Simulations no longer color-code correct/incorrect choices, retry a
failed per-question autosave, or show the RZ coin/ELO badge - users
move on immediately after submitting a timed block, same as a real
exam. The slot machine panel now shows only the cabinet/reels/lever
and a status line (title, banner, controls row, rewards list, and
footer removed), the reels fill the cabinet window instead of
floating in a black border, the coin-burst animation no longer
starts oversized, and the toolbar button is UAT-only via
Brand.is_uat_environment().

Adds a spend-coins-for-a-random-reward mini-game reachable from the
shop. Backend mirrors the store's existing atomic/idempotent purchase
pattern (SpinAsync in CreditStore.cs) with a server-authoritative,
weighted reward roll and a rolling per-user spin-rate guard; odds are
served from GET /api/credits/spin-config so the client never hardcodes
numbers that could drift from the real payout table. The mockup's
"Streak Protector" reward was swapped for a real Exam Simulation Token
since streaks aren't currently a persisted, protectable concept.
Also fixes two latent bugs surfaced while building this:
- credits_service.gd's operation-id builder referenced a nonexistent
AuthState.user_id (should be .username), throwing on every credit
action.
- _post() silently no-op'd with no signal when signed out, which
combined with a GDScript closure gotcha (lambdas capture outer
locals by value, so reassigning inside one never reached the
caller) meant a spin attempted while unauthenticated could hang
forever instead of surfacing an error.
Adds a server-computed tier/division (Bronze..Diamond, III-I) to the
ratings profile endpoint and surfaces it next to the numeric ELO in the
shared header badge, matching the coin balance display already there.
Credits were previously awarded on any first attempt regardless of
correctness or timing. The award now requires the first-ever attempt
to be correct (record.Attempt.IsCorrect) and submitted before the
adaptive per-question timer expired (new MetTimeLimit request field,
computed client-side from the same elapsed/target comparison that
already drives the visible countdown bar). The coin-flight animation
in question_player.gd now only plays when both conditions are met
(BlockSessionService.submit_core_attempt's existing "mastered" flag
plus met_time_limit), so the effect never promises a coin that isn't
actually earned.

Wires the recently-merged question-completion-credits backend
(GET /api/credits) into the client for the first time: a new
CreditsService autoload fetches/caches the balance, and the embedded
credits field on first-answer responses updates it instantly with no
extra round trip. A shared CreditsBadge widget (star icon, balance,
decorative chevron per mockup) surfaces it in both the question
screen toolbar and the main shell header.

The optional "FOLLOW-UP QUESTIONS" reinforcement section shown during
answer review is now gated behind a Settings toggle (on by default),
persisted locally the same way as dark mode and interface sounds.
- Fix the toolbar wrapping onto two rows: its minimum width was tuned
for an older, narrower button set and never widened back out after
reverting to bare icon buttons.
- Drop the "Time elapsed"/"Ctrl+Enter" readout next to Submit - it was
clutter; the underlying timer logic keeps running unseen.
- Move the RanaZe brand mark above the question-count row instead of
sharing a line with it.
- Progress text drops the word "Question" everywhere ("1 of 10"), and
core/dynamic sessions now cycle against a configurable block size
(Settings > Question block size, default 10) instead of counting up
forever.
node_added already fires once per node as it enters the tree (including
every descendant of a newly-added subtree), so the recursive call_deferred
in _on_node_added was redundant and held a raw Node reference across a
frame boundary. If that node got freed before the deferred call fired
(e.g. a container torn down and rebuilt the same frame), the engine's
message queue couldn't marshal the argument and threw "Cannot convert
argument 1 from Object to Object". Wiring synchronously removes the
window entirely.
Also silences the intentional integer division in _duration_text,
matching the same annotation already applied to _elapsed_simulated_text.
Renames locals/params that shadowed base-class properties (Node.name,
Control.size, BoxContainer.alignment), prefixes an intentionally-unused
parameter, and annotates a deliberate integer division so the console
stays clean during development.
Two real gaps meant the account-synced zoom (from the previous
"sync through the account" change) never reached the screen:
_load_cache() updated AccountProfileService.preferences but never
emitted profile_changed, so question_player.gd/ccs_service.gd (already
built and listening before login even happens) never found out a
cached value had loaded. And nothing forced a server refresh
right after login - it only fired if the user happened to open the
profile/progress screen, so a fresh device/session had no path to
the true synced value at all.
main.gd now calls AccountProfileService.refresh() once per login
(not on every silent token refresh) so the real preferences GET
always runs right after signing in, on any device.
Also added Question bank/CCS case text size steppers to the Settings
screen next to dark mode, per user request, reusing the same
AccountProfileService/CCSService plumbing as the in-screen A-/A+
buttons.
Local user://settings.cfg meant zoom level didn't follow a student
across devices/browsers. Question bank and CCS text scale now live on
the user's study profile in Mongo (QuestionTextScale/CcsTextScale),
synced through a new PUT /api/profile/me/text-scale endpoint and the
existing preferences GET/cache already used for study preferences.
Both question_player.gd and ccs_service.gd read the synced value at
startup and react to AccountProfileService.profile_changed so a value
pulled down after login (or changed from another session) applies
without a restart. Backend validates the 0.85-1.35 range and updates
only the field(s) provided via a targeted $set, so it can't clobber
the other scale or the unrelated study-profile preferences.
Question bank and CCS case text-size (A-/A+) previously reset to 1.0
on every app launch. Both now load their saved scale from
user://settings.cfg at startup and save on every adjustment, mirroring
the existing pattern used for dark/light mode and sound preferences.
The warning was purely a token-expiry countdown with no concept of
user activity, so it interrupted people who had been clicking through
questions the whole time. AuthState now tracks real input activity
globally and silently refreshes the session in the background when
the user has interacted recently, only surfacing the "Stay logged in?"
dialog for sessions that are genuinely idle. A failed background
refresh still surfaces the dialog rather than silently logging the
user out.
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.
current_study_day_start_utc() passed use_space=true to
Time.get_datetime_string_from_unix_time(), producing "2026-07-21
00:00:00Z" (space separator) instead of ISO-8601. The server's
System.Text.Json DateTime converter rejects that with a 400, which
the client surfaces as a generic "could not be loaded" error -
blocking every study session. Confirmed against the live API: the
space-separated value 400s, the corrected T-separated value returns
a card.
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.
