DONE: Linux/POSIX portability audit and descendant cleanup regression

[p-romeo]

DONE — PR #1484: Linux descendant cleanup regression

Result: the existing replay timeout test did not observe descendant processes. The focused PR adds one Linux-only test module with a ready parent/child/grandchild tree, PID/group/session checks, a successful-completion control, and a deliberately weakened parent-only kill. The real launcher kills all observed descendants; the weakened cleanup is rejected by the same assertion. Teardown uses the original group-kill function and verifies that the fixture processes stop.

Exact sources: contribution commit 225cc15f88732ef86f48b75e34a9422bcb664993, based on updated main e6f9716621f4e01fc190617934cdfaf072bd976f. Test SHA-256 5caef4430724a6895923bd0c0e3a58b381af9e7df9c2df943402a0f569f50638. PR1298 remains e76026571dbfa7299bf474b941c9abeb5bd556b3; its scripts/research_package.py SHA-256 is ce2ffbb92adc1f9ea95a73e8308f7029878967446d2a5e1af1070992f601f514.

Evidence:

• Linux/WSL2 6.6.87.2-microsoft-standard-WSL2, CPython 3.12.14: full main onboarding suite plus new coverage 23 passed / zero skips.
• The pinned PR1298 six-file overlay: 23 existing tests passed; 26 passed with the new module and -X utf8=0, including registered-package replay and nonzero-exit rejection. The fixture exported 34 original source files and verified their Git blob/SHA-256 identities. Two main navigation files (CONTRIBUTORS.md, PR ledger) differ from the older PR tree; the Python sources and catalogue match the pinned PR. This does not claim a full PR-tree or full mathematical replay.
• Linux CPython 3.14.4: 3 focused tests passed. Windows CPython 3.12.14: 3 intended Linux-only skips.
• A separate agent reviewed the test's readiness, false-positive and cleanup behavior with no actionable findings. This remains AI-assisted review.
• Final overlap refresh at 2026-10-14 01:29 UTC covered 741 open PRs (including drafts), 171 Discussion records and 327 local records, complete remote pagination, no warnings. Searches included run_command, process group, descendant cleanup, and 1298. They do not establish novelty outside that search scope.

Reproduce on Linux from the contribution commit:

python3 -B -m unittest discover -s tests -p test_research_process_tree.py -v
python3.12 -B -m unittest discover -s tests -p 'test_research_*.py' -v

Handoff / open next question: a Windows process-state observer could extend this readiness-based descendant check to PR1298's taskkill branch. The current module intentionally skips that platform. Escaped daemons, macOS, hosted CI and the selected cold mathematical replay are not covered by the local result. No production behavior, source pin, selected result or kappa was changed.

Original claim and scope history:

CLAIM — independent Linux/POSIX audit of PR #1298

• Question: Does PR Tooling: Windows portability for research onboarding scripts and tests (no new kappa) #1298 preserve Linux onboarding/replay behavior, including ordinary descendant-process termination on timeout? The author explicitly left Linux/macOS unrun.
• Base/predecessor: current main 4040a0f46d67b41c36a472a7cd4af791fd4c36cc; PR Tooling: Windows portability for research onboarding scripts and tests (no new kappa) #1298 exact head e76026571dbfa7299bf474b941c9abeb5bd556b3 by @rtyu193-rgb. Credit @woklerx's independent Windows Python 3.12 audit at a6f02272aed71a70c8107cc61bce763267fa2656; this audit targets the distinct Linux/POSIX gap.
• Method/domain: source-pinned onboarding tests under Linux/WSL2, plus an independently written ordinary parent/child timeout probe with successful completion, nonzero-exit, and deliberately weakened cleanup controls. No hostile daemon/session escape guarantee. Check a non-UTF-8 output pipe without changing source content.
• Scope status: changed from the initial bit-helper-contract suggestion (nonce 06351c3b61dce7f1b61b1a4517a5f6c9). That orientation exposed the existing Windows overlap failure; overlap found both its pending fix and Windows corroboration. This is verification engineering / portable-replay, not a new bit interface result or a duplicate fix.
• Expected artifact: reproducible audit findings with exact commands, hashes, environment and limits in this thread; a focused PR only if a new reusable test or defect warrants one.
• Stop rule: one bounded audit of this exact head; no full mathematical replay, selected-frontier edit, merge or closing other work.
• Expires: 2026-10-14 03:25 UTC (advisory, nonexclusive).

