Summary

Complete implementation of Milestone M10-Telemetry (0.0.10) — integrating Mosaic Telemetry SDKs into the API, Coordinator, and Web frontend for AI task completion tracking and cost forecasting.

Issues Closed

• #369 — Install @mosaicstack/telemetry-client in API
• #370 — Install mosaicstack-telemetry in Coordinator
• #371 — Track LLM task completions
• #372 — Track orchestrator agent task completions
• #373 — Prediction integration for cost estimation
• #374 — Add telemetry config to docker-compose and .env
• #375 — Frontend token usage and cost dashboard
• #376 — Documentation: Telemetry integration guide

Changes by Component

API (NestJS):

• MosaicTelemetryModule — Global NestJS module wrapping TelemetryClient lifecycle
• MosaicTelemetryService — Injectable service for trackTaskCompletion, getPrediction, eventBuilder
• LlmTelemetryTrackerService — Fire-and-forget LLM completion tracking with cost table
• PredictionService — Pre-task cost/token estimates with 6hr TTL cache
• MosaicTelemetryController — GET /api/telemetry/estimate endpoint

Coordinator (Python/FastAPI):

• TelemetryClient lifecycle in FastAPI lifespan (start_async/stop_async)
• mosaic_telemetry.py — build_task_event helper, create_telemetry_config
• Agent-to-telemetry field mapping in Coordinator and OrchestrationLoop
• Non-blocking _emit_task_telemetry on every task completion

Web (Next.js):

• Usage dashboard page with recharts (line, bar, pie charts)
• Summary cards: tokens, cost, tasks, quality gate pass rate
• Time range selector (7d / 30d / 90d)
• Loading, empty, and error states
• PDA-friendly design throughout

Infrastructure:

• MOSAIC_TELEMETRY_* env vars in .env.example, docker-compose files, swarm configs
• .npmrc for Gitea npm registry, pip.conf for Gitea PyPI registry

Documentation:

• Comprehensive docs/telemetry.md (736 lines)
• README.md link added

Stats

• 46 files changed, 6,319 insertions, 203 deletions
• 9 commits on feature/m10-telemetry
• Tests: 32 (API module) + 69 (LLM tracker) + 175 (LLM service) + 28 (coordinator) + 14 (web) = 318 new tests

Test plan

• All API unit tests pass (pnpm test:api)
• All coordinator tests pass (pytest)
• All web unit tests pass (pnpm test:web)
• Lint clean on all new files
• Telemetry disabled by default (MOSAIC_TELEMETRY_ENABLED=false)

feat(#370): install mosaicstack-telemetry in Coordinator ... 83d0cbe0f1

- Add mosaicstack-telemetry>=0.1.0 to pyproject.toml dependencies
- Configure Gitea PyPI registry via pip.conf (extra-index-url)
- Integrate TelemetryClient in FastAPI lifespan (start_async/stop_async)
