**Total: 38 new tests (250 total in suite)**
## Bugs discovered
None.
## Observations for future iterations
1. **Input::from_files is async and I/O-heavy**: It fetches URLs,
reads files from disk, expands globs, and runs external commands.
Full testing requires integration tests with temp files/dirs.
2. **resolve_role with agent**: Testing requires an initialized
Agent (which needs config files on disk). The agent path is
tested indirectly through the existing `exit_agent` test in
iteration 4.
3. **resolve_paths is a pure function**: No I/O, fully testable.
It cleanly separates path classification (URL vs local vs cmd
vs loader) from actual loading. Good design for testing.
4. **select_functions has complex filtering**: It filters non-MCP
declarations by enabled_tools, then adds user__ functions for
non-agent contexts, then merges agent-specific functions. The
MCP selection mirrors this with MCP-prefixed declarations.
Both paths fully tested.
5. **Input captures state at construction time**: All fields
(stream_enabled, session, rag, functions) are captured from
RequestContext at Input creation. This snapshot-at-creation
pattern means the Input is independent of later context changes.
6. **The %% syntax for last-reply carry-over** is detected in
resolve_paths (pure function) but the actual last_reply
retrieval happens in from_files (async). Tested the detection
part.
