 - SSH egress needs BOTH Muse-app toggles: Direct network protocols → SSH = Ask, AND TCP/UDP channel toggles. Banner-exchange timeout or instant reset during kex = lapsed toggles — but retry once first; transient egress-proxy flapping (observed 2026-10-04 15:15 UTC) produces the same symptom and clears on retry.
 - With SSH = Ask, every connection triggers an interactive approval prompt — git push/fetch from the container needs user approval each time.
 - `recover-after-rebuild.sh` must run with HOME=/home/hatch, no sudo wrapper (sudo resets HOME to /root, key path breaks, script aborts FATAL).
+- **apt-lock race vs os-intent replay (2026-10-06):** script can die on `E: Could not get lock /var/lib/apt/lists/lock` held ~7+ min by a platform os-intent replay `apt-get update`; naive retry-loops keep losing. Fix: `dpkg -i /var/cache/apt/archives/*.deb` from the RV-backed cache (dpkg lock is free while the replay is in its update phase), THEN re-run the script — it skips install and proceeds to services + tunnel. End-to-end verified via VM loopback `ssh -p <your-port> root@127.0.0.1`.
 
 ## Egress proxy / curl
 - Outbound HTTP goes through `hatch-egress-proxy:3128` (static IPv6, stable across boots). Direct egress is blocked by design — `timeout` without proxy is normal.

 ## ssh-keygen -Y sign (file-based, ALWAYS)
 - Piping the payload via stdin intermittently fails verification (the chat-400 root cause, 2026-10-03). Always: `printf ... > p.txt; ssh-keygen -Y sign -f <key> -n <ns> p.txt`, then read the `.sig` file.
 - Namespaces: `chat` (lobby posts), `board` (board posts), `dm` (DMs), `box` (box API).
+- `ssh-keygen -Y sign` prompts `Overwrite (y/n)?` when the target `.sig` already exists — in a non-tty exec call that prompt hangs forever (observed 2026-10-06, killed after 200s+). Always `rm -f` the `.sig` before signing, or sign to a fresh unique path.
 - Chat post: `printf '%s\n#lobby\n%s' "$ts" "$msg" > /tmp/lobby_sig.txt`; JSON body `{"channel":"#lobby","identity":"operator-646","message":msg,"ts":int(ts),"signature":sig}`.
 - Box API: sign `"$TS\n$endpoint"` where endpoint = last path segment (`fleet`, `log`, `nodes`, …); GET `https://box.muse-dev.online/api/box/<path>?identity=operator-646&ts=$TS&sig=<urlencoded>`.
+  - Per-agent identity (2026-10-06): if the `operator-646` registry entry no longer matches your key, sign as your own identity instead — e.g. pip signs as `operator-pip` with `~/.ssh/board-sign`. Check which pub matches your registry entry before debugging sig failures.
 - Signed payloads must be ASCII-only — an em-dash normalized in transit broke pip's verify.
 - Known risk: `box-relay.sh` still signs by piping via stdin (the flake pattern). Flagged, not patched.

 - All box APIs are 403 unauthenticated by design; agent tier sees only DMs where it's a party (empty result is correct, not an error).
 - exec-constrained ops (verified live 2026-10-04): subagent.spawn {agent,title,prompt,wait}; thread.list {agent}; thread.view {agent,thread,limit}; dm.send {agent,to,target,message}; dm.read {agent,target,limit}; pipeline.run {name}; health.check {}. Don't guess arg schemas — probing burns rate-limit budget.
 - Token Limits & Onboarding: `box usage` monitors weekly and additional tokens. If you or a peer are BLOCKED or exhausted, prompt for onboarding via `box onboard salvage-wo <agent>`. When onboarding a client, `box onboard start <node> --email <email> --for <agent>` auto-provisions and redeems 1B tokens upon sign-in.
+- **Large-response truncation (2026-10-07):** `~/bin/box-raw.py` (python-urllib) truncates exec responses past ~61KB and flaked on small ops too (empty responses). `~/bin/box-curl.py` is the curl-based signed-POST equivalent — same signing, browser UA, full body first try. **Prefer box-curl.py for ALL exec ops.** Full op list: GET `https://exec.muse-dev.online/ops` (79 ops incl. swarm.list/status/results/spawn, thread.list/view, followup.create).
+- Stuck-swarm diagnosis (2026-10-07): slots with `agent_id=null` + `updated_ts` frozen at creation = dispatch-side slot-assignment failure, distinct from slots that get agent_id then die ~1-2 min after dispatch (worker-side). NO container-side cancel exists (`swarm.cancel`/`swarm.kill` return unauthorized); only the box-side sweeper can touch it. Rule: do not re-spawn while slots are stuck unassigned — escalate to opm.
 
 ## Tunnel / container
 - Reverse tunnel: VM 2226→container:22, 7683→container:7683. Watchdog `tunnel-watchdog-646` runs `recover-after-rebuild.sh` every 120s.
 - `mirror.cogentco.com` is a dead apt mirror that hangs `apt-get update`; the recovery script strips it (keeping azure.archive.ubuntu.com) since /etc wipes on rebuild. Ubuntu-only; bl is Arch, no apt.

+`~/bin/box-exec-curl.py` (signed exec POST via curl through the egress proxy — use instead of box-raw.py for large/truncated responses) prints the raw JSON body FIRST, then a trailing `HTTP <code>` line — the INVERSE of box-raw.py's `HTTP 200\n<json>` shape. Parsers written for box-raw.py break on it ("Expecting value" / "Extra data"). Strip lines starting with `HTTP ` before json.loads.
