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).

David Barkhausen 03d73478ed fix(store): allow NULL api_tokens.workspace_id on SQLite for account tokens (#732)
Rebuild api_tokens on SQLite with workspace_id nullable, matching Postgres and the Go contract. Fixes the 500 on POST /api/v1/auth/tokens (workspace-agnostic account-token creation) on SQLite deployments.

Fixes #731.

xarmian 33e49434ed fix(server): non-fatal UA session binding + sliding session renewal (#727)
Two root causes behind users being logged out:

- UA session binding was unconditional and fatal — any User-Agent change
  (browser/WebView update, DevTools device emulation, mobile rebuild)
  silently de-authenticated the session. Now log-only across all three
  enforcement sites (TokenAuth, SessionAuth, and the validateSessionCookie
  helper used by CLI-auth/account/session-check routes), mirroring the
  default IP-change handling. (BUG-1815)

- Sessions had a fixed absolute TTL with no refresh on activity, so even an
  active user hit the cliff at 7d (web) / 30d (CLI). Adds sliding renewal:
  RenewSessionIfStale extends expires_at when past the half-window threshold,
  capped at created_at + 90d (SessionMaxLifetime), CAS-guarded and only
  reported when RowsAffected confirms the write. The middleware re-issues the
  session + CSRF cookies on renewal. New renew_ttl_seconds column (sqlite +
  pg migrations); legacy rows (0) keep their fixed expiry. (TASK-1816)

Reviewed by Codex (clean). Tests: store + server suites pass.

xarmian 3c3016abd9 feat(server): focused neighborhood mode on workspace graph endpoint (TASK-1781) (#718)
* feat(server): focused neighborhood mode on workspace graph endpoint (TASK-1781)

Add ?focus=REF&depth=N to GET /workspaces/{ws}/graph. When focus is set,
BFS-traverse typed edges (undirected) out from the ref up to depth hops
(default 2, clamped to [1,5]) and return only that neighborhood's nodes +
edges. Without focus the whole-workspace behavior is unchanged.

- The focused item is always included, even when terminal (you asked to
  view it); neighbors honor the existing include_terminal filter.
- Neighborhood is intersected with the visibility-filtered item set, so a
  guest can't infer hidden items from dangling edges.
- Node-count cap (maxFocusNodes=200) stops BFS expansion early and sets a
  new GraphResponse.Truncated flag (omitempty — whole-workspace payload
  shape unchanged) so the client can offer expand-on-click.
- An unknown/invisible focus ref returns 404.

Tests: depth bounds + clamping, both-direction traversal, terminal focus
node inclusion, terminal-neighbor filtering, cross-collection typed edges,
unknown ref 404, and truncation.

Parent: PLAN-1780.

* fix(server): preserve true child_count in focus mode per Codex review (round 1)

In focus mode child_count was derived from the depth/cap-filtered edge
set, so a boundary parent whose children fell outside the neighborhood
reported child_count=0. The web UI gates hub-label and children-pill
visibility on child_count > 0, so those would wrongly hide.

Count children over the full visible item set instead (terminal filter
on the child preserved), independent of the focus subgraph. This also
reproduces the whole-workspace semantics exactly. Added a regression
test (focused parent with a child beyond depth still reports count=1).

Parent: PLAN-1780.

xarmian 10a55d1d5c feat(auth): accept provider=apple in cloud oauth-login/link/unlink (TASK-1773) (#714)
* feat(auth): accept provider=apple in cloud oauth-login/link/unlink (TASK-1773)

Sign in with Apple (PLAN-1772, App Store 4.8) needs pad to recognize
'apple' as an OAuth provider. The oauth-login, oauth-link, and
oauth-unlink handlers each hard-rejected anything but github/google;
DRY the triplicated literal into supportedOAuthProviders +
isSupportedOAuthProvider and add apple.

The rest of the path is already provider-agnostic: find-or-create user,
auto-link, the oauth_provider_not_linked gate for existing accounts, and
the verified-email requirement all work unchanged. Storage
(users.oauth_providers) is a free-form JSON array with no DB constraint,
so no migration.

Prerequisite for the pad-cloud /auth/apple/native endpoint (TASK-1774).

* test(auth): cover apple via oauth-link handler (Codex nit)

Prove the shared isSupportedOAuthProvider allowlist is wired through the
link call site, not only oauth-login. oauth-unlink shares the same gate
(unit-tested via TestIsSupportedOAuthProvider).

xarmian 35cc26daaf fix(web): collection cards show real child-item progress; child-progress endpoint (BUG-1509) (#710)
* BUG-1509: show real child-item progress on non-plan collection cards

Backend: extract collectionChildrenProgress helper from handlePlansProgress
and expose it at GET /collections/{collSlug}/child-progress with identical
visibility/guest-grant filtering. handlePlansProgress refactored to delegate
to the shared helper (no duplication). Route registered in the existing
/{collSlug} subrouter alongside checkbox-progress.

Frontend: +page.svelte fetches child-progress + checkbox-progress in parallel
for non-plans collections; per-item merge prefers child-progress (label
"tasks") when total>0, falls back to checkbox counts (label "done"). ItemCard
extended to render progress.label when present. ChildItems.svelte render gate
fixed to include error state so a failed /children fetch surfaces instead of
silently vanishing.

Tests: TestCollectionChildProgress covers happy path (linked children counted
correctly), zero-children items (present with total=0), 404 for unknown
collection, and restricted-member visibility gate (empty response for hidden
collection, not a data leak).

* fix: include_archived on child-progress and progressLabel desync (codex r2)

P1: GetAllItemProgress now accepts includeArchived bool; the parent-row
filter (AND p.deleted_at IS NULL) is conditioned on it, mirroring
CollectionCheckboxProgress. handleCollectionChildrenProgress reads
?include_archived=true and threads it through. handlePlansProgress
hardcodes false — no contract change there. collectionChildProgress()
client method gains opts?: { includeArchived? } with qs() serialisation.
Both call sites in +page.svelte (loadCollection and refreshProgress) now
pass includeArchived to the child-progress fetch.

P2: refreshProgress plans branch now sets progressLabel = 'tasks' so a
sync-triggered refresh after a failed initial plans load renders with the
correct label. progressLabel = 'done' moved inside the non-plans try block
(symmetric with plans) so a thrown fetch leaves the label in whatever
state the previous collection set, not silently desync'd.

Tests: TestCollectionChildProgress extended — archives parentA, confirms
it drops from default response and reappears with include_archived=true.

* fix: thread includeArchived through childrenDoneFiltersForCollection (codex r3)

GetAllItemProgress conditionally drops the p.deleted_at IS NULL parent
filter when includeArchived=true, but the filter-discovery call at the
top of the function — childrenDoneFiltersForCollection — still had the
filter hardcoded. If a child collection's only parent links pointed to
archived parents, that collection was absent from the done-semantics map,
and those children fell back to default status terminals rather than the
collection's configured done field — producing wrong done counts.

Fix: childrenDoneFiltersForCollection gains an includeArchived bool param;
the JOIN on items p conditions p.deleted_at IS NULL on it, exactly mirroring
the main query. GetAllItemProgress passes includeArchived through. The only
other caller of this helper (GetItemProgress via childrenDoneFiltersForParent)
is unaffected — that path is a separate function and never surfaces archived
parents.

Test: TestCollectionChildProgress extended with a "Widgets" collection whose
done field is `state` (terminal: "shipped") — not the default `status` field.
An archived task parent links two widget children (one shipped, one open); no
live task parent links into widgets, so the filter-discovery bug would drop
the collection from the map and produce done=0. The test asserts done=1 and
was verified to fail on the pre-fix code.

xarmian 1bd3e52230 feat(web): graph SSE live layer — glow/pulse on touched nodes (TASK-1736) (#704)
* feat(web): graph SSE live layer — glow/pulse on touched nodes (TASK-1736)

The graph now feels alive while agents work: item events from the
workspace SSE stream flash the touched node toward white and fade it
back over 45s (a lazy 2s prune interval animates the decay and stops
itself when idle). Structural events (created/archived/restored) and
item_updated fold into one trailing-debounced refetch (1.5s) through
the existing loadGraph stale-token path; comment_created is glow-only.
New items arrive glowing via a pending-uuid stash resolved when the
refetch lands. Pulse composes before focus-mode dimming so touched
nodes still flicker subtly in the dimmed crowd. Selection clears when
the selected item leaves the payload (archived under focus mode).

Events correlate via a uuid→ref bridge rebuilt per payload — the
graph endpoint now emits each node's item UUID alongside the ref.

Parent: PLAN-1730.

* fix(web): refetch graph on sync_required per Codex review (round 1)

items_bulk_updated and replay-buffer gaps route through onSyncRequired,
not onItemEvent — the graph stayed stale after bulk archive/move/assign
until the next single-item event. Fold both into the existing debounced
refetch.

xarmian 77dcd07ecd feat(web): graph search fly-to + collection/status/role filters (TASK-1735) (#703)
* feat(web): graph search fly-to + collection/status/role filters (TASK-1735)

Toolbar grows a type-ahead search (ref/title over the post-filter node
list; ArrowUp/Down + Enter picks, Escape closes without stealing the
page's deselect) that routes through the existing selectNode() — same
camera fly-to, highlight, and detail card as a click. Client-side
filters subset the rendered graph: collection chips with palette dots,
status chips, and a role select (hidden when no node carries a role;
the graph endpoint now emits the assigned agent-role slug per node).
Edges survive only when both endpoints do; counts read "X of Y" while
filtered. Workspace switch resets filters; show-completed doesn't.
Filter changes deselect so a vanished node can't strand focus mode.

New GraphToolbar.svelte owns the presentational toolbar; the page owns
authoritative filter state (CONVE-1688 discipline unchanged).

Parent: PLAN-1730.

* fix(web): close graph search dropdown on blur per Codex review (round 1)

The dropdown opened on focus/input but only closed on pick or Escape,
leaving stale results floating over the canvas after clicking away.
The result buttons already pick on mousedown+preventDefault, so the
input never blurs mid-pick — a plain onblur close is safe.

* fix(web): gate search Escape on dropdown visibility per Codex review (round 2)

Escape in a focused-but-empty search now falls through to the
page-level deselect instead of being swallowed by the searchOpen flag.

xarmian db3917f6d2 feat(web): /graph route MVP — lazy-loaded 3D force graph (TASK-1733) (#701)
* feat(web): /graph route MVP — lazy-loaded 3D force graph (TASK-1733)

New full-viewport graph page at /{username}/{workspace}/graph rendering
the TASK-1731 endpoint via 3d-force-graph. Three.js loads only through
a dynamic import inside onMount, landing in its own ~1.3MB chunk
referenced solely by the graph route node — entry bundle unchanged.

Node color = collection (local hex palette; the chart PALETTE's CSS
vars can't reach WebGL), node size = 1 + 2×child_count, blocks edges
red with directional arrows, structural links brighter than soft ones.
Click navigates to the item page (ResolveItem accepts refs in the slug
param). Active items by default with a "Show completed" toggle that
refetches in place; workspace switches refetch with a stale-response
guard. Teardown via _destructor + ResizeObserver disconnect.

Nav: 'graph' added to destinations.ts (NavKey, RESERVED_SLUGS, primary
destinations, getActiveKey) and a Sidebar entry after Insights — the
mobile More sheet picks it up from the shared source automatically.

Parent: PLAN-1730.

* fix: clear stale canvas on workspace switch + reserve 'graph' collection slug per Codex review (round 1)

1. The renderer-sync effect now pushes empty graphData when the
   reactive payload is null (workspace switch in flight / load error)
   instead of early-returning — the previous workspace's nodes no
   longer linger behind the loading overlay.
2. 'graph' added to reservedCollectionSlugs so a collection can't
   shadow the /{username}/{workspace}/graph route, matching the
   frontend's RESERVED_SLUGS.

xarmian 93220845a0 feat(server): workspace graph endpoint — nodes + typed edges (TASK-1731) (#699)
* feat(server): workspace graph endpoint — nodes + typed edges (TASK-1731)

GET /api/v1/workspaces/{ws}/graph returns the whole workspace as
{nodes, edges} in one call, feeding the 3D graph view (PLAN-1730).
Nodes carry ref/title/collection/status/is_terminal/child_count/
updated_at; edges are typed (parent | blocks | implements | related |
wiki-link), with wiki-link edges sourced from the PLAN-1593 reverse
index, deduped per pair, self-links dropped.

