+### 2b. Local git watcher script
+**Owner:** Ramis | **Est:** 1.5h | **Depends on:** task 1, task 3 (schema)
+
+A tiny Node.js script each engineer runs once in a terminal on their machine. Writes git signals **directly to MongoDB Atlas** every 15s — no HTTP to Hermes. Hermes reads merged state (vision + git) from Atlas when running event detection.
+
+- [ ] `scripts/podman-agent.mjs` — CLI script, no extra dependencies beyond Node.js + `mongodb` driver
+- [ ] Args: `--name alice --pod demo-pod` (reads `MONGODB_URI` from env or `.env` in repo root)
+- [ ] Every 15s: shell out to `git status --short`, `git diff --stat HEAD`, `git log --oneline -1`, `git branch --show-current`
+- [ ] Upsert into `engineer_states` (same collection as vision pipeline) — update only git fields, leave vision fields untouched:
+  ```ts
+  { $set: { changedFiles, diffStat, recentCommit, branch, gitUpdatedAt } }
+  ```
+- [ ] On startup: log `[podman-agent] alice connected to demo-pod — watching git every 15s`
+- [ ] Graceful exit on Ctrl+C
+
+**Usage:**
+```bash
+node scripts/podman-agent.mjs --name alice --pod demo-pod
+```
+
+**Why MongoDB-direct (not POST /ingest):** git signals and vision signals update at different rates and from different sources. MongoDB is the shared state bus — Hermes reads merged state, not two separate streams.
+
+**Files:** `scripts/podman-agent.mjs` (new)

+Latest context per engineer. Two writers, one collection — vision pipeline upserts vision fields, git watcher script upserts git fields independently. Hermes reads the merged document for event detection.
