+Build a separate binary and exercise the recorder on a private display:
+
+```sh
+go build -o /tmp/cthulhu-interruption-test ./cmd/cthulhu
+CTHULHU_BINARY=/tmp/cthulhu-interruption-test CTHULHU_PREFS_INTERRUPTION_ONLY=1 /usr/bin/python3 tests/native_preferences.py
+CTHULHU_BINARY=/tmp/cthulhu-interruption-test CTHULHU_PREFS_INTERRUPTION_RUNTIME_ONLY=1 /usr/bin/python3 tests/native_preferences.py
+```
+
+This checks all three choices, Tab and Shift+Tab around the new controls,
+recording Tab/Enter/Space/Escape and separate modifiers, duplicate suppression,
+Control+Enter finish, Control+Escape cancellation, replacement, empty-recording
+rejection, Apply and reloading the accepted draft. Direct XTest modifier input
+avoids extra Control presses synthesized by xdotool. Config tests separately
+check disk persistence and application profiles. Application tests apply the
+preference to the live settings and check that unselected keys preserve both
+queued speech and Say All, while selected keys and reader commands cancel them.
+The runtime check starts a private reader and fake speech server. It verifies
+that the read-only summary's contents are spoken on focus and characters are
+spoken while moving with Left and Right. The generic native text-label test
+also covers read-only entries and keeps password contents excluded.
+
+After reviewing the diff and authorizing a reader replacement, verify audibly:
+
+1. Select All keys interrupt and Apply. During long speech, press a letter,
+   Tab, an arrow, Shift and Control separately; each should stop old speech.
+2. Select Control, Enter, Space, and Escape and Apply. Letters, arrows, Tab and
+   Shift should let speech continue. Both Control keys, both Enter keys, Space
+   and Escape should stop it. Repeat during Say All.
+3. Select Define interruption keys. Record Tab, Enter, Escape and Right Control,
+   finishing with Control+Enter. Confirm Left Control was not added. Check the
+   result field, Apply, close, reopen and confirm the list persists. Test each
+   chosen key during long speech and confirm unchosen keys let it continue.
+4. Record a different list and cancel with Control+Escape; the previous list
+   should remain. Cancel the whole Preferences window and confirm unapplied
+   changes do not alter runtime behavior.
+5. Tab and Shift+Tab through the interruption group, recorder button, defined
+   keys and speech history. Check spoken instructions and Braille in recording,
+   normal typing/key echo, browser navigation, reader commands, automatic title
+   repeats, and selected/unselected held keys after applying each mode.
+
+The private checks do not establish live speech, physical keyboard, physical
+Braille or Wayland compositor acceptance.
