Cryptographically Governed Context Continuity
Your systems authenticate. They don't govern what happens after — and when a deletion request arrives, none of them can prove the data is gone. STACCR™ is architected to make context propagation governed and erasure cryptographically provable across every system that ever touched it.
Reduce regulatory exposure
Designed to turn GDPR Art. 17 and CCPA deletion obligations into a signed, regulator-ready certificate — not a deletion log and a hope.
Deploy AI with confidence
Agents and automations can propagate context without your organization inheriting unprovable deletion liability.
Cut audit cost
Architected so 'where did this data go and who touched it' is a query, not a quarter-long forensic project.
Market timing: EU AI Act record-keeping obligations are phasing in. Agent-to-agent context sharing is multiplying propagation paths. The gap between "we deleted it" and "we can prove it" is becoming a board-level question.

What STACCR™ Is Not
- Not an identity provider
- Not a data warehouse or system of record
- Not a CRM or CDP
- Not AI memory hoarding
- Not a consent banner tool
STACCR™ preserves governed continuity, provenance, and revocation without taking ownership of the underlying data.
It sits between your identity layer and everything downstream — it governs context, it doesn't hoard it. It complements your IdP and data stack; it doesn't replace them.
The Problem
What Breaks Without Governed Context
01
AI systems make decisions with context they can't explain or audit
02
Consent changes don't propagate — they accumulate as regulatory exposure
03
Erasure requests require proof of inaccessibility — a deletion log is not evidence
How It Works
The Request Lifecycle
Every context event flows through three governed layers — entry, evaluation, and exit. Nothing moves untracked.
Identity assertion received
Provider-agnostic token minted, claims extracted. Sensitive data stays in the source system — only AES-256-GCM encrypted references cross the platform.
Token evaluated against tenant policy
Context enriched under policy, propagated to registered adapters via the event broker. Every propagation event is recorded to the registry.
On erasure request — cryptographic lifecycle close
DEK destroyed in the customer's KMS. Propagation registry queried for every adapter that received the token. Signed ErasureAcknowledgment collected from each. Proof certificate issued.
Every request is governed at entry, enriched under policy, and accountable at exit — nothing moves untracked.
Provable Erasure
Cryptographic Proof, Not a Deletion Log
Irreversibility enforced at KMS policy level, not application layer
Five-Step Destruction Sequence
Erasure initiated
Data-subject request · consent withdrawal · retention expiry · regulatory order
Per-user DEK destroyed in customer's KMS
All key versions across the key lifecycle destroyed
Test decryption attempted — confirmed to failProof moment
This is the proof moment: the platform demonstrates it cannot recover the data
Every adapter returns signed HMAC-SHA256 ErasureAcknowledgment
Each system in the propagation registry signs for its own compliance
Signed erasure certificate issued
Immutable audit ledger entry with adapter confirmation hashes

Regulatory Alignment
- GDPR Art. 17 / Art. 5(2) / Art. 32
- EU AI Act Art. 12–13
- CCPA §1798.105
- HIPAA §164.312
When a regulator asks "prove it's gone," the answer is a cryptographically signed certificate covering every system that ever held the data — not a deletion log.
The Adapter Contract
ErasureAcknowledgment Schema
Every system that integrates with STACCR™ signs a binding contract. Accountability is built into the protocol.
// ErasureAcknowledgment — returned by every adapter within the SLO window { "erasure_request_id": "uuid-v4", "adapter_id": "uuid-v4", "token_id": "tok_...", "purge_completed_at": "2026-06-11T17:42:09Z", "decryption_confirmed_failed": true // MUST be true — false = SEV incident "adapter_audit_log_ref": "https://...", "adapter_signature": "hmac-sha256:..." }
Encrypted references only
Adapters never receive plaintext context — only AES-256-GCM encrypted token references.
Registry registration within 500ms of token receipt
Every adapter propagation is immediately recorded so the erasure registry is complete at deletion time.
Revocation listener with signed acknowledgment on erasure
Adapters must implement the revocation protocol and return a signed HMAC-SHA256 ErasureAcknowledgment within the SLO window.
Adapter contract specification available to design partners → Apply for access
Every integrated system signs for its own compliance — accountability is built into the protocol, not promised in a contract appendix.
Verifiability Rubric
The Standard We Hold Ourselves To
Ask this of any vendor, including us.
Attestation-by-trust can't answer these. Attestation-by-cryptography can. The gap between them is the entire problem this platform is designed to close.
1. Who holds the keys?
Customer-held keys (BYOK). KEK in customer HSM, per-user DEK in customer KMS. STACCR™ is architected to never hold the encryption keys to your data.
2. Can you destroy your own access to my data?
DEK destruction removes STACCR™'s ability to decrypt. The platform is designed so that after erasure, it cannot recover the data — the KMS policy enforces this, not application logic.
3. Show me a decryption failing after deletion.
The five-step destruction sequence above includes a live test-decryption confirmation step. The platform attempts to decrypt after DEK destruction and records the confirmed failure as part of the erasure certificate.
4. What does leaving you cost — in time, money, and stranded value?
30-Day Exit Commitment (in effect from GA): any customer can leave with a signed erasure certificate and zero stranded value within 30 days.
Our exit guarantee, in effect from GA
Signed erasure certificate + zero stranded value within 30 days. This is a business commitment, not a spec target. Requires founder sign-off before GA publish.
5. Can a third party verify any of this without trusting you?
Certificate signing key policy and third-party verification path are P0 open items. We don't have a complete answer yet — see the Engineering Roadmap.
We publish our incomplete answers alongside our complete ones. Pre-GA honesty is the only credible form of proof.
The STACCR™ Framework
Six Capabilities, One Outcome
Context that moves where it's needed and disappears when it must.
Govern propagation
Tokenized Propagation
Moves signed token references instead of raw data across system boundaries.
Without this
Sensitive payloads replicate unchecked across every downstream system.
Context Orchestration
Coordinates context-aware workflows across services, agents, and enterprise platforms.
Without this
Each system reconstructs fragmented state independently — with no consistency guarantees.
Prove provenance
Secure Architecture
Identity-anchored, zero-trust design with policy-governed propagation and encrypted transport.
Without this
Context flows without access controls, making policy enforcement impossible to audit.
Auditable Provenance
Traceable lineage for every context event, access, transformation, and policy decision.
Without this
'Where did this data go?' becomes a forensic project instead of a query.
Enforce lifecycle
Context Continuity Lifecycle
Preserves context integrity from capture through propagation, update, and expiration.
Without this
Context continuity is lost at every system boundary — agents and workflows start from scratch.
Revocation & Erasure
Cryptographic key destruction with per-adapter confirmation and signed erasure certificates.
Without this
Deletion requests are best-effort API calls — legally exposed and technically unverifiable.
Six capabilities, one outcome: context that moves where it's needed and disappears when it must.
