CS‑1 Generation Protocol

#tags: continuity-substrate, CS-1, identity-invariance, origin-protocol, post-key-security

1. Purpose

This document defines the CS‑1 Generation Protocol: how systems generate a one-time identity invariant (CS‑1) at the moment of human-origin creation, independent of cryptographic keys and traditional signatures.

It is intended for engineers designing origin-aware systems and continuity substrates.

---

2. Design Principles

2.1 One-Time Per Origin Event

CS‑1 must be generated exactly once per human-origin creation event.

2.2 Identity-Invariant

CS‑1 must encode a stable reference to human identity without exposing secrets or relying on keys.

2.3 Non-Replayable, Non-Transferable

CS‑1 must not be reusable across unrelated artifacts or transferable between identities.

2.4 Format-Agnostic

CS‑1 must not depend on artifact format (pdf, docx, html, etc.).

3. Inputs to CS‑1 Generation

• AuthorIdentityRef — stable identity root (e.g., LinkedX Hub URI).
• OriginTimestamp — ISO 8601 timestamp of origin event.
• OriginContext — optional description of the artifact’s purpose.
• ArtifactSeed — optional stable seed derived from artifact (e.g., hash of initial content).

---

4. CS‑1 Generation Steps (Conceptual)

Step 1: Capture Origin Event

• Detect that a human has created an artifact for the first time.
• Record:
  • authorIdentityRef,
  • originTimestamp,
  • originContext.

Step 2: Derive ArtifactSeed (Optional)

• Compute a stable seed from the artifact’s initial state:
  • e.g., hash(initialBytes) or canonicalTextHash.

Step 3: Construct Origin Vector

• Build an internal origin vector:
  • OriginVector = { authorIdentityRef, originTimestamp, originContext, artifactSeed }.

Step 4: Generate CS‑1

• Apply a deterministic, non-key-based mapping from OriginVector to CS‑1.
• CS‑1 must:
  • be unique per OriginVector,
  • be stable over time,
  • not reveal sensitive identity details.

Representation example:

• CS1-<opaque-immutable-identifier>

Step 5: Persist CS‑1

• Store CS‑1 in:
  • CAF‑1 identityInvariant.cs1,
  • Continuity Registry keyed by CS‑1.

5. Properties of CS‑1

5.1 Immutability

Once generated, CS‑1 must never change.

5.2 Unclonability

No two distinct origin events may share the same CS‑1.

5.3 Imitation Resistance

Synthetic systems must not be able to generate CS‑1 that passes verification as a human-origin event.

5.4 Independence from Cryptographic Keys

CS‑1 must not be derived from:

• private keys,
• certificates,
• PKI,
• PQC schemes.

6. Verification of CS‑1

6.1 Inputs

• CS‑1,
• authorIdentityRef,
• originTimestamp,
• optional OriginVector components.

6.2 Checks

• CS‑1 exists in Continuity Registry.
• CS‑1 is bound to the expected authorIdentityRef.
• CS‑1 is associated with a valid originTimestamp.
• CS‑1 has not been reused across unrelated artifacts.

---

7. Implementation Notes

7.1 Representation

• CS‑1 may be represented as:
  • opaque string,
  • UUID-like identifier,
  • structured token.

7.2 Storage

• Stored in CAF‑1 and Continuity Registry.
• Indexed by:
  • cs1,
  • authorIdentityRef.

7.3 Privacy

• CS‑1 must not expose raw identity attributes.
• Mapping from OriginVector to CS‑1 must be non-invertible.

---

8. Conclusion

CS‑1 Generation Protocol defines how identity invariants are created at origin events, ensuring one-time, immutable, non-transferable signatures that anchor human continuity without relying on cryptographic keys.
