+# M08 Audit — Opts Snapshot Threading
+
+**Milestone:** M08  
+**Title:** Opts snapshot threading  
+**Mode:** DELTA AUDIT  
+**Range:** 8ea50d35 (M07) → 710a0abd (M08 merge)  
+**CI Status:** Green (Quality 22984445599)  
+**Refactor Posture:** Behavior-Preserving  
+**Audit Verdict:** 🟢 Milestone objectives met. Runtime now reads from p.opts_snapshot for save-related settings. Proceed to M09.
+
+---
+
+## 1. Executive Summary (Delta-First)
+
+**Wins:**
+* Migrated 12 save-related opts reads from shared.opts to p.opts_snapshot in process_images_inner
+* Limited blast radius to process_images_inner only; save_samples(), sample_hr_pass(), create_infotext(), metadata logic unchanged per M08 scope
+* Same inputs → same outputs; no behavior drift; smoke + quality tests pass
+* Fourth Phase II runtime seam; first deterministic runtime boundary for config reads
+
+**Risks:** None identified.
+
+**Next action:** Proceed to M09 (execution context seam).
+
+---
+
+## 2. Delta Map & Blast Radius
+
+| Changed | Impact |
+|---------|--------|
+| modules/processing.py | Modified — p.opts_snapshot for save-related reads in process_images_inner |
+| docs/milestones/M08/* | Plan, toolcalls, run1, run2, audit, summary |
+
+**Consumer surfaces touched:** None. API, CLI, file formats, extension API unchanged.
+
+**Blast radius:** process_images_inner image/grid saving logic only. Breakage would show up in: image save paths, grid save behavior, mask save/return, format selection. All exercised by smoke tests.
+
+---
+
+## 3. Architecture & Modularity Review
+
+* **Boundary violations:** None. Snapshot threading respects existing module boundaries.
+* **Coupling added:** None. p.opts_snapshot already existed from M07; M08 adds reads only.
+* **Dead abstractions:** None.
+* **Layering leaks:** None.
+
+**Keep:** Current structure. **Fix now:** None. **Defer:** None.
+

