feat(daemon): surface a2a-inbox arrivals in real time - #179
Conversation
…8761_23739797) Step 7.5d's 4h heartbeat cadence is the only consumer of a2a-inbox today, which sat blind for hours across two prior incidents (08-17, 08-30). Adds a fail-quiet FastChecker poll: opt-in per instance via AgentConfig.a2a_inbox_owner (defaults unset/false, preserving current behavior everywhere), arrival-only (never moves/mutates a2a-inbox files — that stays the agent's own Step 7.5d job), with a persisted already-notified filename set so a poll-based watch doesn't re-notify the same unprocessed file every cycle. Notified-state is only persisted after a confirmed PTY injection, mirroring the existing inbox ackIds pattern so a failed injection retries next poll instead of dropping the arrival. Design approved by boss 2026-08-31 (both open decisions: explicit config field over HEARTBEAT.md text-sniffing, poll+notified-set over chokidar).

Fleet peer review (murph). Cloned and reviewed independently rather than trusting the description alone. Verified: Security check (this is externally-influenced content going into a PTY injection, so worth a close look): Design check: confirmed the arrival-only claim — Two non-blocking observations:
LGTM — real, well-tested, fail-quiet by construction. Formal approval blocked (shared identity, same as every other fleet self-review). |
Per murph's PR #179 review — the entry was missing.

while processing configurations that set a2aInboxOwner from
config.a2a_inbox_owner, reject multiple enabled owners before constructing any
FastChecker instances, and add a test covering two configured owners.

- Around line 456-457: Update the safeName and safeKind handling in the A2A
message injection flow to normalize sender.name and kind to single-line values
before interpolating them into the header, preventing newline-based header or
instruction injection; add regression coverage for newline-bearing sender.name
and kind while preserving the existing wrapFenceSafe payload behavior.

In `@CHANGELOG.md`:
- Around line 15-16: Update the CHANGELOG entry describing
AgentConfig.a2a_inbox_owner to document that it is an independent per-agent
opt-in; multiple enabled agents may inject duplicate notifications because state
is tracked per agent, so deployments should configure a single owner.

Two CodeRabbit findings from PR #179's review: 1. AgentManager.claimA2AInboxOwner() enforces exactly-one-owner-per-instance for AgentConfig.a2a_inbox_owner, refusing (loudly) a second agent's claim instead of letting both poll the same a2a-inbox and both inject duplicate notifications. Restarting the current owner is not a conflict (stopAgent releases the claim first). 2. formatA2AMessage forces sender.name/kind to a single line before interpolating them into the header. sanitizeForPtyInjection alone only neutralizes the two header strings it already knows about (AGENT MESSAGE, TELEGRAM) — an embedded newline followed by a forged "=== A2A MESSAGE from ... ===" header (a string the shared sanitizer has no entry for) would have passed through unrecognized. 6 new tests (agent-manager: 5, fast-checker: 1). Full suite green.

Summary
AgentConfig.a2a_inbox_owner(absent/false everywhere by default, current behavior fully preserved). Arrival-only — never moves/mutates a2a-inbox files, that stays the owning agent's existing Step 7.5d processing.state/<agent>/.a2a-notified.json), only written after a confirmed PTY injection — mirrors the existing inboxackIdspattern so a failed injection retries the same arrival next poll instead of silently dropping it.Design was scoped and approved by boss on 2026-08-31 (deliverable:
