaces/{ws}/playbooks/{ref}   — full item, resolved by
                                            invocation_slug | ref | slug
  POST /workspaces/{ws}/playbooks/{ref}/run — bind args, return body +
                                              bound + unbound. No
                                              execution; the agent
                                              owns step playback.

Resolution

  resolvePlaybook walks invocation_slug first (the /pad <slug>
  user-facing identifier), then falls back to ResolveItem (UUID / ref /
  slug). A stray TASK-5 hitting /playbooks/TASK-5 returns 404 instead
  of leaking a non-playbook into the surface.

Arg parsing

  ParsePlaybookCLIArgs implements the strict rules from PLAN-1377:
    - Required positional args first, in declared order.
    - Flag types: bareword presence sets true.
    - Other types: key=value form (number is parsed as float64,
      enum is validated against declared options).
  The server takes either pre-parsed args (MCP / programmatic callers)
  OR raw CLI tokens (CLI caller); merge logic prefers explicit args
  over raw_args. The CLI sends raw_args, so there is one parser
  implementation and no drift risk.

CLI

  pad playbook list                        — table or json
  pad playbook show <slug|ref> [--format]  — markdown / json
  pad playbook run <slug|ref> [args...]    — body + bound args

Client method

  cli.Client.{ListPlaybooks, ShowPlaybook, RunPlaybook(args,
  rawArgs)} — runtime callers pass args; CLI passes rawArgs.

Tests

  TestPlaybookList, TestPlaybookShowByInvocationSlug,
  TestPlaybookShowByRef, TestPlaybookShowRejectsNonPlaybook,
  TestPlaybookRunBindsArgs (with-args, missing-required, with-raw-args),
  TestParsePlaybookCLIArgsErrors, TestPlaybookListEmptyShape.

Parent: PLAN-1377.

* fix(playbook): tighten arg parsing per Codex round 1 (TASK-1382)

P2.1 — Positional binding now skips optional and flag-typed slots.
The PLAN-1377 contract says ONLY required args fill positional slots;
other typed args must be key=value. Without this, a spec with an
optional arg before a required one (e.g.
[merge-strategy?, target!]) bound the caller's bareword TASK-7 to
merge-strategy instead of target.

P2.2 — number coercion now uses strconv.ParseFloat with NaN/Inf
rejection. Sscanf(%g) was sloppy: it accepted '1abc' as 1 (partial
match) and accepted NaN/Inf, which json.Marshal then refused after
the handler had already written a 200 header.

P3 — empty-body run requests now decode cleanly. The decodeJSON
wrapper folds io.EOF into 'invalid JSON: EOF' so the previous
err.Error() != "EOF" check never fired. errors.Is(err, io.EOF) on
the unwrapped chain handles the wrapping correctly.

Tests: TestPlaybookRunAcceptsEmptyBody,
TestParsePlaybookCLIArgsOptionalNotPositional,
TestCoercePlaybookValueNumberRejectsBadInput.

xarmian 24f0445efa feat(bootstrap): single-roundtrip /pad context-load endpoint (TASK-1379) (#518)
* feat(bootstrap): single-roundtrip /pad context-load endpoint (TASK-1379)

Implements the agent bootstrap surface for PLAN-1377. One HTTP call
replaces the four separate /pad context-loading invocations (workspace
+ collections + conventions + roles + playbooks) the skill used to
make, cutting ~200-400ms of startup latency on every /pad command.

Wire shape:

- GET /api/v1/workspaces/{ws}/agent/bootstrap returns AgentBootstrap:
  workspace { slug, name, id }, user { name, email, id },
  collections [...], conventions [...always-on, status=active],
  roles [...], playbooks [metadata-only — no bodies], dashboard {...},
  recent_activity [... 24h].
- pad bootstrap [--format json|markdown] CLI wrapper. JSON is the
  canonical wire format that the /pad skill consumes; markdown is a
  human-readable summary for quick terminal inspection.

Implementation notes:

- Single source of truth: Server.BuildAgentBootstrap. The HTTP handler
  is a thin wrapper, and TASK-1380 will reuse it from three MCP
  surfaces (resource + set_workspace embed + pad_meta tool action).
- Dashboard reuse: handleGetDashboard's body extracted into
  buildDashboardResponse(workspaceID, r) returning (*DashboardResponse,
  error). The HTTP handler is now a thin wrapper; bootstrap calls the
  builder directly to embed dashboard data without a second roundtrip.
- Playbook bodies are deliberately NOT included — metadata only
  (~80 bytes/entry vs 5-10KB) so the bootstrap stays small for
  workspaces with many playbooks. Full bodies load on invocation.
- Convention bodies ARE included for the always-on/active subset (must
  be agent-known up front); trigger-specific conventions stay
  load-on-demand.
- Empty slices serialize as [] not null so the agent doesn't need
  defensive nil checks.

