Governance-Ledger

Governance-Ledger turns governed source text and authority contracts into deterministic, reviewable, publishable governance authority. It is best understood as Governance Compiler + Semantic Derivation Infrastructure.

Ledger is not an AI or general-purpose policy interpreter, workflow automation layer, orchestration engine, cloud operations layer, or runtime execution system. It does not guess meaning from policy language. It recognizes only a published deterministic sentence grammar, preserves everything else as informational, unsupported, or requiring resolution, derives deterministic governance meaning, gates publication, preserves lineage, and makes governance authority replayable.

What It Provides

  • Governance normalization from source text into canonical governance statements.
  • Semantic diagnostics for ambiguous, conflicting, incomplete, or unsafe authority.
  • Governance compilation reports with coverage, diagnostics, statement traces, and report hashes.
  • Publication gating so governance authority cannot be published when blocking diagnostics are present.
  • Provenance chains from source governance to compilation reports to published authority contracts.
  • Publication manifests and contract registries with integrity hashes.
  • Lineage verification for authority artifacts.
  • Replay tooling for compilation and admissibility evidence.
  • Deterministic snapshots, rollback artifacts, diffs, and review lifecycle state.
  • Canonical semantic artifacts for previews, diff impacts, review packets, and authority bundles.
  • Governance chronology replay and replay diff infrastructure for reconstructing authority posture from append-only events.
  • Canonical schemas for generated governance, diagnostics, replay, publication, review, registry, snapshot, and semantic artifacts.

Why This Exists

Governance used by runtime systems must be deterministic, inspectable, and reproducible. Human governance language can enter the system, but publication authority should only come from normalized statements, explicit diagnostics, approved reviews, canonical compilation reports, and traceable provenance.

Governance-Ledger exists to make that path auditable:

Governance Source
  -> Normalized Statements
  -> Semantic Diagnostics
  -> Governance Compilation Report
  -> Human Review and Approval
  -> Published Authority Contract
  -> Semantic Derivation Artifacts
  -> Manifest, Registry, Snapshot
  -> Authority Bundle
  -> Lineage Verification and Replay

Core Concepts

Governance normalization

Ledger classifies governance statements and converts supported language into canonical policy structures. Unsupported or ambiguous language remains visible as diagnostics; it is not silently converted into executable authority.

Semantic diagnostics

Diagnostics identify governance risks such as missing authority, overlapping thresholds, duplicate roles, weak normalization coverage, and publication-blocking compiler issues. Diagnostics are structured artifacts with stable codes, severity, domains, and publication impact.

Governance compilation reports

Compilation reports bind source governance identity, normalized statement traces, coverage metrics, diagnostics, compiler summaries, and a deterministic report_hash. They are evidence objects, not log output.

Publication gating

Publishing requires an approved review and generated policy that passes compiler-ingestion validation. Blocking diagnostics prevent publication. Published contract, manifest, registry, deployed review, and snapshot artifacts are written as one transaction.

Lineage verification

Published authority contracts include governance_authority_lineage.v1 linking the authority to source governance and compilation report hashes. Ledger can verify that lineage independently.

Semantic governance compilation

Ledger owns deterministic governance interpretation after authority has been structured. Semantic derivation modules convert authority_contract.v1 and related publication artifacts into canonical meaning artifacts without invoking Guard, Cloud, simulation, runtime evaluation, or admissibility execution.

The canonical semantic artifacts are:

  • governance_impact_preview.v1: governance summary, enforcement behavior, consequences, lifecycle implications, and example governed outcomes.
  • authority_diff_impact.v1: semantic impact of authority changes, including escalation, operational, lifecycle, and replay continuity implications.
  • governance_review_packet.v1: review-ready packet binding authority, preview, optional diff impact, optional evidence, review context, immutable hashes, and explicit non-goals.
  • authority_bundle.v1: publishable governance object binding authority contract, publication manifest, semantic artifacts, review packets, lineage, provenance, schema compatibility, and immutable inputs. Customer-authored bundles may declare the additive customer_policy_provenance_complete_v1 profile; older bundles remain readable as provenance-incomplete.

