Remote durability checkpoint only — this draft PR is durable storage, not acceptance or a merge recommendation.

Preserves the exact authored working-tree blobs for entry #29, based on exact source HEAD 7498a678c52029a82f312e9637ecb66b15defa0b.

Validation performed before and after checkpoint:

  • root LICENSE is tracked, non-empty, and MIT
  • focused staged-patch gitleaks scan passed
  • staged blob hashes matched the source worktree immediately before commit
  • carrier commit parent equals the source HEAD
  • local HEAD, upstream tracking ref, and live git ls-remote SHA are identical
  • every remote tree blob matches the post-push source worktree byte-for-byte
  • carrier is clean and the original worktree was not edited

This branch is immutable archival evidence. Tests and review determine acceptance separately.

- Preserve field metadata when C recovery flattens invisible subtrees into ERROR nodes.
- Match locked C grammar behavior by avoiding error flags on visible absorbed leaves.
- Add parity coverage for the Issue 454 fixture at five source sizes.

Closed by the 2026-08-23 archive triage (wave 2). The C-guard test lands through PR #911. The parser_recover_c variant stays parked on the branch. The archive branch keeps the full state. See spore.2026-08-23.cedar.archive-sweep-disposition-wave2 in hypha://m31labs/gotreesitter.
