# Self-Coherence — Cycle #334

> **RETROACTIVE RECONSTRUCTION** — This artifact was not produced during the cycle.

## Gap Statement

`cdd/issue/SKILL.md` had no guidance on cycle scope sizing. γ sized by intuition; no heuristic, no master+subs pattern codified.

## Mode

`design-and-build` — single new section in one file.

## Acceptance Criteria (reconstructed from PR #336 diff)

| # | AC | Status |
|---|---|---|
| 1 | `## Cycle scope sizing` section in issue/SKILL.md between mode declaration and next section | SHIPPED |
| 2 | AC-count bands (1–4/5–7/8–10/≥11) + five-factor heuristic (a–e) + master+subs pattern | SHIPPED |
| 3 | Scope-sizing template in minimal output pattern | SHIPPED |
| 4 | Handoff checklist row | SHIPPED |
| 5 | Empirical anchor from tsc#23 (cycles 24/25/26/29) | SHIPPED |

## Implementation

Claude Code (sonnet, session `mellow-atlas`, ~90s). Single commit, +62 lines, 1 file. Agent also modified `operator/SKILL.md` reverting the `--verbose` fix — caught during rebase onto main (my fix on main won). Clean after rebase.
