frontier run agent evidence causal graph workflow provenance

@shapeshift-labs/frontier-run

Append-only distributed run graph, evidence, lane, lease, and decision primitives for Frontier agent work.

frontier-run is the neutral history layer underneath swarm runners and dashboards. It records what happened as immutable causal events, then derives graph projections for lanes, tasks, attempts, artifacts, evidence, patches, verification, decisions, human questions, refs, and dashboard snapshots.

npm: @shapeshift-labs/frontier-run
source: siliconjungle/-shapeshift-labs-frontier-run
license: MIT

Layering Contract

The root package depends only on @shapeshift-labs/frontier and stays safe for Node and browser runtimes. It does not spawn workers, inspect git repositories, run tests, parse source code, open databases, or know about Codex.

Runtime-specific helpers live behind optional subpaths:

@shapeshift-labs/frontier-run/node provides SHA-256 hashing plus JSONL file helpers.
@shapeshift-labs/frontier-run/webcrypto provides an async WebCrypto SHA-256 hash provider.

Higher packages such as swarm planners, runner adapters, Loom, and dashboards should consume and emit run graph records instead of making frontier-run depend on them.

Concepts

A run is an event-sourced graph. Durable truth is the append-only event log; current status is a projection.

RunEvent: immutable actor event with causal parent ids, actor sequence, payload hash, and optional event hash.
RunGraph: materialized nodes and edges derived from events.
LaneNode: scheduling and ownership boundary for tasks.
TaskNode: unit of work with target refs, acceptance, verification, and optional semantic regions.
AttemptNode: one runner execution against a task.
ArtifactNode, EvidenceNode, PatchNode, VerificationNode: reviewable outputs.
DecisionNode: coordinator/admission result such as apply, rerun, reject, record-only, promote, or human-question.
RunSegment and RunRef: Git-like replication helpers for distributed machines without modeling source trees.

Usage

import {
  createRunEvent,
  createRunNodeEvent,
  defineRunLane,
  defineRunTask,
  replayRunEvents,
  summarizeRunLane
} from '@shapeshift-labs/frontier-run';

const created = createRunEvent({
  runId: 'run:release',
  actorId: 'coordinator',
  actorSeq: 1,
  type: 'run.created',
  payload: { goal: 'Publish a package' }
});

const lane = defineRunLane({
  id: 'lane:package',
  title: 'Package release',
  allowedWrites: ['packages/frontier-run/**'],
  maxConcurrency: 1
});

const task = defineRunTask({
  id: 'task:package',
  title: 'Build package',
  laneId: lane.id,
  targetRefs: ['packages/frontier-run/src/index.ts'],
  acceptance: ['npm test passes']
});

const events = [
  created,
  createRunNodeEvent('run:release', 'coordinator', 2, lane, { parents: [created.id] }),
  createRunNodeEvent('run:release', 'coordinator', 3, task, { parents: [created.id] })
];

const projection = replayRunEvents(events);
const summary = summarizeRunLane(projection.run.graph, lane.id);

Node JSONL

import {
  FrontierRunJsonlStore,
  importRunEventBundleJsonl,
  syncRunJsonlStores,
  writeRunEventBundleJsonl
} from '@shapeshift-labs/frontier-run/node';

const store = new FrontierRunJsonlStore('agent-runs/example/events.jsonl');
store.append(created);
const events = store.read();

const bundleEvidence = writeRunEventBundleJsonl('agent-runs/example/export.jsonl', events);
const importEvidence = importRunEventBundleJsonl('agent-runs/example/events.jsonl', 'agent-runs/remote/export.jsonl');
const syncEvidence = syncRunJsonlStores('agent-runs/example/events.jsonl', 'agent-runs/remote/events.jsonl');

The Node store skips duplicate event ids, reports compact sync evidence, and writes bundle files with an atomic local rename by default.

Distributed History

Each event carries causal parents and an actor-local sequence. Multiple machines can append events independently and later merge logs by event id. Concurrent histories do not overwrite each other; admission and coordinator layers can inspect the resulting graph and decide whether to apply, rerun, reject, or promote work.

Use summarizeRunSync to exchange event ids, heads, refs, segments, and actor sequence indexes between machines. compareRunSyncSummaries reports missing event ids and changed refs. createRunSyncExchangePlan turns two summaries into pull/push event, ref, and segment sets. mergeRunSyncExchange applies that plan to two event sets idempotently and reports per-side evidence plus conflicts such as the same actor sequence producing different event ids. The Node helper syncRunJsonlStores applies the same exchange contract to two local JSONL logs.

frontier-run deliberately keeps Git separate. Git remains the source-tree history. Frontier run history records the work, evidence, decisions, and causal context that led to source changes.

Benchmarks

Run package-local measurements with:

npm run bench

The benchmark covers replaying a 1k-event run graph, deriving dashboard summaries for task-heavy runs, and building Merkle-style run segments. Results are Frontier-only package measurements intended to catch local regressions, not competitor comparison claims.
