Module acp_session_store 

ACP session persistence.

Storage shape:

acp_sessions
  ├── acp_messages (FK by integer id)
  │     └── acp_tool_calls (FK by integer id, two rows per call:
  │                          one event_kind='in', one 'out')
  └── acp_session_events

Token tracking: acp_sessions.token_count holds the most recently provider-reported input_tokens (total prompt size). Replace-on-write after every turn. The TUI ctx bar reads this on resume.

Enums (Rust-side): ToolEventKind is internal to this module — callers invoke append_tool_call_in / append_tool_call_out as distinct methods and never see the enum. Action and EventOutcome from zeroclaw_log are the canonical taxonomies for acp_session_events.

AcpSessionSummary

Lightweight summary for the ACP session picker. Avoids loading the full message history just to render a one-line label per session.
