The next declaration read therefore +contains the new catalog without appending synthetic user-history entries or +rewriting the system instruction. + +The presentation ledger, unlike the catalog, does follow the active model +context. A delivery surface commits a mark only after the carrying `tool_search` +result enters active history, and rolls that commit back if the send fails +before the push. Surfaces that execute a batch sequentially gate the whole batch +against a snapshot taken before it starts, so a `tool_search` earlier in the +same batch cannot self-authorize a sibling `tool_call`. Every history mutation +that can evict a tool result — compression, `/clear`, resume reload, +rewind/truncation, and stripping an orphaned turn that carried a tool result — +clears the ledger, so an affected tool must be searched again before it can be +routed. Revealed (directly declared) tools are unaffected: their schemas stay in +the function-declaration list regardless of history. + +## Execution and safety + +`tool_call` is a transport bridge, not a separate executor.

The provider-facing response keeps the original `tool_call` name and +call ID so request/response pairing remains valid. + +Reaching the catalog no longer depends on reminder text surviving in history, so +nothing is re-injected after compression or resume. Execution still requires +that the target schema was actually presented to the model: the registry keeps a +session-scoped presentation ledger mapping each proxied tool to the schema +fingerprint `tool_search` delivered, and `tool_call` rejects a target whose mark +is missing or whose fingerprint no longer matches the live schema — issue +#6721's fail-closed gate against routing guessed or stale arguments. This does +not grant access to arbitrary tools: only live, hidden, proxy-eligible deferred +tools with a current presented schema may be targeted. + +Subagents and teammates keep their existing direct declaration surface and do +not receive `tool_call`, preserving their tool restrictions.
