Session Report — Reports/Brain Radio

2026-07-15 23:41 · repo C:/Users/valte/Code/valter · branch main

Summary

Built a self-contained generative lofi/ambient radio player for the CEO reports (a nod to the neuro-acustic-engine), then extended it to the live-brain views (2D + 3D) served single-source — fixing a pre-existing blank-3D-scene bug (a three.js version mismatch) along the way. Finally rebuilt it into a multi-source player: the offline Ambient synth plus YouTube, Spotify, SoundCloud, Deezer, Pandora, and any public-radio stream. Ambient and public radio (SomaFM) were verified playing end-to-end in a real browser; the YouTube and Spotify embeds render with native controls. Tracked as adb TASK-00028.

Timeline

Read the neuro-acustic-engine repo + the two report pages; built reports/radio.js as a floating, theme-aware generative Web-Audio player (moods Focus/Relax/Learn/Deep). Wired the one-line <script src="radio.js"> include into both report generators (build_dashboard.py + the ticket-progress-report skill template) so it survives regeneration.
Verified in a real browser (Playwright over a local HTTP serve): widget renders, plays, visualizer paints real audio, mood switch recolours + persists, theme-aware.
“Same for the live brain”: served the same radio.js single-source via a route in tools/brain-live/server.ts; injected it into the 2D + 3D pages; set data-theme="dark"; wired the 3D [h] hide-UI hotkey to hide the widget for clean OBS capture. Diagnosed + fixed the 3D view rendering blank — 3d-force-graph needs three/webgpu/tsl/examples, which three@0.160 lacks; bumped the importmap to three@0.180. Created TASK-00028.
“Connect to my players”: asked which sources to wire in, then rebuilt into a multi-source player split across three files — orchestrator + Ambient engine + external adapters — and generalised the server route to /radio-*.js. Verified Ambient + SomaFM playing; Spotify + YouTube embeds mount with native controls.

Artifacts produced

File	What it is
`reports/radio.js`	Multi-source player orchestrator + UI: source dropdown, contextual panel, transport, volume, now-playing (Ambient visualizer / spinning-disc). Loads the two sibling modules relative to its own URL, so the single include is unchanged.
`reports/radio-ambient.js`	The self-contained generative lofi/ambient synth (Web Audio, zero network, offline on `file://`) — 4 moods mapping intent→scale/tempo/noise/binaural. Exposes `window.MIARadioAmbient`.
`reports/radio-sources.js`	External source adapters (YouTube IFrame API, Spotify embed API, SoundCloud Widget API, Deezer embed, Pandora link, and a `<audio>` catch-all for any radio/stream URL) + curated presets. Each lazy-loads its 3rd-party API only when used.
`tickets/…/TASK-00028/`	adb ticket tracking the brain-live radio integration + the 3D three.js fix (created this session).

Note: reports/ and tools/ are gitignored (fail-closed allowlist), so these are surfaced by the mtime scan, not git status. They are local workspace artifacts — nothing to commit.

Files edited

File	Change
`tools/brain-live/index-3d.html`	Radio include; `data-theme="dark"`; `[h]` hotkey also toggles the radio; importmap bumped `three@0.160→0.180` + added `three/webgpu`, `three/tsl`, `three/examples/jsm/` (fixes blank 3D scene).
`tools/brain-live/server.ts`	Added a `/radio(-[a-z]+)?.js` route serving `reports/radio*.js` single-source (with a 404 guard) — no duplicate copy.
`tools/brain-live/index.html`	2D view: radio include + `data-theme="dark"`. (Edited early in the session; outside the 8h mtime window.)
`tools/brain-live/README.md`	Documented the ambient radio + the `three@0.180` importmap rationale.
`reports/index.html`	Regenerated via `build_dashboard.py` so it emits the radio include. shared the generator itself was also modified by a concurrent session.
`skills/…/ticket-progress-report/references/report-template.html`	Radio include added to the template (in the skills repo — a separate git repo) so regenerated `ticket-progress.html` keeps it.

Key decisions

Generative Web-Audio, not an external stream, for the base radio — “my own radio” that is fully self-contained and works offline on file://, with no dependencies or accounts.
Single source of truth for the player — one canonical reports/radio.js family, referenced by both report generators and served to the brain via a server route; editing one place changes it everywhere and it survives regeneration.
Fix the pre-existing 3D breakage (three 0.160→0.180) rather than leave the streaming view blank — a small, reversible importmap change that unblocked the exact view the radio targets.
Multi-source = Ambient default + lazy adapters — Ambient stays offline; external APIs load only when picked. Honest capability gating: no visualizer for cross-origin sources (spinning disc instead), no volume slider for Spotify (its embed API has none), YouTube embed made visible (YouTube won’t play a hidden player), Pandora is link-only (no public web API), Spotify full Web Playback SDK deferred (needs the user’s client ID + Premium).
Asked before building the connectors (which services + Spotify depth) — the answer materially changed the build and what could be promised.

Tasks

Task	Status	Note
`TASK-00028` — Add generative lofi/ambient radio to brain-live (2D + 3D) + fix 3D three.js version	backlog	Created this session (feat, P3, owner: valter) as the record; work implemented + partly verified, not committed (paths are gitignored).

Other tasks in the adb board (TASK-00029…00034, etc.) were created by concurrent sessions and are out of scope for this report.

Sources & caveats

Fact sources used this run: git mtime scan adb tasks gstack (stale — only a 2026-07-13 entry) transcript (wrong session).

The auto-selected transcript was a different concurrent session (an Agent-Reach install), and the mtime scan surfaced many files from other active sessions (content-agency, sphere-digest, diary, clips, agent-reach-mcp, other session reports). This report is deliberately scoped to this session’s thread — the radio player and brain-live work — anchored to my own session context plus the radio-related git/mtime facts, and it excludes the concurrent sessions’ artifacts.

Recap reflects available context + git facts; a long/compacted session may omit earlier steps. File lists are derived from git + the mtime scan, not memory. Verified in-browser: Ambient + SomaFM radio playing; Spotify + YouTube embeds render with native controls. NOT runtime-verified this session: SoundCloud, Deezer, Pandora (implemented, following the same patterns), and actual YouTube/Spotify audio (headless test browsers throttle it — the visible embeds’ native controls are the guaranteed path in real Chrome).
