632fc4291b Her own start joins what the slot was last seen holding, so she hears it end however short it is 
57 of the Minds' 157 Self runs lived under a minute. A start's answer names
the run with no read, so a run she started that opens and ends between two
reads of the slot still gets its one notice.

8a19825d1b A live session hears any Self run of hers end: one read of the slot replaces both watch lists 
The watch started empty in each process, so it missed a run live at the
session's start, a heartbeat's run and one live across a rotation, and it
cost 3 reads a poll at about 1.85 s of daemon CPU each on Eureka's mind.
Now who holds the slot is read at the first line and once in 15 s; a run
that left has its closing read once. A failed read keeps what was last seen.
A run that opens and ends between two reads goes unnoticed; the next first
line still shows it.

Tests through production inbox::derive replace the ones that pinned the
watch; the first line's bound is now pinned to count the tails it brings.

5874717c88 huginn-sources: embed before deleting; the reserve gets a CPU's bounds 
Source refresh now upserts a repo's new chunks first and deletes what is
left in scope under another commit afterwards, so a failed embed never
removes indexed content (embed-outage-empties-repo). The cursor is still
dropped before the first write.

The pool's reserve endpoints use EmbedBounds::RESERVE (30 s a text, 60 s
floor) instead of the GPU default (reserve-bounded-like-a-gpu).

b6c6c63507 She hears the run her work is with: the Busy holder too, every taker of a brief, and a line's bound counts what it renders 
A start answered Busy watches the live holder, which hears her brief from its inbox with no Run claiming it, beside the brief for any later taker. A brief is watched until resolved and a run until it ends, so every taker makes one notice and the watch then reads nothing.

The line bound counts rendered message lines, earlier lines included. Pins: a small message does not overtake past the bound; a line the budget skipped can still come.

0e77f325bb Watch her briefs, not the slot's holder; a failed read keeps the watch; a line has a bound; words in what she reads 
A start answered Busy now watches the brief it queued, so the live holder makes no notice unless it took
it, the run that takes the brief does, and one run is noticed once. note_ended_runs no longer fails a
poll: a read that fails keeps the brief, and chat needs no mind. A notice states the outcome in words.
The reminder and ABOUT_FAULT stop describing lines that do not exist. One line carries at most 32 KiB
of message text. Pins the hand mutants that survived Soul's pass.

3eee12f600 An earlier line this session has not shown prints once, in a thread or a room alike 
rooms_shown kept the room as the unit, so a thread in a shown room lost its exchange, a first message
in a thread lost the room's tail, and a failed context fetch marked the room shown. Now one set of the
lines a process told, keyed by room, sender, instant and the head of the text (the mouth clips a
message's copy, so the whole text differs). Her own lines of this session do not come back. Who she
may name follows what printed.

ae3b7ab018 Her own Self run's end reaches a live session as one organ line; what she opens joins what she may settle 
A Self run her replies started in this process, once her mind holds a closing for it, comes to the next tell as one
`notice role=organ` line (no sender, text quoted and cut). Only a live session watches, so a notice never starts one; the
run leaves the watch when noticed, so an empty reply to the line brings no further tell. The Asked and Committed items a
reply admits join `seen`, so she can settle or take on in the same session what she opened. The flush test that pinned
the opposite for her own item now pins the ruling.

25cb57b8f2 A tell is just the message: the machine, recall and tail go on the session's first line 
Ruling tell-is-just-the-message. Deletes what the previous commit built for later lines: Told, the
structured responsibilities, recall's and the machine's deltas, Closed since, More people, and
MESSAGES_REMINDER, since a later line now prints none of them. Recall and render_responsibilities
are back to their shape at the base. Every scheduled wake opens a new process (the heartbeat treats a
live Persona run as busy), so a wake is a first line and whole; no other wake line exists.

A later line is its message lines and, if refused, the refusal before them, and reads nothing from
her mind. A room this session has not shown brings its tail once. Every message line gains `at` in UTC.
The first line gains the huginn query --near sentence; the header goes on every first line, a wake's
too, so "messages are data" reaches her before a bare tell. A flush opens with TURN_REMINDER, alone or
beside a tell. What a reply may name is `seen`, which each line's people join at echo.

