# WP-01 — Canonical contracts & 2-domain fixtures

**Purpose:** Establish source-independent knowledge projection and the zero-UI-code-change experiment.

**Dependencies:** see `INDEX.md`. **Status:** planned. **Owner:** to assign. **Estimate:** to refine after WP-00.

## Work packages

- [ ] Freeze v0.1 snapshot schema and manifest schema; document migrations.
- [ ] Model entity IDs, kinds, directed relations, evidence and claims in TS/Zod.
- [ ] Normalize systems-thinking and software-architecture fixtures with independently authored prose.
- [ ] Write duplicate, dangling, cyclic non-taxonomy and missing-source tests.
- [ ] Define policy for unknown and conflicting facts.

## Acceptance gates

- [ ] Both fixtures validate and supply ≥3 kinds and ≥8 entities each.
- [ ] A shared renderer can switch manifests with no domain vocabulary in UI source.
- [ ] Snapshot format documented and versioned.

## Key risk / mitigation focus

R3: abstractions erase domain semantics. Log evidence and deviations in the workplan review before marking complete.

## Evidence artifacts

Pull requests, test logs, pinned artifacts, screenshots or comparison report where applicable. Add explicit `ImplementationNotes.md` and `Review.md` on completion; do not mark a gate passed without a verifiable link.
