Current focus

State at 2026-10-11 00:55 UTC: Handoff 5 (the coverage unknowns) is done locally on ai/coverage-unknowns, from origin/master 6696f68; nothing is pushed. The report is Tests/Coverage/Quality-Gate-Unknowns-2026-10-10.md with nine CSV tables. rc7 (fa0701b) was measured at 3,198/3,649 sequence points (87.64%); the live suite (first lab, three matrix cells) and the unit suite on a domain member add only 9 sequence and 4 explicit branch points, all of fdd7a8b. Two tr-TR defects are fixed test-first (419cfb3, an identity compared with a name; 0028ccd, fbe0289, 8a625c8, Get-ChildItem2 -Filter, found by the independent review), 79 It blocks in four files are added (final commit 61e936e, built once at 8a625c8: 1,459 cases per configuration, 3,258/3,664 points, 88.92%; the matrix suite passes on Windows Server 2019, 2022, 2025 and Windows 11 in 16 configurations), and a defect is open (hard-link names under a root that is not the volume root). The maintainer decides whether the fixes and the tests enter a new candidate.

State at 2026-10-10 15:45 UTC: the maintainer integrated the release-gate stack into master (6dd799f, CI green): #116 (rc7, 8a6be9f), #120 (bdb9981; it replaced #117, which GitHub closed unmerged when the branch deletion after #116 removed its base, see Decision 15), #118 (03bef2c, handoff 1, the paths), #119 (fa0701b, handoff 2, the operating-system matrix), and #121 (the Memory Bank). He tagged fa0701b as 5.0.0-rc7 at about 12:20Z, and rc7 is published (Gallery 12:30:57Z, GitHub 12:31:09Z); 4.2.6 stays the stable Gallery version. rc7 contains the Phase 2 behavior changes, the path tests and fixes, and the three module fixes of the matrix (962887a, fdd7a8b). The published rc7 passed its lab acceptance (gate 3) on the same day, in the matrix and in the first lab, with the counts of the final local candidate (record Tests/Lab/Acceptance-2026-10-10-published-rc7.md). Stable 5.0.0 stays gated (Decision 21).

The maintainer asked on 2026-10-09 at 21:21 UTC to continue with the release-gate handoffs and to decide and report later. The agent's decisions are D1 to D47 in decisions-night-2026-10-09.md of the session files. Decisions 22 (Phase 2), 23 (the #34 dossier), and 24 (the matrix) are proposed: the agent confirmed Decision 22 under the delegation, and neither that nor any risk acceptance is the maintainer's.