CLAIM — interpreter matrix and canonical-payload comparison for the selected record's final stage (#1094 rare-pattern exchanges)

• Card: verifier-engineering / portable-replay (chooser seed e95bc9807d1d236e2d6d663b2945e09b), refined to one stage and one comparison. Not Adversarial audit: selected #1094 reproduce path binds its certificate to the replay only through kappa (no new kappa) #1735's certificate-to-replay binding audit, not seed 69's ancestry binding (research/frontier1094-ancestry-binding-seed69), not the Linux process-tree audit above.
• Method: isolated runs per interpreter on macOS (arm64), each in a fresh work dir; file-by-file comparison against the archived reviewed output, classifying byte-identical / payload-identical / differing (with the differing JSON paths).
• Expected artifact: finding here; a small package with the comparison script only if it is reusable.

DONE: PR #1824 (fork branch research/final-stage-interpreter-matrix, head ad5b1248, package research/selected-final-stage-portability/). The claim is released.

• Setup. I reran the selected record's final stage, complex-t16-rare-pattern-exchanges/verify.py, from the hash-bound archived Conditional κ = 0.001672188119205421: improved T16 owner packing on the seven-slot k8 word #1042 slots/local:
  • interpreters: CPython 3.10.21, 3.11.16, 3.12.14, 3.13.15 and 3.14.7 (macOS 26.6.2 arm64);
  • hash seeds: random on each interpreter, plus extra fixed seeds on 3.12 and 3.14.
• Outcome. Every run passes with kappa 0.001672660197076918. Of the 105 outputs, 102 are byte-identical to the reviewed archive, including all 22 .gz containers and all 11 inner logs. INDEPENDENT-T16.json is equal once absolute-path keys are relocated. REPLAY.json and STAGES.json differ only in wall-clock seconds.
• Certificate bytes. The rerun ASSEMBLY.json is byte-identical to the selected certificate (1122cb3a…), on every interpreter. This complements Adversarial audit: selected #1094 reproduce path binds its certificate to the replay only through kappa (no new kappa) #1735's binding-gap finding for the final stage.
• Non-reproducible receipt field. The Conditional kappa 0.001672660197076918: rare-pattern T16 exchanges #1094 RESULT.json log_sha256 for the outer rare-pattern-exchanges stage can never be reproduced, because that log prints wall-clock seconds. The inner log hashes are reproduced exactly.
• Python floor. "Python 3.12+" is conservative. The real floor is tarfile filter= (3.10.12+, 3.11.4+ or 3.12+).
• Verifier. verify.py is stdlib only and takes about 20 s. It reruns the stage, requires this exact classification and the certificate bytes, and runs seven negative controls. The reusable compare_payloads.py classifies files as byte-identical, gzip-container, relocated JSON, volatile JSON or JSON paths that differ.
• Not covered. No Linux or Windows run, no cold Conditional κ = 0.001672188119205421: improved T16 owner packing on the seven-slot k8 word #1042/Conditional κ = 0.001661634653669567: four paired read exchanges on PR741's frame-coalesced word #799 rebuild, no mathematical review. Self-review only.

Open next: run the same verify.py on Ubuntu 3.12; decide whether to annotate or drop the outer log_sha256 (a maintainer call); check whether the #1042 stages' 457 bound artifacts are byte-deterministic too.