Tests:

- TestBootstrapEmptyWorkspace, TestBootstrapEmptyArraysNotNull,
  TestBootstrapIncludesPlaybookMetadata,
  TestPlaybookSummaryPrefersFirstParagraph.

Parent: PLAN-1377.

* fix(bootstrap): respect collection visibility + guest grants (TASK-1379)

Codex round 1: BuildAgentBootstrap was bypassing visibility filters,
so a guest admitted by RequireWorkspaceAccess could read collections,
conventions, and playbook metadata they don't have access to.

Now mirrors handleListCollections + handleGetDashboard:

1. Resolve visibleCollectionIDs(r, workspaceID) once.
2. Filter the Collections array through isCollectionVisible.
3. Gate the conventions + playbooks sub-queries on whether the caller
   can see those collections at all (presence in the filtered slice
   implies visibility).
4. Empty slices for inaccessible sub-resources, so the wire shape
   stays consistent — no missing keys to confuse the agent skill.
5. Pass-r=nil callers (future MCP in-process dispatchers) keep the
   'full visibility' shortcut, but the doc comment now spells out that
   those callers MUST verify access out-of-band.

Parent: PLAN-1377.

* fix(bootstrap): apply guest item-level grants + recompute role counts (TASK-1379)

Codex round 2:

P1 — Item-level guest grants now flow into the convention + playbook
sub-queries. visibleCollectionIDs alone admits the conventions /
playbooks collection if a guest has ANY item grant inside it; without
ItemIDs filtering, those queries then return the whole always-on
convention body set or every playbook's metadata. Now mirrors the
handleListItems shape: resolve (fullCollIDs, grantedItemIDs) via
guestResourceFilter, and pass the (collIDs, itemIDs) tuple through to
collectAlwaysOnConventions + collectPlaybookMetadata so a guest with a
single grant only sees that one item.

P2 — AgentRole.ItemCount is now recomputed from the visible item set
for restricted callers, matching handleListAgentRoles. Without this,
a guest could read role counts computed across all workspace items and
infer hidden activity per role.

Helper signatures updated to accept (collIDs, itemIDs); the doc
comments explain the nil/non-nil semantics so future callers can't
silently regress this.

Parent: PLAN-1377.

* fix(bootstrap): rewrite collection counts from visible set for guests (TASK-1379)

Codex round 3: Collection.item_count + active_item_count are computed
across the whole collection by ListCollections, so a guest with one
item grant in a collection still received the collection in the
filtered list but with hidden counts. Reuse the visible item set
(already computed for role counts) to recompute collection item_count
for restricted callers. active_item_count is set equal to item_count
to avoid a separate done-rules buildup the bootstrap consumers don't
depend on — better a self-consistent number than a leaked one.

      "http://127.0.0.1:7777":   {"token": "...", "user_id": "...", ...}
    }
  }

v1 (legacy, read-only): {"server_url": "...", "token": "...", "user_id": "...", ...}

Reads transparently migrate v1 → v2 in memory; writes always emit v2.
Side-effect-free reads — the on-disk file stays v1 until login/logout/
setup triggers a Save, which is when migration becomes durable. This
keeps `pad <read-only-command>` from rewriting credentials.json on
every invocation just because the binary upgraded.

## API

Replaces the three top-level helpers (LoadCredentials / SaveCredentials /
DeleteCredentials) with a CredentialStore type:

  - LoadStore() (*CredentialStore, error)
  - (s).Get(serverURL) *Credentials       // nil-receiver safe
  - (s).Set(serverURL, *Credentials)
  - (s).Delete(serverURL)
  - (s).Save() error
  - WipeCredentialsFile() error           // file-level — replaces DeleteCredentials

URL canonicalization is built in: trailing slash + surrounding whitespace
are stripped before lookup/store, so http://x:7777 and http://x:7777/
hit the same bucket. Same rule cmd/pad/server_info.go was already
applying via its now-redundant normalizeURL — removed.

No top-level `default` field. The configured server (cfg.BaseURL() from
~/.pad/config.toml or --url) is always the source of truth for "which
server am I targeting" — a separate `default` would create a second
source of truth and the split-brain bugs that follow.

## Behavioral changes

- `pad init --url <other>` against a server you've authed to before now
  reuses the saved credential instead of clobbering it.
- `pad auth logout` removes only the configured server's entry. Other
  servers' tokens stay intact (pre-fix: wiped the whole file).
- `pad auth whoami` reads only the entry matching the configured server.
- Single-server users see no behavior change — one entry, identical
  shape per entry, identical UX.

