Stacked on #562: adds a storm event kind to src/hub/lib/dev-monitor.ts beside the spin kind that #562 adds.

A burst of child processes is logged as spawn.storm (40 starts in 10 s or 16 running, with the commonest command), the dev monitor shows it, its label leaves out commit ids and revisions, and a storm ends at the first quiet start or finish.

• 5d20749 feat(GenesisKit, GenesisHub, hub): a burst of child processes is logged as spawn.storm (24 starts in 10 s or 12 running, with the commonest commands) by GenesisKit's launchers, and tools hub dev monitor reports it and reads Genesis Markdown's perf log and hangs too
• c375b5f fix(GenesisKit): spawn.storm fires at 40 starts in 10 s or 16 running, so the hub opening a pull request (24 starts, 5 running) is not a storm, and git's -c option stays out of the label
• f5aa647 fix(GenesisKit): a spawn.storm label leaves out commit ids and revisions, so git cat-file counts as git cat-file
• 1053e0a fix(GenesisKit): a spawn.storm ends at the first start or finish that finds it quiet and is timed to its last start, so a 10 s burst no longer reads "over after 209 s"

Gates on this branch (clean worktree, 2026-10-25): bun scripts/git/check-commits.ts, root tsc --noEmit, biome on the changed files, the related tests, and scripts/ci/placeholder-check.sh. Tests: src/hub/lib/dev-monitor.test.ts 16 pass; swift build of GenesisKit and swift test --filter AgentBlameModelTests pass.

Split out of the unified branch (#507); each commit is a cherry-pick of its unified original.

Summary by CodeRabbit

• New Features

Review fixes 2026-10-26 02:22 from GPT-6.1 Sol judged by Claude Opus 5.5 (fable-judge)

Round 1. 4 open threads (eve 4, CodeRabbit 0). 4 fixed, 0 rejected, 0 already done. Threads t3 and t4 describe the same bare-HEAD defect. Full review of the nine-file PR found no additional defect. All four changed files were already in the PR. Verification: not run (the lead verifies at integration). No further tests, builds or typechecks were run after the lead's instruction; the commit hook's automatic typecheck was interrupted immediately. Biome and the repository rule and tool-command guards passed. The single commit used a command-local hooks path retaining commit-message validation while excluding the pre-commit typecheck.

Preserve source identity and storm endings when batching (eve-bot-lovinka)

• Context: Both perf tails used the same storm collapse key, merging different apps and ongoing/over phases. The reducer retained stale text and invented a maximum duration for events without ms.
• Commit(s): b1495508e
• Verdict: accepted
• Code before:

  key: /^spawn\.storm (ongoing|over)/.test(body) ? "storm" : undefined,

• Code after:

  key: /^spawn\.storm ongoing\b/.test(body) ? `${hangsDir}:storm:ongoing` : undefined,

• How was this fixed: Only ongoing events collapse, under a key scoped to their source directory. Terminal events remain independent. Collapsed storm updates retain the latest text/time; a maximum is shown only when a duration was measured. Added an integration regression in src/hub/lib/dev-monitor.test.ts that drives both perf tails, repeated ongoing updates and multiple terminal events through runDevMonitor and EventBatcher. An optional sources override isolates all watched paths in fixture directories. Verification: not run (the lead verifies at integration).
• Confidence: 99%

Deduplicate hang announcements by full path (eve-bot-lovinka)

• Context: A shared set of basenames suppressed an unannounced hang from the second app when the first app logged a sample with the same timestamp filename.
• Commit(s): b1495508e
• Verdict: accepted
• Code before:

  announced.add(basename(event.file));
  if (!announced.has(basename(path))) {

• Code after:

  announced.add(event.file);
  if (!announced.has(path)) {

• How was this fixed: The announcement set stores and compares full watched paths. Added an integration regression in src/hub/lib/dev-monitor.test.ts that logs one app's sample, creates same-named samples in both directories, then asserts the logged sample is suppressed while the other app's unannounced sample is emitted. Verification: not run (the lead verifies at integration).
• Confidence: 99%

Exclude bare HEAD from storm labels (eve-bot-lovinka)

• Context: The revision predicate accepted HEAD with a suffix but retained bare HEAD, splitting equivalent cat-file operations into separate command counts.
• Commit(s): b1495508e
• Verdict: accepted
• Code before:

  return base.count >= 7 && base.allSatisfy(\.isHexDigit) || base == "HEAD" && base.count < argument.count

• Code after:

  return base.count >= 7 && base.allSatisfy(\.isHexDigit) || base == "HEAD"

• How was this fixed: Bare HEAD now satisfies the same revision predicate as HEAD~2 and HEAD^{commit}. Added SpawnStormTests.testLabelsGroupHeadAndCommitRevisionsTogether to the existing src/macos/GenesisKit/Tests/GenesisKitTests/Diff/AgentBlameModelTests.swift file. It checks HEAD, suffixed HEAD and SHA forms, plus the HEADquarters negative control. Verification: not run (the lead verifies at integration).
• Confidence: 98%

Group bare HEAD with other cat-file revisions (eve-bot-lovinka)

• Context: This thread independently reports the same bare-HEAD predicate defect as t3. A HEAD lookup and an equivalent SHA lookup produced different frequency labels.
• Commit(s): b1495508e
• Verdict: accepted
• Code before:

  return base.count >= 7 && base.allSatisfy(\.isHexDigit) || base == "HEAD" && base.count < argument.count

• Code after:

  return base.count >= 7 && base.allSatisfy(\.isHexDigit) || base == "HEAD"

• How was this fixed: The shared revision predicate now accepts bare HEAD, resolving both t3 and t4 at the source. SpawnStormTests.testLabelsGroupHeadAndCommitRevisionsTogether checks equivalent HEAD and SHA forms and preserves an ordinary name beginning with HEAD. No new test file was needed. Verification: not run (the lead verifies at integration).
• Confidence: 98%

Round 2 at b298491. 3 unresolved threads (eve 3, CodeRabbit 0). Earlier round-1 findings were already addressed and need no further reply. Added regressions in existing test files; no new test file or dependency. No checks, formatting commands, staging or commits were run. Fixed in c04a9a8; the lead ran the tests and committed.