Replayability

Replay tooling reproduces compilation evidence from source governance and can replay admissibility decisions against authority and execution state. Replay failures produce diagnostics rather than silent disagreement.

Deterministic governance operationalization

Ledger records governance state transitions and publication artifacts with deterministic identifiers, hashes, normalized paths, immutable publication outputs, and rollback-capable snapshots.

Governance chronology replay

Ledger can replay append-only governance events to reconstruct governance meaning at a point in time. Chronology replay reconstructs active authority, lineage state, continuity posture, replay posture, projection freshness, governance health, and operational summaries without calling Guard or Cloud.

Ledger can also compare replay states across cutoffs with governance_replay_diff.v1, making governance posture changes over time deterministic and reviewable.

What It Is Not

Governance-Ledger is not:

  • AI policy interpretation.
  • Legal advice or legal reasoning.
  • A workflow automation product.
  • An orchestration engine.
  • A cloud governance operations service.
  • A runtime mutation executor.
  • A replacement for CRI-CORE Contract Compiler semantics.
  • A replacement for Waveframe Guard runtime enforcement.
  • A system that bypasses Guard admissibility.
  • A system that infers unsupported governance meaning.

Install

python -m venv venv
.\venv\Scripts\Activate.ps1
pip install governance-ledger

Ledger relies on installed package contracts for integration behavior:

  • cricore-contract-compiler>=0.4.0 (the first released compiler contract with exact/prefix target rules)

The base install does not install Waveframe Guard. Install the tested optional admissibility integration explicitly when Ledger should delegate execution replay to Guard:

pip install "governance-ledger[guard]"

The guard extra selects waveframe-guard==0.15.0, matching the released Guard compatibility metadata that tests Guard 0.15.0 with Ledger 0.5.0; the Ledger v0.6.0 release matrix revalidates that same Guard version. Applications such as Cloud can instead inject a compatible evaluator without installing Guard in Ledger's environment:

from governance_ledger.replay import replay_admissibility

result = replay_admissibility(
    authority_contract=authority,
    execution_state=execution_state,
    evaluator=my_admissibility_evaluator,
)

Existing callers that omit evaluator retain Guard-backed replay after installing the guard extra. Without either an evaluator or that extra, Ledger raises an actionable GuardIntegrationUnavailableError. Ledger prepares, publishes, replays, and verifies authority evidence; Guard evaluates runtime admissibility. Enforcement logic remains outside Ledger.

Local checkout path resolution is not part of production behavior.

Plain Customer-Policy Service

Cloud and other callers can use the stable, pure service boundary without a repository checkout, filesystem state, subprocess, Cloud import, or Guard import:

from governance_ledger import (
    finalize_customer_policy_authority,
    interpret_customer_policy,
)

draft = interpret_customer_policy(
    exact_policy_bytes,
    source_policy_id="repository-change-policy",
    source_revision="rev-17",
    authority_id="repository-change-authority",
    authority_version="6.0.0",
)

publication = finalize_customer_policy_authority(
    draft,
    resolutions=[],
    approval_id="approval-001",
    approved_by="policy-owner@example.com",
    approved_at="2026-08-29T13:58:00Z",
    committed_by="policy-owner@example.com",
    committed_at="2026-08-29T13:59:00Z",
    publication_id="publication-001",
    published_by="publisher@example.com",
    published_at="2026-08-29T14:00:00Z",
)

interpret_customer_policy_text(...) is a convenience wrapper that performs only text.encode("utf-8"). Neither entry point normalizes newlines, Unicode, whitespace, or punctuation. Finalization reconstructs the draft from its embedded exact bytes and identities, so caller-edited classifications, rules, mappings, spans, or hashes are rejected.

