+QA3 narrow native runner passes3/0fail/0flaky/0skip, not CI qualification. Keep QA3 OPEN or blocked/deferred with exact unavailable failure-evidence reason; retain docs-only evidence+normal queue/durable status. No more speculative Firefox reruns/concurrency ramp.
+
+Claim QA4 after rereading newest RULE-CHANGES. Preserve own dirty/unlanded evidence before merge unstable. Actual-app bounded Chromium at360x800/390x844/1280x720: verify genuine dependency mirror/hash and actual app readiness, then open Upload through actual UI; measure document/client/scroll widths, component bounding rectangles and exact overflow source. Preserve strict width<=viewport as originally failing; no separate relaxed pass replacing it. Capture actual critical touch-target sizes/reachability, focus-visible/Tab containment+close-focus restore, horizontal scroll/zoom behavior as feasible; distinguish measured local/browser checks from real device/AA audit. Use source trace/computed style to identify culprit, tokens/classes/rules, before suggesting minimal CSS file scope. No speculative redesign or token/color changes.
+
+Investigation/source/scratch/unique evidence ONLY, no product/CSS/retained tests/helpers/config edits. Do not publish/seed real events or use real accounts/relays/signers/cloud/media. Use existing actual-app fixtures and verified genuine offline dependency mirror; no fake app substitute. Local mock relay/synthetic data only if needed; block other public HTTP/WS. If prep prevents actual boot, stop and report exact blocker before substituting.
+
+Exclusive bounded Chromium browser slot GRANTED for this baseline, announce START/.task and RELEASE with UTC/exact SHA/commands/check counts/resource cleanup. Preserve preview3000/peer resources, use own private server. No broad/full/build or product submit before dispatch resource grant. After first demonstrated culprit or hard blocker report to dispatch for independent reproduction and precise CSS ownership. All6 campaign priorities remain tracked; no product fix to Firefox inferred from local pass.

 ## Current assignment 2026-10-22: playback-qa-3 — Firefox deterministic CI failure
 
 Supersedes prior idle/QA2 scope below. Read current dispatch campaign brief, PROGRAM/RULE-CHANGES/KNOWN_ISSUES, harness and test integrity. Inspect own clean/unlanded state; fast-forward own branch safely to unstable, report SHA, claim QA3, send read/next-action. Interpreter reports run39536282396/job119013565277 failed Firefox at fb54cea3 while build/units/Chromium/visual passed; remote logs previously empty. This is reported evidence, not a diagnosed product failure. Inspect workflow/artifacts/read-only CI metadata if accessible; no credential disclosure/access, remote writes or workflow rerun. Identify failing step/assertion before smallest local deterministic reproduction, preserving first failure and natural exit. Do not assume known hydration flake is cause. Existing tests/helpers/config/product read-only until precise defect and dispatch ownership routing; scratch/new QA evidence only. Browser/expensive slot initially GRANTED for one narrow Firefox reproduction at a time, announce start in .task/mailbox and release promptly; no broad E2E/full npm test/build/normal product queue until separate slot. Other workers focused offline only. No retries/sleeps/weaker assertions/force exits/public fixture traffic; preserve preview3000 and peer servers. Report exact failure, command/counts/environment and unverified CI boundary. Mobile overflow/touch/focus is staged next after Firefox checkpoint; no CSS edits yet.