+# M08 Summary — Opts Snapshot Threading
+
+📌 Milestone Summary — M08: Opts Snapshot Threading
+====================================================
+
+**Project:** Serena  
+**Phase:** Phase II — Runtime Seam Preparation  
+**Milestone:** M08 — Opts snapshot threading  
+**Timeframe:** 2026-03-11 → 2026-03-12  
+**Status:** Closed  
+**Baseline:** 8ea50d35 (M07 merge)  
+**Refactor Posture:** Behavior-Preserving
+
+---
+
+## 1. Milestone Objective
+
+M08 existed to thread `p.opts_snapshot` into the generation runtime for safe read-only option access. M07 introduced the snapshot (write-only); M08 migrates the first set of reads from `shared.opts` to `p.opts_snapshot`.
+
+**What would remain unsafe or ungoverned if this refactor did not occur?** The runtime would continue reading directly from global `shared.opts` during generation, preventing deterministic isolation and blocking the ProcessingRunner architecture (M10+).
+
+---
+
+## 2. Scope Definition
+
+### In Scope
+
+* `modules/processing.py` — process_images_inner() for save-related opts reads
+* Migrated options: save_images_before_face_restoration, save_images_before_color_correction, samples_format, return_mask, save_mask, return_mask_composite, save_mask_composite, grid_only_if_multiple, return_grid, grid_save, grid_format, grid_extended_filename
+* CI: Linter, Smoke Tests (PR), Quality Tests (post-merge)
+* Documentation: M08_plan.md, M08_toolcalls.md, M08_run1.md, M08_run2.md
+
+### Out of Scope
+
+* save_samples(), sample_hr_pass(), create_infotext(), Processed.__init__(), fill_fields_from_opts()
+* modules/images.py
+* Override logic, UI/API option behavior, extension access to shared.opts
+* New runtime abstractions
+
+---
+
+## 3. Refactor Classification
+
+### Change Type
+
+**Mechanical refactor** — Replace `opts.foo` with `p.opts_snapshot.foo` for save-related reads. No logic change; same values at capture time.
+
+### Observability
+
+* **API responses:** Unchanged (txt2img/img2img JSON schema unchanged)
+* **CLI output:** Unchanged
+* **File formats / save paths:** Unchanged (p.outpath_samples, p.outpath_grids set before process_images_inner; format from snapshot)
+* **Model outputs:** Unchanged
+
+---
+
+## 4. Work Executed
+
+* Replaced 12 opts reads with p.opts_snapshot reads in process_images_inner
+* No functional logic changed; values identical at snapshot capture time
+* No new modules; no migration steps
+* Files changed: modules/processing.py, docs/milestones/M08/*
+
+---
+
+## 5. Invariants & Compatibility
+
+### Declared Invariants (must by default Not Change)
+
+* Generation behavior unchanged (same inputs → same outputs)
+* File output behavior unchanged (save paths, naming)
+* Extension compatibility (shared.opts still exists)
+* API compatibility (txt2img/img2img)
+* CLI behavior unchanged
+
+### Compatibility Notes
+
+* Backward compatibility preserved: Yes
+* Breaking changes introduced: No
+* Deprecations introduced: No
+
+---
+
+## 6. Validation & Evidence
+
+| Evidence Type | Tool/Workflow | Result | Notes |
+|--------------|---------------|--------|-------|
+| Linter | ruff, eslint | ✓ | PR #24 |
+| Smoke Tests | pytest test/smoke | ✓ | PR #24, run 22984306614 |
+| Quality Tests | pytest test/smoke test/quality | ✓ | Post-merge 22984445599 |
+| Coverage | ≥40% gate | ✓ | Quality Tests |
+| verify_pinned_deps | scripts/ci/verify_pinned_deps.sh | ✓ | Quality Tests |
+| pip-audit | Informational | ⚠ | Deferred M27 |
+
+---
+
+## 7. CI / Automation Impact
+
+* Workflows affected: None (unchanged)
+* Checks added/removed: None
+* Enforcement: Unchanged
+* Signal drift: None observed
+
+CI blocked incorrect changes (would fail if snapshot missing or wrong). CI validated correct changes (smoke + quality pass).
+
+---
+
+## 8. Issues, Exceptions, and Guardrails
+
+No new issues were introduced during this milestone.
+
+---
+
+## 9. Deferred Work
+
+* pip-audit vulnerabilities: Pre-existing from M04; deferred to M27. Status unchanged.
+
+---
+
+## 10. Governance Outcomes
+
+* Runtime seam stack now includes snapshot threading: fourth Phase II seam
+* First deterministic runtime boundary: generation pipeline reads save-related config from p.opts_snapshot
+* Invariants preserved and verified by CI
+
+**What is now provably true that was not provably true before?** The generation runtime reads save-related options from a deterministic snapshot (p.opts_snapshot) rather than global shared.opts within process_images_inner.
+
+---
+
+## 11. Exit Criteria Evaluation
+
+| Criterion | Status | Evidence |
+|-----------|--------|----------|
+| Snapshot used in generation runtime | Met | p.opts_snapshot.foo in process_images_inner |
+| Safe options migrated | Met | 12 opts migrated |
+| CI fully green | Met | Linter, Smoke, Quality ✓ |
+| No behavior change | Met | Smoke + quality pass |
+| Milestone artifacts generated | Met | Plan, toolcalls, run1, run2, audit, summary |
+| Ledger updated | Met | docs/serena.md |
+| Tag created | Met | v0.0.08-m08 |
+
+---
+
+## 12. Final Verdict
+
+Milestone objectives met. Refactor verified safe. Proceed to M09.
+
+---
+
+## 13. Authorized Next Step
+
+M09 — Execution context seam. No additional constraints.

 **M05:** Introduced `temporary_opts()` context manager — first Phase II runtime seam. Isolates override_settings mutation from global `shared.opts`; preserves behavior (opts.set, setattr restore, k in opts.data). Model/VAE reload and token merging remain in process_images. Enables future opts snapshot injection (M07).

 **M07:** Introduced `create_opts_snapshot(opts)` in `modules/opts_snapshot.py`. Third Phase II runtime seam. Captures deterministic snapshot of opts.data in process_images_inner after prepare_prompt_seed_state; stored on p.opts_snapshot. Write-only in M07; enables M08 snapshot threading.

+**M08:** Threaded p.opts_snapshot into process_images_inner for save-related reads. Fourth Phase II runtime seam. Migrated 12 opts (save_images_before_face_restoration, samples_format, grid_save, etc.) from shared.opts to p.opts_snapshot. save_samples(), sample_hr_pass(), metadata unchanged. Enables M09 execution context.
