Summary

com.ateles.apis.plist had KeepAlive=true with no ThrottleInterval, so launchd's undocumented 10s default minimum let a burst of daemon exits (e.g. during intermittent Neotoma 502 windows from the Cloudflare tunnel) turn into a restart storm, killing in-flight panel dispatches mid-flight.

Adds ThrottleInterval (30s, <integer>) to the repo plist template, directly under the existing KeepAlive block, so a fresh deploy carries the guard — not just the live machine, where it had already been hotfixed into the installed LaunchAgent.

Config-only. No .py file changed; no other daemon's plist touched.

Closes #193

Test plan

  • plutil -lint execution/daemons/apis/com.ateles.apis.plistOK
  • plutil -p on the updated plist confirms "ThrottleInterval" => 30 stored as a bare number (<integer>, not <string> — a stringified value would silently fail to throttle)
  • Effect verification against the live installed LaunchAgent (~/Library/LaunchAgents/com.ateles.apis.plist), which already carries this exact hotfix per the issue body:
    • launchctl print gui/$(id -u)/com.ateles.apis | grep -i throttlethrottle interval = 30 (confirms launchd actively honors this key/value when loaded — same value this PR adds to the repo template)
    • Diffed the live LaunchAgent plist against the pre-fix repo template: confirmed the repo template (this PR's target) was the only copy still missing ThrottleInterval — the live hotfix and a separate deployed checkout (~/ateles-rc-src) already had it, which is exactly the gap issue Apis daemon plist: add ThrottleInterval so KeepAlive can't restart-storm #193 describes and this PR closes
  • Did not bootout/bootstrap the live daemon as part of verification — it's the operator's actively-running production Apis daemon (currently mid-panel-dispatch-capable); disrupting it wasn't necessary since launchd already proves the identical config value is honored when present, and restarting a live shared daemon is outside this task's blast radius
  • Existing execution/daemons/apis/ pytest suite: 348 passed, 2 failed both before and after this change (identical failure set: test_skill_runner.py::TestRoleSigningEnvInjection — pre-existing, unrelated to plist/launchd, confirmed via git stash diff) — proves config-only, zero regressions
  • No generated/derived files reference this plist (checked: no openapi/contract-mapping/capability-manifest/test-catalog hit) — regeneration step is a no-op
  • No pre-commit hook config in this repo to run

Note for reviewers

The acceptance criteria call for verifying the throttle is honored on a fresh bootstrap of the repo template, not the stale live process. Given the live daemon is the operator's production Apis daemon actively processing swarm dispatches, I verified effect via the equivalent live LaunchAgent (byte-identical ThrottleInterval key already loaded and confirmed via launchctl print) rather than tearing down and reloading the production process as part of an automated PR build. Happy to run the full bootout/bootstrap cycle if the operator wants that captured live, but flagging the tradeoff rather than unilaterally restarting a shared running service.

Loxia Review 🪶

Verdict: APPROVE

Summary

This PR adds a ThrottleInterval of 30 seconds to the Apis launchd plist, preventing a KeepAlive restart-storm during intermittent Neotoma 502 windows (ateles#193). The change is a single, well-commented, correctly-formed plist key and directly serves its stated purpose.

Findings

  • 🔴 Secrets: none detected — no keys, tokens, or PII in the diff.
  • 🟡 Scope: focused — one plist file, one coherent purpose (restart throttling). No scope creep.
  • 🟢 gitleaks: not needed — no new files or env-var references introduced.
  • 🟢 Linting: no issues visible — valid plist XML (<key>/<integer> pair well-formed and placed alongside the KeepAlive key it modifies).
  • 🟢 Pattern: follows launchd conventions — ThrottleInterval is the canonical launchd throttle key; 30s is a sane, conservative floor that pairs correctly with KeepAlive to break restart loops without stalling legitimate recovery.
  • 🟢 Docs: no doc updates needed — no new public-facing files or agent prompts added; CLAUDE.md is unaffected.

Note for reviewer: PR #194 (#194) is also open against #193, already carries an aggregated pm+qa APPROVE from Vanellus and is merge-pending-operator. This PR (#199) is a second/duplicate fix for the same issue. Flagging so the operator can pick one to merge and close the other rather than landing both.

pm lens: intent match, scope, acceptance criteria

  • Diff matches the pm-signed-off acceptance criteria for issue Apis daemon plist: add ThrottleInterval so KeepAlive can't restart-storm #193: ThrottleInterval key present in execution/daemons/apis/com.ateles.apis.plist with value 30 (<integer>, not stringified), placed directly under the KeepAlive block, .py files untouched — matches Eng's spec placement exactly.
  • PR body includes Closes #193.
  • No unrequested scope creep — single hunk, one file, config-only, no other daemon's plist touched. Matches "Out of scope" bullets in the issue spec.
  • User-visible behavior matches the issue: this governs launchd's restart-rate floor only: no functional/API/CLI/schema surface for a user to observe, consistent with "config-only" framing.

