+## Fail-Closed Execution & Explicit Simulation (SDLC-D-035)
+
+**Added:** 2026-08-17
+
+Forge fails closed when a required capability is missing. It never runs a
+pipeline with a stub executor and reports success.
+
+### Normal mode (default)
+
+- No task executor wired → the CLI exits nonzero with the typed capability
+  error `FORGE_NO_EXECUTOR`. No run is created.
+- A stage whose gate is approval-based (board approval, planning approvals,
+  remediation re-review, discovery/analysis attestations) records a typed
+  `waiting-for-authority` stage result and raises `FORGE_AUTHORITY_REQUIRED`.
+  It never passes vacuously.
+- A stage whose gate requires an unwired provider (AI reviewer, CI pipeline)
+  records a typed `blocked` stage result and raises `FORGE_NO_REVIEWER` /
+  `FORGE_NO_CI_PIPELINE`. The synthetic echo-review approval in `06-review`
+  and all vacuous `true` gates were removed.
+
+### Explicit simulation (`--simulate`)
+
+Opts into stub/synthetic execution. Every stage result, every gate result, and
+the run manifest carry the distinct typed status `simulated` (manifest also
+records `mode: "simulated"`). `simulated` is a non-satisfying outcome:
+`isSatisfyingOutcome()` and all completion/gate consumers treat only `passed`
+as satisfying. The CLI exits 0 for a simulated run only because the caller
+explicitly passed `--simulate`, and prints a loud SIMULATED banner.
+
+### Typed outcome model
+
+Every gate/task outcome is one of the closed set
+`passed | failed | blocked | error | waiting-for-authority | simulated |
+not-applicable`, with the reason recorded on the stage status and each gate
+result in `manifest.json`. Missing implementations, missing gate evidence,
+unknown stages, process errors, and timeouts map to fail-closed members —
+never to `passed`.

-# RI-1-002 — Publish-gate negative controls (SDLC-D-034 second half)
-
-- Task: RI-1-002 (docs/release-integrity workstream, PRD item RI-N1), issue ref #1275
-- Branch: `test/ri-050-publish-gate-negative` (base `origin/next` @ d8e0aec9 = PR #1277, RI-1-001)
-- Budget: worker estimate ~45K tokens; keep scoped to the two test files + scratchpad.
-
-## Objective
-
-Checked-in negative-control tests that PROVE the publish gate fails when it must:
-
-1. Broken mandatory check blocks every publish step (structural DAG proof from `.woodpecker/publish.yml`).
-2. Bypass shapes fail the checker: missing edge, hidden effect (non-`publish` name), detached verify, always-pass verify (`failure: ignore` / `success` override), conditional verify (`when`).
-3. Exact-commit identity: no HEAD-moving step between verify and publish effects; legitimate re-checkout requires verify to re-run after it.
-4. `verify-release.mjs` composition control: a SUBSET stage list fails the composition check.
-
-## Plan
-
-- NEW `scripts/publish-gate-structure.test.mjs` — self-contained structural checker (`assertPublishGateBlocksOnVerify`) + positive control on the real pipeline + one negative-control test per bypass shape (S1–S6, documented in file header) + positive control for the legitimate re-checkout shape.
-- EXTEND `scripts/verify-release.test.mjs` — refactor the stage-mirror test body into `assertStagesMirrorCi(stages, ci)`; add negative control dropping each stage one at a time (subset must throw).
-
-## Conventions confirmed
-
-- Root `test:checkout` = `node --test scripts/*.test.mjs` → new file auto-joins `pnpm test`.
-- Test-enumeration guard population is `*test*.sh` under `packages/mosaic/framework/tools/` only → unaffected.
-- Root eslint covers only `**/*.{ts,tsx}` → .mjs files need Prettier style only (printWidth 100, singleQuote, semi, trailingComma all).
-- Do NOT touch docs/TASKS.md, docs/release-integrity/TASKS.md, docs/scratchpads/.
-
-## Progress log
-
-- [x] Base verified: publish.yml `verify` step + verify-release.mjs present; HEAD contains origin/next.
-- [x] Wrote scripts/publish-gate-structure.test.mjs
-- [x] Extended scripts/verify-release.test.mjs (mirror fn + subset negative control)
-- [x] Gates: node --test scripts (31 tests pass), prettier clean on touched files, pnpm typecheck PASS, pnpm lint PASS, pnpm format:check PASS
-- [x] Committed ff585b88 + pushed, PR #1305 → next (no conflicts). Stopped before merge per task instruction.
-
-## Evidence
-
-- `node --test scripts/verify-release.test.mjs scripts/publish-gate-structure.test.mjs` → 31 tests, 0 fail.
-- Mutation sanity: temporarily removing the `verify` edge from build-gateway in publish.yml → structure test goes red (verified manually during dev, then reverted).
-- Gates run from repo root on this worktree; results in Progress log.
-
-## Risks / notes
-
-- Effect detection (`isPublishCommand`) is deliberately over-broad (any npm/pnpm/yarn command mentioning `publish`, any kaniko/docker-push/`--destination`) — fail-closed: a false positive forces justification, a false negative is the actual hazard.
-- `git fetch` flagged as HEAD-moving even though fetch alone doesn't move HEAD — fail-closed on the classic `fetch && reset` pair.

