# OKF v0.2 adds trust signals

**[Google Cloud](https://daily.dev/sources/gcp)** · 11 min read · 0 upvotes · 0 comments

## Summary

Open Knowledge Format v0.2 introduces trust signals for AI-agent-written knowledge bundles. The update adds five new frontmatter field families to answer: where did this come from (provenance via `sources`), how trustworthy is it (`generated`/`verified` trust tiers), is it still current (`stale_after`/`status`), and was a reported number computed the sanctioned way (a new `Attested Computation` concept type with executor/attester mechanics). All new fields are opt-in and backward-compatible with v0.1. The release also ships an updated reference agent that emits trust signals on generation, a static visualizer surfacing trust tiers, updated sample bundles, and a Knowledge Catalog demo showing round-trip preservation of trust metadata.

## Questions this post answers

### What new fields does OKF v0.2 add for tracking trust and provenance in knowledge bundles?

OKF v0.2 adds a sources field for provenance (author, usage_count, last_modified), generated and verified fields for trust tiers (unverified, machine-confirmed, human-reviewed), stale_after and status for freshness and lifecycle, and a new Attested Computation type with executor and attester fields to mechanically verify computed values. All fields are optional and a v0.1 bundle still validates unchanged.

_Teams designing agent-safe data pipelines can track spec changes like OKF's trust fields on daily.dev._

### How does OKF's Attested Computation verify that an agent computed a number the sanctioned way?

An Attested Computation declares a sanctioned SQL query with fixed parameters, runs it through an executor that returns a receipt containing the job_id, executed SQL, and result, then a deterministic attester canonicalizes and compares the executed SQL against the sanctioned version. If a table name, filter, or join was altered, the canonical forms differ and the consumer refuses to display the value, since the check never uses an LLM.

_Anyone hardening agent-generated analytics against silent query tampering can follow attestation patterns like this on daily.dev._

### Is OKF v0.2 backward compatible with OKF v0.1 bundles?

Yes, v0.2 is an additive, backward-compatible minor version bump. Only two renames occurred: timestamp was superseded by generated.at, and the body's Citations list was superseded by the sources field, and in both cases a v0.2 consumer can still fall back to reading the v0.1 form. A v0.1 bundle drops into a v0.2 consumer unchanged.

_Engineers planning a spec upgrade can weigh compatibility trade-offs like these before migrating on daily.dev._
