feat(b-0494): circuit breaker viz — slice-2 live bus snapshot by AceHack · Pull Request #3134 · Lucent-Financial-Group/Zeta

AceHack · 2026-05-14T13:18:50Z

Summary

tools/bus/export-cb-snapshot.ts — new Bun script: reads non-expired /tmp/zeta-bus/ envelopes, normalises surface-tagged sender IDs to identity level (otto-cli → otto), derives CLOSED/HALF_OPEN/OPEN state per agent from idle-heartbeat count, writes demo/circuit-breaker-snapshot.json
demo/circuit-breaker-snapshot.json — committed snapshot from 73 live envelopes (Otto + Vera show active work; others healthy / no recent activity)
demo/index.html — renderCircuitBreakerTab() is now async; tries fetch('./circuit-breaker-snapshot.json', {cache:'no-cache'}) first, falls back to buildCbMockData() on error or missing file — no visible regression when snapshot absent
docs/backlog/P1/B-0494-*.md — backlog row filed with pre-start checklist

Acceptance criteria (B-0494)

tools/bus/export-cb-snapshot.ts exists and runs via bun
demo/circuit-breaker-snapshot.json committed (generated from live bus)
renderCircuitBreakerTab() tries snapshot first, falls back to mock
dotnet build -c Release → 0 warnings, 0 errors
bun tsc --noEmit clean

How to refresh the snapshot

bun tools/bus/export-cb-snapshot.ts
# → Wrote 5 entries (73 envelopes) → demo/circuit-breaker-snapshot.json

Run, commit, push. Future slice: automate via CI or a scheduled script.

Decomposition note (slice-3)

Next: wire a live relay that GitHub Pages visitors can hit to get fresh data without a commit cycle. Tracked as future decomposition of B-0494 / B-0401.

Closes B-0494 slice-2. Parent: B-0435, B-0401.

Pull request overview

Slice-2 of the circuit-breaker visualization: replaces the demo's hardcoded mock data with a snapshot derived from live /tmp/zeta-bus/ envelopes, while keeping the mock as a graceful fallback for GitHub Pages visitors when the snapshot is absent or fetch fails.

Changes:

Adds tools/bus/export-cb-snapshot.ts to read non-expired envelopes, normalise surface-tagged senders (e.g., otto-cli → otto), and derive CLOSED/HALF_OPEN/OPEN state per agent.
Commits an initial demo/circuit-breaker-snapshot.json (73 envelopes, all CLOSED).
Converts renderCircuitBreakerTab() to async; tries the snapshot first and falls back to buildCbMockData() on error/empty.

File	Description
tools/bus/export-cb-snapshot.ts	New Bun script that derives CB state from live bus envelopes and writes the snapshot JSON.
demo/circuit-breaker-snapshot.json	Committed snapshot consumed by the demo at load time.
demo/index.html	`renderCircuitBreakerTab()` now async with snapshot-first / mock-fallback flow.
docs/backlog/P1/B-0494-...md	Backlog row documenting slice-2 scope, approach, and pre-start checklist.

Three reviewer findings addressed: 1. Consecutive idle computation was counting all idle heartbeats in the non-expired window (idleHeartbeats.length). An interleaved pattern like idle→working→idle→idle would report 3 "consecutive" failures instead of the correct trailing streak of 2. Fixed by walking `own` (already sorted newest-first) and stopping at the first non-idle envelope. 2. The `consecutiveFailures` output field now reflects the actual trailing streak, consistent with the field name and the UI contract. 3. argv parsing + I/O were running as unconditional top-level side effects. Wrapped in `async function main()` guarded by `if (import.meta.main)` to match the rest of the toolchain and keep the module importable for tests. Co-Authored-By: Claude <noreply@anthropic.com>

… bus dir - `hasWorkSignal` now filters claim envelopes to `action === "claim"` only; a release envelope no longer keeps an agent in CLOSED/"Active work detected" after it relinquishes work. - `readEnvelopes` lets `readdir` throw instead of silently returning []; main() catches and exits non-zero so misconfiguration is visible rather than masquerading as a healthy empty-bus snapshot. - Replaced unsafe `(e.payload as { … })` casts with discriminated-union narrowing (topic already narrows payload type).
