+# Multi-Coordinator Stress Test — Run 005
+
+**Generated:** 2026-04-30T13:25:15.497712275Z
+**Coordinators:** alice / bob / carol (each with own playbook namespace: `playbook_alice` / `playbook_bob` / `playbook_carol`)
+**Contracts:** alpha_milwaukee_distribution / beta_indianapolis_manufacturing / gamma_chicago_construction
+**Corpora:** `workers,ethereal_workers`
+**K per query:** 8
+**Total events captured:** 61
+**Evidence:** `reports/reality-tests/multi_coord_stress_005.json`
+
+---
+
+## Diversity — is the system locking into scenarios or cycling?
+
+| Metric | Mean Jaccard | n pairs | Interpretation |
+|---|---:|---:|---|
+| Same role across different contracts | 0 | 9 | Lower = more diverse (different region/cert mix → different workers) |
+| Different roles within same contract | 0.03610093610093609 | 18 | Should be near-zero (different roles = different worker pools) |
+
+**Healthy ranges:**
+- Same role across contracts: < 0.30 means the system is genuinely picking different workers per region/contract.
+- Different roles same contract: < 0.10 means role-specific retrieval is working.
+- If either is > 0.50, the system is "cycling" the same handful of workers regardless of query intent.
+
+---
+
+## Determinism — same query reissued, top-K stability
+
+| Metric | Value |
+|---|---:|
+| Mean Jaccard on retrieval-only reissue | 1 |
+| Number of reissue pairs | 12 |
+
+**Interpretation:**
+- ≥ 0.95: HNSW retrieval is highly deterministic; reissues land on near-identical top-K. Good — system locks into a stable view of "best workers for this query."
+- 0.80 – 0.95: Some HNSW or embed variance, acceptable.
+- < 0.80: Retrieval is unstable — reissues see substantially different results, suggesting either embed nondeterminism (Ollama returning slightly different vectors) or vectord nondeterminism (HNSW insertion order affecting recall).
+
+---
+
+## Learning — handover hit rate
+
+Bob takes Alice's contract using Alice's playbook namespace. Did Alice's recorded answers surface in Bob's results?
+
+| Metric | Value |
+|---|---:|
+| Verbatim handover queries run | 4 |
+| Alice's recorded answer at Bob's top-1 (verbatim) | 4 |
+| Alice's recorded answer in Bob's top-K (verbatim) | 4 |
+| **Verbatim handover hit rate (top-1)** | **1** |
+| Paraphrase handover queries run | 4 |
+| Alice's recorded answer at Bob's top-1 (paraphrase) | 4 |
+| Alice's recorded answer in Bob's top-K (paraphrase) | 4 |
+| **Paraphrase handover hit rate (top-1)** | **1** |
+
+**Interpretation:**
+- Verbatim hit rate ≈ 1.0: trivial case — Bob runs identical queries; should always hit.
+- Paraphrase hit rate ≥ 0.5: institutional memory survives wording change — the harder learning property.
+- Paraphrase hit rate ≈ 0.0: Bob's paraphrases drift past the inject threshold, so Alice's recordings don't activate. Same caveat as the playbook_lift paraphrase pass.
+
+---
+
+## Per-event capture
+
+All matrix.search responses live in the JSON — top-K with worker IDs, distances, and per-corpus counts. Search by phase:
+
+```bash
+jq '.events[] | select(.phase == "merge")' reports/reality-tests/multi_coord_stress_005.json
+jq '.events[] | select(.coordinator == "alice" and .phase == "baseline")' reports/reality-tests/multi_coord_stress_005.json
+jq '.events[] | select(.role == "warehouse worker") | {phase, contract, top_k_ids: [.top_k[].id]}' reports/reality-tests/multi_coord_stress_005.json
+```
+
+---
+
+## What's NOT in this run (Phase 1 deliberately defers)
+
+- **48-hour clock.** Events fire as discrete steps, not on a timeline.
+- **Email / SMS ingest.** No endpoints exist on the Go side yet.
+- **New-resume injection mid-run.** The corpus is fixed at the start.
+- **Langfuse traces.** Need Go-side wiring.
+
+These are Phase 2/3. The Phase 1 substrate is what the time-based runner will mount on top of.
