Implement CE-WP-0001 Foundations: TS scaffold, lint boundaries, normalize v1, fixtures

T01 Toolchain — vite + pnpm 9.15 + React 18 + strict TS (ADR-0001).
T02 Folder layout — src/{shared,engine,anchor,source,binder,work,app}/
    mirroring the future subsystem split, with path aliases.
T03 Boundary lint — eslint-plugin-boundaries enforcing the dependency
    edges from wiki/DependencyMap.md §4; verified by a violating fixture.
T04 Canonical normalization v1 — src/shared/text/normalize.ts with
    NORMALIZE_VERSION=1; 10/10 vitest covering ligatures, CRLF, soft
    hyphens (including line-break reassembly), mixed whitespace.
T05 PDF fixture corpus — 7 user-supplied German PDFs in fixtures/pdfs/
    (gitignored binaries) plus a manifest with verbatim known-good
    quotes and page counts, ready for CE-WP-0002 selector tests.
T06 README upgrade — umbrella README points at wiki/docs/workplans
    and documents the dev workflow.
T07 ADR-0002..0006 stubs in docs/decisions/.

Toolchain end-to-end: pnpm install + lint + typecheck + test all green.

-document-centered evidence workspace for capturing, managing, presenting, and re-opening citations 
+# citation-evidence
+
+A document-centered evidence workspace for capturing, managing, presenting,
+and re-opening citations. The umbrella over the six-package design described
+in `INTENT.md` and `wiki/ArchitectureOverview.md`.
+
+During the MVP all code lives here under `src/` (see "Repository layout"
+below). Sister repos hold INTENT only — code migrates outward when each
+subsystem stabilises.
+
+## Documentation
+
+| Where                  | What                                                    |
+|------------------------|---------------------------------------------------------|
+| `INTENT.md`            | Project intent, scope, the umbrella-first decision      |
+| `wiki/`                | PRD, Architecture, SharedContracts, DependencyMap       |
+| `docs/decisions/`      | ADRs (architecturally significant decisions)            |
+| `workplans/`           | Ralph-driven workplans that implement the MVP slice     |
+| `history/`             | Time-stamped assessments and post-mortems               |
+
+The canonical contracts are in [`wiki/SharedContracts.md`](wiki/SharedContracts.md);
+the partition boundaries are in [`wiki/DependencyMap.md`](wiki/DependencyMap.md).
+Both are referenced from every workplan and from each sister repo's INTENT.md.
+
+## Repository layout
+
+```
+src/
+  shared/   # vocabulary, types, pure helpers      → becomes part of citation-engine
+  engine/   # services, repositories, event bus    → becomes part of citation-engine
+  anchor/   # selector creation/resolution, viewer adapter contract → becomes evidence-anchor
+  source/   # ingest, fingerprint, extraction, recovery → becomes evidence-source
+  binder/   # evidence-to-target binding, visual guide → becomes evidence-binder
+  work/     # review UI (sidebar, viewer shell)    → becomes citation-work
+  app/      # the reference workspace shell        → stays in citation-evidence
+```
+
+The dependency-edge rules between partitions are enforced by ESLint via
+`eslint-plugin-boundaries` (see `eslint.config.js`). Extraction to a sister
+repo is intended to be a `git mv` plus a `package.json` cut — nothing more.
+
+## Sister repos
+
+Peers under `~/`; each holds INTENT.md only during MVP:
+
+- [`~/citation-engine`](../citation-engine/) — shared model + engine services
+- [`~/evidence-anchor`](../evidence-anchor/) — selectors + adapter contract
+- [`~/evidence-source`](../evidence-source/) — ingest, representation, recovery
+- [`~/evidence-binder`](../evidence-binder/) — binding, visual guide, rect registry
+- [`~/citation-work`](../citation-work/) — review UI surfaces
+
+## Dev workflow
+
+Requirements: Node 20 LTS (see `.nvmrc`) and `pnpm` 9.
+
+```bash
+pnpm install
+pnpm dev        # vite dev server (once src/app/ has a real entry)
+pnpm test       # vitest one-shot
+pnpm test:watch
+pnpm lint       # eslint with boundary rules
+pnpm typecheck  # tsc --noEmit
+pnpm build      # production bundle
+```
+
+## Workplans (Ralph)
+
+Workplans drive incremental implementation through the ralph loop. The harness
+lives in `~/ralph-workplan/`; see `workplans/README.md` for the active list
+and ordering.
+
+```bash
+/ralph-workplan workplans/CE-WP-0001-foundations.md
+```
+
+The loop self-retires when every task in the file has `status: done` and the
+workplan's frontmatter `status: done`.
