Independent local Codex review PASS at 73b07f8d17, no P0/P1. Independent 66 tests and strict validation of 810 skills passed. CI run 34683976362 passed; all 48 current checks green. Incomplete memory reads fail closed with safe MCP diagnostics; canonical guidance synchronized across harness skill copies. Rollback: revert this squash commit. No deployment or installation claim.
ecc memory writes and --body-file reads fail on Windows. sameFileIdentity()
compares the dev field of a path-based stat against a handle-based fstat, and
libuv 1.49.0 through 1.50.x resolve path-based stat() and lstat() on Windows
through GetFileInformationByName, which leaves the volume serial unset while
fstat() reports it. The comparison never matches, so the TOCTOU guard rejects
every operation.
Keep the inode strict and compare dev only when both sides report one. POSIX
always reports a non-zero dev, so the original strict behaviour is preserved
there.
Request the guard's stats as BigInt. On the affected libuv versions dev is 0,
which leaves the inode as the only identity signal, and Windows file IDs run
past Number.MAX_SAFE_INTEGER where two distinct files can collapse to the same
number-valued inode.
Fixes#2626
Add a local-first, cross-harness memory vault with CLI and MCP surfaces, bounded search and storage, harness-scoped visibility, setup guidance, and comprehensive tests.
