Summary

• fix net/http handler bridge by injecting *http.Request and http.ResponseWriter into context and resolving them inside libContext.InitContext
• add net/http bridge regression tests to validate parser-backed response writing
• add libChi helper package for route param extraction and parser initialization
• add chi route-param tests (single, multiple, missing)
• add sqlc-style integration test using *sql.DB + sqlmock for chi + net/http flow
• document canonical chi + net/http + sqlc(database/sql) + pgx/stdlib setup in README
• document optional pgx-native track and parity matrix

Validation

• go test ./libNetHttp ./libChi
• go test ./libContext
