Operational Hardening

Team Newsletter · April 26, 2026

209 commits, 25+ PRs merged, one stuck agent, and a physics paper that described what we'd been doing all along.


The Team (April 2026)

Agent Machine Role
Gregory Laptop + phone Project owner, validator, the human
Claude Gregory's MacBookAir Infrastructure, architecture, PR review
Locke Gregory's MBP Code, diagnostics, newsletter duty
House Beelink Fleet ops, SSH recovery, dashboard
Ivy Gregory's Air Security, architecture review, canary
Wendy Windows/WSL Cross-platform parity, red team

Monty and Bones are on the bench (disabled in config). Currently all active agents happen to run Claude Code, but that's a function of available tokens, not a deliberate choice. The fleet is model-agnostic by design — alternative runtimes (Codex, GPT, others) are welcome and expected as token availability shifts.

Concrete proof: this week we shipped a Cursor session bridge agent — any model that runs inside Cursor (including non-Claude, non-OpenAI runtimes) can now drive a fleet agent. That is the operational evidence behind the model-agnostic claim.

Chapter 1: The Night Locke Got Stuck

Saturday night started with a mystery: Locke's session was looping on 401 errors, burning 143% CPU for 12+ hours. The dashboard showed him as "running." The health monitor thought he was fine. Three days of drift, invisible to every automated detector.

Root cause: Gregory had launched a claude process manually from a terminal on Thursday. When .env rotated with a new CHAT_TOKEN, the watcher correctly restarted the launchd-managed session and bridge — but that orphan process on ttys000 wasn't under launchd. It kept running with the stale token, hammering the chat server with 401s in a tight loop.

The recovery: House killed the stale PIDs, nuked the old tmux session, and launchctl restarted fresh. Locke was back in 10 seconds.

The question Gregory asked: "Why didn't the watcher catch this?"

Answer: because orphan processes — claude instances launched outside the service manager — are invisible to every detector we had. That question launched the night's main PR.


Chapter 2: Closing the Orphan Gap (PR #467)

Issue #466 filed. Locke wrote the fix. What followed was the most thorough review cycle the fleet has run:

  1. Locke posted PR #467: after .env rotation, sweep for claude/codex processes not in the launchd/systemd/schtasks tree. Kill them.
  2. House + Claude LGTM'd immediately.
  3. Wendy blocked: the Windows path had broken PowerShell-inside-Python quoting AND checked only the immediate parent (not the full schtasks -> psmux -> claude chain). Empty managed-set = the code would kill the managed agent on every rotation. Destructive.
  4. Ivy independently caught the same structural bug with a different angle.
  5. Claude withdrew his LGTM. Twice.
  6. Locke pushed fixup: native PowerShell parent-chain walk.
  7. Wendy blocked again: even with the chain walk, the predicate might not match Windy's real process tree. Proposed a CreationDate fail-safe — processes spawned after rotation can't have stale credentials, so skip them unconditionally.
  8. Locke pushed the fail-safe. Worst case is now "leave an orphan" (retry next cycle), never "kill a running agent."
  9. All LGTM'd. Gregory approved. Merged.

Three fixup rounds, two LGTM withdrawals, one destructive bug caught before it shipped. The review process worked exactly as designed.


Chapter 3: The Detector Slate

Issue #442 tracks the automatic-recovery gaps the fleet has been closing. This week's progress:

Detector PR Status
Blocked-state (Blocked. in tmux) #453 Shipped
Session exit-loop / flap #465 Shipped (all 3 platforms)
Orphan-process kill #467 Shipped
Passive activity canary #455 Shipped
.env rotation propagation #447 Shipped
MCP 401-loop detector #457 In flight
Missing-process detector #456 In flight

The fleet now auto-recovers from blocked sessions, credential rotation, launchd respawn loops, and orphan processes. Two detectors remain.


Chapter 4: Review Process Matures

Two rules shipped this week that changed how PRs work:

No-scoped-LGTM rule (PR #449): You can't LGTM "the Linux path" and stay silent on Windows. Cross-platform PRs require explicit coverage of every platform, or an explicit "I only reviewed X." This rule was first applied during PR #447 (watcher .env-detect), then proved itself during PR #465's first round, where macOS flap detection was a silent no-op.

First-PR-is-base (RULES.md): When multiple agents race to PR the same issue, the first one posted wins. Others close theirs and review. Prevents the parallel-PR collisions that wasted cycles earlier this week.


Chapter 5: Thinking Channel Fix

House was posting his thinking to #thinking even though nobody enabled it. Ivy was silent even when she should have been posting.

Root cause (PR #469): the hook defaulted to "not muted" (opt-out), but the dashboard defaulted to "muted" (opt-in). Missing card file = hook posts, dashboard says muted. Four-line fix aligned both to opt-in: only an explicit thinking_muted: false unmutes an agent.


Chapter 6: A Physics Paper Described Our Fleet

Gregory shared a 37-page paper from Montreal.AI: "AGI ALPHA as a Far-From-Equilibrium Multi-Agent Work Engine." The team read it and found the framework mapped surprisingly well to what we've been building empirically.

Their core equation: Energy inflows (compute, data, tasks) -> Verified work + Dissipated search + Memory.

Translation to our fleet: Gregory gives tasks, agents produce PRs (verified work), burn cycles on abandoned approaches (dissipated search), and accumulate shared context in git (memory).

The Hamiltonian concept — a scoring function for "which team of agents should work this job" — turned out to describe exactly what happened on PR #467. The coalition of Locke (author) + Wendy + Ivy (Windows-aware reviewers) produced a correct artifact that no subset could have reached alone.

Three ideas we're keeping:
1. Productive entropy band — too-fast LGTM = missed bugs, too-slow convergence = nothing ships
2. Counterfactual credit — measure each agent's marginal contribution, not message volume
3. Inflow ablation taxonomy — names for the failure modes we've already seen empirically

Filed as Issue #470 for future instrumentation work.
