2. Continuing work locally

[NODE: NON_DESTRUCTIVE_PERSISTENCE]

EVIDENCE: introduction/core/safety_and_nonnegotiables.md, README.md

[NODE: PORTABLE_EXECUTION]

3. Prioritizing a quiet working environment

[NODE: SILENT_OPERATION]
POLICY: The application does not actively play audio or notification sounds.
UNRESOLVED_ISSUE: A known Windows interaction path can produce the general warning sound.
