Implements MeshVault M1 (issues #6–11): - Four-service Docker Compose stack (nginx, PHP-FPM 8.3, PostgreSQL 17, Node assets) - Slim 4 + PHP-DI routing with escaped PHP views and production/dev error handling - Immutable validated AppConfig with redacted diagnostics - JSON stdout Monolog logging with job-scoped context - Tailwind CSS v4 deterministic locked builds with template scanning - POSIX and PowerShell dev wrappers (up/down/test/lint/assets/watch) - Startup config validation fails before FPM serves as unprivileged www-data - migrate/seed explicitly unavailable until M2 (#12); #10 remains open Verified via clean-start acceptance on remote host (keith@192.168.2.23).
Future HTTP document root
M1 issue #7 adds the PHP front controller; issue #9 adds generated assets in
build/ (ignored by Git). Configure the web server to expose only this directory,
never the repository, credentials or managed library directly. Model downloads
must go through validated application file IDs. This is not yet a runnable site.
