 **List.** `list_request`: `{mind, status, cursor, limit}`. `mind` is the route's `{mind}`, a Mind id from the configured list. `status` is `open`, `recorded` or nil for both; `recorded` means a closed card. Cards come **newest first by `order`** (the admission ordinal). `limit` is 0 to 50; **`limit` 0 returns no entries, only the counts and the stamp**, which is what "N open" on the Mind's header needs. `cursor` is nil or `c<N>`: the cards whose `order` is below N; a client treats it as opaque and sends back the `next_cursor` it was given. `list`: `{mind, stamp, open_count, recorded_count, forks[entry], next_cursor}`. The counts cover every card the viewer may see, whatever `status` and `cursor` asked for. `stamp` is `s<N>`, N the receiver's last-seen Huginn admission ordinal for the Mind's desk documents: the same stamp means the same state, so a desk polls `limit` 0 and fetches bodies only when the stamp moves. `next_cursor` is nil on the last page. An `entry` is `{card, record}`: the card and its `record` (the answers with their outcomes and the derived `counted_answer_id`).
 
-**Read.** `read_request` is `{mind, fork_id}`; the response is the `entry` for one fork of that Mind. Its `card.options_hash` is **computed by the server** from the five shown members as in "Options hash" and the client recomputes it from what it rendered; a card whose hash is not the hash of its members is no card (negative vector `card_hash_wrong`). The record's `fork_id` and `options_hash` are the card's, and `counted_answer_id` is derived, not copied (negative vectors for each). Which cards and answers a viewer may see follows the card's audience (PR #24 section 5); a fork the viewer may not see is `fork_unknown`, not a different refusal.

The read and list shapes are unchanged and carry no audience field (`eureka-substrate:question:desk-read-visibility`, Heimdall's option (c)).
 
 **Answer.** The body is the `answer_request` and nothing else a client may set: `fork_id`, `options_hash`, `answer`, `answered_at`, `request_id` (plus `retracted` and `retracts`, written `false` and nil unless the call retracts). The response is the stored outcome: `Counted`, `Revision`, `Retraction`, or `Refused` with its code, and the **`counted_answer_id`** the fork has once this call is applied (`n<seq>` or nil; derived as in "The counted answer is derived", the same value the `record` projection carries, so the desk needs no second read). A replay returns the stored outcome with the `counted_answer_id` current at the retry, not the one it had when first stored. **A `stale_fork` refusal carries the current card** in `answer_result.card`, so the desk can show the new fork without another read. Nothing is stored for a step 1 or 2 refusal, an unknown fork (or an unknown Mind, or a fork another Mind holds) or a `request_id_conflict`. `unavailable` promises nothing either way.
