CE-WP-0009 — Wire Umbrella to @citation-evidence/engine

Replace the in-repo src/shared/ and src/engine/ copies with a dependency on the extracted citation-engine package (@citation-evidence/engine).

Prerequisite: CENG-WP-0001 complete (engine extracted and tests green).

This workplan does not publish the package — it uses a local link: (or equivalent) dependency on the sibling checkout. Publishing is CENG-WP-0002.

Goals

1. Single canonical source for shared types and engine services (citation-engine).
2. Umbrella tests and app behavior unchanged after wireup.
3. ESLint boundary rules still enforce the dependency map (subsystems may not import each other's behavior; engine/shared come from the package).

Dependency order

T01 (add package dependency + resolve aliases)
  └─ T02 (point tsconfig / vite / eslint at package)
       └─ T03 (delete src/shared + src/engine)
            └─ T04 (verification: test + lint + typecheck + manual smoke)

T01 — Add @citation-evidence/engine dependency

id: CE-WP-0009-T01
status: done
priority: critical
depends_on: []
state_hub_task_id: "5e93d541-1485-466e-939a-eb0507d132c3"

Add a workspace-style local dependency on the sibling repo:

"dependencies": {
  "@citation-evidence/engine": "link:../citation-engine"
}

Run pnpm install and confirm node_modules/@citation-evidence/engine resolves.

Document the sibling-checkout requirement in README.md (engine repo must sit next to umbrella, same layout as today).

Acceptance: pnpm why @citation-evidence/engine shows the link target.

T02 — Retarget @shared/* and @engine/* aliases

id: CE-WP-0009-T02
status: done
priority: critical
depends_on: [T01]
state_hub_task_id: "97594063-e3d1-440f-a652-3e05efaf407f"

Update tooling so existing @shared/* and @engine/* imports keep working without rewriting every consumer file:

• tsconfig.json paths → node_modules/@citation-evidence/engine/src/shared/* and .../src/engine/* (or equivalent stable path through the link).
• vite.config.ts resolve aliases — same targets.
• eslint.config.js — remove shared and engine element patterns under src/; treat the package as external for boundary lint (subsystems still may only import @shared / @engine, not each other's folders).

Do not change import statements in anchor/, source/, binder/, work/, or app/ unless an alias path breaks.

Acceptance: pnpm typecheck passes before folder deletion.

---

T03 — Delete in-repo engine copies

id: CE-WP-0009-T03
status: done
priority: critical
depends_on: [T02]
state_hub_task_id: "bbd8b40d-900b-4ead-9487-e4064f5fc060"

Remove:

• src/shared/ (entire tree)
• src/engine/ (entire tree)

Update partition README pointers in remaining src/*/ folders to reference @citation-evidence/engine instead of "future home: citation-engine".

Acceptance: src/ contains only anchor/, source/, binder/, work/, app/ (plus any top-level app entry). No duplicate engine code in git.

---

T04 — Verification

id: CE-WP-0009-T04
status: done
priority: critical
depends_on: [T03]
state_hub_task_id: "8eb7411b-b0c7-414c-85ab-a08543869558"

• pnpm test — full suite green (integration + unit).
• pnpm typecheck — clean.
• pnpm lint — clean; boundary rules still catch illegal cross-partition imports.
• Manual smoke: dev server loads, PDF review → evidence → form link → export citation card (PRD §20 path).

Acceptance: CI-equivalent commands pass; no runtime import errors.

---

Out of scope

• Publishing @citation-evidence/engine to a registry (CENG-WP-0002).
• Extracting anchor/, source/, binder/, or work/ to sister repos.
• Resolving ADR-0002 (recommended before publish, not required for link:).
