A start (ruling `eureka-body:ruling:persona-turn-drains-deliveries`) reads the +//! instance brake and the swarm brake once, and a held brake ends it +//! dead before the mind, the chat or the lease is touched. Otherwise it +//! adopts the Persona run the heartbeat opened for it; a start with no such run +//! opens none and ends `NoRun`, because only the heartbeat opens Persona turns. +//! +//! Then it carries her session (rulings `eureka-body:ruling:persona-session-full-sandbox` +//! and `eureka-body:ruling:live-mind-sessions`): per conversation it lends a +//! credential (`lease_client`), starts one `claude` under bubblewrap in her sandbox and hands it to +//! `self_run::session::drive`, the Self's own driver, with her chat as the inbox. +//! A session is one conversation, the public rooms together or one direct message room. It +//! ends when another conversation's delivery is the oldest unanswered, when decide's flush ends it +//! (the context ceiling, the cache, the unit's cap) or when a result cannot be acted on; the start +//! goes on to the next conversation until nothing is pending or the cap's rotation margin is +//! reached, and closes the run once. +//! +//! Her instructions (doctrine, persona state, the campaigns in force) are the session's system +//! prompt, read once per process. What reaches her in the stream is one line per batch of +//! deliveries: the messages, her responsibilities, what her mind recalls, the plan windows the +//! lease granted and the tempo. A batch is the deliveries the CLI echoed since the last result; +//! each result is constrained to one `PersonaReply` schema (ruling +//! `eureka-body:ruling:persona-reply-typed-by-schema`), decoded into that one type and acted on: +//! each `say` is sent, each `remember` becomes a memory in her own mind and each `settle` +//! closes an open commitment or ask there (ruling `eureka-body:ruling:persona-memory-written-not-transcript`), +//! with her vote in the same admission; `start_self_run` admits its brief as a follow-up and opens +//! a Self run that claims it (ruling `eureka-body:ruling:self-run-brief-claimed-follow-up`), +//! taking an open item on when it names one; and only then are the deliveries acked. A reply that +//! cannot be decoded sends nothing, acks nothing and is told back to her with the refusal; the +//! third in a row ends the session. Any other failure sends nothing further, acks nothing and +//! ends the start; the run is closed Recorded with the failure, so the breaker and the next wake +//! see it. Nothing is acked that was not answered, and a repeat of a send carries the same +//! request id, so a start that dies between a send and its ack repeats no message. +//! +//! The reply is decoded, never scanned: text that is not one `PersonaReply` is a refused +//! result. Chat, persona state and trace are ports; the chat transport is `chat_rudp::RudpChat`, +//! wired by the binary. Inside her sandbox her session has the full toolset, a shell and the web +//! included; her effects in the world are only what `act` does with a result. +//! +//! The organ admits only her memories and the resolutions that settle or take on +//! an ask, a follow-up, a run's closing resolution, her own `Pulse` (the tempo +//! she votes for and the urgency she declares) and, through `open_and_launch`, a +//! Self run.

The Self-run actuator: one `claude` child carries her one open Self run. -//! -//! `carry` finds her run (the one in-force Self run operated by the mind, read -//! through `launch::holders`: the run is the grant), starts `claude` with the -//! fixed argument list, writes the start message and watches the child's -//! stream-json output. It counts the main thread's requests, asks for the flush -//! once when the context prefix reaches the ceiling (ruling -//! `eureka-body:ruling:self-lifecycle-flush-rehydrate`: a Self run admits what -//! 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 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 counts the main thread's requests, asks for the flush +//! once when the context prefix reaches the ceiling (ruling +//! `eureka-body:ruling:self-lifecycle-flush-rehydrate`: a Self run admits what +//! 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 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.

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.

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); (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 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`).