Default response is active items only; ?include_terminal=true returns
the full history. Visibility follows the dashboard model (collection
visibility + guest item-level grants), and edges are filtered to the
visible node set so hidden items can't be inferred from dangling
endpoints.

Parent: PLAN-1730.

* fix(server): normalize graph edge types to advertised vocabulary per Codex review (round 1)

item_links can carry split_from / supersedes / wiki_link beyond the
documented enum. Map stored types to the hyphenated graph vocabulary
(wiki_link → wiki-link, split_from → split-from), dedupe (source,
target, type) so a stored wiki_link row and a parsed [[...]] mention
of the same pair emit once, and document the full edge enum. Unknown
future link types pass through rather than being dropped.

* fix(store): close graph edge enum against unknown link types per Codex review (round 2)

Route stored link types through models.NormalizeItemLinkType; values
it rejects (possible via the import path — no DB CHECK on
item_links.link_type) degrade to 'related' instead of leaking
undocumented edge types past the advertised vocabulary.

xarmian 72d8963c4c fix(timeline): resolve collab-snapshot diffs + collapse autosave bursts (BUG-1612) (#691)
Item timelines showed two collab-snapshot problems:

1. Artifacts: the timeline endpoint (ListItemVersionsBeforeTime) served
   diff versions unresolved, so TimelineVersionCard fed raw diff-match-patch
   patch text into DiffView. Add GET /items/{slug}/versions/{versionID}
   (handleGetItemVersion -> Store.GetItemVersionResolved) and have the card
   lazily fetch resolved content the first time a diff version is expanded.

2. Clutter: every ~5s web-editor autosave flushes a collab-snapshot version.
   buildTimeline now collapses uninterrupted collab-snapshot bursts (within
   10 min, no intervening event) to their newest entry, and the source badge
   renders as "Autosave" instead of the raw slug.

Adds TestCollapseAutosaveBursts. Known limitation (accepted): collapse is
page-local, so a 150+ cross-actor autosave chain can leak one row per
"Load more" page — gated by the 1h version throttle, degrades gracefully.

xarmian ae8173b42d fix(server): gate ref-resolver admin bypass on bearer auth (BUG-1618) (#690)
* fix(server): gate ref-resolver admin bypass on bearer auth (BUG-1618)

resolverWorkspaceRole returned "owner" for any platform admin regardless
of auth surface, so a bearer-borne admin (PAT / CLI / MCP) could probe
the existence of refs in workspaces they never joined via the /-/r/ 302
redirect — leaking workspace + ref existence plus the owner username and
collection slug in the redirect target.

Site 1 (real fix): thread isBearerAuth(r) into resolverWorkspaceRole and
gate the admin branch on !authIsBearer; the workspace-owner check stays
unconditional. Bearer-admins fall through to the member-then-grants check
(membership-only stance, matching BUG-1616/1617). Cookie-session admins
keep the owner bypass so the web-UI affordance is preserved. Added
TestRefResolver_AdminBearer_404OnNonMemberWorkspace (bearer -> 404) and
TestRefResolver_AdminCookie_StillRedirects (cookie -> 302).

Site 2 (audit, no logic change): the workspace sort-order bulk-update's
silent-skip needs no auth gate — UpdateWorkspaceSortOrder is scoped to
the caller's own workspace_members row, so a non-member PATCH touches
zero rows (no cross-ws write or leak), and handleListWorkspaces has been
membership-only for all authenticated users including admins since
BUG-982. Rewrote the stale comment to record both facts.

Parent: BUG-1617. Sibling: BUG-1616.

* fix(server): deny bearer-admin grant fallback in resolver per Codex review (round 1)

A bearer admin who isn't a member but holds a stray collection/item grant
got "guest" from resolverWorkspaceRole, then checkItemVisible's own
`user.Role == "admin"` bypass returned visible — reopening full resolver
access + 302 URL leakage the BUG-1618 fix was meant to close. Add the
membership-only guard (return "" for bearer-admin non-members before the
grant fallback), matching RequireWorkspaceAccess and the SSE/collab
sibling gates. New regression test TestRefResolver_AdminBearer_404EvenWithGrant.

xarmian a5c7fc986e fix(attachments): grant-aware upload auth so share-link editors can attach (BUG-1661) (#688)
handleUploadAttachment gated on requireMinRole("editor") — a workspace-level
check — but the editor and comment composer offer the paste/drop upload
affordance based on grant-aware edit permission. A grant-based editor (guest
with an item/collection edit grant via a share link, no workspace editor role)
could type/post but hit 403 on upload.

Server: read ?item_id early (before spooling the body); when present and
resolvable, authorize via requireEditPermission against the item's grant chain,
else fall back to requireMinRole("editor") for free-floating uploads (new-item
creation, storage settings). Reordered the nil/getWorkspaceID checks above auth.

Client: upload() now also sends item_id as a query param so the server can
authorize before spooling. Threaded the item UUID through Editor.svelte (both
mount sites) and CommentEditor.svelte (ItemTimeline composer + the 3
TimelineCommentCard composers via comment.item_id).

Test: TestUpload_GrantBasedEditorCanAttach — guest with an item edit grant gets
201 with ?item_id and 403 without it (confirms the editor-role fallback didn't
widen access).

* feat(share): include saved views in collection share payload (TASK-1681)

Expose the collection's saved views on the public /s/{token} payload so the
read-only view switcher (TASK-1682) can render and toggle them. Fetched via
Store.ListViews (ordered by sort_order) and projected to a public shape
under collection.views — name, slug, view_type, config (parsed object),
is_default, sort_order — with internal UUIDs and timestamps stripped.
Always emits an array (never null); empty when the collection has no saved
views, so the switcher falls back to settings.default_view.

Extends the SharePayload TS type with PublicShareView + an optional
collection.views array (additive) for TASK-1682 to consume.

Parent: PLAN-1677.

* fix(share): pin distinct view sort_order in test per Codex review (round 1)

CreateView inserts sort_order=0 and now() is second-granularity, so the two
test views could tie on (sort_order, created_at) and SQL could return either
order, flaking the position-based assertion. Set explicit sort_order 0/1 and
assert on it.

xarmian 873d351e24 feat(server): enrich collection share payload with settings, schema, item content (TASK-1678) (#680)
The public collection share-link resolver (`handleResolveShareLink`,
`collection` branch) previously returned only `{name, icon, description}`
plus a flat `{title, ref, fields}` per item. The public viewer at
`/s/{token}` therefore could not reproduce the owner's chosen view
type, grouping, field labels, or status colors, and had no body to
show for an inline read-only row expand.

Enrich the public collection DTO with:
- `collection.settings` — a presentation-only projection of
  CollectionSettings (`layout`, `default_view`, `board_group_by`,
  `list_sort_by`, `list_group_by`), emitted as a parsed JSON object.
  The authoring-only fields (`quick_actions`, `content_template`) are
  deliberately excluded from the public path.
- `collection.schema` — the parsed CollectionSchema object
  (`fields[]` with key/label/type/options/terminal_options/suffix),
  emitted as an object rather than a raw JSON string.
- `items[].content` — each item's markdown body, for the inline
  read-only row expand decided in TASK-1684.

Both settings and schema are parsed defensively: a malformed stored
JSON blob is simply omitted from the response rather than failing the
resolve. No internal IDs, creator info, workspace internals, or
timestamps are exposed. Adds an HTTP-level test asserting the enriched
shape and guarding against leakage of forbidden tokens.

Frontend integration (consuming this shape) is TASK-1680; security
review of the content exposure is tracked in TASK-1685.

xarmian 1d9a611508 feat(api): bulk restore op for undo (TASK-1674 backend) (#675)
Add a 'restore' verb to the bulk endpoint so an undo of a bulk archive
is one call. The loop resolves include-deleted for restore (archived
rows are hidden from ResolveItem); applyBulkOp calls store.RestoreItem,
mapping UNIQUE-constraint races to a conflict and sql.ErrNoRows to
not-found, and logging action="restored". Also make
ResolveItemIncludeDeleted UUID-aware (mirrors ResolveItem) so restore
resolves by the ids the bulk response returns.

Adds 'restore' to the TS BulkItemOp / BulkItemsRequest union and a Go
test (archive → restore round-trip by id).

xarmian 57995c5898 fix(sync): moved-out tombstones for cross-visibility collection moves (BUG-1675) (#670)
* fix(sync): emit moved-out tombstones for cross-visibility collection moves (BUG-1675)

/items-changes filtered deltas by an item's CURRENT collection, so an
item moving from a collection a restricted member can see into one they
can't vanished with no eviction signal — the stale, now-unauthorized
row lingered in their local cache until a full rebootstrap.

Server:
- store.ListMovedOutSince: finds items that changed since the cursor,
  are now outside the caller's visible scope, and have a 'moved'
  activity FROM a collection the caller CAN see. Returns id+seq only —
  no destination data leaks (the caller has read access to the source).
- handleListItemsChanges merges these in as moved_out tombstones, then
  seq-sorts + caps the combined stream so pagination stays gap-free.
- Bulk collection moves now log a proper 'moved' activity with from/to
  collection slugs (mirroring handleMoveItem) — the signal the
  tombstone query reads. Previously they logged generic 'updated'.

Client:
- ItemChangeRow gains moved_out; applyDelta hard-evicts those ids from
  RAM + search and queues the IDB delete into the SAME atomic
  cursor-advance tx (persistDelta gains removeIds) so it can't
  resurrect on warm boot.

Full members (nil visibility) skip the extra query entirely — the path
only runs for restricted members/guests.

Tests: store-level matrix (ListMovedOutSince), end-to-end restricted
member /items-changes tombstone, bulk-move 'moved' activity logging.

* fix(sync): tie moved-out tombstone to the move event's seq per Codex review (round 1)

Keying the tombstone on the item's CURRENT seq meant any later change
while it sat in a hidden collection re-emitted a moved_out row — leaking
that an invisible item keeps mutating, and never settling. Stamp the
post-move seq into the 'moved' activity metadata (both single + bulk
move paths) and key the tombstone on THAT seq: it fires once, for the
move that crossed the visibility boundary, and the cursor settles past
it. Moves logged before the seq stamp are skipped (evict on rebootstrap)
rather than risk the re-fire.

Test: re-fire regression (a post-move hidden-collection update must not
re-emit the tombstone).

* fix(sync): page moved-out tombstones by move seq, not current seq per Codex review (round 2)

Ordering/capping candidates by the item's current seq could strand an
item that moved out early (low move seq) but later churned in the hidden
collection (high current seq): it fell past the limit while the cursor
advanced beyond its move seq, never to be emitted again. Collect all
eligible rows, keep the earliest qualifying move per item, sort by move
seq, then apply the limit at a move-seq boundary so dropped rows
re-fetch cleanly on the next poll.

Test: 3 items move out ascending; the earliest churns to a high current
seq; limit=2 must still return the two smallest move seqs, then the
third on the next page with no gap.

* fix(sync): durable item_collection_moves table for moved-out detection per Codex review (round 3)

Moved-out detection read the 'moved' activity row, which is written
after the move commits and best-effort (errors discarded) — so a delta
poll racing the audit write, or a failed write, could advance the cursor
past the move seq and strand the unauthorized item forever.

Record every cross-collection move in a new item_collection_moves table
inside the SAME transaction as the move (MoveItemWithPreCheck), carrying
the workspace seq the move assigned. ListMovedOutSince now reads that
table — fully SQL/indexed (from_collection_id IN visible, MIN(seq) for
multi-hop, current-collection NOT IN visible), no JSON parsing, no
best-effort dependency. The 'moved' activity stays for audit only.

Migration 066 adds the table + indexes. Tests updated to rely on the
durable record (MoveItem writes it) rather than hand-logged activity.

* fix(sync): add Postgres migration for item_collection_moves per Codex review (round 4)

Postgres reads the separate pgmigrations/ tree, so the SQLite-only
migration 066 left item_collection_moves absent on PG deploys — every
cross-collection move would fail at the in-tx insert and moved-out
queries would error. Add pgmigrations/045 with the equivalent table +
indexes.

xarmian dfd3811eee feat(api): bulk-mutation endpoint + single SSE batch event (TASK-1668) (#669)
* feat(api): bulk-mutation endpoint + single SSE batch event (TASK-1668)

Add POST /workspaces/{ws}/items/bulk accepting item IDs + a verb
(archive, move, tag, untag, set-priority, assign). The lane-header
bulk actions operate on a whole filtered lane, so the endpoint emits
ONE items_bulk_updated SSE event and ONE item.bulk_updated webhook for
the batch instead of per-item fan-out.

