Replaces the busy-wait polling loop in `waitForWasm` with a `borgstmf:ready` event listener.
This eliminates unnecessary CPU usage during initialization and potentially improves latency.
Also updates the `stmf.wasm` binary to ensure it contains the event dispatch logic present in `pkg/wasm/stmf/main.go`.
Fixes a CI build failure by changing `pkg/player/assets.go` to use directory embedding (`//go:embed frontend`) instead of explicit file embedding, which avoids errors when ignored files (like `demo-track.smsg`) are missing in the CI environment.
V3 streaming format enables zero-trust media streaming:
- Content encrypted once with random CEK
- CEK wrapped with time-bound stream keys derived from LTHN hash
- Rolling window: current period + next period always valid
- Keys auto-expire, no revocation needed
Cadence options (platform controls refresh rate):
- daily: 24-hour periods (2026-01-12)
- 12h: Half-day periods (2026-01-12-AM/PM)
- 6h: Quarter-day periods (2026-01-12-00/06/12/18)
- 1h: Hourly periods (2026-01-12-15)
Key derivation: SHA256(LTHN(period:license:fingerprint))
- LTHN is rainbow-table resistant (salt derived from input)
- Only the derived key can decrypt, never transmitted
New files:
- pkg/smsg/stream.go - v3 encryption/decryption
- pkg/smsg/stream_test.go - 17 tests including cadence
WASM v1.3.0:
- BorgSMSG.decryptV3(data, {license, fingerprint})
- getInfo() now returns cadence and keyMethod
- cmd/dapp-fm-app: Native desktop app with WebView (Wails)
- cmd/dapp-fm: CLI binary for HTTP server mode
- pkg/player: Shared player core with Go bindings
Architecture: Go decrypts SMSG content, serves via asset handler.
Frontend calls Go directly via Wails bindings for manifest/license
checks.