The v0.6 grammar recognizes only these case-sensitive, period-terminated forms:

  • <subject> may be made only by <plural-role>. — required actor role; the plural role must end in s, which is removed before lower-case hyphenation.
  • Agents may modify <exact-path>.
  • Agents must not modify <exact-path>.
  • Agents may modify files under <prefix-path/>.
  • Agents must not modify files under <prefix-path/>.
  • <Transfers|Purchases|Payments|Invoices|Requests> <above|over|at least|below|under> $<number> require <role> approval.
  • Requester and approver must be separate. (an initial The is also accepted).

Exact and prefix targets must be repository-relative forward-slash paths. Absolute, drive-qualified, traversal, backslash, control-character, unsafe empty-segment, and malformed trailing-slash targets fail closed. Duplicate and overlapping allow/deny meanings become bounded ambiguities; Ledger never invents precedence.

Normative text outside this exact grammar is unsupported. Non-normative text is informational. Normative statements containing terms such as normally, appropriate, unless necessary, or other documented ambiguous qualifiers are requires_resolution. When removing exactly one recognized modifier produces exactly one valid grammar rule, Ledger offers that specific enforcement consequence alongside unsupported and informational; otherwise only the two non-enforcement choices are available. A resolution can select only an interpreter-produced option. Unsupported text remains visible in the approved interpretation.

Statement classification is complete once every source statement has one classification; interpretation remains incomplete while any ambiguity is unresolved. A draft is ready for finalization only when no ambiguity remains and at least one enforceable rule is present. Informational/unsupported-only drafts remain inspectable but cannot publish, and Ledger invents neither allow-all nor implicit deny-all semantics.

Finalization requires explicit resolution, approval, commit, and publication identities and canonical UTC timestamps. Chronology is enforced as every resolved_atapproved_atcommitted_atpublished_at, with equality allowed and supplied resolution order preserved. Required actor roles, conditional approval thresholds, target rules, and separation-of-duties constraints remain distinct when projected into the installed CRI-CORE Contract Compiler. Finalization then returns the validated interpretation, resolution set, approval record, semantic commit, compiler input, canonical compiled contract, impact preview, manifest, provenance-complete authority_bundle.v1, and publication_receipt.v1. Source revision and authority version are independent and are hash-bound by publishes_as.

Command Workflow

Generate normalized governance drafts and validation artifacts:

governance-ledger run policies/

Check publication readiness:

governance-ledger check generated/

Approve a reviewed governance artifact:

governance-ledger approve reviews/finance_policy.review.json --actor governance-team

Publish approved governance authority:

governance-ledger publish reviews/finance_policy.review.json

Inspect published authority:

governance-ledger list contracts
governance-ledger resolve finance-policy@0.1.0
governance-ledger show contracts/finance-policy-0.1.0.contract.json

Verify authority lineage:

governance-ledger verify-lineage --contract contracts/finance-policy-0.1.0.contract.json

Replay source governance into compilation evidence:

governance-ledger replay-authority `
  --source policies/finance_policy.txt `
  --report reviews/finance_policy.deployed.review.json `
  --contract contracts/finance-policy-0.1.0.contract.json

Replay execution admissibility:

governance-ledger replay-execution `
  --contract contracts/finance-policy-0.1.0.contract.json `
  --execution-state execution_state.json

The CLI form uses the optional Guard adapter and therefore requires the guard extra. Programmatic callers may use evaluator injection instead.

Generate semantic governance artifacts:

governance-ledger preview `
  contracts/finance-policy-0.1.0.contract.json `
  --output generated/finance-policy.preview.json

governance-ledger diff-impact `
  --old contracts/finance-policy-0.1.0.contract.json `
  --new contracts/finance-policy-0.2.0.contract.json `
  --output generated/finance-policy.diff-impact.json

governance-ledger review-packet `
  --authority contracts/finance-policy-0.1.0.contract.json `
  --preview generated/finance-policy.preview.json `
  --output generated/finance-policy.review-packet.json

governance-ledger authority-bundle `
  --authority contracts/finance-policy-0.1.0.contract.json `
  --manifest contracts/finance_policy.publication_manifest.json `
  --preview generated/finance-policy.preview.json `
  --output generated/finance-policy.authority-bundle.json

publish now emits the canonical local authority bundle automatically. The authority-bundle command remains available for deterministic derivation and inspection workflows.