## Compat shims removed

LoadCredentials / SaveCredentials / DeleteCredentials are deleted
outright (no // Deprecated lifecycle) — they're internal package
helpers with no external API contract. All 10 call sites in cmd/pad/
and internal/cli/ are migrated to the per-server API in this PR.

## Tests

internal/cli/credentials_test.go (15 tests):
- File missing / empty → empty store (callers don't need nil checks)
- v1 format reads + migrates in memory
- v1 with empty token → empty store (no phantom entries)
- v1 migration is durable on first Save (file flips to v2)
- v2 round-trip preserves multiple entries
- Set adds + replaces; mirrors URL into ServerURL field
- Delete keeps siblings (multi-server keystone behavior)
- Delete on absent key is a no-op
- Nil receiver Get/Delete don't panic (NewClientFromURL relies on this)
- URL normalization (trailing slash + whitespace)
- Save preserves all entries across the file boundary
- Save uses 0600 permissions
- WipeCredentialsFile removes the file + is idempotent
- Garbage file errors loudly (so we never silently lose data)

Existing tests unchanged. Full suite + lint + web-check green.

xarmian 51959532ad feat(auth): browser-based pad auth setup via /setup#token deep link (TASK-1216) (#432)
* feat(auth): browser-based pad auth setup via /setup#token deep link (TASK-1216)

`pad auth setup` now hands the operator a deep link into the browser-based
/setup form by default, replacing the in-terminal email/name/password
prompts. The browser flow gives them password-manager support, HTML5
email validation, and the live strength meter at zero CLI cost — the
mechanism (logs-token bootstrap, /setup route, /api/v1/auth/session) was
already shipped by TASK-1167 / PLAN-1166 for the Unraid use case. This
just unifies the local-CLI install path onto the same flow.

New `internal/cli/bootstrap.go::RunBrowserBootstrap`:
  - Reads <DataDir>/.bootstrap-token and prints
    `<BrowserURL>/setup#token=<TOKEN>` with the token in the URL fragment
    (not query) — fragments are scrubbed from the address bar by /setup's
    onMount before paint, so the secret doesn't survive in browser
    history (TASK-1167 F10).
  - Polls /api/v1/auth/session every 2s; returns nil when
    setup_required: false. Internal 5-min timeout uses a separate timer
    (not context.WithTimeout) so caller-ctx cancellation surfaces as
    ctx.Err() instead of being misreported as the helper's own timeout.
  - Idempotent: returns early if setup is already done, without touching
    the token file.
  - Dispatches on session.setup_method — "logs_token" reads the token,
    "open" (PAD_BYPASS_SETUP_TOKEN=true) prints a bare /setup URL,
    "local_cli" / unknown returns an error directing the user to
    --cli-prompt.

`pad auth setup` is rewired to call the helper, then chain doBrowserLogin
so the user ends up authenticated on the CLI — preserving the post-
condition of the legacy --cli-prompt path. Two browser approvals (admin
creation, CLI auth) but each is one click in a browser the operator
already has open.

The legacy TTY path lives on behind --cli-prompt as a zero-cost hedge
per IDEA-1179. Existing promptAndBootstrap / readPassword helpers are
left in place — TASK-1217 will audit whether they can be removed once
pad init is on the new flow too.

Tests in internal/cli/bootstrap_test.go cover: idempotent session check,
logs_token happy path, open mode, missing/empty token error paths,
local_cli + unknown method rejection, internal timeout firing with the
friendly message, caller-ctx cancellation propagating ctx.Err() (not
timeout error). bootstrapPollInterval / bootstrapPollTimeout are vars so
the timeout-branch test can run in 100ms instead of 5min.

Implements: IDEA-1179 (auth-setup half).
Out of scope: pad init integration → TASK-1217.
Out of scope: post-/setup workspace dead-end → IDEA-1215.

* docs(cli): clarify RunBrowserBootstrap caller staging across TASK-1216 / TASK-1217

Codex review (round 1) read the docstring and flagged that `pad init`
isn't on the new helper. That wiring is TASK-1217's scope by design (one
task = one PR per CONVE-2; TASK-1217 has a hard blocked-by link to
TASK-1216). Tighten the docstring to make the staging explicit so a
reader of the diff alone doesn't conclude it's a missing wire-up.

xarmian 5e27989ab8 feat(attachment): add pad attachment view|show|list CLI surfaces (IDEA-898) (#321)
* feat(attachment): add `pad attachment view|show|list` CLI surfaces (IDEA-898)

Agents and CLI users had no first-class way to fetch attachment bytes
through the API: the only path to read an `![alt](pad-attachment:<uuid>)`
reference was to read the raw blob out of `~/.pad/attachments/<storage_key>`,
which bypasses workspace ACLs, doesn't work on Pad Cloud / remote /
Postgres deployments, skips the variant pipeline (TASK-872 / TASK-879 /
TASK-880), and breaks when storage moves to S3.

