Active context

Current focus

Handoff 1 of the quality gate is finished on ai/quality-gate-paths, from the reviewed head f11ff41 of #117: 28 commits, which the maintainer pushed as draft #118 (CI green on 83149ee). Both stacked PRs stay open and green; rc6 remains the latest published candidate and 4.2.6 the stable Gallery version. Every C# method that no test visits is classified (223 explained, 8 open for the maintainer), and the other paths have behavior tests. Eleven defects were fixed, ten of them with a regression guard that is red before the fix and green after it (owner restore, InheritedFrom, a later command that ends the pipeline or throws, also at the error, verbose, and debug streams, -Filter brackets, null, and *.*, public object APIs, a privilege left enabled); the leak of a native buffer has no observable guard. The lab acceptance of those fixes was repeated on 2026-10-09 (below); the published package still needs its own acceptance in gate 3. Decisions 21/22 and stable 5.0.0 remain gated; Decision 22 is proposed: the agent confirmed all ten choices on 2026-10-09 under the maintainer's delegation, and his own confirmation is open.

Evidence

• rc6 Release run 37839669028, attempt 2, succeeded; GitHub prerelease with zip appeared 2026-10-09 07:01:34 UTC. First attempt proves HTTP 409 after Gallery publication, not the previously assumed retry chronology.
• #116 is open, base master, head d25647d, CI build/wiki passed. rc7 publication is pending. The follow-up does not change that PR's head.
• Local changes: deletion/ownership guards (a97e46f); all scopes and inheritance (e7ee203); absolute basic-user results (51dec86); exact-package publication recovery (95b827e); first-hidden-item fix (d610372); Force/descriptor guards (3442194); SMB regression above.
• Hidden omission was reproduced in all four configurations before the fix. No parameter/design change. Publication tests are wholly mocked; exact ordinal SHA-512 identity is required, no real upload occurred.
• At 3442194 (start of Handoff 1): 914 cases per configuration, 2,641/3,559 sequence points (74.21%), 974/1,933 branches (50.39%), 918 unvisited points. All skipped templates had executed counterparts.
• Handoff 1 result at 5a5d58b (frozen Release, four configurations, CI wrappers, then AltCover): 1,310 cases per configuration, zero failures; passed/skipped: elevated Desktop 1,286/24, Core 1,255/55; basic Desktop 1,076/234, Core 1,045/265. Coverage 3,192/3,634 sequence points (87.84%), 1,273/1,978 branches (64.36%); 231 methods with 442 points stay unvisited, all classified: 223 explained, 8 open. Skip eligibility was checked by row from a second full run per configuration: all 578 skipped rows (137 distinct tests) are executed in two other configurations.
• Mutation rounds on the frozen tree at 5a5d58b: 26 mutations in four rounds; 25 are detected by their guard in every configuration where it runs, and M25 (the check by type, an equivalent mutant) survives as expected. At d61dffa three had escaped (the verbose and debug rows ran under the CI runner's Stop, and an Init test could not fail for its branch), which led to f4a16e1. A first round at 630926f had let one mutation escape, which led to the -Filter bracket defect.
• Red/green matrix (measured after the last measurement, because the first red runs were not kept): the final tests of the eight files that guard the fixes (650 cases per configuration) over the production code of ten states of the branch, built in Release and run with the focused runner (it sets Stop like the CI wrappers) in the four configurations. 76 rows (73 in the basic configurations) fail at the base f11ff41, each is green at the step of its fix, none breaks later, and d44a200 has none (the control). Defect 9 (the native buffer) has no guard. The matrix does not show that a test was written before its fix: each fix commit carries both, and the red runs of that time were not kept.
• Review: custom security-reviewer could not start (model unavailable); the built-in read-only code-review agent made nine static passes: no Blocker or Major; its Minor findings led to the *.*, help, test, later-command, error-stream, and privilege fixes. Report: Tests/Coverage/Quality-Gate-Paths-2026-10-09.md with an appendix of explanations and CSV rows; raw evidence is in the session folder 4b12e2f4-d4c7-4a5d-883a-ddb7421c4848\files\qg-paths.
• Live packaged candidate, 09:20 to 09:51 UTC: 330 passed, zero failed, two expected Server-module skips. Published rc6: 326 passed, four expected failures (Hidden and rc7 warning text in each edition), two skips. Tested folder and all 11 ZIP files are byte-identical.
• Temporary host result verifier failed on Desktop JSON wrapping/full test names; corrected verification passed on unchanged raw results in both editions. Cleanup wrapper's broad Error.Count was not acceptance proof. Independent probes verified all fixture objects/members/profiles gone from six machines. Raw failing markers and corrected evidence kept.
• Review of the lab candidate: one read-only independent code review approved, high confidence, no significant findings or confirmed exploit.
• Six checkpoints exist but report Standard, even after a successful temporary ProductionOnly probe; policy restored, no restore performed. Do not claim verified Production rollback evidence.
• Lab acceptance of the paths fixes, 20:41 to 21:42 UTC on 2026-10-09: the candidate 83149ee and its base f11ff41 ran the same 244 tests per edition (78 new, case 10) from their extracted packages. Candidate 486 passed, 0 failed, 2 expected skips; baseline 338 passed, 148 failed, each green on the candidate; both editions gave the same counts. Fixture removal verified by a separate read-only check in four domains and on both file machines; six checkpoints (Standard type, no restore). Record, results CSV, and limits: Tests/Lab/Acceptance-2026-10-09-quality-gate-paths.md. This covers the gate-3 handoff table of the path report, except the published package and the other operating systems.
• Wider matrix not deployed: 13 Server 2025 VMs; Windows 11/2019/2022 media present, OS detection cache empty. #34 has no reply since Oct 6.
• Full evidence: session artifact quality-gate-3442194-20261009; repository report Tests/Lab/Acceptance-2026-10-09-quality-gate.md.

Next step

1. The maintainer reviews and integrates ai/quality-gate-paths (stacked on #117; no remote change was made here) and decides the open items listed in the 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).
2. Gate 3: the affected live acceptance of the paths fixes is repeated (record above). Accept the published package again before the next candidate counts as accepted; no local upload.
3. Retain stacked-PR order (15), obtain Decision 22 review, finish the OS matrix and obtain or explicitly accept #34 feedback through other gates.
4. Do not release stable 5.0.0 or equate a percentage with gate closure.
