Boarded with #11954/#11953/#11952/#11948 in one combined worktree: typecheck:core, check:file-size, check:changelog-integrity, check:complexity, check:cognitive-complexity, check:cycles all green; 85/85 focused tests pass. Confirmed the codex registry entry was missing forceStream: true while every other JSON-only-client provider (cline, clinepass, ghe-copilot, kimi, zed-hosted, chatgpt-web-codex) already has it. Clean reuse of the existing bridge, no Codex-specific response handling needed. Thanks!
* fix(cline): force upstream streaming for Cline/ClinePass (streaming-only API)
Cline's API (api.cline.bot) only implements streaming (streamText). A
non-streaming request returns HTTP 500 "generateText is not implemented" (Claude
models) or HTTP 502 "empty response" (others). Live-verified on the VPS:
stream:true → works (STREAM_OK), stream:false → fails. This is why testing a Cline
model in the dashboard (the test button sends stream:false) failed.
Fix (reuses the existing isClaudeCodeCompatible mechanism, no new handler):
- Flag `cline` and `clinepass` registry entries with `forceStream: true`.
- In chatCore, OR `providerRequiresStreaming` into `upstreamStream` (line 1591)
so the upstream request always streams for these providers, while the client's
original `stream` intent still drives the response format. The existing
non-streaming branch (parseNonStreamingResponseBody) already accumulates the
upstream SSE and converts it back to JSON for stream:false clients — the same
path Claude-Code-compatible providers already use.
Tests (Rule #18): tests/unit/cline-force-stream.test.ts pins the registry flags +
resolveStreamFlag forcing behavior. Live VPS before/after recorded on the PR.
* fix(sse): cline forceStream must stream upstream only, keep client JSON
The #2081 wiring fed providerRequiresStreaming into resolveStreamFlag,
forcing the client-facing stream flag to true for forceStream providers.
That skips the if(!stream) branch that drains a forced upstream SSE and
converts it back to JSON, so a stream:false caller (model-test button,
plain JSON API) got STREAM_EARLY_EOF instead of a JSON body.
Keep providerRequiresStreaming only on upstreamStream (force upstream to
stream); leave the client-facing stream as the client sent it, so
readNonStreamingResponseBody accumulates the SSE into JSON. The promised
handleForcedSSEToJson (#2081 comment) was never implemented — this uses
the existing non-streaming SSE-buffering path (same as isClaudeCodeCompatible).
Live-verified on VPS: cline stream:true worked, stream:false failed.