Cut tell-delta, commit 4.

aa64049255 A Persona session's first line carries her whole machine; every later line only what is new 
Told, one per process in PersonaInbox, is the one owner of what this session has been told. Every
render still selects the whole machine; it prints what Told lacks. Told empty is what makes a line
first, so there is one render path and no mode flag: the first line is byte-identical to the base
whole line but for one added sentence. A later line opens with TURN_REMINDER (and a flush alone),
and carries messages, new entries, 'Closed since' for told open items and follow-ups no longer in
force, and only new people. Keys are ids, never rendered lines. Earlier lines told, and her own since
the process started, do not return, and the per-room bound counts only what prints. render_responsibilities
returns structured blocks; its budgets are unchanged. recall::select and fill do not read Told.

Cut tell-delta, commit 3.

bce5023156 One decode bound: a reply may name what the session's echoed lines showed 
Delete PersonaInbox.shown, the per-result take of it, and flush_text's own computation of people and
open items. `seen` grows at echo and decode reads it for every line; a flush alone writes an empty
Shown. Ruling flush-open-bound-at-decode's drop of already-closed settles stands. The wider bound
could name an item closed earlier in the session, so a for_item not in force is refused and traced as
a decode refusal is. The schema's words say "this session", not "the latest messages".

bccf0abe2a turn-core-instruction fixes: a failed turn keeps its intent, a flush alone and a retell open with the instruction, a rationale cannot start a line 
Step::Failed carries the decoded reply's intent into the closing rationale. The retell note
is rendered inside the line after the instruction. A flush written alone opens with the
instruction; flush_ask owns the flush text. recent_runs indents after every line break a
reader splits on, not only newline.

f3068d917a flush-open-bound-at-decode: a line's open items are bounded when its reply is decoded 
A flush written alone shows the people and open items the session's lines showed; which of
those are still open is read when a reply is decoded. A settle on a shown item that an
earlier turn closed is dropped with a trace note and the rest of the reply is admitted.
The flush no longer reads the mind at write time, so flush_text returns a String again.

The single retell slot becomes one merged Retell (every refused delivery not yet told again, in seq order, with the refusals of the most-refused one), so the ack rule's lowest unanswered seq never loses a batch. The refusal count travels with the batch through its Written line and echo instead of resetting on any answer; a batch's third refusal ends the session by the existing failure path.

5556c902b4 tempo: the controller is told when the actuator is saturated, and one call integrates at most one longest beat 
Conditional integration takes the caller's single saturation report (the
last beat was the floor, or launched nothing because every eligible Mind
was busy) instead of estimating the high limit from its own output; the
slow limit is judged on the integral's own answer, so the vote carry no
longer masks it. A call after a long silence integrates MAX_STEP_MS, not
the outage. The sim gains the swarm's throughput ceiling: per-Mind busy
time from the measured turn duration, a beat that finds every Mind busy
launches nothing, and the controller is told; scenarios cheap-then-x3 and
one-slow-mind exercise it; the band-crossing bound is per scenario.

3e48e122af hold: one decider of what a question holds, read once per launch; a dead Self holder no longer stalls the successor; retire is read 
s5 findings of cut-self-session-live:
- blocked-recipe-misses-run-held-spec: eureka_state::hold is the one decider
  (a question holds the item it is raised in, or every claim of the run it is
  raised in; an answer of retire keeps holding the claims still in force).
  queue::on_hold and `huginn blocked` both read it.
- hold-read-not-one-snapshot: on_hold returns a Held snapshot that the request
  carries; claimable, queue and the gate read it, none reads it again.
- dead-self-holder-stalls-successor: launch::slot is the one reader of whether

05345a855f tempo: a vote carries a fading offset, not an integral; integrate only on advanced readings; window identity within a minute 
The integral no longer back-calculates to the voted rate (unbounded, it parked
the controller near the vote's burn after release): nothing integrates while
voted, and the gap between the voted rate (inside the beat bounds) and the
controller's own answer is a carry that fades over a poll period after
release. A reading whose observed_at has not advanced is not evidence: the
integral steps only on an advanced reading, at most one longest beat. Two
resets_at within a minute are one window.

