Phase 9 — Developer / Progress Document¶

Purpose¶

Phase 9 focused on production readiness and trust boundaries: deploying safely, tightening authorization scaffolding, and ensuring the app behaves predictably under production settings.

Deployment¶

Added deployment-oriented validation using Django’s check --deploy with production-style environment variables.
Documented Railway runtime expectations and environment configuration in docs/deployment.md.
Standardized the base template to reference local static assets (core/app.css, core/app.js) for predictable production serving.

Trust Closure and Permission Scoping¶

Introduced default auth groups (player, admin) and assigned model permissions during post_migrate.
Ensured new users join the player group automatically on signup.
Used permissions as a coarse capability layer while preserving per-player scoping as the primary isolation mechanism.

Cleanup Outcomes¶

Consolidated “production boot” expectations into reproducible checks and tests.
Reduced reliance on environment-specific behavior by making host and origin handling explicit in production configuration.

Notes and Limitations¶

Group permissions do not replace per-player queryset scoping; both are required for safe behavior.
Production checks validate configuration but do not validate data correctness or analysis results.
