From 119e91317697709ff66431d145247b44930d9198 Mon Sep 17 00:00:00 2001 From: UncleSp1d3r Date: Sat, 18 Apr 2026 19:23:54 -0400 Subject: [PATCH 01/28] =?UTF-8?q?feat(eventbus):=20close=20END-297=20?= =?UTF-8?q?=E2=80=94=20finalize=20message=20broker=20closure=20pass?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes END-297 by addressing the four remaining gaps that prevented formal sign-off of the multi-collector message broker: Unit 1 — Control-message subscription delivery (the only real functional gap). EventBusClient gains an opt-in `include_control: bool` field on EventSubscription (default false for backward compatibility) and a new `subscribe_with_control()` method returning parallel (event_rx, control_rx) receivers. procmond replaces its start-monitoring-immediately workaround with subscribe-then-wait on control.collector.lifecycle, honoring BeginMonitoring from the agent. A new --standalone CLI flag preserves agent-less operation for tests and air-gapped bootstrap. The broker-unreachable path logs a loud WARN and falls back to the escape hatch rather than silently collecting. Unit 2 — Machine-checked <1ms p99 latency SLO. New latency_p99_slo criterion bench in benches/ipc_performance.rs with `const LATENCY_P99_SLO: Duration = Duration::from_millis(1)` and panic-on-breach. A dedicated eventbus-latency-slo job in .github/workflows/benchmarks.yml runs it on Linux and macOS. Observed p99 on macOS aarch64: ~21us (48x under SLO). Unit 3 — Doc-truth sync across IMPLEMENTATION_SUMMARY.md, VALIDATION_CHECKLIST.md, COMPREHENSIVE_REVIEW.md, and README.md. The largest correction removes the "Pause/Resume stubbed" claim — rpc.rs:1862-1950 delegates to ProcessManager::{pause,resume}_collector, they are fully implemented. Embedded validation commands re-verified against current state; line-count expectations refreshed. Unit 4 — End-to-end multi-collector coordination test (tests/e2e_multi_collector.rs). Five scenarios exercising the real broker, task distributor, and result aggregator with two simulated collector clients: load balancing across queue group members, broadcast config reload, failover after deregister, result aggregation with correlation IDs, and wildcard observer. Scope-limited to in-process clients because cross-OS-process subscription registration is a latent transport-layer gap tracked separately. Unit 5 — Acceptance evidence artifact (docs/END-297-acceptance-evidence.md) mapping every acceptance criterion to code, tests, and benchmarks with repo-relative paths and independently runnable reproduction commands.

The new API lets subscribers opt in (default `false` preserves legacy behavior), and procmond now subscribes to `control.collector.lifecycle` and waits for `BeginMonitoring` before calling `begin_monitoring()`. A new `--standalone` CLI flag preserves agent-less operation for tests and bootstrap. The broker-unreachable path logs a loud WARN and falls back to the escape hatch rather than silently collecting. + +2. **Unit 2 — `latency_p99_slo` benchmark with CI gate.** The ticket's "\<1ms p99 latency" acceptance criterion is now a machine-checked assertion in a dedicated criterion bench target that panics if p99 exceeds `Duration::from_millis(1)`. The `eventbus-latency-slo` job in [`.github/workflows/benchmarks.yml`](../../.github/workflows/benchmarks.yml) runs it on Linux and macOS; Windows and FreeBSD are informational per the plan's OS-support posture. + +3. **Unit 4 — `e2e_multi_collector` integration test.** Five scenarios exercising the real broker, task distributor, and result aggregator with two simulated collector clients: load balancing, broadcast config reload, failover on deregister, result aggregation with correlation IDs, and wildcard observer. Runs in under a second; scope-limited to in-process clients because cross-OS-process subscription registration is a latent transport-layer gap (see note below). + +4. **Unit 3 — doc-truth sync.** `IMPLEMENTATION_SUMMARY.md`, `VALIDATION_CHECKLIST.md`, `COMPREHENSIVE_REVIEW.md`, and `README.md` were updated to match actual behavior. The largest correction was removing the "Pause/Resume stubbed" claim — [`daemoneye-eventbus/src/rpc.rs`](../src/rpc.rs) lines 1862-1950 delegate to `ProcessManager::{pause,resume}_collector`, they are not stubbed. Line-count expectations in `VALIDATION_CHECKLIST.md` were refreshed against current reality. Stale completion-percentage claims were dropped. + +## Known Latent Gaps (Not Blocking Closure) + +These were surfaced during the closure pass but are explicitly out of scope for END-297 and tracked separately: + +- **Cross-OS-process subscription registration over `interprocess`.