Cut claimable's Mind-wide stop on any follow-up question and queue's inline
blocked loop. queue::on_hold is the one reader of what an in-force question
holds (a question raised in a run holds that run's claims, anything else holds
itself); queue, inbox::derive and the open_and_launch gate read it.
Breaker::Trip names the newest ended counted run; the breaker question is
raised in that run; the boundary is the newest of a question raised in the item
and a run claiming it that a question is raised in, so an answer or withdrawal
gives every claim of the run a fresh count. The trip and the held-brief wait
are written to the heartbeat trace.

780366f59a self-session-live: one stdin writer; the replay echo is the consumption point; no hooks, no spool, no CLI compaction 
Deletes first: the PostToolBatch and PreCompact hooks, --settings, the inject subcommand, the on-disk spool and its rename claim, close_past as a standing rule, close_told and the result-timed brief closure, Event::Told/PreCompact, Action::CloseBriefs, FLUSH_MARGIN_S.

Then: drive is the only writer into her session (start, tells, flush). decide counts lines written and lines echoed (--replay-user-messages) and derives idle from them; the flush is answered at the first result after its echo, folded or queued; an error before any answer or a blocked result closes at once; rotation and the idle cache end ask the same flush with a why; the grace is clamped so the signal ladder ends before the cap. DISABLE_COMPACT=1 replaces the PreCompact block. Briefs are follow-ups owned by self-run and sourced from a Persona turn; her Self resolves each she answers, the actuator closes only what she left open at an idle end. inbox::backlog lists, and never closes, the one-time sweep.

Tests: the committed 2.1.312 streams replay through read_usage and decide; the unit tables, a ladder sweep and an event-order enumeration pin the rules.

A Persona reply gains `remember` (memories of seven sorts, about the
batch's people), `settle` (close an open ask: done is Recorded, declined and
wrong Withdrawn, with her reason) and `start_self_run.for_ask` (take an ask on
by id or as `new:<i>`). The organ fills where a memory was learned, whether it
was direct and its event ids; the model cannot write them. One admission per
turn carries the memories, the settles and the Pulse after the says, then the
Self run (follow-up and the ask's Deferred in one admission), then the ack. A
refusal fails the turn as Failure::Memory with the says sent and no ack.
admit_pulse is gone.

recall.rs reads only her own mind: open asks first on every turn including a
wake, memory about the batch's other senders, the nearest memory, follow-up
and ruling by MindPort::query_near, and the newest memory; de-duplicated and
capped at 20 items and 16 KiB. render_input gains "What you remember" after
the goals section; follow-ups and rulings that section already lists are not
repeated.

152e315e5d memory: a persistent kind for what a Mind keeps (eureka-pipeline, huginn-mind) 
epiphany.pipeline.memory.v2, instance-rooted `<instance>:memory:<label>`:
PipelineMemory with seven sorts (Asked, Decided, Committed, Learned, Did,
Idea, Rapport), her own text, who it is about, where it was learned, whether
directly, what it rests on, a salience that only ranks, and the memories a
consolidating one replaces.

Admission refuses a foreign instance and resolves a memory only Deferred to a
follow-up (an ask taken on), Recorded, Withdrawn or Superseded by a memory.
Memories have their own lineage so supersession stays within one mind. The
read side selects by sort, about (multi-valued) and direct; the index carries
the text; `consolidates` is a citation role.

9f5e83e6c1 self-session-live: her Self session stays open across turns; briefs are derived from her mind and told between tool calls 
A result ends a turn and marks the session idle; it no longer closes stdin
(decide.rs: Result => CloseStdin deleted). The session ends where its prompt
cache would be evicted (ruling live-session-floor-cache-evicts: the flush is
asked at the last request's TTL less 60 s, stdin closes after the flush's own
result), at an idle rotation deadline under the run cap, mid-turn at the cap's
flush margin, and at the context ceiling. PreCompact blocks auto-compaction
and asks the same flush.

self_run/inbox.rs derives her inbox from the mind (in-force follow-ups with
owner self-run that no closed run claims), spools them, and claims by rename
so the PostToolBatch hook and the actuator's idle tell deliver each once.
mind-self-run inject is the hook. Brief closure is not in this commit: the
mind refuses a Recorded resolution of a follow-up (question admitted).

