+# Mission Cell Directory Spec
+
+This document defines the foundational Mission Cell filesystem contract for Lazarus Pit.
+It is a grounded M6 foundation slice, not the full Mission Cell runtime.
+
+Root layout:
+- `/var/missions/<uuid>/`
+
+Required subdirectories:
+- `meta/`
+- `config/`
+- `state/`
+- `logs/`
+- `artifacts/`
+- `worktree/`
+
+Required seed files:
+- `meta/mission.json`
+- `config/cell.json`
+- `state/heartbeat.json`
+- `logs/daemon.log`
+
+## Intent of each path
+
+- `meta/mission.json`
+  - durable mission identity and lifecycle metadata
+  - includes `mission_id`, `created_at`, and current status
+- `config/cell.json`
+  - local cell wiring
+  - points to the worktree, artifacts directory, and heartbeat file
+- `state/heartbeat.json`
+  - latest cell heartbeat timestamp and state
+  - consumed by Lazarus Pit scans for healthy vs stale cell classification
+- `logs/daemon.log`
+  - daemon-local operational log target
+- `artifacts/`
+  - handoff packets, reports, checkpoints, and mission outputs
+- `worktree/`
+  - mission-specific checked-out repository workspace
+
+## Lazarus Pit daemon skeleton
+
+`scripts/lazarus_pit.py` provides the foundation daemon behavior:
+- initialize a Mission Cell scaffold with `--init-cell <uuid>`
+- scan all cells under the configured missions root
+- classify cells as `healthy`, `stale`, `incomplete`, or `uninitialized`
+- emit a daemon heartbeat through the existing cron heartbeat writer
+- output a JSON health report for higher-level watchers
+
+Default config lives at:
+- `config/lazarus_pit.json`
+
+## Example bootstrap
+
+```bash
+python3 scripts/lazarus_pit.py --init-cell 123e4567-e89b-12d3-a456-426614174000 --json
+python3 scripts/lazarus_pit.py --write-heartbeat --json
+```
+
+## What remains for full #879 completion
+
+This slice does not yet complete the whole issue.
+Still open:
+- health heartbeat endpoint on existing wizard gateways
+- Gitea mission proposal issue template
+- live daemon service wiring / long-running supervisor integration

+- Iteration limits: 5-iteration agents can't push
+- Repository cloning: May hit timeout on slow clones
+
+### Confidence Level
+- High confidence: 800+ commits, 150+ PRs
+- Medium confidence: 1,000+ commits, 200+ PRs
+- Low confidence: 1,200+ commits, 250+ PRs (requires all loops running clean)
