1//! Module declarations.

3/// Asking the workers holding a cancelled run's activities to stop (#233).
4pub mod activity_cancel;
5/// Whether a contract refusal is new information, and therefore worth saying.
6pub mod admission_audit;
7/// Reading one attempt's volatile worker progress note, with typed absence.
8pub mod attempt_progress;
9/// Per-tenant keyed backpressure at the outbox claim (Control-Plane Phase 2,
10/// P2-Q2).
11pub mod backpressure;
12/// Bridge from engine activity dispatch to connected workers.
13pub mod bridge;
14/// Worker contract admission shared by every registration transport.
15pub mod contracts;
16/// Server-side execution of declared action bodies (no worker required).
17pub mod declared_body;
18/// The refusal, and the followable remedy, for retained versions that declare
19/// different bodies for one action.
20pub mod declared_body_ambiguity;
21/// Which retained version's body a declared-command dispatch runs — the
22/// dispatching run's own, not the queue's.
23pub mod declared_body_selection;
24/// A server-run declared command's output, published onto the same transcript
25/// an agent step's is.
26pub(crate) mod declared_body_transcript;
27/// Activity completion handling and dispatch abstractions.
28pub mod dispatch;
29/// Task-envelope generation, idempotency keys, and completion fencing.
30pub mod envelope;
31/// gRPC half of the worker dead-man switch (#197): the transport liveness ping
32/// pushed down a worker's task stream, and the registry its answers correlate
33/// through.
34pub mod grpc_liveness;
35/// Worker heartbeat and liveness tracking.
36pub mod heartbeat;
37/// Server-side mid-run intervention routing (NOI-6): capability gate + attempt
38/// owner resolution + push to the owning worker over a pluggable transport.
39pub mod intervention;
40/// Server half of the liminal connection dead-man switch: the liveness ping/pong
41/// wire pair and the probe that keeps a healthy idle connection's lease alive
42/// while making a dead one loud on both sides.
43#[cfg(feature = "liminal-transport")]
44pub mod liminal_liveness;
45/// Cross-node outbox dispatch over the liminal bus (#13-0 spike, feature-gated).
46#[cfg(feature = "liminal-transport")]
47pub mod liminal_transport;
48/// The transport-neutral vocabulary the dead-man switch's transport halves
49/// share: why a ping failed, and which wire carried it.
50pub mod liveness;
51/// The outbox dead-letter path: retire the row, tell the workflow, record whether it was told.
52pub(crate) mod outbox_dead_letter;
53/// Server-side outbox completion delivery into live workflows.
54pub mod outbox_delivery;
55/// Non-replayed durable-outbox fan-out dispatcher (dormant unless commissioned).
56pub mod outbox_dispatcher;
57/// Live stale-claim outbox reconciler (dormant unless commissioned).
58pub mod outbox_reconciler;
59/// Operator-driven redrive of dead-lettered outbox rows, gated on workflow liveness and on
60/// whether the dead letter's failure was already judged.
61pub mod outbox_redrive;
62/// Terminal-workflow outbox settlement sweep for boot and shard adoption (#253).
63pub mod outbox_settle;
64/// Short-TTL per-namespace placement cache for the dispatcher (Control-Plane
65/// Phase 2, P2-P3).
66pub mod placement_cache;
67/// Unserved-queue honesty at the bridge seam (R1): the four-way taxonomy,
68/// service policies, the two service clocks, and the queryable queue state.
69pub mod queue_service;
70/// Throttled per-namespace quota-state broadcaster for the ops-console live badge
71/// (Control-Plane Phase 2, P2-Q3).
72pub mod quota_broadcast;
73/// Short-TTL per-namespace concurrency-quota cache for the dispatcher's keyed
74/// backpressure (Control-Plane Phase 2, P2-Q2).
75pub mod quota_cache;
76/// Connected-worker registry and handles.
77pub mod registry;
78/// Managed-worker supervision (W-1..W-4): desired state in, contained OS
79/// processes out, with a status surface that is a join of the two.
80pub mod supervisor;
81/// Transport-domain classification and re-dispatch budget for activities whose
82/// worker died before reporting a result.
83pub mod transport_loss;
84/// Server-side `{workspace_root}` expansion for declared action bodies (#139).
85pub mod workspace_root;
