+**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.
