The cores are open. The control plane is a roadmap.

Digest, Strata, and Lethe are available today as open-source cores and executable proofs. No hosted control plane is generally available yet. The capabilities below describe the design-partner roadmap, not a shipping service.

Design partners roadmap

The proposed hosted control plane for one production system. These capabilities are targets for design-partner validation.

  • Ambiguity telemetry: what your users actually meant
  • Provenance registry & drift dashboards
  • Persistent Lethe with scheduled sweep policies
  • Signed erasure receipts, exportable for audit
  • Slack/pager alerts on drift & ledger anomalies

Not available future scope

Potential fleet-wide scope for organizations where forgetting is a compliance requirement.

  • Unlimited systems, SSO, on-prem control plane
  • Right-to-be-forgotten SLAs with receipt registry
  • Unlearning-readiness audits for weights & indexes
  • Custom repair passes & schema extensions
  • A named human who answers the phone

Questions people actually ask

Why is the core free?

Because a manifesto you have to pay to practice isn't a manifesto, it's a paywall. The cores are small, auditable, and dependency-free on purpose. Fleet persistence, registries, and dashboards are roadmap work that will be priced only if and when they become a real service.

What counts as "one system"?

One deployed application with its own seam, ontology, and memory — however many models it calls. A monorepo with three products is three systems; one product with five model providers is one.

Do erasure receipts satisfy GDPR/right-to-be-forgotten?

Receipts are evidence of deletion, not legal advice — your counsel maps them to your obligations. What the design provides: predicate erasure with per-store receipts today; a durable release registry and auditor-readable exports are design-partner roadmap, not shipping software. On Canopy, deletion SLAs are contractual.

Can I pilot just one organ?

Yes. A design-partner conversation can focus on one boundary—ambiguity, ontology drift, or erasure—without implying that a hosted product already exists.

Not sure which organ you're missing?

Forty-five minutes: you describe the system, we tell you whether it's dying as a hoarder, an amnesiac, or a museum — and what the first month of fixing that looks like.
