View on GitHubTwo-way sync enabledPR last imported 16h ago

Problem

Answering an async question after a queued turn completes persists the answer and starts another run, but hides its user message from the timeline. The later reply appears without its input; only the older question card shows the answer.

Change

Fold an async answer into its question card only when both belong to the same run. Apply that rule to the web timeline, native mobile feed and its cache, and SQL/memory Find in Thread, so later-run answers remain visible and searchable. Keep the older card's answer history. Include sanitized, replayable capture fixtures.

Scope and approval

Fixes #15873 GitCafe: https://git.cafe/pingdotgg/t3code/issues/15873 Triaged bug via the automated issue flow: #15873. One underlying folding defect across the clients and search. No schema or provider protocol changes.

Verification

CI blocked at current head: GitCafe reports 13 failed and 22 successful checks at 31d3a20a19. Mirrored check summaries/run IDs are null and Cafe exposes no corresponding CI/Actions runs or diagnostic logs. Two agents verified the gap. Failure attribution is undetermined; this is not a green CI result. No speculative code changes or reruns were made.

Seeder follow-up 31d3a20a19 addresses all three CodeRabbit findings: synchronize C row timestamps, normalize retained provider/checkpoint run ordinals, and restrict destinations to the script checkout’s disposable .t3 directory before opening SQLite (including symlink escapes/live-home rejection). The lead reran the validator: five fixture/idempotence checks pass; 40 corruptions and nine unsafe paths are rejected. Exactly 13 stored metadata fields change; identities, text, payload timestamps and positions remain unchanged. Field-by-field report. Production files are unchanged; the 105-test result below is from the preceding implementation head. Captures retain their original SHA/database scope and were not repeated with corrected metadata.

Post-merge focused suite: 105/105 passed (49 web timeline, 37 mobile feed, 19 server Find), using node_modules/.bin/vp test run apps/web/src/session-logic.test.ts apps/mobile/src/lib/threadActivity.test.ts apps/server/src/orchestration-v2/ThreadFind.test.ts. Targeted lint on the six changed TypeScript files and git diff --check passed. Prior scoped typechecks passed before integration; no repo-wide checks run.

Merged main 8acbefefc5 with a merge commit 3738c10463. All three changed production source files are byte-identical to the captured AFTER checkout; captures were not repeated on this merge. Main also brings unrelated mobile/layout, forge and release changes, so the evidence remains scoped to the recorded SHA.

Red-first regressions failed on the missing answer in web full/incremental projection, mobile fresh/cached feeds, and SQL/memory Find. The original real-app reproduction is recorded in the issue comment. The lead independently verified exactly one late-answer bubble between the queued reply and its acknowledgement, and real Find returns 1/1 with the answer highlighted.

Final round (3/3): both isolated reviewers found no production defect and returned FIX_FIRST. Codex retained the active/mounted/native evidence objection. Opus requested removing evidence fixtures under the generic PR-assets rule; the explicit task requirement to commit the seeding script and fixture data takes precedence, so they remain. Fixture metadata inconsistencies identified during review were corrected in the bot follow-up below; these stopped snapshots certify settled rendering only, not lifecycle or subsequent dispatch. Read the Codex review, Opus review, and proof audit pass 2. Proof verdict: INSUFFICIENT for hot transitions, active steering, complete Find/control interactions, native clients and full-framebuffer wide stills. All 30 pair comparisons and 120 hashes passed; independently rebuilt G and Find narrow/light captures were byte-identical (zero pixel delta).

Not merge-ready on evidence alone. Native iOS, Android and Electron remain unverified; hot cache/answer-delivery transitions and full-framebuffer wide PNG proof are missing. Recording durations were verified with decoded browser metadata; narration uses wall-clock action-initiation offsets rather than certified media seek timestamps. See the explicit coverage gaps below.

Environment and reproduction

Worktree /home/ubuntu/wt/issue-15873, restored to branch fix/issue-15873 at 7dcb809db8. Browser is product-native T3 server preview, own tab tab_l_6e549cef-3988-4dbf-afd5-b7128d4b53ce. Chrome 154 on Linux x86_64; devicePixelRatio=2, zoom 1, loaded default fonts, interface 16px/prompt 14px/code 13px, default light/dark palettes. Browser language en-US and timezone UTC were verified; rendered messages show “yesterday at 11:xx PM”. Process Node v24.21.0 used identically on both SHAs; BEFORE contains the new Node26 pin, so this does not validate the new release toolchain.

