From d3e0be8a7372dfc076817e4ccc651485cd4b0b94 Mon Sep 17 00:00:00 2001 From: Minxi Hou Date: Thu, 24 Sep 2026 15:45:59 -0400 Subject: [PATCH 1/7] refactor(sse): split handleChatCore into four response-path leaves MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Re-extraction of #13065 onto the current release/v3.8.51 tip (a41ded27cc). Each leaf is lifted out of handleChatCore unchanged apart from imports/exports and the deps/carry wiring, so every leaf diffs empty against the tip implementation except the wiring: - executeProviderRequest.ts — one provider send (admission, body preparation, executor call, retry ladder) - nonStreamingResponse.ts — the !stream leg - streamingResponse.ts — the stream leg up to readiness - streamingTail.ts — readiness, translation pipeline, tail finalization While replaying, the 18 upstream hunks that landed inside the lifted regions were folded into the leaves so behaviour stays identical to the tip: getExecutorClientHeaders() call sites, metered-budget cost wrapping, the stream-readiness fallback hook, formatted FLUSH_EMPTY_RETRY verdict logging, captureStreamReasoningForReplay, videoTranscriptSensitive flags, and the connection-id provenance fields on the streaming response headers. The hard-lease inventory guard moves its FLUSH_EMPTY_RETRY expectation to the leaf's new home.

The binding in the leaf was never read, so lint flagged it. The barrel still passes userAgent to the header builder, the format resolver and the bypass handler.
