## Why Extension tools that need conversation context should be able to read it from the live tool invocation instead of reaching into thread persistence themselves. ## What changed - Add a `ConversationHistory` snapshot to extension `ToolCall`s and populate it from the current raw in-memory response history. - Expose all history items at this boundary so each extension can filter and bound the subset it needs before consuming or forwarding it. - Cover the adapter and registry dispatch paths and update existing extension tests that construct `ToolCall` literals. ## Test plan - `cargo test -p codex-tools` - `cargo test -p codex-extension-api` - `cargo test -p codex-goal-extension` - `cargo test -p codex-memories-extension` - `cargo test -p codex-core passes_turn_fields_to_extension_call` - `cargo test -p codex-core extension_tool_executors_are_model_visible_and_dispatchable`
