//! What an open question holds: the one decider, read by the heartbeat's gate
//! and by `huginn blocked`, so the two cannot disagree.
//!
//! A question raised in a run holds every claim of that run, the set that
//! failed together; a question raised in anything else holds that item. A
//! question answered with the option `retire` keeps holding the claims of the
//! run it was raised in for as long as they are in force: the answer has said
//! they are not to be worked, and whoever resolves them is the one writer of
//! that. Answering or withdrawing a question with any other choice lifts its
//! hold. The question's text is display only.
//!
//! Nothing here keeps state. Every answer is read through `ask`, one typed
//! selection at a time, so a caller with a daemon and a caller with a
//! temporary mind read the same way.

//! A pool of embedder endpoints serving one model, as one `Embedder`.
//!
//! The endpoints are two tiers. The primaries (the GPU hosts) all take work at
//! once: a batch is cut into contiguous pieces, one per healthy primary, and
//! the pieces are embedded concurrently and joined back in order. The reserve
//! (the CPU host) takes work only while no primary is healthy. An endpoint is
//! admitted only after its model identity (name, digest, dimensions) equals the
//! pool's; one that is unreachable, failing or serving another model drops out,
//! is named in the log, is never written with, and is read again once
//! `retry_after` has passed. A piece that fails on one endpoint is embedded
//! again on another, so a batch fails only when no endpoint is left to take it.
//!
//! The model of the pool is the one the collection was built with: the caller
//! hands it over with `built_under` before it reads the identity, and an
//! endpoint serving anything else never takes work, even when it is the only
//! one up, so a run cannot rebuild an index around a foreign model. Only when
//! there is no collection yet does the pool adopt a model: the first one
//! reported in list order, primaries first, once every endpoint has answered.
//!
//! An endpoint's identity is read off the batch's clock. Each read runs on its
//! own thread under `IDENTITY_WITHIN`, and a batch waits for the reads only
//! while no healthy primary exists to start on: a primary being read keeps the
//! reserve waiting, so a returning GPU is used and not passed over for the CPU,
//! but an endpoint that drops packets never delays work a healthy one can do.

//! It is dropped before the repo's first delete, so a run that fails between

`mind-heartbeat` is the one process that decides who wakes and when: each beat falls when the Minds' voted tempo has passed and goes to the Mind that has waited longest, bent by the urgency she declares and a member addressing her; the operator tagging or naming a Persona launches her at once. `mind-heartbeat timeline` prints its latest record.

# lease_v2 fixtures
The exact bytes of the claude lease protocol v2: each file is one whole frame (a u32
big-endian length, then the named-MessagePack map `{kind, value}`).
- `request.bin`: `claude_lease_request`.
- `refusal_unknown_caller.bin`, `refusal_expired.bin`, `refusal_busy.bin`,
`refusal_provider_rejected.bin`: `claude_lease_refusal`; `kind` is the variant name as a
PascalCase string.
- `grant.bin`: `claude_lease_grant` with `lease_id` and `plan_quota` carrying `five_hour` and
`seven_day` windows (utilization_permille, resets_at_unix_ms, status, observed_at_unix_ms).
On the wire the grant travels with one SCM_RIGHTS fd; the file holds the frame only.
Huginn's lease client vendors these files from this repository and tests against the same
bytes. Generator: `tests/lease_wire_golden.rs`; run it with `LEASE_V2_REGENERATE=1`, then
review the diff: a changed byte is a wire change.

//! What of her own mind enters a Persona turn besides what she is always shown, and in what words.

//! typed memory, and a later turn reads it back from there. Open asks and open

//! chat (the lines shown beside a message are conversation, never memory),
//! keeps no cache between turns, and holds no index: the daemon's index answers
//! `MindPort::query_near`, and a rank only orders.
//!
//! Three lanes, merged in this order and de-duplicated by id, none showing an
//! open item:
//! - `about`: memory in force about any other sender of this batch, ranked by
//! `weight` from the newest `POOL` of them.
//! - `relevant`: memory, follow-up and ruling in force nearest the batch's
//! words, in the daemon's order. A wake has no words and skips it.
//! - `salient`: memory in force ranked by `weight` from the newest `POOL`.
//! On a wake, which has no senders and no words, this is all that runs.
//!
//! Each lane has an item limit and a byte budget, so no one signal crowds out
//! another; a lane that leaves something out says how many.

//! The Self-run actuator's lifecycle decision, and nothing else.

//! `decide(state, event, now) -> (state, action)` is the one owner of when the
//! flush is asked for, when the stdin closes, when a signal goes out and when
//! the run is over (ruling `eureka-body:ruling:self-run-decider`). It performs
//! no I/O and reads no clock: the loop in `carry` turns operating-system facts
//! into events, reads the clock once per event, and executes the action. A
//! timing rule is pinned here, by tables and by an enumeration of event orders.
//!
//! Delivery is counted, not guessed, and at most one write is outstanding (ruling
//! `eureka-body:ruling:self-session-one-outstanding-write`): the CLI joins the
//! lines queued behind a request into one echo, so a second line is never
//! written before the first one's echo. Every stdin line the actuator writes (the
//! start message, a write of tells and the flush) increments `written`; every
//! replay echo increments `consumed`. The echo is the point the CLI takes a line
//! into a request, folded into the running turn or queued for the next. What
//! waits (the briefs, the flush ask) is coalesced into the next single write.
//! Idle is derived: no turn open and no write outstanding.
//!
//! The rules, in this order, while stdin is open and no signal is out:
//! (1) a result that is blocked, or an error before any answer, closes stdin: no
//! cache is worth keeping and a flush would fail the same way; (2) the first
//! result after the flush's echo closes stdin, folded or queued alike; (3) the
//! cap less `ROTATE_MARGIN_S`: ask the flush (rotation), idle or mid-turn; (4)
//! idle with no brief waiting, at the last result's cache lifetime less a margin:
//! ask the flush (idle); (4b) a session told to yield closes stdin at idle, with nothing outstanding and no flush written; (5) with nothing outstanding, write what waits: the
//! briefs and the flush ask if there is one, as one line. The ceiling asks the
//! same flush from a request. Compaction is off in the CLI (`DISABLE_COMPACT=1`),
//! so the flush is the only way a session ends short of its cache.
//!
//! The headroom counts the requests after the flush's echo, from the prefix the
//! flush was asked at. The grace interrupt is at the earlier of the grace
//! after the flush write and the cap less `LADDER_S`, so the signal ladder
//! finishes before the unit's cap (ruling
//! `eureka-body:ruling:flush-always-gets-a-turn`). At most one action comes out
//! of an event; a deadline that is already due yields its action at the next
//! event, and `next_deadline` says it is now.
