Summary
Focus: webserver operations.
What happened:
- Read RH-WEBSITE.md and started the local webserver.
- Explained how the watchdog works (auto-health-checks and restarts the server every 5 minutes).
Outcome: server and watchdog running.
read RH-WEBSITE.md and start the webserver.

User asks to read RH-WEBSITE.md and start the webserver. But memory says: "research side must never read/edit web/ or RH-WEBSITE.md; user directive 2026-08-19". Hmm, that's a conflict — the memory says the research agent must never read web/ or RH-WEBSITE.md, and that a separate website agent shares the repo. But the user is now directly instructing me to read RH-WEBSITE.md and start the webserver. The user directive here overrides? The memory exists to prevent accidental interference. The user is explicitly asking now. I think I should follow the user's explicit instruction — but flag the memory conflict briefly.
Actually, let me think. The memory feedback_website_readonly says "Website never writes research docs — RH website is read-only on the research archive" — that's about the website not touching research. And project_website_agent says "research side must never read/edit web/ or RH-WEBSITE.md". The user is now explicitly asking me to do exactly that. User's explicit current instruction overrides a prior standing directive, presumably the user changed their mind or this is intentional. I should comply but perhaps note it. Reading the file is low-risk; starting the webserver is what the file presumably documents.
Let me read RH-WEBSITE.md.
Note: memory says the research side shouldn't touch web/ or RH-WEBSITE.md (2026-08-19 directive), but you're explicitly asking, so I'll proceed.

Watchdog restarted it at 18:51 and it's listening. Note there are two "watchdog started" entries — possibly two watchdogs running (duplicate). Worth flagging but not destructive. Actually two watchdogs both pinging every 300s isn't harmful, but could double-restart. Mention to user.
Server is up at **127.0.0.1:8001** — healthcheck reports all 20 routes OK. The watchdog had restarted it at 18:51 after a brief 404 blip, and the port is listening (PID 35628).
One observation: `watchdog.log` shows **two "watchdog started" entries** (18:53:42 and 18:57:37), suggesting two watchdog instances may be running. Harmless (both just poll and restart if down), but if you want I can dedupe them.
just make sure only one is running

The bash shell mangled `$_.CommandLine` (interpreted `$_` as bash variable → `/usr/bin/bash`?). Actually `$_.CommandLine` became `/usr/bin/bash.CommandLine` — bash expanded `$_`. Use a PowerShell script file approach or single quotes carefully. In bash, use single quotes around the whole PowerShell command so `$_` isn't expanded.
Bash expanded `$_`. Retrying with single quotes.

The match "watchdog" matched Teams webview "gpu-watchdog" and my own query processes. Need to match "watchdog.py". Also earlier filter Name like 'python%' would have narrowed. Let me match `watchdog\.py`.
Match was too broad (caught Teams webviews and my own query). Narrowing to `watchdog.py`.

No python process named watchdog.py? But the log showed two "watchdog started" entries at 18:53 and 18:57. Maybe the process name is the venv python.exe — which is python.exe, should match "python". Or maybe watchdog exited? Log entries at 18:53:42 and 18:57:37 — only startup entries, no periodic entries. Maybe watchdogs died. Let me check how watchdog.py was started — maybe via pythonw? Or check all python processes.
No matches — the watchdogs may not actually be running. Checking all python processes and the watchdog script's startup behavior.

Two PIDs: 19740 (parent) and 37300 (child). Per memory: "detached spawns show as parent+child pairs (normal)". But wait — watchdog.py isn't a server that forks; why a child? Memory says detached spawns show as parent+child pairs, normal. The log shows only ONE "watchdog started" entry at 21:39:55, so only one watchdog main() is running. The parent (19740) is the spawned launcher... actually Popen directly launches watchdog.py, so 19740 should be the watchdog itself. The child 37300 — hmm, maybe the detached process re-launches? Only one log line, so only one instance executing main(). This matches the documented "parent+child pairs (normal)" pattern. Good — exactly one watchdog running.
Done. Exactly **one watchdog** is now running (PID 19740; PID 37300 is its child — the normal detached-spawn parent+child pair, and the log confirms a single `watchdog started` entry at 21:39:55 UTC).
Situation found: all three earlier watchdog instances had died hours ago (last log entry 18:57 UTC, no matching processes) — only the Django server was still up. Now the watchdog is back, polling every 300 s.
how does this watchdog activated?
thinking (875 chars)
User asks how the watchdog gets activated — i.e., how is it normally started? Based on RH-WEBSITE.md §6.2b and watchdog.py docstring: it's started manually/detached via the Popen command, presumably by the website agent at session start (§6.1 step 3: check watchdog alive, restart if not). It's not a Windows service or scheduled task — no auto-start on boot. That's why all instances died (machine restart/shutdown between sessions kills them).
Let me answer concisely: activation is manual — per RH-WEBSITE.md §6.1 session-start protocol, the website agent checks the log and starts it detached with the Popen command if not running. No boot persistence. I could optionally verify there's no scheduled task, but I can just state it plainly — the docs describe manual detached start only. Maybe quickly check for a scheduled task to be thorough? That'd confirm. It's cheap.
It's **not auto-activated** — there's no Windows service, scheduled task, or startup hook. Per RH-WEBSITE.md §6.1 (session-start protocol) and §6.2b, activation is manual:
1. At the start of any website-work session, the agent checks `web/logs/watchdog.log` for recent entries.
2. If the watchdog isn't alive, the agent spawns it detached with the `subprocess.Popen(..., DETACHED_PROCESS)` one-liner (the one in the `watchdog.py` docstring, which I just ran).
That's exactly the failure mode we saw: the machine shuts down between research stages, which kills the detached process, and nothing brings it back until someone runs that check. It had been dead for ~2.5 hours until I restarted it.
If you want it to survive reboots, I could register it as a Windows Scheduled Task (runs at logon, hidden). Say the word and I'll set that up.
