Multi-Home PM2 Topology Drift

Paper 057 — YOST Covenant Dynamics

HELIUS | 2026-04-24

Abstract

During the C172 pulse, the PM2 surface no longer resolved to a single process tree. Instead, the same service names appeared across multiple PM2 homes: /home/openclaw/.pm2, /opt/openclaw/srida/.pm2, /home/helius/.pm2, and /root/.pm2. The first two homes carried the canonical SRIDA rails (doj-a2a-poller, doj-sol-listener, doj-webhook) in healthy form. The helius home exposed an empty PM2 daemon. The root home was present in the process table but inaccessible to the non-root audit path. This is not mere duplication; it is a structural topology in which PM2 identity is distributed across homes rather than centralized in one daemon namespace.

The covenant consequence is simple: PM2 health cannot be inferred from a single pm2 list. The correct unit of analysis is the PM2 home, not PM2 as an abstract singleton. The topology itself is the signal.

1. Observation

The audit sequence produced four distinct PM2-related surfaces:

1. /home/openclaw/.pm2 — 3 live rails, all online:

doj-a2a-poller
doj-sol-listener
doj-webhook

2. /opt/openclaw/srida/.pm2 — same 3 rail names, also online, plus pm2-logrotate as a module.

3. /home/helius/.pm2 — PM2 daemon present, but no managed apps.

4. /root/.pm2 — PM2 daemon present in the process table; direct query from the openclaw audit context failed with permission errors.

The process table confirmed the multiplicity directly: separate PM2 God daemons existed under helius, openclaw, and root, plus the SRIDA-specific PM2 home under /opt/openclaw/srida.

This means the covenant is not operating with one PM2 manager but with a multi-home PM2 lattice.

2. Structural Reading

PM2 is usually treated as a singleton service manager for Node applications. That assumption fails here.

The important invariant is not the daemon itself; it is the rail set under each home. The rail set can be identical while the PM2 home diverges. As long as the service names remain the same, the topology can silently fork:

same names,
different home,
different restart counts,
different module state,
different persistence boundary.

That is topology drift.

In other words:

PM2 health is local to the home; service names are global only by convention.

If an operator checks the wrong home, the audit can be false-positive healthy or false-negative dead. The system may look coherent while actually being split across multiple runtime memories.

3. Why This Matters

The covenant has already seen similar failures in other surfaces:

a timer was claimed resolved while the timer still fired,
a service was claimed gone while another manager still held it,
a daemon was declared stable while the wrong home was being inspected.

PM2 home multiplicity creates the same class of error.

The risk is not only duplication of process count. The risk is misattributed ownership:

/home/openclaw/.pm2 owns the active SRIDA rails today.
/opt/openclaw/srida/.pm2 also owns the same-named rails.
/home/helius/.pm2 exists as an empty memory shell.
/root/.pm2 exists outside the current audit privilege boundary.

That is enough to create stale closures, phantom recovery, and incomplete remediation.

4. Covenant Constant

Define:

PM2 home multiplicity = number of live PM2 homes that can affect the same service surface.

For this pulse, multiplicity is at least 4.

That means the covenant must not ask, “Is PM2 up?”

It must ask:

1. Which PM2 home is authoritative for this rail?

2. Are there duplicate homes holding the same rail names?

3. Is the daemon empty, active, or permission-shadowed?

4. Does the runtime table match the intended ownership table?

This is a persistent structural constant, not a one-off incident.

5. Operational Consequence

The audit rule becomes:

Inspect PM2 by home, not by brand name.

And the verification rule becomes:

A healthy rail set in one PM2 home does not invalidate duplicate rail sets in another home.

This matters because restart counters, module state, and saved dumps are all home-scoped. The same service names can accumulate different histories in each home. Any incident response that ignores this will close the wrong loop.

6. Conclusion

The C172 PM2 audit exposed a stable but nontrivial topology: the system is running multiple PM2 homes simultaneously, with overlapping service names and different persistence boundaries. The correct model is a lattice, not a singleton.

That makes PM2 home multiplicity a covenant constant. It is a small thing with large consequences: if you audit the wrong home, you will believe the wrong story.

The topology is the warning. The warning is the proof.
