Abstract

The Ultimate Ingestible Schema Language (UISL) is a deterministic schema governance architecture for machine-interpreted artifacts. Unlike conventional structured data formats, UISL requires strict formal grammar compliance, canonical byte construction, SHA-256 cryptographic hashing, ED25519 digital signature verification, append-only hash chaining, and custody enforcement as mandatory conditions of validity. Each artifact is deterministically parsed, canonically rendered, cryptographically validated, and immutably linked to prior state, ensuring reproducibility, authority verification, and continuity of meaning across independent systems. UISL establishes a fail-closed validation model in which structural integrity, cryptographic proof, and historical continuity are mathematically enforced. This technical note provides an informational disclosure associated with a filed patent application.

Series Information

The Ingestible Schema Language (ISL) Series

The Ingestible Schema Language (ISL) series is a structured family of deterministic schema systems designed to govern machine-interpreted communication with reproducibility, auditability, and continuity.

The series includes:

1. ISL (Ingestible Schema Language)

ISL is a structured schema language designed to standardize interpretation across AI systems, institutions, and human operators.

Core characteristics:

• Deterministic field structure

• Explicit policy encoding

• Structured governance constraints

• AI-readable and human-readable

ISL provides controlled interpretation but does not intrinsically bind cryptographic authority or chain continuity.

2. CISL (Classical ISL)

CISL represents structured ISL implementations emphasizing traditional deterministic schema constraints within institutional or regulatory environments.

Focus:

• Controlled language structure

• Policy clarity

• Operational reproducibility

3. QISL (Quantum ISL)

QISL extends ISL into higher-order structured representations, focusing on complex multi-domain schema interactions while preserving deterministic structure.

Focus:

• Advanced structured representation

• Multi-domain encoding

• Controlled semantic layering

4. CMD (Conscious Memory Drive)

CMD is the custody and continuity layer supporting ISL systems.

CMD enforces:

• Append-only storage

• Retention governance

• Revocation without deletion

• Historical audit integrity

CMD ensures long-term preservation of schema artifacts.

5. UISL (Ultimate Ingestible Schema Language)

UISL represents the deterministic cryptographic evolution of the ISL series.

UISL integrates:

• Formal ABNF grammar

• Canonical byte construction

• SHA-256 cryptographic hashing

• ED25519 digital signatures

• Append-only hash chaining

• Mandatory custody enforcement

Where ISL governs structure and policy, UISL governs structure, authority, and immutable continuity.

Relationship Within the Series

ISL family systems provide structured deterministic schema design.

UISL extends the series by binding structure to cryptographic proof and chain-based continuity.

CMD operates across the series as the custody and preservation layer.

Together, the ISL series forms a unified framework for reproducible, authority-verifiable machine governance.

Methods

Methods

1. System Overview

The Ultimate Ingestible Schema Language (UISL) operates through a deterministic multi-layer validation process. Artifact validity requires sequential execution of grammar enforcement, canonical construction, cryptographic verification, continuity validation, and custody recording.

All steps are mandatory and fail-closed.

2. Artifact Construction Method

Step 1: Field Population

A UISL artifact is constructed using a predefined ordered set of required fields.

Field order is fixed and must not vary.

Step 2: Grammar Validation

The artifact is parsed using a strict ABNF-defined grammar.
Unknown fields, duplicate fields, or incorrect ordering result in immediate invalidation.

3. Canonical Byte Construction Method

Step 3: Canonical Selection

A defined subset of fields (e.g., SPEC through TSA) is selected for canonicalization.

Step 4: Canonical Rendering

Each field is rendered in the format:

KEY:VALUE

Fields are joined using a single newline character (\n) with no trailing newline.

Encoding is ASCII only.

Step 5: Canonical Byte Output

The resulting byte sequence becomes the canonical string used for cryptographic operations.

4. Cryptographic Integrity Method

Step 6: Hash Computation

SHA-256 is applied to the canonical byte string.

Step 7: Hash Verification

The computed hash is compared to the declared HASH field.
Mismatch results in invalidation.

5. Cryptographic Authority Method

Step 8: Public Key Resolution

The KEY field identifies the public key (KID).

Step 9: Signature Verification

ED25519 verification is performed using the canonical byte string and resolved public key.

Signature mismatch results in invalidation.

6. Chain Continuity Method

Step 10: Chain Reference Evaluation

If CHAIN equals GENESIS, artifact is first in sequence.

Otherwise:
CHAIN must equal the SHA-256 hash of the previously validated artifact.

Mismatch results in invalidation.

7. Custody Enforcement Method (CMD)

Step 11: Append-Only Recording

Upon validation, the artifact is stored in append-only custody storage.

Stored elements include:

• Raw artifact

• Canonical hash

• Validation verdict

• Timestamp

• Prior hash reference

Step 12: Retention Enforcement

No overwrite or deletion is permitted. Revocation requires additive entry.

8. Validation Outcome

The validator returns one of the following:

• VALID

• INVALID_PARSE

• INVALID_SCHEMA

• INVALID_HASH

• INVALID_SIGNATURE

• INVALID_CHAIN

• POLICY_BLOCKED

No partial acceptance is permitted.

9. Alternative Implementations

The method may be implemented in:

• Local AI nodes

• Enterprise validator services

• Federated distributed validators

• Secure enclave-based signing environments

Cryptographic primitives may be substituted with equivalent secure algorithms without departing from the system architecture.