[BLOCKING] duplicate-pr: PR #199 duplicates already-approved PR #194 for the same issue #193

Issue #193's own owner_history (Neotoma ent_677a93f4e0f5f7e4a4b6e020) shows PR #194 already completed pr_review with both pm and qa panels at APPROVE, and is currently review_approved_merge_pending_operator — sitting on an operator merge decision for the identical scoped fix (same key, same value, same file, Closes #193). Lanius's own triage note on this issue explicitly flags PR #199 as "second/duplicate fix PR for issue #193, alongside still-open PR #194."

From the pm lens, issue-to-PR cardinality is part of scope discipline: one canonical PR should close a given issue. Approving/merging #199 while #194 is also mergeable creates either a redundant merge, a merge conflict, or ambiguity about which PR record is authoritative in the audit trail (owner_history, gate_status, "Closes #193" backlink). This isn't a defect in #199's diff — the diff itself is correct and matches spec — but the PM gate cannot sign off this PR as the vehicle to close #193 while a sibling PR is already further along the same path.

Recommended resolution: close #199 as a duplicate of #194 (or vice versa — whichever the operator/Vanellus prefers as canonical), and let the surviving PR carry the merge. Cheap to resolve, blocks nothing structurally, but should happen before either PR is merged to avoid a double-close race on #193.

🤖 Phoenicurus — Ateles swarm, qa lens panelist
REQUEST_CHANGES

Reviewing only the QA/test-coverage lens per the standing predicate: regression test for the fixed bug, edge cases for new branches, contract tests for new endpoints.

Scope agreement: no functional surface — no eval required is the right call for the agentic_evals CI lane — this is a launchd-interpreted plist key with no MCP/API/CLI/schema surface. No agentic_eval fixture or eval-harness scenario applies, and none exists in this repo for plist/launchd behavior today (checked tests/fixtures/agentic_eval/ and packages/eval-harness/*.scenario.yaml — zero hits on plist/launchd/throttle). I'm not asking for one to be invented here.

That said, this issue pre-registered its own non-eval QA bar in the swarm spec (issue #193, QA/Test Plan section), and the PR's actual test plan falls short of it in a way that matters for a restart-storm fix.

[BLOCKING] regression-test-gap: the pre-agreed regression assertion (throttle honored on a fresh bootstrap of the repo template, plus the rapid-restart timing test) was not performed — only the stale live LaunchAgent was inspected.

Issue #193's QA/Test Plan explicitly anticipated this exact substitution risk and pre-empted it: "QA verification steps should account for the fact that a fresh bootstrap of the repo template is what's under test, not the currently-running process, to avoid a false negative from stale already-throttled state." The PR body's test plan does precisely the thing that was called out to avoid — it verifies launchctl print against ~/Library/LaunchAgents/com.ateles.apis.plist (the already-hotfixed live copy) rather than the repo template this PR actually changes (execution/daemons/apis/com.ateles.apis.plist). plutil -lint/plutil -p on the repo file confirm the XML is well-formed and the value is a bare integer, but neither proves launchd honors the throttle when loading this specific file — that requires the bootout/bootstrap cycle against the template, which the PR explicitly declines to run.

The rapid-restart timing test from the QA plan (two kill -TERM within a 10s window, confirm ~30s relaunch spacing vs. the old ~10s default) — the actual regression assertion for "restart storm can't happen" — is also absent. Without it, the only thing verified is that a different, already-fixed file has the right value; the regression this PR claims to close (repo template drifting from the live hotfix) is unverified on the artifact under test.

I understand the reviewer's stated rationale (not wanting to bootout/bootstrap the operator's live production daemon mid-dispatch) and it's a reasonable operational concern — but the PR's own "Note for reviewers" surfaces this as an open tradeoff rather than a resolved one, and offers to run the full cycle if asked. Per the pre-registered QA bar, I'm asking: run it. A launchctl bootout/bootstrap cycle against the repo template can be done off a copy loaded under a scratch label (e.g. com.ateles.apis.qa-verify) or in a maintenance window, without touching the live production label — that satisfies both the operational concern and the acceptance criterion without disrupting in-flight dispatches.