Three new subcommands wrap the existing REST endpoints:

- `pad attachment view <id> [-o path]` — agent-friendly: with no `-o`,
  fetches to a fresh OS temp directory using the stored filename and
  prints just the absolute path on stdout (so `$(pad attachment view <id>)`
  composes cleanly into shell pipelines). Reuses `download`'s atomic
  temp-then-rename pattern via a shared helper.

- `pad attachment show <id>` — HEAD-based metadata only; surfaces MIME,
  size, filename, ETag, Last-Modified.

- `pad attachment list [--item REF] [--category X] [--attached|--unattached]
  [--collection ID] [--sort ...] [--limit N] [--offset N]` — workspace
  list. The `--item REF` flag resolves a TASK-5-style ref to a UUID
  client-side and passes it to a new `item_id` query param on the list
  endpoint (server side: AttachmentListFilters.ItemID, ~6 lines in the
  store + 1 in the handler).

Skill update: `skills/pad/SKILL.md` gains a "Working with attachments"
subsection plus a CLI Reference entry, both ending in the hard rule that
agents must NEVER read directly from `~/.pad/attachments/`.

* style(cli): gofmt AttachmentListParams field alignment

CI's golangci-lint v2 flagged this with the gofmt formatter (configured
with simplify: true in .golangci.yml). The contiguous Sort/Limit/Offset
block at the end of the struct needs uniform column alignment — gofmt
considers the doc comment above Sort attached to that field rather than
a block separator, so the three int/string fields get aligned together.

Verified locally with `golangci-lint run --timeout=5m ./...` (v2.11.4 to
match CI) — 0 issues. Local make lint only runs `go vet ./...` and
`golangci-lint` wasn't installed, which is why this slipped through;
filing a separate follow-up to mirror the CI checks in the local
workflow.

xarmian 134f55045d feat(attachments): import workspace bundle with rehydrate + UUID remap (TASK-885) (#306)
* feat(attachments): import workspace bundle with attachment rehydrate + UUID remap (TASK-885)

POST /workspaces/import now accepts a tar.gz bundle (Content-Type:
application/gzip) and rebuilds the workspace + attachments + items in
one round trip. JSON imports still work — content-type dispatch in
handleImportWorkspace routes the request.

Three-phase flow:
1. Walk the tar, capture pad-export.json + manifest.json + every
   attachment blob into memory.
2. Run the existing ImportWorkspace path to create the workspace +
   collections + items + comments + links + versions. New IDs are
   generated; item.slug is preserved (the existing remap path
   doesn't re-slugify).
3. For each manifest entry, rehydrate the blob through the storage
   backend (re-validate MIME + re-hash defensively, don't trust the
   manifest), insert a fresh attachments row. Build an oldID→newID
   map keyed on attachment uuid.
4. Walk every imported item's content + fields, replace
   "pad-attachment:OLD" with "pad-attachment:NEW" in one
   transactional pass. Refresh FTS afterward (direct UPDATE bypasses
   triggers).

Phase 2 errors per-attachment are logged and skipped — the workspace
keeps importing rather than rolling back. The import handler returns
the new workspace and the operator can inspect logs for any
attachment that didn't make it.

CLI:
- pad workspace export now defaults to --bundle (.tar.gz) since
  pad import handles bundles. --json reverts to legacy items-only.
- pad import auto-detects format by file extension (.tar.gz / .tgz
  → application/gzip). Other extensions go through the legacy JSON
  path.
- New Client.PostRawWithContentType for explicit-content-type POSTs.

Tests:
- TestImportBundle_RoundTrip: upload → embed in markdown → export
  source → import to FRESH server → verify attachment list has 1
  row with new UUID → item content rewritten to new UUID and old
  UUID is gone → download new blob matches original bytes.
- TestImportBundle_LegacyJSONStillWorks: JSON content-type still
  hits the legacy path.
- TestImportBundle_RejectsBadGzip: garbage gzip body returns 400.

Parent: PLAN-866. With TASK-884 + TASK-885 merged, the round-trip
acceptance criterion (export → import → images intact) is met.

* fix(attachments): stream import end-to-end per Codex (round 1)

Two memory regressions Codex caught on PR #306:

P1 (server). importBundle was buffering every blob into a
map[string][]byte during a first pass, then iterating the manifest
on a second pass. A 2 GiB bundle full of 25 MiB attachments would
pin ~2 GiB of heap. Reworked to single-pass streaming:

  pad-export.json → import workspace + build slug→id map
  attachments/manifest.json → index entries by tar path
  attachments/<uuid>.<ext> → look up entry, rehydrate now

The export bundler always writes pad-export.json + manifest.json
BEFORE any blob (deterministic order from
handlers_export_bundle.go), so this works without buffering. Bundles
that violate the ordering — a third-party tool that writes blobs
first — return 400 with a clear error. Memory footprint now bounded
by the largest single blob (≤25 MiB) regardless of bundle size.

