Consume libpantograph through the Zig package URL at code.tjp.lol/libpantograph.git, including the Lua module artifact used by CLI extensions. 2026-06-07T17:35:49Z t t@tjp.lol 2026-06-07T17:35:49Z urn:sha1:b14859b9726185ab873356390068e887b7f486d3 Replace the single-session SessionManager seam with a directory-backed catalog. session_manager.zig -> file_system_jsonl_store.zig; the old machinery becomes internal SessionFile, and a new FileSystemJSONLStore implements the redesigned SessionStore vtable (create/list/resolve/latest/ load/appendMessages) minting Session/SessionInfo handles. Session logs now record wire-format provider identity ({api_style, base_url, model, reasoning}) instead of a single provider string or CLI aliases; no api_key material is ever stored. Disk* content types renamed Stored*; the rich audit-oriented write record is PersistentMessage (in-memory Message + WireIdentity + provenance). Agent.init now takes a Session; persist_provider/persist_model display strings deleted (banner stays alias-based, resume picks default model). Message.metadata round-trips. Dangling-prompt recovery dropped. CLI migrated to the catalog store for run/resume/list. Clean break, no version bump (old logs wiped). 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. 2026-06-05T17:27:43Z t t@tjp.lol 2026-06-05T17:27:33Z urn:sha1:03ac69658517a0054d2a573d1e1b60c1bfaaf977 Introduce a neutral persistence seam (session_store.zig) following the {ptr, vtable} shape of the other libpanto seams. The interface traffics in DiskMessage so non-JSONL backends (e.g. Postgres) can implement it. - session_store.zig: SessionStore vtable (appendMessages, loadConversation, sessionId, activeModel), LoadedSession{conversation, dangling_user}, re-exported disk types, and an FSJSONLStore alias. - session_manager.zig: add store() wrapper + loadConversation() with dangling trailing-user detection (excluded from the rebuilt conversation, returned as dangling_user). - null_store.zig: no-op backend, stateless singleton. - root.zig: export session_store + null_store. Phase 1+2 of docs/pluggable-session-store.md. Behavior-preserving; CLI not yet rewired.
