the route-info cache comparisons so req is checked by identity against each
cache accessor. No other changes are needed.

These assertions now compare request contents rather than request identity. A cache regression that returns newly allocated but equivalent requests would still pass, so the test no longer verifies reuse of the cached request instance. Use require.Same for both comparisons. This is non-blocking, but it reduces protection for the cache-reuse contract.
Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!
Artifacts
Focused Go source proving equality and identity differ for cached request pointers
- Authored and executed Go regression source constructs two distinct pointers with equal values and checks testify equality behavior; it is the executable proof source.
Base-to-current semantic canonical test diff
- Captured `git diff HEAD^ HEAD` for the target test and shows direct pointer comparisons replaced by `require.Equal`; the identity assertions were removed.
Focused Go regression check output
- Captured execution of the authored focused check, which logged Equal passing and Same rejecting the same distinct value-equal pointers; the regression is demonstrated.
Current semantic cache test output
- Captured execution of the current targeted core test, which passes under its weakened equality-only assertions; the test no longer guards pointer reuse.

require.Equal accepts a replacement breaker when its fields match the original breaker. That means this test no longer detects replacement of the retained busy or open breaker instance; the same issue affects the other reuse and provider-sharing equality checks in this file. Use require.Same where the contract is to retain or reuse the exact breaker. This is non-blocking, but it weakens regression coverage for circuit-breaker state retention.
Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!
Artifacts
Focused Go source proving Equal versus Same for distinct breaker pointers
- Authored executable creates two separate breakers with identical state and invokes testify require assertions; it directly tests the asserted contract.
Focused breaker identity assertion execution output
- Executed `go run trex-artifacts/breaker_identity_regression.go` from the repository root; Equal accepted distinct pointers while Same rejected them, confirming the regression.
Base-to-current breaker assertion diff
- Executed Git diff from the repository root comparing the base test contract to current assertions; it shows identity checks replaced by Equal.
Current affected lines and base identity assertions
- Executed numbered source and base assertion extraction; it identifies current lines 34, 35, 71, 163, and 174 and the prior identity assertions.
Affected current breaker tests passing
- Executed the focused internal llmclient breaker test selection; all current tests pass despite the weakened identity checks.

assert.NotNil records a failure but continues running, so each following pointer dereference can panic when parsing returns nil. Use require.NotNil before dereferencing ContextWindow, MaxOutputTokens, and Pricing; the metadata override assertion later in this file and similar converted config tests need the same guard. This is non-blocking, but a regression would produce a panic instead of a focused assertion failure.

Preserve the exact supplied error.
NewInvalidRequestError assigns the supplied error directly to GatewayError.Err. assert.ErrorIs checks only the unwrap chain and can pass when Err stores a wrapper around originalErr. assert.Equal can pass for a distinct equal-valued error.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