Stale blobs without a manifest entry are skipped (their bytes
io.Copy'd to io.Discard so the tar reader stays in sync). Unknown
top-level entries (forward-compat for future bundle additions) are
also consumed and ignored rather than left dangling.

P2 (CLI). pad import used os.ReadFile, buffering the entire bundle
client-side before posting. Switched to os.Open + a new
Client.PostStreamWithContentType helper that streams the body
directly into the request — together with the server-side fix,
import is end-to-end streaming.

Tests:
- TestImportBundle_RejectsOutOfOrderTar: hand-crafted bundle with
  a blob before pad-export.json returns 400 with "ordering" in
  the message.
- existing TestImportBundle_RoundTrip / LegacyJSONStillWorks /
  RejectsBadGzip continue to pass under the new streaming flow.

* fix(cli): give streaming endpoints a 1h timeout per Codex (round 2)

Codex P1 round 2: PostStreamWithContentType + RawStream were both
using the shared 10s-timeout httpClient. The default works fine for
normal API calls but kills a multi-GiB bundle import or export over
anything slower than a local network — Client.Timeout fires
mid-stream with "Client.Timeout exceeded".

Added a dedicated streamClient on Client with a 1h timeout, used by
both RawStream (export bundle download) and
PostStreamWithContentType (import bundle upload). 1h is generous
enough for ~100 MB/s uplinks shipping a 350 GiB bundle and still
caps a hung connection eventually.

The 10s default stays in place for every other call — short timeouts
are the right SLA for normal API requests and protect the CLI from
hanging on a wedged server.

* fix(attachments): make import bundle cap configurable per Codex (round 3)

Codex P1: the 2 GiB import cap was hard-coded with a comment promising
operator override "later" — but no setter existed, so workspaces over
2 GiB stream out fine on export and fail on re-import.

Added Server.SetImportBundleMaxBytes wired from the
PAD_IMPORT_BUNDLE_MAX_BYTES env var in cmd/pad/main.go. Mirrors the
existing PAD_ATTACHMENT_MAX_BYTES pattern. Default stays at 2 GiB so
the typical workspace works without configuration; operators with
larger exports can raise it without recompiling.

The per-blob cap (importBlobMaxBytes = 25 MiB) is intentionally kept
constant — it bounds in-flight memory regardless of total bundle
size, and a 25 MiB-per-blob ceiling matches the upload handler's
default, so a bundle can never smuggle larger blobs than the upload
endpoint accepts.

* fix(attachments): scale per-blob import cap with PAD_ATTACHMENT_MAX_BYTES per Codex (round 4)

Codex P1 round 4: importBlobMaxBytes was hard-coded at 25 MiB but
the upload handler's per-file cap is configurable via
PAD_ATTACHMENT_MAX_BYTES. An operator who raised the upload cap to
allow 50 MiB attachments could export a workspace successfully
(WorkspaceAttachmentsForExport doesn't gate on size) but the
re-import would reject every blob over 25 MiB.

Replaced the const with effectiveBlobMaxBytes() which reads
s.attachmentMaxBytes (or falls back to defaultAttachmentMaxBytes).
The pad-export.json cap also scales with this value (4×) so a
content-heavy workspace doesn't trip its own JSON ceiling on a
server with raised attachment limits.

Error message on a too-large blob now points the operator at
PAD_ATTACHMENT_MAX_BYTES so they know which knob to turn rather
than digging through code to find the cap.

* fix(attachments): independent metadata cap for bundle import per Codex (round 5)

Codex P2 round 5: tying pad-export.json + manifest.json caps to
PAD_ATTACHMENT_MAX_BYTES regressed deployments that LOWER the
attachment cap. A 1 MiB attachment cap would force metadata to fit
in 4 MiB / 1 MiB respectively — but metadata size scales with
workspace item count, not attachment blob sizes, so a tight upload
limit shouldn't gate it.

Added importMetadataMaxBytes = 100 MiB constant for both metadata
files. effectiveBlobMaxBytes() still drives the per-blob cap which
genuinely tracks attachment-upload policy.

xarmian a0336e0248 feat(attachments): bundle attachments + manifest in workspace export (TASK-884) (#305)
* feat(attachments): bundle attachments + manifest in workspace export (TASK-884)

GET /workspaces/{ws}/export?format=tar streams a gzip'd tar bundle:

  pad-export.json              # the existing WorkspaceExport JSON
  attachments/manifest.json    # uuid → {filename, mime, size, hash, ...}
  attachments/<uuid>.<ext>     # original blobs only — no thumbnails

Default (no ?format) keeps returning JSON so existing automation
hitting the endpoint without a query param continues to work
unchanged. The CLI's pad workspace export now opts into the bundle
by default; pass --json for the legacy items-only output.

