+"""Fold an agent-as-provider's own activity back into Hermes' turn state.
+
+Most providers are models: they ask Hermes to run a tool and Hermes runs it, so
+the transcript and the loop's counters see every tool iteration. Some providers
+are *agents* — an ACP CLI reached through a client shim, or the codex
+app-server, which takes an analogous path in ``agent/codex_runtime.py``. They
+execute their own read/edit/execute tools inside their own session, and by the
+time Hermes sees the response that work is already done.
+
+Those calls must never come back as pending ``tool_calls`` — Hermes would re-run
+finished work. But two subsystems go blind if they are merely summarised into
+the ``reasoning`` field:
+
+* the **self-improvement loop**, which distils memories and skills by replaying
+  ``messages`` — a one-line activity feed teaches it nothing;
+* the **skill-review nudge**, whose counter (``_iters_since_skill``) only moves
+  on Hermes tool iterations, of which there are none.
+
+So the provider client hands both back on the completion object and this helper
+applies them: ``hermes_projected_messages`` (already-completed
+``assistant(tool_calls=[…])`` + ``tool(result)`` history rows) and
+``hermes_provider_tool_iterations`` (how many tool iterations happened inside
+the provider). Clients that set neither are unaffected, which is every ordinary
+OpenAI-compatible provider.
+
+The splice is append-only and rows go through ``append_message`` like every
+other live-transcript append, so they carry a timestamp and persist the same way
+the codex projection path's rows do.
