World-Class Evidence Ledger

Generated at: 2026-06-14

Summary

• decision: evidence-pending
• ready to claim world-class: false
• entries: 4
• source accepted: 0
• accepted: 0
• pending: 4
• human pending: 1
• external pending: 3
• submitted entries: 0
• submitted but pending: 0
• source accepted without valid submission: 0
• invalid submissions: 0
• overclaim guard active: true

This ledger records the current evidence state. It requires both passing source evidence and a validated intake submission with artifact SHA-256 checks before accepting an item. It does not treat planned work, metadata fallback, pending review, or local command-runner output as world-class completion evidence.

Ledger

Evidence	Status	Submission	Category	Current	Next action
provider-holdout	pending	missing	external	model-executed 0; token-observed 0	Run provider-backed holdout cases with real credentials and commit only aggregate evidence.
human-adjudication	pending	missing	human	0/5 decisions; pending 5	Record real A/B choices in the decision template, then regenerate adjudication.
native-permission-enforcement	pending	missing	external	native-enforced targets 0; installer-enforced targets 4	Integrate a real target-client or external installer runtime guard before claiming native permission enforcement.
native-client-telemetry	pending	missing	external	external source events 0; adoption samples 0	Install a real client against the native host and import production metadata-only events.

Provider Holdout

• objective: Collect at least one provider-backed output-eval holdout run with model, timing, and token metadata.
• source status: external_required
• observed state: {"model_executed_count": 0, "timing_observed_count": 10, "token_observed_count": 0, "accepted": false}
• submission state: {"status": "missing", "path": "evidence/world_class/submissions/provider-holdout.json", "artifact_ref_count": 0, "attested_real_evidence": false, "privacy_contract_satisfied": false, "ledger_counts_as_completion": false}

Provenance Requirements

• provider-backed model run
• observed timing
• observed token metadata

Success Checks

• reports/output_execution_runs.json summary.model_executed_count > 0
• reports/output_execution_runs.json summary.timing_observed_count > 0
• reports/output_execution_runs.json summary.token_observed_count > 0
• reports/skill_os2_audit.json item provider-holdout status becomes pass

Privacy Contract

• Do not commit provider credentials or environment dumps.
• The output execution report records output hashes and aggregate run metadata, not raw provider prompts.

Human Adjudication

• objective: Record real blind A/B reviewer decisions before claiming human output review completion.
• source status: human_required
• observed state: {"pair_count": 5, "judgment_count": 0, "pending_count": 5, "invalid_decision_count": 0, "answer_revealed_count": 0, "accepted": false}
• submission state: {"status": "missing", "path": "evidence/world_class/submissions/human-adjudication.json", "artifact_ref_count": 0, "attested_real_evidence": false, "privacy_contract_satisfied": false, "ledger_counts_as_completion": false}

Provenance Requirements

• real reviewer identity
• blind A/B decisions
• answer key unopened until decisions exist

Success Checks

• reports/output_review_adjudication.json summary.pending_count == 0
• reports/output_review_adjudication.json summary.judgment_count == summary.pair_count
• reports/output_review_adjudication.json summary.invalid_decision_count == 0
• reports/skill_os2_audit.json item human-adjudication status becomes pass

Privacy Contract

• Reviewer decisions should not include raw user data or private customer detail.
• Keep the answer key separate until after decisions are recorded.

Native Permission Enforcement

• objective: Prove at least one real target client or external installer runtime guard enforces approved high-permission capabilities.
• source status: external_required
• observed state: {"native_enforcement_count": 0, "metadata_fallback_count": 4, "installer_enforcement_pass_count": 4, "installer_permission_failure_count": 0, "installer_enforcement_ready": true, "residual_risk_count": 4, "failure_count": 0, "accepted": false}
• submission state: {"status": "missing", "path": "evidence/world_class/submissions/native-permission-enforcement.json", "artifact_ref_count": 0, "attested_real_evidence": false, "privacy_contract_satisfied": false, "ledger_counts_as_completion": false}

Provenance Requirements

• real target client or external installer runtime guard
• native enforcement flag or externally accepted guard proof
• residual risk retained for fallback targets

Success Checks

• reports/runtime_permission_probes.json summary.native_enforcement_count > 0
• reports/runtime_permission_probes.json summary.failure_count == 0
• reports/runtime_permission_probes.json summary.installer_enforcement_pass_count records local installer enforcement but does not replace native evidence
• reports/skill_os2_audit.json item native-permission-enforcement status becomes pass

Privacy Contract

• Do not mark native_enforcement true for metadata-only fallbacks.
• Keep residual risks visible for targets that still rely on operator enforcement.

Native Client Telemetry

• objective: Import production metadata-only events from a real external client into the local drift loop.
• source status: external_required
• observed state: {"external_source_events": 0, "adoption_sample_count": 0, "raw_content_allowed": false, "risk_band": "low", "accepted": false}
• submission state: {"status": "missing", "path": "evidence/world_class/submissions/native-client-telemetry.json", "artifact_ref_count": 0, "attested_real_evidence": false, "privacy_contract_satisfied": false, "ledger_counts_as_completion": false}

Provenance Requirements

• real external client source
• metadata-only event
• local-first import path

Success Checks

• reports/adoption_drift_report.json summary.source_types.external > 0
• reports/adoption_drift_report.json summary.adoption_sample_count > 0
• reports/skill_os2_audit.json item native-client-telemetry status becomes pass

Privacy Contract

• Telemetry must remain metadata-only and local-first.
• Do not package reports/telemetry_events.jsonl or any raw prompt, output, transcript, note, or message field.
