The write path, and the step where a preference stops being a relabelled rule. `create_preference` / `update_preference` on the MCP surface, plus `kind` on update_rule and both HTTP doors. SEPARATE TOOLS, NOT A `kind=` ARGUMENT. create_rule's docstring IS the approval gate (#3557): propose, offer three answers, wait. That is right for a rule — the person it binds should have agreed. A preference inverts it, and one reached through create_rule would be read through that prose, so the caller would hesitate over exactly the act this kind exists to make routine. Two doors, two contracts, one table. Reads stay shared: a preference IS a rule row, and "what governs this" wants both. Two required fields, each buying something: - `when_to_apply`, because the trigger is two-thirds of the embedded document. Without one the record is written, stored, and silently never delivered — indistinguishable from one nobody wrote. - `arose_from_id`, the price of the ungated write. A corpus that drifts with no record of what taught each change cannot be audited, and the operator's veto over drift is worth exactly as much as their ability to read why it happened. The near-duplicate gate is what lets this corpus be written freely and stay small: the second preference about a thing updates the first. It is title-scoped and kind-blind, so it also catches a preference restating a rule that already binds. The asymmetry is guarded as two PRESENCE facts — the rule door still asks, the preference door still says write it — never as an absence. An absence check passes against a docstring that was deleted or rewritten into something else, which is snippet #3352's warning and would read as coverage here while proving nothing. `_plain_detail` moved to tests/helpers on its second copy, per that module's own reason for existing (#2825).
