- Add gameHistory configs to all 21 test student profiles
- Implement generateGameResults function to create scoreboard data
- Each profile has appropriate game history matching their characteristics:
- Struggling students get low scores (35-45)
- Developing students get medium scores (55-75)
- Strong students get high scores (78-95)
- Add accuracyMultiplier to TuningAdjustment interface (fixes TS error)

Add MIN_SECONDS_PER_PROBLEM (10s) to clamp the average time calculation
and prevent generating 100+ problems when student timing data is
anomalously low (e.g., 2-3 seconds per problem).
- Add MIN_SECONDS_PER_PROBLEM constant in session-timing.ts
- Apply Math.max() clamp in generateSessionPlan()
- Fix seed script to use realistic 30s timing instead of 5s
A 5-minute session at 10 sec/problem = 30 problems (reasonable)
A 5-minute session at 2 sec/problem = 150 problems (too many)

Major refactoring of worksheet parsing to use centralized state management:
New architecture:
- WorksheetParsingContext: React context provider for parsing state
- state-machine.ts: Typed reducer with actions for streaming lifecycle
- sse-parser.ts: Shared SSE parsing utility for OpenAI Responses API
- usePartialJsonParser.ts: Progressive JSON extraction during streaming
Streaming UI improvements:
- ParsingProgressOverlay: Dark overlay on photo tile during parsing
- ParsingProgressPanel: Collapsible reasoning text panel
- ProgressiveHighlightOverlay: Problem boxes light up as LLM parses
- New streaming API routes: /parse/stream and /parse-selected/stream
Bug fixes during testing:
- Fix TypeScript error: cast event.response for id access in sse-parser
- Fix reparse reasoning display: preserve "processing" status for reparse
- Fix concurrent parsing: revert previous attachment status when switching
- Fix problem count: track dispatched problems to prevent duplicates
Components updated to use context:
- SummaryClient: Wrapped with WorksheetParsingProvider
- OfflineWorkSection: Uses context instead of local streaming state
- PhotoViewerEditor: Uses context for coordinated parsing

- Add cancel button to gallery thumbnails when parsing in progress
- Add cancel button to fullscreen PhotoViewerEditor when parsing
- Add cancel button for re-parsing in progress (fullscreen view)
- Track reparsingPhotoId to show correct status per-photo in both views
- Gallery shows "Re-parsing..." badge on specific photo being re-parsed
- DELETE endpoint resets parsing status for immediate retry
Also includes codebase-wide formatting from biome.

- Fix hook dependency issues in AbacusVisionBridge by using destructured
stable function references instead of remoteCamera object
- Add proper container dimension tracking for remote camera calibration
overlay to fix coordinate mismatch
- Add rotate180 option to perspectiveTransform to support both Desk View
(camera pointing down, needs 180° rotation) and phone cameras (no rotation)
- Phone camera cropping now uses direct mapping without rotation
The main issues fixed:
1. Hook dependencies were causing effects to run repeatedly when navigating
to remote camera URL in a different window
2. CalibrationOverlay was using hardcoded fallback dimensions instead of
actual container dimensions for remote camera
3. Perspective transform was applying 180° rotation which is wrong for
phone cameras held at normal angles

Major changes:
1. Sentinel approach for skill recency refresh
- Added 'recency-refresh' session status and SlotResult source field
- BKT skips pKnown updates for sentinel records (zero-weight)
- refreshSkillRecency() now inserts sentinel records instead of updating DB field
- Single source of truth: all lastPracticedAt comes from problem history
2. Skill progress chart (new component)
- 100% stacked area chart showing skill distribution over time
- Clickable legend cards for filtering by classification
- Adaptive time window presets (Recent, Last N, All)
- Synthetic "current" snapshot ensures chart matches legend staleness
3. Trend-aware encouragement messages
- Linear regression to detect improving/declining/stable trends
- Session timing analysis (gap detection, frequency patterns)
- Window-aware scope text ("over the past 2 weeks", "since Nov 15")
- Priority-based message selection (urgent issues first)
- Consistent "stale" terminology (not "rusty")
4. Dashboard improvements
- Virtualized session history list for performance
- Paginated session history API with cursor-based pagination
- BKT-computed lastPracticedAt used throughout (single source of truth)

Fixed the seed script to reliably produce "developing" skill classifications
(pKnown 0.5-0.8) by correcting several issues:
- Fix BKT simulation to only apply learning transition after CORRECT answers
(matching actual updateOnCorrect vs updateOnIncorrect behavior)
- Remove result shuffling to preserve designed correct/incorrect sequence order
- Force single-skill problem annotations to avoid multi-skill blame distribution
- Add multiple pattern generators for finding developing-range sequences
The simulation now accurately predicts actual BKT outcomes, enabling 10
developing classifications across 6 test profiles.

- Add simulateLegacyData option to SkillConfig interface
- When set, generateSlotResults omits helpLevelUsed field to simulate legacy data

- This tests the actual production issue where old sessions lack helpLevelUsed

All 15 profiles now have correct category assignments:
- 5 BKT profiles (category: 'bkt')
- 4 Session profiles (category: 'session')
- 6 Edge case profiles (category: 'edge')
This enables CLI filtering when seeding specific profile types.

Previously, skill stats (attempts, correct, accuracy) were stored as
persisted aggregates in playerSkillMastery and updated incrementally.
This caused issues with seeded test data showing "0 correct".
Now:
- analyzeSkillPerformance() computes stats from session results on-the-fly
- findStrugglingSkills() computes accuracy from session results
- Seeder no longer needs to update aggregate columns
Benefits:
- Single source of truth (session results)
- No drift between aggregates and actual data
- Seeded data automatically works correctly
