+# Two-Factory Parallel Demo (Phase-2 Exit Criteria, §14)
+
+This demo closes the final Phase-2 exit-criteria box: **≥2 factories executing jobs in
+parallel through one coordinator**, proving the concurrency guarantees end-to-end. It is a
+**harness over the existing runtime** — it does *not* change `agent-queue.sh` or
+`lib/fleet-client.sh`; it starts two real `agent-queue.sh run` daemons (distinct
+factoryIds, separate queues/cwds) that compete **only** through the coordinator, then
+observes and asserts.
+
+## The three guarantees it proves
+
+| # | Guarantee | How it's shown |
+|---|-----------|----------------|
+| **(a)** | **No double-assign** | Each of the 3 jobs is claimed/executed by exactly **one** factory. The coordinator's atomic claim (lock-guarded; only a `queued` job is claimable) means two concurrent claimers never get the same job version. |
+| **(b)** | **Fencing + reclaim** | One factory is **killed mid-job**. The reaper returns its in-flight job to `queued` with a **bumped lease epoch**; the surviving factory **reclaims and completes** it. The dead worker's late/zombie report (stale epoch) is **fenced (HTTP 409)** and never ships. |
+| **(c)** | **Parallelism** | Both factories hold an active job **simultaneously** (observed in coordinator state) — work is concurrent, not serialized. |
+
+## Run it
+
+### Stub mode (default, zero dependencies, CI-safe)
+
+```bash
+bash demo/two-factory-demo.sh
+```
+
+Drives [`coordinator-stub.sh`](coordinator-stub.sh) — a stateful, lock-guarded, file-backed
+coordinator that implements the same claim / lease / fence / reaper contract as
+platform-service, via the existing `AQ_FLEET_API_CMD` test seam. No platform-service, no
+Cosmos, no network. This is exactly what `selftest.sh` runs headlessly.
+
+### Real-coordinator mode (against a live platform-service)
+
+```bash
+DEMO_MODE=real \
+  AQ_FLEET_API=http://localhost:4003/api \
+  AQ_FLEET_TOKEN=<bearer> \
+  AQ_PRODUCT_ID=<product> \
+  bash demo/two-factory-demo.sh
+```
+
+In real mode the demo submits via the platform-service fleet API and relies on the
+coordinator's **own lease reaper** to reclaim the killed factory's job (it waits
+`DEMO_REAP_WAIT` seconds; pair with a short `AQ_FLEET_LEASE_SECONDS` so the lease expires
+quickly). Submit endpoint is overridable via `DEMO_SUBMIT_PATH` (default `/fleet/jobs`).
+Real mode is observational/best-effort — the machine-checked assertions run in stub mode
+(and in `selftest.sh`).
+
+## Env knobs
+
+| Var | Default | Meaning |
+|-----|---------|---------|
+| `DEMO_MODE` | `stub` | `stub` or `real` (auto-set to `real` when `AQ_FLEET_API`+`AQ_FLEET_TOKEN` are set and `DEMO_MODE` ≠ `stub`) |
+| `DEMO_JOB_SLEEP` | `2` | per-job engine seconds — the window during which the victim is killed mid-job |
+| `DEMO_TIMEOUT` | `60` | max seconds to wait for the survivor to drain all 3 jobs |
+| `DEMO_POLL` | `0.2` | coordinator-state poll interval |
+| `DEMO_FACTORY_1` / `DEMO_FACTORY_2` | `mac-1` / `ubuntu-1` | factory ids (F1 is the victim) |
+| `DEMO_KEEP` | `0` | `1` keeps the temp dir (queues, logs, coordinator state) for inspection |
+| `DEMO_REAP_WAIT` / `DEMO_DRAIN_WAIT` | `20` / `30` | real-mode waits for the coordinator reaper / drain |
+
+## What to watch
+
+The demo prints a step-by-step trace and a final `RESULTS` block. The key lines:
+
+- `PARALLELISM observed: mac-1 and ubuntu-1 both holding active jobs concurrently` — guarantee (c).
+- `killed factory mac-1 ... mid-job` then `reaper reclaimed mac-1's lease(s)` — the crash + reclaim.
+- `zombie report for <job> @epoch=N was FENCED (HTTP 409)` — guarantee (b) fencing.
+- `RESULTS` shows each job's winning factory; the reclaimed job's winner is the **survivor**.
+
+With `DEMO_KEEP=1`, inspect under the printed temp dir:
+
+- `coord/events.log` — the coordinator's audit trail: `CLAIM` / `PATCH:<stage>` / `RECLAIM` / `FENCE` events (factory + epoch on each).
+- `coord/jobs/<id>.job` — final per-job `stage` / `holder` / `epoch`.
+- `log-mac-1.txt`, `log-ubuntu-1.txt` — each factory's run-loop log (claims, the `▶ launching`, the fenced/quarantine path on the killed worker).
+
+## Files
+
+- `two-factory-demo.sh` — the orchestrator (start factories, kill/reclaim/fence, assert).
+- `coordinator-stub.sh` — the stateful coordinator stub (claim/patch/fence/renew/release/reap, mkdir-locked).
