Tools added or removed mid-conversation can be surfaced to the model, but the beta capability is gated off by default.
New logic lets the assistant see tools added or removed mid-conversation via a fresh system turn re-normalized with surfaceLateToolAdditions, instead of only picking up tool changes at the start of a turn. Message normalization gains a toolChangeFallback path and a blocksEligible flag, but the behavior only activates when the beta capability mid_conv_tool_change is included in the request, which itself requires a Statsig-style gate to pass plus per-model eligibility, so it's gated off by default.