** The broker does not currently run a per-connection receive loop that handles subscribe-request protocol messages from remote clients. `ClientConnectionManager::subscribe_client` exists but is only exercised by an in-process test in [`daemoneye-eventbus/src/transport.rs`](../src/transport.rs). This means the `e2e_multi_collector` test scenarios deliberately use in-process clients. The broker's routing, load balancing, queue groups, and failover logic are all exercised through the real code paths, but genuinely separate OS processes subscribing via Unix socket is a follow-on transport-layer item. +- **File-size hygiene.** [`daemoneye-eventbus/src/rpc.rs`](../src/rpc.rs) (2789 lines) and [`daemoneye-eventbus/src/broker.rs`](../src/broker.rs) (1371 lines) exceed the AGENTS.md 500-600 line guideline. A separate refactor ticket is the right home for that. +- **`SECURITY_TODO` at [`daemoneye-eventbus/src/task_distribution.rs:149`](../src/task_distribution.rs).** The `CollectorStatus::ShuttingDown` variant is reserved for Task 2.5.5 graceful-shutdown coordination and is marked `#[allow(dead_code)]` intentionally. +- **Coverage metrics.** `cargo llvm-cov` is not yet gated in CI.

All changes target narrow surfaces; no new behavior is added beyond closing review gaps. Safe-auto fixes (previously applied, included here for trail): - client.rs: 5 uninlined-format-arg violations fixed to comply with the AGENTS.md zero-warnings clippy rule (review P1 project-standards). - ipc_performance.rs: p99 index changed from `(N*99)/100` to the correct nearest-rank `ceil(N*99/100) - 1` (review P3 correctness COR-002). - ipc_performance.rs: removed Atlassian Jira URL from doc comment per AGENTS.md open-core hygiene; bare `END-297` label retained. Gated fixes approved in this pass: - A. procmond/main.rs: `_events_rx` from `subscribe_with_control` is now drained by a background task rather than dropped. Eliminates lifetime-long `warn!` spam on every Event matching the subscription patterns (review P1 COR-001 / ADV-002). - B. procmond/main.rs: Registration failure now forces standalone_mode instead of falling into subscribe-then-wait. Matches the warning message's claim; prevents indefinite block waiting for a BeginMonitoring that an unregistered collector will never receive (review P1 COR-003). - C. procmond/main.rs: `lifecycle_wait_task` now uses `tokio::time::timeout(BEGIN_MONITORING_WAIT_TIMEOUT, recv)` with a 60s deadline, and handles both timeout and channel-closed cases by logging ERROR and falling back to standalone collection. Closes the indefinite-idle recovery gap (review P1 REL-001 / REL-002 / ADV-004). - D. client.rs + procmond/main.rs: Subscription topology logs (per- collector IDs, topic patterns) demoted from info! to debug! so they stay out of default-level logs that may ship to less-trusted SIEM pipelines (review P2 SEC-004). - E. client.rs test: `test_control_message_not_delivered_when_not_opted_in` now retains the event channel receiver and asserts try_recv returns Empty, proving Control does not leak onto the Event channel for opt-out subscribers (review P2 testing T-004). - F. client.rs: Extracted `subscription_matches_topic(patterns, topic)` helper to remove byte-for-byte duplication between handle_event_message_internal and handle_control_message_internal (review P2 maintainability M-001). Coverage: - cargo clippy --workspace --all-targets -- -D warnings: clean - cargo fmt --all --check: clean - 193 eventbus + 631 procmond + 169 agent tests pass Deliberately NOT addressed in this pass (tracked for follow-up): - P0 SEC-001: no access-control enforcement on Control-topic subscriptions -- needs design review, not a quick patch. - P1 startup race (heartbeat-before-subscribe) -- needs protocol decision (oneshot vs ack-and-retry). - Escape-hatch audit ledger, postcard drift, standalone privilege check, RPC topic routing, collector-core parity -- architectural. - Missing tests for new procmond happy path / standalone branches -- scope for follow-up PR.

