M15 Increment 47 — Signature B Root Cause / Resolution (Diagnostic Hardening)

Status: Root Cause UNPROVEN / UNRESOLVED

Under 26 bounded reproduction runs (1 baseline full suite pass, 20 sequential diagnostic pass runs under run-signature-b-pass.mjs, and 5 runs under concurrent monorepo lint/typecheck load), Signature B did not reproduce (0 genuine captures). In strict accordance with engineering guardrails, no speculative production changes have been introduced, and Signature B remains explicitly UNRESOLVED. This PR hardens diagnostics and correlator telemetry only; it is NOT a production root-cause fix.

Justified Diagnostic Hardening

Investigation, adversarial review, and automated bot feedback (Qodo and CodeRabbit) identified 4 concrete failure modes and blind spots in the diagnostic harness (packages/api/test/diagnostics/):

Cross-Directory Single-Candidate False Attribution:
The single-candidate basename fallback in matchChild previously matched across directory boundaries if only one child log shared the same basename. If src/auth/login.test.js terminated before emitting a child log while src/ui/login.test.js ran and produced a child log, the correlator erroneously assigned src/ui/login.test.js's child log to src/auth/login.test.js.
Fix: Gated the fallback on !parentNorm.includes('/'), ensuring basename fallback is only applied when the parent failure path itself lacks directory structure.
Host-Independent Path Casing, Casing Aggregation, POSIX Backslash Preservation, & Platform Context:
isWindowsPath previously used process.platform === 'win32', causing Windows captures analyzed on POSIX to compare paths case-sensitively, while POSIX captures analyzed on Windows were erroneously treated as case-insensitive (risking false attribution between case-distinct Linux paths). Furthermore, detecting Windows purely via str.includes('\\') misclassified valid POSIX filenames containing backslashes as Windows, splitting single filenames into multiple segments and forcing case-insensitive matching. In addition, casing variants of the same child process on Windows could produce separate map entries, causing matchChild to report false ambiguity and drop lifecycle evidence. Finally, inferring parent Windows separator normalization from candidate children could convert POSIX parent backslash filenames into directories.
Fix: Decoupled Windows path detection from analyzer host OS and refined isWindowsPath(filePath) to detect Windows paths strictly from unambiguous syntax (Windows drive prefixes or backslash UNC prefixes ^\\\\{2}[^/\\], rejecting forward-slash UNC // per POSIX syntax) and explicit capture metadata (record.isWindows). In matchChild, parent separator normalization depends strictly on parent platform context (parentIsWindows or isWindowsPath(parentFile)), while child Windows context is used solely for case-folding. parseTapFailures, correlate, and the CLI accept explicit platform options (isWindows: boolean), run-signature-b-pass.mjs explicitly propagates platform context { isWindows: process.platform === 'win32' } during live test runner passes, the CLI derives capture platform only when child logs are uniformly Windows (allWindows) or uniformly POSIX (allPosix) — preventing mixed or stale logs from forcing Windows semantics onto POSIX paths — and in readChildLogs, casing variants for the same Windows child file aggregate into a single entry, avoiding false ambiguity in matchChild.
Signed NTSTATUS Crash Misclassification:
Windows/libuv crash exit codes are 32-bit unsigned NTSTATUS values (e.g. 0xC0000005 Access Violation), but Node/libuv often exposes them as signed 32-bit integers (-1073741819). Direct comparison against 0xC0000005 evaluated to false for negative numbers.
Fix: Converted exit codes to unsigned 32-bit integers via (exitCode >>> 0) in classifyTermination, correctly recovering the standard 0xC0000005 representation.
TAP YAML Scalar Parsing, Quote Stripping, Non-Finite Numbers, & Bare String Failures:
parseTapFailures previously expected strictly unquoted values for error: and failureType:. Furthermore, when TAP reporters wrap scalar numbers in quotes (e.g. exitCode: '1' or duration_ms: '234.5'), standard Number("'1'") returned NaN, silently dropping exit-code classification. Additionally, non-finite numeric strings (Infinity, -Infinity) leaked through Number.isNaN checks without being converted to null. Finally, correlate accepting bare string file inputs did not initialize null-valued parent properties.
Fix: Added an unquote utility in parseTapFailures stripping single and double quotes from string and numeric scalars prior to Number(...) coercion, applied Number.isFinite(...) to convert NaN, Infinity, and -Infinity to null, and normalized bare string inputs in correlate into complete records with null-valued parent fields.

Scope of Changes

The diff is strictly confined to 5 files relative to origin/main:

packages/api/test/diagnostics/run-signature-b-pass.mjs (propagated platform context from runner pass to correlator)
packages/api/test/diagnostics/signature-b-correlate.cjs (correlator implementation hardening, uniform CLI platform derivation)
packages/api/test/diagnostics/signature-b-correlate.test.ts (targeted regression tests)
docs/PROJECT_STATE.md (recorded Increment 47 facts and updated header)
docs/ROADMAP.md (extended tracked Signature B entry with Increment 46 & 47 facts)

No production runtime code, persistence packages, or shared configs were touched.