Reuses the existing store paths (UpdateItemWithPreCheck / MoveItem /
DeleteItem) rather than re-implementing writes; the open-children
guard runs per status-bearing move exactly as the single PATCH path
does (force-overridable). Per-row failures are collected into the
response envelope (updated/failed/total) rather than aborting the
batch. Editor/owner gated.

Frontend client + TS types follow in TASK-1669; UI wiring in TASK-1672.

Parent: PLAN-1667.

* fix(api): per-item visibility + collection-move guard on bulk endpoint per Codex review (round 1)

- Enforce per-item collection visibility (checkItemVisible) in the bulk
  loop so a member with collection_access="specific" can't bulk-mutate
  items in hidden collections by guessing refs; report invisible rows as
  not-found. Also gate the move target collection on visibility.
- Route bulk collection moves through MoveItemWithPreCheck with the
  open-children guard (destination schema), closing the bypass where a
  collection move + terminal status could mark a parent terminal with
  open children. Status-only moves already ran the guard.
- Tests: status-move + collection-move guard coverage (reject + force
  override + mutation-safety).

* fix(web): consume items_bulk_updated SSE event per Codex review (round 2)

The bulk endpoint emits one items_bulk_updated event, but the SSE
service only listened for the fixed ITEM_EVENTS list — so a bulk
mutation left other tabs/sessions stale until an unrelated sync fired.
Route the batch event through the existing sync_required path: it
carries item_ids + a max seq but no per-item field payload, so an
incremental /items-changes delta reconciles every affected row by seq.
Broadcast so peer tabs reconcile too.

* fix(api): scope bulk SSE event per-collection, drop item_ids per Codex review (round 3)

The batch event published with an empty Collection, which the SSE
filter treats as workspace-level: restricted members received bulk
events for hidden collections (leaking item_ids/op/count) while guests
with grants were dropped entirely and stayed stale.

Emit one items_bulk_updated event per affected collection with
Collection set, so the existing visibility filter routes it like any
collection-scoped event. Drop per-item IDs from the SSE payload — a
batch can't be item-grant-filtered for guests on a broadcast bus, so
IDs would leak; recipients reconcile via the /items-changes delta,
which is visibility-filtered server-side (Seq carries the cursor). The
webhook (a trusted workspace integration) keeps the full id list.

Test asserts the event is collection-scoped and carries no item_ids.

* fix(api): bulk collection move notifies both source and target scopes per Codex review (round 4)

A cross-collection move only emitted a batch event for the target
collection, so a restricted member watching the source lane wouldn't
reconcile the item leaving it. Notify both the source and target
collection scopes for moves (still no per-item IDs). Test asserts both
events fire.

* fix(api): suppress itemless batch SSE events for item-grant-only subscribers per Codex review (round 5)

A guest/restricted member with only item-level grants in a collection
could still receive the collection-scoped items_bulk_updated event
(itemless), learning op/count/timing for items they can't see. Extract
the SSE visibility filter into sseEventVisibleFor and add a rule:
itemless collection-scoped events go only to subscribers with FULL
collection access; item-grant-only subscribers reconcile their granted
items via the next resume/reconnect /items-changes sync instead.

Adds a unit test covering the visibility matrix.

* fix(api): validate status override against target schema on bulk collection move per Codex review (round 6)

A status override on a collection move was applied after MigrateFields
but never validated against the target schema, so an out-of-options
value (e.g. status=bogus) could be written. Run ValidateFields on the
final field map before the move. Test asserts the invalid value is
rejected per-row and the item stays put.

* feat(comments): comment editing backend — user_id, UpdateComment, PATCH, SSE (TASK-1663)

Foundation for comment editing (PLAN-1662). No migration — comments.user_id
already exists (012_users.sql) but was never written or exposed.

- Populate user_id on create/reply: CreateComment takes an explicit userID
  param (passed from currentUserID by the handlers, not via the request body
  so it can't be spoofed). Expose user_id on models.Comment + all comment
  SELECTs/scans. The workspace export path is left as-is — imported comments
  keep NULL user_id (admin-only edit), matching the pre-identity fallback.
- Store.UpdateComment(id, body): replaces body + bumps updated_at; the
  comments_fts_update trigger re-indexes.
- PATCH /workspaces/{ws}/comments/{commentID}: author-or-admin only
  (canEditComment), rejects empty body. Editing is an authorship op, distinct
  from delete (item editors). NULL user_id → admin-only.
- comment_updated SSE event: broadcast from the handler; added to the web
  sse allowlist + ItemTimeline refresh set.
- web: api.comments.update(), Comment.user_id type.

Tests: author edits own (200), non-author non-admin (403), admin edits
anyone (200), empty body (400), NULL-user_id comment is admin-only.

Parent: PLAN-1662.

* fix(account): detach authored comments on account deletion per Codex review (round 1)

Now that TASK-1663 populates comments.user_id (FK to users.id),
DeleteAccountAtomic would fail on the FK for any user who authored a
comment. Null comments.user_id for the user before deleting the row —
comments live on in soft-deleted/other workspaces; the display-name
author is preserved and the comment just becomes admin-only to edit.
Regression test added.

xarmian e179c595e4 feat(comments): paste/drop image attachments in comments + inline render (IDEA-1650) (#663)
* feat(comments): paste/drop image attachments in comments + inline render (IDEA-1650)

Comment composers were plain textareas with no upload path, and comment
bodies rendered markdown without an attachment resolver — so a
`pad-attachment:UUID` reference would never display. This wires both
halves end to end:

- Compose: paste or drop files into the comment composer (ItemTimeline)
  and the reply box (TimelineCommentCard). A shared helper
  (commentAttachments.ts) splices an "Uploading…" placeholder at the
  caret, uploads concurrently via the existing attachment API, and swaps
  each placeholder for its `pad-attachment:UUID` markdown ref (image
  syntax for image MIMEs, link/chip syntax otherwise — mirrors the
  editor's split). Submit is gated while uploads are in flight.
- Display: ItemTimeline lazily HEAD-probes each referenced UUID (reusing
  the editor's fetchAttachmentMetadata cache), builds a reactive
  resolver, and threads it into renderMarkdown for comments and replies
  so refs render as inline images / file chips.
- Orphan GC: comment uploads leave attachments.item_id NULL (like the
  editor), but the GC reference scan only checked items.content/fields.
  Renamed AttachmentReferencedInItems -> AttachmentReferenced and
  extended it to scan comments.body, so a screenshot referenced only
  from a comment isn't reclaimed after the grace period. Added
  TestOrphanGC_KeepsAttachmentReferencedFromComment.

Follow-up refinement (thumbnails + click-to-expand lightbox) captured as
IDEA-1660.

* fix(comments): escape markdown-significant chars in attachment filenames per Codex review (round 1)

Filenames containing [ ] or backslash could break the generated
![name](pad-attachment:...) markdown. P2 (grant-aware upload auth) is a
pre-existing endpoint-wide gap shared with the rich editor — tracked as
BUG-1661, not fixed here to keep the PR focused.

* fix(comments): preventDefault on dragover for file drops per Codex review (round 2)

Browsers only deliver a file drop to a custom target if its dragover
cancels the default; without it the page navigates to the file. Gated
on isFileDrag so in-textarea text drag-drop is unaffected.

* feat(tags): render tag chips on cards, list rows, and the item header (TASK-1655)

- lib/types: shared parseTags() — defensive JSON-array parse + case-insensitive
  dedupe; reused by ItemCard and the detail page (which drops its inline dupe).
- ItemCard (shared by BoardView + ListView): a clickable tag-chip row. The card
  is an <a>, so chips are buttons that goto the tag page with stopPropagation —
  same pattern as the existing star/PR/status controls — avoiding nested anchors.
- Item detail header: tag chips as real <a> links to the tag page.

Chips link to /[ws]/tags/[tag]; those pages arrive in TASK-1657.

Parent: PLAN-1652.

* feat(tags): dedicated tag pages (index + per-tag aggregated view) + nav (TASK-1657)

Folded into the chip-display PR because the chip links require the routes to
exist — without them /[ws]/tags/[tag] is swallowed by the generic
[collection]/[slug] route and hits the item error path (Codex PR #660 round 1).

- /[ws]/tags — index: tag cloud with per-tag item counts (GET /tags), each
  linking to its tag page.
- /[ws]/tags/[tag] — aggregated view: cross-collection items for the tag,
  grouped by collection (the shared axis across heterogeneous status enums),
  modeled on the starred page. A static `tags` segment takes routing
  precedence over [collection], so the collision is resolved.
- Sidebar: a Tags nav entry; `tags` added to the reserved-slug guard so the
  route isn't mistaken for a collection.

Parent: PLAN-1652.

* fix(tags): reserve 'tags' collection slug + tighten Tags nav active-match per Codex review (round 2)

- backend: add 'tags' to reservedCollectionSlugs so a collection can't be
  created with a slug that the /tags routes would shadow.
- Sidebar: isTagsPage now matches exactly /tags or the /tags/ boundary, not
  any /tags* prefix (e.g. a 'tags-collection' path no longer marks it active).

* fix(tags): don't drop item-granted rows whose collection isn't listable per Codex review (round 3)

A restricted member can see an item via item-level grant without being able to
list its collection, so getCollection() missed and the row was dropped while
still counted (count != rendered). Synthesize a minimal collection from the
item's embedded collection_* metadata so those rows render (empty schema =
ItemCard omits status/priority).

* 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 333f509274 fix(store): monotonic seq tiebreak for same-second status transitions (TASK-1643) (#655)
* fix(store): monotonic seq tiebreak for same-second status transitions (TASK-1643)

Resolves the documented historical-snapshot precision edge: created_at is
second-precision and ids are random UUIDs, so "latest transition <= T" was
nondeterministic for 2+ same-second hops on one item. Add a monotonic `seq`
(MAX+1 at insert, like items.seq; assigned inside the workspace seq lock so
per-item order is serialized — cross-row dupes are harmless) and order the
as-of-T reconstruction by created_at DESC, seq DESC, id DESC.

- migrations 065 / 044: add seq + backfill existing rows chronologically
  (ROW_NUMBER over created_at,id), dual-dialect.
- seq set on all four insert sites (update/move/create-seed hooks + backfill).
- reportSnapshotAsOf ORDER BY uses seq; doc caveat updated (now fixed).
- Test inserts same-created_at rows where id-order and seq-order DISAGREE,
  proving seq is the tiebreak.

Parent: PLAN-1628.

* fix(store): insert backfill create-seeds before hops so seq stays chronological per Codex review (round 1)

The backfill inserted activity hops first, then create-seeds, so a seed got a
HIGHER seq than a same-second hop — and since the as-of query orders by
created_at DESC, seq DESC, the seed (the initial state) wrongly won "latest"
for same-second create-and-change histories. Buffer the hops during the
activity scan and insert them AFTER the seeds, so every hop's seq exceeds its
item's seed seq (a seed is always chronologically first; on a created_at tie
the hop's higher seq correctly wins). Adds a seed-seq-below-hop test.

Encode the independent-reviewer principle (a reviewer model different from the
implementer catches more than self-review) as opt-in onboarding guidance — no
tool-specific operational lore (that stays ours).

- New generic library convention "Independent AI code review" (quality,
  on-pr-create, nice-to-have): states the principle; names review tools as
  examples (a review CLI, claude review, a GitHub bot) without operational depth.
- /pad onboard build (B3) + audit (A3) steps: the agent notes its own model
  (the implementer), probes for / asks about a review tool, and when a
  different-model reviewer is available, proposes activating the convention,
  naming the detected tool (e.g. codex) as the concrete suggestion. Skips when
  the only reviewer would be the same model. Never blocks.

* feat(report): opt-in 'what shipped' completed-items list (TASK-1641)

Add ?include_items=true → completed_items[{ref,title,collection,completed_at}]
on the report: items that reached a positive terminal in the window, deduped
by item (newest completion first), capped at 500 with
completed_items_overflow_count. Same positive-terminal source as
totals.completed (joins live items, deleted_at IS NULL), so the list reconciles
with the count. Opt-in so the interactive dashboard stays count-only; the
print/export report (TASK-1642) requests it.

