Task-shaped typing is explicit intent

Context

ADR 0031 forbids implicit promotion so imported Markdown and ordinary checklists cannot silently fill the workspace task index. A compound editor gesture can nevertheless express intent more precisely than portable Markdown: the user first opens a bullet item, then types a complete checkbox marker.

Decision

Typing - , * , or + followed by [] , [ ] , [x] , or [X] in a fresh top-level bullet item explicitly creates a linked task. The editor assigns fresh task and block identities immediately; durable promotion remains deferred to the normal save debounce and requires a non-empty title.

Document shape alone is never intent. Imported, pasted, or parsed - [ ] Markdown remains an unlinked checkbox unless it carries Skriuw's private task marker. Continuing a non-empty task with Enter creates a new task with new identities. Empty linked items serialize without a marker and are never promoted.

Consequences

The editor keeps the same portable Markdown presentation for tasks and checkboxes while preserving the source link required by ADR 0031. No typing gesture performs IPC or storage work, so the editing performance contract stays intact.