Narrowed the subscription to lifecycle-only; upgraded the topic-mismatch branch from debug! to warn! as a defensive guard. RPC-over-bus wiring (a separate subscription owned by RpcServiceHandler) is out of scope for this closure pass and tracked as follow-up per the END-297 plan. - .github/workflows/benchmarks.yml (thread 2, @coderabbitai): the `eventbus-latency-slo` job was gated on `workflow_dispatch` only, so latency regressions could merge without the SLO ever firing. Added a narrow-path `pull_request` trigger (daemoneye-eventbus/**, collector-core/**, benchmarks.yml) so the SLO gate runs on PRs. Gated the informational `benchmarks` and `load-tests` jobs to workflow_dispatch only so PR CI cost stays contained. - procmond/tests/actor_mode_integration_tests.rs (thread 4, @coderabbitai): replaced the Display-string assertion in `test_subscribe_with_control_fails_when_not_connected` with a `matches!(err, EventBusConnectorError::Connection(_))` variant check so harmless message rewording can't break the test. - docs/src/technical/eventbus-architecture.md (thread 5, @coderabbitai): scoped the p99 latency SLO claim explicitly to Linux/macOS CI.

Thread 6 (@coderabbitai, Critical — main.rs:468): the read guard on `event_bus: Arc>` was held across the `.await` on `subscribe_with_control`, violating the workspace rule `clippy::await_holding_lock = "deny"`. Fix: wrap the connector's inner `EventBusClient` in `Arc` so callers can clone the handle out of a brief read-lock and perform async work unlocked. New `EventBusConnector::client_arc()` accessor returns `Option>`. In main.rs the call site now acquires the read guard only long enough to clone the Arc, drops it, then awaits `client.subscribe_with_control(subscription)` against the owned Arc. Connector shutdown uses `Arc::into_inner` to reclaim ownership when the Arc's strong_count is 1; if outstanding Arc refs remain (in-flight subscribe), it logs a warn and drops its handle so the client's background tasks exit naturally. 2. Thread 7 (@coderabbitai, Major — main.rs:577): the per-iteration `tokio::time::timeout` around `control_rx.recv()` reset the 60s window on every non-lifecycle message, so a chatty control stream could starve `BeginMonitoring` indefinitely. Fix: compute one absolute deadline once before the loop using `Instant::now().checked_add(BEGIN_MONITORING_WAIT_TIMEOUT)` and use `tokio::time::timeout_at(deadline, ...)` inside. The window is now absolute — non-lifecycle message traffic can no longer reset it.

The initial implementation acquired the read guard and then awaited on `bus_guard.subscribe_with_control(...)` — the guard was live across the `.await` point, which the workspace rule `clippy::await_holding_lock = "deny"` correctly flagged. + +The pattern below is the canonical project-wide fix for this class of problem. It applies anywhere a resource lives inside a `tokio::sync::Mutex` or `RwLock` and callers need to issue async calls on it. + +The `clippy::await_holding_lock = "deny"` rule was originally not inherited on the `collector-core` and `daemoneye-eventbus` crates (session history); once the workspace-lints inheritance landed, any async call made while holding a lock guard started failing to compile. This pattern is the canonical response — expect it to be needed again whenever an `Arc>` field is introduced (session history). + +## Guidance + +### 1. The anti-pattern: lock guard held across `.await` + +```rust +// WRONG — read guard is live when .await executes +let subscribe_result = { + let bus_guard = event_bus.read().await; // guard acquired + bus_guard + .subscribe_with_control(subscriber_id, topics) + .await // clippy::await_holding_lock fires here +}; +``` + +Other tasks needing the lock are blocked for the full duration of the async call, which can be unbounded. The lint denies this shape workspace-wide. + +### 2. The fix: clone an `Arc` inside a short guard, drop it, then await + +Wrap the inner resource in `Arc` inside the lockable container. Add a cheap accessor that clones the `Arc`. Callers acquire the guard only long enough to take the clone, drop the guard, then `.await` on the owned `Arc`. + +In `procmond/src/event_bus_connector.rs`: + +```rust +pub struct EventBusConnector { + // store the client behind Arc so callers can clone it out of the lock + client: Option>, + /* ... */ +} + +/// Cheap accessor — just clones the Arc pointer. No async, no I/O. +#[must_use] +pub fn client_arc(&self) -> Option> { + self.client.clone() +} +``` + +At the call site in `procmond/src/main.rs`: + +```rust +// CORRECT — guard scope ends before .await +let client_arc = { + let bus_guard = event_bus.read().await; + bus_guard.client_arc() // clone; guard drops at block end +}; +let subscribe_result = match client_arc { + Some(client) => client.subscribe_with_control(subscription).await, + None => return Err(anyhow::anyhow!("not connected to broker")), +}; +``` + +The `{ let bus_guard = ...; bus_guard.client_arc() }` block shape is what makes the lint pass — the guard drops at the end of the block, before the expression value feeds into the subsequent `.await`. + +### 3. `Arc::into_inner` for shutdown when the inner type consumes `self` + +Some inner types have `async fn shutdown(self) -> Result<(), E>` that consumes `self`. When the normal value is shared via `Arc`, use `Arc::into_inner` to reclaim ownership only when the strong count is 1 — if any clones are in flight, log and drop so background tasks exit naturally. + +From `procmond/src/event_bus_connector.rs`: + +```rust +if let Some(client_arc) = self.client.take() { + match Arc::into_inner(client_arc) { + Some(client) => { + if let Err(e) = client.shutdown().await { + error!(error = %e, "Error during client shutdown"); + } + } + None => { + warn!( + "EventBusClient has outstanding Arc references; skipping \ + explicit shutdown - background tasks will exit when the \ + Arc drops" + ); + } + } +} +``` + +`self.client.take()` removes the connector's own reference. If `Arc::into_inner` returns `None`, outstanding callers still hold the client alive; they will drop it when they go out of scope and the client's `Drop` / background-task shutdown paths take over. + +### 4. Single absolute deadline with `timeout_at` for wait loops + +When waiting for a signal across multiple loop iterations, compute the deadline once before the loop. `tokio::time::timeout(dur, fut)` applied per iteration resets the window on every received message, which lets a chatty or adversarial stream push the deadline out indefinitely (session history: this was a CodeRabbit Major finding on the first implementation). + +From `procmond/src/main.rs` (`lifecycle_wait_task`): + +```rust +// CORRECT — deadline is fixed once; cannot be reset by arriving messages +let now = tokio::time::Instant::now(); +let deadline = now + .checked_add(BEGIN_MONITORING_WAIT_TIMEOUT) + .unwrap_or(now); +loop { + match tokio::time::timeout_at(deadline, control_rx.recv()).await { + Ok(Some(msg)) if msg.topic == lifecycle_topic => { + /* transition to running */ + return; + } + Ok(Some(_)) => { /* non-lifecycle — keep waiting */ } + Ok(None) => { /* channel closed — fallback */ return; } + Err(_elapsed) => { /* timed out — fallback */ return; } + } +} +``` + +`checked_add` + `unwrap_or(now)` is required because the workspace enables `clippy::arithmetic_side_effects = "deny"`; the overflow case is treated as an immediate deadline (fails fast) rather than silently panicking. + +## Why This Matters + +- **Lock contention under load.** An async call holding a lock can take tens to hundreds of milliseconds. Every other task needing the lock — including read-only observers — blocks for that duration. Under high throughput the effect compounds. +- **Workspace clippy enforcement is hard.** `await_holding_lock = "deny"` is workspace-wide, and the `--all-targets` pre-commit hook treats any offending shape as a build failure, not a warning. The `Arc`-clone pattern is the canonical fix the lint expects. +- **Shutdown-race survivability.** `Arc::into_inner` is the safe way to call a consuming `shutdown(self)` on a shared value. The fallback (log + drop) ensures shutdown never hangs on in-flight subscribers. +- **Deadline absoluteness matters.** `timeout_at` makes the wait window honest about the operator's intent.

