+# M09 Audit — Execution Context Introduction
+
+**Milestone:** M09  
+**Title:** Execution context introduction  
+**Mode:** DELTA AUDIT  
+**Range:** 710a0abd (M08) → 2c6a2510 (M09 merge)  
+**CI Status:** Green (Quality 22986731960)  
+**Refactor Posture:** Behavior-Preserving  
+**Audit Verdict:** 🟢 Milestone objectives met. Runtime context introduced. Phase II complete. Proceed to M10.
+
+---
+
+## 1. Executive Summary (Delta-First)
+
+**Wins:**
+* Introduced RuntimeContext dataclass grouping model, opts_snapshot, device, state, cmd_opts
+* Attached p.runtime_context in process_images_inner() after opts_snapshot creation
+* Additive only; no migration of shared.* reads; no behavior change
+* Fifth Phase II runtime seam; completes Phase II — Runtime Seam Preparation
+* New module runtime_context.py 100% covered by quality tests
+
+**Risks:** None identified.
+
+**Next action:** Proceed to M10 (ProcessingRunner skeleton).
+
+---
+
+## 2. Delta Map & Blast Radius
+
+| Changed | Impact |
+|---------|--------|
+| modules/runtime_context.py | New — RuntimeContext dataclass |
+| modules/processing.py | Modified — import + p.runtime_context assignment |
+| docs/milestones/M09/* | Plan, toolcalls, run1, run2, audit, summary |
+
+**Consumer surfaces touched:** None. API, CLI, file formats, extension API unchanged.
+
+**Blast radius:** process_images_inner initialization only. Context is write-only; no reads migrated. Breakage would require RuntimeContext construction failure — covered by smoke/quality tests exercising full generation path.
+
+---
+
+## 3. Architecture & Modularity Review
+
+* **Boundary violations:** None. RuntimeContext is a simple data container.
+* **Coupling added:** Minimal — processing imports runtime_context; no new circular deps.
+* **Dead abstractions:** None. Context will be consumed in Phase III.
+* **Layering leaks:** None.
+
+**Keep:** Current structure. **Fix now:** None. **Defer:** None.
+
+---
+
+## 4. CI/CD & Workflow Audit

+
+**CI Root Cause Summary:** N/A (all green).  
+**Minimal Fix Set:** None.  
+**Guardrails:** Unchanged from M08.
+
+---
+
+## 5. Tests, Coverage, and Invariants (Delta-Only)
+
+* **Coverage delta:** runtime_context.py 100% covered; overall 40% maintained.
+* **New tests:** None added; existing smoke/quality tests cover critical path (process_images_inner invoked).
+* **Invariant verification:** PASS — generation behavior, file output, extension compat, API, CLI preserved.
+* **Flaky tests:** None introduced.
+
+**Missing Invariants:** None.  
+**Missing Tests:** None for M09 scope.  
+**Fast Fixes:** None.

+
+* **Dependency deltas:** None. No new dependencies.
+* **Secrets exposure:** None.
+* **Workflow trust boundary:** Unchanged.
+* **pip-audit:** Informational; vulns deferred to M27 (M04 baseline).

+
+---
+
+## 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.

+# M09 Summary — Execution Context Introduction
+
+📌 Milestone Summary — M09: Execution Context Introduction
+==========================================================
+
+**Project:** Serena  
+**Phase:** Phase II — Runtime Seam Preparation  
+**Milestone:** M09 — Execution context introduction  
+**Timeframe:** 2026-03-11 → 2026-03-12  
+**Status:** Closed  
+**Baseline:** 710a0abd (M08 merge)  
+**Refactor Posture:** Behavior-Preserving
+
+---
+
+## 1. Milestone Objective
+
+M09 existed to introduce a lightweight runtime execution context that groups model, opts_snapshot, device, state, and cmd_opts. The context is attached to the processing object as `p.runtime_context` but is write-only in M09 — no migration of `shared.*` reads yet.
+
+**What would remain unsafe or ungoverned if this refactor did not occur?** The runtime would lack a single object grouping its dependencies, blocking Phase III ProcessingRunner and testable runtime extraction. Extensions would remain coupled to global shared state with no seam for future isolation.
+
+---
+
+## 2. Scope Definition
+
+### In Scope
+
+* `modules/runtime_context.py` — New RuntimeContext dataclass (model, opts_snapshot, device, state, cmd_opts)
+* `modules/processing.py` — Attach p.runtime_context in process_images_inner() after opts_snapshot creation
+* CI: Linter, Smoke Tests (PR), Quality Tests (post-merge)
+* Documentation: M09_plan.md, M09_toolcalls.md, M09_run1.md, M09_run2.md
+
+### Out of Scope
+
+* Migration of shared.sd_model, shared.device, shared.state, shared.cmd_opts reads
+* Extension interface changes
+* Sampling behavior changes
+* API/CLI changes
+
+---
+
+## 3. Refactor Classification
+
+### Change Type
+
+**Mechanical refactor** — Add new dataclass and assign it to p.runtime_context. No logic change; additive only.
+
+### Observability
+
+* **API responses:** Unchanged
+* **CLI output:** Unchanged
+* **File formats / save paths:** Unchanged
+* **Model outputs:** Unchanged
+
+---
+
+## 4. Work Executed
+
+* Created modules/runtime_context.py with RuntimeContext dataclass
+* Added import and assignment in process_images_inner() after p.opts_snapshot
+* No functional logic changed; context populated from shared.* but not consumed
+* Files changed: modules/runtime_context.py (new), modules/processing.py, docs/milestones/M09/*
+
+---
+
+## 5. Invariants & Compatibility
+
+### Declared Invariants (must by default Not Change)
+
+* Generation behavior unchanged (same inputs → same outputs)
+* File output behavior unchanged
+* Extension compatibility (shared.* unchanged)
+* 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 #26 |
+| Smoke Tests | pytest test/smoke | ✓ | PR #26, run 22984770373 |

+| Coverage | ≥40% gate | ✓ | 40% combined; runtime_context.py 100% |
+| 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
+
+---
+
+## 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 execution context: fifth Phase II seam
+* Phase II — Runtime Seam Preparation complete
+* Invariants preserved and verified by CI
+
+**What is now provably true that was not provably true before?** The generation runtime exposes `p.runtime_context` grouping model, opts_snapshot, device, state, cmd_opts. This completes Phase II and enables Phase III ProcessingRunner and shared state reduction.
+
+---
+
+## 11. Exit Criteria Evaluation
+
+| Criterion | Status | Evidence |
+|-----------|--------|----------|
+| RuntimeContext introduced | Met | modules/runtime_context.py |
+| Context attached to processing object | Met | p.runtime_context in process_images_inner |
+| 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 | v0.0.09-m09 |
+
+---
+
+## 12. Final Verdict
+
+Milestone objectives met. Refactor verified safe. Phase II complete. Proceed to Phase III (M10).