Artifact Layout

policies/      source governance text
generated/     normalized policy drafts and validation artifacts
reviews/       review, approval, compilation, and deployment evidence
contracts/     immutable published authority contracts, manifests, registry
snapshots/     deterministic governance state snapshots
schemas/       canonical JSON schemas
governance_ledger/semantics/
               canonical semantic derivation layer

Publication produces:

  • contracts/<contract-id>-<version>.contract.json
  • contracts/<contract-id>-<version>.authority-bundle.json
  • contracts/<contract-id>-<version>.publication-receipt.json
  • contracts/<policy>.publication_manifest.json
  • contracts/index.json
  • reviews/<policy>.deployed.review.json
  • snapshots/<snapshot-id>.json

Publication artifacts use normalized POSIX-style paths such as contracts/finance-policy-0.1.0.contract.json, even on Windows.

The registry entry for a published authority includes deterministic bundle identity:

{
  "authority_ref": "finance-policy@0.1.0",
  "contract_hash": "sha256:...",
  "bundle_path": "contracts/finance-policy-0.1.0.authority-bundle.json",
  "bundle_hash": "sha256:...",
  "lifecycle_state": "active"
}

governance-ledger resolve <authority-ref> accepts only explicit versioned references such as finance-policy@0.1.0 and resolves them to the canonical local authority bundle.

Semantic artifacts are deterministic derivations. They may be exported under generated/ for review or packaging, but they are not runtime evaluations and do not change execution outcomes.

Example Normalization

Source governance:

Transfers above $1M require manager approval.
Requester and approver must be separate.
All transfer approvals must be recorded for audit purposes.

Normalized policy excerpt:

{
  "contract_id": "finance-policy",
  "contract_version": "0.1.0",
  "authority": {
    "required_roles": ["manager"],
    "separation_of_duties": true
  },
  "approvals": {
    "required": [
      {
        "role": "manager",
        "condition": {
          "field": "amount",
          "operator": ">",
          "value": 1000000
        }
      }
    ],
    "thresholds": [
      {
        "field": "amount",
        "operator": ">",
        "value": 1000000,
        "requires_role": "manager"
      }
    ]
  },
  "artifacts": {
    "required": ["approval_audit_record"]
  }
}

Diagnostics and Gates

Validation artifacts and review artifacts include structured warnings and compiler diagnostics. A diagnostic may be informational, warning-level, or publication-blocking.

Examples of publication-blocking conditions:

  • Ambiguous authority, such as approval without a named approving role.
  • Low governance normalization coverage.
  • Overlapping approval thresholds.
  • Duplicate or conflicting approval requirements.
  • Compiler schema violations.
  • Missing or mismatched provenance lineage.

governance-ledger check generated/ exits non-zero when validation contains error-severity diagnostics.

Lineage and Integrity

Published authority contracts include lineage:

{
  "lineage": {
    "schema_version": "governance_authority_lineage.v1",
    "source_hash": "sha256:...",
    "compilation_report_hash": "sha256:...",
    "review_id": "review-finance_policy"
  }
}

Publication manifests, receipts, and registries carry source and report hashes so consumers can verify the authority chain without trusting local build state.

Semantic artifacts also carry immutable input hashes. Authority bundles bind contract, manifest, preview, optional diff impact, and optional review packets into a single publishable governance object that Cloud can ingest, validate, store, replay, and operate without reconstructing governance context. Local publication receipts are deterministic Ledger evidence for the publication record; hosted Cloud receipts can preserve the same authority durably but are not interchangeable with local publication state.
