The tests exercise AgentSummary lifecycle branches, mailbox fail-closed behavior, UDS client connection failure through a real capability file, and UDS response-reader framing without mock.module, warning suppression, feature fallback, or production-code churn. Constraint: PR #369 is already merged; this branch must contain only the incremental Codecov repair on top of latest main Rejected: Reopen or keep pushing the merged PR branch | merged PR refs do not update and would leave Codecov stale Rejected: Mock bun:bundle or hide warnings | would reintroduce cross-test pollution and pseudo coverage Rejected: Keep unrelated SendMessageTool production diff | it created avoidable patch-coverage debt without improving the runtime path Confidence: high Scope-risk: narrow Directive: Keep these coverage tests on real paths; do not replace them with output suppression or feature-flag mocks Tested: bunx tsc --noEmit --pretty false Tested: bun run lint Tested: bun test src\utils\__tests__\teammateMailbox.test.ts Tested: bun test src\services\AgentSummary\__tests__\agentSummary.test.ts src\services\AgentSummary\__tests__\summaryContext.test.ts src\utils\__tests__\teammateMailbox.test.ts src\utils\__tests__\udsMessaging.test.ts src\utils\__tests__\udsResponseReader.test.ts packages\builtin-tools\src\tools\SendMessageTool\__tests__\udsRecipientSanitization.test.ts Tested: bun run test:all Tested: bun test --coverage --coverage-reporter lcov --coverage-dir coverage Tested: bun run build Tested: bun run build:vite Tested: bun audit Tested: git diff --check Tested: Claude simplify review GO (.omx/artifacts/claude-simplify-codecov-20260427-1521.md) Tested: Claude security review GO (.omx/artifacts/claude-security-codecov-20260427-1522.md) Not-tested: GitHub-hosted Codecov upload after this amended commit until PR checks rerun * test: keep review assertions tied to real failure paths CodeRabbit flagged three non-blocking but valid review gaps: platform-specific mailbox errno checks, brittle UDS connection-failure message assertions, and missing AgentSummary reschedule proof after fork errors. This keeps the fixes narrow by tightening the affected assertions and adding a structured UDS connection error for tests to assert behavior instead of prose. Constraint: PR #374 is a review follow-up and must not hide warnings, skip tests, or merge the PR. Rejected: Matching the UDS failure message literal | preserves the brittle coupling CodeRabbit flagged. Rejected: Asserting only that mailbox writes throw | would allow unrelated pre-path failures to pass. Confidence: high Scope-risk: narrow Directive: Keep UDS connection-failure tests on structured error data, not display wording.

This keeps the production behavior unchanged: timers still schedule the summarizer closure, tests now assert timer-handle identity, and UDS connection errors use native Error.cause instead of shadowing it. Constraint: Do not manufacture behavior just to satisfy a review hint; assertions must match the real AgentSummary scheduling contract. Rejected: Assert a fresh scheduled callback function | scheduleNext intentionally passes the same runSummary closure each time. Rejected: Store a custom cause field on UdsPeerConnectionError | native Error.cause is available under ESNext/Bun. Confidence: high Scope-risk: narrow Directive: Timer tests should assert returned handle identity for ownership, not incidental numeric values.

Timeouts now use the same structured peer failure contract, and the test exercises that path through a short explicit timeout instead of waiting for the production default. The AgentSummary unchanged-fingerprint test now also asserts that the second unchanged tick does not log errors, preserving the existing behavior checks without changing production scheduling semantics. Constraint: Keep the production timeout default at 5000ms while allowing tests to exercise the timeout path quickly. Rejected: Leave timeout failures as generic Error | callers would need separate handling for the same peer connection failure class. Confidence: high Scope-risk: narrow Directive: Keep UDS send timeout and socket-error branches on the same structured error contract.

Dosion	52b61c2c06	fix: bound agent communication memory growth (#369) ... * fix: bound agent communication memory growth UDS messaging now uses private local capabilities instead of exposing auth tokens through SDK metadata, environment variables, session registry, peer listing, or tool output. The receive path bounds NDJSON frames, response buffers, active clients, and pending inbox bytes, and strips auth metadata before messages enter the prompt queue. Teammate mailboxes now validate file and message sizes, fail closed on corrupt mutation inputs, compact by count and retained bytes, and use stable message identity for in-process acknowledgements. Agent summaries now fork only a bounded recent context using lazy size estimation and content fingerprints instead of retaining or serializing unbounded histories. Constraint: PR #361 was already merged; this branch is based on upstream/main@c2ac9a74. Rejected: Default-disabling COORDINATOR_MODE/TEAMMEM only | explicit feature enablement still hit unbounded paths. Rejected: Persisting UDS auth in SDK/env/session registry | bridge/remote metadata can leak local capability secrets. Rejected: Inline uds #token addresses | observable/tool/classifier paths can reflect raw addresses outside the UDS request frame. Rejected: Positional mailbox marking after compaction | compaction can shift indices across the lock boundary. Confidence: high Scope-risk: moderate Directive: Do not expose UDS capability tokens through SDK messages, environment variables, session registry, peer-list output, or SendMessage result/classifier surfaces. Directive: Do not reintroduce positional mailbox acknowledgements unless compaction is removed or read+mark is atomic under one lock.

This tightens those paths without suppressing review or coverage signals. Constraint: PR #369 must address CodeRabbit and Codecov findings without warning suppression or fake fallbacks Rejected: Suppress Codecov or CodeRabbit warnings | leaves real receive-path and test-isolation gaps Rejected: Add unreachable feature-gated tests | bun:bundle keeps those branches compile-time gated in local tests Confidence: high Scope-risk: moderate Directive: Keep UDS auth-token rejection outside feature flags; do not reintroduce inline token fallbacks Tested: bun test --coverage --coverage-reporter lcov --coverage-dir coverage; bun run test:all; bun run lint; bun run build; bun run build:vite; bun audit; git diff --cached --check Not-tested: Remote Codecov/CodeRabbit refreshed reports until pushed * fix: prevent agent communication bounds from hiding CI regressions Tighten the UDS auth, framing, and response-reader boundaries while keeping the AgentSummary lifecycle covered so Codecov and CI fail on real regressions instead of missing coverage.