Three real issues (one bug, one design issue, one policy gap) plus two doc mismatches: - procmond/src/main.rs (copilot, Critical): the heartbeat task was spawned BEFORE the control subscription. Tokio's interval ticks immediately on first poll, so a heartbeat could be published before the subscription was registered with the broker - causing an agent BeginMonitoring broadcast to be delivered to zero subscribers and procmond to fall back to a 60s timeout. Moved the heartbeat spawn to AFTER the subscribe block completes; updated the ordering comment to describe the real invariant. - daemoneye-eventbus/src/client.rs + procmond/src/event_bus_connector.rs (copilot, Major): on connector shutdown with outstanding Arc clones, the previous implementation skipped client.shutdown() entirely, leaving the broker connection alive and background tasks running until the last clone dropped. Added a non-consuming EventBusClient::shutdown_signal(&self) that fires the broadcast shutdown channel. Connector shutdown now always calls shutdown_signal first (stops background tasks regardless of Arc count), then attempts Arc::into_inner for the full consuming shutdown when possible. No task leak on shutdown. - AGENTS.md (copilot, Minor): the "No Auto-Commits" guideline had been replaced with "No Merging" without preserving the auto-commit prohibition. Restored "No Auto-Commits" as an explicit rule #2 alongside "No Merging". - daemoneye-eventbus/tests/e2e_multi_collector.rs (copilot, two docs): - File header previously claimed "Integration tests are code inside #[cfg(test)] by convention"; corrected - integration tests in tests/ compile as their own binary crate with no #[cfg(test)] wrapping. - collect_until doc comment previously claimed "Uses tokio::select!" but the impl is a try_recv drain loop with a short sleep. Rewrote the doc to describe the actual polling approach.

No behavior changes — every edit is a mechanical clippy suggestion. Changes by lint: - duration_suboptimal_units: replaced Duration::from_secs(60) with Duration::from_mins(1), from_secs(300) with from_mins(5), from_secs(3600) with from_hours(1), from_millis(1000) with from_secs(1), etc. across daemoneye-lib, daemoneye-eventbus, collector-core, daemoneye-agent, and procmond. Removed now-redundant inline unit comments. - map_unwrap_or: rewrote .map(f).unwrap_or(x) on Result as .map_or(x, f) in daemoneye-lib, collector-core, and daemoneye-agent. Two sites in trigger.rs flagged as further simplifiable became .is_ok_and(|x| ...). - manual_checked_ops: replaced if d == 0 { 0 } else { a / d } in daemoneye-eventbus/src/process_manager.rs with checked_div.unwrap_or(0). Dropped the now-unnecessary arithmetic_side_effects / integer_division allow attributes on that block.

charset=UTF-8 Content-Transfer-Encoding: 8bit Applies the in-scope fixes from the final comprehensive review (6 reviewers). Non-blocking items are deferred to focused follow-up PRs and logged in the acceptance-evidence "Post-Merge Follow-ups" section so they travel with this PR. Fixed in this commit: - procmond/src/main.rs: treat ActorError::ChannelClosed as a fatal condition. Added begin_monitoring_or_exit() helper and routed all four fallback paths (--standalone, broker-unreachable, channel-closed, wait-timeout) plus the lifecycle-signal success path through it. ChannelClosed means the actor task crashed and procmond has become a zombie; exiting non-zero lets the supervisor restart. ChannelFull and other transient errors stay logged but non-fatal. (silent-failure-hunter C1) - daemoneye-eventbus/docs/END-297-acceptance-evidence.md: demote R14 (Control-message delivery) from fully satisfied to partial (in- process only). Added note that production procmond will hit the 60s wait timeout on every startup until the cross-process subscription- registration gap closes. (code-reviewer I-1) - procmond/src/main.rs startup-ordering comment: rewrote to describe the real invariant. Previous wording claimed a causal heartbeat- triggers-broadcast chain that doesn't exist in the current agent code. (code-reviewer I-3) - daemoneye-eventbus/src/client.rs: fix unreachable "already signaled" path in shutdown_signal rustdoc. The &self receiver proves the consuming shutdown() has not run; only "no live receivers" is reachable. (comment-analyzer S4a) - daemoneye-eventbus/benches/ipc_performance.rs: drop misleading "x86_64" claim from the SLO cfg comment. The #[cfg] gate is target_os only; macOS aarch64 already exercises the assertion (observed p99 ~21µs). (comment-analyzer S4b) - procmond/src/main.rs composition-root comment: remove the "statelessness invariant ... across trust domains" phrasing that does not appear in MultiAlgorithmHasher rustdoc. Replaced with the accurate claim (Send + Sync, no per-request mutable state). (comment-analyzer S4c) - procmond/src/main.rs: drop the "(ADR referenced