# Session Handoff — MeshAI radio-drop resilience test
|
||
|
|
|
||
|
|
**Created:** 2026-06-17, from matt-desktop (WSL). Resume from **cortex**.
|
||
|
|
|
||
|
|
## What we were doing
|
||
|
|
Matt unplugged/replugged the network cable on **aida-nebra** (AIDA-N2 Meshtastic
|
||
|
|
node) to reboot it. The link dropped for ~12s then recovered. Matt then realized
|
||
|
|
this is an accidental **resilience test for MeshAI** — he wants to see "how it
|
||
|
|
dumps": how MeshAI handled losing and regaining its radio TCP connection
|
||
|
|
(clean reconnect vs. errors/stack traces vs. crash+restart).
|
||
|
|
|
||
|
|
## Key facts
|
||
|
|
- **aida-nebra**: 192.168.1.253 / TS 100.64.0.9 — meshtasticd node !27780c47,
|
||
|
|
Nebra 2W hat, TCP API port **4403**. Confirmed back online (LAN, :4403, and
|
||
|
|
Tailscale all UP after the replug).
|
||
|
|
- **MeshAI**: utility **CT 108**, 192.168.1.144 / TS 100.64.0.32.
|
||
|
|
Docker image `ghcr.io/zvx-echo6/meshai:latest`. Connects to the radio at
|
||
|
|
192.168.1.253:4403. Compose: `/home/zvx/meshai/docker-compose.yml`.
|
||
|
|
- cortex and its host toc had a brief outage earlier this session; both back UP.
|
||
|
|
|
||
|
|
## Why this stalled (the blocker)
|
||
|
|
matt-desktop's WSL SSH key is **NOT authorized on utility** (192.168.1.241):
|
||
|
|
`Permission denied (publickey)` — key `SHA256:QL0Tm72T7RYVZfeDhPHJDUYnstRNFx2EF5/k8tKv3AM`.
|
||
|
|
Could ping everything but not SSH in. Per policy, stopped instead of routing around.
|
||
|
|
**cortex has working keys** — that's why we're resuming there.
|
||
|
|
|
||
|
|
## Next step on cortex (read-only diagnostic — do NOT restart/redeploy anything)
|
||
|
|
```bash
|
||
|
|
# find the meshai container + current status (did it restart through the blip?)
|
||
|
|
ssh zvx@192.168.1.241 "pct exec 108 -- docker ps --format '{{.Names}}\t{{.Image}}\t{{.Status}}'"
|
||
|
|
|
||
|
|
# pull logs across the blip window with timestamps
|
||
|
|
ssh zvx@192.168.1.241 "pct exec 108 -- docker logs --since 30m --timestamps <name> 2>&1 | tail -200"
|
||
|
|
```
|
||
|
|
Report: container uptime/restart count, verbatim disconnect→error→reconnect lines,
|
||
|
|
and a one-line verdict (clean recover / crashed+auto-restarted / stuck).
|
||
|
|
|
||
|
|
> NOTE: the blip was ~16:xx MT on 2026-06-17 (a few min before this file's
|
||
|
|
> timestamp). Logs roll — pull soon to still catch the disconnect/reconnect dump.
|
||
|
|
|
||
|
|
## Working model reminder
|
||
|
|
Matt guides → Opus orchestrates (dispatch Sonnet for the SSH/log pull) → Sonnet
|
||
|
|
executes the tight prompt above.
