Modules

admission_audit

Whether a contract refusal is new information, and therefore worth saying. Whether a contract refusal is NEW INFORMATION, and therefore worth saying.

attempt_progress

Reading one attempt’s volatile worker progress note, with typed absence. Reading the volatile worker progress note of one attempt — honestly.

backpressure

Per-tenant keyed backpressure at the outbox claim (Control-Plane Phase 2, P2-Q2). Per-tenant keyed backpressure at the outbox claim (Control-Plane Phase 2, P2-Q2).

bridge

Bridge from engine activity dispatch to connected workers. NIF bridge dispatcher that routes run_activity calls to connected workers.

contracts

Worker contract admission shared by every registration transport. Shared worker registration admission against durable package contracts.

declared_body

Server-side execution of declared action bodies (no worker required). Server-side execution of declared action bodies.

declared_body_ambiguity

The refusal, and the followable remedy, for retained versions that declare different bodies for one action. The refusal an operator reads when retained package versions disagree about an action’s declared body — and the remedy it names.

declared_body_selection

Which retained version’s body a declared-command dispatch runs — the dispatching run’s own, not the queue’s. Which retained version’s body a declared-command dispatch runs.

dispatch

Activity completion handling and dispatch abstractions. Push dispatch for remote activity workers and result handoff to the engine contract.

envelope

Task-envelope generation, idempotency keys, and completion fencing. Activity task-envelope generation and completion fencing.

heartbeat

Worker heartbeat and liveness tracking. Heartbeat window tracking and lost-worker failure surfacing.

intervention

Server-side mid-run intervention routing (NOI-6): capability gate + attempt owner resolution + push to the owning worker over a pluggable transport. Server-side mid-run intervention routing (NOI-6).

liminal_liveness

Server half of the liminal connection dead-man switch: the liveness ping/pong wire pair and the probe that keeps a healthy idle connection’s lease alive while making a dead one loud on both sides. Server half of the liminal connection dead-man switch: the liveness probe.

liminal_transport

Cross-node outbox dispatch over the liminal bus (#13-0 spike, feature-gated). Cross-node outbox dispatch over the liminal bus (LSUB push transport).

outbox_delivery

Server-side outbox completion delivery into live workflows. Server-side outbox completion delivery callback.

outbox_dispatcher

Non-replayed durable-outbox fan-out dispatcher (dormant unless commissioned). Non-replayed background dispatcher for the durable fan-out outbox.

outbox_reconciler

Live stale-claim outbox reconciler (dormant unless commissioned). Live reconciliation for stranded claimed outbox rows.

outbox_redrive

Operator-driven redrive of dead-lettered outbox rows, gated on workflow liveness and on whether the dead letter’s failure was already judged. Operator-driven redrive of dead-lettered outbox rows.

outbox_settle

Terminal-workflow outbox settlement sweep for boot and shard adoption (#253). Terminal-workflow outbox settlement sweep (#253).

placement_cache

Short-TTL per-namespace placement cache for the dispatcher (Control-Plane Phase 2, P2-P3). Short-TTL in-process cache of per-namespace placement directives, read by the non-replayed outbox dispatcher (Control-Plane Phase 2, P2-P3).

queue_service

Unserved-queue honesty at the bridge seam (R1): the four-way taxonomy, service policies, the two service clocks, and the queryable queue state. Module declarations.

quota_broadcast

Throttled per-namespace quota-state broadcaster for the ops-console live badge (Control-Plane Phase 2, P2-Q3). Throttled per-namespace quota-state broadcaster for the ops console live badge (Control-Plane Phase 2, P2-Q3).

quota_cache

Short-TTL per-namespace concurrency-quota cache for the dispatcher’s keyed backpressure (Control-Plane Phase 2, P2-Q2). Short-TTL in-process cache of per-namespace concurrency quotas, read by the non-replayed outbox dispatcher’s keyed backpressure (Control-Plane Phase 2, P2-Q2).

registry

Connected-worker registry and handles. Connected-worker registry keyed by worker-pool address and activity type.

supervisor

Managed-worker supervision (W-1..W-4): desired state in, contained OS processes out, with a status surface that is a join of the two. Module declarations.

transport_loss

Transport-domain classification and re-dispatch budget for activities whose worker died before reporting a result. Transport-domain failure classification for activities whose worker died.

workspace_root

Server-side {workspace_root} expansion for declared action bodies (#139). Server-side {workspace_root} expansion for declared action bodies.
