 - **Not hashed:** `fork_id` (bound beside the hash), `leans` (an option id or nil), `flag`, `raised_in`, `deciders`, `status` (`open` or `closed`), `ruling` (the ruling id when a ruling closed the fork; nil when the card is open, and nil on a closed card whose question was withdrawn or otherwise resolved with no ruling), `ruled_from` (answer ids a ruling has been admitted from; non-empty only on a closed card), `order`, and `options_hash` itself.
 - **`deciders` is read-only data.** The list is set outside the Mind, through Bifrost's admin path, and **Bifrost sends it per call**: Huginn keeps no copy (M5). The card projection copies the list the call carried. **The list holds one to 64 ids** (Huginn's bound), on the card and in the per-call list alike (vectors `deciders_at_the_cap_of_64`, `deciders_65`); the per-call list has no schema here, so the bound is stated for the cut that builds it. A question's own `audience` may only narrow it. A Mind never writes it, so a Mind cannot add itself and answer its own fork.
-- Rules a schema cannot say, each with a negative vector: a `depends` line is at most 1000 UTF-8 bytes (the schema bounds 8 lines and 1000 characters; bytes need the rule); option ids are unique; `order` is unique among a Mind's cards (a list or card set with two cards on one `order` is refused, naming both fork ids); `recommendation` and `leans` name an option; deciders are unique; an open card names no `ruling` and its `ruled_from` is empty (a ruling that answers a fork closes it); `ruled_from` is non-empty only when `ruling` is set; a closed card may name no ruling (the question was withdrawn, superseded or deferred: step 6 reads `status`, not the ruling); `options_hash` equals the hash of the shown members.

 8. The stamped `authority` field is an attribution, not an authority (above); renaming it `attribution` would say so, at the price of a new key the door must also refuse in a body.
 9. The claims Bifrost verifies are PR #24's open item 5. (The audience `bifrost-desk`, the three routes and the scope names are ruled by Heimdall.)
 10. The second door's wire between Bifrost and Huginn (pending Eureka's cut spec). `unavailable` is a document of its own, outside the refusal set, so a desk can retry it; calls 1 and 2 use it too when Huginn is down (vectors `huginn_down_*`).