Main Synchronization & Documentation Sync

Synchronized with origin/main: Incorporated PR fix(persistence-test): give each suite ownership of the rows it creates #38 (90211916fbdaca290e994fc7d556e7f320e4ddd4, closing M15 Increment 46) via a clean git merge (c49b57d).
Milestone Documentation: With Increment 46 merged to main, the prior documentation deferral is resolved. Increment 47 is recorded in docs/PROJECT_STATE.md (append-only entry + bumped header) and docs/ROADMAP.md (chronologically extending the tracked Signature B follow-up entry with Increment 46 observations across packages/persistence and Increment 47 correlator hardening facts).

…rectory false attribution and signed NTSTATUS codes Harden signature-b-correlate against three proven concrete blind spots: - Require parent failure path to be a bare filename without directory segments before allowing single-candidate basename fallback, eliminating false cross-directory child log attribution when a file terminates before logging. - Perform case-insensitive path comparison on Windows in matchChild so casing differences between argv[1] and runner paths do not cause false misses. - Convert 32-bit exit codes to unsigned in classifyTermination so signed negative NTSTATUS values (e.g. 0xC0000005 as -1073741819) are correctly mapped to table candidates and the 0xC0000000 range. - Relax parseTapFailures regex to accept single-quoted, double-quoted, or unquoted YAML values for error and failureType. - Add 4 regression tests pinning each guarantee. - Signature B remains UNRESOLVED.

Harden Signature B diagnostic correlation for Windows failures

🐞 Bug fix 🧪 Tests 🕐 10-20 Minutes

AI Description

• Prevents child logs from being attributed across directories while preserving safe filename
 fallbacks.
• Normalizes Windows path casing and signed NTSTATUS values for accurate crash classification.
• Expands TAP scalar support and regression coverage without claiming Signature B resolution.

High-Level Assessment

The targeted hardening is appropriate because it fixes proven diagnostic blind spots without introducing speculative production changes. A general YAML parser or broader path-resolution abstraction would add dependency and integration complexity disproportionate to the correlator’s bounded TAP format; Signature B should remain unresolved until reproducible evidence identifies a production cause.

Description

The CLI marks every parent failure using the analyzer's process.platform, so captures analyzed on

lifecycle evidence.

The CLI passes process.platform into parseTapFailures, which stores it on each failure;
correlate then gives that failure flag precedence and passes it to matchChild. normalizePath

case folding, despite isWindowsPath explicitly documenting that analyzer-host platform must not
determine capture semantics. Child-log parsing already preserves capture-side isWindows or

## Issue description
The CLI passes the analyzer host's platform as the origin of every captured TAP path. Cross-host analysis therefore overrides capture-side path semantics and can miss or falsely attribute child logs.

## Issue Context
Child logs already retain capture-side Windows metadata. Do not infer capture origin from `process.platform`; derive it from capture metadata or normalize each candidate using authoritative capture-side provenance. Add CLI-level cross-host tests for both Windows captures analyzed on POSIX and POSIX captures analyzed on Windows.

The CLI sets Windows semantics for every TAP failure when any child-log record is marked Windows. If
the directory contains a Windows record alongside POSIX or stale records, POSIX parent paths can be
normalized with Windows separators and case folding, causing valid evidence to be missed or

Evidence
The CLI computes hasWindowsChild across all child entries and passes the resulting single value to
both parseTapFailures and correlate. However, child-log records are classified individually from
metadata or path syntax, and matchChild uses the one parent platform value for all entries;
consequently, a single Windows record can force unrelated POSIX failures through Windows
normalization and case folding. The added test creates only Windows child records, so it does not
exercise mixed or stale artifacts.

3. ~~Relative Windows parents unmatched~~ ✓ Resolved 🐞 Bug ≡ Correctness

Description

When parentFile is a relative Windows path such as dist-test\test\foo.test.js, isWindowsPath

Both suffix and basename matching then fail, incorrectly reporting that no child log exists and

deliberately not recognized by isWindowsPath, line 370 preserves their separators and the fallback
treats the entire path as a basename.

instead used by matchChild to lowercase paths and perform case-insensitive suffix and basename
comparisons when either path is Windows-origin, demonstrating that casing—not separator
conversion—was the host-dependent behavior.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The module documents that path normalization supports captures read on a different platform, and an
existing test explicitly treats Windows captures analyzed by CI as supported. However, the new
casing behavior checks the reader's process.platform, while readChildLogs preserves the captured
path's casing; the new regression test is skipped on every non-Windows reader and therefore does not
cover the documented workflow.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
Windows path case normalization currently depends on the host analyzing the capture. Detect Windows-origin paths from the captured path itself and compare those paths case-insensitively even when analysis runs on another platform.

