Handoff: Coordinate current-head diagnosis of the saved two-frame assertion
Written 2026-10-08 08:33 UTC, sweep worker w5.
RE-VERIFY: Check https://github.com/CodexCoder21Organization/UrlResolver/pull/1203 with gh pr view for state, headRefOid and all checks. Verify branch heads with git ls-remote. Check the sweep UrlResolver-1203 lock before modifying the PR. Worker w4 currently owns that lock, CI and the remaining M1 carry work; w5 was restricted to read-only triage by its ownership note. The orchestrator makes all merge/close decisions.
Mission and current remaining work
The sweep user asked to work through open handoffs, close obsolete work, drive desirable PRs green and merged, skip disk-exhaustion steps and skip deploys. This worker may never merge or close a handoff/PR. The original lane was to carry eight review probes, rewrite the synchronous-state callback fixture, repair cleanup, run 5/5 plus isolated mutation gates and push tests only.
The old gate is mostly superseded: later carry commit https://github.com/CodexCoder21Organization/UrlResolver/commit/a72624f2dfea54bc34759d976cfe728c1de21c07 is an ancestor of live PR head955b7775ebfc3b3b62e6747504e2065aa4eaeadd. Later records show seven carried probes plus rewritten state each5/5 and all six isolated mutations failing seven target checks. No need to redo that entire gate as though the round-seven production head were still awaited. Main remains4fe061512ba91888439a2cf10608631bb99b6121, so this work has not merged.
The residual testProjectionTwoDeferredFramesApplyInRevisionOrder remains absent from live PR tests and explicitly open on its saved branch. The original failure was Expected [300,400], actual [300,300,400], at its exact list assertion. The test records the current state in every onInvalidated callback; that record alone cannot distinguish duplicate application from a different invalidation reading the same current value. A later lane ran the identical probe five times unchanged against production1004cec9, all passing. Its only preserved callback trace is a passing trace with two initial-snapshot invalidations, one replacement-snapshot invalidation and one invalidation per delta; no failing duplicate trace establishes the mechanism. The later lane deliberately retained the unresolved test separately, rather than weakening it or adding it to the PR.
Current projection source separates installation from notification drain (publishSnapshot, publishChange, drainInstalledNotifications) and uses Observable0.3.24, whereas the saved fixture declares0.3.22. Its README now explicitly allows establishment coalescing and notifications after installation. This is reason to reassess the current oracle carefully, not proof that the old duplicate was harmless. No reliable failing sequence or corrected oracle has been established. This handoff should remain focused on that residual diagnosis; it cannot be closed just because five later runs passed.

Next steps
- Re-verify current refs, checks and owner. Coordinate with the owner before restoring the saved probe to a diagnosis branch or changing the PR. The orchestrator must decide whether resolving this probe is a pre-merge gate.
- Restore the unchanged two-frame fixture from work/fx1203n-sixth-probes against the current candidate; reconcile its dependency version with production Observable0.3.24 without changing assertions or bounds. Capture public callback and real transport frame ordering in a reliably failing sequence (near100%, never below50%) and distinguish actual application from current-value invalidation. Neither five passing runs nor a passing callback trace resolves the older failure.
- Only after the mechanism is established, fix the correct layer or explicitly refute the obsolete oracle with deterministic public-API evidence; do not deduplicate values, weaken assertions, lower iterations or raise timeouts. Finish the focused mutation/regression gates if the probe is retained. Current PR owner coordinates changes and CI; no duplicate watcher.
- Preserve all new work on remote refs and report a fresh verdict. No enqueue, merge, deploy, restart or automatic completion.

Tests use scripts/test.bash --local --test <explicit-selector> --log <outside-repo>.xml; custom tests/test success XML must be checked, not only process exit. No fresh test/build was run by w5; all cited test counts are earlier remote proof records. No production code, test, README, PR description or dependency declaration changed by w5. No merge, queue, publication, deploy or restart occurred. No binary outputs created. All tracked clone/search/push commands finished; no w5 watcher or test process remains. The evidence branch is clean and pushed.
