Evidence posture

evidence_class: SOURCE_REVIEWED
page_completeness: COMPLETE_WITH_EXTERNAL_GATES
runtime_observation: none attached
independent_reproduction: false
comparative_testing_claim_allowed: false
execution_authority_claim_allowed: false

Published scope

Cedar is an authorization policy language and evaluation model for deciding whether a principal may perform an action on a resource in context.

Canonical source: https://docs.cedarpolicy.com/

Source snapshot posture: official documentation is recorded, but no pinned Cedar release, policy set hash, entity store, request vector, evaluator configuration, raw response, or independent replay receipt is attached.

Native terms

Cedar term	Meaning here	StegVerse relationship
Principal	Actor or identity making a request.	Actor evidence; not current standing by itself.
Action	Requested operation.	Requested action in a Commitment Candidate.
Resource	Object acted upon.	Governed target requiring current scope.
Context	Additional request facts.	Evidence that must be current and attributable.
Authorization response	Permit or forbid decision.	Policy evidence; not execution authority.

Relationship to admissibility

Cedar asks: Is this principal authorized for this action on this resource in this context?
StegVerse asks: May this transition bind consequence now under current authority, delegation, policy, evidence, and recoverability conditions?

Cedar authorization results can become policy and authority evidence for a Commitment Candidate. StegVerse still reconstructs current standing at the consequence boundary.

Observation boundary

No public Cedar execution or StegVerse interoperability observation is claimed.

shared test vector: missing
raw output: missing
timestamp: missing
runtime configuration: missing
source version or hash: missing
replay commands: missing
declared expected outcome: missing
independent reproduction: missing

StegVerse analysis

Criterion	Current result
Identity	Principal identity is supplied to Cedar and must be established elsewhere.
Authority	Permit does not establish current consequence-binding authority.
Policy	Strong overlap when the exact policy set and schema are pinned.
Delegation	Delegation relationships require separate source and validity evidence.
Evidence	Request, entities, schema, policy set, and response can form an inspectable packet.
Replayability	Requires pinned evaluator, schema, policy set, entities, and request.
Reconstructability	Partial until all input and version provenance is retained.
Failure behavior	Missing entities, schema errors, evaluator errors, or ambiguous scope must fail closed.
Interoperability	Cedar response can enter a Commitment Candidate as non-authorizing authorization evidence.

Failure classes

Failure class	Applies	Current evidence posture
Semantic equivalence divergence	Yes	Cedar permit/forbid is not StegVerse ALLOW/DENY.
Authority drift	Yes	Authority can change between evaluation and consequence.
Stale evidence	Yes	Principal, resource, context, and entity relationships can become stale.
Delegation leakage	Yes	Entity relationships may overstate delegated scope.
Replay divergence	Yes	Schema, policy, entity, or evaluator changes may alter results.
Fail-open runtime error	Yes	Evaluation errors cannot become implicit permit.
Policy granularity gap	Yes	Authorization scope may be coarser than the governed transition.

Maintenance and challenge path

Maintenance owner: StegVerse-Labs/admissibility-wiki, External Frameworks audit surface.

A challenge must identify cedar-policy, the disputed claim or mapping, supporting source or artifact, and the requested evidence-class, completeness, or standing change. Evidence strength cannot increase without public inspectable artifacts.

Validation completion criteria

pinned Cedar implementation and version
pinned schema, policy set, and entity store
shared authorization requests
predeclared expected boundaries
raw responses and errors
timestamps and runtime configuration
replay commands
independent rerun receipt
non-claim language preserved

Non-claims

Cedar inclusion does not create certification, equivalence, execution authority, or StegVerse standing. Authorization evaluation is not independently reconstructed commit-time admissibility. This page does not claim live integration or general compatibility.

Next safe build target

Attach one pinned Cedar request packet containing schema, policies, entities, request, raw authorization response, expected StegVerse boundary, replay command, and independent rerun receipt.

This page reflects a bounded admissibility packet. Publication does not create standing. The reflected claim inherits only the standing reconstructable from referenced evidence, authority, and admissibility conditions.
