Module session_lifecycle 

Model resolution + connect-event + initialize-result mapping. Mirrors the relevant portions of upstream’s agent-sdk/src/bridge/session_lifecycle.ts.

What lives here:

• normalize_model_key + humanize_model_id
• model_keys_are_compatible / same_context_suffix / same_family_and_version / has_variant_sibling_conflict
• resolve_catalog_model / resolve_current_model
• current_model_is_authoritative
• current_models_equal / refresh_current_model
• map_available_models (initialize-response models array → typed)

What does NOT live here (despite upstream parking it in session_lifecycle.ts): mode list logic (see commands.rs), MCP reconciliation (see mcp.rs), AskUserQuestion sequencing (see user_interaction.rs), the bulk of permission/elicitation routing.

map_available_models

Mirrors mapAvailableModels(models) - initialize-response models array → typed AvailableModel. Drops entries lacking a non-empty value or displayName.

model_keys_are_compatible 🔒

normalize_model_key 🔒

resolve_catalog_model 🔒

resolve_current_model_from_inputs

Mirrors upstream’s resolveCurrentModel. Pure function on the session’s resolved/runtime/requested model strings + the available_models catalogue. Primitive-arg form - callers pass what they have; no session struct dependency.

same_context_suffix 🔒

same_family_and_version 🔒
