GLM Governance Interoperability Analyzer

Validate, analyse, and compare GLM-compliant governance layer manifests

Supports schema_version 1.0, 1.1 and 1.2 · All processing runs in your browser

Paste your governance-layer-manifest.json below. The validator checks structural requirements, controlled vocabulary, timing axis consistency, and schema version compliance. No data is sent to any server.

What is GLM?

The Governance Layer Manifest (GLM) is an open standard for machine-readable boundary declarations. Any governance layer for any high-consequence system can publish a GLM-compliant manifest at a predictable well-known URI — making its claims, non-claims, timing position, and composition posture independently discoverable and verifiable without requiring bilateral documentation or architecture reviews.

GLM does not certify interoperability. It makes boundary declarations machine-readable. This validator checks whether a manifest correctly follows the GLM schema.

⚖️ Compatibility Match

Paste 2 to 6 manifests and analyse their structural compatibility: type composability, timing overlap, manifest-level declarations, and conflict detection.

Controlled Vocabulary Reference

The validator checks against these controlled values. Schema 1.1 adds formation and the source-anchored timing qualifier. Schema 1.2 promotes supersedes to a structured object and adds valid_until at the manifest root.

Valid layer_type values (schema 1.2)

layer_type	Timing surface	Schema
`substrate`	Pre-bind (continuous)	1.0
`witness`	Before-or-at bind	1.0
`boundary`	At bind	1.0
`closure`	Post-bind	1.0
`reviewability`	Post-closure	1.0
`cross_cutting`	Declared per surface	1.0
`formation` NEW 1.1	Pre-bind (source-anchored)	1.1

Valid timing_axis.position values

position	Notes
`pre-bind`	Qualifiers: `continuous` (substrate), `source-anchored` (formation)
`at-bind`	Execution bind-time
`post-bind`	After consequence commits
`post-closure`	After evidentiary closure

Digest verification: The validator checks that manifest_digest.value is present and correctly formatted (64-character SHA-256 hex string). Independent content integrity verification requires the PowerShell commands in the GLM specification. Use Ctrl+Enter to validate or match quickly.
