fix(web): archived thread links open the conversation#23278

Problem

Opening an archived thread through its URL redirects the web client to a new draft instead of showing its conversation. This also affects existing relationship and PR-linked thread destinations, which use the same route.

Change

Allow loaded, nondeleted archived-thread detail through the route guard. The chat already supports rendering this detail without an active-shell entry. Missing and deleted threads retain their existing rejection behavior. Add a route regression test and a synthetic fixture seed for rebuilding the captured state.

Scope and approval

Fixes #16443 GitCafe: https://git.cafe/pingdotgg/t3code/issues/16443 Triaged bug via the automated issue flow: #16443.

Verification

Red regression: 1 failed, 12 passed; the archived-link case expected ready and received missing. Failure transcript.
Final merged head f00201b30c: route suite 13/13 passed; targeted lint passed; web typecheck (tsc-rs --noEmit -p apps/web/tsconfig.json), fixture syntax and diff whitespace checks passed. Both initial independent source reviews returned MERGE; final review reconfirms the unchanged route behavior and corrected fixture guard. Proof audit confirmed 57 capture hashes and all 10 published pixel comparisons, but returned INSUFFICIENT for the incomplete matrix and missing fresh rebuild.
Captures run against real isolated web development state on Ubuntu Chromium, DPR 2. Desktop viewport 1440×900, responsive web 390×844, light/dark. Evidence index, recordings, timestamps, environment and full gap list.

The committed-seed direct URL pair below shows baseline rejection and the fixed archived conversation. Recordings begin before navigation. Baseline runtime is a12d6ed942; fixed runtime is d7427515fe with fixture capture at f4f56588d3. Later commits move the fixture, canonicalize its live-home guard, and merge main; these are historical captures, not fresh captures of the final merged head.

Fixture / viewport / theme	Before	After	Diff0 (×8, any channel >0)	DiffT (any channel >16/255)
Archived URL / 1440×900 / dark	Before: archived URL redirects to a draft	After: archived URL displays the conversation	Amplified zero-threshold difference	Threshold-16 difference
Build	a12d6ed942	f4f56588d3	Same pair	Same pair
Navigation recording	Before	After	—	—

Visible differences beyond the restored conversation include panel preferences, relative sidebar ages, checkout counters and provider status indicators. No masks were applied; the pair does not establish pixel-identical surrounding state.

A fresh final-head browser attempt reached sandbox pairing, then the preview session and development server disappeared across a runtime restart. Recovery returned ERR_CONNECTION_REFUSED on the development origin. No fresh success capture is claimed.

Unverified: full matrix acceptance, final-head recapture, cold responsive conversation visibility, PR-palette destination selection, cold relationship discovery, Back/Forward, reconnect/error recovery, archived-only environment and lifecycle controls. Missing/deleted behavior is unit-tested; integrated negative controls are incomplete. Electron/custom-link dispatch and remote/relay/tunnel modes were not verified. Native mobile does not use the changed web route. The evidence index lists every attempted row and gap; this PR does not claim a complete proof-audit pass.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — The route change is a small, tested fix that lets archived thread links render without altering deleted-thread handling, and the added seed script is isolated test tooling. Unresolved external review findings nevertheless identify concrete webhook filtering/template correctness concerns, so human review is warranted.

Notes:

All code in this push has already been reviewed. Approvability was decided on eligibility alone.

📝 Walkthrough

The thread route now renders loaded archived thread details as ready. It continues to treat missing details as loading and details marked deleted as missing. Tests cover these outcomes, and a fixture seeder creates archived and active threads with conversation data.

Changes: Archived thread routes

Layer / File(s)	Summary
Archived thread route state `apps/web/src/threadRoutes.ts`, `apps/web/src/threadRoutes.test.ts`	The resolver returns `missing` only when thread detail has a non-null `deletedAt`. Tests cover archived, missing, and deleted thread outcomes.
Archived thread fixture seeder `apps/web/test/fixtures/archived-thread-links/seed.mjs`	The seeder checks that the database is isolated and migrated, backs it up, and transactionally creates archived and active threads with completed conversation data. It reports the backup path and fixture route.

Explanation

Issue #16443 requires an archived thread URL to show its conversation. resolveThreadRouteRenderState now returns ready when loaded detail is nondeleted, even when the active shell omits the thread. It returns missing for a deleted detail or a confirmed missing detail. threadRoutes.test.ts covers loading, archived/nondeleted detail, missing, and deleted outcomes. The fixture seed supports the archived-link reproduction.

test(web): fixture guard canonicalizes the live T3 home5e9cd23
Merge remote-tracking branch 'origin/main' into fix/issue-16443f00201b

JJulius Marminge5d ago

The current f00201b30c diff contains only the archived route, its regression test, and the fixture. The unrelated webhook commit came from the earlier main tip and disappeared after main was force-updated; refreshing main removed those changes from this PR. The two webhook findings therefore no longer apply to this diff.

The fixture guard finding was valid: 5e9cd235ad canonicalizes the shared home and uses a separator-aware relative-path check. Real-script temporary-HOME checks reject the live directory, descendants, ..foo descendants, and symlink aliases, while allowing parents and siblings. Native Windows was not tested; Windows path semantics were checked with Node’s Windows path helpers.
