             --diff-base must be the merge base with --base, default origin/HEAD's branch, on every pass)
      writes <out>/<role>[-<name>].prompt.md, records it in the ledger (default <out>/review-ledger.jsonl) and prints
      BRIEF: reader=<role/name> sha256=<h> bytes=<n> file=<path>. Pass that file's content as the reader's prompt, unchanged.
  sent --ledger <f> --role <role> [--name <n>] --sent <file>
      the exact prompt a dispatch passed: BRIEF_SENT: … match, or BRIEF_MISMATCH: … (exit 1; the pass is not reviewed)
  collect --ledger <f> --role <role> [--name <n>] --output <file> --merged <merged.jsonl>
      the reader's raw output: hashes it and appends each finding to merged.jsonl with its label as written. A reply with
      no finding must carry its brief's clean marker (NO FINDINGS; the Recommendation: line for the voices); without one it is
      COLLECT_NOT_REVIEWED (exit 1): a refusal, an empty reply or a reader that never saw the diff, and verify reports NOT_COLLECTED
      until the brief is re-sent and answered with a review, which voids it. --unavailable '<reason>' (the outside voice only; refused when the
      output holds findings) records its failure text as missing coverage: COLLECT_UNAVAILABLE, and verify prints UNAVAILABLE and unavailable=N, never a review
  judge --ledger <f> --merged <merged.jsonl> --judged <judged.jsonl>
      judged lines {"id","severity","reason"?,"duplicate_of"?}: every merged id kept at its severity or above (a
      duplicate folds into one at least as severe); added and promoted findings need a reason. JUDGMENT: ok …, or
      JUDGMENT_REJECTED: dropped=… downgraded=… (exit 1)
  verify --ledger <f> [--targeted-out <file>]
      BRIEF, OUTPUT and JUDGE rows from the ledger alone, then VERIFY: clean (exit 0), VERIFY: dirty (exit 1) or
      VERIFY: no brief records (exit 3: this run's ledger kept no prompts). A ledger with a targeted brief also prints
      TARGETED_RECORD: and --targeted-out writes it as the JSON gstack-ship-receipt write --review-targeted reads
  pass --base <ref> --out <dir> --pass <id> [--ledger <f>] [--diff-base <sha>] [--learnings-file <f>] [--extras <json>]
       [--checklist-root <dir>] [-- <gstack-review-plan flags>]
      runs gstack-review-plan and writes <out>/pass-manifest.json: stage first (audit readers marked first in --extras),
      specialists (with the other --extras readers), red-team, voices (Step 11). Renders first and specialists now; prints
      the plan, MANIFEST: and one READER: line per reader. A plan whose NEXT is not full or scoped prints PASS: none.
      An existing manifest for the same --pass is reused (resumed). --extras: [{"name","prompt_file","first"?,"model"?}]
  show --manifest <f>                         MANIFEST_JSON: <the manifest on one line>
  stage --manifest <f> --stage <first|specialists|red-team|voices>
      renders a stage; the Red Team only after every earlier reader is collected, its findings file being the
      specialists' merged.jsonl lines byte for byte
  chunk --manifest <f> --reader <r> --index <i>
      BRIEF_CHUNK: reader=… index=i of=n sha256=…, then one JSON string line of at most 65,536 brief characters
  mark --manifest <f> --reader <r> --state <intent|created|queued|collected|failed> [--path <p>] [--output <f>] [--error <e>]
  mark --manifest <f> --before <tokens>,<credits>
  mark --manifest <f> --log-start <key> --token <t>   records a review-log start token once, so a rerun starts only what is missing
      reader states move forward only; intent is recorded before the subagent is created, its path right after
