## role
Archive of design documents, specifications, and implementation records for a container monitoring and notification system delivered through three stacked pull requests.
## files
- .openspec.yaml | Defines an OpenSpec project specification for a container monitoring and notification system
- apply-pr1.md | Documents the implementation of a backend monitoring and notification system for container instances, including database migrations, SQLAlchemy models, event bus, health monitoring, SSE streaming, lifecycle hooks, structured logging, and unit tests. | dep: Alembic, SQLAlchemy, asyncio, FastAPI, uvicorn, pytest, ruff, Docker, JSON
- apply-pr2.md | Documents a completed frontend pull request implementing real-time container monitoring and notifications via Server-Sent Events, custom toast system, and status badge updates | dep: React, EventSource, Vitest, TypeScript, ESLint, CSS
- apply-pr3.md | Documents the completion status, changed files, implementation summary, and quality gate results for PR-3 which integrated and polished container monitoring and notification features.
- apply-progress.md | Documents TDD-driven implementation progress for a container monitoring and notification system across backend (Python/FastAPI) and frontend (React/TypeScript) PRs, including architecture decisions, test evidence, and deviations from design. | dep: FastAPI, SQLAlchemy, Alembic, pytest, React, TypeScript, Vitest, EventSource, SSE, asyncio, inspect, collections.abc
- design.md | Design document for a container monitoring and notification system using pub/sub events, health monitoring, and Server-Sent Events to push real-time container status updates to a frontend toast notification system. | dep: FastAPI, SQLAlchemy, Alembic, asyncio, Docker, SSE/EventSource, sonner, React/TypeScript, JSON logging
- explore.md | Exploratory analysis document identifying gaps in container monitoring, logging, and notifications for a Docker-based tool instance management system, and recommending an SSE-based real-time event architecture. | dep: FastAPI, Docker CLI, docker-compose, SQLAlchemy, cloudflared, axios, asyncio, TerminalManager
- proposal.md | A software design proposal for implementing a real-time container monitoring and notification system with SSE-based push updates, health monitoring, and audit logging. | dep: FastAPI, Docker, asyncio, SSE/StreamingResponse, PostgreSQL, JSON logging, frontend toast component (sonner or custom), WebSocket (existing terminal), Docker CLI/shell-out patterns
- spec.md | Defines a container monitoring and notification system using an in-memory event bus, background health monitoring, SSE streaming, and real-time frontend notifications with persistent audit logging. | dep: asyncio, PostgreSQL, Docker CLI, HTTP/tunnel probes, SSE (Server-Sent Events), JWT/cookie authentication, JSON logging
- tasks.md | Defines a structured software design document (SDD) for building a container monitoring and notification system across 3 stacked PRs, detailing backend infrastructure (database, event bus, SSE, health monitoring) and frontend UI (SSE hook, toasts, badge updates) with specific tasks, acceptance criteria, and dependencies. | dep: FastAPI, SQLAlchemy, Alembic, Docker, asyncio, SSE/EventSource, React, sonner, pytest, uvicorn, contextvars, TypedDict
## arch
Event-driven architecture using pub/sub in-memory event bus with SSE streaming for real-time frontend updates, TDD-driven 3-PR stacked delivery (backend infrastructure → frontend UI → integration/polish), health monitoring with lifecycle hooks, structured logging, and persistent audit trail.
