From 0b53023a25b2e16d471605e95202b9c802aefe7d Mon Sep 17 00:00:00 2001 From: Kyle Isom Date: Tue, 24 Mar 2026 14:03:57 -0700 Subject: [PATCH] Implement Phase 1: project skeleton and data layer Android project with Kotlin, Jetpack Compose, and Room. Includes: - Gradle build system with version catalog, foojay JDK resolver, lint config - Room entities (Notebook, Page, Stroke) with packed float BLOB encoding - DAOs and repositories for all entities - Unit tests for blob roundtrip and PageSize enum (10 tests, all passing) - Minimal Application class and stub MainActivity Co-Authored-By: Claude Opus 4.6 (1M context) --- .gitignore | 13 +
