Codex's own post-mortem of the second hamster-wheel session: it loaded
the kicker ban, shipped five kickers anyway, and then the reviewer and
documenter 'compounded it by accepting, and even canonizing, the
invented label style'. Nothing downstream of the builder ever re-read
the floor.
The reviewer gains check 6, Floor: read craft-floor.md (now the one
skill reference it may read, passed in its inputs) and hold the
screenshots against the Refuse list; a banned element is a material fix
even when it matches nothing in the comp, because fidelity cannot
authorize what the floor refuses. The documenter gains the mirror rule:
a floor refusal lands in its not-canonized line as a carried defect,
never in DESIGN.md as a rule future surfaces inherit.
Also updates the live-reference contract test to match the applier's
condensed no-server sentence, which still carries the same guarantee.

Raising the reviewer's turn budget did not change its fate, only its
reading: 43 tool uses instead of 22, still reaped mid-read with nothing
written, because the SDK ends a run at max-turns without warning and the
model never feels the deadline. The definitions now carry the deadline
themselves: reading is an allowance, batch Reads per turn, take the
decisive inputs first, sample instead of walking the tree, and write by
mid-budget, naming what went unread. A review built from what you saw
beats a perfect review that never arrives.

A finish review reads the artifact, two full-page screenshots, the
approved comp, the quality-bar cards, and the contract before it may
write a word; at max-turns 12 the SDK reaps it mid-read and the parent
receives the opening sentence as the whole review. Observed twice in a
row (spawn and respawn) on the first real subagent run. The documenter
reads at least as much, and the asset producer pays per asset.

From the paired Opus and Codex manual-run analyses. DESIGN.md moves to
the end of the flow and into a shipped documenter subagent that derives
the system from the built artifact: a rulebook written before the build
gets defended against reality, and a half-stable DESIGN.md hands the
design-system detector an unstable target that buries the build in
noise and invites laundering. The finish reviewer gains the handoff
that failed three times live: the parent captures desktop and mobile
screenshots and passes paths, the reviewer never attempts to render
and names missing inputs in one line, the parent verifies the
five-section return and respawns once on empty. Fidelity against the
approved comp joins its checks; the card keeps commitment only. The
comp ingredient inventory becomes a written gate with raster-by-default
materials and no gradient-as-texture, comps persist under
.impeccable/mocks, the degraded seed names the sandboxed-exec cause,
and the finish line is explicit: a clean detector pass is not finished.
