Summary

Issue #354 (claude-code adapter: no auto-resume after async A2A delegations) is already resolved by fix #376 (logA2ADelegationResult wires proxy-path delegation results into activity_logs). This PR adds a docstring explaining the fix chain.

The root cause: When Design Director fires 6 parallel delegate_task calls, the claude-code subprocess times out before all results return. The proxy-path responses were stored with method='a2a_receive', invisible to the heartbeat delegation-polling path.

The fix (already merged as #483): logA2ADelegationResult writes method='delegate_result' rows, which ListDelegations serves and _check_delegations polls. On the next heartbeat tick the agent receives a self-message with the results and synthesizes a user-facing reply.

This PR: +8 lines documenting the relationship in heartbeat.py's module docstring.

Test plan

pytest tests/test_heartbeat.py — 26/26 pass
Full Python suite — same pre-existing failure count as HEAD

Issue #354 (claude-code adapter: no auto-resume after async A2A
delegations) is resolved by fix #376 (logA2ADelegationResult wires
proxy-path delegation results into activity_logs). This docstring
update explains the fix chain so future readers understand why
_check_delegations sends a self-message when results arrive.

Five-Axis review — APPROVE (accurate docstring; trivial, zero-risk)

+8/-0, one file (workspace/heartbeat.py) — adds a docstring paragraph to the module header documenting the #354 fix chain: when N parallel delegate_task calls exceed the per-turn timeout the claude-code subprocess exits before results arrive; the proxy-path results are now stored with method='delegate_result' (fix #376 / a2a_proxy_helpers.go:logA2ADelegationResult, merged as #483), so _check_delegations finds them on the next heartbeat tick and self-messages the agent to wake it with the results.

1. Correctness ✅ — the description matches the merged state: #483 (`fix(#376): store proxy-path delegation results in activity_logs`) is merged, and it's the mechanism that makes proxy-path delegation results visible to the heartbeat polling loop (previously stored with the heartbeat-invisible `method='a2a_receive'`). The "self-message to wake the agent" matches `heartbeat.py`'s existing "store completed delegation results for the agent to pick up" behavior. Accurate.

2/3/4. Tests / Security / Operational — N/A (docstring only; no code path changed).

5. Documentation ✅ — this is the point of the PR; it puts the "why does the heartbeat poll for delegations / how does #354 get resolved" knowledge where a reader of `heartbeat.py` will find it, instead of only in the #354/#376/#483 PR threads. Good.

Non-blocking note

base=staging — should target main per internal#81; #325 carries it. Flag for next round, not a blocker for an 8-line docstring.

Fit / SOP

✅ Closes the documentation half of #354 (the code half is already done via #483) — the right move when an issue is "fixed but undocumented".
✅ OSS-shape: minimal, in the right place, correctly scoped.

LGTM — approving. (Advisory — hongming-pc2 ∈ Owners only, not the approval whitelist per internal#318; needs a core-qa/core-lead/engineers-persona APPROVE for the merge gate. This review is the substance. Suggest #354 be closed once this + #483 are both on the same branch.)
