The first revision compared GetInboundEndpoint(c) against EndpointResponses
("/v1/responses"). NormalizeInboundEndpoint only recognizes paths that
contain the literal "/v1/responses" substring, but the project actually
registers six /responses routes — three of which (top-level
r.POST("/responses", ...) and codexDirect's "/backend-api/codex/responses")
have FullPath values without the "/v1" prefix and therefore fall through
to the default branch.
Codex CLI users targeting the bare /responses route at the production
deployment (observed 2026-05-24 ~11:05 UTC, user 16) never reached the
new writeResponsesFailedSSE path: the endpoint check was false, the
legacy `event: error` frame fired, and the strict SDK kept reporting
"stream closed before response.completed".
Replace the strict equality check with inboundIsResponses(c), which
uses suffix detection on FullPath (falling back to URL.Path when
FullPath is empty in test fixtures) and covers all six route variants:
/v1/responses[/...]
/responses[/...]
/backend-api/codex/responses[/...]
Add test table covering all routes plus negative cases.

When /v1/responses streaming hits the user/account concurrency wait, the
wait loop sends SSE ping comments to keep the connection alive, which
flushes HTTP 200 + headers. If the wait then times out (or any other
post-flush error fires), handleStreamingAwareError previously emitted a
generic `event: error` frame. Codex CLI requires the stream to end with
a Responses terminal event (response.completed/failed/incomplete/cancelled),
so it reports "stream closed before response.completed" and the user-facing
rate-limit intent is lost.
This change detects inbound = /v1/responses in both handleStreamingAwareError
implementations and emits a protocol-compliant response.failed event whose
field set mirrors apicompat.makeResponsesCompletedEvent
(id/object/model/status/output/error). The synthetic id reuses
ctxkey.RequestID so client errors can be grepped against server logs.
sequence_number is intentionally omitted to preserve monotonicity on streams
that already emitted real events.
Other inbound endpoints (/v1/chat/completions, /v1/messages) keep their
legacy formats untouched.

- Export ApplyBedrockCCCompat() in GatewayService, called after channel
model mapping to ensure mapped model ID is used for Opus 4.7+ detection
- Add sanitizeBedrockCCFields(): remove service_tier/interface_geo/
context_management, inject max_tokens/anthropic_version defaults
- Add sanitizeBedrockCCBetaTokens(): filter anthropic_beta to keep only
Bedrock-supported tokens, reusing autoInjectBedrockBetaTokens and
filterBedrockBetaTokens for consistent rules
- Remove unsupported beta tokens (interleaved-thinking, context-management)
from whitelist based on AWS official docs
- Simplify IsBedrockCCCompatEnabled() to check boolean toggle directly,
applying CC compat to all accounts regardless of platform
- Add unit tests for IsBedrockCCCompatEnabled (8 cases),
sanitizeBedrockCCFields (8 cases), sanitizeBedrockCCBetaTokens (7 cases)
- Update bedrock beta policy tests for removed auto-injection
The refresh button had no effect because two independent gates blocked
the Codex probe:
1. isOpenAICodexSnapshotStale returned false for non-WS-v2 accounts even
when data was stale — this is correct for background auto-refresh (Codex
quota is only auto-tracked for Codex CLI / WS v2 accounts), so this
behavior is preserved.
2. shouldProbeOpenAICodexSnapshot had a 10-min in-memory rate limit with
no bypass for explicit user requests.
Fix: add a force parameter threaded from handler → GetUsage → getOpenAIUsage
→ shouldProbeOpenAICodexSnapshot. When force=true (manual refresh button),
both gates are bypassed and the probe always runs. Background auto-loads
continue to respect the original WS v2 logic and 10-min rate limit.
