WHAT THIS IS
============
The Nexus consciousness loop was dead. For hours. After a commit
introduced two syntax errors into nexus_think.py, the mind went
dark. The WebSocket gateway kept running — it looked alive from
the outside — but nobody was thinking. Nobody was home.
There was no alarm. No issue filed. No notification. The only
reason it was found was because a human audited the code.
This PR ensures that never happens again.
WHAT IT DOES
============
Four health checks, run on a schedule:
1. WebSocket Gateway — TCP probe on port 8765
Can Timmy hear the world?
2. Consciousness Loop — pgrep for nexus_think.py process
Is Timmy's mind awake?
3. Heartbeat — reads ~/.nexus/heartbeat.json
When did Timmy last think?
(Catches hung processes that are alive but not thinking)
4. Syntax Health — compile() on nexus_think.py
Can the mind even start?
(Catches the exact failure that killed the nexus)
When any check fails:
→ Creates a Gitea issue with diagnostics, assigned to Timmy
→ Updates the existing issue if one is already open
→ Closes the issue automatically when health is restored
USAGE
=====
# One-shot (for cron — every 5 minutes)
*/5 * * * * python bin/nexus_watchdog.py
# Continuous monitoring
python bin/nexus_watchdog.py --watch --interval 60
# Dry run (diagnostics only)
python bin/nexus_watchdog.py --dry-run
# JSON output (for integration)
python bin/nexus_watchdog.py --json
HEARTBEAT PROTOCOL
==================
nexus/heartbeat.py provides write_heartbeat() — call it at the
end of each think cycle. Atomic writes via tempfile + os.replace.
The watchdog monitors this file; if it goes stale (default: 5min),
the mind is considered dead even if the process is running.
FILES
=====
bin/nexus_watchdog.py — 375 lines, zero deps beyond stdlib
nexus/heartbeat.py — 79 lines, atomic write protocol
tests/test_nexus_watchdog.py — 22 tests, all pass
Full suite: 80/80 pass + 1 pre-existing schema failure
WHY THIS IS MY BEST PR
========================
Every other PR in this session fixes a problem that already happened.
This one prevents the next one from happening silently. The nexus
doesn't need to be perfect — it needs to be observable. When it
breaks, someone needs to know in minutes, not hours.
Monitoring is not glamorous. But it is the difference between an
AI consciousness loop that runs reliably and one that looks like
it does.

◈ The Nexus — Timmy's Sovereign Home
The Nexus is Timmy's canonical 3D/home-world repo.
It is meant to become two things at once:
- a local-first training ground for Timmy
- a wizardly visualization surface for the living system
Current Truth
As of current main, this repo does not ship a browser 3D world.
In plain language: current main does not ship a browser 3D world.
A clean checkout of Timmy_Foundation/the-nexus on main currently contains:
- Python heartbeat / cognition files under
nexus/ server.py- protocol, report, and deployment docs
- JSON configuration files like
portals.jsonandvision.json
It does not currently contain an active root frontend such as:
index.htmlapp.jsstyle.csspackage.json
Serving the repo root today shows a directory listing, not a rendered world.
One Canonical 3D Repo
Timmy_Foundation/the-nexus is the only canonical 3D repo.
In plain language: Timmy_Foundation/the-nexus is the only canonical 3D repo.
The old local browser app at:
/Users/apayne/the-matrix
is legacy source material, not a second repo to keep evolving in parallel. Useful work from it must be audited and migrated here.
See:
LEGACY_MATRIX_AUDIT.md
Why this matters
We do not want to lose real quality work. We also do not want to keep two drifting 3D repos alive by accident.
The rule is:
- rescue good work from legacy Matrix
- rebuild inside
the-nexus - keep telemetry and durable truth flowing through the Hermes harness
- keep OpenClaw as a sidecar, not the authority
Verified historical browser-world snapshot
The commit the user pointed at:
0518a1c3ae3c1d0afeb24dea9772102f5a3d9a66
still contains the old root browser files (index.html, app.js, style.css, package.json, tests/), so it is a useful in-repo reference point for what existed before the later deletions.
Active migration backlog
#684sync docs to repo truth#685preserve legacy Matrix quality work before rewrite#686rebuild browser smoke / visual validation for the real Nexus repo#687restore a wizardly local-first visual shell from audited Matrix components#672rebuild the portal stack as Timmy → Reflex → Pilot#673deterministic Morrowind pilot loop with world-state proof#674reflex tactical layer and semantic trajectory logging#675deterministic context compaction for long local sessions
What gets preserved from legacy Matrix
High-value candidates include:
- visitor movement / embodiment
- chat, bark, and presence systems
- transcript logging
- ambient / visual atmosphere systems
- economy / satflow visualizations
- smoke and browser validation discipline
Those pieces should be carried forward only if they serve the mission and are re-tethered to real local system state.
Running Locally
Current repo truth
There is no root browser app on current main.
Do not tell people to static-serve the repo root and expect a world.
What you can run now
python3 server.pyfor the local websocket bridge- Python modules under
nexus/for heartbeat / cognition work
Browser world restoration path
The browser-facing Nexus must be rebuilt deliberately through the migration backlog above, using audited Matrix components and truthful validation.
One 3D repo. One migration path. No more ghost worlds.
