T01: shared engine types (Document, Selector union, Annotation, EvidenceItem,
branded IDs with newId factory) per wiki/SharedContracts.md §1-§3.
T02: react-pdf-highlighter-plus v1.1.4 spike behind the §5
DocumentViewerAdapter contract in src/anchor/. Pure round-trip math
extracted to pdf-selector-math.ts with 11 unit tests proving lossless
capture → selectors → JSON → restored-rects. ADR-0004 accepted; full
user-flow Playwright verification deferred to T09.
Adds Vite app shell (index.html, src/app/SpikeApp.tsx) so the spike is
exercisable via pnpm dev. tsconfig --noEmit prevents tsc -b from
littering src/ with stray .js outputs.

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.
