2026-06-05Add pluggable SessionStore interface with FSJSONL + Null backendst
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.

2026-06-01Rename system extension layer to base for clarityt
Replace all references to the "system" layer with "base" to better reflect its role as the foundational extension/tool layer in panto's hierarchy. The layer hierarchy now consistently uses: project > user > base. Includes: - Update agent README and build.zig documentation - Refactor tool registry and config module to support layered lookups - Add TestHarness abstraction for cleaner test setup - Improve JSON serialization with wire-encoded tool names - Add glob pattern matching for tool/extension discovery

2026-05-27Finish the hard parts of the lua makeoverT
- bundle luarocks source in the panto binary - bootstrap process (intended for first `panto` run): - make ~/.local/share/panto/... - write out luarocks sources into it - run luarocks to install luv - new `panto bootstrap` command just runs the bootstrap - `panto bootstrap --force` removes everything and re-bootstraps - new `panto lua` command just runs panto's embedded lua

2026-05-27separate event for providing tool detailsT
OpenAI and Anthropic have tool details (id, name) converge on different timelines. In all cases they are available in `onBlockComplete` which comes with the full block, and previously we had an optional `BlockMeta` argument to `onBlockStart` - the anthropic timeline. We removed the `BlockMeta` from `onBlockStart` since it was always going to be unreliable, and now have an explicit `onToolDetails` instead. This allows us to provide the tool id and name as early as possible from the openai provider (could be in the middle of content deltas), and provide a reliable signal across providers. Also, fix test output.
2026-05-27Stream OpenAI tool_use as discrete blocks; drop BlockMetaT
Close each tool_use on next-index delta (and at finalize) so receivers see one start/delta/complete trio per tool, matching Anthropic. Log+drop fragments for already-closed indices. Remove BlockMeta from the Receiver interface: tool id/name can't be reliably known at onBlockStart under OpenAI's streaming model. Receivers get identity from the assembled ContentBlock at onBlockComplete. CLI renders 'tool: {args} : (name)' accordingly.
2026-05-27finish lua runtime makeoverT
- new multi-tool registration via ToolSource - thread per source-or-standalone-tool - switched to zig 0.16 Io threading interface - cli: include `luv` package and run concurrent lua tools via libuv - one single long-lived lua_State for the whole cli program
