FoodFinder adds barcode scanning, AI camera analysis, voice search, and text-based food lookup to Loop's carb entry workflow. All feature code lives in dedicated FoodFinder/ subdirectories with FoodFinder_ prefixed filenames for clean isolation and portability to other Loop forks. Integration touchpoints: ~29 lines across 3 existing files (CarbEntryView, SettingsView, FavoriteFoodDetailView). Feature is controlled by a single toggle in FoodFinder_FeatureFlags.swift. New files: 34 (11 views, 3 models, 13 services, 2 view models, 1 feature flags, 1 documentation, 3 tests)
Voice search (microphone button) now uses the AI analysis pipeline instead of USDA text search, enabling natural language food descriptions like "a medium bowl of spicy ramen and a side of gyoza". Text-typed searches continue using USDA/OpenFoodFacts as before. Changes: - SearchBar: Add mic button with voice search callback - SearchRouter: Add analyzeFoodByDescription() routing through AI providers - SearchViewModel: Add performVoiceSearch() async method - EntryPoint: Wire VoiceSearchView sheet to AI analysis pipeline
Replace the separate mic button with automatic natural language detection. When the user dictates into the search field via iOS keyboard dictation, the text is analyzed: short queries (1-3 words like "apple") use USDA, while longer descriptive phrases (4+ words like "a medium bowl of spicy ramen and a side of gyoza") automatically route to the AI analysis path. Changes: - SearchBar: Remove mic button and onVoiceSearchTapped parameter - SearchViewModel: Add isNaturalLanguageQuery() heuristic, route detected natural language through performVoiceSearch in performFoodSearch - EntryPoint: Remove voice search sheet, wire onGenerativeSearchResult callback to handleAIFoodAnalysis
The Python script created group definitions but didn't properly attach all of them to their parent groups. Fixes: - Services group → now child of Loop app root (was orphaned) - Resources group → now child of Loop app root (was orphaned) - Documentation group → now child of project root (was orphaned) - ViewModels/FoodFinder → moved from Loop root to View Models group - Tests/FoodFinder → moved from project root to LoopTests group
…, analysis history - Fix triple barcode fire by consuming scan result immediately in Combine sink - Replace AsyncImage with pre-downloaded thumbnail to avoid SwiftUI rebuild issues - Use smallest OFF thumbnail (100px) with static food icon fallback for slow servers - Add secure Keychain storage for AI provider API keys - Add analysis history tracking with FoodFinder_AnalysisRecord - Consolidate AI provider settings and remove BYOTestConfig
- Remove barcode connectivity pre-check that added 3+ seconds latency per scan - Add NSCache to ImageDownloader for thumbnail deduplication (50 items, 10MB) - Remove artificial minimumSearchDuration delay from search and error paths - Merge duplicate Combine observers into single combineLatest for AI recomputation - Decode image_thumb_url from OpenFoodFacts API for smallest available thumbnail - Wrap 369 bare print() calls in #if DEBUG across 8 FoodFinder files

- Add originalAICarbs and aiConfidencePercent fields to FoodFinder_AnalysisRecord for tracking AI estimate accuracy - Add Notification.Name.foodFinderMealLogged for real-time meal event observation - Add MealDataProvider protocol with date-range query interface and AnalysisHistoryStore conformance - Add "Last 30 days" retention option to Analysis History settings
- Absorption time model: conservative adjustments anchored to Loop's 3-hour default. FPU adds +0/+0.5/+1.0 hr (was +1/+2.5/+4), fiber +0/+0.25/+0.5 (was +0/+1/+2), meal size +0/+0.25/+0.5 (was +0/+1/+2). Cap reduced from 8 to 5 hours. Updated AI prompt and 3 examples. - OCR routing fix: raised menu detection threshold from 1 to 5 significant lines and always include image on menu path to prevent food photo misclassification (fixes "Unidentifiable Food Item" on food photos). - Inline "Why X hrs?" pill on Absorption Time row replaces standalone DisclosureGroup row. Purple centered pill with fixed width, expands reasoning on tap. Uses AIAbsorptionTimePickerRow when AI-generated.
Add LoopInsights feature: an AI-driven therapy settings advisor that analyzes glucose, insulin, and carb data to suggest adjustments to Carb Ratios, Insulin Sensitivity Factors, and Basal Rates. Core components: - Dashboard with therapy settings overview, pattern detection, and AI suggestions - Configurable AI provider (OpenAI, Anthropic, Gemini, Grok, self-hosted) - Data aggregation pipeline with test data fixtures from Tidepool - Suggestion lifecycle: pending → applied/dismissed with full history - AI personality settings (Supportive Coach, Clinical Expert, Dry Wit, Tough Love) - Developer mode with auto-apply and test data toggles - Secure API key storage via Keychain - Safety guardrails: max 20% change per adjustment, one setting at a time - Unit tests for models, data aggregation, and suggestion store 22 new files, 4 modified files across Views, View Models, Models, Services, Managers, Resources, and Tests.

