fix(attachments): a HEIC embed is decided by what can be served and painted, not by an image/ prefix (BUG-2964)
A pure-Go build derives no HEIC thumbnail, and the byte endpoint SILENTLY serves the original when the requested variant is missing — so an editor that chose <img> on a MIME PREFIX handed the browser HEIC bytes, which Chrome and Firefox render as the broken-image icon. The server now says what it did: X-Pad-Attachment-Variant names what the BYTES are (a fallback still reports `original`), and X-Pad-Attachment-Derived names which variants EXIST, answered only on the no-variant path so the hot image path pays nothing. `none` is a sentinel rather than an empty value, because ABSENCE has to keep meaning "server predates this fix". The rule, in both renderers: embed as <img> iff THE VARIANT THIS RENDER WILL REQUEST exists, OR the browser paints the original. Not a prefix (the bug); not availability alone (the same build derives no AVIF thumbnail, and browsers decode AVIF). The second disjunct is a new fourth predicate beside display.ts's three, NOT canOpenInViewer — that one excludes image/svg+xml for active-content reasons, and an SVG inside an <img> runs no script, so reusing it would have flipped every existing SVG embed to a chip. Verified on a REAL HEIF against a pure-Go build, with a PNG positive control on the same instance: HEIF reads `none` and answers ?variant=thumb-md with 200 + Content-Type image/heif — the defect itself; PNG reads `thumb-sm,thumb-md` and answers with the actual thumbnail. Three counterfactuals and a negative control on the new TS/Go lock-step test, which replaces a lock-step that had been asserted in a comment only. Codex CLEAN after 3 rounds; rounds 1 and 2 each found a real defect in the fix (a per-variant fact collapsed to a boolean, and an async fact cached as durable). The share-link 404 is deliberately unchanged — that path serves variants only because the variant pipeline is the privacy boundary, and serving an original to an anonymous viewer would trade a broken image for an EXIF/GPS leak. The limitation is documented per surface beside the capabilities endpoint. Claude-Session: https://claude.ai/code/session_01Xk9M5UVPdc84xL5E1mZkm8 |

feat(web,server): render embedded image attachments on share pages via a variants-only byte endpoint (BUG-2389 2b, TASK-2637) (#1153)
Merged by lead on accepted infra cancellation, Dave-approved in chat (day-44). Evidence basis: E2E tests demonstrably pass at pinned SHA

fix(ci): gofmt + bump race-detector timeout to 30m (#299)
CI on main has been failing since the PLAN-866 attachment work
landed. Two independent issues:
1. gofmt failures (golangci-lint) — seven files in the attachments
path had trailing-comment alignment that gofmt wanted nudged a
column. Pure whitespace; ran `gofmt -w` across the affected
files. golangci-lint's gofmt linter caught it on every PR /
push since TASK-870 but we hadn't been watching those signals.
Files cleaned: internal/attachments/{fs_store_test,mime,
mime_test,processor_test}.go, internal/server/{
handlers_attachments_download_test,handlers_attachments_transform,
render/attachments_test}.go.
Local guard: `gofmt -l ./...` now exits clean.
2. Race-detector tests timed out at 20m on the GitHub-hosted runner.
Two contributors:
- PostgreSQL adds latency on every CREATE/DROP plus on the
bcrypt hash inside auth/bootstrap (~3s per call under -race
on the runner). Tests that bootstrap a fresh user (e.g.
TestSessionIPChange_*) pay the full cost each time.
- The PLAN-866 image-processing tests (thumbnail derivation,
rotate / crop transform) added ~2-3 minutes of decode/encode
work on top of the existing suite.
The previous "20m gives margin without papering over a hang"
comment was right at the time it was written; we now genuinely
need more headroom. Bumped to 30m on both the SQLite and
PostgreSQL race steps. Genuine deadlocks would still trip this
and produce the goroutine-dump panic — we just stop confusing
"slow but progressing" with "permanently hung".
Reference points before / after:
- TASK-875 main run #294: Go (PostgreSQL) finished in 17m48s ✓
- TASK-880 main run #298: Go (PostgreSQL) hit 20m timeout ✗
- Local: my new tests under -race add ~63s on a developer laptop
(TestThumbnails + TestTransform + TestProcessor combined).
Verification:
go test ./... — pass
go vet ./... — clean
gofmt -l (recursively) — clean