Evidence

• rc6 Release run 37839669028, attempt 2, succeeded; GitHub prerelease with zip appeared 2026-10-09 07:01:34 UTC. The first attempt proves HTTP 409 after Gallery publication, not the earlier assumed retry chronology.
• Integration on 2026-10-10 (UTC): #116 merged 09:10, #117 closed unmerged 09:10:16 (events base_ref_deleted, closed), #120 merged 10:50, #118 11:12, #119 11:28, head branches deleted 11:34, CI on master at fa0701b green 11:40. A git merge-tree simulation of the chain was conflict-free and ended in the tree of the matrix branch.
• rc7 on 2026-10-10: tag at fa0701b about 12:20Z, CI run 38051611526 green, Gallery 12:30:57Z, GitHub 12:31:09Z. Test-PublishedRelease.ps1 (12:33Z): tag commit on master, Gallery SHA-512 matches the nupkg, 11 module files identical in nupkg and zip, manifest 5.0.0-rc7; hashes in the deployment notes, evidence in the session folder published-rc7.
• Gate 3 on the published rc7, 14:29 to 15:30 UTC (one detached driver; record Tests/Lab/Acceptance-2026-10-10-published-rc7.md, evidence gate3-rc7 with a manifest): the three matrix cells (OSFile19, 22, 25 with OSWin11E, both editions) 1,374 passed, 0 failed, 12 skipped, LIVE_RESULT_VERIFIED and CLEAN in each; the suite in 24 runs on six machine classes without a failure and with the host's skipped tests; the first lab with case 9 245 / 0 / 1 per edition, CLEAN in four domains and on both machines. Each controller run downloaded the package of the identity check (nupkg and DLL hashes equal). Same counts as the final local candidate; no checkpoint was taken.
• Handoff 1 (paths), measured at 5a5d58b (frozen Release, four configurations, CI wrappers, then AltCover): 1,310 cases per configuration, zero failures (baseline 3442194: 914 cases); coverage 3,192/3,634 sequence points (87.84%) and 1,273/1,978 branches (64.36%), against 74.21% and 50.39%. All 231 methods with 442 unvisited points are classified: 223 explained, 8 open for the maintainer. Skip eligibility was checked by row: all 578 skipped rows (137 distinct tests) are executed in two other configurations.
• Eleven defects were fixed, ten with a guard that is red before the fix and green after it (a red/green matrix over ten states of the branch: 76 rows red at the base f11ff41, none after the last fix; the leak of a native buffer has no guard). Mutation rounds at 5a5d58b: 25 of 26 detected, M25 (the check by type) an equivalent mutant. The matrix doesn't show that a test preceded its fix: each fix commit carries both. Report: Tests/Coverage/Quality-Gate-Paths-2026-10-09.md.
• Reviews: the custom security-reviewer can't start (its model is unavailable; no override). The built-in code-review agent made nine static passes of the paths work (no Blocker or Major) and four rounds on the matrix (one Major, record accuracy, resolved by the replay; Minors corrected); the built-in security-review agent found no exploitable vulnerability and two LOW items left for the maintainer (Next step 5).
• Live candidate of 2026-10-09 (09:20 to 09:51 UTC): 330 passed, 0 failed, 2 expected skips; published rc6: 326 passed, 4 expected failures, 2 skips; the 11 tested files match the ZIP. Independent probes verified the fixture removal on six machines (Tests/Lab/Acceptance-2026-10-09-quality-gate.md).
• Six checkpoints report Standard even after a successful ProductionOnly probe; policy restored, no restore performed: don't claim verified Production rollback evidence.
• Lab acceptance of the paths fixes, 2026-10-09 20:41 to 21:42 UTC: candidate 83149ee against its base f11ff41, the same 244 tests per edition (78 new): 486 passed, 0 failed, 2 expected skips against 338 passed, 148 failed (each green on the candidate); fixture removal verified. Record: Tests/Lab/Acceptance-2026-10-09-quality-gate-paths.md.
• Operating-system matrix, 2026-10-10 (record Tests/Lab/Acceptance-2026-10-10-os-matrix.md with CSV tables): the suite of the final candidate fdd7a8b passes on OSFile19/22/25, OSWin11E, OSWin11, and the host (24 runs, no failure; the baseline 83149ee fails 4 elevated and 20 basic-user tests on OSFile22 and OSFile25); the live controller passes in three cells (1,374 passed, 0 failed, 12 skipped) and in the first lab with case 9 (245 passed, 0 failed, 1 skipped per edition; fixture removed and verified). The Admin-role effective-access failures in earlier cells were stale account state, not the module: in a replay the baseline failed two of three cells and the candidate one, and one lifetime of about ten minutes fits 43 runs of 27 cells (the Windows mechanism is unknown). The controller names the case-3 account anew for each fixture (1dec389); four more cells with it passed. A dry run of Run-MatrixSequence.ps1 -Version 5.0.0-rc6 showed that the published-package path works. Labs at 07:50 UTC on 2026-10-10: no fixture or probe residue; OSWin11E shuts itself down an hour after its start.
• Handoff 5, the coverage unknowns, 2026-10-10 (report Tests/Coverage/Quality-Gate-Unknowns-2026-10-10.md; raw evidence in the session folder 816cf47d-2f80-4eba-8ac9-41702c49560b\files\qg-unknowns with a hash manifest). rc7 measured at fa0701b (four frozen configurations, AltCover): 3,198/3,649 sequence points (87.64%), 1,090/1,168 explicit branch points; 232 unvisited methods, all classified. Live suite on an instrumented copy (first lab and three cells, counts equal to the acceptance) and unit suite on OSFile25: together +9 sequence and +4 explicit branch points (the code of fdd7a8b); the cells add nothing to the first lab; no test or probe reaches the audit ownership retry or the audit read denial. The new tests add 45 points (getters of pipeline parameters; the paths report was wrong that no caller invokes a getter); 7 of 64 parameter sets closed, 51 partly, 1 open, 4 left to the maintainer. Cultures de-DE and tr-TR: two defects, fixed (419cfb3; 0028ccd, fbe0289, 8a625c8); the second was found by the one independent review (code-review: four Major findings, all resolved; the later delta had no second review). Final measurement 61e936e (build 8a625c8): 1,459 cases per configuration, 3,258/3,664 points, the same 187 unvisited methods; first lab 245/0/1 per edition on that build; the 22 files of the matrix suite 1,156/0 in 16 configurations on OSFile19/22/25 and OSWin11; both labs clean at 00:43Z. The tool's branch summary percentage is not read (it adds a point per method); the explicit branch points are 1,090/1,168. Not tested: Server Core (plan), ARM64, a localized system, non-Windows servers.

