System decks/notes are owned by a reserved sentinel user id, reusing
all existing per-user store/index plumbing unchanged. Regular users
see them under a separate "Official Decks" section, can study them
with fully independent per-user FSRS progress (lazily materialized on
first visit), but can never edit or archive them - enforced both in
the client (no Edit/Archive controls) and server-side (ownership guard
on every mutating endpoint). Includes a small idempotent seed command
(`dotnet run -- seed-flashcards`) for testing, since there's no in-app
authoring UI yet.
Add real session-history navigation (Previous/Next/Shuffle), compact
side panels, and a segmented progress row to match the mockup layout.
Flashcards now opens straight into Study, with library management
moved into the Options menu ("Manage Flashcards") and Export hidden
from the UI (Import stays). Shuffle is backed by a real, due-before-new
randomized pick on the backend, not a decorative toggle.
Study screen now matches the provided mockup's layout: a "Current
Deck" panel with a circular mastery-progress ring, and a "Spaced
Repetition" panel (New/Due/Learning/Review counts, streak, daily
goal) on either side of the card. Kept the app's real global sidebar
rather than the mockup's own nav, per direction.
Mastery/Streak/Daily Goal weren't tracked anywhere, so this adds real
backend support rather than showing fabricated numbers:
- Mastered = graduated to review state AND FSRS stability >= 21 days
(FlashcardScheduleStore.MasteryStabilityDaysThreshold), stricter
than the plain Review-state count
- CurrentStreakDays = consecutive UTC days with a review, computed
from review-log timestamps in the new pure FlashcardScheduling
.ComputeStreakDays (unit tested, habit-streak semantics: doesn't
reset to 0 the instant a new day starts before today's first review)
- DailyGoal/ReviewsToday reuse the account's existing ReviewsPerDay
setting rather than inventing a new one
Also removes the exit "X" button in favor of the same Escape/pause
menu the question-player flow uses (main.gd's shared app_menu, with
an "Exit Study Session" action), and adds a new circular_progress.gd
reusable ring control plus a real "Options" menu (bury/suspend the
current card) wired to schedule endpoints that had no UI before.
refresh_theme_controls() colored the divider and the ANSWER/KEY
TAKEAWAY captions, but it only ran on an actual theme toggle - never
at initial build. Confirmed live: the divider was invisible (default
white on a white card) and the captions rendered as plain body text
instead of the intended accent color until you toggled dark mode
once. Call refresh_theme_controls() once at the end of _build() so
the correct colors apply immediately, which also fixes the same
latent gap in empty_label's color.
Study card: label the answer and "key takeaway" as distinct sections
with a real visible divider (previously an all-but-invisible
HSeparator) instead of one undifferentiated block of text. Also fixes
a real gap where a cloze card's extra field was silently dropped,
since only basic notes combined answer+extra into one label. Bigger
card, gradient Show-Answer button matching the app's signature CTA
style instead of a duller flat teal, and the Undo button now hides
itself when there's nothing to undo instead of sitting there disabled
looking identical to a real action.
Library: colored type badge per card (Basic/Cloze) instead of plain
gray text, more breathing room inside each row, Study promoted to the
same gradient CTA style, and Edit/Archive given a real secondary
button treatment instead of default theme buttons. Note editor fields
renamed ("Back / Extra takeaway" + a separate "Extra" field was
genuinely confusing) and now show which deck a card is being saved to.
Import and export were stubbed with status-text placeholders; wire them
to the existing backend endpoints with a real file picker (web JS
bridge or native FileDialog) and browser/desktop download, plus an
import preview with create/update/skip/error counts before commit.
Also fix the library and study screens' theme-refresh handlers, which
were no-op stubs so cards never restyled on a theme toggle, and add
responsive layout handling for narrow viewports.
Adds a full flashcards system: FSRS-based scheduling, cloze/basic
card types, CSV import/export, media storage, and study UI, wired
into navigation and the dashboard alongside existing question flows.