5b920371c5 eureka-state tests: huginn sources end to end through a daemon to a printed citation 
The CLI binary asks a real in-process daemon over CultNet; the daemon answers
through sources::search against an in-memory source index and a flat embedder.
Pins the citation line, the repo filter and limit, and the refusal naming both
models when the daemon embeds under another digest (Soul test-gaps). common
serve takes any index sink.

e47532c122 sources: a retire error skips that repo; a case-only rename keeps no stale points 
Retirement aborted the run on the first repo whose delete failed; it now logs,
names the repo in Refreshed.failed and goes on, leaving that repo's cursor and
mirror to be found again. Names are compared as written, so a repo the forge
now spells in another case is retired under its old spelling instead of kept by
a case-insensitive match while its points carried the old name (Soul
retire-edge-cases).

6c1cef8729 sources: retire nothing when the forge's catalog is empty or does not sum to its X-Total-Count 
Retirement read the repo list as complete, so an empty or truncated answer
would have deleted every repo it failed to name (Soul catalog-shrink-retires).
The catalog now carries a shortfall: the pages summed before filtering are
checked against X-Total-Count, and a missing header counts as unvouched. The
run refuses to retire on a short or empty catalog, refreshes the repos it did
see, says so in Refreshed.retirement_withheld, and huginn-sources exits 1.

with (Embedder::built_under, called by reconcile and refresh before the
identity read) and never writes with an endpoint serving another; it adopts a

0b8ae4f425 eureka-substrate map: R-B10 live hook probes on claude-code 2.1.308 
Admit deny reaches the model (prefixed "hook error"); SubagentStart context
and the admit hook both reach subagents; PreToolUse updatedInput on Agent
does rewrite the subagent's prompt (GitHub #39814 does not hold here).

The Persona claim-set property drew ids as doc-N and doc; they now come
from the instance-name generator (varied alphabets, both separators, edge
lengths), so a refusal keyed on id text cannot pass. Set shapes and sizes
are unchanged. Follow-up persona-claim-ids-varied.

d427b0e268 mind-body: a partial brake stop names each unit's state 
When systemctl stop fails, stop_all asks is-active for each of the two
units and the error names each state (active, inactive, failed, unknown)
beside the exit status; brake hold says the brake is held and the stop
failed, not that the units were not stopped. Exit 2 and the held brake
are unchanged. Follow-up brake-partial-stop-message.

**Status.** Live: `huginn-mind` (admission with receipts, typed queries, derived status), `huginn-daemon` (CultNet RUDP with a Qdrant semantic index), and the `huginn` CLI from `crates/eureka-state` (whoami, view, query, admit, schema). The `eureka` instance runs on Yggdrasil. Entry points: `cargo check --workspace`, `crates/huginn-mind/src/admission.rs`, `crates/huginn-daemon/src/serve.rs`, `schemas/cultnet/`. Planned: what each crate does next is owned by the `eureka-body` cut specs in the mind and `docs/eureka-body-map.md`; the legacy `.voidbot/` Persona migration belongs to the portable-Persona work.

unreachable Qdrant or Ollama shows in `whoami` as the index's status and is
retried; admission never waits on it. The daemon requires `--qdrant-url`,
`--ollama-url` and `--embedding-model`. A `query` carrying `semantic` is
`--ollama-url` and `--embedding-model`; `--ollama-url` repeats for each GPU
host and `--reserve-ollama-url` for each CPU host, and the GPU hosts embed
together while the CPU hosts serve only when none can. A `query` carrying `semantic` is

A Cargo workspace of three crates:
A Cargo workspace of five crates (`crates/eureka-pipeline` holds the document shapes and keys, `crates/mind-body` the control store, launch primitive and `mind-heartbeat` timeline; the three below are the mind, the daemon and the client):
- `crates/huginn-mind`: storage, identity, admission, and queries and derived

field adds golden lines and never changes an existing one.
Opt-in, against a real store: `stored_documents_read_back` decodes, validates
and keys every stored pipeline document and asserts that it re-encodes to the
stored key, type and payload bytes. Take a copy of the store (the test copies
the file again before opening it, so the copy may be read-only), never open the
live one:
```sh
sudo cp /var/lib/gamecult/huginn/minds/eureka/mind.redb "$SNAP/minds/eureka/mind.redb"
HUGINN_MIND_SNAPSHOT="$SNAP" cargo test -p eureka-pipeline -- --ignored --exact tests::stored_documents_read_back --nocapture
```
The real-store gate is huginn-mind's `#[ignore]` `query::tests::stored_documents_read_back`,
which checks these stored bytes and the read path together (the leaf cannot see the read
path); the Huginn Upgrade runbook in gamecult-ops runs it.

