bill ac81ec51f4 Sprint 1 complete: hybrid Compose + LibGDX architecture building

Full AL-001 through AL-008 implementation: shared/ module with ModuleType
enum, GameHost routing, StylusInputBridge, LineCorridorScreen with live
stroke rendering, LineScore (straightness + anglePrecision), score returned
to Compose hub via ActivityResult. Fixes LineScore field mismatch
(pressureConsistency → anglePrecision) caught during AL-009 build check.
Adds .gitignore and handoff notes.

Raw Blame History

Agent Handoff — May 8, 2026

Session Summary

Short session. Two things happened:

Build infrastructure unblocked — JDK 17 installed, APK compiles cleanly.
A LineScore field mismatch (stale pressureConsistency references) was caught by the compiler and fixed.

AL-009 (on-device smoke test) is unfinished — build passes but the physical device walkthrough hasn't happened yet.

What Was Accomplished

Build infrastructure

OpenJDK 17 installed via Homebrew (/opt/homebrew/opt/openjdk@17). The system Java wrappers symlink was not set up (requires sudo from a local terminal). Use the explicit JAVA_HOME form to build from the CLI:

JAVA_HOME=/opt/homebrew/opt/openjdk@17 PATH="/opt/homebrew/opt/openjdk@17/bin:$PATH" ./gradlew :android:assembleDebug

From IntelliJ (on the device machine) the JBR path from the previous handoff still applies:

JAVA_HOME="/Users/blindmouse/Applications/IntelliJ IDEA.app/Contents/jbr/Contents/Home" ./gradlew :android:assembleDebug

BUILD SUCCESSFUL — APK at android/build/outputs/apk/debug/android-debug.apk.

Three harmless deprecation warnings remain (Icons.ArrowBack → Icons.AutoMirrored.Filled.ArrowBack). Not worth fixing now.

LineScore field mismatch fixed

GameActivity.kt and MainActivity.kt were still referencing score.pressureConsistency and passing "pressureConsistency" as an Intent extra — left over from before LineScore was redesigned. Fixed both to use anglePrecision.

Still Open: AL-009 On-Device Smoke Test

Bill is SSH'd in and doesn't have a device attached to this machine. He'll pull from Gitea in a separate session with IntelliJ + S-Pen. Steps remaining:

./gradlew :android:installDebug (device must be connected via ADB)
Launch app → confirm Compose hub shows 4 module cards
Tap card → ModuleDetail with "Start Training"
Tap "Start Training" → LibGDX dark background + cyan corridor renders
Stylus pressure values visible in logcat
Complete stroke → score returned to ScoreCard on ModuleDetail

Once all steps pass, mark AL-009 DONE and close Sprint 1.

Still Open: Vector Drawing Module Design

Five questions from the May 7 handoff are still unanswered. Do not write MODULES.md entries or any implementation for the vector module until bill answers them. See HANDOFF_2026-05-07.md for the full question list.

Design Philosophy Note

Bill pushed back on framing ArtLegend as a platform for people who "fail" at art. His view: art is expression, there is no failure state. ArtLegend teaches rendering specifically — it builds the physical vocabulary that lets artists execute what they imagine. Confident rendering lowers the activation energy for creative risk. Don't frame the app around deficits.

Broader Reminders

Design before code. When mechanics are ambiguous, discuss and document in MODULES.md first.
The current LineCorridorScreen and LineScore are placeholders. The real Corridor Scroll is a real-time scrolling tracker, not a single-stroke scorer. Don't build on top of the current scoring without revisiting it.
Keep MODULES.md updated. It exists to prevent re-explanation each session.
