M07 Audit — Opts Snapshot Introduction
Milestone: M07
Title: Opts snapshot introduction
Branch: m07-opts-snapshot
Audit date: 2026-03-12
Mode: DELTA AUDIT
Range: 6744152a (M06) → 8ea50d35 (M07 merge)
CI Status: Green (Quality 22983583947)
Refactor Posture: Behavior-Preserving
Audit Verdict: 🟢 Milestone objectives met. Infrastructure preparation; no runtime behavior change. Proceed to M08.
1. Executive Summary
M07 successfully introduced the opts snapshot mechanism for generation runs, establishing the third Phase II runtime seam.
Wins:
create_opts_snapshot(opts)returns a deterministic snapshot of opts.data- Snapshot captured in
process_images_innerafterprepare_prompt_seed_state(p)— post-override, post-prep - Full shallow copy of opts.data; no filtering (avoids omission risk)
- Snapshot stored on
p.opts_snapshot; write-only in M07 (no reads replaced) - Minimal blast radius: only
modules/opts_snapshot.py(new) andmodules/processing.py(modified) - txt2img and img2img smoke tests exercise the critical path
Risks: None identified.
Next action: Proceed to M08 (snapshot threading into process_images_inner).

3. Delta Map & Blast Radius
| Changed | Impact |
|---|---|
| modules/opts_snapshot.py | New — create_opts_snapshot(opts) |
| modules/processing.py | Modified — capture snapshot after prepare_prompt_seed_state |
| docs/milestones/M07/* | Plan, toolcalls, run reports |
Blast radius: Snapshot capture path only. No API/CLI/schema changes. Extensions and runtime continue reading shared.opts; p.opts_snapshot not yet consumed.
4. Category Scores
| Category | Score | Notes |
|---|---|---|
| Refactor discipline | 5 | Infrastructure-only; boundaries respected |
| Behavior preservation | 5 | No runtime drift; smoke + quality pass |
| Test coverage | 5 | Existing smoke tests cover critical path |
| CI integrity | 5 | All gates green |
| Overall | 5.0 |
5. Verdict
Milestone objectives met. Opts snapshot captured for generation runs. Third Phase II seam; enables M08 snapshot threading and removal of shared.opts dependency from the generation pipeline.