Web ReportData gains completed_items + the api.report.get includeItems flag.
Parent: PLAN-1628.

* fix(report): scope completed-items list to the item's current visible collection per Codex review (round 1)

The list scoped transitions by st.collection_id (visible at completion) but
returned the item's CURRENT title/ref/collection — so an item completed while
visible then moved to a hidden collection could leak its hidden collection
slug/prefix + current title to a restricted caller. Require i.collection_id to
be in the resolved (scoped) collection set on both the count and list queries.
Adds a move-to-hidden-collection visibility test.

xarmian 4368c576c5 feat(insights): reconstruct historical WIP + status snapshot for past periods (TASK-1640) (#650)
* feat(insights): reconstruct historical WIP + status snapshot for past periods (TASK-1640)

For a past period (offset>0), reconstruct the status-distribution and WIP
snapshot as-of the window end from status_transitions, instead of hiding them.
An item's status as-of-T = the to_status of its latest transition on the
collection's done field with created_at <= T (NOT EXISTS "no later transition",
dual-dialect, no window functions); only items that existed at T (created_at
<= T) and weren't deleted by T are counted. WIP age is measured against T.

offset 0 keeps the live-from-items path (ground truth for now). Frontend drops
the interim hide so the cards show in the past, with a note that they're
reconstructed (older periods approximate — the backfill parsed the
debounce-coalesced activity log).

Parent: PLAN-1628.

* fix(insights): items-first historical snapshot + period-aware WIP subtitle per Codex review (round 1)

1. reportSnapshotAsOf started from status_transitions, so an item that existed
   at T but had no done-field transition (e.g. created with fields={}) was
   dropped — undercounting historical WIP vs the live path, which treats a
   missing done value as open. Start from items and correlated-subquery the
   latest transition <= T (NULL → empty/open). Adds a no-transition-open test.
2. WIP card subtitle "Open items right now" → "Open as of this period" when
   viewing a past period (offset>0), matching the reconstructed snapshot.

* fix(store): record done-field CLEARS as transitions so historical snapshot is accurate per Codex review (round 2)

The capture hook only recorded a transition when newStatus != "", so clearing
a done field (e.g. done → unset) wasn't logged — and as-of-T reconstruction
would still show the old terminal value, undercounting historical open work.
input.Fields is the full merged blob (CLI/handler merge before write), so
newStatus == "" genuinely means cleared, not omitted. Drop the `!= ""` guard
in both the update and move hooks so X → "" is recorded. Adds a clear test.

* docs(store): document current-collection attribution as an accepted historical-snapshot limitation (Codex review round 3)

reportSnapshotAsOf attributes items to their CURRENT collection for past
periods (not the collection at t). Reconstructing historical collection
membership needs move-history replay (status-preserving moves record no
transition) — disproportionate, and consistent with the same current-collection
attribution the backfill + completed-by-collection already use. Documented as a
deliberate best-effort limitation rather than built; items rarely move.

* docs(store): document same-second transition-ordering limitation + file follow-up (Codex review round 4)

reportSnapshotAsOf's "latest transition <= t" is nondeterministic for 2+
same-second status hops on one item (second-precision created_at + random
UUID ids). Rare; documented as a known limitation and tracked as a follow-up
task (monotonic ordering column / sub-second timestamps).

Let users personalize the Insights surface, persisted per-user per-workspace:
toggle which metric cards show, and remember the window + collection filter.

Backend:
- migrations 064/043: user_report_layouts (user_id, workspace_id, config JSON,
  PK(user_id,workspace_id), ON DELETE CASCADE) — dual-dialect.
- models.ReportLayout (hidden_cards/default_window/default_collections) +
  ReportCardIDs/ValidReportWindow validation.
- store.GetReportLayout / SaveReportLayout (ON CONFLICT upsert, both dialects).
- GET/PUT /workspaces/{ws}/report/layout — per-user; PUT sanitizes window +
  filters hidden_cards to the known card set. web client + TS type.

Frontend (Insights page):
- loads the saved layout, hydrates window/collections/hidden cards
- a "Customize" panel toggles each card (SvelteSet-backed); each section gated
  on !hiddenCards.has(id); Totals always shown
- debounced auto-save, gated on a per-workspace `hydrated` flag so it never
  saves during load or stomps another workspace's layout on switch

Single config per user (no named/multiple layouts — deliberate v1 scope).
Parent: PLAN-1628.

* fix(insights): save layout only on explicit user changes, not on load per Codex review (round 1)

The auto-save $effect ran once after hydration (loadLayout assigns reactive
state, then flips hydrated=true), firing a PUT /report/layout on mere page
view — which 401s on no-user/legacy-token sessions and bounces the user to
/login. Replace the effect with a scheduleSave() called only from explicit
handlers (toggleCard, selectWindow, toggleCollection, clearCollectionFilter);
hydration never saves. Also capture wsSlug at schedule time and drop the
pending save if the workspace changes mid-debounce, so A's edit can't land

Route is /insights (owner directive); sidebar link is TASK-1636. Card
toggling + saved layouts are TASK-1634. Svelte 5 runes; MCP-validated;
npm run check 0 errors. Parent: PLAN-1628.

* fix(web): reset insights collection filter on workspace change per Codex review (round 1)

SvelteKit reuses the route component across workspace param changes, so a
collection filter selected in workspace A leaked into B — sending A's slugs to
B's /report, which the server scopes to an empty set (no match) → empty report
for a non-empty workspace. Track the previous wsSlug in a plain (non-reactive)
var and clear selectedCollections on an actual workspace change before
snapshotting, so the new workspace starts unfiltered. Loop-safe.

* fix(web): guard insights report fetch against stale/out-of-order responses per Codex review (round 2)

loadReport left the previous report visible during an in-flight fetch and wrote
responses unconditionally, so switching workspace A→B showed A's data under B's
URL, and a slow older request could overwrite a newer selection. Add a plain
request-sequence counter: capture seq at fetch start, commit report/error only
when seq is still the latest, and only the latest request clears `loading`.
Also clear report/collections on an actual workspace change so A's data doesn't
linger under B while B loads.

* fix: reserve 'insights' collection slug to avoid route shadowing per Codex review (round 3)

The static /[username]/[workspace]/insights route shadows the dynamic
/{collection} route, so an 'insights'-slugged collection would be unreachable.
Add 'insights' to reservedCollectionSlugs (server, blocks creation) and to the

xarmian d9fab3ea02 feat(report): cycle-time + WIP/aging metrics (TASK-1631) (#642)
* feat(report): cycle-time + WIP/aging metrics (TASK-1631)

Extend GET /workspaces/{ws}/report with two metric blocks:
- cycle_time: created→positive-terminal duration for completions in the
  window — overall median + p90 + per-collection medians.
- wip: point-in-time open items (done field NOT a terminal value), open count,
  median age, fixed aging bands (<1d/1-7d/7-30d/>30d), per-collection median age.

Medians/percentiles computed in Go from raw durations (dual-dialect: neither
SQLite nor Postgres has a portable percentile). Completed/WIP queries join live
items (deleted_at IS NULL), consistent with the rest of the report.

Wires through web ReportData TS types + `pad project report` rendering.
Tests: cycle-time median (backdated 48h), WIP open-count + aging bands,
percentile helper. Parent: PLAN-1628.

* fix(report): well-formed cycle_time/wip arrays on empty-scope path per Codex review (round 1)

The no-visible-collections early return left cycle_time.by_collection,
wip.aging_buckets, and wip.by_collection as nil → marshaled null, violating
the TS array contract for guests/restricted callers. Initialize those nested
slices in the ReportData literal so every path (including the early return) is
well-formed. Adds a JSON-shape regression test for the empty-scope case.

xarmian a1d09c90df feat(report): windowed project report endpoint + DateBucket dialect (TASK-1630) (#638)
* feat(report): windowed project report endpoint + DateBucket dialect (TASK-1630)

GET /workspaces/{ws}/report?window=week&collections=tasks,bugs returns a
time-bucketed report: created-vs-completed throughput, net flow,
completed-by-collection, and a current status-distribution snapshot.

- Dialect.DateBucket(column, granularity) — day/hour bucketing via fixed-width
  substring on the UTC RFC3339 TEXT (identical + exact on SQLite + Postgres;
  avoids SQLite 'Z'-parsing fragility). Routes all report date math through it.
- store.GetReport: resolves per-collection done field + positive terminals
  (terminal options minus rejected/cancelled/etc.), counts completions from
  status_transitions and created from items.created_at, zero-fills buckets.
- HTTP handler + route; web ReportData type + api.report.get client.
- Tests: throughput/totals, negative-terminal exclusion, status distribution,
  collection filter, non-status done-field, out-of-window exclusion, hourly
  day-window, DateBucket per granularity. Dual-dialect via testStore.

Fixes the response contract that TASK-1632/1633/1635 consume (noted on them).
Parent: PLAN-1628.

* fix(report): scope report to caller's visible collections per Codex review (round 1)

The endpoint sits under RequireWorkspaceAccess (members, restricted members,
guests), but GetReport resolved ALL workspace collections — letting a caller
with access to one collection infer hidden collections' slugs, created/
completed counts, and status distribution. Mirror the dashboard: the handler
computes visibleCollectionIDs() and GetReport restricts to that set
(ScopeToVisible). Empty visible set → empty report. Aggregate reports are a
full-collection-visibility feature; item-level grants aren't surfaced in
workspace-wide counts.

* fix(report): correct visibility scoping for all-access + item-grant callers per Codex review (round 2)

Round 1's scoping had two bugs in how it read visibleCollectionIDs:
1. nil means "all-access" (admin / collection_access=all), but the handler
   treated nil as an empty visible set → all-access users got an EMPTY report.
   Now nil → ScopeToVisible stays false (full workspace report).
2. For guests, visibleCollectionIDs includes collections visible only via
   item-level grants; passing those to the aggregate report leaked the whole
   collection's counts. Now mirror the dashboard: when item-level grants are
   present, scope to fullCollIDs (full-access collections only).

Adds report handler tests (owner full report + default window) alongside the
store-level scoping test.

* fix(report): bearer-aware admin visibility scoping per Codex review (round 3)

visibleCollectionIDs grants ANY platform admin an unrestricted (nil) view, but
RequireWorkspaceAccess suppresses the platform-admin bypass for bearer auth and
falls through to membership (BUG-1616/1617). So a bearer admin (PAT/CLI/OAuth)
who is only a restricted workspace member could read the full workspace report.

Extract reportVisibleCollections(): gate the admin bypass on cookie auth; for
everyone else resolve actual member/guest visibility, and when item-level
grants exist scope to the full-access collection set only. Adds a cookie-vs-
bearer scoping test (cookie admin unrestricted, bearer restricted-member scoped
to the granted collection, end-to-end through GetReport).

* fix(report): exclude soft-deleted items from completion counts per Codex review (round 4)

status_transitions rows survive a soft delete (only a HARD delete cascades
them), so a completed-then-soft-deleted item still counted toward completed /
completed_by_collection while created and status_distribution (which filter
deleted_at IS NULL) excluded it — inconsistent totals. Join live items in both
completed queries. Adds a regression test.

xarmian 5dfc2921b2 feat(store): structured status-transition log + backfill (TASK-1637) (#637)
* feat(store): structured status-transition log + backfill (TASK-1637)

Add a status_transitions table capturing every item status change as a
structured, queryable row — written in the same tx as the item update and
never debounced — so the Reports surface (PLAN-1628) can reliably compute
the completed-throughput and cycle-time series.

- migrations/063 + pgmigrations/042: status_transitions table (dual-dialect),
  indexed on (workspace_id, created_at) and (item_id, created_at)
- write-path hook in UpdateItemWithPreCheck records from→to on status change
- BackfillStatusTransitions: one-time startup replay parsing the historical
  activities.metadata.changes blob (mirrors BackfillWikiLinks), gated on an
  empty table; wired into cmd/pad/main.go
- models.StatusTransition + tests (capture, multi-hop, no-op, parser, backfill)

Spike (TASK-1629) found the activity log records status changes only as a
human-readable, debounce-coalesced metadata string — unusable for aggregation.
This is the foundation TASK-1630 (report aggregation) builds on.

