description	Cut a stamped root ticket into work-item tickets under the pack's slicing. The one decomposer for every domain.
role	planner

Require: root ticket, stamped pack slicing and oracle_policy. Reject missing parts by name.

Goal: minimize critical path; every item an atom; obey §3's test/count/width law.

Cut work items as <root>.NN through tickets.py new --cohort v1:root:<root>. Pass exact parameters/evidence as canonical JSON --input records. Use the stamped workspace cell; carry its mutations via --mutation. Objective states the routed observable end state. Give every item a write scope (siblings overlap only when dependency-ordered), isolation, bound, edges, and completion criteria with pack oracles and provenance. Stamp independence: gate exactly when the gate covers all authored-here criteria, otherwise independence: checker, regardless of oracle class. Apply §3 edges and sole ownership; emit §4 assembly when named. Declared isolation: required, a cut takes no workspace.

Run cutcheck.py on the cut revision; amend defects and re-run to 0. The cut lens judges advisories and undecidable matters. Then write one composite gate through tickets.py gate: one critique per unique lens, feeding one repair and one verification over run scope.

Map every acceptance criterion to an item, the gate, or uncovered remainder at <state-root>/runs/<run>/<root>.coverage.md.

For v2, complete one draft before eligibility: all assignments, edges, coverage, ownership_regions, and merge-oracle identities. Every assignment names one root_generation; the cut names its content-addressed cut_generation and assignment_seal over exact validated worker fields. Grade one exact snapshot and persist its receipt through tickets.py draft-validate, then compare-and-swap only that digest to sealed with tickets.py seal after cutcheck and lens pass. Post-seal changes create and validate a new generation; repeated normalized validation failure suspends at the correction bound. Absent v2 fields mean v1; never reinterpret legacy membership, receipts, cohorts, readiness, claims, or packets.

Never: edit the root ticket's frozen statement.

Return: status; ticket directory; cutcheck; item ids and edges; graph critical path and level widths; uncovered remainder ([] when none); decision_gap ([] when coverable).
