Tasks: Tasks Degod Wave 2: Render Seam + Relocation
Mission: tasks-py-degod-wave2-01KWH9EQ | Branch: degod-follow-ups | Generated: 2026-07-02 Input: spec.md (rev 3), plan.md (IC-01..IC-08), research.md (D1–D10), data-model.md, contracts/
Pure-parity refactor: every WP is guarded by the four-layer parity contract (contracts/parity-contract.md). The chain is deliberately LINEAR — every relocation WP edits the shared tasks.py surface, so WPs sequence through dependencies (refactor missions linearize shared surfaces; parallel lanes would collide on the god-file).

Phase 1 — Foundation (parity floor)
WP01 — Parity floor: byte-freeze suite + LOC ceiling gate
Goal: Pin the exact bytes of all 13 JSON emission sites and land the LOC ceiling gate at 4569, BEFORE anything moves. Priority: P1 (blocks everything). Prompt: tasks/WP01-parity-floor-byte-freeze.md (~330 lines) Independent test: byte-freeze suite green against the untouched tree; LOC gate red on a synthetic over-ceiling source. Dependencies: none.

Phase 2 — Foundations (seam bridge + adapters + render seam)
WP02 — Shared-helpers module + seam bridge
Goal: tasks_shared.py houses the ~30 cross-family helpers with interception-preserving _tasks.<attr> routing; establishes the pattern every family move copies. Priority: P1. Prompt: tasks/WP02-shared-helpers-seam-bridge.md (~360 lines) Independent test: parity guard green; interception tests prove patches still bite; mypy strict clean on src+tests together.

- ✅ T014 tasks.py bindings + adapter seam checklist (WP03)
- ✅ T015 Parity guard + coord harness + ceiling ratchet (WP03)
WP04 — Render seam unification
Goal: One Render authority: RealRender gains constructor indent; _StatusRender deleted; all 12 compact sites route through the port. Priority: P1 (must precede the status-family move). Prompt: tasks/WP04-render-seam-unification.md (~340 lines) Independent test: 13/13 byte-freeze cases green through the swap; _StatusRender gone. Dependencies: WP03.

Phase 3 — Family relocations (one family per WP, ratchet re-point in the same WP)
WP05 — move_task family relocation (+ #2306 fold)
Goal: Largest family (orchestrator + 23 _mt_* + State + factory) to tasks_move_task.py; carries the C-001 divergence wiring and the #2306 inventory fold. Priority: P1. Prompt: tasks/WP05-move-task-family.md (~380 lines) Independent test: coord-harness skip-arm case (harness label T004: skip-exit-0 + wrong-leg detector) green; inventory gate green; parity green. Dependencies: WP04.

WP06 — map_requirements family relocation
Goal: _do_map_requirements + 11 _mr_* + State + factory to tasks_map_requirements.py. Priority: P2. Prompt: tasks/WP06-map-requirements-family.md (~280 lines) Independent test: coord-harness refuse-arm case (harness label T005: refuse-exit-1) green; parity green. Dependencies: WP05.
- ✅ T027 Create tasks_map_requirements.py (WP06)
- ✅ T028 Thin wrapper + bindings (WP06)
- ✅ T029 Ratchet re-point + coord refuse-arm case green (WP06)
- ✅ T030 Parity guard + seam checklist + ceiling ratchet (WP06)

- ✅ T031 Create tasks_status_cmd.py (WP07)
- ✅ T032 Thin wrapper + bindings (WP07)
- ✅ T033 Ratchet re-point: status (WP07)
- ✅ T034 Parity guard + ceiling ratchet (WP07)
WP08 — mark_status + finalize families relocation
Goal: The two remaining families to tasks_mark_status.py + tasks_finalize.py. Priority: P2. Prompt: tasks/WP08-mark-status-finalize-families.md (~300 lines) Independent test: coord refuse-arm case green for mark_status; parity green. Dependencies: WP07.

Phase 4 — Closure
WP09 — Registration-shim finalization + AST gate + shim disposition
Goal: Final tasks.py shape; AST 0-inline-dumps gate (all evasion forms); tasks_ports.py disposition; final ceiling min(achieved, 1400). Priority: P1. Prompt: tasks/WP09-shim-finalization-gates.md (~350 lines) Independent test: both gates green AND each red on synthetic violations; final LOC recorded with delta rationale. Dependencies: WP08.

WP10 — Boyscout: marker census + #2034 refresh
Goal: Committed census artifact (file → selecting gate, zero unselected) over the tasks-domain glob incl. all mission-added files; baseline-growth assertion; #2034 final refresh draft. Priority: P3. Prompt: tasks/WP10-marker-census-boyscout.md (~230 lines) Independent test: census artifact lists every glob-matching file with its gate; orphan baseline contains no tasks-domain path. Dependencies: WP09.
- ✅ T044 Marker-census artifact (WP10)
- ✅ T045 Baseline-growth assertion (WP10)
- ✅ T046 Draft final #2034 comment + issue-matrix verdicts (WP10)
Dependency graph (linear — shared-surface refactor)
WP01 → WP02 → WP03 → WP04 → WP05 → WP06 → WP07 → WP08 → WP09 → WP10Parallel opportunities: intentionally none across WPs (every relocation edits tasks.py and ratchets the same gate file — parallel lanes would collide). Within-WP subtasks marked [P] can interleave. The mission trades parallelism for zero-conflict certainty on a 4569-LOC god-file.
MVP scope
WP01 alone delivers standing value (the byte-level parity contract + the anti-regrowth ceiling); WP01–WP04 deliver the complete Stream A (render-seam unification) even if the relocations were paused.
