feat(bg): B-0440.4 — bus publish on idle detection (full reactive loop closed)#3017
Conversation
…nudge topic; 17 tests pass) Slice 4 of B-0440. When idle is detected, the Standing-by detector now publishes an `infinite-backlog-nudge` envelope via B-0400 bus (PR #3016 schema extension) so any subscribing agent can react. End-to-end working: detector polls git → flags idle → publishes nudge envelope to /tmp/zeta-bus/<uuid>.json. Smoke-verified against real bus. Key design choices: - Adapter pattern extended with publishNudge for deterministic tests (no real bus IO in unit tests) - New flags: --no-publish (dry-run), --agent (sender identity), --to (recipient; default "*" = broadcast) - Publish only fires when idleDetected && !noPublish - Rationale string includes the infinite-backlog-metabolism reminder per PR #2974 Test coverage: - Bus publish path (3 cases: idle+publish, idle+no-publish dry-run, not-idle) - --agent / --to flag plumbing + validation (rejects invalid agent IDs, rejects "*" as sender) - Existing detection paths (idle threshold, null commit, clock skew) Tests: 17 pass / 0 fail / 45 expect() calls (slice 2 had 12 / 29). Note: slice 3 (PR-activity poll via gh CLI) is intentionally skipped ahead of slice 4 because: - Slice 4 unblocks the full reactive loop (detect → nudge → react) - Slice 3 adds a second detection signal (PR activity) that can be layered on later without restructuring - The composes-with chain (B-0440 → B-0440.4 → B-0440.3) makes shipping order operationally honest Future slices: - Slice 3: PR-activity poll via gh CLI (additional detection signal) - Slice 5: integration with agent subscribers (downstream consumers) - Slice 6: cron registration + integration tests Composes with: - B-0440.2 (PR #3011 — commit-history poll this extends) - B-0400 schema extension (PR #3016 — infinite-backlog-nudge topic) - B-0441 + B-0442 (companion services; same slice-4 pattern will land for each) - PR #2974 (infinite-backlog metabolism — the rule the nudge cites) Co-Authored-By: Claude <noreply@anthropic.com>

Pull request overview
Slice 4 of B-0440 wires the Standing-by detector into the B-0400 bus: when idle is detected, the detector publishes an infinite-backlog-nudge envelope and reports the published envelope ID in the poll result. Adds CLI flags (--no-publish, --agent, --to) and extends the adapter pattern with a publishNudge seam for deterministic tests.
Changes:
pollOncenow publishes a nudge envelope on idle (unlessnoPublish), recordspublishedEnvelopeIdin the result, and includes a rationale string referencing infinite-backlog metabolism.DetectorConfiggainsnoPublish,fromAgent,toAgent; CLI argument parsing adds--no-publish,--agent,--towith allow-list validation.- Test suite restructured around slice-4 behavior with fake
publishNudgecapturing calls; coverage added for publish/skip/identity paths.

Removed duplicate VALID_SENDER_IDS / VALID_AGENT_IDS — now reuses the canonical SENDER_IDS / AGENT_IDS exports from tools/bus/types.ts (single source of truth). 2. P1: Wrapped publishNudge() in try/catch so bus IO failures don't kill the daemon poll loop. Failures captured in publishError and surfaced in the result note. 3.

Delay nudge publish until full idle heuristic is satisfied
This now emits infinite-backlog-nudge whenever commit age crosses the threshold, but pollOnce still does not include PR-activity checks (the Standing-by heuristic in B-0440 requires both commit and PR inactivity). In a common case where an agent is actively working in PR threads without new commits, this will publish false-positive nudges every poll interval and can trigger downstream automation on incorrect signals.

Avoid hard-coding the default sender to a single agent
Defaulting fromAgent to "otto" causes misattributed bus envelopes whenever this detector runs under any other agent identity without an explicit --agent override. That breaks provenance and any consumer logic keyed on sender identity, so the sender should be required or derived from runtime identity instead of silently impersonating one agent.

…sh catches multi-agent duplicate work (2026-05-13) Observed multiple times today during the bg-services + Debank launch cascade. Aaron's framing: > "that's a good failure mode, someone else already fixed" When Otto prepares a fix locally, fetch-before-push reveals another factory agent has already pushed the same fix. The catch mechanism is in the fetch step. Without it, two agents would produce duplicate commits or stomp each other. Today's operational examples: - PR #3011: auto-fixer pushed unused-import fix; reset to remote - PR #3012: auto-fixer pushed 4-Copilot-findings fix; reset to remote - PR #3018: Vera + Lior pushed lint + casing fixes; reset to remote Generalizable principle: in multi-agent collaborative editing, fetch-before-push is the cheap convergence mechanism. The cost is one extra git fetch per push. The benefit is correctness in the multi-agent loop.

