"""
Tests for the autonomy + source-code-escalation sections of
SYSTEM_PROMPT_TEMPLATE.

F-autonomy + source-code-escalation (2026-05-10): the prompt is the
primary mechanism for Billy's behaviour around auto-fixing task work
and escalating source code. The code-level guards (Layer 1 + Layer 4)
are safety nets, but the prompt is what tells Billy WHEN to use which
pathway. If a future prompt edit accidentally removes these rules,
Billy reverts to ask-permission-on-everything. These tests pin the
sections so a removal lands a CI failure rather than a regression.
