Disposition: RETAIN_OPEN. The six-hour follow-up is handled with accepted saved evidence and the original owner's remaining obligation.

Priority: P2
Classification: product
Scope: global
QA-Owner: mausbot-front
QA-Next: Original Front retains the historical frame/page and separate adjacent-drag mechanisms. Consume only new saved natural failure-time evidence through the existing diagnostic path; a causal repair needs a demonstrated mechanism and independent delta review.

QA-Blocker: The historical wrong-aspect frame/page mechanism and the distinct adjacent-drag mechanism remain UNKNOWN. The new natural positive does not establish a causal repair or shared cause.

The exact panel/page/frame-ratio case passed in 4060.109 ms in browser-driver job 132368743004; the stream-v2 file passed 12/12. Its full-matrix duplicate in shard 8 was skipped. The test blob equals the already accepted main4bd diagnostic blob and the later main692 blob. Existing PR758/PR764 source acceptances and integration remain complete.

The original independent Reviewer2 has accepted this bounded saved-evidence applicability review for source run 43566863510:1, tested ab39932010fc01536112baf4c7a18378623358b1 / tree 19e424d5399acf713c1929e45a70346a27158c1e, and its own reporter 43573522957:1. All 17 selected jobs succeeded; executionComplete, deliveryComplete and testsPassed are true, with no missing jobs or findings. The reporter workflow revision 995c31d8b82652be71ffc7d19ef6b702d4a8e8f3 is distinct from the tested source.

The later incomplete main692 report has the exact key positive; its report limitations and all historical frame/drag failures remain. This older successful run does not replace the newer main692 recurrence dispositions. Existing reporter retry rules apply; absent raw retryCount is not a universal zero-retry claim. No new raw-retry gate is added.

Independent applicability receipt SHA256: 959bdf3107c5bd6d059cc977fd62403afd2d5d5df10f2514125ef123920eabdd. All original causes, failures, dates, missed checkpoints and prior accepted scopes remain recorded. The next date is an advisory evidence follow-up, not a closure promise. No new test run, source change, dependency mutation or live App action was used for this disposition.

QA-Disposition-Evidence: #53 (comment)

The exact real-Chrome driver case passed in 5323.382 ms; its driver file passed 12/12. The matching matrix entry was skipped and is not a second positive. Accepted PR758 and PR764 diagnostic source is integrated.

The original independent Reviewer2 accepted this scope in receipt SHA256 8476a8d6bcca05acd18abb272636fc19fbcedf98aa363089fbad0969124e2214. Natural source run 43553350282:1 tested 4bd782f9f398aa66feeaaf569fe64e45b1e19001 / tree 253c3442a46149cfc47c895a1bb632cb332277e4; its own reporter 43558998085:1 records all 17 selected jobs successful, executionComplete=true, deliveryComplete=true and testsPassed=true, with no missing jobs or findings. The reporter workflow revision is separate from the tested source.

All historical failures, original advisory dates, previous evidence and causes remain recorded below. Earlier running/missing-result/source-review flags are historical snapshots and are superseded by this disposition.

Evidence is accepted under the existing reporter retry rules; absent raw retryCount is not a blanket zero-retry claim. This verifies the stated scope on the tested revision, not newer main or native/App acceptance.

Current disposition: RETAIN OPEN; source integration and incident verification remain distinct.

The new scheduled ad9 report is delivered and execution-complete with failed tests elsewhere; that source predates these diagnostic integrations. Its positive panel key is scoped evidence, not a reconstruction of the original failure. The original incident remains OPEN.

QA-Assignment-Evidence: #53 (comment)

Weekend execution is now assigned and started, superseding the earlier saved-only follow-up limit. Original Front has checked the exact a2d8fc8 source, current validation policy and original evidence. The first candidate is limited to the exact real-browser fixture and a directly required test helper unless observation establishes a production defect. Use one worker and one bounded observation, retain the first result and the original 15-second behavior contract, and avoid automatic replay. The existing verified label is retained as historical execution evidence, not a closure decision.

The new execution authorization supersedes only earlier saved-only action limits. Original failures, prior verdicts and missed checkpoints remain below. Independent review, current-head required CI, applicable holds and post-integration verification still govern merge and closure.

