Approve the submitted phase

Output contract: Reuse exact same-chat document displays; refresh packet review and explicit consent. For suggested actions, pair Shell with the returned Copilot command; honor commandGuidance. If absent, say "Copilot: no verified equivalent"; never invent a slash command.

Boundary: singularity-flow session current --json → ready/workId, cwd=repositoryPath; use CLI/workItemRoot paths; never $HOME.

Approval-only: An explicit human phase ID confirms only the unchanged packet already reviewed in this conversation. The approval CLI is the sole permitted lifecycle mutation. Never edit repository files, run tests/builds/raw Git, delegate, submit, or begin/author another phase. A failed approval ends this turn.

1. A positional argument selects PHASE-ID, never Work ID; Story comes from session or --work-id. Run singularity-flow choices begin approve <WORK-ID> --fetch --json. Require supplied phase = approvalContext.phase.
2. Run singularity-flow phase show <phase> --json. Match reviewBinding to receipt: repository/HEAD, Work ID, phase/generation, source commit, packet hash. Match artifacts/brief documentId, documentPath, and documentSha256 to approvalContext; brief path is integrity JSON. Only fallback-whole may lack a brief. Missing binding/mismatch: stop. Do not perform a second singularity-flow documents view lookup.
3. Render once per exact display binding. Retain displayBinding and reviewBinding. Reuse bodies only from a complete visible same-chat display with exactly matching non-null displayBinding. New chat, changed/null binding, omissions or truncation require full display. Render all text/briefs between --- BEGIN <path> --- and --- END <path> --- with ID/kind/path/bytes/generation/SHA-256, across messages if needed. Binary: path/metadata/open instruction. Tool output or summaries are not review. Truncated content: stop. Always show the current reviewBinding; body reuse never reuses approval consent.
4. Show current identity/authority, agent, checks/usage, decisions and self-approval warnings; unauthorized identity stops.
5. A human /sf-approve <PHASE-ID> or exact phase answer after complete review of this exact reviewBinding is <TYPED-PHASE>: do not ask again. Otherwise ask for the exact phase ID and wait. A phase supplied before a new or changed packet review is not its confirmation, even if document bodies match. Run singularity-flow choices answer <TOKEN> phase-confirmation <TYPED-PHASE> --json, then singularity-flow approve <TYPED-PHASE> --work-id <WORK-ID> --fetch --selection-receipt <TOKEN> only when ready: true. Never add --yes; the receipt is consumed once.
6. Refusal: relay and stop; human owns continue. No commit/publication proof: unverified. Report commit/push, reviewer/authority, assurance, threshold and next phase. The approval CLI advances and activates the next phase when the threshold is met; no second advance. Relay Context boundary and Next Copilot actions as display-only handoff; end this turn before next-phase authoring.

TRP: read and follow singularity-flow explain test-recovery; returned legal actions only.
