automation: a save_notice after a subflow or map whose child suspends passes publish and strands every decision of the parent run #28840
Description
domain:server#3 · os-project-manager · session_01FEkQ5kE5BrPUPNMMyv6oCH
Blocked-by: PR #28838
Filing gate: ① should-fix of the CONTRACT_REVIEW_TIER review 6565504502 on PR #28838 (#28806). Measured by that PR's rewritten round-trip test (packages/plugins/plugin-approvals/src/save-notice-approval-round-trip.integration.test.ts). Filed by domain:server seat 3. ⛔ Not a claim.
Reach: after PR #28838, the placement door refuses a save_notice reachable from an approval, wait or screen node in the same graph. It cannot see a suspension inside a child flow. start → save_notice → subflow(child with an approval) → save_notice still parses. At run time:
- the parent suspends at the
subflownode; - the decision resumes the child, and
bubbleToParentresumes the parent from the store; - the parent's second
save_noticerefuses by name; - the parent lands on the stranded exit, and
decideanswers 200 withresumed: trueandresumeFailure: RESUME_FAILED.
So every decision strands the parent run. A map whose item flow suspends has the same shape. The parse cannot refuse by node type: FLOW_PAUSE_CAPABLE_NODE_TYPES leaves out subflow and map by ruling D, and start → subflow(synchronous child) → save_notice runs correctly today.
Wanted
The author learns before the first decision that a save_notice reachable after a subflow or map whose child can suspend never answers a write.
Direction: refuse it where the child flow is in hand. That is the existing registerFlow / activation door, where subflow-guards.ts already resolves subflowTargets. Reuse the #28806 sentence shape and name the subflow / map node and the child's suspending node. ⛔ No new gate: extend that door, or state why it cannot carry this. ⛔ Do not change FLOW_PAUSE_CAPABLE_NODE_TYPES (ruling D), the stranded-decision posture or RESUME_FAILED.
This narrows activation: a flow set that registers today is refused. So it is Clause-②: no (narrowing), with a CONTRACT_REVIEW_TIER review owed. The dev measures shipped flows (showcase, dogfood, hotcrm) for the shape. None is expected.
Dedupe
Read open issues for save_notice subflow, subflow approval strand and resumeFailure: #28806 (the same-graph half, PR #28838) and objectstack-ai/hotcrm#2398 (HotCRM places save_notice before its approval). New.
Reader who acts: domain:server (packages/services/service-automation registration guards, or packages/lint only if no registration door sees the child).

Refuse at registerFlow when the child is held, and make the boot pull and re-syncs register children before callers (topological by subflowTargets).
