24 tasks across 6 phases derived from the 2026-05-04 extension restructure
spec. Per-task bite-sized steps (TDD where new behavior, verify-existing-
tests where pure relocation) with explicit file/line citations and full
code snippets.
Phase 1 (StateHost typing, S-M, blocks 3+4): 5 tasks
Phase 2 (storage.ts + itemToManifestEntry, S): 3 tasks
Phase 3 (setup wizard SW migration + step registry, L): 7 tasks
Phase 4 (vault.ts split into 5 modules + vault_locked lift, M): 7 tasks
Phase 5 (P2 cluster: timer/gitHost/teardown/allSettled/debounce, M): 5 tasks
Phase 6 (get_vault_status + sidebar status indicator, S-M): 3 tasks
Task 7.1 (final verification sweep against spec Done criteria).
Recommended sequence: 1 → 2 → 5 → 4 → 6 → 3 (independents first, then
the typed-StateHost-dependent phases, then Phase 3 last because it's the
biggest single phase and benefits from all the supporting infra in
place). Max subagent parallelism: 3 streams.
Cross-plan: explicit out-of-scope notes for Plan A (security/docs polish,
already shipped) and Plan B (CLI restructure, already shipped). The
wasm.d.ts file is not touched by this plan (verify empty diff at done).
STATUS + ROADMAP updated to point at the plan.
