P0 fixes: - ModelError.Is(): use exact matching instead of substring contains() - shouldClearStickySession: add context param for cancellation/tracing P1 fixes: - TODO stubs: return 501 Not Implemented errors - validateInstanceSignature: deduplicate to shared validateCodeSignature() - Error messages: standardize to English only - http.go: remove pseudo if-else with duplicate branches