## Issue Context
The correlator explicitly supports captures produced on one platform and read on another. A Windows absolute child path can retain mixed casing when read on Linux, causing suffix matching against a differently-cased TAP path to fail.

📝 Walkthrough

Walkthrough

The diagnostic correlator now normalizes failures and signed termination codes, parses flexible TAP scalar formats, and applies platform-aware Windows and POSIX path matching. The CLI passes platform context through parsing and correlation. Tests and project records cover the updated behavior.

Changes

Diagnostics correlation

Layer / File(s)	Summary
Failure and termination normalization `packages/api/test/diagnostics/signature-b-correlate.cjs`, `packages/api/test/diagnostics/signature-b-correlate.test.ts`	TAP parsing accepts flexible quoting and spacing. Non-finite numeric fields become `null`. String failures receive normalized fields. Signed and unsigned termination values classify consistently.
Platform-aware path matching `packages/api/test/diagnostics/signature-b-correlate.cjs`, `packages/api/test/diagnostics/signature-b-correlate.test.ts`	Path handling distinguishes Windows and POSIX semantics. Windows matching is case-insensitive and merges casing variants. POSIX matching preserves separators and case sensitivity. Child matching isolates directories and supports explicit Windows context.
CLI platform wiring `packages/api/test/diagnostics/signature-b-correlate.cjs`, `packages/api/test/diagnostics/run-signature-b-pass.mjs`, `packages/api/test/diagnostics/signature-b-correlate.test.ts`	The CLI and diagnostic runner derive platform context from flags, child metadata, or path data and pass it to TAP parsing and correlation.
Correlator contract and validation records `packages/api/test/diagnostics/signature-b-correlate.test.ts`, `docs/PROJECT_STATE.md`, `docs/ROADMAP.md`	The declared APIs include platform options and `isWindowsPath`. Documentation records the expanded test totals and correlator fixes.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 02bc1

The diagnostic correlator changes Windows path handling and platform propagation. Remaining uncertainty around case-variant aggregation and relative Windows-path context could still misattribute or miss diagnostic lifecycle records, so these concerns should be resolved before merge.

Deferred while PR #35 held the milestone docs; that is merged, so the Increment 48 payload lands here rather than only in the PR body. PROJECT_STATE gains the increment ahead of 47: the pre-fix residue as measured (11/11 passing while leaking 25 rows a run, twice over), the single root cause, the ownership boundary and what was rejected, the `./test-support/fixtures` export, the leased-client release fix, the regression proven red then green, A/B/C on one database, and 8 of 9 mutations killed with the survivor named rather than rounded up. Two findings are recorded as OPEN rather than quietly carried: analysis-cache-durable never migrates and so depends on state another suite establishes (6 of 10 fail on a fresh database), and test:counts exits 1 because services/gateway sits outside the workspaces. Both are bounded follow-ups for their own PRs; neither is fixed here, and the gateway remedy is left to be established rather than assumed. Counts are labelled as readings, not invariants, and are given for both the implementation HEAD and after this branch was synchronized with main, since Increment 47's expanded correlator suite moved them. Increment 47 is left exactly as it was written, Signature B included: it remains UNRESOLVED, now with 0 occurrences observed during Increment 48, which bounds nothing more than the rate.

…ration tests (#41) * fix(api-test): clean pg-security shared database fixtures The suite created users, credentials, roles, sessions and rate-limit buckets in the shared database and closed its pools without deleting any of them. Every identifier it mints is a fresh uuidv7, so a second run never collided and all 11 tests passed on a database they had already polluted -- while each run added 25 rows: 4 users, 4 credentials, 4 roles, 4 sessions and 9 buckets. Measured, not inferred: two runs against one PostgreSQL 16 database went 11/11 then 11/11, with the row counts doubling in between. Each test now runs inside withSharedDatabase from Increment 46 and names what it owns. Users are removed by id, which cascades to credentials, roles and sessions -- the only foreign keys to users without ON DELETE CASCADE are games.white_id and games.black_id, and this file creates no games. Buckets are removed by exact key, never by the shared "integration:" prefix, which is a naming convention other suites use rather than an ownership claim. Identifiers are recorded before the statement that creates the row. The reverse order loses exactly the rows worth cleaning: a create that commits and is then contradicted by a failing assertion never reaches the line that would have registered it. Reaching the helper needed a ./test-support/fixtures subpath export; withSharedDatabase was otherwise unreachable outside the persistence package. The API package already consumes ./test-support for withTestDatabase. Also fixes a hang the audit turned up: the bucket-creation race test read two backend pids between admin.connect() and the try that releases the client, so a failure there leaked the lease, and a pool with a client still checked out never finishes end(). Verified directly -- pool.end() does not settle while a client is outstanding. The new regression runs the real suite as a child process against a disposable database and compares row identity before and after, because the defect is invisible from inside: the suite's own assertions pass just as well on the hundredth run as on the first.
