From d34eee989c247d0145e63e33e20d31dbbd373203 Mon Sep 17 00:00:00 2001 From: James Sesler Date: Sun, 23 Aug 2026 04:53:40 -0400 Subject: [PATCH 1/2] fix: five verified defects from the Broad-Side self-scan (#128-#132) - #128 writeLibraryConfig now derives its parent directory with dirname(), fixing ENOENT on Windows where the hand-rolled forward-slash match treated every path as a bare filename. - #130 isWithinPath respects roots that already end in a separator (/, C:\), which previously produced a double-separator prefix that rejected every legitimate subpath. - #131 acquireLock closes the lock descriptor on a write failure instead of leaking it until GC. - #129 the phase runner settles the compaction promise with false when no compaction occurred, so continuation stops paying the full COMPACTION_SETTLE_TIMEOUT_MS on every non-compacted continue. - #132 completeValidatedPhase re-validates the output inside the status lock: a stale PASS whose output changed since the caller's validation refuses with a clear error and leaves status untouched. 6 regression tests in tests/broadside-scan-fixes.test.mjs; 348 total. --- CHANGELOG.md | 8 ++ core/completion.ts | 27 ++++- core/orchestrator-config.ts | 7 +- core/status.ts | 9 +- core/utils.ts | 8 +- extensions/codecarto/agent-runner.ts | 6 ++ tests/broadside-scan-fixes.test.mjs | 143 +++++++++++++++++++++++++++ 7 files changed, 200 insertions(+), 8 deletions(-) create mode 100644 tests/broadside-scan-fixes.test.mjs diff --git a/CHANGELOG.md b/CHANGELOG.md index 4979ac1..de4fc78 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -4,6 +4,14 @@ All notable changes to this project are documented here. The format is based on ## [Unreleased] +### Fixed + +- **Windows: `writeLibraryConfig` no longer ENOENTs on parentless paths** (#128). The hand-rolled `includes("/")` separator check treated every Windows path as a bare filename, leaving `mkdir` a no-op before the write failed. Now derives the parent directory with `dirname()`. +- **`isWithinPath` accepts subpaths of filesystem roots** (#130). Appending a separator to an already-terminated root (`/` → `//`, `C:\` → `C:\\`) produced a prefix no real path starts with, rejecting every legitimate subpath. Trailing separators are now respected before prefixing. +- **`acquireLock` closes the lock descriptor when `writeFile` throws** (#131). A non-EEXIST write failure previously leaked the file handle until GC. +- **Phase continuation no longer burns the full compaction settle timeout** (#129). When a phase run ends without a compaction event, the pending compaction promise is now settled with `false`, so `waitForCompaction` returns immediately instead of waiting out `COMPACTION_SETTLE_TIMEOUT_MS` on every continuation. +- **Completion re-validates under the status lock** (#132). `completeValidatedPhase` now re-runs `validatePhaseOutput` inside the atomic status update; a stale PASS whose output changed since the caller's validation refuses to complete (and leaves status untouched) instead of completing a phase on evidence that no longer holds. Validations that never touched a file on disk (no `outputPath`) keep the legacy path, matching the synthetic-validation contract in unit tests. + ## [0.16.0] — 2026-08-17 The field-test round.

Two do: #130 and the #132 stale-PASS refusal. The other three pass against unfixed code — #128 is a Windows-only path bug that POSIX cannot reproduce, #131 covers acquire/release rather than the writeFile-throws path the fix guards, and #129 exercises waitForCompaction rather than runPhase where the fix lives. The fixes are still right; the claim about them was not. Saying so keeps the next reader from assuming those three are protected against a refactor that reverts them.
