# Work Log — May 2026

## Summary
Session focused on auth system architecture, dashboard redesign, and audio track inspector. Multiple iterations on auth approach; settled on simplified local-account model with RBAC. Dashboard rebuilt as control-room status board. Audio tab completed with full metering and fader controls.

## Auth System Work

### Commits
- `002e5ac` — auth: top-to-bottom rework — local accounts, RBAC + client tag, audit log, env-bootstrap
- `d1f9557` — auth: park login flow — circle back
- `9726dbb` — Revert "auth: top-to-bottom rework..."
- `4172b0d` — rip out entire auth/login flow

### What Happened
Attempted comprehensive auth rewrite including:
- Local user account system with bcrypt hashing
- Role-based access control (admin/editor/viewer)
- Client tagging for audit trails
- Environment-based bootstrap (AUTH_ENABLED flag)
- Session management with PostgreSQL backing

**Decision**: Reverted entire auth work. Reason: complexity vs. current product stage. System was over-engineered for self-hosted use case where auth is optional.

**Current State**: Auth disabled by default (AUTH_ENABLED=false). When enabled, system returns synthetic /auth/me endpoint. No persistent user management yet.

### Related Fixes
- `cfcbec0` — fix(auth): make AUTH_ENABLED=true workable end-to-end
- `e71c330` — fix(auth): remove manual session.save() — was suppressing Set-Cookie header
- `65684aa` — fix(auth): ensure sessions table exists + log session.save errors

## Dashboard Redesign

### Commits
- `a48e1d9` — dashboard: rebuild as control-room status board (on air / up next / attention / work)
- `e5e0656` — dashboard: redesign stat cards, compress header, improve density
- `5de1e3d` — dashboard: add dense stat cards, cluster bars, job rows, sparkline fixes
- `48d54a3` — dashboard: add missing dash-* CSS classes; cluster: add stat-row/stat-card CSS

### What Changed
Transformed dashboard from generic metrics view to broadcast control-room interface:
- **On Air** section: live stream status, bitrate, duration
- **Up Next** section: queued clips/segments
- **Attention** section: warnings, errors, resource alerts
- **Work** section: active jobs, encoding progress

Added visual components:
- Dense stat cards with icon + value + trend
- Cluster health bars (CPU, memory, disk per node)
- Job progress rows with ETA
- Sparkline charts for trend visualization

CSS infrastructure added for consistent spacing/sizing across dashboard components.

## Audio Tab Implementation

### Commit
- `c48c7e6` — feat(audio-tab): full audio track inspector with meters, mute/solo, faders

### Features
- Per-track audio meters (VU-style, real-time)
- Mute/solo buttons per track
- Fader controls (0-100 dB range)
- Master output meter
- Track naming/labeling
- Visual feedback for clipping/peaks

## Other Work

### Storage & Admin
- `64d739b` — feat(admin): unified Storage settings page with mount/bucket health diagnostics
- `a44d8bd` — feat(admin): live video-presence indicators on cluster DeckLink ports

### Player & Streaming
- `a86c1c7` — fix(player): stitch S3 ranges around RustFS empty-body bug (#143)
- `d257a19` — fix(player): buffer indicator + 416 instead of 500 on out-of-range S3
- `37247fd` — fix(video): direct S3 signed URL for streaming + proxy bitrate 1.5Mbps
- `e4d4c00` — feat(proxy): VBR 500k-1M encoding for proxy generation

### Cluster & Hardware
- `55ff2e7` — feat(cluster): full hardware breakdown per node
- `5ff507b` — fix(node-agent): use nsenter to run nvidia-smi in host mount namespace
- `558c18e` — fix(node-agent): detect GPUs via docker run --gpus all ubuntu:22.04
- `a6f045b` — fix(node-agent): probe GPU via Docker API async at startup, cache result

### Release & Cleanup
- `04ce096` — chore: 1.2 ship-prep sweep — close 38 issues
- `f0f6156` — release: add v1.1.0 ZXP artifact (Growing tab + visual system alignment)

## Blockers / Open Questions

### Auth System
- **Decision needed**: Should auth be mandatory for production? Current design assumes optional.
- **API endpoints missing**: `/users`, `/auth/me`, `/groups` routes not yet implemented in mam-api
- **Frontend expects**: Users list, groups management, role-based UI filtering

### Dashboard
- Real data integration needed (currently mock data)
- Cluster stats endpoint integration
- Job queue polling/WebSocket updates

### Audio
- Backend audio processing pipeline not yet connected
- Metering data source undefined
- Fader changes need routing to encoder

## Next Steps (Recommended)

1. **Clarify auth requirements**: Is user management needed for v1.2? If yes, implement `/users` and `/groups` endpoints.
2. **Connect dashboard to live data**: Wire cluster stats, job queue, stream status to real endpoints.
3. **Audio backend integration**: Define audio processing pipeline and metering data flow.
4. **Testing**: Add integration tests for auth flow, dashboard data binding, audio control.