Implementation:
- store.WorkspaceAttachmentsForExport returns originals only
  (parent_id IS NULL); thumbnails are re-derived on import via the
  existing pipeline so shipping them would double the bundle size.
- handleExportWorkspaceBundle streams chunks straight into the
  response writer rather than buffering — a workspace with multi-
  GB of attachments would otherwise pin that much memory.
- AttachmentManifest is versioned (separate from WorkspaceExport
  version) so the bundle layout can evolve independently.
- bundleAttachmentPath is exported (lowercase package fn) so the
  import path in TASK-885 can resolve manifest entries to tar
  entries without duplicating the filename logic.
- CLI gates against writing binary tar.gz to a TTY and appends the
  conventional extension when -o is passed without one.

Tests:
- TestExportBundle_RoundTrip: two uploads → bundle contains
  pad-export.json + manifest + 2 blobs whose bytes match the
  uploads + manifest decodes cleanly + WorkspaceExport decodes.
- TestExportBundle_HidesThumbnails: synthetic thumbnail row, the
  manifest excludes it.
- TestExportBundle_LegacyJSONStillWorks: no ?format param returns
  application/json with a decodable WorkspaceExport (backward
  compat regression guard).

Parent: PLAN-866. TASK-885 (import path + UUID remap) consumes the
manifest produced here.

* fix(attachments): stream export bundle + revert default to JSON per Codex (round 1)

Two findings from Codex on PR #305:

1. CLI buffered the entire response in memory via RawGet → io.ReadAll,
   defeating the server-side streaming design and risking OOM on a
   multi-GB bundle. Added Client.RawStream which copies the response
   body straight into an io.Writer; export now opens the target file
   and streams directly into it.

2. Default tar.gz output broke `pad export → pad import` round trip
   because the import handler still only accepts JSON. Reverted the
   CLI default to JSON; bundle is now opt-in via --bundle. The flag
   docstring notes that TASK-885 will flip the default once import
   handles bundles.

* fix(attachments): surface tar/gzip close errors and truncation per Codex (round 2)

Codex round 2 finding: deferred tw.Close() / gzw.Close() ignored
errors. If a backend returned fewer bytes than size_bytes claimed,
io.Copy returned nil, the tar writer's "missed N bytes" trip fired
at Close, and the handler still completed a 200 OK with a corrupt
bundle that gunzip would later refuse to decompress — silently from
the operator's perspective.

Two changes:
1. The deferred close now logs both tw.Close() and gzw.Close()
   errors with structured context, so a corruption-on-finalize
   trip shows up in the operator log.
2. streamAttachmentToTar checks the bytes-copied count against
   a.SizeBytes after io.Copy and returns a per-attachment error
   when they disagree. The error is logged with attachment_id +
   storage_key so an operator can correlate the corruption with
   the row to investigate.

Regression test: TestExportBundle_TruncatedBlobLogsError forces a
size_bytes/blob desync via direct UPDATE and asserts the resulting
bundle bytes don't decode cleanly. (HTTP status stays 200 because
headers are already on the wire by the time we detect the desync;
that's an inherent limitation of mid-stream errors, but the new
logs + close-error surfacing make the failure observable.)

* fix(attachments): X-Bundle-Status trailer for export-stream success per Codex (round 3)

Codex P1 round 3: even with the per-blob truncation log + tar/gzip
close-error logs, mid-stream failures looked successful to clients.
The CLI's RawStream finished without a transport error, the file
landed on disk, and "Exported workspace" printed regardless of
whether the bundle was actually complete.

Two complementary signals now mark a clean stream:

1. HTTP trailer X-Bundle-Status. The handler declares the trailer
   in the initial Trailer header and sets it to "ok" only after
   tw.Close() and gzw.Close() both return without error. CLI checks
   the trailer after streaming and discards the file + returns
   error if it's absent or non-"ok".

2. The handler skips the deferred clean close on the error path,
   leaving the gzip footer unwritten. A client that ignores the
   trailer (curl, third-party tooling) still sees a corrupt gzip
   stream that gunzip refuses to decompress.

CLI: pad workspace export --bundle now removes any partial output
file on failure rather than leaving a corrupt one behind.
Client.RawStream signature changed to return (bytes, *http.Response,
error) so callers can inspect resp.Trailer; the only caller is the
export command.

