From ccdaef8e682960ecadf73d3b2df70559a0baaf56 Mon Sep 17 00:00:00 2001 From: t Date: Fri, 5 Jun 2026 11:43:29 -0600 Subject: Move session persistence into the Agent; collapse CLI plumbing 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. --- libpanto/src/root.zig | 1 + 1 file changed, 1 insertion(+) (limited to 'libpanto/src/root.zig') diff --git a/libpanto/src/root.zig b/libpanto/src/root.zig index 39797dd..a49a428 100644 --- a/libpanto/src/root.zig +++ b/libpanto/src/root.zig @@ -12,6 +12,7 @@ pub const session = @import("session.zig"); pub const session_manager = @import("session_manager.zig"); pub const session_store = @import("session_store.zig"); pub const null_store = @import("null_store.zig"); +pub const turn_persist = @import("turn_persist.zig"); pub const pricing = @import("pricing.zig"); pub const compaction = @import("compaction.zig"); pub const image = @import("image.zig"); -- cgit v1.3