Current disposition: RETAIN_OPEN; this bounded follow-up is complete.

Same original Reviewer2 accepted the bounded a2d saved-evidence applicability (canonical receipt SHA256 dd5d3db7f4cde307af4c167f3a15a83d830906f5c8cd2149d5e101b944b3d0bb). The prior accepted diagnosis and review carry; the disposition remains RETAIN_OPEN.

The bounded a2d applicability assessment is complete. The exact Darwin #53 panel/frame key appears once in passed and not in findings in the delivered a2d own report. This adds a scoped reported positive; it supplies no original failure-time frame/layout metrics or causal repair. RETAIN OPEN, P2/product/global, owner mausbot-front, cause UNKNOWN. The completed prior diagnosis and original failure record remain; no new test, build or App work is assigned. Exact key: 58a8577fbb2ccfac5ffcf5c9. The report records deliveryComplete=true, executionComplete=false and testsPassed=false, with 14 successful jobs, two failed jobs and one cancelled job. This is not whole-QA acceptance. No new raw retry-proof gate is assigned.

Prior failure epochs, accepted work and missed checkpoints remain in the history below and the linked dispositions. This checkpoint does not assign a duplicate investigation, workflow or App action.

Current disposition: OPEN; bounded owner evidence and independent review are complete.

QA-Blocker: The original wrong-aspect frame timeout still lacks synchronized failure-time source/order and layout metrics. A later exact-case pass does not explain that failure or establish a source repair.
QA-Evidence: https://github.com/MashellHan/mymausbot/actions/runs/43375765014 ; own reporter https://github.com/MashellHan/mymausbot/actions/runs/43385090279 ; original failure https://github.com/MashellHan/mymausbot/actions/runs/42191354410

The same original Reviewer2 accepted this saved-evidence delta and concluded RETAIN_OPEN. The bounded assessment is complete; applicable repair/verification obligations remain.

The new source-bound 6e8 main report 43375765014:1, delivered by own reporter 43385090279:1, contains exact resize-case key 58a8577fbb2ccfac5ffcf5c9 once in passed and no finding for it. It adds a scoped reported positive while the prior 6216-ms selected local pass and 131-ms transient recovery remain separately qualified. None supplies contemporaneous metrics from the original 15000-ms failure.

Keep the zero-selected first local invocation, hosted/local environment differences and earlier positives. The full report has complete execution/delivery but separate failures; no new frame metrics, raw duration or blanket per-test zero-retry evidence is claimed.

Original failed epochs, prior accepted source and reviews, platform obligations and missed dates remain preserved. The next date is an advisory evidence follow-up under the existing unresolved-work cadence, not a new scheduler or execution request.

First bounded disposition after the reviewed PR #749 hourly runtime adoption.

On pinned failing source 1fa0d9655b56e1c24acaabd288d21dfde7da972d, one isolated macOS selected case with Chrome for Testing 156.0.8078.80 passed in 6216 ms (1 passed, 10 skipped, no retries). The first invocation selected zero tests because OMB_VITEST_E2E=host excluded the file; that invocation is not a pass and remains preserved.

The observed transient 1829x2000 screencast reached the 1067x2000 target within 131 ms. It does not explain the original CI result remaining 1757x2000 for 15000 ms. Layout/window reads were after close, so contemporaneous timeout metrics and effective caps remain missing. Local macOS/Node also differ from the original hosted environment. No harmless-flake, causal repair or closure claim follows.

The independent fail/pass comparison remains pending diagnosis, not eligible for closure. The original narrow/tall JPEG failure and later exact-case success retain their separate provenance. No source repair is justified yet. Front remains the sole App delivery owner; this diagnostic starts after that priority handoff.

Independent review remains owned by mausbot-review. The next timestamp is an evidence checkpoint, not a promised repair completion. This handoff does not authorize or change the live App.

Independent Reviewer disposition (2026-11-10): keep this original issue open. Retain contemporaneous frame source/order, CSS/DPR, layout/window state and screencast caps on an actual recurrence; later passing observations do not explain the original 15-second failure. The source-bound 42803974434:1 / 6d7b31f report and all original failures and later positives remain distinct evidence; qa:verified alone does not authorize closure. The existing owner retains this work after the active focused repair handoff. No duplicate test run, new issue or live operation is requested.