feat(attachments): markdown reference resolver for pad-attachment:UUID (TASK-874) (#291)
* feat(attachments): markdown reference resolver for pad-attachment:UUID (TASK-874)
Add the shared step that translates `pad-attachment:UUID` markdown
references into rendered HTML for image embeds, file chips, and missing
placeholders. Wired into the editor preview path; Go-side helpers seed
the future server-side rendering pipeline (export / shared item view).
TS side (`web/src/lib/markdown/attachments.ts`):
- Pure helpers: parseAttachmentHref, attachmentDownloadUrl, isImageMime,
formatAttachmentSize, renderAttachmentImage/Chip/Missing
- resolveAttachmentImage / resolveAttachmentLink for the marked hooks
- Image MIME → <img src=...?variant=thumb-md data-attachment-id=...>
- Non-image MIME (or link syntax) → file chip with download attribute
- Missing/deleted → "Missing attachment" placeholder span
`web/src/lib/utils/markdown.ts`:
- renderer.image override (defaulting to marked's standard image when
href is not pad-attachment:)
- renderer.link checks for pad-attachment: prefix before the existing
external/internal-link logic
- renderMarkdown gains an optional attachmentResolver parameter; the
resolver is threaded via a per-call module slot (synchronous render)
- DOMPurify allowlist extended with data-attachment-id, download,
width, height — ALLOW_DATA_ATTR stays false so only this single
data-* attribute slips through
Go side (`internal/server/render/attachments.go`):
- Mirror of the TS API so server-rendered output matches client output
byte-for-byte for the same input
- ResolveAttachmentReferences scans markdown source via regex,
skipping fenced code blocks (backtick + tilde), substitutes both
image and link forms
- Comprehensive table-driven tests (24 cases) covering: href parsing,
URL building, MIME detection, size formatting, image/chip/missing
rendering, escape safety against script-tag injection in alt /
filename / display text, fenced-code skip, tilde fences, title
suffix on link destinations, nil resolver pass-through, no false
positives on non-attachment URLs, deterministic round-trip
References are stored as opaque `pad-attachment:UUID` so a backend
migration (FS → S3) can rewrite storage_keys without touching item
content. See DOC-865 for the architecture.
Parent: PLAN-866 (Attachments Phase 1).
* fix(attachments): chip label double-escape + escaped-bracket lockstep per Codex review (round 1)
Two findings from the round-1 Codex review:
1. TS chip labels were double-escaped. renderer.link was passing the
parseInline(tokens) HTML output to resolveAttachmentLink, which feeds
it into renderAttachmentChip → escapeHtml. A label like
`[**Report**](pad-attachment:id)` rendered literal
`<strong>Report</strong>` instead of plain text. Switched
to the link token's raw `text` field; markdown emphasis inside chip
labels now degrades to literal markers (acceptable for filename-style
labels) and matches what the Go regex extracts.
2. Go regex didn't accept CommonMark `\]` / `\\` escapes inside link/image
labels, so `[Q1 \] report](pad-attachment:id)` resolved on the TS side
(marked handles escapes) but stayed literal on the Go side — breaking
the documented lock-step contract. Updated the regex to accept escaped
characters inside the alt/text capture, and added unescapeMarkdownText
to mirror marked's behavior of dropping the backslash before the label
reaches the render helpers.
Tests added: TestResolveAttachmentReferences_EscapedBrackets covers
image alt, link text, and combined backslash/bracket escapes;
TestUnescapeMarkdownText is the unit-level table for the unescape
helper (including dangling-backslash and non-punctuation pass-through).
