-- **No more ghost/duplicate input prompt while the agent works.** The input card no longer fossilizes above the stream as a second, ghostly prompt; the prompt bar and top border stay visible through turn-start and lazy-load frames; running-agent output renders through a stable diff-rendered scene (ported from Pi); and an experimental Focus TUI mode (`tui.focus_mode`) pins the composer and hides file activity behind a compact live shelf.
-- **Added a native `/benchmark` command suite.** Run deterministic local Pythinker model evaluations with bundled smoke tasks and SWE-style JSONL tasks (`/benchmark:swe`), plus `/benchmark compare`, `/benchmark export`, and `/benchmark discover` actions with replayable artifacts and branded markdown reports.
-- **Hardened benchmark and skill security edges.** SWE verification commands are shape-validated before execution, benchmark discovery requires explicit network opt-in, and active-skill deactivation failures now surface instead of being swallowed.
+- **Agent core deepened with an observable request-assembly path.** Provider handoff, prompt ordering, and context persistence now run through explicit compatibility contracts, conversation history updates are transactional (atomic replacement with cancellation and rollback), and agent/skill definitions resolve through one source-aware catalogue instead of scattered lookups.
+- **Agent-spec loading is more defensive and truthful.** Subagent `path`, `extend`, and `system_prompt_path` references that resolve outside their spec's directory are now rejected instead of loaded, and malformed frontmatter parsing errors are no longer misreported as harmless skips.
+- **Thinking and subagent activity render cleanly in the terminal.** Live reasoning previews render complete Markdown without exposing stray HTML comments, and activity-tree rows stay visually stable during long-running turns.
