## Self-coherence

See [`self-coherence.md`](self-coherence.md). All 9 ACs PASS by mechanical or read-check verification.

## Authoring judgment calls (from gamma-scaffold.md §J1–§J4)

- **J1 (HANDOFF.md present-or-absent):** Omitted; `.gitkeep` placeholder. β APPROVED.
- **J2 (extraction-map source paths post-#411):** Recorded each row at its current canonical home (some in cnos.cdd, some in cnos.cds). Flagged migration-semantics-undecided rows for sub dispatchers. β APPROVED.
- **J3 (operator §3a deprecation):** Used `delta/SKILL.md §2` as the canonical source pin; noted §3a redirect. β APPROVED.
- **J4 (additional discovered surfaces):** Recorded polling primitives (§7) and spec-staleness propagation (§8) as additional rows; folded bundle file sets into Sub 2's wholesale move. β APPROVED.

## Hand-off

β review at [`beta-review.md`](beta-review.md): APPROVE R1.