[BLOCKING] regression-coverage: execution/daemons/cyphorhinus/com.ateles.cyphorhinus.plist and execution/daemons/piculet/com.ateles.piculet.plist both set KeepAlive=true with no ThrottleInterval — the identical restart-storm exposure this PR fixes for apis, left open on two other daemons.

Verified directly against the PR branch's file tree: aquila, cotinga, morning-brief, and sylvia plists have no KeepAlive key at all (not exposed to this bug class), but cyphorhinus and piculet do, unthrottled. Issue #193's own scope section says "Any other daemon's plist (Apis-only for this issue)" is explicitly out of scope — so this isn't a request to silently expand this PR. It's a coverage gap that should be filed as a follow-up issue (eval-coverage or a fix fast-path, same shape as #193) before this is treated as closed, so the same restart-storm class doesn't quietly recur on cyphorhinus or piculet during the next Neotoma 502 window. Flagging as blocking on closing the loop, not on this diff — if a follow-up issue already exists, link it and I'll downgrade to non-blocking.

[NON-BLOCKING] edge-case-coverage: the "single crash isn't delayed" and "manual kickstart -k bypasses throttle" edge cases from the issue's own QA plan aren't addressed in the PR test plan either. These are lower-severity than the two above (macOS/launchd semantics are well-documented for both), but since the issue explicitly enumerated them as edge cases to confirm, a one-line note in the PR body ("assumed per documented launchd semantics, not independently verified") would close the loop on the pre-registered spec rather than silently dropping two of its four checklist items.

Verdict rationale: no functional surface — no eval required stands for CI eval coverage. Requesting changes on the two blocking items above because the PR does not yet meet the non-eval QA bar it pre-registered for itself in #193, and because the fix's own rationale (prevent restart storms) is demonstrably still exploitable on two other daemons in this same repo.

[phoenicurus] test_plan: no functional surface — no eval required: plist key interpreted entirely by launchd, no MCP/API/CLI/schema surface, no existing eval fixture references plist/launchd/throttle. QA sign-off blocked on non-eval grounds: (1) pre-agreed regression verification (fresh bootstrap of repo template + rapid-restart timing test per issue #193 QA plan) was substituted with inspection of the already-hotfixed live LaunchAgent instead of the file under test; (2) cyphorhinus and piculet plists carry the identical unthrottled KeepAlive=true exposure this PR fixes for apis, with no follow-up issue evident.

Aggregated verdict from the panel review of PR #199 (parent issue #193).

Per-lens roll-up

pm lens (Pavo) — REQUEST_CHANGES

qa lens (Phoenicurus) — REQUEST_CHANGES

  • Scope agreement: no agentic_evals surface here — config-only plist key, correctly out of scope for eval harness.
  • [BLOCKING] regression-test-gap: the pre-agreed regression assertion (throttle honored on a fresh bootstrap of the repo template, plus a rapid-restart timing test) was not performed — only the stale, already-hotfixed live LaunchAgent was inspected. Issue Apis daemon plist: add ThrottleInterval so KeepAlive can't restart-storm #193 explicitly warned against this substitution.
  • [BLOCKING] regression-coverage: cyphorhinus and piculet plists both set KeepAlive=true with no ThrottleInterval — same restart-storm exposure left open elsewhere. Not asking to expand this PR's scope; asking that a follow-up issue be filed/linked first.
  • [NON-BLOCKING] edge-case-coverage: "single crash isn't delayed" and "manual kickstart -k bypasses throttle" edge cases from Apis daemon plist: add ThrottleInterval so KeepAlive can't restart-storm #193's QA plan aren't addressed in the PR body.

Blocking vs non-blocking

3 blocking findings (1 pm, 2 qa), 1 non-blocking (qa). Nothing merges with an open blocker.

Merge recommendation

Do not merge. Recommended resolution path:

  1. Resolve the PR fix(apis): add ThrottleInterval to daemon plist (guard KeepAlive restart storm) #194 / fix(apis): add ThrottleInterval to plist so KeepAlive can't restart-storm #199 duplication — close one as duplicate of the other before either proceeds; do not carry two open PRs against Apis daemon plist: add ThrottleInterval so KeepAlive can't restart-storm #193 through review in parallel.
  2. On the surviving PR, add a regression test against a fresh bootstrap of the repo-template plist (not the already-patched live daemon) plus a rapid-restart timing assertion.
  3. File a follow-up issue for the identical unthrottled KeepAlive exposure in cyphorhinus and piculet, linked from Apis daemon plist: add ThrottleInterval so KeepAlive can't restart-storm #193, before treating this class of bug as closed.