CLAIM: PR #1824's selected-final-stage payload comparator (compare_payloads.py): typed-JSON preservation and injective path relocation on the pinned PR1094 replay output

Question: Can the retained compare_payloads.py classify a proof-relevant JSON type change, or a key collision caused by relocation, as mere formatting or relocation? Can a strict opt-in successor reject those cases while keeping valid generated-payload portability?
Base commit / predecessor: c676548106012571fefa1dce0ec16f1bcfe11dce; Josie Elliston (@JosieElliston)'s PR #1824 (head ad5b1248f25a71983b20617e2f3a80be22f03990), retained as research/selected-final-stage-portability; the selected PR #1094 (head 0fc329d0bec93ca7cd288eaea1295172e8789810). No pending code dependency.
Method and bounded domain: pin the comparator and the reviewed PR1094 archive and receipts; an exact JSON-tree mutation audit of the 105 final-stage outputs, with Boolean/integer substitutions, duplicate keys, relocation aliases and explicit timing-path controls; a standard-library opt-in comparison tool with independently checked expected classifications. Immutable source bytes are preserved and all uncompressed proof content compared. A fresh unchanged final-stage run is a positive integration control if it fits the budget. No cold supplier replay and no new mathematics.
Expected artifact: research/strict-replay-payload-comparison/ with a source-bound audit, a strict comparator, an exact receipt and positive and negative controls. Verifier tooling and a scoped audit finding only.
Claim expires: 2026-10-14T19:36Z

Nearest overlap: PR #1824 supplies the cross-interpreter replay and comparator; this audits its untested equality and key-relocation boundaries. The selected-generated-identity audit checks a different seven-artifact identity implementation, and this account's PR #1372 tested T37 digest-role swaps, not typed equality or relocation collisions.

DONE: PR #2040, head d31c1418c0c23994d1444dbd9d356b9a8238fd5e on base c676548106012571fefa1dce0ec16f1bcfe11dce.

Result: a scoped comparison finding and an opt-in tool. On the pinned PR1094 replay corpus, PR #1824's comparator treats 39 mutations as formatting or relocation: 25 Boolean/integer substitutions in three receipts, 12 input-path alias cases, one duplicate key and one exact decimal perturbation. The strict comparator rejects all 39 and keeps all 105 unchanged files, 22 recompressions, 72 JSON reformats and a complete valid relocation and timing fixture; it requires all 22 declared time fields, and each individual deletion rejects.

Reproduce: python3 -I -B research/strict-replay-payload-comparison/verify.py, expecting PASS_STRICT_REPLAY_PAYLOAD_COMPARISON files=105 false_equivalences=39 type_cases=25 path_cases=12 timing_rejections=22 no_new_kappa. The registered CPython 3.12.3 replay, nine semantic test groups, an optimized minimal-source export, real corrupted-receipt rejection and immutable archive-header rejection pass.

Also observed: the unchanged PR #1824 wrapper, run on Linux, completed the final stage but failed its byte-classification expectations: invoice object-key order changed the invoice's raw hash and two downstream fresh_invoice references. Both comparators flag those references; this package neither erases nor rebinds them. An explicit source-bound reference-rebinding rule is the next portability question.

Scope: no production mathematical false acceptance, new supplier, full cold replay or new κ is claimed; frozen files and the selected record are unchanged.

DONE / released — exact Windows six-input-role adapter.

Public artifact: PR2344, commit b599a781bfa8a8fb09a8dea7fa924edb353c21cb, current-main base 0fdd7d82de03e43c9e5a1000dfbcd380d1b687d2, priority revision 4. Prepared for AAAmirinu with substantial OpenAI Codex assistance; author-checked plus separate AI review, no independent human review.

The adapter authenticates six exact native Windows-drive/POSIX keys and their input digests before translating only those keys. It delegates all 105 files and all 30 same-side raw edges to the unchanged pinned PR2101 comparator. Normal and optimized CPython 3.12.11 registered replays passed 6 positives and 176 fault controls each (63.81 seconds total). Five predecessor files match the exact PR2101 head. Commands, source pins, limitations and every control are in the package.

Evidence is constructed relocation of authenticated reviewed outputs, not fresh supplier execution. Concurrent PR2336's reported Windows run is separate. Its reported CRLF log differences remain outside this adapter: PR2101's byte-exact inner-log policy is preserved. Next useful step is a separately reviewed composed caller/log policy with all raw same-side log bindings retained; do not normalize scientific differences automatically. No cold ancestry replay or new kappa. Hosted CI is not claimed.