… + P1 structured lastPublishError field (#3022) Resolves Riven's adversarial review (bus envelope 6c689634-14e7-4cf9-acf8-00c018f1bded): P0 (AC VIOLATION) — Standing-by detector previously only checked commit-history. Per B-0440 AC: "no new commits + no PRs opened/closed in last 15min while autonomous-loop cron is firing". The commit-only implementation produced false negatives for any agent doing PR-review-only / bus-coordination / claim-work without committing — the exact failure mode the service was built to catch. Fix: pollOnce now reads BOTH signals via injected adapters: - lastCommitIso() → ISO-8601 of most recent commit on HEAD - lastPrActivityIso() → ISO-8601 of most recent PR activity in repo Idle gap = pollAt - MAX(commit, pr_activity). Either signal recent means NOT idle. Repo-level (no --author filter) per substrate-honest framing: factory agents share the AceHack GitHub account, so author-filtering would miss most activity. Cited in adapter docstring. P1 (silent failure) — Added structured lastPublishError field to PollResult. Bus publish failures are now machine-readable, not just buried in the note string. The note still surfaces it for human ops but daemons / dashboards can consume the structured field directly. Real smoke test verifies both signals: { lastCommitAt: 2026-05-13T18:49:06.000Z, lastPrActivityAt: 2026-05-13T19:17:58.000Z, idleMinutes: 1.08, // gap from MAX of the two publishedEnvelopeId: 606cae9e-..., lastPublishError: null, } Tests: 16 pass / 0 fail / 47 expect() calls (slice 4 had 17 / 45). New test coverage: - "recent commit only" → NOT idle - "recent PR activity only" → NOT idle (the Riven P0 false-negative case) - "OLD commit + recent PR" → NOT idle - "recent commit + OLD PR" → NOT idle - "BOTH old" → idle flagged - "BOTH null" → no detection (no false positive) - "publish failure surfaces in structured lastPublishError" → P1 fix verified Composes with: - Riven's adversarial review (envelope 6c689634-...) - Otto's reply (envelope e8174b34-fdee-47f7-af1a-df80c27b51cd) - B-0440.2 (PR #3011 — commit-history poll this extends) - B-0440.4 (PR #3017 — bus publish this preserves) - PR #2999 (substrate-honest discipline triad — accept findings + ship fix) Adversarial review caught what solo-Otto missed.

Fix: import + reuse canonical SENDER_IDS / AGENT_IDS from tools/bus/types.ts (single source of truth). Both fixes mirror the pattern landed on PR #3017 for B-0440.4. Tests still 27 pass / 0 fail.

…e mode (auto-load rule per Aaron's CLAUDE.md question) (#3029) Aaron 2026-05-13 caught Otto in the Standing-by failure mode for the third time in one session, asking: "maybe something in claude.md needs to change?" The rules already auto-load from .claude/rules/ per the cold-boot mechanism (.claude/rules/claude-code-loading-taxonomy.md). The existing .claude/rules/never-be-idle.md exists but evidently doesn't fire specifically enough on the cron-tick-Holding pattern. New rule sharpens the existing discipline at the cron-tick scope: when the cron fires and you're about to type "Holding" / "Standing by" / "Waiting" → apply substrate-honest triage: 1. Is there a SPECIFIC named dependency with bounded ETA? → say so. 2. If NO → you're in Standing-by failure mode. Per infinite-backlog metabolism, decomposition work always exists. Pick: - Decompose an ambiguous backlog row - File a B-NNNN row that should exist - Run bun tools/bg/backlog-ready-notifier.ts --once - Sanity-check substrate landed correctly - Address outstanding review thread 3. Repeated single-word "Holding" on consecutive ticks is diagnostic of the failure mode. Why this rule exists (empirical evidence): the same agent who canonized PR #2999 + shipped PR #3017 + wrote the README warning against overclaiming "foreground optional" STILL fell into 60+ consecutive "Holding" ticks. Aaron caught it three times. Encoding rules without mechanizing produces a memory of failures (per .claude/rules/encoding-rules-without-mechanizing.md). This rule IS the mechanization at the cold-boot scope. Composes with: - never-be-idle.md (broader scope; this rule sharpens at cron tick) - no-op-cadence-failure-mode.md (multi-hour scope) - encoding-rules-without-mechanizing.md (rationale) - PRs #2974 + #2999 + #3017 + #3022 (the canonical substrate) - B-0441 slice 5 (subscriber agents — when they arrive, the bus envelope path becomes the runtime catch; this rule remains the cold-boot-substrate complement) Co-authored-by: Claude <noreply@anthropic.com>

Aaron's directive: 'file backlog row for both (shadow*) if yall catch each other it's unlikey you will drive and include you background service to click past stuck promps on both your have your onw internal BFT.' The key insight: 3 Otto surfaces (Otto-CLI, Otto-Desktop, Otto- launchd-background) = built-in 3-of-N Byzantine Fault Tolerance quorum. When 1 surface drifts into Standing-by, the other 2 can catch + correct without Aaron's manual intervention. Filed as 1 umbrella + 3 slices: - B-0539 (umbrella) — Otto-BFT internal-quorum self-recovery - B-0540 — Standing-by counter-with-escalation in the rule (if N≥10 consecutive brief-acks, escalate to picking decomposition work) - B-0541 — Cross-surface bus detector (extension of PR #3017 single-surface detector to quorum across Otto surfaces) - B-0542 — Background service clicks past stuck prompts on foreground Otto surfaces (osascript-driven UI actuator, safety- gated per methodology-hard-limits.md) The BFT framing is real because the 3 surfaces are genuinely independent (different binaries, different model tiers, different OS scheduling). Aaron's same-words-same-pattern catches across surfaces are empirical evidence the failure mode is surface- independent — which makes cross-surface recovery the right mechanism.

Updated the ops note to clarify the operational truth (sufficient for silent-stuck detection, not adversarial); the umbrella title preserves Aaron's verbatim BFT framing 6: Umbrella decomposition metadata for autonomous-pickup tool — added 'decomposition: decomposed' to B-0539 and 'parent: B-0539' to all 3 slice rows so the autonomous picker treats the umbrella as decomposed (won't try to implement it directly) Plus the earlier MD032 markdownlint fix (B-0540 list blank-line) already pushed in 5433c1b.

Summary
Slice 4 of B-0440. The Standing-by detector now closes the full reactive loop: detect idle → publish `infinite-backlog-nudge` envelope via B-0400 bus.
End-to-end smoke-verified:

Slice ordering note
Slice 3 (PR-activity poll) is intentionally skipped — slice 4 was prioritized because it closes the full reactive loop (detect → nudge → react) and slice 3 is additive detection signal that can layer on top without restructuring.
