Sample
github.com/go-chi/chi/v5 v5.3.1: Path-modifying middleware in chi like StripSlashes and RedirectSlashes must be registered at router-level via r.Use() before routes, because per-route r.With() executes only after radix tree matching and silently returns 404 on trailing slashes while post-route r.Use() panics loudly.

This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Case
HOW- Goal
- Path-modifying middleware in chi like StripSlashes and RedirectSlashes must be registered at router-level via r.Use() before routes, because per-route r.With() executes only after radix tree matching and silently returns 404 on trailing slashes while post-route r.Use() panics loudly.

Contract
- assert per-route With(StripSlashes) fails with 404 on trailing slash requests because tree matching precedes route middleware
- assert router-level Use(StripSlashes) strips trailing slashes and serves 200 before tree matching
- assert per-route With(RedirectSlashes) fails with 404 while router-level Use(RedirectSlashes) returns 301
- assert calling Use after route registration panics with frozen middleware chain error