The 20-char limit was truncating food names (e.g. "Baked pastry with f…") which made them unreadable in LoopInsights Meal Insights. The RowEmojiTextField maxLength only restricts keyboard input, so longer programmatic values are safe. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…rtion control DataLayer: wire barcodeScanned, chatMessage, mealDebrief, therapySettingsChanged, overrideActivated/Deactivated, activityDetected, biometricSnapshot events. FoodFinder: fix location race condition — request GPS on camera button tap and wait up to 1.5s for reverse geocode before AI analysis. Restructure food detail cards with per-item USDA serving steppers so users can fine-tune portion estimates independently. Nutrition circles and totals update live with stepper changes. AI prompt: clarify serving_multiplier = visible portion / USDA serving with examples.
…rompt - Remove 500ms cosmetic delays after analysis success/error in AICameraView - Add fast VNDetectTextRectanglesRequest gate before expensive OCR — skips full text recognition when <5 text regions detected (most food photos) - Consolidate mandatory prompt rules (43 → 13) and remove 2 of 3 worked examples, keeping the high-GI Teriyaki example most relevant for diabetes
Shows relative timestamps ("2 hours ago", "in 4 hours") so the user
can verify background monitoring is actually running on schedule.
- Remove unused extractNumericConfidence(), shouldUseParallelProcessing, and createPlaceholderImage() from FoodFinder services/view models - Add onDisappear to clear cached location when FoodFinder is dismissed
Defer prediction snapshot capture to next .LoopDataUpdated instead of capturing immediately on .foodFinderMealLogged. StatusExtensionContext predictions are stale until the Loop algorithm re-runs with the new carbs — capturing immediately was the primary cause of "no prediction data captured" failures in Meal Insights.
A1: Extend AutoPresets Stop Delay slider from 10min max to 2hr max with dedicated value steps (10s, 20s, 30s, 1m, 2m, 3m, 5m, 10m, 15m, 20m, 30m, 45m, 1hr, 1.5hr, 2hr) for post-exercise recovery. F5: Add mandatory pre-bolus timing advisory to FoodFinder AI prompt for all analyses (not just advanced mode). Recommends bolus timing based on GI category, meal composition, and current glucose. N5: Add user engagement/burnout awareness to LoopInsights AI system. Teaches AI to interpret low carb logging, declining corrections, and high suggestion reversion as possible disengagement signals. Computes engagement metrics in supplemental context for every analysis.
Remove advanced-mode gate on absorption time recalculation so fat/ protein adjustments always apply when items are removed. Increase high-FPU adjustment from +1.0h to +1.5h and raise total cap from 5h to 6h to better handle pizza/nachos/high-fat meals that cause delayed glucose rises.
Capture glucose stats (TIR, avg, below-range, CV) at suggestion apply time via new LoopInsightsGlucoseStatsSnapshot. Show "Settings Impact" section on dashboard with recently applied suggestions, days-since, outcome verdict, key metrics at time of change, and AI reasoning.
…data Analyzes FoodFinder meal history for systematic user corrections by food type, location, time of day, and AI confidence level. Surfaces patterns as alerts on the dashboard and in a dedicated Behavior Insights view. Injects patterns into AI supplemental context and Post-Meal debrief prompts for richer recommendations. Also makes Settings Impact section collapsible via DisclosureGroup.
…ights Adds one-tap PDF report for endocrinologist appointments with branded LoopInsights teal header, toggleable sections, vertical Dexcom Clarity-style Time in Range bar, detected glucose/insulin patterns, behavior correction patterns, and custom email subject line. Report covers glucose, insulin, nutrition, settings changes, biometrics, engagement, caffeine/alcohol, and pump suspensions.
…very Configurable digest for caregivers with recipient email/phone storage, delivery method picker (Email or iMessage), frequency (daily/weekly), and personalized greeting. Send Now generates summary and opens pre-filled compose view — recipient just taps Send. Includes TIR, glucose stats, insulin delivery, and meal data.
Automatically activate presets when arriving at or leaving saved locations (gym, office, park) using iOS region monitoring. Battery-efficient — no continuous GPS tracking. Includes map picker, radius config, trigger type selection, and full integration with existing AutoPresets activity log.
EventKit integration that scans calendars for keyword-matched events and auto-activates presets with configurable lead time. Supports all calendar providers, per-calendar filtering, and deactivation on event end.
Replaces the existing minimal chart touch highlight with a rich detail popup showing glucose, IOB, COB, bolus, basal, preset, AutoPreset, and heart rate data at any point on the glucose chart. Supports scrubbing left/right with haptic feedback, auto-fades after 5 seconds, respects safe areas in both orientations, and works standalone with optional enhanced data when other features (AutoPresets, etc.) are enabled.
Only on feat/AllFeatures — individual feature branches keep stock Loop icon. Replaces all 18 tracked PNGs in DerivedAssetsBase with purple PowerPack icon.

Summary
How many times have you changed your pump site or CGM sensor and thought "wait, where did I put the last one?" Site Atlas tracks where you place your infusion set, tubeless pump or sensors on a visual body map so you never have to guess. Proper site rotation prevents tissue damage (lipohypertrophy) that messes with insulin absorption and sensor accuracy. Inspired by Shaun Sabo's work on Site Cycle. Part of the Loop AI PowerPack.
The Problem That We're Solving
People with Type 1 diabetes need to rotate where they place pump infusion sets and CGM sensors. Reusing the same spots causes scar tissue that absorbs insulin unpredictably and gives less accurate CGM readings. But there's no way to track this in Loop today — most people just try to remember, and memory isn't reliable when you're changing sites every 3 days for decades.
New Feature's Impact
Site Atlas adds a visual body map where you log your pump and sensor placement. Color-coded pins tell you at a glance which areas are fresh (red=avoid) vs. healed (green=safe to reuse). The app suggests where to go next based on which sites are oldest.