in END-297 evidence)" citation — no ADR link exists in the evidence artifact. Point directly to the plan document. (comment-analyzer S4d) - daemoneye-eventbus/src/client.rs test docstring: correct the TryRecvError::Full reference — mpsc::error::TryRecvError has only Empty and Disconnected variants; a routed-to-wrong-channel bug would produce Ok(_), not any error variant. (comment-analyzer I6) - daemoneye-eventbus/src/message.rs: EventSubscription docstring explains why #[non_exhaustive] wasn't applied (FRU forbidden cross-crate, requires builder-pattern refactor) and points to the follow-up. Deferred (logged in Post-Merge Follow-ups section of the acceptance- evidence artifact): - Full audit-ledger integration on the 5 fallback paths (P1) - Missing tests for subscribe-then-wait / --standalone / off-topic branch / TrySendError::Full (P1) - Remove EventBusConnector.connected bool drift risk (P2) - #[non_exhaustive] + builder-pattern refactor (P2) - Type-design polish — collapse include_control, shutdown_signal enum (P3) - Simplification opportunities — try_subscribe_control helper, collect_until doc, shutdown canonical example (P3) Coverage: - cargo +1.95 clippy --workspace --all-targets -- -D warnings: clean - cargo +1.95 fmt --all --check: clean - 193 eventbus + 631 procmond + 169 agent + 249 collector-core tests all pass Refs: END-297, PR #178 Signed-off-by: UncleSp1d3r --- daemoneye-eventbus/benches/ipc_performance.rs | 8 +- .../docs/END-297-acceptance-evidence.md | 52 ++++++--- daemoneye-eventbus/src/client.rs | 11 +- daemoneye-eventbus/src/message.rs | 9 ++ procmond/src/main.rs | 108 ++++++++++++------ 5 files changed, 124 insertions(+), 64 deletions(-) diff --git a/daemoneye-eventbus/benches/ipc_performance.rs b/daemoneye-eventbus/benches/ipc_performance.rs index 5f93405a..94ab12ad 100644 --- a/daemoneye-eventbus/benches/ipc_performance.rs +++ b/daemoneye-eventbus/benches/ipc_performance.rs @@ -390,10 +390,10 @@ fn latency_p99_slo(c: &mut Criterion) { LATENCY_P99_SLO, );

Addressed now. Critical fixes: - Happy-path hang (silent-failure C-1). The prior helper treated ChannelFull as non-fatal on every call site. But the agent's BeginMonitoring broadcast is at-most-once, and the standalone opt-in path is a one-shot entry — if ChannelFull hits on either lifecycle-signal or standalone-mode, the signal is consumed with no retry, leaving procmond hung in WaitingForAgent forever. This is the exact zombie mode the helper was created to prevent. Introduced a typed BeginMonitoringReason enum distinguishing one-shot paths (StandaloneMode, LifecycleSignal) from degraded-fallback paths (BrokerUnreachable, ChannelClosed, WaitTimeout) and made the helper's error policy path-dependent: ChannelFull is recoverable only on degraded-fallback paths; on one-shot paths every actor error is fatal. - Non-exhaustive ActorError drift (silent-failure C-2). The prior helper's catch-all Err(_) branch silently absorbed any future ActorError variant into the "log-and-continue" path. Since ActorError is marked #[non_exhaustive], new variants would inherit the wrong-default without a compiler warning. Inverted the default: default-fatal posture now explicitly handles ChannelFull and exits on anything else, including ChannelClosed, ResponseDropped, and any future variant a reviewer adds. - Typed reason enum (silent-failure S-2). Replaced the five &str literals with a BeginMonitoringReason enum, so misspellings at call sites are compiler errors and log-correlation queries are reliable. Accuracy fixes (comment-analyzer): - The #[allow(clippy::exit, reason = ...)] rationale incorrectly claimed that returning Err to main() would produce a clean exit supervisors wouldn't restart. In fact, anyhow::Result's Termination impl returns non-zero; the real reason exit() is needed is that three of five call sites are inside tokio::spawn tasks where Err return propagates nowhere. Rewrote the rationale accordingly. - The EventSubscription docstring pointed at a file (docs/todos/end-297-type-design-polish.md) that doesn't exist in the repo — same class of bug the prior commit was meant to fix. Redirected to the EventSubscription bullet of the "Post-Merge Follow-ups" section of END-297-acceptance-evidence.md, which is where the deferral is actually tracked. - The evidence doc's simplification-opportunities bullet cited line range 476-538 for the nested match, which was off by ~40 lines after this commit's own insertion. Dropped the specific line range and described the match shape instead so the reference stays valid as the file grows. - Heartbeat-ordering comment now explicitly states the placement is "defensive only" — no code path today routes heartbeats into the broadcast trigger, and the subscribe/spawn order could be reversed without breaking correctness. Previous wording implied a causal chain that doesn't exist.

