- core snapshot: build/parse (referential integrity, unknown fields stripped) + deterministic FNV-1a content hash; 2 pt-BR seed templates + json schema + validate script - db: lessons/lesson_items repo, exportTrackData, atomic importSnapshot (ordinal keys -> uuids, origin fields, rollback-proven) - worker: POST /share (bearer, 1MB cap, gzip to R2 + track_shares) and public GET /share/:id (cached), FakeR2 tests incl. cache-hit proof Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- lessons panel + editor on the track view (topic/content/quiz/note items, presenter notes, up/down reorder, 0-based quiz answers) - /present/[lessonId]: fullscreen slides, keyboard/touch nav, interactive quiz reveal, presenter view (notes, elapsed timer, next item) - TrackActions: export .studyos.json, share via worker (share url + uqr QR + copy), file import, origin_version update note - /import route: share-link preview + confirm, file import fallback - ci: validate templates step; e2e teacher-loop.cy.ts (5 specs) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Milestone 5 (teacher mode), complete — author a lesson, present it, share a QR, import on another device as a student track:
packages/core/snapshot): portable.studyos.jsonwith local ordinal keys (no uuids), structural validation with referential integrity, and a deterministic FNV-1a content hash (key-order stable,exported_atexcluded) shared verbatim by app and Worker.bun run validate:templates).exportTrackData+ atomicimportSnapshot(ordinal→uuid remap, origin fields, rollback-proven — a poisoned snapshot creates zero rows).POST /share(bearer, 1 MB cap, gzip via CompressionStream → R2 +track_sharesrow) and publicGET /share/:id(cached; students import without a token)./present/[lessonId]— fullscreen slides with keyboard/touch nav, interactive quiz (calm reveal, no confetti), presenter view with notes/elapsed timer/next-item;TrackActions— export, share with QR (uqr) + copy, file import, and theorigin_versionupdate note;/importroute with share-link preview.Tests
teacher-loop.cy.ts(5): author with quiz → present with quiz interaction + presenter view → share QR (stubbed worker) → export/reimport file roundtrip → import from share link🤖 Generated with Claude Code