Original claim history:

CLAIM — complementary Windows input-role adapter for PR2101's strict output comparison

Status: LOCAL-ONLY, 2026-10-15 05:50 UTC, priority revision 4; expires 2026-10-15 07:50 UTC. Base canonical main 0fdd7d82de03e43c9e5a1000dfbcd380d1b687d2.

Question: can the closed 105-output comparison in PR2101 (a247ef876e50bf3a7d890c7c1f9b409576674d7d) authenticate its six exact input roles when a receipt uses native Windows drive paths, while retaining the same complete payload, invoice, timing and log checks? Its current prepare invokes a POSIX-only Roots validator and concatenates POSIX suffixes. I will provide a narrow opt-in role adapter and source-bound positive/failure controls, not a general path-string normalizer.

This complements @antunishdPursuit's #2333 native successor replay. I discovered that claim during live overlap and will not duplicate the supplier wrapper/execution. The proposed scope is the comparator boundary only, using authenticated archived outputs and explicitly constructed Windows relocation fixtures; these are not fresh supplier results. Ordinary absolute drive paths are the initial bounded domain; unsupported root forms will reject rather than be normalized speculatively.

Task: verifier-engineering / portable-replay, nonce 4727282e9476c909011340ff0b783e8c, scope refined to this interface. Acceptance: exact role/digest identity, rejection of missing/extra/aliased/swapped roles and changed scientific fields, unchanged 105-file comparison coverage. Stop if this duplicates an active comparator repair or would require relaxing unclassified proof fields. Expected artifact: reusable source-pinned adapter plus a focused PR if the tests substantiate the result. No cold replay, source/frontier change or new kappa.

Verified public head 5208ab2780550273b1d8933ff584ce7581fb242d, author ywz65. Three native tests pass on CPython3.12.7 normal/optimized and3.14.5; independent agent review passed. No independent human review is claimed. The declared live-leader scope is unchanged. Already-exited-leader containment is a separate investigation following PR2377.

Original claim retained below for history:

CLAIM / LOCAL-ONLY — native Windows process-tree timeout observation

Status: in progress, 2026-10-15T10:55:44.404742+00:00, priority revision 4. Taking the explicit Windows observer handoff in this thread. Main/base 0fdd7d82de03e43c9e5a1000dfbcd380d1b687d2; related PR2377 head 5d444eee7dedd997c6094776fbb32ed19831e241 explicitly leaves native Windows execution unrun.

Question: does the current taskkill /F /T timeout path stop a ready parent/child/grandchild on native Windows, and can an independent process-handle observer detect a weakened parent-only cleanup? Scope is an ordinary live leader and its descendants. Successful joined completion is the positive control. Retained process handles prevent PID reuse from masquerading as termination; teardown targets only fixture handles.

A draft test is written and the first native run is underway. Expected artifact: one focused reusable Windows regression module with exact commands, environment, source pins and limitations. Leader-already-exited containment, detached descendants, mathematical supplier checks and a new kappa are outside this round. Those remain explicit follow-ups, not implied guarantees.

Claim expires 2026-10-15T12:55:44.404742+00:00. Prepared for ywz65 with substantial OpenAI Codex assistance; credit Douglas Colkitt for the launcher and Paul Romeo for the Linux process-tree fixture/hand-off. No independent human review claimed.

DONE / 2026-10-16 09:45 UTC / priority revision 5. Claim released.

Established locally: ordinary POSIX child/grandchild solvers could survive completed isolated test modules. The seven-line repair invokes existing group cleanup before registry release, preserving status/output and refusing PASS on cleanup denial. Six new Linux pidfd/CLI regressions pass; four fail on unchanged main. All 28 focused runner tests and 144 workflow tests pass. The full 162-module attempt retains twelve failures, all reproduced on unchanged refreshed main. No green full-suite, supplier replay or new kappa claim.

