The CLI now uses only the curated public surface. Additions to the public Agent facade: - init/deinit (heap-pin the inner; the handle is a copyable value). - addSystemMessage (.append) and setSystemPrompt (.replace). - compact(override_system_prompt, extra) falling back to the config prompt. - sessionId() accessor. CompactionConfig gains compaction_prompt, which owns the compaction system prompt for both auto-compaction and the explicit compact() default; the Agent.compaction_system_prompt field is deleted. ConversationData is the public name for the owned conversation value type (Session.load returns it, Agent.init adopts it), distinct from the borrowed Conversation handle. Agent.addSystemMessage/setSystemPrompt are kept on Agent (they persist with the SystemMode) rather than dropped as the plan first proposed. 2026-06-05T17:43:43Z t t@tjp.lol 2026-06-05T17:43:29Z urn:sha1:ccdaef8e682960ecadf73d3b2df70559a0baaf56 The Agent now owns its Conversation and a SessionStore, and persists everything it generates as turns progress. Embedders get persistence for free; the CLI no longer drives the session log. libpanto: - Agent.init takes a SessionStore + optional Conversation to adopt (resume path). Agent owns/tears down the conversation; turn-driving methods drop the *Conversation param and operate on self.conversation. - New Agent methods: submitUserMessage (adds+persists the user prompt immediately), addSystemMessage(text, mode), runStep persists the turn on every exit path (incl. partial turns on error), compactAndPersist for the explicit /compact path. Auto-compaction persists its window via runStep's tail. - turn_persist.zig: DiskMessage mapping moved out of the CLI; reads usage off Message.usage (no per-message-usage list). System mode rides on DiskMessage.mode, derived from the System block. - NullStore is now an allocator-bearing struct (frees consumed messages per the store-consumes-messages contract). - Tests: in-memory CapturingStore round-trip + NullStore turn test. panto CLI: - Delete src/session_persist.zig. REPL is submitUserMessage + runStep. - Reorder construction: store -> registry -> agent -> bootstrap -> seed/ reconcile system prompt through the agent -> load extensions. - command.Context drops conv/session_mgr; commands reach ctx.agent. - system_prompt seed/reconcile call agent.addSystemMessage. - CLIReceiver is display-only (per_message_usage removed). Phases 3-5 of docs/pluggable-session-store.md. Behavior preserved; full build + test suite green. 2026-06-02T22:37:32Z t t@tjp.lol 2026-06-02T21:00:44Z urn:sha1:8b88b886346460b1ab29edb03ad85bc3bb565a45
