Single forward-looking reference that replaces the two untracked planning
docs (REFACTOR_PLAN.md + REFACTOR_EXECUTION.md) which had become a mix of
historical PR timeline and still-relevant decisions.
Keeps only what's actionable going forward:
- Module tiers, the four registries, and the module distribution model
(architecture summary).
- Remaining work: Phase 5 (v2 → main) and the modules-branch decision.
- Operational patterns worth preserving (standing checks, TDZ rule,
branch-sync file-presence diff procedure, prettier drift pattern).
- 17 curated open questions across design, distribution, core slotting,
and documentation.
Canonical references (docs/module-contract.md, docs/architecture.md, etc.)
are linked but not duplicated. This doc is transient — retire when the
refactor is fully behind us.
