//! Steward — the dreaming consolidator
//! (docs/design/agent-memory-architecture.md §8.5).
//!
//! ## Containment shape: a pipeline, not a member (deliberate)
//!
//! §8.5 sketches the steward as a service identity, but a live mob member
//! is currently uncontainable: meerkat-mob members carry the full tool
//! surface of their profile, and the capability-gated tool-authorization
//! layer §8.4 waits on does not exist yet (the same verified finding that
//! shaped the Distiller's detached harness). So the dream is a
//! **deterministic multi-phase pipeline of structured LLM calls**: the
//! shell owns the loop, the model owns the judgment, and containment is
//! structural — the model gets NO tools, only rendered context and a
//! strict output grammar, and every write flows through the staged-commit
//! validator (§8.4 crash semantics, §10.2 lattice) unchanged.
//!
//! Phases:
//! - **Orient** (deterministic): per-scope counts, floor pressure, and the
//!   active manifest, assembled host-side.
//! - **Gather** (bounded agentic): the signal packet (proposals queue,
//!   quarantine queue, usage/injection stats, recent distillates, recent
//!   tombstones, pending harvests, open loops) plus an evidence-request
//!   round — the model may return structured read requests (record bodies
//!   by id, transcript ranges) which the shell fulfills within pinned
//!   limits (≤[`MAX_GATHER_REQUESTS`] requests over
//!   ≤[`MAX_GATHER_ROUNDS`] rounds). "Look only for things you already
//!   suspect matter."
//! - **Usage audit** (§9.2): a sample of the injection ledger plus bounded
//!   evidence windows; load-bearing verdicts update
//!   `UsageStats::judged_useful_count` via `UsageEvent::JudgedUseful` and
//!   inform the consolidate phase's ranking.
//! - **Consolidate**: the model emits a `StagedMutationBatch`-shaped op
//!   list plus verdicts (proposals, quarantine, open loops,
//!   contradictions) and the working-set ordering. Strict parse, one
//!   repair retry, shell-side sanitation, then stage→validate→commit.
//! - **Harvest** (exit interviews): retired identities recorded by the
//!   retire/delete hooks are harvested — durable knowledge proposed into
//!   mob scope, the rest tombstoned per retention judgment.
//!
//! ## Commit discipline
//!
//! Ops commit as a small number of atomic groups (consolidate ops; one
//! batch per accepted proposal; one per quarantine verdict; one per
//! harvested identity; one final rank batch), each a single-transaction
//! staged commit with per-op audit rows. A dream that dies mid-run leaves
//! at most GC-able stage tokens and already-committed *complete* groups —
//! never a half-applied batch. Quarantine-promotes into Mob scope are
//! staged but **not** committed: a gating pending entry is enqueued and
//! only the operator's approval commits the token
//! ([`PromotionGateResolver`]).
//!
//! ## Scheduling
//!
//! MobKit's scheduling subsystem can only target mob members/sessions
//! Scheduling: since 0.7.21 the dream runs as a durable host-runnable
//! schedule occurrence (`schedule_wiring::steward_dream_runnable_host`);
//! the guarded tokio interval loop survives only as the fallback on
//! gateways with no schedule host. Cadence stays in the scheduling
//! subsystem's interval grammar (`*/6h`).
