Backend:
- extract.go: listTags() navigates to volume, runs akaiutil lstags
- extract.go: parseTags() parses tag name/index from lstags output
- serve.go: GET /api/disk/partitions — list partitions on an ISO
- serve.go: GET /api/disk/volumes — list volumes on a partition
- serve.go: GET /api/volume/tags — list tags on a volume
Web UI:
- Tag Viewer section with ISO path input and Browse button
- Partition selector buttons
- Volume grid with click-to-select
- Tag chips with color-coded dots (20-color palette)
Tests:
- 6 parseTags tests (basic, spaces, defaults, no tags, empty, no-type)
- 1 listTags integration test
- 4 API endpoint tests (partitions, missing-ISO, missing-params, tags)
Karpathy: read-only view first — no write operations yet (settagi, clrtagi)
extract.go replaces the bash script with idiomatic Go:
- akaiutil process communication via stdin/stdout pipes
- partition enumeration (df output parsing)
- volume enumeration (dir output parsing per partition)
- sample2wavall per volume with WAV count aggregation
runAkaiutil is a package-level var — tests stub it with canned
output to verify parsing without a real akaiutil binary or ISO.
Removed: findScript(), -tool flag on extract, os/exec from main.go
Kept: extract_wavs.sh as a standalone utility (no longer called)
