LifeRPG Modernization Roadmap

This roadmap prioritizes work to modernize LifeRPG into a cross-platform, integrations-capable, security-focused habit-tracking "level-up" system.

Prioritization legend:

• Priority: P1 (high), P2 (medium), P3 (low)
• Effort: S (1-3 days), M (1-2 weeks), L (2-6 weeks)

Milestone 1 — Core rewrite & cross-platform skeleton (P1, S → M)

• Goal: Create a maintainable API backend, web frontend, and PWA shell.
• Tasks:
• Scaffold backend API (FastAPI) — Effort: S
• Scaffold React frontend + Vite + PWA manifest — Effort: S
• Add Dockerfiles and docker-compose for local dev — Effort: S
• Add CI skeleton (tests/migrations/smoke) — Effort: S
• Success criteria: repo contains runnable dev skeleton and CI passes basic checks.

Milestone 2 — Data model & persistence (P1, M)

• Goal: Design DB schema and migration strategy.
• Tasks:
• Draft ER: Users, Profiles, Projects, Habits, Logs, Achievements, Integrations, ChangeLog — Effort: S
• Implement migrations + ORM (SQLAlchemy/Alembic) — Effort: M
• Add encrypted backups and export/import — Effort: S
• Success criteria: migrations run and basic entities can be persisted.

Milestone 3 — Auth, security, and infra (P1, M)

• Goal: Secure auth and deployment-ready infra.
• Tasks:
• Implement OAuth2/OIDC login with PKCE (multi-provider, RP-initiated logout, optional signed state JWT, optional claims validation) — Effort: M
• Secure storage for tokens (encrypted at rest) — Effort: M
• Add 2FA (TOTP) and account hardening — Effort: M
• Enforce HTTPS-only cookies in production (COOKIE_SECURE) and HSTS (HSTS_ENABLE)
• OIDC state: support DB-backed or signed JWT (stateless vs. server invalidation)
• Optional audience/issuer validation on ID tokens
• TOTP 2FA and recovery codes
• session_alt cookie flow for admin-assisted 2FA and secure alt-session lookup
• Public read-only tokens for widgets (e.g., status badges)

• Redis-backed rate limiting middleware (fallback in-memory) — Effort: S
• Alembic drift check workflow in CI — Effort: S
• Alerting rules and runbooks — Effort: M
• Redis-down resilient enqueue path (auto inline fallback when queue unreachable) — Effort: S
• Success criteria: actionable dashboards and metrics; basic SLOs visible.

Roadmap timeline (example pace: solo maintainer ~10 hrs/week):

• Month 0 (weeks 0–2): Milestone 1
• Month 1 (weeks 3–6): Milestone 2 + start Milestone 3
• Month 2 (weeks 7–10): Finish Milestone 3
• Month 3–4: Milestone 4
• Month 5: Milestone 5
• Month 6: Milestone 6
• Months 7+: Milestone 7 and polish

Risks & mitigations:

• Third-party API rate limits — use queued workers and backoff.
• OAuth complexity on mobile — use PKCE and server-side token exchange patterns.
• Privacy/regulatory requirements — provide E2EE option and clear privacy policy.
