Every gate on create_rule and create_project_rule was about SHAPE — rule vs
process vs snippet, one-thing-you-could-violate, general-enough, not-a-dupe.
All of them improve a rule someone has already decided to write. None asked
the prior question: has the person this will bind agreed to be bound by it?
Both docstrings now open with the gate, and with the four things a proposal
carries: what it would require in the words it would carry, its intent, why
now, and how it would be enforced.
The fourth is the one that decides it. "A test, a CI check, a hook, a schema
constraint... or nothing" is a question that sometimes dissolves the rule:
what a test can assert should BE that test, and a rule is what is left when
nothing mechanical can hold the thing. A rulebook grows by default and
shrinks only on purpose.
create_project_rule needs the gate more, not less, and says so: a project
rule is absent from an unfiltered list_rules(), and a conditional one is
absent from session start too, so one written there can bind for months
without ever having been in front of the person it binds.
test_rule_creation_asks_first pins structure, never wording — each element
matches a family of synonyms, and the gate must precede the Args: block,
because a caller who has decided to make the call reads the parameters and
not the prose under them.
