`multipleOf` is not part of the Gemini/antigravity OpenAPI 3.0 schema subset, so
leaving it in function_declaration parameters triggered a hard upstream 400
("Unknown name multipleOf"). Add it to GEMINI_UNSUPPORTED_SCHEMA_KEYS so it is
stripped at every schema level; minimum/maximum stay (Gemini accepts them).

…rip, parseAutoConfig leaf, cline envelope (#264) Bundles four upstream translator/SSE fixes into the fork: - fix(translator/kiro): wrap system-origin content in <system-reminder> tags before merging into the Kiro/CodeWhisperer user message, so the system prompt no longer leaks as raw user text (diegosouzapw#6053). - fix(translator/gemini): strip `multipleOf` from antigravity/gemini tool schemas at every level (top-level, nested, array items) — Gemini's OpenAPI 3.0 subset rejects it with a hard 400 (diegosouzapw#6052). - refactor(sse): extract the pure `parseAutoConfig` leaf from combo.ts into open-sse/services/combo/autoConfig.ts (diegosouzapw#6049). - fix(sse/cline): unwrap the Cline non-streaming response envelope so a content array of Anthropic-style text blocks is not misclassified as 502 empty_choices (diegosouzapw#6046). diegosouzapw#6002 (autoCombo fitness-source stabilize) is already on fork main via diegosouzapw#5890 — not re-applied here.

Summary
multipleOfnumeric constraint failed with a hard upstream400:Invalid JSON payload received. Unknown name "multipleOf" at 'request.tools[0].function_declarations[...]'.multipleOfis not part of the Gemini/antigravity OpenAPI 3.0 schema subset and was not inGEMINI_UNSUPPORTED_SCHEMA_KEYS, socleanJSONSchemaForAntigravityleft it in the payload.Root cause
GEMINI_UNSUPPORTED_SCHEMA_KEYS(inopen-sse/translator/helpers/geminiHelper.ts) lists the JSON-Schema keywords Gemini rejects, but omittedmultipleOf. Any tool that declared it on a numeric property survived schema cleaning and reached the upstream verbatim.Fix
Add
"multipleOf"to the set.removeUnsupportedKeywordsalready recurses into nested objects and arrayitems, so it is now stripped at every level.minimum/maximumare accepted by Gemini and remain untouched.Attribution
Thanks to @abil0321 for the original report.
