@shapeshift-labs/frontier-history

Serializable temporal explanation and causality records for Frontier apps.

frontier-history turns event-log entries, CRDT versions, traces, actions, workflow steps, policy decisions, effects, agent/user activity, tests, and replays into one queryable explanation layer.

  }]

Surface

createHistoryTimeline, defineHistoryRecord, compileHistoryTimeline, validateHistoryTimeline, and queryHistoryTimeline normalize temporal evidence records.
explainFieldChange answers why a field changed by collecting direct path records plus related action, workflow, policy, effect, trace, actor, agent, test, replay, and proof records.
planHistoryUndo describes what undo would mean for a path, action, workflow, policy, effect, actor, agent, test, trace, or record scope.
createHistoryWindow and diffHistoryWindows provide replay-window and audit-window comparisons.
createHistoryRegistryGraph and createHistoryProvenanceGraph expose temporal evidence as registry/provenance data.
encodeHistoryJsonl, decodeHistoryJsonl, redactHistoryValue, and createHistoryProof support inspectable replay bundles and AI-readable proof records.

Temporal Explanation Boundary

@shapeshift-labs/frontier-event-log owns bounded logs, checkpoints, cursors, and temporal replay primitives. @shapeshift-labs/frontier-crdt owns CRDT versions, branches, and undo. @shapeshift-labs/frontier-trace owns spans and causal links. @shapeshift-labs/frontier-test owns test/spec evidence. @shapeshift-labs/frontier-inspect owns cross-package inspection bundles.

@shapeshift-labs/frontier-history sits above them as a structural explanation layer. It records that a field change was caused by an action, allowed by a policy, produced by an effect, observed in a trace, initiated by a user/agent, active in a workflow step, and proven by a test or replay without importing those packages.

Benchmarks

Run the package-local benchmark:

npm run bench

Run the comparison/control benchmark:

npm run bench:competitors

The package benchmark writes benchmarks/results/frontier-history-package-bench-latest.json when run from the monorepo. The competitor/control benchmark writes benchmarks/results/frontier-history-competitors-latest.json. Frontier-only package measurements cover timeline creation, compilation, validation, path/action queries, explanation, undo planning, windows, registry/provenance graphs, JSONL, and proof hashing.