* fix(store): record status transitions on item move too per Codex review (round 1)

MoveItemWithPreCheck rewrites fields outside UpdateItemWithPreCheck, so a
status-changing move override (pad item move ... --field status=done) was
not recorded in status_transitions, making the table non-canonical. Insert
the from→to row in the move tx as well, stamped with the target collection.

Adds move-path capture tests (status override + status-preserving move).

* fix(store): make status-transition backfill idempotent per Codex review (round 2)

The empty-table gate isn't atomic, so concurrent replays (a future
multi-replica Postgres deploy; single-instance today) could double-insert
historical rows and overcount reports. Give backfilled rows a deterministic,
activity-derived primary key ("bf_" + activity id) and a dialect-aware
conflict clause (ON CONFLICT DO NOTHING / INSERT OR IGNORE) so a re-run
no-ops instead of duplicating. Count only rows that actually land.

Write-path rows keep using a random newID(), so live data never collides.

* fix(store): accurate from_status under lock + document backfill caveats per Codex review (round 3)

1. from_status was read from the pre-lock `existing` snapshot. When no
   precheck ran, a concurrent update (serialized behind the locks we hold)
   could make it stale. Capture the status from a fresh in-tx read BEFORE
   the UPDATE (reading after would see the new value and drop the hop).
   Applied to both UpdateItemWithPreCheck and MoveItemWithPreCheck.

2. Backfill stamps historical rows with the item's current collection_id;
   reconstructing the collection at each past status change would require
   replaying move history. Documented as a best-effort, historical-only
   caveat (exact for the common never-moved case; live write/move paths
   stamp the collection at transition time).

* feat(store): track collection done-field + seed create-time transitions per Codex review (round 4)

1. Generalize capture from hard-coded "status" to each collection's done
   field (DoneFieldKey: status, or BoardGroupBy field like stage/result for
   hiring/interviewing). Add a field_key column recording which field the
   row tracks (robust to later BoardGroupBy changes). Applied to update,
   move, and backfill paths.

2. Seed a create-time "entered initial status" transition on CreateItem and
   in the backfill (Pass 2), so an item created directly in a terminal value
   still counts as a completion. Initial value reconstructed from the item's
   earliest recorded change, else its current value.

Also: item_id FK is ON DELETE CASCADE so hard-deletes clean up transitions.
Tests cover non-status done-field, create-in-terminal, create-seed, and
cascade-on-delete; full store suite green.

* fix(deps): bump go-jose/v3 to v3.0.5 to clear GO-2026-4945 (BUG-1619)

GO-2026-4945 — Go JOSE panics in JWE decryption. Reachable via
github.com/ory/fosite v0.49.0 from internal/server/handlers_oauth.go's
handleOAuthAuthorize (govulncheck call chain into jose.ParseSigned /
JSONWebSignature.Verify / etc).

Drop-in dependency bump, no API changes. Post-bump govulncheck reports
0 reachable vulnerabilities.

Discovered during v0.6.0 release pre-flight (PLAYB-1160 step 1) — CI
run 26518095093 failed govulncheck after the most recent main push,
even though nothing about that change touched OAuth. Same shape as
TASK-1583 (the golang.org/x/net bump earlier this cycle).

* test(open-children-guard): filter readParentRef by SourceRef to fix race flake (BUG-1621)

readParentRef was matching the first LinkType=="parent" link in
GET /items/{ref}/links's response — but GetItemLinks returns links
in BOTH directions (WHERE source_id = ? OR target_id = ?). After
TestOpenChildrenGuard_PatchAtomicRejectionPreservesParentLink attaches
a child task to its target plan, the response contains two parent
links: target→oldParent AND child→target. ORDER BY created_at DESC
ties at sub-microsecond resolution; SQLite tiebreaks on rowid; under
race-scheduler CI load the child→target link sometimes lands first,
the helper returns the target's OWN ref as the "parent", and the
setup-sanity assertion fails with "parent should start as PLAN-1,
got PLAN-3" (where PLAN-3 = target itself).

Filter on SourceRef == itemRef so only the item's OUTGOING parent link
matches. Test-file-only change.

Latent since PR #571 (IDEA-1494, e59d390). Caught now during v0.6.0
release pre-flight on PR #634.

xarmian 83716a65fc fix(backlinks): scope cross-workspace admin enumeration to membership for bearer auth (BUG-1617) (#633)
Companion to BUG-1616. The admin platform role granted unrestricted
cross-workspace visibility at the STORE layer too: `GetCrossWorkspaceBacklinks`
ran `ListWorkspaces()` for any user with `Role=admin`, and
`ResolveBacklinksVisibility` short-circuited to `(nil, nil)` for the
same role check. Both fired BEFORE the BUG-1616 middleware gate could
deny the request, so a bearer-borne admin (CLI / PAT / MCP) could
enumerate cross-workspace backlinks from every workspace on the server.

Policy: bearer-borne admin gets STRICT membership enumeration — no
guest-grants fallback. Matches RequireWorkspaceAccess's membership-only
stance from BUG-1616. Cookie-session admin keeps the global view
(preserved web-UI affordance).

Threads `authIsBearer bool` from the HTTP boundary (via the new
isBearerAuth helper) into the store layer:

- `Store.ResolveBacklinksVisibility` — admin bypass now gated on
  `!authIsBearer`; bearer-admin falls through to the regular
  member/grants pipeline. Also tightens the "no visibility" return
  shape from `(nil, nil)` to non-nil empty slices so callers can
  distinguish "unrestricted" from "explicit empty" — closes a
  latent ambiguity that doesn't fire in current callers but would
  if any future caller bypassed the upstream membership filter.
- `Store.GetCrossWorkspaceBacklinks` — new switch:
    - cookie admin       → ListWorkspaces (unchanged)
    - bearer admin       → GetUserMemberWorkspaces (NEW, strict
                            membership; no grants fallback)
    - non-admin          → GetUserWorkspaces (unchanged; memberships
                            ∪ guest-grant workspaces)
- `Server.guestResourceFilterCore` — admin short-circuit now gated
  on `!isBearerAuth(r)`; bearer-admin delegates to the store-side
  helper with the bearer signal threaded through.
- `handlers_backlinks.go` — pass `isBearerAuth(r)` to
  `GetCrossWorkspaceBacklinks`.

New `Store.GetUserMemberWorkspaces` helper — the first half of
`GetUserWorkspaces` without the UNION-with-grants block. Used by the
bearer-admin path; existing callers continue to use `GetUserWorkspaces`
unchanged.

Tests:

- `wiki_links_xws_test.go`:
  - Updated `TestWikiLinks_CrossWorkspaceAdminSeesAllWorkspaces` to
    cover both `authIsBearer=false` (cookie, sees all) and
    `authIsBearer=true` (bearer, sees none) cases.
  - NEW `TestWikiLinks_CrossWorkspaceBearerAdminGrantOnlyWorkspaceFiltered`
    — bearer-admin with a guest grant on workspace C still gets ZERO
    cross-ws rows from C (Codex round-2 finding).
  - NEW `TestWikiLinks_CrossWorkspaceBearerAdminSeesMemberWorkspaces`
    — positive control: bearer-admin who IS a member sees the row.
  - Extended `TestResolveBacklinksVisibility_RoleMatrix` with two
    bearer-admin subtests (non-member workspace → empty; member
    workspace → unrestricted).
- NEW `handlers_backlinks_admin_bearer_test.go::TestCrossWorkspaceBacklinks_AdminBearer_OnlySeesMembershipWorkspaces`
  — full HTTP integration test, both cookie and PAT-bearer subtests.
- All existing callers updated to pass `false` for `authIsBearer`
  (preserves current cookie-session / non-admin behavior).

Verification: full `go test ./...` green; `make lint` clean;
Codex round 2 review CLEAN.

xarmian f48c99e421 fix(auth): scope admin platform role to cookie session auth (BUG-1616) (#632)
The admin platform role granted owner-level access to every workspace on
every surface, including bearer-borne callers (PATs on /api/v1, CLI
session bearers, PATs/OAuth on /mcp). A user with "All current
workspaces" consent on an MCP client — or a leaked admin token of any
kind — could reach data the admin never joined.

Policy: the admin global bypass now fires only for cookie session auth
(web UI / SPA / /console/admin). Bearer-borne callers fall back to a
strict workspace_members check (membership-only; no guest-grants
fallback either).

Gated four sites in lockstep:

- RequireWorkspaceAccess (internal/server/middleware_auth.go) — covers
  /api/v1/* routes; emits the existing not_a_member MCP authz denial
  metric on bearer-admin denials.
- handleSSE entry (internal/server/handlers_events.go) — adds an
  explicit GetWorkspaceMember check for bearer-borne admin after
  resolveWorkspace's global slug lookup.
- sseSubscriberStillHasAccess (internal/server/handlers_events.go) —
  per-tick revalidation now matches entry-time policy.
- computeSSEVisibility (internal/server/handlers_events.go) —
  bearer-admin gets a real VisibleCollectionIDs filter instead of
  "no filtering"; a bearer-admin who's a member with
  collection_access=specific is now correctly scoped.
- authorizeCollabAccess (internal/server/handlers_collab.go) —
  WebSocket collab upgrade gate; same membership-only stance.

New shared helper isBearerAuth(r) folds two signals (Authorization:
Bearer header OR ctxIsAPIToken stash) so MCP-dispatcher synthesized
requests and CLI session bearers are both covered. Mirrors the dual
check middleware_csrf.go already uses.

Tests (9 total):

- middleware_auth_admin_token_gate_test.go (5) — PAT denied/allowed
  permutations, CLI session-bearer denial, cookie-session bypass
  preserved.
- handlers_admin_bearer_gate_test.go (4) — SSE revalidation,
  visibility filter, collab WebSocket auth.

Companion BUG-1617 (store-layer admin bypass in backlinks visibility)
tracked separately.

xarmian 225fb4a53f Wire upgrade CTAs with Stripe-ready billing flow (TASK-800) (#629)
* feat(billing): add billing_available session flag gated on PAD_BILLING_AVAILABLE (TASK-800)

Add Server.billingAvailable field set by SetBillingAvailable(), called from
cmd/pad/main.go when PAD_BILLING_AVAILABLE=true|1. Expose the flag as
billing_available in both the setup-state and authenticated session payloads
(value: cloudMode && billingAvailable) so the web UI can gate Stripe CTAs
without a code change at deploy time. False by default.

* feat(billing): wire upgrade CTAs, checkout POST flow, plan section, clickable limit toasts (TASK-800)

Frontend prep work gated on authStore.billingAvailable (from billing_available
session field). When false, upgrade buttons remain hidden and the "coming soon"
note stays in place — flip PAD_BILLING_AVAILABLE=true at deploy time.

Changes:
- client.ts: add billing_available to AuthSession; add api.billing.createCheckoutSession()
  (POST /billing/checkout → parse {url} → caller does window.location.href)
- auth.svelte.ts: billingAvailable getter
- console/billing: replace STRIPE_AVAILABLE=false with $derived(authStore.billingAvailable);
  fix GET→POST on upgrade buttons; add ?checkout=cancelled banner; add cancelled style
- console/settings: new cloud-mode-gated "Plan" section with current plan + upgrade/manage link
- All 11 limit-hit sites: replace plain-text '/console/billing' appendage with
  toastStore.show(msg, 'error', 6000, '/console/billing') so the toast is clickable

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 3a04c06684 fix(backlinks): suppression must query item_links, not items.parent_id (TASK-1607 followup) (#626)
* fix(backlinks): suppression must query item_links, not items.parent_id (TASK-1607 followup)

The initial TASK-1607 fix routed the parent↔child "Mentioned in"
suppression through `items.parent_id`. That column is empty in
production — 0 of 3,923 items in a live workspace had it set —
because the API path (handlers_items.go::handleCreateItem) writes
parent relationships via Store.SetParentLink, which only touches
the `item_links` table with link_type='parent' (source=child,
target=parent — see migration 023). The deprecated parent_id
column is vestigial. Result: the filter was a no-op everywhere
the user actually encountered the duplication.

Caught when testing on fhir-core/TASK-397 — a task with ~20
children all wiki-linking it, none filtered. Direct sqlite
inspection confirmed: parent_id NULL on every row, but 2,022
'parent' rows in item_links workspace-wide.