Tests: TestExportBundle_TruncatedBlobAbortsStream now asserts both
signals (trailer absent + gzip/tar can't fully decode), and
TestExportBundle_SuccessTrailer pins the happy-path trailer.

xarmian fc1c47f124 feat(attachments): CLI + TypeScript clients + types (TASK-873) (#290)
* feat(attachments): CLI + TypeScript clients + types (TASK-873)

Rounds out the API surface with Go and TS client methods + a
\`pad attachment\` Cobra subcommand for ops debugging.

internal/cli/client.go
  AttachmentUploadResult struct mirrors POST /attachments JSON.
  UploadAttachment streams a multipart file part via io.Pipe — never
  buffers the upload in memory. itemRef is optional. Uses a fresh
  http.Client with a 5-minute timeout per request so a 25 MiB upload
  over a constrained link doesn't trip the package-shared 10s default.
  DownloadAttachment streams the bytes into the caller's writer,
  returning Content-Type + total bytes copied. Optional ?variant=
  parameter for thumbnails (server falls back to original silently
  per TASK-872).

cmd/pad/main.go
  pad attachment upload <item-ref|-> <path> [--filename NAME]
  pad attachment download <id> <out|-> [--variant thumb-sm|thumb-md]

  Item arg accepts an issue ref (TASK-5) or slug; "-" means no parent.
  Out arg "-" streams to stdout (with status messages on stderr) so
  callers can pipe into image viewers etc. Resolves the item via
  GetItem first so a typo'd ref fails fast with a useful error.

  List + delete subcommands intentionally omitted — those endpoints
  ship with TASK-881 (storage usage) and the future GC task. Adding
  client methods that hit 404s would mislead callers; same logic kept
  the upload response's "url" out of TASK-871 until TASK-872 wired GET.

  AttachmentUploadResult interface for the upload response shape.

web/src/lib/api/client.ts
  api.attachments.upload(workspaceSlug, file, itemId?) — multipart
  POST via direct fetch (skips shared request() because that helper
  hard-codes Content-Type: application/json). Carries CSRF, cookies,
  and the same 401 → /login redirect.
  api.attachments.downloadUrl(workspaceSlug, attachmentId, variant?)
  is a pure URL builder so callers can wire <img src> directly without
  going through fetch.

* fix(cli): atomic download — write to temp + rename so a failed download doesn't truncate the destination per Codex review (round 1)

P2: pad attachment download <bad-id> /existing/file used to wipe the
existing file on auth/network/404 errors because os.Create truncated
before the request was even attempted. The bytes were never written
because DownloadAttachment errored out, but the destination was
already 0 bytes — a footgun for anyone running the CLI in scripts.

Fix: for the file-path case, write to a sibling .tmp via os.CreateTemp
in the destination directory, fsync, close, then os.Rename only on
success. Same atomic-write pattern as FSStore.Put. The defer cleans
up the .tmp on any error path.

The stdout case (outPath == "-") is unchanged — bytes already
streamed to stdout can't be rolled back, so any partial write is
just visible to the caller as a short payload.

Verified end-to-end:
  echo X > /tmp/existing.png
  pad attachment download not-a-real-id /tmp/existing.png  # errors
  cat /tmp/existing.png   # still "X" — file untouched

* docs(cli): clarify os.Rename atomic-replace behavior on Windows (Codex round 2 disagreement)

Round 2 flagged this as P2: "os.Rename does not replace an existing
destination on Windows." That is technically incorrect for modern Go.

Verified directly against the Go stdlib source:

  src/internal/syscall/windows/syscall_windows.go:
    func Rename(oldpath, newpath string) error {
      ...
      return MoveFileEx(from, to, MOVEFILE_REPLACE_EXISTING)
    }

MoveFileEx with MOVEFILE_REPLACE_EXISTING atomically replaces an
existing destination on Windows. This has been the behavior since
Go 1.5 (2015), so every version of Go this codebase supports already
gets the desired replace-on-rename semantics on every platform.

Added an inline code comment so future readers don't worry about the
same false alarm. No code-path change.

xarmian 0fd5d0cdfb fix: green up Go (PostgreSQL) CI (BUG-842) (#275)
* fix(store): swap plainto_tsquery → websearch_to_tsquery for PG FTS (BUG-842)

`TestListItems_FTS_HyphenatedSearchTerm/task-five` has been failing on
every Go (PostgreSQL) CI run because `plainto_tsquery('english',
'task-five')` doesn't match the asciihword lexeme(s) the english parser
produces for an indexed `task-five-distinctive`. The result is that
every PG full-text search for hyphenated terms returns zero rows.

