Normalize compact stream flag

[rabesss]

Summary

• allow /v1/responses/compact requests that include stream: true
• normalize compact requests by removing stream before dispatching the non-streaming compact executor path
• update the compact handler test to assert the request executes and the executor payload no longer includes stream

Root Cause

The compact handler rejected stream: true before provider execution, which produced the first compact stream parity blocker against the shim path. The shim-compatible behavior is to treat compact as a JSON compact response and ignore the stream flag.

Validation

GitHub Actions unavailable due to exhausted Actions minutes; validation is local/manual only.

Local checks run:

• go test ./sdk/api/handlers/openai -run 'TestOpenAIResponsesCompact'
• go build -o test-output ./cmd/server then removed test-output
• node scripts/ci/protocol-parity-harness.js --plan
• node --test scripts/ci/protocol-parity-harness.test.js
• git diff --check
• focused secret scan over touched files

Live redacted parity note: the latest redacted report was inspected and identifies compact_stream_true:cline-pass-glm-5-2 as the first hard-gate blocker. A patched live redacted compare still needs to be run after deploying or launching this CLIProxyAPI build locally.

Code Review

This pull request modifies the OpenAI responses compact handler to normalize requests containing the "stream" parameter instead of rejecting them with a 400 Bad Request. Specifically, it removes the check that rejects "stream": true and instead deletes the "stream" field from the payload if it exists. The corresponding unit tests have been updated to verify this normalization behavior. I have no feedback to provide.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

Closing this as diagnostic evidence only. The PR proved the Codex compact stream: true direct-bypass gap, but we are not going to maintain Codex-specific Responses compatibility inside CLIProxyAPI. CLIProxyAPI should remain an upstream/provider aggregator; the maintained Codex compatibility route belongs in codex-shim. Do not merge this PR.