The fix:

- Replace the SQL predicate in GetBacklinks and CountBacklinks
  with two NOT EXISTS subqueries against item_links — one for
  "source is not a child of target", one for "source is not the
  target's parent". Both use idx_links_source / idx_links_target
  for O(1) lookups per candidate row.
- Drop the TargetParentID field from BacklinksVisibility. The
  store no longer needs the handler to plumb it through — the
  parent relationship is queried from item_links directly. Same
  pattern as children-suppression: both are unconditional and
  self-contained.
- Update handlers_backlinks.go to remove the dead plumbing.
- Rewrite createChildItem test helper to use SetParentLink (the
  production path) instead of CreateItem with ParentID (the dead
  column path). The original test helper made all the
  suppression tests pass falsely against the wrong storage.
- Add TestWikiLinks_SuppressionUsesItemLinksNotParentIDColumn:
  sets up the parent ONLY via SetParentLink, asserts parent_id
  column stays NULL, asserts suppression still works. Regression
  guard against routing the filter back through the dead column.

The existing 4 suppression tests still pass against the corrected
mechanism (they now exercise SetParentLink under the hood).
Cross-workspace path remains untouched — item_links is workspace-
scoped same as parent_id was, so the doc comment on
GetCrossWorkspaceBacklinks stays valid.

Refs IDEA-1601.

* fix(backlinks): consult items.parent_id alongside item_links for suppression (Codex P2)

Codex review of the prior commit raised a P2: ItemCreate.ParentID
and ItemUpdate.ParentID still write to items.parent_id directly
without creating an item_links row (handlers_items.go only calls
SetParentLink for the `parent` field path, not for direct
ParentID JSON). The HTTP/CLI path is unaffected — empirically
zero items in production have parent_id set — but a direct
store-API caller (test, future import path, or any code that
bypasses the handler) could leave the suppression invisible
to one of the two storage shapes.

Belt-and-suspenders: the relClause now AND's two pairs of
predicates so suppression triggers whichever shape the parent
relationship lives in.

- Children-suppression: NOT EXISTS item_links AND items.parent_id
  comparison
- Parent-suppression: NOT EXISTS item_links AND a correlated
  subquery against items (NOT EXISTS items t WHERE t.id = ?
  AND t.parent_id = s.id) so we don't have to plumb target's
  parent_id through

New regression test (TestWikiLinks_SuppressionFallsBackToItemsParentIDColumn)
exercises the column-only path: CreateItem with ParentID, NO
SetParentLink, asserts items.parent_id IS set and item_links is
empty, then asserts suppression still works in both directions.

CountBacklinks updated identically to stay in lockstep with
GetBacklinks pagination math.

* fix(backlinks): suppression must cover childLinkTypes ('parent' AND 'implements') (Codex round 2)

Codex round 2 caught: the Child Items panel and GetChildItems
both inflate `childLinkTypes = {"parent", "implements"}` (see
items.go:18). My filter only suppressed link_type='parent'. An
'implements' child therefore still appeared in Mentioned in
even though it was visually duplicated in the Children section
above.

Use childLinkTypeSQL() in both NOT EXISTS subqueries (children
direction and parent direction) so the filter stays in lockstep
with the canonical inclusion rule. If a future link type is
added to childLinkTypes, the suppression picks it up automatically.

New regression test
TestWikiLinks_SuppressionCoversImplementsChildLinkType wires a
child via CreateItemLink(link_type=implements) and asserts the
mention is suppressed — pins the lockstep with childLinkTypes.

This was the actual mechanism for the original fhir-core/TASK-397
report: TASK-441 et al. carry "**Implements:** [[TASK-397]]" in
their bodies AND are linked as 'parent' (Pad uses 'parent' for the
explicit hierarchy in that workspace), but a sibling case where
only 'implements' was set would have leaked through round 1's fix.

xarmian 4aff8c70a0 feat(backlinks): suppress parent↔child mentions from "Mentioned in" panel (TASK-1607) (#625)
On a parent's page (typically a PLAN with many child TASKs), the
"Mentioned in" panel was dominated by child tasks that wiki-link
back to their parent. Those children are already listed in the
Children section directly above the panel, so the same items
appeared twice on screen and buried genuine cross-references
(sibling plans, retro docs, etc.). Symmetric problem on a child's
page: the parent shows up in "Mentioned in" even though it's
already in the "Parent: …" header.

Suppression is server-side in two parts, modeled on the existing
self-link filter in GetBacklinks (s.id != targetItemID):

1. Children-suppression — always-on. Source rows where
   s.parent_id = targetItemID are dropped. Uses the existing
   targetItemID parameter; no API change. NULL-safe form so
   orphan items still surface (raw `s.parent_id != ?` would
   silently drop NULL parent_id rows under SQL three-valued logic).

2. Parent-suppression — opt-in. New TargetParentID *string field
   on BacklinksVisibility (zero value = nil = no parent
   suppression, keeping the ~50 existing test callsites valid).
   When set, the source row whose id == TargetParentID is dropped.
   The handler passes item.ParentID from the resolved target.

Both apply to CountBacklinks identically so the
handlers_backlinks.go same-ws/cross-ws pagination math
(which depends on count-vs-fetch agreeing) stays correct.
GetCrossWorkspaceBacklinks is unaffected — parent_id is
workspace-scoped, so a cross-ws source can't be the target's
parent or child by construction. Doc comment added noting this.

Tests:
- ChildMentionOfParentSuppressed: headline case
- ParentMentionOnChildPageSuppressed: symmetric case with/without
  TargetParentID
- SiblingMentionsNotSuppressed: control — siblings of a shared
  parent that wiki-link each other still surface
- OrphanBacklinksUnaffected: regression for the NULL-safe form
- PaginationStableAfterSuppression: page 1 + page 2 hit all
  filtered rows exactly once with no duplicates

Promoted from IDEA-1601. Follow-up to [[PLAN-1593]] (which
shipped the original wiki-link backlinks reverse index).

xarmian c1c9f2ef97 fix(share): guard nil grants/share-link slices to prevent ShareDialog TypeError (BUG-1598) (#624)
The Share dialog threw "Cannot read properties of null (reading 'length')"
on any item/collection with zero grants. Store.ListCollectionGrants /
ListItemGrants return a nil slice when there are no rows, which writeJSON
encoded as JSON null; the client then hit grants.length on null.

Server: nil-to-[]{} guard in handleListCollectionGrants and
handleListItemGrants, mirroring the existing pattern in
handlers_share_links.go.

Client: defensive ?? [] in ShareDialog.svelte's loadGrants and
loadShareLinks so a null body can't reach .length checks.

xarmian 35ac7552eb feat(backlinks): UI panel + mention badge + CLI + MCP (Phase 3) (#623)
* feat(backlinks): UI panel + mention badge + CLI + MCP (Phase 3)

Phase 3 of PLAN-1593 (TASK-1596). Surfaces the backlinks index
shipped in Phases 1/2a/2b across every place users live: web UI,
CLI, MCP.

What changed

Web UI
- New BacklinksPanel.svelte at web/src/lib/components/. Fetches via
  api.items.backlinks (new method) and renders inbound `[[...]]`
  references grouped by source collection. Per-row: collection icon,
  ref + title, snippet, relative timestamp, optional `(displayed as)`
  override, faint workspace badge on cross-ws rows. Pagination via
  "Show older" when the page is full. Collapses entirely when the
  count is zero — no header, no whitespace, no empty surface for
  items with no inbound links.
- Mention badge ("📎 N") in the item-page action bar next to the
  Timeline button. Hidden when N=0; smooth-scrolls to the panel.
  Wired via onCountChange callback so badge + panel stay in sync.
- New Backlink TypeScript type at web/src/lib/types/index.ts mirroring
  internal/models/backlink.go; new api.items.backlinks(ws, slug, opts)
  client method.

CLI
- `pad item show <ref>` enriched with inline top-5 "Mentioned in"
  section in TTY mode (skipped when empty), and a backlinks_top
  array in JSON output. Hint at the dedicated `pad item backlinks`
  command when the inline list hits the 5-row cap.

MCP
- New `pad_item.action: backlinks` — passes through to
  `pad item backlinks <ref>` with optional `limit` (default 50,
  max 300) + `offset` params. Bumps ToolSurfaceVersion 0.5 → 0.6
  with a backwards-compatible additive note in version.go. Updated
  the catalog_readonly_test fixtures so the cmdhelp drift check
  passes.

Test plan
- [x] go build ./... + go test ./internal/mcp/ green
- [x] make check (lint + Go + web) green
- [x] make install + restart
- [x] pad item show TASK-1596 shows --- Mentioned in --- inline
- [x] pad item show TASK-1596 --format json includes backlinks_top
- [x] svelte-check 0 errors
- [ ] /codex review --loop → CLEAN

Out of scope (filed as separate ideas if anyone asks)
- Force-directed graph visualization of the link network
- Broken-links report (target_item_id IS NULL feeds it but it's its
  own feature)

* fix(backlinks): unique each-block key for multi-occurrence rows (Codex round 1)

Codex round 1 P1: BacklinksPanel keyed each row by source_item_id,
but the server preserves multiplicity — a source body that mentions
the target three times produces three Backlink rows (Phase 1 design
decision, covered by TestWikiLinks_RepeatedRefStoresMultipleRows).
Duplicate keys in Svelte's #each are rejected at dev time and
silently reuse DOM in prod, so the panel would render only one of
the N rows from a multi-mention source.

Fix: compose a unique key per row via new rowKey(bl, index) helper:
`${source_item_id}|${snippet}|${index}`. The snippet usually
differs across positions (centered on the bracket byte offset);
the index suffix is the unconditional tie-breaker.

xarmian 905876af04 feat(backlinks): cross-workspace wiki-links + request-independent ACL (Phase 2b) (#622)
* feat(backlinks): cross-workspace wiki-links + request-independent ACL (Phase 2b)

Phase 2b of PLAN-1593 (TASK-1597). Completes the wiki-link reverse
index by indexing and surfacing `[[workspace::REF]]` cross-workspace
references. Builds on Phase 2a's title work (PR #621). Phase 3
(TASK-1596) owns the UI/MCP/CLI rendering changes.

What changed

- internal/store/backlinks_visibility.go (new): request-independent
  ACL helper `Store.ResolveBacklinksVisibility(userID, workspaceID,
  includeDeletedItems)`. Mirrors the role-determination + collection-
  merge logic from server.guestResourceFilterCore but doesn't depend
  on a request context, so cross-ws traversal can compute per-source-
  workspace ACLs without a `workspaceRole(r)` lookup. The Codex
  planning-round review caught the prior plan reusing the request-
  scoped helper as a hidden architectural cost; this is the resolution.

- internal/server/server.go: guestResourceFilterCore refactored to
  delegate to the new store helper. Keeps the request-scoped wrapper
  signature stable for all existing handler call sites; only the
  internals move.

- internal/links/extract.go: lift the Phase-2a workspace_ref emit
  gate. WikiLinkKindWorkspaceRef now flows through ExtractWikiLinks
  alongside ref and title kinds. parseBody recognition was already
  in place from earlier rounds.

- internal/store/wiki_links.go: WikiLinkKindWorkspaceRef branch in
  replaceWikiLinks stores (target_workspace_id, target_ref) verbatim,
  resolving the slug→ID via new resolveWorkspaceSlugTx (with per-call
  cache so repeated `[[ws::X]]` in one body don't re-query). Unknown
  slugs persist with target_workspace_id=NULL — broken-link
  semantics, identical to existing ref/title patterns.

- internal/store/wiki_links.go: new `Store.GetCrossWorkspaceBacklinks`
  enumerates accessible workspaces via Store.GetUserWorkspaces (which
  includes guest-only access — broader than membership query), then
  per-workspace computes visibility via ResolveBacklinksVisibility and
  runs the SQL backlinks query with the per-ws (FullCollectionIDs,
  GrantedItemIDs) predicate inline. Results sorted by updated_at DESC
  in Go, paginated globally. Per-workspace safety cap (offset+limit)
  prevents one workspace from dominating the global slice.

- internal/store/wiki_links.go: new `Store.CountBacklinks` for same-ws
  pagination boundary detection. Needed so the handler knows where
  the cross-ws tier begins for pages 2+.

- internal/models/backlink.go: new `SourceWorkspaceSlug string`
  (omitempty) field. Populated only by cross-ws rows; same-ws rows
  leave it empty so the existing wire shape is preserved.