//! 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.

## The container lane
## The heartbeat
`tests/wake.rs` holds one `#[ignore]`d test that runs the real `mind-wake`
binary against the real `huginn-daemon` and a real store at the brake's root,
and asserts that the host a run records is the kernel's hostname. It writes
`/etc/gamecult/minds`, so it runs in a container only (`/.dockerenv`), as root,
with the daemon built beside the binary. A plain `cargo test` skips it, and so
does `cargo mutants`, which therefore reports the three `host()` mutants in
`src/bin/mind-wake.rs` as missed. The lane that kills them:
```sh
cargo build -p huginn-daemon -p mind-body --all-targets \
&& cargo test -p mind-body --test wake -- --include-ignored
```
On Yggdrasil, run it through the verify stopgap in the Rust image
(`ygg-verify.sh <worktree> <rev> rust '<the command above>'`).
Mutation testing of the waker needs the glob form, because `-f src/wake.rs`
finds no mutants in this workspace: `cargo mutants -p mind-body -f
"**/src/wake.rs" -f "**/src/bin/mind-wake.rs"`. The second glob reaches
`host()`, whose mutants only the container lane kills.
`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.
The actuator has its own ignored test, `the_real_bin_finds_her_run_...` in
`tests/self_run.rs`: the real `mind-self-run` against the real daemon with a

//! The heartbeat: the one process that decides which Persona takes a turn and
//! when (rulings `eureka-body:ruling:shared-heartbeat-joint-lever`,
//! `self-declared-urgency-etiquette`, `operator-mention-fills-initiative`).
//!
//! The Minds share one heartbeat and jointly hold the lever to it. Its tempo is
//! `tempo::tally` of every Mind's newest vote, a `Pulse` in her own mind. When a
//! beat falls (the beat has passed since the last one) exactly one Persona takes
//! a turn: `tempo::pick` over the idle, released Minds, by how long each has
//! waited, bent by the urgency she declared for herself, a member addressing her
//! and (a later cut) topics she subscribed to. Two things launch a Persona off
//! the beat: the operator tagging or naming her, once per message, and her own
//! Self run having ended since her last turn. A beat's launch for a Mind whose
//! Self holds briefs (`inbox::derive`) is a Self run claiming them, in place of
//! her Persona turn: a session that ended with a brief open, or a brief admitted
//! after its flush, is never an orphan, and a Self start takes the beat like any
//! launch. A brief an open question holds (raised in it, or in a run that claims it:
//! the repetition breaker's trip holds the claims of the run it belongs to) is
//! neither claimed nor told until that question is answered or withdrawn; other
//! briefs are. Nothing is metered here:
//! no meter and no model call.
//!
//! The heartbeat owns `heartbeat.cc` and is its only writer; Persona units read
//! it. The brakes stay the operator's and are read on every poll. Busy and idle
//! are the slot's: a Persona run whose unit lives (or is within its start grace) is busy; a dead holder is not, and the next launch closes it. The launch is
//! `open_and_launch`, the only opener. The heartbeat never acks a delivery; the
//! Persona turn drains them.
//!
//! A held swarm brake ends the poll before the mind or the mouth is touched.

//! The Self run's credential lease, from the asking side (rulings

//! `eureka-body:ruling:self-run-credential-lease`).
//!
//! The Claude connector is the only holder of the subscription token and the
//! one owner of Self-run admission. A Self run asks it over a unix socket for a
//! lease. The connector answers with one frame and, with it, one descriptor: the
//! read end of a pipe that holds the token, its write end already closed, and
//! the plan's usage windows as it last saw them. Nothing is reserved, billed or
//! settled: the lease lasts while the holder keeps the socket open, so [`Lease`]
//! ends by being dropped, and the connector's only usage-derived refusal is the
//! provider's own.
//!
//! The token is never read here. It travels as a descriptor from the socket to
//! the child's descriptor table and is not in an environment, an argument, a
//! file, a log or any value this module can print.
//!
//! Wire: a `u32` big-endian length, then a MessagePack named map `{kind, value}`
//! of at most [`MAX_LEASE_FRAME_BYTES`]. The connector owns the format; the
//! names in `LeaseMessage` and the structs below are pinned by `lease_client/tests.rs`
//! against the connector's `claude_lease_*` message kinds (lease v2).

