feat(message): publish tips on Message write path - #280
Merged
Conversation
- Add a process-wide host EventBus singleton and $choysum.bus.publish bridge so modules publish to the same bus as TipHub/task. - Publish a thin message.thread.changed tip after successful Message.Post without rolling back on tip failure. Co-authored-by: Cursor <cursoragent@cursor.com>

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR adds best-effort message tip publication and shared bus wiring. The bounded merge-readiness risk is test-state leakage that can make later tests order-dependent; the change is mergeable with explicit owner follow-up to restore patched state and clean up factory registrations.

In `@modules/message/service/models/message.ts`:
- Around line 155-163: Update ensureTipFields so narrow selections always
include CreatedAt, or otherwise make publishThreadChangedTip obtain the original
tip timestamp independently of returnFields; preserve the existing
field-selection behavior while ensuring the event’s at value remains the
publication timestamp. Add a regression test covering Post with fields that omit
CreatedAt.
In `@pkg/bus/host.go`:
- Around line 19-25: Introduce one shared nil-like EventBus check and use it in
SetHost, EnsureHost, applyEvents, and runtimeWithDefaultTaskRuntimeDeps so
typed-nil buses are rejected at every boundary. Update pkg/bus/host.go:19-25 and
internal/server/server_taskruntime_state.go:51-54; add direct regression
coverage in pkg/bus/host_test.go:37-58, server-wiring coverage in
internal/server/server_tiphub_test.go:17-35, and task-runtime coverage for
typed-nil EventBus values.

bus.SetHost before returning it, while preserving EnsureHost for unusable or
absent buses. Add a regression test covering a usable injected EventBus and
verifying it becomes the host.

sections: modules/message/service/tests/message.test.ts lines 656-659 around the
missing-publisher checks and lines 683-690 around the live-publisher check. Save
each section’s prior root.bus value before overwriting it, then restore it after
the assertions, while preserving the existing publish-tip test behavior.

wrap the Date, number, and string CreatedAt cases around Message.Post and
assertions in try/finally, restoring Message.Create in the finally block. Apply

modules/message/service/tests/message.test.ts:751-768, using the existing
origCreate reference.

registration helper to restore an absent prior state: in the branch where ok is
false, delete factories[name] instead of leaving the newly registered factory,
while preserving restoration of old when ok is true.
