 * ONE presence rule for a RETIRED key on a caller-supplied bag (a deps object, an options object): the key is
 * PRESENT iff ordinary property lookup answers a defined value — prototype and non-enumerable members included,
 * exactly what the former direct read of the seat honored; an explicit `undefined` reads as absence, as every
 * optional seat reads. Every retired-key door reads through here so no door grows its own idea of "present";
 * each composes its own refusal from the answer. A table row is `{ key: replacement }` — the sentence that says
 * what replaced the seat, quoted in the refusal. A dotted key names a member of a member bag (`attachments.x`),
 * read the same way one step at a time; a step that is not an object or a function holds nothing. A step spelled
 * `name[]` names an array member and reads every element it holds (`skills[].manifest`: any element carrying it).