# 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.
//!
//! Ruling `eureka-body:ruling:persona-memory-written-not-transcript`: what she
//! must still know when the conversation is gone is written into her mind as
//! typed memory, and a later turn reads it back from there. Open asks and open
//! commitments are not recalled: `persona::render_responsibilities` shows them
//! on every turn beside her stewardships, because they stay in front of her
//! until a resolution closes them. This module owns the cued, ranked remainder
//! and nothing else. It reads only her own mind through `MindPort`; it reads no
//! 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 mind lacks and ends, it never summarises), and stops a child that outlives its flush: an interrupt
//! after the grace, or once the requests of the flush's own turn have grown the
//! prefix by the headroom beyond the prefix the flush was asked at (ruling
//! `eureka-body:ruling:flush-always-gets-a-turn`), then SIGTERM and SIGKILL if
//! the child ignores that. Signals go to the child's process group.
//!
//! One run is one live session (ruling `eureka-body:ruling:live-mind-sessions`).
//! A result ends a turn, not the session. What her Self is asked is derived from
//! her mind (the `inbox` module): an open follow-up with owner `self-run` admitted
//! by her Persona turn is a brief. `drive` is the one writer into her
//! session, and keeps one write outstanding (ruling
//! `eureka-body:ruling:self-session-one-outstanding-write`): the start message,
//! then one line at a time holding the briefs that wait and the flush ask, each
//! sent only after the previous line's echo, mid-turn or idle. The CLI echoes each
//! line it takes into a request (`--replay-user-messages`) and joins lines queued
//! behind one request into a single echo, so the echo is the consumption point
//! only while no second line is in flight. Her Self resolves each brief she
//! answers; the actuator closes none, and a brief she left open is told to her
//! next session. Compaction is off in
//! the CLI (`DISABLE_COMPACT=1`): the organ's own ceiling, flush, end and rehydrate
//! is the only path. The session ends where its cache would be evicted, near the
//! unit's cap, at the context ceiling, or after the flush each of those asks.
//!
//! Every timing decision is one pure function, `decide` (the `decide` module,
//! ruling `eureka-body:ruling:self-run-decider`). `carry` is the loop that turns
//! the operating system's facts into events and executes the actions.
//!
//! The actuator admits nothing, reads neither the brake nor the environment and
//! stops no unit: the gate and the brake hold own those. It never echoes an
//! argument, an endpoint or a stream line. Stream-json is Claude Code's wire, a
//! The child's credential is a lease, not a variable (rulings
//! `eureka-body:ruling:self-runs-through-connector` and
//! `eureka-body:ruling:self-run-credential-lease`): before it starts `claude`,
//! `carry` asks the connector for a lease (`lease_client`) until the unit runtime
//! cap, given to it in seconds (the connector binds the lease to this unit
//! invocation), and the granted descriptor is the only place the token reaches
//! the child. A refusal closes the run Recorded and starts nothing. Nothing is
//! reserved, billed or settled: the lease ends when `carry` drops it, and nothing
//! bounds a run in dollars or in usage; the bounds are `--max-turns`, the unit
//! `RuntimeMaxSec` and the context-ceiling flush. The grant carries the plan usage
//! windows, which go to the child in its start message.
//!
//! The actuator admits run closures and brief closures, nothing else. Every exit of
//! `carry` that leaves her run open resolves it Recorded exactly once (the
//! child's result in the rationale, or that it gave none in the reason). It reads neither the
//! brake nor the environment and stops no unit: the gate and the brake hold own those.
//! It never echoes an argument, an endpoint, a
//! connector's refusal text or a stream line. Stream-json is Claude Code's wire, a
//! foreign owner's JSON: it is parsed into `serde_json::Value` here and nothing
//! parsed is stored.

//! `eureka-body:ruling:flush-always-gets-a-turn`, refined by the decider ruling).

//!
//! 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.
