## Security Review — Round 3

VERDICT: approve

FINDINGS:
- [src/colonyos/config.py:701]: Custom CEO profiles parsed via `_parse_personas()` which skips `sanitize_display_text`. The dedicated `parse_custom_ceo_profiles()` in `ceo_profiles.py` sanitizes correctly but is never called from the config loader. User-defined profiles flow unsanitized into the CEO system prompt. **Medium severity** — 1-line fix: swap `_parse_personas` for `parse_custom_ceo_profiles` in `load_config()`.
- [src/colonyos/config.py:702]: `max_log_files` not bounds-checked — negative or zero value from config would cause immediate deletion of all log files. **Low severity** — add `max(1, ...)`.

SYNTHESIS:
The implementation has addressed all critical and high-severity findings from Round 2. Budget/time caps are now enforced at three checkpoints in `_run_auto_in_tui`. TranscriptLogWriter is instantiated and wired into every queue consumer branch. Log files use `0o600` permissions with SECRET_PATTERNS redaction. `.colonyos/logs/` is gitignored. The `auto_approve` guard is preserved. Two-tier Ctrl+C cancellation works correctly without killing the TUI on first press. The one remaining gap — custom CEO profiles bypassing sanitization in the config loading path — is a medium-severity supply-chain concern (malicious config.yaml could inject prompt content), but it's a 1-line fix and doesn't block merge given that the config file is typically under repo-owner control. Conditional approve: fix the sanitization wiring before this ships to users who accept external PRs.
