STEP 1  ──  Skill(skill="vibe", args="recent [--quick]")
              Use --quick for fast/standard. Full council for full.
              PASS/WARN? → continue
              FAIL?      → write summary, output <promise>FAIL</promise>, stop
                           (validation cannot fix code — caller decides retry)

STEP 1.5 ── Four-Surface Closure (mandatory)
              Read `skills/validation/references/four-surface-closure.md` for the mandatory four-surface closure check.
              Check all four surfaces: Code, Documentation, Examples, Proof.
              All 4 pass? → continue
              if --strict-surfaces:
                Any surface fails? → FAIL, write summary, output <promise>FAIL</promise>, stop
              else (default):
                Code passes, others fail? → WARN, continue
                Code fails? → BLOCK, write summary, output <promise>FAIL</promise>, stop

STEP 1.6 ── Test pyramid coverage audit (advisory, append to summary)
              Check L0-L3 + BF1/BF4 per modified file. WARN only, not FAIL.

STEP 1.7 ── Lifecycle Checks (advisory except critical dependency findings)
              Skip entire step if: --no-lifecycle flag.
              Each sub-step uses --quick mode to limit context consumption.
              On budget expiry: skip remaining sub-steps, write [TIME-BOXED].

              a) if lifecycle tier >= minimal AND test_framework_detected:
                   Skill(skill="test", args="coverage --quick")
                   Append coverage delta to phase summary.

              b) if lifecycle tier >= standard AND dependency_manifest_exists:
                   Skill(skill="deps", args="vuln --quick")
                   CRITICAL vulns (CVSS >= 9.0): **FAIL** (block shipping). Opt-out: `--allow-critical-deps` for acknowledged risk acceptance.
                   Non-critical: advisory note only.

              c) if lifecycle tier >= standard:
                   Skill(skill="review", args="--diff --quick")
                   Append review findings to summary as advisory.

              d) if lifecycle tier == full AND modified_files_touch_hot_path:
                   Skill(skill="perf", args="profile --quick")
                   Append perf findings to summary as advisory.
                   Hot path detection: modified files match benchmark files
                   or patterns (handler, middleware, router, parser, engine,
                   worker, pool, codec).

STEP 1.8 ── Stage 4: Behavioral Validation (holdout scenarios + agent-built specs)
            Skip if: no .agents/holdout/ AND no .agents/specs/, or --no-behavioral
            Read `references/step-1.8-behavioral-validation.md` for full sub-steps.
            Loads holdout scenarios + agent specs → evaluator council → satisfaction gate.
            Evaluates each scenario and aggregates results into `satisfaction_score`
            (verdict schema field, `skills/council/schemas/verdict.json`: number 0.0-1.0,
            "Probabilistic satisfaction score (0.0 = unsatisfied, 1.0 = fully satisfied)").
            Per-dimension scores populate `satisfaction_breakdown`. The aggregated
            `satisfaction_score` seeds downstream gates and the phase summary.
            PASS/WARN? → continue | FAIL? → <promise>FAIL</promise>, stop

STEP 2  ──  if epic_id:
              Skill(skill="post-mortem", args="<epic-id> [--quick]")
            else:
              Skill(skill="post-mortem", args="recent [--quick]")
              Use --quick for fast/standard. Full council for full.
              PASS/WARN? → continue
              FAIL?      → write summary, output <promise>FAIL</promise>, stop

STEP 3  ──  if not --no-retro:
              Skill(skill="retro")

STEP 4  ──  if not --no-forge AND ao available:
              if [ -n "${CODEX_THREAD_ID:-}" ] || [ "${CODEX_INTERNAL_ORIGINATOR_OVERRIDE:-}" = "Codex Desktop" ]; then
                ao codex stop --auto-extract 2>/dev/null || true
              else
                ao forge transcript --last-session --queue --quiet 2>/dev/null || true
              fi

STEP 5  ──  write phase summary to .agents/rpi/phase-3-summary-YYYY-MM-DD-<slug>.md
              ao ratchet record vibe 2>/dev/null || true
              output <promise>DONE</promise>
