/policy-algebra

Generates frozen, drift-checkable governance rules from thin intent strings (deep interview) or rich plan inputs (shallow confirmation). Produces fenced Starlark blocks callers can inject into downstream work, and exposes --verify for canonicalized drift detection.

Invocation

/policy-algebra <target>                      # generate rules
/policy-algebra <target> --write <path>       # generate + persist raw block
/policy-algebra --verify <frozen> <candidate> # drift check

<target> is a readable file path (SHALLOW mode) or an intent string (DEEP mode).

Adaptive input detection

if target is a readable file path:
    mode = SHALLOW
