Milestone v0.9.0 — Web-Interface (Dashboard & Service Control)

Target: v0.9.0 — Real-time status dashboard, service control via DB + nudge

Status: ⏳ Planned

References: ADR-0003, ADR-0017, ADR-0019, ADR-0021, VISION.md, ROADMAP.md

User Stories: Web-Interface Stories

Overview

The Web-Interface replaces the web-mock dev UI with a production-grade dashboard built on FastAPI, Jinja2, htmx, Alpine.js, TailwindCSS/DaisyUI, ECharts, and WaveSurfer.js (ADR-0003, ADR-0021).

Key Capabilities

  • Real-time service status via Redis Read+Subscribe pattern (ADR-0017)
  • Service control: enable/disable Tier-2 singletons via managed_services table + nudge
  • Configuration editor for system_config values
  • Recording browser with audio playback (WaveSurfer.js)
  • Detection timeline with species visualizations (ECharts)

Prerequisites

Milestone Feature
v0.5.0 Processor (Indexer + Janitor)
v0.6.0 Uploader (FLAC compression, remote sync)
v0.7.0 Gateway (Caddy reverse proxy, HTTPS)
v0.8.0 BirdNET (On-device Avian Inference)

Deferred Items from Earlier Milestones

managed_services Table Seeding & Reconciliation (from v0.5.0 Phase 5)

Context: v0.5.0 originally planned seeding processor into a service registry table. This was deferred because:

  1. The managed_services table did not yet exist — lifecycle toggles were temporarily stored as enabled: bool inside system_config JSONB (ADR-0029).
  2. The Controller Reconciler derives desired state from devices + microphone_profiles (for Recorders) and compose.yml dependencies (for Tier 1 services like Processor).
  3. Seeding rows without a consumer is dead code.

v0.9.0 is the right milestone because the Web-Interface is the first consumer: it reads managed_services.enabled to show toggle switches, and writes enabled=false + publishes a nudge to disable Tier-2 services (ADR-0017).

Scope: managed_services tracks exclusively Tier-2 singletons (BirdNET, BatDetect, Weather). Tier-1 services (Processor, Controller) are managed externally via Compose and are NOT tracked in this table.

See: ADR-0017 §2 "Desired State → Database"

Tasks

  • [ ] Implement ManagedServiceSeeder in Controller seeder (if not already done in v0.8.0):
  • Seed Tier 2 singletons: birdnet (enabled=true), later batdetect, weather
  • Tier 1 services and multi-instance Tier 2 (Recorder) are NOT seeded here
  • [ ] Web-Interface: render managed_services rows as toggle switches in the admin panel
  • [ ] Web-Interface: toggle writes enabled to managed_services + PUBLISH silvasonic:nudge "reconcile"

Tests

  • [ ] Unit: test_managed_service_seeder — seeds expected Tier-2 rows
  • [ ] Unit: test_reconciler_reads_managed_services — enabled=false → stops container
  • [ ] Integration: test_controller_seeds_managed_services — fresh DB contains expected rows
  • [ ] E2E: test_toggle_service_via_ui — Playwright: click toggle → service stops → heartbeat disappears

Phase 1: Service Architecture

Goal: Create the web service following the Service Blueprint, replacing web-mock.

Tasks

  • [ ] Scaffold services/web/ following the Service Blueprint
  • [ ] Migrate relevant web-mock functionality
  • [ ] FastAPI + Jinja2 + htmx + Alpine.js stack (ADR-0003)
  • [ ] TailwindCSS v4 + DaisyUI v5 build pipeline (ADR-0021)
  • [ ] SSE endpoint for real-time Redis status updates
  • [ ] Compose integration with Gateway dependency

Phase 2: Dashboard & Status

Goal: Real-time service status dashboard using Read+Subscribe pattern.

Tasks

  • [ ] Dashboard page: service cards with live health status (Redis heartbeats)
  • [ ] System overview: disk usage, CPU, memory (from heartbeat meta.resources)
  • [ ] Recording statistics: total indexed, pending analysis, storage used
  • [ ] Service control toggles (requires managed_services seeding above)

Phase 3: Configuration & Settings

Goal: Operator-facing configuration editor for system_config values.

Tasks

  • [ ] Settings page: form-based editing of system_config JSONB values
  • [ ] Validation against Pydantic schemas before DB write
  • [ ] Nudge on save → Controller restarts affected service
  • [ ] User management: password change, RBAC (admin/viewer)

Phase 4: Recording Browser & Audio

Goal: Browse, filter, and playback recorded audio segments.

Tasks

  • [ ] Recording list with sort/filter (time, sensor, duration, status)
  • [ ] Audio player using WaveSurfer.js v7 (ADR-0021)
  • [ ] Spectrogram visualization
  • [ ] Detection overlay on waveform (using BirdNET results)

Phase 5: Visualization & Charts

Goal: ECharts-based detection timeline and species statistics.

Tasks

  • [ ] Detection timeline: species activity over time
  • [ ] Species frequency chart: top-N detected species
  • [ ] Environmental correlation: detections vs. weather data (when available)

Out of Scope (Deferred)

Item Target Version
Multi-station central dashboard post-v1.0.0
Live Opus audio stream (Icecast embed) v1.1.0
Mobile-optimized responsive layout post-v1.0.0
Alert/notification system post-v1.0.0

Note: The web-mock service remains available as a dev/debug tool alongside the production web service until v1.0.0 stabilization.