- internal/server/handlers_backlinks.go: union pagination across
  same-ws and cross-ws tiers. Same-ws first (matches the renderer's
  UI mental model — your own workspace's links at the top of the
  panel). Count-based slice math handles pages 2+ correctly when
  same-ws is exhausted.

Tests

- internal/links/extract_test.go: workspace_ref forms emit correctly
  (bare, display alias, mixed case, invalid-slug fallback to title).
- internal/store/wiki_links_xws_test.go (new): six cross-ws scenarios
  plus a role-matrix test:
  - end-to-end cross-ws index + query
  - non-member sees nothing
  - guest with collection grant sees only that collection
  - guest with item grant sees only the granted item
  - unknown workspace slug → broken row, no query results
  - same-ws rows leave SourceWorkspaceSlug empty
  - ResolveBacklinksVisibility role matrix (admin/full member/guest
    with grants/non-member non-grant)

Out of scope (Phase 3 / TASK-1596)

UI rendering of cross-ws backlinks (workspace badge + workspace-
prefixed ref), MCP `pad_item.action: backlinks` cross-ws fields,
CLI display tweaks.

PLAN-1593 / TASK-1597.

* fix(backlinks): admin enumeration + cross-prefix ref fallback + unbounded perWsCap (Codex round 1)

Three P2 findings from Codex round 1 against PR #622:

Finding 1 — admin users miss cross-ws backlinks. `GetUserWorkspaces`
returns only memberships + grant-only guest workspaces, but
RequireWorkspaceAccess (middleware_auth.go:481) gives admins
implicit access to every workspace. An admin querying for backlinks
would silently miss links from workspaces they're not explicitly a
member of.

Fix: in GetCrossWorkspaceBacklinks, branch on user.Role:
  - admin → s.ListWorkspaces() (every non-deleted workspace)
  - non-admin → s.GetUserWorkspaces (memberships + grants)
Stale user IDs return empty result rather than erroring.

Finding 2 — cross-ws ref matching doesn't handle cross-prefix moves.
Same-ws is immune because target_item_id is resolved at parse time
and survives renames/moves; cross-ws resolves at query time, so a
`[[other-ws::OLD-42]]` row written before the target moved from
OLD→NEW collection wouldn't match a query under the NEW ref.

Fix: in queryCrossWorkspaceBacklinksForWorkspace, dual ref-match
clause: exact `LOWER(wl.target_ref) = LOWER(?)` OR
`LOWER(wl.target_ref) LIKE LOWER('%-N')` where N is the item_number
from the target ref. Pad prefixes are alphanumeric with no internal
`-`, so trailing `-N` uniquely identifies the number suffix — no
false positives like "TASK-142" matching "%-42" (LIKE anchors to
the trailing literal).

Finding 3 — per-workspace cap of 1000 silently broke pagination
beyond offset>=1000. The 1000 ceiling was defensive paranoia; the
correct math is offset+limit per workspace (worst case all rows
come from one workspace and the global slice still needs that
many).

Fix: drop the 1000 ceiling. perWsCap = offset+limit unconditionally.
For runaway offsets the per-workspace transfer cost is proportional;
documented as a known characteristic (callers shouldn't be paging
past offset=10000 anyway).

Regression tests:
- TestWikiLinks_CrossWorkspaceAdminSeesAllWorkspaces: admin sees
  cross-ws backlink without being a workspace member.
- TestWikiLinks_CrossWorkspaceRefNumberFallback: move target to new
  collection, query under new ref, old-ref-stored row still surfaces.

PLAN-1593 / TASK-1597.

* fix(backlinks): honor OAuth/MCP token workspace allow-list (Codex round 2)

Codex round 2 P1: cross-workspace backlinks bypassed the OAuth/MCP
token's workspace allow-list (TASK-952). A token consented for
workspace A but with the underlying user having access to B would
still surface source rows from B via the cross-ws query — leaking
data outside the token's consent scope.

Fix: thread `allowedWorkspaceSlugs []string` through
GetCrossWorkspaceBacklinks. Handler populates it from
TokenAllowedWorkspacesFromContext(r.Context()):

  - nil → no token gate (PAT or pre-TASK-952 token, allow all)
  - "*" wildcard → allow all
  - explicit list → strict slug membership

Workspace enumeration skips any source workspace whose slug isn't
in the allowlist. The same-ws path is unchanged because
RequireWorkspaceAccess already gated the target workspace against
the allow-list (so we only reach this handler when the target IS in
the list).

Regression test in wiki_links_xws_test.go covers four shapes: nil,
wildcard, target-only (blocks cross-ws), explicit source-workspace
(allows cross-ws).

PLAN-1593 / TASK-1597.

* fix(backlinks): normalize limit at handler boundary (Codex round 3)

Codex round 3 P2: the backlinks handler parsed ?limit=N but didn't
normalize it before computing the same-ws/cross-ws pagination
split. GetBacklinks and GetCrossWorkspaceBacklinks each clamp >300
internally, but the handler's 'remaining := limit - len(sameWs)'
used the original (potentially huge) value. With ?limit=301 and
more than 50 same-ws backlinks, the first page would mix cross-ws
in before same-ws was exhausted, violating the documented tier
order.

Fix: clamp 'limit' to <=300 at the handler boundary, before any
pagination math runs.

PLAN-1593 / TASK-1597.

* fix(backlinks): normalize same-workspace [[ws::REF]] to ref-kind (Codex round 4)

Codex round 4 P2: `[[<current-ws>::TASK-1]]` was being indexed as a
workspace_ref row with target_workspace_id = current workspace. But
the same-ws GetBacklinks query requires target_item_id (workspace_ref
rows leave it NULL), AND GetCrossWorkspaceBacklinks explicitly skips
the target workspace — so the link rendered and navigated correctly
in the UI but no backlink ever surfaced.

The renderer's L307 short-circuits same-workspace fully-qualified
form to behave identically to `[[REF]]`; the index must follow.

Fix: in replaceWikiLinks, normalize a workspace_ref link to ref-kind
when its slug resolves to the current workspace. The promotion
canonicalizes the ref (via new links.CanonicalizeRef exported alias)
so `[[ws::task-5]]` stores the same canonical shape as `[[TASK-5]]`.

Tests:
- TestWikiLinks_CrossWorkspaceSameWorkspaceQualifiedNormalized:
  same-ws fully-qualified `[[ws::REF]]` surfaces in same-ws backlinks
  and is absent from cross-ws backlinks.

PLAN-1593 / TASK-1597.

* fix(backlinks): same-ws qualified ref miss doesn't title-fallback (Codex round 5)

Codex round 5 P2: my round-4 normalization was too aggressive. It
promoted `[[<current-ws>::REF]]` to ref-kind and let the regular
ref branch handle it — including the title-fallback path that
runs on ref miss.

But the renderer's same-ws qualified branch (markdown.ts:472-481)
does NOT title-fallback: a ref miss in that path returns the
wiki-link verbatim (broken). Only the bare `[[REF]]` path
(markdown.ts:513) falls through to title lookup.

So my normalization could create ghost backlinks for source bodies
like `[[ws::ISO-9001]]` when an item titled "ISO-9001" exists but
no ISO collection — the renderer renders broken text, but the
index would point at the title-matching item.

Fix: handle same-ws qualified refs inline at the top of the loop,
BEFORE the switch dispatches. Insert as ref-kind row (resolved or
NULL) and `continue` past the switch. Bypasses the title-fallback
path entirely, mirroring the renderer's behavior.

Regression test in wiki_links_xws_test.go pairs same-ws qualified
miss (must NOT title-fallback) with bare ref miss (SHOULD
title-fallback) to lock the asymmetry in.

xarmian c67c167c43 feat(backlinks): title-form wiki-links + rename cascade (Phase 2a) (#621)
* feat(backlinks): title-form wiki-links + rename cascade (Phase 2a)

Phase 2a of PLAN-1593 (TASK-1595). Extends the server-side wiki-link
reverse index from Phase 1's `[[REF-N]]` coverage to also handle
`[[Title]]` and `[[collection/Title]]`. Cross-workspace `[[ws::REF]]`
forms stay gated until TASK-1597 (Phase 2b) ships the request-
independent ACL helper.

What changed
- internal/links/extract.go: lift the Phase-1 emit gate for
  WikiLinkKindTitle; keep WikiLinkKindWorkspaceRef gated.
- internal/store/wiki_links.go: title branch in replaceWikiLinks
  (verbatim target_title storage + case-insensitive resolution),
  resolveTitleTx with full-key match first / `/`-split fallback
  (mirrors renderer order — Codex review caught the inverse on the
  planning round), cascadeTitleRename + resolveBrokenTitleLinks.
- internal/store/items.go: rename cascade fires in-tx on title
  change; create path flips pre-existing broken title rows.
- internal/store/migrations/062 + pgmigrations/041: one-shot
  `DELETE FROM item_wiki_links` so the startup backfill repopulates
  with the Phase 2a vocabulary.
- Tests cover title round-trip, case-insensitive resolution, broken-
  link persistence + later resolution, full rename cascade with
  content rewrite, collection-qualified form, full-key-beats-split
  precedence (regresses Codex finding #3), broken-row flip on rename,
  no-op rename, and self-reference filtering.

PLAN-1593 / TASK-1595.

* fix(backlinks): rename cascade preserves display aliases (Codex round 1)

Codex round 1 against PR #621 caught: the title-rename cascade
selects sources via target_item_id (correctly hitting all rows that
resolve to the renamed item — including aliased and mixed-case
shapes), but the literal `strings.ReplaceAll` rewrite step only
matched `[[Old Title]]` / `[[<slug>/Old Title]]`. Rows from
`[[Old Title|alias]]`, `[[old title]]` (mixed case), or
`[[<slug>/Old Title|alias]]` slipped past the rewrite; the trailing
replaceWikiLinks re-parse then saw the same body, failed to resolve
under the new title, and converted the row to broken — exactly the
regression the cascade exists to prevent.

Fix: new internal/links/RewriteWikiTitle helper handles all four
title-form shapes with case-insensitive title matching and verbatim
display-alias preservation. Cascade swaps from ReplaceAll to this
helper. Unit tests in links_test.go cover the matrix; integration
test in wiki_links_test.go regresses the original failure mode by
mixing all four shapes in one source and asserting all four stay
resolved after rename.

Known limitation documented in the helper: titles containing wiki-
link escape characters (`]`, `|`, `\`) — stored escaped in source
content — don't match the regex's literal old-title segment. Same
limitation exists in the legacy ReplaceTitle helper; promotable if
a real user hits it.

PLAN-1593 / TASK-1595.

* fix(backlinks): retarget qualified-fallback rows on literal-title arrival (Codex round 2)

Codex round 2 against PR #621 (P2): resolveBrokenTitleLinks only
flipped target_item_id IS NULL rows, missing the arrival-order case
where a literal `[[tasks/Setup]]` should win stage 1 over a row
previously resolved via stage 2 (qualified fallback to item "Setup"
in collection "tasks"). The index would stay stale until the source's
content was rewritten — a latent inconsistency between the persisted
backlink and what the renderer would actually show.

Fix: drop the IS NULL constraint on the stage-1 UPDATE. Stage 1
ALWAYS wins per the renderer's order at markdown.ts:541, so any row
with a matching literal title flips to the new item — including
rows currently pointing at a qualified-fallback target. Added a
target_item_id != ? guard so we don't churn rows that already point
at us. Stage 2 keeps the NULL constraint so already-resolved
qualified rows don't churn when another fallback candidate appears.

Regression test in wiki_links_test.go reproduces the exact scenario
Codex described: fallback resolves first, literal arrival steals the
row from the fallback target.

PLAN-1593 / TASK-1595.

* fix(backlinks): renderer parity for [[A|B]] + scope arrival retarget (Codex round 3)

Two findings from Codex round 3 against PR #621:

P1 — parser/renderer parity for [[A|B]] matching literal title "A|B".
The renderer (web/src/lib/utils/markdown.ts:516-525) tries the FULL
body as a title FIRST when a pipe is present, only falling through
to the split interpretation on miss. Our parseBody always split on
the first unescaped pipe, so an item literally titled "A|B" was
indexed as title="A" with display="B" — the index would miss
backlinks the UI shows, or point them at a different "A" item.

