- Auto-load profile — pin one profile so it loads automatically when the app starts (DSx2-style). - Save a copy of any profile — quickly duplicate and edit without overwriting the original. - User-configurable DE1 fan threshold — choose the temperature at which the fan kicks in (was hardcoded). - Back-arrow exit during active flush — exit the flush page mid-flush without waiting. - Faster SAW convergence — stop-at-weight learning settles in fewer shots (N=5→3, graduation 2→1, read window 5→3). Refractometer & shot review - R2 auto-populate now only triggers on the active shot review page (avoids cross-contaminating older shots). - Refractometer readings below 3% TDS are rejected as unrealistic. - Temperature Unstable badge removed end-to-end — the detector was producing too many false positives. Bug fixes - Visualizer upload UI feedback restored on the post-shot review page. - Beans preset selection is preserved when clicking a favourite (no more accidental deselection). - On-screen start buttons are blocked when the group head controller (GHC) is active (prevents double-trigger). - QuickRatingRow font rendering fix. - Screensaver corrupt media files are now deleted and re-downloaded instead of cycling forever on the bad file. - Session marker re-emitted after log file trim (post-trim logs no longer look orphaned). BLE / connectivity - Scale reconnect timer now arms after a failed startup connection (no more "stuck disconnected" after first launch). - profileUploaded is correctly emitted when the firmware flash guard drops an upload (recipe page no longer hangs waiting). - Periodic CCCD re-writes stopped on all scales (was causing disconnects on Eureka Precisa and adding noise on others). - Redundant scale CCCD auto-enable removed. - Negotiated connection parameters + state logged at controller error for faster diagnosis. - ShotServer listen-socket health instrumentation added. AI advisor - Retries on 5xx and 429 responses from AI providers (transient errors no longer surface as failures). - Anthropic cache_control.ttl field type corrected; 400 error body now logged for easier debugging. - Decent's official dial-in targets and grind diagnostics for Adaptive v2 and Londinium profiles bundled into the advisor.

AI advisor knows your grinder. The advisor learns a personalized conversion from your shot history and gives concrete numbers ("try 16 on your Niche Zero") for every profile — not abstract guidance. Profiles you haven't pulled are labeled "starting estimate." The advisor learns from your follow-up shots. It now sees its own past recommendations on the same profile, whether you followed them, and whether predictions landed. It self-corrects mid-session instead of repeating the same hypothesis. Conversational rating. Reply to "how did this taste?" with a number ("82, balanced and sweet") and it's saved straight to the shot — no metadata editor needed. One-tap rating row. Three face icons (good / okay / bad → 80 / 60 / 40) appear on unrated shots in post-shot review. Tap to save instantly. The precision slider still works for finer scores. Auto-rating for clean shots. Shots that hit on-target yield and duration get a provisional 75 marked "inferred," so the AI's "best recent shot" anchor works even if you don't manually rate every shot. New Auto-Favorites grouping: Bean + Profile + Grinder + Weight. Splits cards by target yield and a 0.5 g dose bucket, so 18 g→36 g and 18 g→40 g recipes on the same grinder keep separate cards. Per-profile Stop-At-Weight learning. Switching between an open spout and double spout no longer cross-contaminates drip predictions. New "Puck failed" badge. Shots where peak pressure never built (massive channel, missing puck, severe underdose, way-too-coarse grind) now flag a single red chip with "Don't tune off this shot," instead of a misleading "Temp unstable" or "Clean extraction" label. Aborted shots are no longer saved. Tapping Stop during preheat used to clutter history with 0 g entries. Improvements - Profile-switch suggestions are ordered by grind direction (coarser first if shot ran slow, finer first if fast). - Less hallucination: the advisor verifies grinder numbers against your actual history before quoting them, and won't suggest a lever profile mid–turbo dial-in. - VoiceOver on the shot graph now announces phase name and units ("Preinfusion, 0.5 bar") instead of bare numbers. - AI dial-in is materially better at avoiding common mistakes — uses your grinder's smallest step, asks for taste before recommending changes, anchors on your highest-rated past shot in 90 days. - Auto-Favorites cards show target yield (what loads when you tap) instead of the most recent shot's reading. - Auto-Favorites Info/Show buttons correctly scope to the card's exact recipe in weight mode. - Settings → Machine card labels itself "Simulated" when in simulation mode. - Quality badges recompute when you open a shot, so detector improvements take effect on existing shots automatically. - Grind-issue detection now catches gushers (e.g. 18 g → 56 g actual on a 40 g target). - Accessibility status messages now route through VoiceOver in your chosen voice and language. Bug Fixes - Fixed iOS crash when tapping the dropdown chevron next to coffee/grinder autocomplete fields on iOS 26. - Fixed shot timer and steam timer rolling over at ~65 seconds. - Fixed Shot Summary dialog always appearing empty. - Fixed channeling false positives on Londinium-style profiles during the low-pressure preinfusion soak. - Fixed channeling and grind-issue false positives on lever profiles (80's Espresso, Cremina, Londinium). - Fixed Temp unstable false positives on cold-machine and aborted shots. - Fixed DE1 not auto-reconnecting after a failed startup connection. - Fixed update checker downgrading from beta builds to older stable releases. - Fixed the water refill warning ignoring your configured threshold. - Fixed steam duration not updating when switching pitcher presets mid-session. - Fixed edits being lost when navigating back from brew-recipe or post-shot review. - Fixed AI replies disappearing after closing an input dialog mid-conversation.
