fix(fleet): activate the lease broker at install/start, place units through symlinks safely, refuse doomed launches (#1292 )

Wall 6: no documented path ever enabled or started the shipped mosaic-lease-broker.service — every gated runtime died ~4s in at lease registration while fleet start reported rc0, and a broker not in the reconciler plan could not be reported as drifted. Activation lands in the control plane, not the launcher: - fleet install places ALL FOUR units through placeUnitFile — a placement helper that unlinks any by-path-enable symlink at the destination BEFORE copying (Node copyFile follows the link and overwrites the SEED template; measured on a throwaway systemd user instance 2026-08-17, with both cp and fs.copyFile), removes a stale wants-symlink pointing outside the active dir (readlink — readFile returns the target's content, not the link path), then copies and daemon-reloads. The same measurement showed systemctl enable <name> does NOT rewrite an existing by-path wants-symlink — reconciliation must be explicit. Idempotent: second install on by-path residue converges to the identical state. Until now the copy block named three units and omitted the broker, and the residue set / copy set were disjoint only by accident (fomo-lin survived copy-through because its one symlink was the one unit not copied); adding the broker made them intersect on first run. See the SET-INDEPENDENCE note on the helper before adding a fifth unit. - enableFleetUnits enables the broker first, alongside the holder. - fleet start / reconciler start the broker BEFORE any holder/agent lifecycle effect, then RE-CHECK the socket (not unit state) and exit nonzero with a named code if it did not appear. Re-probed on every invocation — a RemainAfterExit=yes dead-looking-active unit can never make retry look like repair (the sticky-retry check). - The reconciler plan carries broker {unitInstalled, socketPresent} as a first-class member; the socket is the signal (enabled-but-dead units report socketPresent=false). - start-agent-session.sh preflights the broker socket BEFORE any tmux effect (moved ahead of the ownership probe): absent -> exit 75 (EX_TEMPFAIL), named refusal with socket path and remedy, no doomed pane. The agent@ unit is Type=oneshot with no Restart=, so the message survives instead of looping. The preflight detects and refuses; it never starts the broker. - mosaic doctor's lease check names one convention-neutral remedy: 'mosaic fleet install (it reconciles either enable convention)' — written from the measurement; teaching a manual systemctl line could leave a host with competing wants-symlinks. Tests: fleet-place-unit.spec.ts (8: clean-host negative control, by-path residue -> seed bytes AND mtime unchanged [the finding-2 check], wants-residue cleared, idempotence single + double-install convergence); fleet.spec.ts broker-first enable ordering, refused start emits no holder/agent calls, second-start re-probe; reconciler broker plan member (enabled-but-dead shape) + broker-before-agent ordering in both command and apply paths; test-agent-session-broker-preflight.sh (CI-fit: fake tmux, real unix socket at a short /tmp path — AF_UNIX caps at 108 bytes, hermetic env; absent -> exit 75 + no tmux session, live socket passes, explicit env wins, --stop not fenced). 1563/1563 vitest, lint, root build 25/25, root typecheck 45/45. Sabotage controls: placement unlink removed -> exactly the seed-integrity test reddens (1/8); socket re-check disabled -> exactly the two preflight specs redden; shell preflight removed -> the bash suite reddens (6 FAIL assertions, rc=1). All restored byte-identically (sha256-verified), all green again. Test 6 (greenfield 1124, seat alive 2min + second fleet start) runs on sandbox after daphne's baseline, coordinated with fred. Note: the preflight uses exit 75 measured against the unit's Restart= policy (oneshot, none) — no restart loop.

 ## 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`.

 # CI-fit regression suite for the #1292 lease-broker socket preflight in
 # start-agent-session.sh.
 #
 # WHY THIS SUITE IS CI-FIT WHERE test-start-agent-session.sh IS NOT (#1017/#1270
 # context): that older suite's precondition is "the host does not have the pi
 # binary", which a CI image that ships pi violates — its guard correctly
 # refuses to report a pass there, so it is excluded from the chain. THIS suite
 # controls its own preconditions instead of inheriting them from the host: a
 # fake tmux on PATH, a fake mosaic on PATH, a real unix socket created in a
 # tmpdir, a hermetic env (env -i, fake HOME, GIT_CONFIG_GLOBAL severed). It
 # never depends on what the host has installed, so a green here means the same
 # thing on every host. Anyone adding cases: keep that property — no case may
 # depend on host state.
 #
 # The failure this suite is written down to catch (#1292): a seat launched on a
 # host with no lease broker dies ~4 seconds in at registration, with the
 # diagnostic invisible because tmux destroys the dead pane. The preflight runs
 # BEFORE any tmux effect and refuses with a NAMED code (exit 75, EX_TEMPFAIL)
 # so the message survives. The agent@ unit is Type=oneshot with no Restart=,
 # so a failed unit keeps its output instead of looping.
 #
 # Cases:
 #   1. absent socket -> exit 75, message names broker-absent + socket path +
 #      remedy, and NO tmux session was ever created (the doomed-pane half).
 #   2. present socket (real unix socket in tmpdir) -> proceeds PAST the
 #      preflight (the suite then stops at the next precondition, proving the
 #      preflight was not the refusal).
 #   3. explicit MOSAIC_LEASE_BROKER_SOCKET wins over XDG_RUNTIME_DIR default.
 #   4. --stop mode does NOT require the broker (teardown must not be fenced on
 #      a component whose absence is exactly what teardown may follow).
 #
 # Sabotage control, run by the developer (not in-suite): remove the preflight
 # block from start-agent-session.sh, re-run — case 1 fails (a tmux session is
 # created / exit is not 75), cases 2-4 still pass; restore byte-identically.

 *     acceptance asserts on the RESULTING SYMLINK TARGET, never on the enable
 *     call's argument (asserting the call cannot see where the link ended up).
 *  2. Node's copyFile FOLLOWS a by-path symlink at the destination and
 *     overwrites the SEED template. Acceptance asserts on the SEED's bytes
 *     AND mtime — unchanged — which is the only check that can redden for
 *     finding 2. The symlink-target assertion catches finding 1; these are
 *     different defects with different failure modes.
 *
 * Fixtures are entirely inside tmpdirs (source template, active systemd dir,
