From ffcd2666c5848feb88515c23b986c9ebbcc0f1e3 Mon Sep 17 00:00:00 2001 From: Meta Vens Date: Sun, 1 Nov 2026 13:45:37 +0100 Subject: [PATCH] Restore LF line endings on the files the WIP commits converted to CRLF The base is LF; the wip commits rewrote whole files as CRLF, hiding the real diff. Content unchanged.

The Persona organ: one start of `mind-persona@` carries her live session. -//! -//! 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.

The Persona organ: one start of `mind-persona@` carries her live session. +//! +//! 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 +//!

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 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.
