## Gate F1–F10 verdict (per CDS.md §Gate)

For a docs-only cycle with no test/build/schema surface:

| Gate | Description | Result |
|------|-------------|--------|
| F1 | Issue closed-out artifact set complete | PASS (six close-out files + INDEX row) |
| F2 | Validation oracle passed | N/A (docs-only; no V predicate; mechanical AC checks substitute) |
| F3 | AC verification mechanical | PASS (8/8 ACs verified above) |
| F4 | No regressions | PASS (hard-rule diffs all zero) |
| F5 | Implementation-contract coherence | PASS (D1 delivered at canonical path; no scope creep) |
| F6 | Evidence-binding | PASS (every cited cycle linked to issue + path/SHA) |
| F7 | γ close-out artifact set | PASS (this file + siblings under `.cdd/unreleased/412/`) |
| F8 | Release-effector readiness | N/A (no release-shaped output; docs disconnect at merge) |
| F9 | Receipt-stream eligibility | PASS (`cdd-iteration.md` courtesy stub + INDEX row filed) |
| F10 | Closure verification | PASS (all preceding gates green) |

## Findings

None. Zero round-2 iterations.

## Round count

R1 only.

β hands off to γ for final close-out + INDEX row.
