Created BreadCalc-DIARY.md (frontend/80-Kitchen/apps/BreadCalc/) as the standing build log for a new companion system to DoughCalc that USR369 spec'd out this session: a simplified dough calculator (DoughCalc's core math, no pizza mode, no pan-sizing tools -- everything else including bake temp/time and directions stays) paired with a new percentage-aware Bread Recipe Library, fully separate from both DoughCalc's own presets and Kitchen's general Recipes app. Requested specifically because this project is intended to eventually go to CC[100] for Android packaging (SOP-APP-BUILD-LANES.md) -- USR369 wants a full history attached before that handoff happens. First diary entry captures the complete requirements-gathering conversation (which changed shape more than once before landing correctly) rather than starting the diary only once code exists, matching DoughCalc-DIARY.md's own established format (chronological, dated entries, root-cause/decision framing). Flagged 4 open questions in the diary rather than assuming answers: working names not yet confirmed, color scheme not yet confirmed, import-mechanics scope (manual conversion vs auto-parse) not explicitly re-confirmed after being raised, and extra-ingredient entry mode treated as confirmed-by-inference rather than explicit confirmation. No app code written yet -- this is a planning/diary-only entry, actual build starts next session or later this session.
