+# Brainstorm & Implementation Plan — Android 24/7 Radio
+
+**Date:** 2026-03-09
+
+## Task Description
+
+Brainstormed and designed a personal-use Android radio streaming app from an IDEA.md spec. Produced a full design document and a 15-task implementation plan.
+
+## Key Decisions
+
+- **Custom raw audio pipeline** (Approach B) over ExoPlayer, for absolute minimum latency (~26ms per MP3 frame vs ExoPlayer's ~1-2s floor)
+- **Pipeline:** OkHttp → IcyParser → Mp3FrameSync → MediaCodec → AudioTrack, single-threaded
+- **Kotlin + Jetpack Compose + Material 3**, targeting API 28 (Android 9) minimum
+- **Room DB** with future-proofed schema (MetadataSnapshot, ListeningSession, ConnectionSpan tables for future recording/clips)
+- **PLS/M3U import/export** with `#EXTIMG` support for station default artwork
+- **Album art fallback chain:** MusicBrainz → ICY StreamUrl → EXTIMG → Station favicon → Placeholder
+- **Dual timers** on Now Playing: session time (never resets) + connection time (resets on reconnect)
+- **Latency indicator** estimated from ring buffer + AudioTrack write/play head delta
+
+## Changes Made
+
+- `docs/plans/2026-03-09-android-247-radio-design.md` — Full design document (6 sections)
+- `docs/plans/2026-03-09-android-247-radio-implementation.md` — 15-task implementation plan with TDD steps
+- Initialized git repository with 2 commits
+
+## Follow-Up Items
+
+- Execute the implementation plan (15 tasks, starting with project scaffolding)
+- Execution options: subagent-driven (this session) or parallel session with executing-plans skill
