Framework-Native Scope

Sigstore provides software-artifact signing and verification infrastructure using identity-bound certificates, transparency logging, and associated verification tooling. Its native contribution is evidence about artifact origin, signature validity, certificate identity, and log inclusion.

Evidence Provenance

Evidence class	Current evidence	Status	Missing fields
Official framework source	Sigstore documentation	present	immutable snapshot or version hash
Implementation source	No selected release or binary attached	missing	client version, commit, binary hash
Observed behavior	No signing or verification run	missing	artifact, signature, certificate, log proof, raw output
Reproduced behavior	No independent rerun	missing	commands, environment, second result
StegVerse analysis	Bounded crosswalk	present	common fixture execution

Relationship to Admissibility

Sigstore asks: Is this artifact associated with the represented signing identity and transparency evidence?
StegVerse Admissibility asks: May this transition bind consequence now under current authority and policy?

Signature and transparency evidence can strengthen origin, integrity, and reconstruction review. They do not independently establish action scope, delegation, or consequence-binding authority.

Execution Authority Boundary

valid signature != authorized action
certificate identity != current delegation
transparency-log inclusion != admissibility
artifact integrity != permission to execute or deploy

Observation Boundary

Pinned client: none
Signed artifact fixture: none
Certificate and transparency proof: none
Raw verifier output: none
Timestamped runtime environment: none
Independent replay: none

No verification or interoperability result is claimed.

StegVerse Analysis

Criterion	Current result
Identity	A signing identity may be evidenced, subject to certificate and issuer validation.
Authority	Identity evidence does not prove current authority for the requested transition.
Policy	Verification policy and trust roots must be explicit and current.
Delegation	The signer, deployer, and executing actor may be different entities.
Evidence	Signatures, certificates, and log proofs can improve reconstructability.
Replayability	Requires pinned client, trust roots, artifact, signature, certificate, proof, and command.
Reconstructability	Depends on retained log proofs, trust material, and artifact digests.
Commit-time validity	Requires separate policy, delegation, and target-action evaluation.
Failure behavior	Invalid, absent, expired, or unverifiable evidence must fail closed.

Failure Classes

Failure class	Applies	Notes
Semantic equivalence divergence	yes	Signature validity may be mistaken for authorization.
Authority drift	yes	A signer may no longer have current standing.
Stale evidence	yes	Certificates, trust roots, and revocation posture change.
Delegation leakage	yes	Signer identity may be improperly inherited by a deployer.
Replay divergence	yes	Different clients or trust roots may change verification.
Source-claim mismatch	yes	Public claims may exceed what the signature or log proves.

Validation Completion Criteria

pin a Sigstore client and trust configuration
publish an artifact, signature, certificate, and transparency proof
capture raw verification output and timestamp
publish expected result and replay commands
complete an independent rerun
route the result into a Commitment Candidate fixture

Non-Claims

Sigstore is not a StegVerse canonical formalism. Signature verification and transparency inclusion are not transition admissibility, current delegation, execution authority, certification, or general compatibility.

Challenge Path

A challenge must identify the artifact, signature, certificate, trust root, log proof, disputed claim, and requested correction. The page advances only through inspectable evidence and re-evaluation.

Next Safe Build Target

Publish one pinned signing-and-verification fixture with raw output, trust configuration, immutable hashes, replay commands, and an independent rerun.

This page reflects a bounded admissibility packet. Publication does not create standing.
