+## 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`.

- * `mosaic store` — the vetted user store under `~/.mosaic/{plugins,skills}` (W-F4).
- *
- * Two roots with distinct ownership (HARNESS-HOMES design, frozen REV3):
- * - `~/.config/mosaic/` is the SYSTEM root: update-owned, replaceable wholesale.
- * - `~/.mosaic/` is the USER root: never touched by installs or updates.
- *
- * This module only ever writes under the USER root. The store is the vetting
- * boundary: content lands here only through an explicit `store add` carrying a
- * named vetting attribution, and every entry is versioned
- * (`store/<kind>s/<name>/<version>/`) with a `store-entry.json` marker written
- * LAST — a version directory without its marker is never a usable entry, and
- * an unmarked target is REFUSED by default: it may be this tool's own debris
- * from an interrupted add, or content the operator placed by hand, and the
- * code cannot tell those apart — so deletion happens only under an explicit
- * `--reclaim` opt-in, and the result status names what was done.
- *
- * Deferred by design (W-F6 and later): activation/symlink-install into agent
- * homes, `current`-pointer pinning, network acquisition. `add` accepts a local
- * source path only — no network, no credentials, ever.
