# 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.

# M09 CI Run 1 — Execution Context Introduction
**Date:** 2026-03-12
**Branch:** m09-execution-context
**PR:** #26
**Trigger:** pull_request (PR to main)
---
## 1. Workflow Identity
| Workflow | Run ID | Trigger | Branch | Commit | Status |
|----------|--------|---------|--------|--------|--------|
| Linter | 22984770390 | pull_request | m09-execution-context | 398e281d | ✓ success |
| Smoke Tests | 22984770373 | pull_request | m09-execution-context | 398e281d | ✓ success |
**Quality Tests:** Not yet run (triggered on push to main; will run post-merge).
---
## 2. Change Context
| Item | Value |
|------|-------|
| Milestone | M09 — Execution Context Introduction |
| Phase | Phase II — Runtime Seam Preparation |
| Posture | Behavior-preserving |
| Refactor target | `modules/runtime_context.py` (new), `modules/processing.py` (attach p.runtime_context) |
| Run type | First CI verification of M09 implementation |
---
## 3. Step 1 — Workflow Inventory
### Linter (22984770390)
| Job | Required? | Purpose | Pass/Fail |
|-----|-----------|---------|-----------|
| ruff | Yes | Python lint | ✓ |
| eslint | Yes | JS lint | ✓ |
**Duration:** ~19s
### Smoke Tests (22984770373)

| Upload main app output | No (always) | Artifact for debugging | ✓ |
**Duration:** 2m59s
---
## 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 |
| Quality Tests | pytest test/smoke test/quality | ✓ | Post-merge 22986731960 |
| 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).
---
## 13. Authorized Next Step
M10 — ProcessingRunner skeleton. 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).
