Greptile Summary

This PR adds alias support to Hook::param(), allowing a parameter to be matched under one or more alternative names when the canonical key is absent from both $requestParams and $values. The implementation in Base::prepare() correctly prioritises the canonical key and falls back to the first matching alias for both lookup sources.

Confidence Score: 5/5

Safe to merge — the alias resolution logic is correct and backward-compatible.

No P0 or P1 issues found. The alias resolution correctly handles canonical-key precedence, empty alias lists, and lookup in both $requestParams and $values. The previously flagged test-coverage gap is a P2 concern that does not affect correctness.

No files require special attention.

Important Files Changed

Filename	Overview
src/Servers/Hook.php	Adds optional aliases parameter (default []) to param() method and stores it in the params array — clean, backward-compatible addition.
src/Servers/Base.php	Implements alias resolution for both $requestParams and $values in prepare(); canonical key takes precedence when present, first matching alias used otherwise. Logic is correct.
tests/Servers/Unit/HookTest.php	Adds two unit tests verifying alias storage in Hook::param(); integration tests for actual resolution in Base::prepare() are absent (previously flagged).
