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. The poorMode settings mock mirrors unrelated real settings defaults to avoid Bun mock retention changing later permission tests.
Constraint: PR #369 must fix Codecov/CI precisely without warning suppression, fallback masking, or mock pollution
Rejected: Delete AgentSummary lifecycle coverage | would hide Codecov loss and stale-summary behavior
Rejected: Store inline UDS rejection in a hidden input sentinel | cloned observable inputs can drop it and bypass rejection
Rejected: Ignore malformed UDS frames until timeout | leaves client slots and SendMessage calls open to exhaustion
Confidence: high
Scope-risk: moderate
Directive: Keep empty #token= markers rejected; do not require a non-empty token value in hasInlineUdsToken

CodeRabbit and Codecov surfaced real gaps in UDS framing, peer discovery, mailbox retention, and summary context coverage. 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
