A local execution ledger for trusted task handlers. Register your own action, submit an explicit permission decision, and retain its request, outputs, status, failures and event log.
Node.js 20 or newer. The example runs entirely locally.
npm ci
npm run demoexamples/first-handler.mjs registers a whitespace normalizer. It produces hello ledger, records an invalid-input failure, and denies a third request without calling the handler. Reopening the ledger finds all three runs. The script prints the evidence directory.
Evidence of what was requested and returned belongs to the execution boundary itself. Read the mechanism and implementation notes for the specific boundaries and source links.
“Bounded” refers to an explicit request/policy/evidence boundary; custom JavaScript is trusted and has no enforced wall-clock deadline or OS sandbox. Errors and submitted values enter the local evidence, so use synthetic inputs when sharing a run. To import it elsewhere, build, npm pack, install the resulting local archive, and import createLedger from bounded-execution-ledger.
npm run check and npm test exercise the original behavior, a consumer-created example and concurrent JSON readers.
