**Total: 70 new tests across iterations 9+10 (342 total in suite)**
## Bugs discovered
None.
## Observations for future iterations
1. **Clap parsing is fully testable**: Using `try_parse_from` with
synthetic arg arrays, all flag parsing and combinations can be
verified without running the actual binary.
2. **Cli::text() has stdin dependency**: When stdin is not a
terminal, it reads from stdin. This branch can't be easily
unit-tested. The terminal-detection branch (no stdin) is tested.
3. **Prelude is async + filesystem**: apply_prelude needs real role
and session files. Deferred to integration tests.
4. **Mode selection is runtime behavior**: The actual mode branching
(REPL vs CMD) happens in main.rs based on parsed flags. Testing
the flag parsing verifies the inputs to that branching logic.
5. **Exclusive flags**: Vault flags (--add-secret, --get-secret,
etc.) are marked `exclusive = true` in clap, meaning they
can't be combined with other args. This is enforced by clap.

**Total: 39 new tests (311 total in suite)**
## Bugs discovered
None.
## Observations for future iterations
1. **AssertState has 4 variants with distinct semantics**:
- True: any of the required flags must be present (OR)
- False: all of the forbidden flags must be absent (AND)
- TrueFalse: True AND False simultaneously
- Equal: exact flag match
This is a critical invariant for REPL command availability.
2. **The .agent command uses AssertState::bare()** (Equal(empty)),
meaning it's only available when NO other scope is active. This
is stricter than False — it requires exactly empty state.
3. **All 39 REPL commands** have correct dot prefixes and non-empty
descriptions. Verified as structural invariants.
4. **The multiline ::: syntax** is handled by a regex that requires
both opening and closing markers. The ReplValidator marks
single-marker input as Incomplete for the line editor.
5. **Command handler tests** (the actual .role, .session, .agent
implementations) require full async RequestContext with
filesystem access. These are integration tests and are deferred.
