Turn the MVP into a self-contained demo. Users now:
1. Land on an empty-state and create a named session.
2. Drag-drop or pick arbitrary PDFs into that session.
3. Annotate, build evidence, link to form fields — all session-scoped.
4. Export the whole session as a single .zip archive (manifest +
per-document PDFs).
5. Import a .zip back — into a new session, or merged into an
existing one (documents deduped by SHA-256 fingerprint;
annotations/evidence/links added additively).
Architecture:
- New shared types: SessionId, Session, SessionArchiveManifest +
parseSessionArchiveManifest with schema-version validation.
- SessionService (engine/services/sessions.ts) handles lifecycle
(create/rename/delete/setActive) + emits 4 new events through its
own bus; SharedContracts.md §4 lists the additions.
- SessionProvider (work/SessionContext.tsx) owns the cross-session
state: service, per-session PdfByteStore registry, per-session
version counter that drives EngineProvider remounts after imports.
- EngineProvider becomes session-aware (sessionId prop drives per-
session localStorage keys). Bumping engineRevision after
restoreFromStorage forces consumers to re-render so restored repos
show up immediately.
- PdfByteStore (source/pdf/byte-store.ts) holds Uint8Array bytes per
document and mints blob URLs; ingestPdfFromFile is the upload
entry-point that wraps the existing ingestPdf pipeline.
- ADR-0008 locks the ZIP layout (manifest.json + documents/<id>.pdf),
the manifest schema (schemaVersion 1), and the merge-on-collision
policy. JSZip is the only new dependency.
- App.tsx restructured: SessionProvider at the root, EngineProvider
keyed by ${sessionId}:${version}, hash routing #/s/<id>[/forms/demo],
SessionMenu top-bar, CreateFirstSession empty state.
- New DocumentRemoved event for per-document delete cleanup in
CollectionList; engine.documents.remove() is the new service method.
Tests:
- Unit: 16 SessionService lifecycle + persistence tests;
per-session snapshot round-trip; PdfByteStore + ingestPdfFromFile;
SessionArchive parser; exportSessionZip + importSessionZip with
create + merge + corrupt-archive paths.
- DOM: UploadDropzone, session-scoped CollectionList delete,
SessionMenu create/switch/rename, routing parser.
- E2E: tests/integration/session-export-reimport.dom.test.tsx walks
the full create → annotate → export → reimport flow and asserts
the additive merge (deduped doc + doubled evidence rows).
- Legacy E2Es updated to use a seed-session helper instead of the
removed fixture-button flow.
Known limitation (documented in ADR-0008): re-importing your own
freshly-exported ZIP creates duplicate annotations. Forward pointer
left for an importBundleId follow-up.

/**

|
* Hash routing for the demo app.
|
|
*
|
|
* #/ → empty state ("create your first session")
|
|
* #/s/<sessionId> → review mode, scoped to <sessionId>
|
|
* #/s/<sessionId>/forms/demo → forms mode, scoped to <sessionId>
|
|
*
|
|
* The hash is the single source of truth for the active session and the
|
|
* active mode. `SessionProvider.setActive(...)` is wired as a side
|
|
* effect of hash changes so back/forward and deep links behave
|
|
* naturally.
