+# M01 CI Run 2 — Analysis
+
+**Date:** 2025-03-07  
+**Branch:** m01-ci-truthfulness  
+**Trigger:** Skip prepare-environment (31588a1e)
+
+---
+
+## 1. Workflow Identity
+
+| Workflow | Run ID | Status |
+|----------|--------|--------|
+| Linter | 22809961294 | ✓ success |
+| Tests | 22809961290 | ✗ failure |
+
+---
+
+## 2. Result
+
+**Setup environment** and **Smoke startup** passed (--exit handling works).
+
+**Start test server** step completed (process launched in background).
+
+**Run tests** failed: wait-for-it timed out (server never bound to 7860).
+
+---
+
+## 3. Root Cause
+
+From output.txt artifact:
+
+```
+ModuleNotFoundError: No module named 'torch'
+```
+
+With `--skip-prepare-environment`, we never run `prepare_environment()`, so torch/clip/requirements were never installed.
+
+---
+
+## 4. Fix Applied
+
+Added **Install runtime dependencies** step (commit 69637193):
+
+- pip install torch, torchvision (CPU)
+- pip install CLIP (--no-build-isolation)
+- pip install open_clip
+- pip install -r requirements_versions.txt
+
+---
+
+## 5. Remaining Blocker
+
+`paths.py` asserts `sd_path` exists (repositories/stable-diffusion-stability-ai). The app requires the `repositories/` folder. With `--skip-prepare-environment`, we never clone. Repositories must come from **cache**. Cache key `repos-2023-12-30` has never been populated (clone has not succeeded).
+
+**Options to seed cache:**
+- workflow_dispatch job with PAT for cross-org clone
+- One-time local bootstrap + cache upload (if supported)
+- Add repositories as submodules
+
+---
+
+## 6. Run 3 (69637193): Confirmed
+
+**Error:** `AssertionError: Couldn't find Stable Diffusion in any of: [repositories/stable-diffusion-stability-ai, ...]`
+
+Torch/clip/requirements now install correctly. The app requires `repositories/` (paths.py). Cache `repos-2023-12-30` is empty. Must be seeded for CI to pass.