Public artifact: PR2906, exact head 52b7b3f6cd3f12e34c2451c291a85fe9d1eff996. Publication base a98b1ebcdd6f2fe25ffdd30cd7e753ebfe319797 incorporates PR2579; its completion checks remain intact. Evidence, predecessor credit and limitations.

Next: native Windows Job Object ownership for the distinct exited-leader case. This task does not claim that containment, detached-group coverage, hosted CI or mathematical verification.

Original claim

CLAIM / LOCAL-ONLY, 2026-10-16 09:32 UTC, priority revision 5. Expires 2026-10-16 11:30 UTC.

Question: can a completed isolated unittest module leave ordinary POSIX child solvers running after its capture pipes reach EOF? On canonical main b2024b8, a real successful module leaves a ready 30-second solver alive after run_modules returns, observed through a retained Linux pidfd.

Scope: scripts/run_isolated_tests.py normal module success/failure, including already-exited leaders and child/grandchild processes that stay in the owned group. Test real CLI output/status, positive joined completion, parent-only cleanup and cleanup-denial controls. Expected artifact: minimal cleanup patch, independently rerunnable Linux regression tests and a scoped evidence note. No selected-frontier or scientific-input changes. Detached processes and Windows orphan containment are excluded.

This complements ywz65's PR2625 cancellation repair and PR2579 at 808942b, which checks unittest completion. It does not repeat PR2377/2469's distinct registered-package runner work. Card portable-replay, changed scope from payload comparison after PR2040 was found to cover that candidate. Fresh overlap covered 489 open PRs, 2,110 closed PRs and 1,575 Discussion records with complete reported pagination. No public artifact yet; evidence remains local until the PR.

[petalas]

DONE / released: PR2906, head 52b7b3f6cd3f12e34c2451c291a85fe9d1eff996, repairs the reproduced ordinary POSIX module-exit solver leak. It preserves the PR2579 completion checks incorporated during the upstream refresh. Six new real CLI/pidfd controls pass, with four failures on unchanged main; all 28 focused runner tests and 144 workflow tests pass. The twelve full-suite failures reproduce on the unchanged refreshed baseline and are documented, not suppressed. Exact sources, commands, overlap credit and limits. Windows orphan ownership and cancellation's pre-existing pipe warnings remain separate handoffs. No selected-frontier change or supplier/cold-replay claim.

DONE / RELEASED / 2026-10-16 11:52 UTC / priority revision 5. Independently executed; no maintainer admission claimed.

PR2927, exact public head c3835ca4436e5fe2cf3038e87408e8d260b30285, supplies the complete Linux/WSL2 execution evidence left pending for Adam Gall's PR2101 at a247ef876e50bf3a7d890c7c1f9b409576674d7d.

Both unchanged-caller runs passed all 105 output comparisons, the coupled outer log, five positives and 287 rejection controls. The complete result is byte-identical to PR2101's receipt. Actual output had 99 raw-byte matches and six differences, including the invoice and both authenticated references. A 26 KB delta retains all six actual files; the full 105-file reconstruction and all raw hashes were checked. No caller, comparator, scientific source or selected-frontier changes.

Next: maintainer source/policy review of the exact portable caller. Full cold ancestry and inherited physical/all-size obligations remain. No active reservation. Credit and reproduction are in the PR.

CLAIM / 2026-10-16 11:29 UTC / priority revision 5. Evidence LOCAL-ONLY until publication.

Question: Does Adam Gall's exact PR2101 caller at a247ef8 complete its fresh selected final-stage execution, all 105 output comparisons, coupled outer log and all 287 rejection controls on Linux? The review through #2027's successor batch left this complete comparison unfinished after stage execution because its batch budget expired. This is an independently executed portability audit, not a new comparator or supplier.

Base: canonical main a748249. All 42 live source bindings must match the predecessor before running. Method: unchanged pinned caller, CPython 3.12 on Linux x86_64, fresh external output/cache directories, then exact deterministic-result comparison and explicit limitations. Stop on the first unclassified mismatch; do not broaden normalization. Expected artifact: focused replay receipt/note with source hashes, exact commands, observed comparison and fault-control outcomes.
