…te Unreleased The families table and command table said the parent is verified with a verify line at commit time; the code checks liveness and holder at planning and updates the parent's refs from the record it read. The claim stanza was called exact but omits the ancestor-prefix verify and directory token. A release leaves the directory token behind, so the store is not empty. with accepts --parent and --note and optional paths. release accepts both --record and --acquisition (both must match), so they are not enforced as mutually exclusive. CHANGELOG had two [Unreleased] sections, the new one above the preamble. Refs #37

- Line 414: Update both README descriptions of `--wait` to state that retries
continue until requested paths and, when `--sem` is set, a semaphore slot are
available or the wait expires. Include the case where no paths are requested,
and keep the documented immediate-refusal behavior when waiting is omitted.

The single finding is fixed, CodeRabbit confirmed in-thread that the fix addresses it, and the thread is resolved. CodeRabbit's re-review is rate-limited, so this stale request is dismissed.

The introduction previously implied atomic visibility to readers and a reservation lasting for the entire wrapped command. It now leads with cooperative path reservations, explains acquire-before-launch ordering and TTL expiry, and distinguishes shared logical names across worktrees from shared physical files.
Introductory and wrapper transcripts were recaptured from the 0.7.0 executable in isolated stores, including acquisition and record IDs. The renewal example uses
showto verify the acquisition stayed constant while its record changed. The release reference now distinguishes--acquisitionfrom--record; historical storage sketches are explicitly abbreviated rather than presented as complete current payloads.Fixes #37.
Validation: ten complete displayed JSON lines parsed and validated against the public schema; executed contention, no partial acquisition, unrelated free path, renewal/release, and wrapper stream separation;
wide-md --check, normal commit lint, the full pre-push suite (452 passed, 0 failed), and published GitHublint-and-testpassed ond633087. Runtime code and schema are unchanged. The partial-observation investigation remains #38; this documentation does not claim that cached reads form a consistent cut or that external adoption has been demonstrated.
