feat(path-guard): drift-resistant allowlist + centralized segment vocabulary#190
Merged
Conversation
…rom template@aeac8c1)
…te literal detection Sync from template@000943d. Hook + gate now flag template-literal build paths; allowlist replaces ±2 line tolerance with exact-line OR snippet_hash match. New --show-hashes flag prints SHA-256 prefix for allowlist entries that survive reformatting.
…ents.mts Sync from socket-repo-template@bb21ab5. Mantra: 1 path, 1 reference. Hook and gate now both import STAGE_SEGMENTS, BUILD_ROOT_SEGMENTS, MODE_SEGMENTS, and KNOWN_SIBLING_PACKAGES from a single canonical .claude/hooks/path-guard/segments.mts so they can no longer drift on what counts as a build-output path.
Pre-existing format drift in 7 files — collapsed multi-line array/arg literals where oxfmt would have inlined them. No semantic changes. Surfaced by the pre-commit hook running `oxfmt --check .` against the whole repo.

Summary
Propagates path-guard + token-guard updates from socket-repo-template@bb21ab5.
Mantra: 1 path, 1 reference. Every build/test/runtime path is constructed exactly once; everywhere else references the constructed value.
What's new
path.join-only scanner.snippet_hashmatch.snippet_hashis a 12-char SHA-256 prefix of the whitespace-normalized snippet, surviving reformatting but invalidated by content-changing edits.--show-hashesflag: print the hash for each finding when authoring an allowlist entry..claude/hooks/path-guard/segments.mts): stage / build-root / mode / sibling-package sets are now imported by both the hook and the gate from one canonical file. The two can no longer drift on what counts as a build-output path.Companion propagations
