1. Problem Description & System Functionality

Modern households, individuals, and small teams struggle to track scattered recurring commitments:

Expired Renewals: Auto-renewing insurance policies, passports, vehicle registrations, and software licenses that expire without advance warning.
Neglected Maintenance: Routine servicing for vehicles (oil changes, tire rotations), HVAC filter replacements, and home appliances that cause costly damages when overlooked.
Lost Warranties: Expiring electronics and appliance warranties where proof-of-coverage and expiration dates are lost across scattered receipts.
Lack of Shared Responsibility: Roommates, couples, and family members duplicate purchases or miss shared deadlines because tracking lives in fragmented personal notes.

Expected Behavior & Core Capabilities

Multi-User Authentication: Secure user registration, password hashing (bcrypt), and stateless JWT token authorization.
Three Core Lifecycle Types:
- Renewals: Contract end-dates, policy renewals, membership expirations.
- Maintenance: Recurring check-ups, vehicle inspections, home upkeep.
- Warranties: Hardware purchase dates, coverage limits, warranty expirations.
Shared Collaborative Groups: Users can create groups (e.g., "Family Home", "Apartment 4B"), invite members by email, and collaborate on shared lifecycle items. Items remain with the group when members leave.
Action Summaries & Reminders Engine: Automatically detects items due within 30 days and overdue items, rendering an instant action dashboard with urgent priority sorting.
Scheduled Morning Digest Simulator: Simulates daily 8:00 AM notification digests delivering upcoming deadlines to users and group members.

3. AI-Assisted Development Workflow

The project followed a disciplined AI-native lifecycle using interactive agents (Antigravity, Claude Code, Cursor) and headless operational loops:

Ideation to Specification:
- Socratic brainstorming produced product-spec.md and _docs/plan.md.
- Decomposed into atomic tasks in backlog.md and _docs/tasks.md.
Frontend Prototype with Mock Client:
- Scaffolded interactive React 19 UI in frontend/ with centralized mock services layer (src/services/api.ts).
API Contract Freeze & Backend Implementation:
- Reverse-engineered and frozen into contracts/openapi.yaml.
- Implemented FastAPI backend in backend/ with in-memory fallback, then migrated to PostgreSQL.
Containerization & Local Kubernetes:
- Dockerized multi-app architecture (docker-compose.yaml).
- Packaged declarative Kind Kubernetes manifests with PersistentVolumeClaims in k8s/.
Observability & Autonomous Incident Response:
- OpenTelemetry Collector, Prometheus, Loki, Tempo, Grafana in observability/.
- Autonomous on-call responder in on-call-engineer/ with code-enforced autonomy policy (autonomy-policy.json).

Complete prompt transcripts, context injection strategies, and human verification gates are documented in docs/ai-tools-usage-and-review.md.

4. Quick Start (Development Mode)

Run the full stack with hot reloading (zero host runtime dependencies required, powered entirely by Docker):

# Start full development cluster (PostgreSQL on :5434, Backend on :8003, Frontend on :3003)
make up

# Verify container status
make ps

# Stream logs
make logs

# Tear down containers
make down

Access endpoints:

Web Application UI: http://localhost:3003
API Health Check: http://localhost:8003/health
Interactive OpenAPI / Swagger UI: http://localhost:8003/docs
Interactive ReDoc Documentation: http://localhost:8003/redoc

5. Local Kubernetes Deployment with Kind

Deploy the entire stack to a local Kubernetes cluster using Kind (Kubernetes in Docker):

# 1. Create a local Kind cluster
make kind-up

# 2. Build local images and load them into the Kind cluster
make kind-load

# 3. Apply declarative manifests (PostgreSQL PVC + Backend + Caddy Gateway)
make kind-deploy

# 4. Wait for pod readiness and verify rollout status
make kind-verify

# 5. Tear down Kind cluster when finished
make kind-down

For manifest specifications and port forwarding instructions, see k8s/README.md.