Fix: in replaceWikiLinks for title kind, when HasDisplay, try the
full body (Title+"|"+Display) as a title FIRST via resolveTitleTx;
on hit, store target_title=fullBody and drop the display override
(the display segment was actually part of the title). On miss, fall
back to the existing split-key interpretation. The cascade's
RewriteWikiTitle regex correctly handles both storage shapes via
QuoteMeta on the title.

P2 — stage-1 UPDATE was too aggressive after the round-2 fix. The
broad UPDATE (no IS NULL constraint) silently stole backlinks from
legitimately-resolved rows when a SECOND item was created/renamed
to the same title. Titles aren't unique, the renderer's
Array.find() is order-dependent, and silent churn is worse than
no-op stability.

Fix: split resolveBrokenTitleLinks into three updates:
  (1) Plain literal flip — NULL only.
  (2) Qualified literal flip — NULL only.
  (3) Literal-arrival retarget — gated on title containing `/`.
      Only fires for `[[<slug>/Title]]` rows, which are the only
      ones that COULD have been stage-2 qualified-fallback
      resolved. Rows with target_title='Foo' (no slash) can only
      have been stage-1 literal — we don't steal those.

Regression tests:
- TestWikiLinks_LiteralPipeInTitleResolves — `[[A|B]]` resolves to
  item literally titled "A|B".
- TestWikiLinks_LiteralPipeInTitleFallsThroughToSplit — `[[A|B]]`
  falls back to item "A" when no "A|B" item exists.
- TestWikiLinks_SecondItemSameTitleDoesNotStealBacklinks — adding a
  second "Foo" item doesn't redirect the existing backlink.

PLAN-1593 / TASK-1595.

* fix(backlinks): broken pipe-in-body rows keyed on full body (Codex round 4)

Codex round 4 against PR #621: when a source body `[[A|B]]` is
written before any matching item exists, the broken row was stored
with target_title="A" (the split key). If an item literally titled
"A|B" was later created, resolveBrokenTitleLinks looking for
target_title="A|B" couldn't find the row — index went stale while
the renderer's preferred full-body interpretation would correctly
resolve the link.

Fix: when nothing resolves AND a pipe was present (HasDisplay), key
the broken row on the FULL body (Title+"|"+Display) instead of the
split key. resolveBrokenTitleLinks then naturally finds it via the
literal-arrival path.

The remaining asymmetry — a broken row keyed on full body won't pick
up a future split-fallback resolution to a new item titled "A" — is
documented in the code as a v3-promotable limitation. The full-body
path is the renderer's PREFERRED interpretation (markdown.ts:516),
so prioritizing it is the right tradeoff in the rare case both
interpretations could apply.

Regression test in wiki_links_test.go reproduces the scenario:
source written first with `[[A|B]]`, item titled "A|B" created
later, backlink should resolve.

PLAN-1593 / TASK-1595.

* fix(backlinks): scope stage-3 retarget + cascade self-refs (Codex round 5)

Two findings from Codex round 5 against PR #621:

Finding 1 — stage-3 literal-arrival retarget could still steal
backlinks from a legitimate stage-1 literal-match row when a SECOND
item with the same slash-containing title is created. The previous
fix (round 3) gated stage-3 on title containing `/`, which let
through the qualified-fallback retarget case correctly but didn't
distinguish stage-1-resolved rows pointing at a literal twin from
stage-2-resolved rows pointing at the fallback target.

Fix: add an EXISTS check that scopes the flip to rows whose CURRENT
target has a title NOT matching ours. Stage-1 (literal) resolutions
point at items literally titled the same as the row's target_title;
stage-2 (qualified-fallback) resolutions point at items titled just
the trailing segment. The EXISTS clause picks out only the latter.

Finding 2 — self-references on the renamed item went stale on
title-only renames. The cascade's `s.id != renamedItemID` filter
excluded self, but items.go only re-indexes content when
input.Content != nil. So a title-only rename of an item whose body
mentions itself by its old title kept the body's now-broken
`[[Old Title]]` literal in place while the index still recorded a
"working" backlink — drift between renderer state and index state.

Fix: drop the self-exclusion from the cascade SELECT. RewriteWikiTitle
rewrites the renamed item's own content along with everyone else's;
GetBacklinks still hides self-links at query time, so the backlinks
panel behavior is unchanged.

Tests:
- TestWikiLinks_DuplicateSlashTitleNoTheft regresses Finding 1.
- TestWikiLinks_TitleRenameRewritesSelfReferences asserts Finding 2's
  new correct behavior (replaces the prior test that asserted the
  old buggy behavior).

PLAN-1593 / TASK-1595.

* fix(backlinks): ref→title fallback + reorder cascade self-ref (Codex round 6)

Two findings from Codex round 6 against PR #621:

Finding 1 — ref-shaped title fallback missing. parseBody returns
WikiLinkKindRef for `[[ISO-9001]]` (matches refPattern), but if no
ISO-9001 ref-item exists, the renderer falls through to legacy
title lookup (markdown.ts:513) and resolves to an item literally
titled "ISO-9001". The store inserted only a broken ref-kind row
with target_title=NULL, so GetBacklinks never surfaced the backlink
even when the renderer rendered it.

Fix: in replaceWikiLinks' WikiLinkKindRef branch, when resolveRefTx
misses, try resolveTitleTx on the same body. If title resolves,
INSERT as title-kind row with target_title=ref-shaped-body. The
rename cascade catches these correctly via target_kind='title' +
target_item_id. The asymmetry — a future ref-item creation can't
auto-retarget these title-stored rows — is documented as a v3
limitation.

Finding 2 — combined title+content update broke self-ref cascade.
The original order (main UPDATE → replaceWikiLinks(self) → cascade)
wiped self's `target_item_id=renamedItemID` row before cascade ran:
when input.Content contains `[[Old Title]]`, re-indexing self
resolved it as broken (target_item_id=NULL), so cascade's SELECT
missed self for the title+content path.

Fix: reorder so cascade runs BEFORE the self re-index — the
pre-existing wl rows are still intact at cascade time. The final
re-index re-reads items.content from the DB (since cascade may
have rewritten it in-band) rather than using *input.Content
directly; otherwise the re-index would undo the cascade's
self-ref rewrite.

Tests:
- TestWikiLinks_RefShapedFallsThroughToTitle — `[[ISO-9001]]`
  resolves to an item titled "ISO-9001".
- TestWikiLinks_TitleAndContentRenameCascadesSelfRef — combined
  title+content rename with self-ref in new content gets the
  self-ref rewritten by cascade.

* fix(backlinks): ref+pipe→title parity, position-based cascade, scoped self-rewrite (Codex round 7)

Three intertwined fixes addressing Codex round 7 findings against
PR #621:

Finding 1 — ref→title fallback missed pipe-bodies. For
`[[ISO-9001|Spec]]`, renderer tries full-body title "ISO-9001|Spec"
BEFORE falling to bare "ISO-9001" (markdown.ts:516). Our
ref-fallback only tried bare. Extended ref-branch's fallback to
try full body first when HasDisplay, then bare — same order as
the title-branch's stage (a)/(b) pattern.

Finding 2 — cascade corrupted UNRELATED literal-pipe titles. Items
A "Old Title" and B "Old Title|alias" both referenced from one
source; renaming A previously triggered RewriteWikiTitle's regex
`(?i:Old Title)((?:\|...)?)` which matched BOTH A's `[[Old Title]]`
AND B's `[[Old Title|alias]]` — corrupting the B link.

Refactored cascadeTitleRename to be POSITION-BASED: SELECT each
individual wl row with its position + target_title (no longer
DISTINCT sources). Per-row, rewrite the bracket AT THAT EXACT
POSITION via new links.RewriteBracketAt helper. Process rows in
descending position order per source so earlier offsets don't
shift. Brackets whose wl row doesn't resolve to the renamed item
are never visited.

Scoped self-rewrite — title-only renames cascade self
(input.Content == nil); combined title+content renames EXCLUDE
self (input.Content != nil). User-supplied content is
authoritative; auto-rewriting their just-submitted brackets would
surprise them. Mirrors documents.go::updateLinksInTx, which also
leaves the renamed entity's own content alone. Codex round 6
finding 2 is fully addressed: title-only path still rewrites
self-refs, combined path respects user submission and the index
correctly records the bracket as broken (matching what the
renderer would render).

New links.RewriteBracketAt helper with full unit-test coverage:
plain/aliased/qualified/qualified+aliased shapes, case-insensitive
matching, slug-prefix preservation, full-body vs split-key target
disambiguation, out-of-bounds defensive guards. Integration test
TestWikiLinks_CascadeDoesNotCorruptLiteralPipeNeighbor reproduces
Codex round 7 finding 2's scenario.

PLAN-1593 / TASK-1595.

* fix(backlinks): retarget rows pointing at soft-deleted targets (Codex round 8)

Codex round 8 P2: resolveBrokenTitleLinks only considered
target_item_id IS NULL rows as eligible for flip. A row that
resolved to item A and then had A soft-deleted stayed pointing at
deleted A; creating a new item B titled the same as A wouldn't
flip the row, so GetBacklinks(B) missed the backlink the renderer
would actually show (renderer hides deleted-target links).

Fix: introduce a "broken-in-practice" predicate
  (target_item_id IS NULL
   OR NOT EXISTS (
       SELECT 1 FROM items t
       WHERE t.id = item_wiki_links.target_item_id
         AND t.deleted_at IS NULL
   ))
applied to stages 1 (plain literal flip) and 2 (qualified literal
flip). Stage 3 (slash-title literal-arrival retarget) already
considered "current target deleted" implicitly via its title-
mismatch EXISTS check.

Regression test in wiki_links_test.go covers the exact scenario:
A "Foo" resolves a backlink → A soft-deleted → B "Foo" created →
backlink flips to B.

Known limitation deferred to v3: the symmetric case (delete A
while B with same title already exists) doesn't fire any hook
that re-resolves the row. A dedicated DeleteItem hook would close
that gap; not blocking Phase 2a.

PLAN-1593 / TASK-1595.

* fix(backlinks): preserve title whitespace to match renderer (Codex round 9)

Codex round 9 P2: parseBody trimmed whitespace from the body BEFORE
deciding it was a title kind. The renderer doesn't trim before title
matching (markdown.ts:541-543) — `[[ Foo ]]` is matched against
items.title with the surrounding spaces intact, so an item titled
"Foo" wouldn't match. Trimming server-side created index entries
the UI couldn't click — backlinks showed in the panel for links
that the renderer rendered as broken.

Fix: keep an UNTRIMMED unescaped body for title-kind fallthrough,
and a trimmed copy only for ref / workspace_ref SHAPE detection
(refs are whitespace-free by construction, the renderer's
key.trim() at L503 is just typing forgiveness for the ref form).

Tests in extract_test.go:
- `[[ Foo ]]` emits title-kind with Title=" Foo " (whitespace preserved).
- `[[ TASK-5 ]]` still parses as ref (shape detection trims).
- `[[Project  Goals]]` (two spaces inside) preserves internal whitespace.

PLAN-1593 / TASK-1595.

* fix(backlinks): ref→title fallback uses raw untrimmed key (Codex round 10)

Codex round 10 P2: after round 9's title-kind whitespace fix, the
ref→title FALLBACK path still used canonical-trimmed link.Ref for
its title lookup. The renderer's fallback at markdown.ts:541-543
uses the UNTRIMMED key (no .trim() on the title-lookup path), so
`[[ TASK-5 ]]` falling through to title would search " TASK-5 "
(with whitespace) — an item literally titled " TASK-5 " resolves
in the UI but not in our index.

Fix: add a RawKey field to WikiLinkRef capturing the untrimmed
unescaped key for ref kinds. parseBody populates it alongside the
canonical Ref. replaceWikiLinks' ref→title fallback path uses
RawKey (with defensive fallback to Ref for old rows) when
constructing title candidates. Mirrors the renderer's untrimmed
title lookup across both bare and pipe forms.

Regression test in wiki_links_test.go covers the exact scenario:
item titled " TASK-5 " (with whitespace), source body `[[ TASK-5 ]]`,
backlink resolves via the untrimmed ref→title fallback.

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).

* 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).

Refs: TASK-1594, PLAN-1593

* 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.

Verification:
- make check clean
- All TestWikiLinks_* pass

* 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.

* 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

make check clean.

* 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.

* 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.

* 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]])

* 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.