`websearch_to_tsquery` (Postgres 11+) is purpose-built for arbitrary
user input and tokenizes hyphenated terms the same way `to_tsvector`
does for the indexed document, so the query intersects the index
correctly. Swapped in three spots in the postgres dialect — FTSMatch,
FTSSnippet, FTSRank — and updated the caller-side comments that
referenced plainto_tsquery. SQLite path is unchanged: it goes through
items_fts MATCH with sanitizeFTSQuery, never through these methods.

* fix(server): drain background goroutines on Stop() (BUG-842)

`TestAdminBillingStats_SidecarSidecarError_DegradesToLocalOnly` (and
other server tests) have been flaking on the Go (PostgreSQL) CI runner
with `TempDir RemoveAll cleanup: directory not empty`. Root cause:
several request handlers spawned bare `go func() { ... }()` goroutines
that touched the SQLite WAL DB after the test function returned.
testServer's t.Cleanup closed the store but had no way to drain those
goroutines first, so a fire-and-forget WAL write could re-create the
`-wal`/`-shm` files between Close() and t.TempDir's RemoveAll.

Add a Server.bg sync.WaitGroup, a Server.goAsync helper that wraps a
WaitGroup-tracked goroutine, and a Server.Stop() that blocks until
every goAsync closure has finished. Convert the four known
fire-and-forget sites to goAsync:

- middleware_auth.go (TouchUserActivity)
- handlers_auth.go   (password reset email)
- handlers_cloud.go  (stripe_processed_events pruning)
- handlers_members.go (workspace invitation email)

Wire `srv.Stop()` into both testServer (server_test.go) and
newMetricsTestServer (metrics_auth_test.go) so cleanup order is

* fix(store): correct PG FTS hyphenation via OR-combined plainto_tsquery (BUG-842)

The previous attempt swapped plainto_tsquery → websearch_to_tsquery,
which was wrong: websearch_to_tsquery treats `-` as a NEGATION operator
(Google-style), so `task-five` becomes `task & !five` and the search
returns 0 rows for the same reason as before. This commit reverts the
swap and applies the actual fix.

PG's english parser indexes `task-five-distinctive` as
`{task-five-distinct, task, five, distinct}` — the asciihword AND its
parts. plainto_tsquery applied to the partial query `task-five`
produces `task-fiv & task & five`: the stemmed asciihword for the
PARTIAL query (`task-fiv`) is NOT in the vector, so the AND fails.

Replacing the hyphen with a space makes plainto emit `task & five`,
which DOES match — but doing that unconditionally breaks `BUG-842`-
style queries: PG indexes the `-842` suffix as a negative-number
lexeme, so `plainto_tsquery('BUG-842')` matches via `-842`, while
`plainto_tsquery('BUG 842')` searches for `842` and misses.

The fix ORs the two query variants together so the search vector is
matched against either the raw user query OR its hyphen-as-space form.
Both `task-five` (against `task-five-distinctive`) and `BUG-842`
(against `BUG-842 fix the cleanup race`) hit. Verified locally against
postgres:17-alpine via PAD_TEST_POSTGRES_URL — both 10x stress and
race-detector runs are green.

Surfaces:
  - dialect.go: FTSMatch / FTSSnippet / FTSRank now consume TWO
    placeholders each in the PG dialect.
  - items.go: listItemsFTS PG branch + SearchItems PG branch update
    args to pass (raw, sanitized) for every PG `?` placeholder.
  - search.go: SearchItems main / count / facets PG branches updated
    likewise. New sanitizePGFTSQuery helper alongside sanitizeFTSQuery.
  - documents.go: ListDocuments PG branch updated.

Tests:
  - TestListItems_FTS_HyphenatedSearchTerm extended with a `BUG-842`
    case to pin the OR-combined logic — naive hyphen-stripping would
    silently regress this.
  - New TestSanitizePGFTSQuery unit test.

* chore: gofmt 11 files with import-order issues (BUG-842 PR cleanup)

The Go (SQLite) CI job has been failing on `main` (and every PR built
against it) because golangci-lint flags 11 files whose third-party
imports are intermixed with internal imports — the import-grouping
rule that gofmt enforces. None of these were introduced by the
BUG-842 PR; they're pre-existing on main. The PR can't go green
without this cleanup, though, so it's bundled here.

Pure mechanical change — `gofmt -w <files>` only re-orders import
groups; no logic changes. Files touched:

  cmd/pad/configure.go
  cmd/pad/main.go
  internal/cli/format.go
  internal/server/handlers_admin_invitations.go
  internal/server/handlers_admin_users.go
  internal/server/handlers_grants.go
  internal/server/handlers_share_links.go
  internal/server/handlers_stars.go
  internal/server/middleware_auth.go
  internal/store/store.go
  internal/store/store_test.go

After this commit `gofmt -l ./cmd ./internal` returns clean.
