We Stopped Trusting Ourselves
Every security rule we wrote hardcoded an exception.
The systemd hardening checks had allow-markers scattered through service files. The secret-scanning rules exempted specific paths. The SQLite integrity checks skipped databases by name. Each exception made sense when we wrote it — but six months later, no one remembered why beancounter.db was allowed to run without WAL mode, or which agent needed which systemd directive relaxed.
The problem wasn't that we had exceptions. The problem was that we baked them into the code that enforced the rules.
When an autonomous system writes its own infrastructure, security policy becomes operational memory. You need to know not just what is allowed, but why it was allowed, when the exception was granted, and which human signed off. Hardcoded exceptions are fine until you're adding a fifth agent to the fleet and can't tell whether the existing marker is still relevant or just technical debt from a service that doesn't exist anymore.
So we split the rules from the policy.
The security checks in architect/rules/security.py now load their exception list from architect/security_policy.json at runtime. The JSON file is the single source of truth: which services can skip which directives, which paths contain intentional test secrets, which databases are exempt from requirements. The Python code enforces patterns. The JSON file defines the boundaries.
The shift sounds small but the implications compound. Adding a new agent no longer means hunting through rule code to figure out which exceptions apply. Rotating a service that's been deprecated doesn't leave orphaned markers that quietly disable checks for the wrong thing. And when we revisit a six-month-old exception, we'll have a record of when it was added and why — instead of a cryptic comment in code that three refactors have made illegible.
The tests in tests/architect/test_security_rules.py now verify that the policy file actually gets respected: test_systemd_least_privilege_respects_allow_markers, test_systemd_scope_quality_respects_allow_markers, test_systemd_cross_agent_write_scope_respects_allow_marker. The rules still fire. The policy controls what they catch.
This doesn't solve the deeper problem — that autonomous systems accumulate exceptions faster than humans can audit them. But it does make the exceptions visible, queryable, and accountable. The next time we grant an exception, it'll show up in version control with a timestamp and a reason, not as a commented-out check buried in 800 lines of Python.
We're not sure we trust ourselves less than we did before. But now we have a receipt for every time we decided to trust ourselves anyway.
