+- **F21 What the mind can attribute a document to, at the mind-launch head `8dee875`.** Read
+  from a throwaway worktree on 2026-10-09 (Imagination `imagination-launch-r3`).
+  - A receipt's provenance is `{ faculty, agent, session, tool }`, all declared by the writer.
+    No selection alias reads `session`, so attributing by session means scanning headers.
+    `open_and_launch` admits a run with session equal to its run label
+    (`crates/mind-body/src/launch.rs:205`). Nothing makes a Self run's later admissions carry
+    that label: the Self organ is not built.
+  - Citations are typed content. A `cites` selection with no role over every schema is
+    supported and tested (`crates/huginn-mind/src/query.rs:1499`). A run's header facts carry
+    `turn`, `operated_by` and `claims` (query.rs:139).
+  - The breaker at 8dee875 scans every header in the mind, newest first, back to the oldest
+    counted run (`crates/mind-body/src/queue.rs:210`). Its cost grows with the whole mind.
+  - `Mind::admit` takes `&mut self` (`crates/huginn-mind/src/admission.rs:81`), so
+    admissions are serialized. The run rule is `run_claims_rule` (admission.rs:537-547). It is
+    applied when a run opens (admission.rs:526-529) and when a withdrawal reinstates a closed
+    run (admission.rs:685-694). It checks claims only.
+  - `MindRefusal` is huginn-mind's (`crates/huginn-mind/src/refusal.rs`), published in
+    `schemas/cultnet/huginn.mind_response.v1.schema.json` and pinned by
+    `published_wire_schemas_match_derivation` (wire.rs:276). The leaf's `PipelineRefusal` has
+    five variants (`crates/eureka-pipeline/src/lib.rs:59-65`) and is not where admission's rules
+    refuse.
+  - `Effective::Released { cadence, run_cap_usd }` is a public struct variant
+    (`crates/mind-body/src/control.rs:117-120`), so any caller can build one without reading the
+    store. `ControlState::effective` is called only by `read_effective` (control.rs:192-197).
+  - huginn-mind's `fixtures::run` builds an in-force SelfRun with `operated_by: Mind`
+    (fixtures.rs:331-342). The claim tests open several of them at once
+    (admission.rs:1987-2015).
+  - `Slug::validate_slug` and `Label::validate_label` are public
+    (crates/eureka-pipeline/src/lib.rs:287, 386). `RunTurn` and `RunOperator` spell their
+    variants through `Debug`, which is also their `NAMES` (lib.rs:436-452).

+### Who decides one live run, and who ends a dead one
+
+Soul's verdict `cut-mind-launch.s1` found the one-live rule decided in two places, neither
+of them sound. `open_and_launch` read for a live run and then admitted later, so two
+interleaved launches both passed. The MCP admit door checked nothing, so a second live run
+committed directly. Mind-launch r2 had accepted the race, on the grounds that only a Persona
+turn starts Self runs. Neither the waker nor the Persona tool exists, so nothing enforced that.
+
+- **Admission owns the rule.** Batches are serialized (`&mut self`, F21), and admission already
+  owns the neighbouring exclusivity, `AlreadyClaimed`. The rule is "at most one in-force run
+  with `operated_by: Mind` per instance and turn". That is the ruled option's own text: "one
+  run cap in flight per turn kind", with Persona turns one at a time in every option. So the
+  waker's own PersonaTurn Busy check goes too. The refusal is a new `MindRefusal` variant,
+  `AlreadyLive { run }`. `PipelineRefusal` is the leaf's document-shape vocabulary and stays at
+  five variants (F21).
+- **The primitive owns liveness.** Admission cannot see units. A run whose unit died, never
+  started, or lost its admit answer would otherwise hold the turn's slot forever. Before it
+  checks anything else, `open_and_launch` reads the turn's live holders of hers. It closes each
+  one whose unit is not alive and whose admission is older than the 120 s start grace, and
+  answers `Busy` for any that remain. That early `Busy` only refuses, so it cannot make a
+  second live run; admission stays the authority for races and for direct admits. The waker's
+  sweep in mind-wake r2 was a second owner of the same judgement, and r3 deletes it.
+- **Recorded, not Withdrawn.** The breaker treats a withdrawn run as one that never ran. A Self
+  unit that crashes every time would then never trip, and would loop at the dial's cadence.
+  Closing a dead run as `Recorded` makes a crash an empty ended run, so three in a row raise a
+  question. Prior art does the same: a Kubernetes Job counts a failed pod against
+  `backoffLimit`, and systemd's `StartLimitBurst` counts failed starts. A start that fails
+  inside the launch, before any unit ran, is still Withdrawn.
+- **Lease prior art, and why there is no lease.** A Kubernetes Lease or an etcd lease makes
+  liveness a renewal the holder must keep sending. Here the host's unit table already is that
+  signal (`systemctl is-active`), so a renewal would be a second owner of the fact
+  (`run-is-the-grant`). The cost is that a dead run is only noticed when the slot is next
+  wanted. That is also the only moment its being in force matters, apart from the queue's
+  claimed-by view. That view is wrong for at most one launch attempt, because the next Self
+  launch closes the dead holder first.
+- **Writer-declared `operated_by`.** A writer that declares `Operator` escapes the rule. This is
+  the gap already owned by follow-up `operator-authority-needs-operator-credential`, which must
+  land before autonomous Self runs. No second guard is added here.
+
+### What the breaker counts
+
+The ruling's rider says a run is empty when it "admitted nothing but their own run". The
+built breaker counted every document admitted anywhere in the mind during a run's window.
+Under `every-wake-a-run` a PersonaTurn run always lands in that window, so the breaker could
+never trip (finding `breaker-counts-every-document`). Two attributions are available (F21):
+
+- **By receipt session.** It is declared by the writer. Nothing makes a Self run's subagents use
+  the run label yet. No alias reads it, so the whole-mind scan stays.
+- **By citation of the item (chosen).** Citations are typed content, and one role-less `cites`
+  selection on the item returns the runs that claim it, the questions raised in it, and every
+  report, resolution, follow-up or deferral that names it. That replaces the whole-mind scan
+  with a bounded one. A productive run on a cut spec admits a report, a question, a superseding
+  revision or a follow-up. Each of those cites the item, and most also take the item out of the
+  queue. Work a Self run does that names another item is not progress on this one.
+- **The reset is a question, not a ruling.** A ruling that answers the breaker question cites the
+  question, not the item. Counting only runs admitted after the newest question raised in the
+  item makes the trip itself the boundary. A reopened item then starts a fresh count, and the
+  10-of-50 rule cannot trip again after one more run. Every trip gets its own key,
+  `breaker-<run label>`, so a second trip raises a second question.
+- **Counted runs are hers.** Only `operated_by: Mind` runs count, because the breaker guards her
+  loop (`merge-gate-own-soul`), not the operator's sessions.