All changes are additive or simplifying — no existing recipes break. Structural changes: - Simplified format-docs. Replaced the 60-char existence-check with `@mise_exec mdformat .`. mise guarantees mdformat is present; excludes (target/, node_modules/) already live in .mdformat.toml. Removed the stale "mdformat-install" citation (no such recipe existed). Same recipe now works on Windows and Unix — no platform split needed. - Factored coverage into a private `_coverage +args` helper (the `cargo llvm-cov nextest` command line now lives in one place). Added `coverage-report` (HTML + open browser) and `coverage-summary` (terminal-only). `coverage-check` is now a one-liner: `just _coverage --fail-under-lines 9.7`. RUSTFLAGS='--cfg coverage' lets future code gate expensive paths with `#[cfg(coverage)]` when coverage runs get slow. - Added `lint-actions` recipe — `actionlint .github/workflows/*.yml` with release.yml ignored (GoReleaser-generated). Already enforced via pre-commit; now runnable standalone. - Renamed `lint-docs` → `lint-rustdoc` for clarity (checks rustdoc comments, not markdown). Added `lint-md` that runs markdownlint-cli2 + lychee link-validation — catches the class of stale cross-reference that comment-reviewer rounds keep finding. Top-level `lint` now calls both. - Marked `pre-commit-run` as `[private]`. It's only invoked via `check` and `ci-check`; no reason to clutter `just --list`. - Added aliases for format/lint symmetry: - `format-rust := fmt` - `format-md := format-docs` - `format-just := fmt-justfile` - `lint-just := lint-justfile` - Added `[group(...)]` annotations: bench/*, goreleaser/*, release/* now cluster together in `just --list`. Bug fixes: - Double space in goreleaser-build-target Windows variant (line 341). - Orphaned "# Check coverage thresholds" + TODO comment collapsed into a single descriptive comment. Verified: - `just lint-justfile` clean (passes its own formatter). - `just --list` renders cleanly with groups. - `just format-docs` runs (no platform-split needed). - `just lint-actions` runs (no findings).

The new API lets subscribers opt in (default `false` preserves legacy behavior), and procmond now subscribes to `control.collector.lifecycle` and waits for `BeginMonitoring` before calling `begin_monitoring()`. A new `--standalone` CLI flag preserves agent-less operation for tests and bootstrap. The broker-unreachable path logs a loud WARN and falls back to the escape hatch rather than silently collecting. - -2. **Unit 2 — `latency_p99_slo` benchmark with CI gate.** The ticket's "\<1ms p99 latency" acceptance criterion is now a machine-checked assertion in a dedicated criterion bench target that panics if p99 exceeds `Duration::from_millis(1)`. The `eventbus-latency-slo` job in [`.github/workflows/benchmarks.yml`](../../.github/workflows/benchmarks.yml) runs it on Linux and macOS; Windows and FreeBSD are informational per the plan's OS-support posture. - -3. **Unit 4 — `e2e_multi_collector` integration test.** Five scenarios exercising the real broker, task distributor, and result aggregator with two simulated collector clients: load balancing, broadcast config reload, failover on deregister, result aggregation with correlation IDs, and wildcard observer. Runs in under a second; scope-limited to in-process clients because cross-OS-process subscription registration is a latent transport-layer gap (see note below). - -4. **Unit 3 — doc-truth sync.** `IMPLEMENTATION_SUMMARY.md`, `VALIDATION_CHECKLIST.md`, `COMPREHENSIVE_REVIEW.md`, and `README.md` were updated to match actual behavior. The largest correction was removing the "Pause/Resume stubbed" claim — [`daemoneye-eventbus/src/rpc.rs`](../src/rpc.rs) lines 1862-1950 delegate to `ProcessManager::{pause,resume}_collector`, they are not stubbed. Line-count expectations in `VALIDATION_CHECKLIST.md` were refreshed against current reality. Stale completion-percentage claims were dropped. - -## Known Latent Gaps (Not Blocking Closure) - -These were surfaced during the closure pass but are explicitly out of scope for END-297 and tracked separately: - -- **Cross-OS-process subscription registration over `interprocess`** (scope-reducing R14 from full to partial — see matrix row 14). The broker does not currently run a per-connection receive loop that handles subscribe-request protocol messages from remote clients. `ClientConnectionManager::subscribe_client` exists but is only exercised by an in-process test in [`daemoneye-eventbus/src/transport.rs`](../src/transport.rs). This means the `e2e_multi_collector` test scenarios deliberately use in-process clients. The broker's routing, load balancing, queue groups, and failover logic are all exercised through the real code paths, but genuinely separate OS processes subscribing via Unix socket is a follow-on transport-layer item. **In production today, a separately-spawned procmond will hit its 60s `BEGIN_MONITORING_WAIT_TIMEOUT` and fall back to standalone collection on every startup until this gap closes.** -- **File-size hygiene.** [`daemoneye-eventbus/src/rpc.rs`](../src/rpc.rs) (2789 lines) and [`daemoneye-eventbus/src/broker.rs`](../src/broker.rs) (1371 lines) exceed the AGENTS.md 500-600 line guideline.

