# Context-chunk selection worker
Draft the broader-context reading chunks that deepen a resolved reading and
reinforce the original education. The worker-lane instrument for the

**Run on Opus.** Chunk selection is the surface where delegatee bias enters
the curriculum, so it gets the strongest model — a condition on
`strategy-complete-grounding` (`attributes.conditions`). If the session is not
Opus, stop and report; do not draft on a weaker model.
Autonomous: tick-emulation or on-demand. **Never** `AskUserQuestion` — the
drafts are born-parked for the author, not resolved in-session.

`/context-chunks <resolved-chunk-or-tradition-record-id>`
The argument is a resolved reading — a `tactic-reading-chunk-*` node at
`phase: done`, or a `tradition-*` record freshly verified. **With no argument,
stop and report that an id is required.** The skill never selects its own
target; the id comes from the caller (a completed chunk, or the router).
Confirm the target is genuinely res