Viewport grid: 1440×1000 and 390×844 CSS px. Narrow output is web, not native mobile. Saved narrow PNG is 780×1688. The snapshot tool internally caps wide output at 1280px, producing 1280×889 from 1440×1000 at DPR2. PNGs here are the exact original tool files, with no subsequent scaling, cropping, alignment or masking. Thus wide PNG diffs are not full-framebuffer proof. Original MP4 recordings preserve 2880×2000 wide or780×1688 narrow; they are compressed/lossy and not used for pixel counts. No source/MCP modification or alternate automation used to bypass the cap.

Fixed presentation Date: epoch 1792627200000, 2026-10-22T00:00:00.000Z; JS Date constructor/Date.now overridden through preview_evaluate after hydration, while requestAnimationFrame/timers continue normally. Fixture timestamps are fixed. This is presentation-clock control, not a frozen provider/backend clock. All captured rows are completed snapshots.

Isolated runtime home .t3/capture, database .t3/capture/userdata/statev2.sqlite. Schema copied/migrated from disposable worktree state; orchestration, projection and auth rows cleared before seeding. Never opened installed ~/.t3/userdata database read-write. Product recovery stopped five ready fixture sessions and resumed zero runs/effects. Original .t3/userdata/statev2.sqlite preserved. AFTER used PATH="$PWD/node_modules/.bin:$PATH" vp run dev --home-dir "$PWD/.t3/capture"; BEFORE web used same runner and backend directly used node apps/server/src/bin.ts --base-dir "$PWD/.t3/capture" --port 16526 --dev-url http://localhost:8486 --no-browser. Actual web/server ports8486/16526. No VITE_HTTP_URL or VITE_WS_URL set.

Reproduction: select the product SHA; create a clean migrated disposable home, stop server, run the committed seed.py with python3 -B, then start on that home. Authenticate with a newly minted private pairing URL (none published). Route first segment is environment ID, not project ID; use the environment's current ID and the seeder's printed thread ID. The old /tmp/issue-15873-capture/routes.json has project IDs in its first segment and is only a fixture identity map, not valid direct URLs. Actual captured environment ID and routes are recorded per checkpoint in the manifest. Hide main sidebar and thread details, leave terminal/right panels closed, blur composer, move pointer to(1,1), wait for document.fonts.ready and projection acknowledgment. For standard stills scroll .messages-timeline-scroll to end for six animation frames; G-history uses scrollTop0. Snapshot state stores actual offsets, height and scroll extent. Wide G/A/C/L fit without scrolling; S crosses the end boundary after insertion and scrolls11CSS px, so its earlier content shifts upward accordingly. Long reveal scrolls to the end of the expanded body. Find action attempts begin from history top using real Control+F, input, Enter/Shift+Enter and Escape; the recording audit below limits which results are visible. Later fixture navigation uses production TanStack router through preview_evaluate; original wide-light clip also includes a cold A reload/reconnect.

Fixtures G/A/C/L and settled-S are rendering replays, not fresh provider sessions. G preserves genuine three-run structure; A/L remove intermediate run and renumber later run/positions; C moves synthetic answer to its question run before its final acknowledgment. Native item identities are distinct across fixtures to avoid global primary-key overwrites. Seeder validates retained run/node references, unique timeline ordinals, message/timeline text/run agreement, and schema columns were checked against the migrated DB. All generated runs are completed. Checkpoint refs are synthetic and do not point at actual checkpoint Git objects; revert actions are not certified. Direct projections do not create coherent business-event histories; no provider/event lifecycle claim follows.

Comparison method

For every pair, decode original PNG to RGB; channel delta is absolute integer difference. Diff0 image is min(delta×8,255) on black. Count a Diff0 changed pixel iff any RGB channel differs at all. DiffT uses a fixed max-channel delta>16/255 criterion, painted magenta on black; no ignored regions. Threshold chosen before comparison; no tolerance tuning. Counts and SHA256 hashes are retained in comparisons.json; rerun python3 compare.py after downloading/pointing the manifest to originals. No unexplained-zero or “nothing else changed” claim is made. C's exact equality applies only to the four captured collapsed settled control states.

