4. Step 2 — Refactor Signal Integrity

A) Tests

• Tier: Smoke only (test/smoke)
• Coverage of refactor target: Smoke tests exercise txt2img and img2img API endpoints, which call process_images() → process_images_inner(). The new p.runtime_context is attached immediately after p.opts_snapshot; the generation path is unchanged. Smoke tests verify generation and save behavior.
• Failures: None
• Golden/snapshot: Smoke tests use CI fake inference (deterministic 1×1 PNG); no golden image comparison. API contract (response schema) and save paths exercised.
• Missing: Quality tier tests will run on push to main (coverage ≥40%, pip-audit, verify_pinned_deps).

B) Coverage

• Smoke run does not enforce a coverage gate (Quality Tests do, on push to main).
• Coverage gate: ≥40% (M04 baseline).
• Post-merge Quality run will report coverage.

C) Static Gates

• Ruff and eslint passed. No new lint issues introduced by M09 changes.
• New module runtime_context.py passes ruff.

5. Step 3 — Delta Analysis

Change Inventory

File	Change
modules/runtime_context.py	New: RuntimeContext dataclass (model, opts_snapshot, device, state, cmd_opts)
modules/processing.py	Import RuntimeContext; attach p.runtime_context in process_images_inner() after opts_snapshot
docs/milestones/M09/M09_plan.md	Populated full plan
docs/milestones/M09/M09_toolcalls.md	Tool call log

Unchanged (per M09 rules): All shared.sd_model, shared.device, shared.state, shared.cmd_opts reads remain. Context is write-only; no migration yet.

Expected vs Observed

• Expected: Same inputs → same outputs; no behavior change; p.runtime_context populated but not consumed.
• Observed: All smoke tests pass. No regressions.

---

6. Step 4 — Invariant Verification

Invariant	Verification	Status
Generation behavior unchanged	Smoke tests pass; context is additive only	✓
File output behavior	Save paths and format unchanged	✓
Extension compatibility	shared.* unchanged; extensions unaffected	✓
API responses	txt2img/img2img smoke tests pass	✓
CLI behavior	No CLI changes	✓

---

7. Blast Radius

Files changed:

• modules/runtime_context.py (new)
• modules/processing.py (modified)
• docs/milestones/M09/*

No other modules changed. Invariant registry surfaces (CLI, API, file formats, extension API, generation semantics) preserved.

---

8. Verdict

CI Status: Green (Linter ✓, Smoke Tests ✓)

Refactor posture: Behavior-preserving. Fifth Phase II runtime seam: generation pipeline now exposes p.runtime_context grouping model, opts_snapshot, device, state, cmd_opts. Write-only; no consumption yet.

Next step: Await merge permission. Post-merge Quality Tests will run (coverage, pip-audit, verify_pinned_deps). M09 run analysis complete; ready for M09 audit and summary generation after closeout.
