Two P0 fixes from ISSUE #413 — both address workflow await_approval
approvals that silently failed in production:
B1 — AwaitApprovalStepAdapter now dispatches the approval notice to
every channel in approverChannels that carries a target. Previously
approverChannels was write-only metadata: a workflow that declared
["feishu:oc_xxx"] silently dropped the notice and the IM group never
learned an approval was waiting. Element format is "channelType"
(no push, operator uses admin console) or "channelType:targetId".
Each channel failure is logged and skipped — it must not fail the step.
B2 — requestWorkflowApproval now registers the wf- approval into the
in-memory map via registerRecovered. Previously it only did
approvalMapper.insert, so getPending("wf-...") returned null,
performResolve short-circuited at the not-pending guard, the
WorkflowApprovalResolvedEvent was never published, and
ApprovalResumeBridge was dead code. With this fix, resolving a wf-
approval walks the full two-phase contract and the bridge fires.
Tests:
- WorkflowApprovalResumeBridgeTest (3): map registration, event
publish on resolve, safe no-op for unregistered wf- ids.
- AwaitApprovalNotifyTest (2): targeted channels dispatched, bare
"web" skipped, channel failure non-fatal.
Regression: ApprovalWorkflowServiceResolveTest (13), AwaitApprovalRuntimeTest (3),
DispatchChannelRuntimeTest (3), GcTest (7), RecoveryTest (7) — all green.