30 pairs:20 timeline,4 Find,4 expanded-L comparisons,2 G-history. For expanded-L, BEFORE aliases its corresponding absent-bubble baseline; there is no BEFORE expand control. Eight recordings below supplement stills; they do not prove hot projection insertion, active steering or unexecuted controls.

Captured sequences and pairs

Recording audit correction: narration below lists tool wall-clock action attempts, not certified media seek times. The recordings do not establish every narrated outcome. AFTER/390/light shows next (PTS 25.412→25.503) and previous (25.814), but no closed Find frame. AFTER/1440/dark ends while the multiple query is searching; BEFORE/1440/light and dark end at the exclusive query's 0/0 state. AFTER/1440/light ends with the unrelated query searching. BEFORE/390/dark does show Find closed at PTS 23.924. Complete per-cell navigation/close outcomes remain unverified. These recordings certify only their observable settled states and interactions.

Clip timestamps below are wall-clock offsets from recording_start, measured from tool step timestamps, rounded to0.01s. They identify action initiation; recorded encoders may omit idle frames and the original wide-light reconnect interrupts automation. Do not treat a selected still as a provider transition. Each checkpoint also retains actual UTC capture time in the manifest. Ordered narration appears before each group's comparison table.

Approvability

Verdict: Approved at 31d3a20

Macroscope's review found this PR approvable — This is a focused cross-client bug fix that preserves same-run answer folding while making later-run async answers visible and searchable, with targeted web, mobile/cache, SQL, and memory tests. The large added fixture data is limited to manual development replay and does not affect the production request path.

📝 Walkthrough

Mobile and web timeline projections and server thread search now associate asynchronous answer message IDs with run IDs. This preserves messages from earlier runs when an answer is handled in a later run. Tests cover these projections and search paths. The change also adds replay fixtures and a seeding script.

Changes: Asynchronous answer run handling

Layer / File(s)	Summary
Run-aware timeline projections `apps/mobile/src/lib/threadActivity.ts`, `apps/mobile/src/lib/threadActivity.test.ts`, `apps/web/src/session-logic.ts`, `apps/web/src/session-logic.test.ts`	Mobile and web projections associate answer message IDs with the request’s run ID. They skip a matching user message only when its run ID also matches. Tests cover late answers in full and incremental timelines, and in cached and uncached feeds.
Run-aware thread search `apps/server/src/orchestration-v2/ThreadFind.ts`, `apps/server/src/orchestration-v2/ThreadFind.test.ts`	In-memory and SQLite-backed search use run IDs when filtering answered requests. Tests verify that searches find the answer handled in a later run.
Issue replay fixtures `scripts/fixtures/issue-15873/*`	Adds a three-run runtime snapshot, a script that creates and validates five fixture variations, and documentation for fixture setup and use.

Explanation

The pull request description includes all required sections: Problem, Change, Scope and approval, and Verification. It clearly describes the bug, affected components, linked issue, implementation scope, focused test results, environment, reproduction steps, and known verification gaps. The description also identifies that native clients, hot transitions, and full-framebuffer evidence remain unverified.

fix(fixtures): keep async answer replay metadata consistent31d3a20

JJulius Marminge3d ago

Addressed all three seeder findings in 31d3a20a19: row timestamps now match payloads, provider/checkpoint ordinals match retained runs, and database paths must resolve inside this checkout’s .t3 before SQLite opens.

All five fixture/idempotence checks pass; 40 deliberate corruptions and nine unsafe paths are rejected. Validation and exact field changes. Production code and original evidence artifacts are unchanged; captures retain their recorded SHA scope.

At 31d3a20a19, GitCafe reports 13 failed and 22 successful checks. Build/typecheck, lint and test failure logs are unavailable: cafe ci status reports no runs; both Actions/CI run lists are empty; mirrored checks have null summaries and run IDs. Two agents independently confirmed the API gap.

Failure attribution remains undetermined. No code changes or reruns were made from this investigation. This PR remains blocked on diagnostic logs, in addition to its documented verification gaps.