6. Production Mode (Caddy Reverse Proxy)

Test the unified production build locally on port 8088 (single port, Caddy reverse-proxying API & static SPA):

# Build and start production stack
make prod-up

# Verify health via reverse proxy
curl -f http://localhost:8088/health

# Stop production stack
make prod-down

7. Testing & Quality Verification

All verification commands execute in isolated container environments:

# Run full test suite (Backend unit + integration, Frontend Vitest, E2E Playwright)
make test

# Run backend tests only (FastAPI unit tests)
make test-backend

# Run PostgreSQL integration tests (multi-user collaboration, DB transactions)
make test-integration

# Run frontend unit tests (Vitest)
make test-frontend

# Run frontend static typecheck & lint
make lint

# Run Playwright E2E browser tests (17 multi-user journeys)
make test-e2e

8. Observability Infrastructure

Personal Lifecycle Tracker includes a decoupled, containerized observability stack in observability/ featuring OpenTelemetry Collector, Prometheus, Loki, Tempo, and Grafana:

# Start observability stack
make obs-up

# Check container status
make obs-ps

# View live telemetry logs
make obs-logs

# Stop observability stack
make obs-down

Grafana Dashboards: http://localhost:3004 (admin / admin)
Prometheus UI: http://localhost:9091
OTel Collector OTLP HTTP Endpoint: http://localhost:4328
Tempo Trace Ingestion: http://localhost:3201

Detailed metrics, logs, and trace pipelines are documented in observability/README.md and _docs/telemetry.md.

9. On-Call Engineer & Autonomous Incident Response

An autonomous monitoring and incident remediation pipeline under on-call-engineer/:

Alert Poller (on-call-engineer/poll-alerts.py): Continuously polls Prometheus alert rules every minute.
Headless Agent Dispatch: Normalizes alerts into payload-schema.json and wakes up a headless coding agent.
Code-Enforced Autonomy: Permissions are enforced via autonomy-policy.json and authorize-action.
Incident Diagnosis & Runbooks: See ops/diagnosis.md and ops/runbook.md.

# Run continuous alert poller
make on-call-poll

# Run verification suite proving alert detection, prompt rendering, and agent dispatch
make on-call-verify

10. Cloud Infrastructure & Environments (Dev & Production)

We maintain two independent copies of our infrastructure across Render and AWS:

Development (dev): Isolated non-overlapping VPC networks (10.1.0.0/16) and free-tier plans.
Production (production): A second, independent copy of the infrastructure provisioned for high availability (10.0.0.0/16 VPC).

Cloud Platform	Dev Environment	Production Copy	Architecture
Render	`render.yaml`	`render.prod.yaml`	Managed PostgreSQL + FastAPI + React/Caddy
Render (Terraform)	`terraform/render/`	`terraform/render-prod/`	Declarative IaC via Render Terraform Provider
AWS (Terraform)	`terraform/aws/` (`10.1.0.0/16`)	`terraform/aws-prod/` (`10.0.0.0/16`)	EC2 (`t3.micro`/Free Tier) + Elastic IP + SSM
AWS (CloudFormation)	`cloudformation/aws-serverless-lambda.yaml`	`cloudformation/aws-serverless-lambda-prod.yaml`	1-Click AWS Serverless Stack (Lambda + S3 + CloudFront + OTel)

11. CI/CD Pipeline & Promotion Workflow

The automated GitHub Actions workflow (.github/workflows/ci.yml) provides test-gated delivery structured into two distinct stages:

Parallel Unit Tests: Backend (FastAPI Pytest) and Frontend (TypeScript lint + Vitest) run concurrently.
Docker Compose Integration & E2E: Builds the full stack, starts PostgreSQL, backend, and frontend containers, runs 27 integration tests, and executes 17 Playwright E2E browser journeys.
Stage 1 (Build): Compiles backend and frontend container images, tags each image using the YYYYMMDD-HHMMSS-shortsha pattern (e.g. 20260818-163457-83242da), and pushes them to Amazon ECR.
Stage 2 (Deploy): Pulls the pre-built image artifacts from Amazon ECR and serves them via Docker Compose (docker compose -f docker-compose.prod.yml up -d --no-build), completely eliminating image building during deployment.
Keyless Cloud Authentication (GitHub OIDC): Uses GitHub OIDC (id-token: write) to assume an AWS IAM role (terraform/aws/oidc.tf) to authenticate with ECR and AWS SSM.

Dev-to-Production Promotion Workflow

The manual workflow (.github/workflows/promote-dev-to-prod.yml) promotes verified dev versions to main:

Runs conflict and regression test gates.
Pulls the currently deployed dev image from Amazon ECR.
Promotes image tags (vX.Y.Z, prod-latest), pushes to ECR, and serves on production without building from source.
Polls live production healthcheck until HTTP 200 is confirmed.
