📝 WalkthroughWalkthroughThe resolver now uses an empty string for missing function-call IDs. A new test verifies that Gemini conversation history preserves the matching function call and response. ChangesIdless function call history
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to Idless Gemini tool calls are now preserved, but parallel idless calls can be incorrectly treated as fully answered when one response is missing. This can retain incomplete history and cause incorrect tool behavior, so pairing must be made count-aware or parallel idless calls rejected before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@includes/Core/AbilityFunctionResolver.php`:
- Line 67: Update AbilityFunctionResolver::execute_ability() and
ConversationTrimmer::validate_tool_pairs() so multiple idless tool calls cannot
be incorrectly matched by a single response; either reject parallel idless calls
or implement occurrence-count-aware pairing. Add a regression test covering two
idless calls with one response and ensure the incomplete cycle is not retained.

Summary
unknown.ConversationTrimmerpath.Why
Gemini 2.5 can return function calls without IDs. The resolver previously assigned the response ID
unknown, while the original call normalized to an empty ID.ConversationTrimmer::validate_tool_pairs()treated that completed cycle as mismatched and removed both messages before the next provider request, causing the model to repeat the same tool call until the loop limit.The companion Google provider change in WordPress/ai-provider-for-google#45 preserves real Gemini 3 IDs and omits this empty compatibility sentinel from older-model request payloads.
