+*Narrowed 2026-09-25 (S7 scoping).* The gate first listed F1, F2, F4, F8,
+F10–F15, F18 and F27. Layer A already runs every one of them in CI against
+the reference host. Layer B asks a different question: does a real host
+follow the prose? One scenario per invariant answers it:
+
+- F1: a worker does not accept its own work (I-1);
+- F2: pickup does not trust a forged `accepted` line after a crash (§13.2);
+- F11: an interrupted launch window is never taken as "not launched"
+  (§8.1);
+- F14: a crash between verdict and projection is repaired only after the
+  re-checks of §13.3. The real-host run covers both the changed-task case
+  (the verdict stays historical) and the changed-artifact case (the digest
+  no longer matches). `projected` checks the persisted verdict, the
+  checkbox and the attempt line, but it recomputes neither digest and runs
+  no check. So these re-checks are host prose that only a real host can
+  prove it follows;
+- F18: a surviving descendant blocks a stop and a second writer (§8.3, I-12);
+- F27: routing respects an owner-mandated executor (§17).
+
+The other Layer B scenarios (F4, F8, F10, F12, F13, F15) move to
+post-release evidence under `docs/evidence/v0.5.x/`. F14 was added back in
+review ([#22](https://github.com/vunm-io/passdown/pull/22)).

+- Acceptance: the Layer B scenarios in the §20.2 release gate pass;

+- **Owner attestation is the v0.5 cost (decision 2026-09-25).** The measured
+  cards (S6) show that no shipped executor gives safe machine stop evidence
+  on macOS. Claude Code and Codex tool shells survive `SIGKILL`; kiro-cli
+  could detach through a trusted shell. So every delegated attempt ends with
+  a person confirming that no process remains, unless it ran in a
+  containment scope. v0.5 ships this cost and documents it in the README
+  and release notes, and does not weaken §8.3 to avoid it. Lowering the cost
+  is v0.6 work: a containment scope on macOS, or measured evidence that a
+  normal (not killed) exit leaves nothing behind.
+- **Who attests in Layer B.** The owner, by hand, during each real-host run.
+  The harness may pause and show the process listings, but it never records
+  `owner-attested` itself (the rule #21 applied to the measurement runner).
+  The narrowed gate keeps this to six scenarios.
