Borrowed from Claude Code --allow-dangerously-skip-permissions: an escape hatch that skips every permission check should be NAMED dangerous, not sit silently under full_access. Adds ExecutionAccessPreset.DANGEROUS_SKIP with the same strength profile as FULL_ACCESS, so operators and audit logs can tell a deliberate "I know this is dangerous" choice apart from ordinary full access.

Lineage

Part of the 2026-08-19 "Claude Code lessons" branch. The sibling change (instruction-file glob excludes via DEEPCODE_INSTRUCTION_EXCLUDES) already landed on main in reworked form (core/harness/memory.py owns it, with tests), so this PR carries only the still-missing preset.

Verification

tests/domain/test_execution_security.py + tests/application/test_execution_security_policy.py + tests/contract/test_protocol_schema.py + tests/application/test_session_alignment.py + tests/application/test_turn_service.py = 71 passed.

Checks

• Dedup: main has no "dangerous" preset (grep empty).
• Dependency closure: none — StrEnum already imported.
• Scope: additive enum member + one _PRESET_PROFILES entry; no default behavior change (no existing client passes the new value; the protocol-schema contract test passes unchanged).

Thank you, @raymondginger2018-sudo. We're closing this one: as written, the new preset can't be saved, and it isn't the same as Full Access.

• thread/permission/update accepts dangerous_skip, but the risk-acknowledgement check (app_server/dispatcher.py:1198) only applies to full_access, so the new preset skips the confirmation Full Access requires.
• The write then fails: the threads.access_preset_override column only allows ask, read_only and full_access (core/persistence/migrations.py:1227), so the request ends in an IntegrityError (-32603).
• Several places check is ExecutionAccessPreset.FULL_ACCESS (core/harness/policy.py:204-210, core/harness/tools/__init__.py:108-112), so dangerous_skip would keep the sensitive-path denylist and origin approval on: not the same strength as Full Access.
• It is also missing from core/config.py:406, the protocol schema, Desktop and the TUI, and has no tests.

Full Access already asks every client for an explicit risk acknowledgement. If you think its name or warning should be clearer, please open an issue about the wording first; a rename would need a migration, the protocol schema, all three clients and tests in one change. Please also keep code comments in English.
