Confirm the attempt's own job notification/peak or hard-limit peak evidence before latching a Windows memory packet. A nested job's lower cap is not the attempt cap; packet type/key alone was insufficient. Share the predicate with the holder to preserve MR-17 semantics and safely ignore queued packets after disposal. Keep existing nonzero normalization while making detail explicit: own-job evidence accompanies the exit, allocation refusal is not proven. Align contract comments. Design#37 merged first as973934c (full Windows3/12 s,Linux3/44 s). No enum/RPC/schema/package migration,enforcement feature,credential operation or later-feature activation.

First complete Windows candidate gate fa6f836 failed in win-ci: SchedulerTests.TwoSessionsShareAdmissionsEquallyOnWindows, first12 starts6:6 but measured slot-time share65.3948% outside original40–60%;322 total,283 pass,38 skips,1 failure. Subsequent schema/publish/native/bench/package/exclusive/startup steps were not run; wrapper1/summary false retained (20261026-041700-fa6f83622c8a-win). Diagnosis: FairnessAsync uses300 ms holds but measures admission-to-finish slot occupancy including launch/finalization. The comment claiming independence from below-normal startup was false; both wrappers lacked isolation despite AGENTS requiring exclusive+DisableParallelization for timing/CPU-share-sensitive tests. A single matched fa6f836 idle/isolated diagnostic, with no competing Windows build/test, passed unchanged assertions:6:6 starts,50.5% share,10.048 s. Necessary gate-fixture repair in this PR marks both OS cases exclusive and corrects the comment; no scheduler algorithm, task duration/count,40–60% or5–7 starts assertion, or180 s timeout changed. New head needs both complete native source gates; old fa6f836 Linux leg is allowed to finish cleanly, never used as the new-head gate. Source memory author checks already passed at fa6f836; their code is unchanged by this test-isolation-only delta. Retain all failed/partial/diagnostic evidence, do not blindly replay or weaken validation. Owner's latest instruction: finish MR-18 and records then STOP; do not begin MR-19.

[deku2026]

Latest owner instruction supersedes the earlier automatic continuation: finish MR-18 (including all final native gates, actual merges, maintenance list/CLI ledger and stop handoff), then STOP; do not begin MR-19. Final current head15d6717144468ce0be615e8538f858d29b0fed7d/treefed15ef1b4251c08d8bd48afcfe32b2530570e06 differs from fa6f836 only in SchedulerTests timing-isolation attributes/comment; git diff fa6f836..15d6717 -- src tools eng is empty. Initial memory-code authors remain distinct fa6f836 evidence, not final-head required statuses. New-head Windows format/build zero warnings/errors25.83 s, isolated fairness and Repository72/72 passed; both complete native final-head profiles are required afresh. Windows final3 starts now; old Linux fa6f836 final2 is allowed to finish and clean its private units before starting15d6717 on that host. Earlier malformed compound launch left a partial fa6f836 Linux log/controller gone with no summary/exit; native process/PID inspection confirmed no residual compile/test before standalone-nohup full restart. No manual status copy, concurrent same-host formal run, tolerance/timeout reduction or skipped assertion.

New final15d6717 full Windows final3 already running; native Linux final3 now starts with no competing same-host build/test. Both new exact-head statuses required; no source/runtime code changed betweenfa and15d, only existing-policy timing isolation, but no old-head status reused. Stop after MR-18 records under latest owner instruction, MR-19 unstarted.

Direct self-review by OpenAI Codex alone under explicit user instruction; no independent reviewer claimed. Reviewed full memory-code/contract/test diff atfa6f836 and final SchedulerTests-only delta at current15d6717144468ce0be615e8538f858d29b0fed7d/treefed15ef1b4251c08d8bd48afcfe32b2530570e06, base852d23d8b4daca78cef509cb7a6925b18795b6b1, against merged Design#37/973934c. No unresolved code findings; final exact-head host statuses remain required. Shared own-job predicate preserves MR-17 strict notification/legacy hard comparisons; packet type/key alone never latches a foreign lower limit. Latched true avoids repeat native queries; expected disposed-handle races fail closed without swallowing non-disposal Win32 faults. Detail says evidence/own job/nonzero and unproven refusal, not causal allocation failure. Internal observer/borrowed port are read-only provenance/composition seams, default-null observer; test uses real jobs, shared real IOCP and actual kernel hard packet, never manually posts/calls handler or fabricates counters. Own aggregate stays below own cap; an actual packet is mandatory. Default-forwarding prerequisite timeouts are retained separately, no general forwarding claim. New detail assertions strengthen existing real NodeHost/holder cases; zero/non-crossing/raw/effect guards remain. Necessary final-gate isolation fix follows existing timing-sensitive policy, preserves all fairness values/loads/deadlines/coverage, changes no scheduler/source/runtime/eng code. All private process/job/port lifetimes and fixture cleanup reviewed. Existing author/probe failures and old-head Linux run cannot substitute for the final15d6717 full Windows/Linux gates. Finish current MR-18 records then STOP; no MR-19 work.

Final MR-18 gate and direct review at pushed head 15d6717144468ce0be615e8538f858d29b0fed7d, tree fed15ef1b4251c08d8bd48afcfe32b2530570e06, base/main 852d23d8b4daca78cef509cb7a6925b18795b6b1.

Both complete native full profiles passed; all 29 individual summary results, both wrapper exits 0, and the engine-reported exact-head GitHub statuses were read. Windows: 13 steps/1140 s, summary 20261026-043314-15d671714446-win; Linux: 16 steps/1382 s, summary 20261026-124013-15d671714446-linux. Both include JIT/native exclusive and startup gates; native publish/closed-loop/bench/package, repository guards, Linux format/real-OS checks and secret scan passed. Owner-hosted checks and the real OS secret-store tier are skipped as required. No OS-store opt-in, gate weakening or copied old-head status.

Direct final diff review remains as recorded in #issuecomment-6408391894: own-job accounting/actual thresholds gate packets, MR-17 comparisons remain shared and unchanged, the detail preserves allocation-refusal uncertainty, disposal is guarded, and test provenance comes from real kernel packets/handles. The final SchedulerTests-only delta applies the existing timing isolation policy; all fairness bounds, holds, counts and timeouts remain. No unresolved finding. OpenAI Codex worked/reviewed alone under the owner's instruction; no independent reviewer or other agent is claimed.

The failed fa6f836 Windows timing gate, initial incomplete Linux controller run, and old-head Linux success remain separate evidence and do not gate this commit. Design#37 already merged first as 973934c658f62967be4b6cc40d0526d877ee4383. After source merge, append Plan CLI ledger notes and validate/merge the maintenance list, detailed evidence and stop handoff in their own PR. The owner's latest instruction is to finish MR-18 then STOP; MR-19 remains unstarted. MR-16 remains blocked and MR-07/11/15 remain deferred.