-// RI-1-002 / RI-N1 publish-gate NEGATIVE CONTROLS (SDLC-D-034).
-//
-// scripts/verify-release.test.mjs pins the POSITIVE structure of the publish
-// gate: every publish effect declares a direct `depends_on: verify` edge and
-// the verify step asserts commit identity + runs the canonical command. This
-// suite is the negative-control set: each test feeds a structural gate
-// checker a pipeline in which the gate is bypassed by ONE specific shape and
-// asserts the checker goes RED. The controls prove from the pipeline FILE —
-// never by executing Woodpecker — that a verify step that FAILS (nonzero
-// exit) blocks every publish effect.
-//
-// Woodpecker semantics these controls rely on:
-//   - A step that exits nonzero FAILS, and every step that transitively
-//     depends on a failed step is SKIPPED — never run. That skip is the only
-//     thing standing between a failed mandatory check and a publish effect.
-//   - `detach: true` removes the step from the wait graph: the pipeline does
-//     not wait for detached steps, so their failure can never block anything.
-//   - `failure: ignore` reports a failed step as success to the DAG.
-//   - `success: [codes...]` overrides which exit codes count as success;
-//     admitting any nonzero code launders a failed verification into green.
-//   - `when` on the verify step would skip verification entirely on some
-//     event/path classes while publish effects still run.
-//
-// Bypass shapes covered (one negative-control test each):
-//   S1  Missing edge — a publish effect whose dependency closure does not
-//       contain `verify` (a refactor drops the depends_on entry).
-//   S2  Hidden effect — a step whose NAME does not start with `publish` but
-//       whose COMMANDS publish npm packages or push images. Effects are
-//       classified by commands, so renaming a step cannot un-gate it.
-//   S3  Detached verify — `verify: { detach: true }`: publish steps no longer
-//       wait for verify, so the depends_on edge is decorative.
-//   S4  Always-pass verify — `failure: ignore`, or a `success` override
-//       admitting nonzero exit codes: verify fails, the DAG sees success.
-//   S5  Conditional verify — a `when`/path filter on verify itself.
-//   S6  Exact-commit drift — a HEAD-moving step (git checkout/switch/reset/
-//       clean/pull/clone/fetch) ordered between `verify` and a publish
-//       effect: the verified commit would not be the published commit. A
-//       LEGITIMATE re-checkout is allowed only when `verify` itself runs
-//       after it — positive control included.
-//   S7  Gate removal — the verify step deleted or renamed away entirely.

-// dependency) instead of adding a root dependency or vendoring a parser.