Next step

1. Gate 3 is done for the published rc7 (the record above). A changed binary (rc8, or the build of 5.0.0) needs the same cells again; the release procedure accepts the last prerelease for the stable build (his decision). Open: keep or replace the matrix VMs (about 60 GB) and the evaluation client (it shuts down every hour; OSWin11E is off), and a domain cell for Windows 11 26H1, whose client loses the secure channel to the Server 2025 domain controller. A kit script for the whole sequence would make the repetition one command (the driver is Run-Gate3.ps1 in the evidence; not in the kit).
2. The change that sets the next version (rc8 or 5.0.0) adds 5.0.0-rc7 to $publishedVersions; adding it earlier fails the reuse test (deployment notes). Every release step is the maintainer's.
3. He decides the open items of the paths report: FileSecurity conversions, RemoveAll account filters, lazy path overloads, abandoned PrivilegeEnabler, dot patterns of Get-ChildItem2 -Filter, the 17 owner-restore handlers without the later-command check, unused classes (Decisions 21/22). He also confirms or changes the proposed Decisions 22 and 24.
4. #34 stays open (Decision 23; no reply since 2026-10-06): the maintainer chooses between waiting for a test of the published candidate on the NetApp, EMC, and IBM ESS servers of the reporters (checklist: Tests/Lab/Non-Windows-File-Server-Test.md) and accepting the untested risk with a release-note caveat. No agent can accept it.
5. He decides the two LOW findings of the security review (record, Limits): the swallowed initialization errors of GetEffectiveAccess (a false "no access" instead of an error on an OS that refuses at initialization; fix: record the exceptions in authzException, with a regression test and a check of "the error stays" in the help and CHANGELOG), and the ACL of the stage folders under C:\ in the lab kit (they inherit Authenticated Users: Modify; protecting them is a design change of the controller and needs a new acceptance). The help could also say that a local standard user who asks about a domain account still gets "Access is denied".
6. Handoff 5 is done (Evidence). The maintainer decides whether the fixes 419cfb3, 0028ccd, fbe0289, 8a625c8 and the tests enter a new candidate (rc8), which needs the matrix cells and the first lab on its bytes, and he decides the open items of the report: hard-link names under another root (a defect with a reproduction), a piped AppliesTo property that a path drops, 12 getters of pipeline parameters, the 51 partly closed sets, the audit paths, Server Core (widens Decision 24), and ARM64.
7. Do not release stable 5.0.0 or equate a percentage with gate closure.
