fix(delegation): return delegationSource on every decideNextAgent path (#3346) - #3456
Conversation
Upstream manifest-synced scripts must expose a consistent delegationSource field so consumer sync review threads on agent_delegation_policy.js and keepalive_loop.js can close. Adds regression tests for the shape contract and agent:auto keepalive resolution. Closes #3346 Co-authored-by: Cursor <cursoragent@cursor.com>

📝 WalkthroughWalkthroughThe delegation policy now reports whether each agent-selection result uses static or route-weight delegation. Tests cover explicit, initial, continuing, stalled, and keepalive routing paths. ChangesDelegation source reporting
Priority: ➖ Normal Estimated code review effort: 2 (Simple) | ~10 minutes Change: Bug fix · Severity of issue fixed: Medium Merge Risk: 🔵 Low · up to No-agent keepalive evaluations can omit the delegation-source metadata introduced by this change. This is a narrow reporting issue without evidence of incorrect agent selection, so the risk is low. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- The block beginning here is an exact duplicate of the test at lines 383-416, including the same name, inputs, and assertions. This runs the same regression twice and leaves duplicate test names in the suite; remove the second copy instead of retaining redundant coverage.

loadRouteWeights still calls global fetch even when ROUTE_WEIGHTS_URL points at an unreachable host, so the regression could wait for the 5s timeout. Reject immediately and restore fetch in cleanup. Co-authored-by: Cursor <cursoragent@cursor.com>
