Closed by the 2026-08-23 archive triage. The P17 attribution test lands through PR #911. The arena edit stays parked on the branch. The archive branch keeps the full state. See the disposition spore spore.2026-08-23.cedar.archive-sweep-disposition in hypha://m31labs/gotreesitter. |

Durable remote checkpoint of exact authored worktree state from audit entries 43 and 44; entry 44 is a strict blob superset and shares entry 43's exact base and overlapping blobs. Storage only—not acceptance or merge readiness. Root OSS license present, focused gitleaks clean, and local/tracking/remote plus every preserved blob verified exact.
