  next    --out <dir> [--plan <file>] [--plan-heading <text>] [--scaffold] [--ui|--no-ui] [--developer-tool] [--agent-primary] [--no-dx]
          [--no-outside] [--light] [--spend-cap <usd>] [--estimate-usd <n>] [--deadline <min>] [--redispatch <attempt>] [--json]
          --scaffold (first next): a plan missing one of its two sections is reviewed from <out>/plan-source.md with the heading added
          --light loads each phase's checklist plus the sections its scope needs (the unattended default); interactive kinds load everything
          prepare the current phase; one ATTEMPT: line per voice; ends awaiting_result
  submit  --out <dir> --phase <p> --voice native|outside --result <file> | --record <file> [--attest <reason>]
          --model <id> [--attempt <id>] [--runner <r>] [--usage-usd <n>] [--reconcile <jsonl>] [--json]
          bind one reviewer result (receipt, canonical findings, model family) exactly once; closes the phase when both voices are in.
          --attempt may be omitted when exactly one attempt is open. --record takes a hand-run review: the gstack-findings fence,
          one findings table (Severity and Title columns), one severity-tagged list (- [High] title) or a "No findings." line;
          without its INPUT line it binds only with --attest <reason> and --attempt (receipt: attested)
  submit  --out <dir> --phase <p> --voice outside --unavailable <reason> | --failed <reason>
          the outside voice could not run: closes the phase native_only once native is bound
  revise  --out <dir> --plan <file> [--incorporates <id,...>] [--withdraw <id>] | --settle <id,...>
          review a revised plan in this run: every phase whose reviewed Implementation-plan hash differs reopens (Eng last);
          --incorporates discharges the named accepted changes (the plan must change); --withdraw (alone or with --plan) drops one;
          --settle records a packaging/ordering change that needs no plan edit and reopens nothing (ids: decision id or d4)
  run     --out <dir> --plan <file> --native-model <id> --outside-model <id> [--runner codex-cli|api] [--native-runner api] ...
          next in a loop, only when a runner executes both voices here; --deadline cancels the children it started
  answer  --out <dir> --gate-rev <rev> --reply "<rec | rec except d3a | d3b uc1a | as-is>" --by <human|agent:<id>> [--json]
          --by agent:<id> needs --owner-reply "<owner's words>" (- reads stdin; --owner-reply-file <path>), stored verbatim;
          --rec-hash <h> binds a rec to the render the owner saw (required once recommend ran); accepted changes leave amend_pending
  recommend --out <dir> --gate-rev <n> --item <id> --option <k> --basis "<why>" [--by <who>]
          set one item's recommendation before relay (provenance recorded, p1 follows); re-render and relay afterwards
  resume  --out <dir> [--from <checkpoint>] [--json]   --from restores a hash-verified checkpoint into an empty --out first
          (a collection or root restores its newest valid generation; GSTACK_AUTOPLAN_CHECKPOINT_DIR set: every command
          leaving the run at rest publishes a generation under <dir>/<run>/ and prints CHECKPOINT: on stderr)
  checkpoints --from <dir>          list checkpoint generations, newest first: run, gate_rev, time, hash ok|bad, current
  status  --out <dir> [--json]      export  --out <dir>      release --out <dir> --attempt <id>
  contract                          print lib/coordinator-contract.ts (the block every lane and reviewer prompt inherits word for word)

The first next needs --plan. The native voice is dispatched by the parent from the printed prompt file (a subagent on the
parent's model); the outside voice runs through gstack-outside-voice or a cross-family subagent. Spend by host subagents is unknown.
The first next reads codex_reviews: disabled (or an unreadable config) records every phase's outside voice as a terminal
not_run consent_missing outcome and dispatches none. Enable: gstack-config set codex_reviews enabled.
