Hello PHP-FIG members,

I wanted to share a comprehensive, 100% open-source ecosystem that serves as a strict, production-grade implementation of multiple PSR standards, developed entirely as a solo project: Waffle-Commons (https://github.com/waffle-commons).

Waffle is built on a radical architectural invariant: concrete components must never depend on each other, only on abstract PSR interfaces and a centralized contracts layer. Across 16 standalone packages, I have successfully composed:

PSR-7 (HTTP Messages) & PSR-17 (Factories) via waffle-commons/http
PSR-15 (Middleware & Request Handlers) via waffle-commons/pipeline
PSR-11 (Container) via waffle-commons/container
PSR-14 (Event Dispatcher) via waffle-commons/event-dispatcher
PSR-3 (Logging) via waffle-commons/log
PSR-6 & PSR-16 (Caching) via waffle-commons/cache
PSR-18 (HTTP Client) via waffle-commons/http-client

This entire stack executes within a long-running, resident-memory environment (FrankenPHP Worker Mode). This constraints-driven runtime provided an excellent testing ground for exploring how stateful vs stateless PSR implementations behave over thousands of concurrent persistent loops, achieving a verified zero memory drift (ΔM = 0) thanks to automated container resets via a request-bound ResettableInterface loop (currently in progress for the next release).

I would be honored to share my data and architectural feedback with the PHP-FIG community regarding PSR interoperability, connection pooling, and boundary enforcement in modern resident-memory runtimes.

Best regards,
