StudySprint webapp v0.5.0

Surface release webapp v0.5.0, cut by the release-cut workflow (issue #4455 seam 3) from tag webapp-v0.5.0. Changes: see CHANGELOG.md at this tag.

Surface parity at this cut

Foundation: v0.5.0 · this surface: v0.5.0 (tag webapp-v0.5.0)

Parity matrix of record: evidence/PARITY-MATRIX.md at tag webapp-v0.5.0.

Surface × core feature-parity matrix (iteration 1 of #4282)

Ground truth: the shipped bindings, read from the surfaces'
own builders (web/build_data.py, tui.py: build_state, the
APK bundle = the web bundle) at core v0.5.0 + surface line
0.5.0. This matrix is the catch-up program's baseline;
every iteration updates it and the per-surface parity
statements together (standing surface gates). Owner rule (2026-11-03): this table rides every release body from v1.0.0 — release-cut embeds it verbatim from the cut tag; a pre-matrix tag’s body falls back to a named versions-of-record line. Legend:
bound = the surface runs the real core path ·
partial = a named subset, with the gap stated ·
absent = not on the surface.

Core capability (FEATURES.md)	CLI/core	webApp 0.5.0	TUI 0.5.0	APK 0.5.0
§1/§2 Plan + trust receipt + Today (§2/§3)	bound	bound	bound	bound (build-time state, disclosed)
§3 Daily check-in + no-guilt shift	bound	bound (persisted; surface-level shift, core reflow not bound)	bound (persisted; real week/day identity)	as webApp
§3 SR review — FSRS + SM-2, receipts	bound	bound (browser engines over the core UX export)	bound (real review_card)	as webApp
SR exports — Anki .apkg · Obsidian vault	bound	absent	bound (Export tab)	absent
§1/§3 Reader (sections + RSVP)	bound	bound (all 6 sections, 0.1.1)	bound	as webApp
§1 Intake — syllabus/textbook ingestion	bound	bound (in-browser grammar; photos = awaiting-core-ocr, disclosed)	bound (real ingest_any, confirm-gated)	bound (native file chooser + camera wiring)
§1b Reading pipeline — finder · OCR · structure · term bank	bound	bound (ingestion grammar + the demonstration book's bundle at build time: ingest receipt counts shown (62 terms mined · 62 with definitions · 2 with index refs — Darwin, Origin of Species 6th ed., Ch. XIV + the book's own Glossary + Index); term expansion in the Reader (core-emphasized segments; tap → term_tap_payload: definition · index pages · sections); hypothes.is annotations view over the sections (W3C model; API sync needs an account token, not configured); OCR: photographs recorded as awaiting core OCR — the browser cannot run tesseract, the named platform limit; finder stays the core's separate leg)	bound (the REAL pipeline live: Book tab over the bundled demonstration book (same counts), Ingest reports the three counts for any textbook via ingest_any; OCR seam wired through the core's tesseract default, provenance stamped ocr; hypothes.is annotations pane (W3C model, as webApp))	bound (as webApp)
§1c Multi-course + exam countdowns + .ics export	bound	bound (course set = both bundled samples intaken through the core's intake_courses; header switcher rebinds every view; SR + check-ins persist under per-course keys, legacy keys adopted once by the first course; countdown from the intake (port-pinned for user courses); .ics download = the core's per-course export; create-a-course from a syllabus document in Ingest)	bound (Courses tab: the real intake_courses set incl. user courses from ~/.studysprint/courses; switching rebinds all panes; check-ins persist per course in checkin-logs.json (the flat file keeps the active course's log); .ics export writes the active course's calendar file; create-a-course form persists the syllabus doc)	as webApp
§1c Memory methods — loci/palace · Feynman · retrievability notifications · interleaving · Leitner	bound	bound (Memory view: palace walk over iteration 1's temple route · Feynman pane · retrievability list with one-tap grades · Leitner in SR · interleaved plan — browser ports battery-pinned to the core)	bound (Memory tab runs the real core functions; Leitner via leitner_review; interleave in the Plan pane)	as webApp
§1d Calendar awareness — intake · frequency ramps · shift briefings · quiet hours	bound	bound (build-time state, disclosed)	bound (Calendar pane, live-assembled)	as webApp
§1d Geography — locations · routes · temple routes	bound	bound (build-time state, disclosed)	bound (Routes pane, live-assembled)	as webApp
§1d State recall + stress hardening (OPT-IN, ceilings in FEATURES §1d)	bound	bound (Hardening view: opt-in only, per-device flag off by default; ceilings verbatim; varied-context plan + reinstatement script + SIT drill plans (seeded pressure picks, receipt-reproducible) as browser ports battery-pinned to study_hardening; results record answered + 'not yet' with the supportive close — no score/penalty fields exist)	bound (Hardening tab runs the real study_hardening: opt-in persisted, off by default, refusal receipt when off; contexts + script + drill plan/result live)	bound (as webApp)
