|---|---|
Bounded catalog path identity src/codex/catalog/heal-observation.ts, tests/codex-integration/codex-catalog-self-heal.test.ts, structure/codex-home.md |
compareCatalogHealPaths performs bounded path inspection and returns same, different, or unknown. Tests cover filesystem aliases, hardlink identity, unavailable paths, and bounded lookups. The documentation describes path identity behavior. |
Healing and publication gates src/codex/catalog-self-heal.ts, src/codex/convergence.ts, tests/codex-integration/codex-catalog-self-heal.test.ts, tests/codex-integration/codex-catalog-heal-integration.test.ts, structure/codex-home.md |
Healing and candidate commits require a proven path match. Unknown relationships stop observation reuse or commit processing. Publication and release handling use path comparison results to update tracking and lifecycle state. Integration tests cover suspended heals and a symlink chain that exceeds the comparison bound. |

The test-runner pin changes from Bun 1.4.3 to 1.4.4. Tests cover matching and differing caller versions and an incorrect override. CI comments and documentation describe independent runtime-role validation and candidate promotion checks. |
Buffered upload early-response test

Early TLS response fixture tests/claude-integration/claude-picker-upload.test.ts |
The fixture adds a half-open TLS mode that records request completion and response flushing. The buffered early-response test asserts that the response flushes before the request completes. |

- Around line 34-50: When the loop bounded by CATALOG_HEAL_MAX_LINKS completes
normally, return an unavailable observation that marks identity as uncertain, so
compareCatalogHealPaths returns "unknown" rather than relying on lexical path
comparison. Add a test that reaches the hop limit without exhausting the read
budget and verifies the result is "unknown".

Independent source review (gpt-6.1-sol, dispatched by the triage manager, 2026-10-24) at head VERDICT: MUST-FIX Reviewed current head
All six changed files reviewed. Existing tests remain registered; NOT RUN: tests, typecheck, builds, validation scripts, native reproduction. No edits or GitHub mutations. This is a read-only source review; merging still requires the gates named above (exact-head CI, |
…tics A relative symlink target containing .. was normalized lexically, so a symlinked intermediate directory made the comparator follow the wrong parent. Walk each intermediate component within the existing read budget: resolve symlinked or missing directories with realpath, treat non-directories and failures as unknown, and keep the leaf for the next lstat hop.
Measured OS behavior splits by platform: Windows normalizes .. lexically across junctions/reparse points and even past missing components, while POSIX resolves each directory and refuses a missing crossing. Keep lexical resolve on Windows; on POSIX walk each intermediate component inside the read budget, record intermediate symlinks in the revalidation snapshot, and treat missing or non-directory crossings as unknown. Regressions assert the independent readFileSync/realpathSync result before the comparator verdict, and the POSIX-only literal-backslash case is an explicit platform skip.
A symlinked intermediate that resolves to a regular file must fail the traversal with ENOTDIR on POSIX; dirname() after realpath would have accepted the wrong catalog. Stat the resolved intermediate inside the read budget, require a directory, and record the resolved identity in the link snapshot so revalidation also catches a target swap.
|
Addressed the path-resolution finding in POSIX link targets now resolve intermediate directories before applying Official Bun 1.4.4 Windows verification passed 115 related tests before the final POSIX-only guard; unchanged Windows behavior was not rerun. Type, structure, privacy and diff checks passed on the final candidate. Independent source review cleared the delta. Native POSIX execution and exact-head lane=all remain pending, so the PR stays Draft and the platform-validation requirement is not marked complete. |

Maintainer integration decision (L-B lane, v2.93.0 release prep, release-blocking): MERGED into Review history. Each round was a fresh independent gpt-6.1-sol review at high reasoning. Fixes were pushed as normal commits; nothing was rebased or force-pushed.

Retargeted to dev. The four conflicted files belong to lidge-jun#7610 and take dev's squashed version (9a61bd9); the five lidge-jun#7688 files are unchanged from the reviewed head d06cf9b apart from dev's own edits to structure/config.md.
Summary
Catalog healing must compare directory entries without treating an ambiguous hardlink pathname as a proven match or a proven different target. On macOS, native realpath can report another hardlink name, which can interfere with release fences and cached observations.
This preserves the canonical parent and leaf identity for multi-link observations and adds a bounded
same / different / unknowncomparison with metadata revalidation. Admission and precommit accept onlysame; a possibly relatedunknownrelease fences healing. An unknown owner publication invalidates the generation without adopting a baseline or clearing the release latch, and unknown observations cannot reuse cached data.Windows native normalization, including 8.3 aliases, and ordinary single-link behavior are retained. The comparison uses at most 64 filesystem API calls and 40 symlink hops, with no directory enumeration or new dependency. These are operation bounds, not a wall-clock guarantee.
POSIX symlink targets now resolve intermediate directories before applying
..; missing and non-directory crossings remain unknown. Intermediate link identities are revalidated within the same budget. Windows keeps its native lexical path behavior. Regressions use distinct-file OS read/realpath oracles and include POSIX literal-backslash and file-link cases.Limits
Two different leaf names with the same parent and inode remain unknown on macOS, including real sibling hardlinks and case/Unicode aliases. This can defer healing unnecessarily. The comparison deliberately does not enumerate directories; entry relationships without bounded identity evidence remain unknown. This PR does not claim to resolve every alias or provide a physical-file-wide mutation fence.
Related runtime behavior: Bun #44550. That report is context, not proof that it caused every earlier CI failure.
Verification
Current candidate:
cf72010f480d607bdf390717c28f62be240b0981, a normal merge of the preserved9a6973a3composition and dev50afcec5. The six PR-owned files are unchanged from that composition; the three production and two test files remain byte-identical to the previously validated public192687bc.Runtime and configured test runner are both Bun 1.4.4. On the refreshed candidate, official Bun 1.4.4 on Windows passed:
Each selected case ran in its own process with the existing assertions and limits. Native exit, stdout/stderr completion and owned-child cleanup were recorded. The hop test uses its injected read seam to reach 40 hops independently of the production 64-read budget; it does not claim that the production comparator performs 160 reads.
Historical evidence at
192687bcremains separate: self-heal 100 pass / 2 POSIX-only skips / 265 assertions, heal integration 15 / 71, runtime 59 / 212, and successful cross-platform run 40109205588. Those unchanged-source observations were reused rather than rerun, and are not a full-suite result for this new composition.New exact-head CI is required before merge. Maintainer acceptance of the conservative availability tradeoff remains required. The existing Ready state is preserved; no live catalog, account, service, global configuration or application was changed.