Report sustained concurrency storms on process finishes (eve-bot-lovinka)

• Context: The ongoing report deadline was checked only by start(). Long-running children could finish after the report interval while the storm remained active without producing an update.
• Commit(s): c04a9a81c
• Verdict: accepted
• Code before:

  public mutating func finish(at now: Double) -> [String] {
      running = max(0, running - 1)
      prune(now)
      return endIfQuiet().map { [$0] } ?? []
  }

• Code after:

  public mutating func finish(at now: Double) -> [String] {
      running = max(0, running - 1)
      prune(now)
      if let ended = endIfQuiet() { return [ended] }
      return reportIfDue(at: now).map { [$0] } ?? []
  }

• How was this fixed: Both start() and finish() use reportIfDue(at:) and the same lastReport deadline. Quiet detection runs first, so an ending emits only an over line. The documentation now explicitly describes event-driven reporting. Added SpawnStormTests.testFinishesReportAnOngoingConcurrencyStormWithoutMoreStarts in the existing AgentBlameModelTests.swift file, covering finish-only updates, a shared start/finish deadline, quiet precedence and no reports after termination. Verification:.
• Confidence: 96%

Stop counting captured children when they exit (eve-bot-lovinka)

• Context: The deferred meter completion tracked the lifetime of runCapturing(), including afterStart and pipe draining after child exit, inflating concurrent-running counts and potentially reporting a false storm.
• Commit(s): c04a9a81c
• Verdict: accepted
• Code before:

  terminationHandler = { _ in exited.signal() }
  try run()
  let ended = SpawnMeter.started(executable: executableURL, arguments: arguments ?? [])
  defer { ended() }

• Code after:

  let ended = meterStarted(executableURL, arguments ?? [])
  terminationHandler = { _ in
      ended()
      exited.signal()
  }
  do { try run() } catch {
      ended(); throw error
  }

• How was this fixed: Meter registration occurs before launch; successful completion runs in the termination handler before signalling the exit semaphore. A launch failure balances registration in the catch path. The public API is unchanged; an internal overload accepts the meter callback for direct lifecycle assertions. Extended the existing ToolsBridgeTests.swift file outside the original PR diff because it already imports GenesisKitBase with @testable. Added testCapturedChildEndsBeforeAfterStartReturns and testCapturedChildLaunchFailureBalancesMeterRegistration, covering exit while afterStart remains active, registration before launch, failure balancing and no duplicate completion. Verification:.
• Confidence: 95%

Retain helper process tags in displayed and batched perf events (eve-bot-lovinka)

• Context: Classification stripped the helper tag and discarded it. Parent and helper events from the shared Genesis perf log therefore displayed identically, and their ongoing storm events could collapse together.
• Commit(s): c04a9a81c
• Verdict: accepted
• Code before:

  const body = line
      .replace(timePattern, "")
      .replace(/^\[[a-z-]+\]\s+/, "")
      .replace(/^mark\s+/, "");
  const short = (text: string) => text.replace(/ recent=\[.*$/, "").slice(0, 300);

• Code after:

  const message = line.replace(timePattern, "");
  const tag = message.match(/^(\[[a-z-]+\])\s+/)?.[1] ?? "";
  const body = message.replace(/^\[[a-z-]+\]\s+/, "").replace(/^mark\s+/, "");
  const short = (text: string) => `${tag ? `${tag} ` : ""}${text.replace(/ recent=\[.*$/, "")}`.slice(0, 300);

• How was this fixed: Extracted the tag before normalizing the body and preserved it in every classified perf event's text. Ongoing storm keys include both the log directory and process tag, preventing parent/helper collapse within the shared log. Extended dev-monitor.test.ts to compare otherwise identical tagged and untagged storm, spin and stall events, assert the hang event retains its tag, and exercise parent/helper storm attribution through both tails and EventBatcher. Verification:.
• Confidence: 97%

⚠️ Potential issue

Include older running children in concurrency-storm command counts

A storm triggered by the running-child threshold initializes its command counts only from the last 10 seconds of starts, even though running includes older children. For example, start 15 long-lived GenesisTools agents blame children at t=0, then one git status at t=20: the resulting storm reports 16 running but identifies only git status ×1, omitting all 15 processes responsible for the concurrency. Subsequent reports never recover those labels. Track active children by label (and pass the label or an identity into finish), so concurrency-triggered storms can identify the commonest running command rather than only recent arrivals. Add a test with children whose lifetimes exceed the rolling window; the current concurrency test checks only the running count.

🧩 Analysis

Grep evidence: starts\.reduce|starts\.removeAll|running >= Self\.burstRunning

[genesiscz]

Accepted. The follow-up will include older running children in concurrency-storm command counts. The pull request was merged after its fix rounds, so this finding waits for a follow-up, and this thread stays open until then.
