fix(tasks): single-line titles and single-token assignees on write (TASK-354) - #2483
lilyshen0722 wants to merge 3 commits into
Conversation
…ASK-354) Newlines in a title collapse to a space, and a title that is blank after that is refused. Assignee is trimmed; an inner space or control character is refused and case is kept. Applied to both create and PATCH.

Preserve idempotency for existing multiline titles.
If an existing task has sourceRef and a title such as Fix\nboard, a replay with the same input now looks up Fix board. The lookup at Line 284 misses the existing task, and the (sourceRef, title) index permits a second task. Add a compatibility lookup or migrate existing titles before changing this identity key. Cover a replay against a previously stored multiline title.

…-354) Title: any run of whitespace, newlines included, collapses to one space, and a title blank after that is refused. Assignee: one handle, trimmed, case kept; an inner space or any C0, DEL or C1 control character gets a 400 that asks for a handle. The rules live in utils/taskFieldNormalization and apply to the tasks API (POST and PATCH) and the native runtime's create tool. The board's assignee placeholder now asks for a handle.

Head: 4c0d225
HOLD — backend/services/nativeRuntimeService.ts:290 still describes commonly_create_task.assignee as “Optional assignee display name”. The new dispatch validation at :866 rejects multiword display names with invalid_assignee. A native agent following its offered tool schema can now fail to create a task. Change that schema description to require a single handle, and pin the offered contract in a test.
The focused route and native suites pass (52/52). Reverting POST title normalization makes two paired assertions fail; bypassing the POST assignee refusal makes three fail. CI is green at this head. I did not measure rendered layout.

GATE: HOLD
The native tool's assignee description said display name, so an agent following its own contract now hits the 400. It now asks for the handle (agentName or instanceId, one token). Tests pin that a handle is stored and a multiword name is refused before any row is written.

Resolve instanceId assignees before task-completion dispatch.
The completion route passes the stored assignee to recordTaskCompleted. That consumer accepts only an agentName match. An instanceId such as default can fail the membership check and skip the system exchange. Resolve instanceId values in the consumer, or remove them from the advertised assignee contract.
