"""Session persistence must not strip a custom provider's identity.
``_runtime_model_config`` persists the live agent's RESOLVED provider into
the session row's ``model_config`` JSON. For any named ``providers:`` /
``custom_providers:`` entry (e.g. one called "mimo-v2.5-pro"),
``agent.provider`` is the literal string "custom", so the entry name was
lost — and the api_key is deliberately never persisted. On ``session.resume``
or ``_reset_session_agent``, ``_stored_session_runtime_overrides`` fed
provider="custom" back into ``_make_agent`` →
``resolve_runtime_provider(requested="custom")``, which cannot match an entry
named "mimo-v2.5-pro". Depending on config the rebuild either raised
"No LLM provider configured. Run `hermes model`..." (resume failed) or
silently resolved placeholder credentials ("no-key-required") against the
patched-back base_url.
Fix: persist the REQUESTED/entry identity — ``_runtime_model_config`` maps
the agent's base_url back to the canonical ``custom:<name>`` menu key via
``find_custom_provider_identity``; ``_make_agent`` performs the same
recovery for rows persisted before the fix (and falls back to handing the
stored base_url to the direct-alias branch when no entry matches).
Related investigation: GH #44070 / PR #44099 (credential-pool base_url
pinning); same family of resolved-vs-requested identity loss.
