 - `task.list` defaults to a compact, 20-item active/paused projection; bounded closed/all history is opt-in with `status` and `limit`, and `task.inspect` defaults to `summary`. Closed views evaluate their captured closure candidate and carry no current writer lease.
 - Workit tracking is optional: direct investigation, questions, non-Git work, and routine reversible edits need no task, policy assessment, or writer calls. Start one compact task only when handoff, dependencies, concurrent actors, or meaningful decisions make continuity useful; assess or reassess when the relevant rules/evidence require it. `policy.preview` stays read-only.
 - Routine authorized branch/commit work chooses native host Git/shell tools from the outset when managed coordination or reconciliation is unnecessary. Resolve target conventions; never switch paths after a denial or uncertain managed effect to evade safeguards. A local-commit endpoint creates no PR-readiness or task-closure ceremony. The distributed bootstrap carries this routing guidance.
