# Agent Handoff — May 8, 2026

## Session Summary

Short session. Two things happened:

1. Build infrastructure unblocked — JDK 17 installed, APK compiles cleanly.
2. 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.
