Require complete design artifacts at the finish handoff

Name token-bearing DESIGN.md and its sidecar in the parent handoff while shortening the paragraph. Keep spec, token, sidecar and write-boundary gates; report wrapper coverage separately.

Validation: one Claude redesign retest wrote both artifacts; saved-output replay passed artifact checks (live assertion first failed on wrapper coverage). Default tests, source build and skill validator passed. Remaining token-accuracy limitations are documented.

AI assistance: Codex, under maintainer direction.

 Report the final verdict under the reviewer's own disposition word and at its actual scope. A verdict pass scores the listed fixes and nothing else: "the reviewer scored all three fixes resolved" is a claim it supports, "no material issues remain" is not. A table with open material findings is never announced as a pass, never softened, and never dressed as whole-surface approval when only a fix list was scored. When the user answers a ship with evidence against it, their own screenshot, a named mismatch with the comp, that evidence outranks every capture you made: put their material in the packet and spawn a fresh reviewer for a new full review. Patching inline and self-certifying is how a rejected page ships twice. <!-- rule:skill-user-evidence-reopens-review -->

Without subagents, load and follow [degraded/documenter.md](degraded/documenter.md). An existing DESIGN.md does not skip this pass: compare the finished build with the recorded system; unchanged files are a valid result, reported with what was checked.

+### Targeted redesign handoff correction
+
+The parent handoff now explicitly requires token-bearing DESIGN.md and
+`.impeccable/design.json` for approved system changes and verifies those outputs
+before completion. It is nine words shorter; the agent and schema files did not
+change. One unchanged-assertion Claude retest finished in 65s: it read document.md
+and wrote both artifacts, but still skipped the degraded wrapper, so that
+reference assertion failed before the artifact assertions ran.
+
+Wrapper coverage is now diagnostic for all post-review modes; successful spec
+and source reads, completed turns, write boundaries, tokens, and the v2 sidecar
+remain hard gates. Offline evaluation of the saved retest passes these artifact
+checks; the original prose-only/missing-sidecar trace remains rejected. Negative
+controls cover absent tokens, malformed/missing sidecars, old schema versions,
+and absent metadata. This is replay, not a second live pass or a rerun of the
+cleaned-up workspace's byte-preservation checks.
+
+Artifact audit: the sidecar component renders correctly in an offline browser.
+The heading line-height was recorded as 1.3 while the page inherits 1.6 (38.4px
+at 24px), and generatedAt used a placeholder date. These are remaining output
+accuracy limitations, distinct from the corrected missing-artifact failure;
+the shape checks do not establish complete token fidelity. No broad provider or
+full-build rerun was purchased. Build and generated-skill validation passed.
