+- **Migration Prompt Safe Default on Failure** (#7503): Fixed
+  `MigrationRunner._default_prompt_for_migration` silently auto-approving destructive
+  database migrations when the interactive prompt raised any exception. The handler now
+  catches only `(IOError, OSError, EOFError)` (broken stdin / non-interactive pipe),
+  logs a `WARNING` instead of a `DEBUG` message, and returns `False` (reject) so that
+  migrations are never applied without explicit user consent. `KeyboardInterrupt` is
+  re-raised so Ctrl-C always works. Non-interactive environments (stdin not a TTY) also
+  now return `False` by default; use `CLEVERAGENTS_AUTO_APPLY_MIGRATIONS=true` or the
+  `--yes` CLI flag to approve automatically.

 - **Validation Gate Empty-Run Guard** (#7508): Fixed `ApplyValidationSummary.all_required_passed`
   returning `True` when zero validations were run, silently bypassing the apply gate. The property
   now returns `False` when the validation result set is empty (`is_empty` is `True`), ensuring

+Feature: TDD Issue #7503 — migration_runner _default_prompt_for_migration must reject on exception
+  As a database administrator
+  I want the migration runner to refuse migrations when the interactive prompt fails
+  So that destructive schema migrations are never applied without explicit user consent
+
+  The root cause is that `_default_prompt_for_migration` in migration_runner.py
+  catches all exceptions with `except Exception` and returns `True` (auto-approve).
+  This means any prompt failure (broken stdin, IOError, EOFError) silently applies
+  destructive migrations to production databases without user confirmation.
+
+  The fix narrows the exception handler to `(IOError, OSError, EOFError)`, logs at
+  WARNING level, and returns `False` (reject) instead of `True` (auto-approve).
+  `KeyboardInterrupt` is re-raised so Ctrl-C always works.
+
+  Scenario: Prompt failure due to OSError rejects migration
+    Given a migration runner configured for "sqlite:///:memory:"
+    When the default migration prompt raises an IOError while prompting
+    Then the default prompt should reject migration after the IO failure
+
+  Scenario: Prompt failure due to EOFError rejects migration
+    Given a migration runner configured for "sqlite:///:memory:"
+    When the default migration prompt raises an EOFError while prompting
+    Then the default prompt should reject migration after the EOF failure
+
+  Scenario: Prompt failure due to unexpected exception rejects migration
+    Given a migration runner configured for "sqlite:///:memory:"
+    When the default migration prompt raises an unexpected exception while prompting
+    Then the default prompt should reject migration after the unexpected failure
+
+  Scenario: Non-interactive environment rejects migration by default
+    Given a migration runner configured for "sqlite:///:memory:"
+    When I evaluate the default migration prompt in a non-interactive environment
+    Then the default prompt should reject without interaction
+
+  Scenario: KeyboardInterrupt propagates from migration prompt
+    Given a migration runner configured for "sqlite:///:memory:"
+    When the default migration prompt receives a KeyboardInterrupt
+    Then the KeyboardInterrupt should propagate from the migration prompt
+
+  Scenario: Explicit auto-approve env var still approves migration
+    Given a migration runner configured for "sqlite:///:memory:"
+    When I evaluate the default migration prompt with CLEVERAGENTS_AUTO_APPLY_MIGRATIONS set to "true"
