v1.125.2

[1.125.2] — 2026-07-22

Fixed

• Deep research over Gemini: HTTP 502 (MALFORMED_FUNCTION_CALL) (#145, contributed by @Alien10140) — the live /api/deep prompt told the model to "Use WebFetch / WebSearch" and to save the brief to a file, but headless API providers have no tool channel; Gemini answered with a function call instead of text, surfacing as an empty HTTP 502. buildDeepPrompt and bundleProjectContext now take a headless flag: live runs (Anthropic/Gemini/fallback cascade) get a no-tools prompt that writes the brief from the inlined context, while the copy-paste prompt for Claude Code keeps its tool instructions. +1 test in tests/critical-fixes.test.mjs.

Changed

• Gemini defaults bumped past the deprecated gemini-2.0-flash (#144, contributed by @Alien10140) — the Config dropdown, the server fallback in gemini.mjs (which silently disagreed with the hint), the OpenRouter fallback chain, config.geminiModelHint ×17 and the help guide ×17 now all name gemini-3.6-flash. The new drift gate tests/gemini-default-model.test.mjs (+5 tests) pins every surface to the same literal — the suite is now 1957 tests.