[`COMPREHENSIVE_REVIEW.md`](../COMPREHENSIVE_REVIEW.md) tracks this as a medium-priority follow-up. - -## Post-Merge Follow-ups - -Surfaced by the final comprehensive review (6 reviewers), deferred to focused follow-up PRs rather than expanding this already-large closure pass: - -- **Audit-ledger writes on fallback paths** (P1, security-relevant). Every fallback in `procmond/src/main.rs` (operator-opt-in standalone, registration failure, broker-unreachable subscribe fail, lifecycle-wait timeout, lifecycle-wait channel closed) emits a `warn!`/`error!` log but does not write to the BLAKE3 hash-chained audit ledger. An attacker who disables the agent can force uncoordinated collection with no tamper-evident record. Work required: decide on signing-key scope for procmond, initialize the `AuditLedger` (see `daemoneye-lib/src/crypto.rs:172+`) in procmond startup, wire signed entries at the five transition sites, add an integration test. - -- **Test coverage for new procmond startup flow** (P1). Four specific paths still untested at HEAD: subscribe-then-wait happy path (no workspace-level test delivers `BeginMonitoring` through the broker to a subscriber and asserts the Running transition); `--standalone` / `PROCMOND_STANDALONE=1` runtime behavior (only CLI-help snapshot exists); `lifecycle_wait_task` non-lifecycle continue branch; `TrySendError::Full` backpressure drop in `handle_control_message_internal`. Combined regression surface is narrow but real. - -- **Remove `EventBusConnector.connected` bool** (P2). Duplicates `self.client.is_some()` and can drift — `try_reconnect` error paths at lines 685 and 861 set `connected = false` but leave `client = Some(...)`. Deferred from this PR because alignment requires auditing each error path to decide whether to drop the client there. - -- **`#[non_exhaustive]` on `EventSubscription`** (P2). Attempted in this PR; requires a builder or `with_*` setter API because cross-crate struct-literal construction (including FRU) is forbidden for non-exhaustive types, which would cascade through `collector-core`, tests, and benches. Docstring at [`daemoneye-eventbus/src/message.rs`](../src/message.rs) notes the deferral. - -- **Type-design polish** (P3). Collapse `EventSubscription::include_control` into the method choice (`subscribe()` vs `subscribe_with_control()`); upgrade `EventBusClient::shutdown_signal(&self) -> bool` to a three-variant enum (`Sent` / `AlreadyShutDown` / `NoReceivers`); either reject `include_control=false` from `subscribe_with_control()` or change return to `(Receiver, Option>)`. - -- **Simplification opportunities** (P3). Extract `try_subscribe_control` helper in `procmond/src/main.rs` to flatten the nested match in the subscribe block (the `match client_arc { Some => ..., None => ... }` followed by `match subscribe_result { Ok => ..., Err => fallback }` — exact line range shifts as the file grows); consolidate the channel-closed and timeout fallback arms in `lifecycle_wait_task` (now-shared `begin_monitoring_or_exit` helper already does this at the call-site level); add partial-count warning to `collect_until` rustdoc; promote the `Arc::into_inner` shutdown pattern to a canonical example on `shutdown_signal`'s rustdoc; pull `DEFAULT_SUBSCRIPTION_CAPACITY = 1000` into a named `const`. - -## Review Decision - -All acceptance criteria have evidence.

Cold build on ubuntu-latest/macos-latest exceeds 15 min. Add Swatinem/rust-cache keyed on OS + Cargo.lock so the second run onward restores target/ and completes well under the timeout.
