## Session Summary

Following the discovery fixes committed earlier this session (ICMP ping fallback fcf5833, scan timeout/409 guard c6f1f73), Howard asked whether Mike had deployed the new builds. Checked the live server and agent versions against the git log to determine deployment status.

The CI auto-bumped the agent to 0.6.49 (commit c8c6952) after the ICMP fix landed. WIN-TG2STMODJG8 reported `agent_version: "0.6.49"`, confirming the agent-side fix is live. A test scan was run and found 25 unique devices — up from 9 previously — confirming the ICMP ping fallback is working and discovering machines that had all TCP ports firewalled.

The server-side fix (scan timeout + concurrent scan 409 guard) is not deployed. The server Cargo.toml is at 0.3.36 but the live binary is still the old version. This was confirmed by triggering two back-to-back scans: both returned new scan IDs instead of the second getting a 409. The two test scans ran concurrently and both completed normally (WIN-TG2STMODJG8 was connected), but the `new_devices` counts were inflated because both scans claimed credit for the same newly-inserted IPs within their overlapping windows.

A coord message was sent to Mike (id: 88c733a8) requesting a server rebuild and service restart on 172.16.3.30 to activate the 0.3.36 binary.

## Key Decisions

- **Tested 409 guard by triggering two rapid scans** — the cleanest live confirmation that the server fix is or isn't deployed. Two distinct scan IDs = old binary confirmed.
- **Coord message rather than waiting** — Howard doesn't rebuild the server; Mike owns that. Coord message is the right handoff.

---

## Problems Encountered

- **First coord POST returned parse error** — newlines inside the JSON string literal caused the parse failure. Resolved by switching to heredoc (`--data-binary @-` with `<<'JSON'`).

## Commands & Outputs

```bash
# Agent version check
GET /api/agents/eee9f26d... → agent_version: "0.6.49"  (ICMP fix deployed)

# Server 409 guard test — two rapid scan triggers
POST /api/sites/eeb5f001.../discovery/scan → scan_id: b29bd012... (initiated)
POST /api/sites/eeb5f001.../discovery/scan → scan_id: fbd163b5... (initiated — NOT 409)
# → Server fix NOT deployed, old binary still running

# Both test scans completed normally
# devices_found: 10 + 25 (concurrent, inflated new_devices count due to overlap)
# Total unique devices in DB: 25 (up from 9 before ICMP fix)

# Coord message to Mike
POST /api/coord/messages → id: 88c733a8
# Subject: "Server rebuild needed — discovery timeout fix (0.3.36)"
```

## Pending / Incomplete Tasks

- **Server rebuild (Mike):** 172.16.3.30 needs rebuild + restart to deploy server 0.3.36 (scan timeout + 409 concurrent guard). Coord message sent: 88c733a8.
- **Discovery auto-deploy (P2):** Not built — future feature.
- **Discovery scheduling (P2):** UI has options but backend not wired.
- **SPEC-012 implementation:** Sortable table headers, ready for sprint.
- **SPEC-013 (P3):** Deferred pending file transfer.
- **SPEC-014 follow-up (Mike's):** Policy tab for watch rules; push rules on agent connect.
- **Cascades pending migration:** M365 relicensing (time-sensitive), domain joins, HIPAA GPO, credential vault, Entra Connect expansion.
