# World-Class Evidence Ledger Generated at: `2026-06-15` ## Summary - decision: `evidence-pending` - ready to claim world-class: `false` - entries: `4` - source accepted: `0` - source checks: `6` pass / `13` total - source blocked: `7` - 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}` - source checks: `1` pass / `3` total - 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 ### Source Runbook - `YAO_OUTPUT_EVAL_MODEL=gpt-4.1-mini OPENAI_API_KEY= python3 scripts/yao.py output-exec --provider-runner openai --timeout-seconds 60` - `python3 scripts/yao.py skill-os2-audit . --generated-at ` - Copy evidence/world_class/templates/provider-holdout.intake.json to evidence/world_class/submissions/provider-holdout.json and fill only real evidence fields. - `python3 scripts/yao.py world-class-intake . --submissions-dir evidence/world_class/submissions` ### Source Evidence Checks | Check | Current | Expected | Status | | --- | --- | --- | --- | | Provider model run | `0` | `>0` | `blocked` | | Timing observed | `10` | `>0` | `pass` | | Token usage observed | `0` | `>0` | `blocked` | ### Completion Assertions - 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}` - source checks: `2` pass / `4` total - 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 ### Source Runbook - `python3 scripts/yao.py output-review-kit --write-template` - Open reports/output_review_kit.md and choose A or B for each pair without opening the answer key. - `python3 scripts/adjudicate_output_review.py --write-template` - Edit reports/output_review_decisions.json with winner_variant values and reviewer metadata. - `python3 scripts/yao.py output-review` - `python3 scripts/yao.py skill-os2-audit . --generated-at ` - Copy evidence/world_class/templates/human-adjudication.intake.json to evidence/world_class/submissions/human-adjudication.json and fill only real evidence fields. - `python3 scripts/yao.py world-class-intake . --submissions-dir evidence/world_class/submissions` ### Source Evidence Checks | Check | Current | Expected | Status | | --- | --- | --- | --- | | Review pairs exist | `5` | `>0` | `pass` | | No pending decisions | `5` | `==0` | `blocked` | | Judgments complete | `0` | `==pair_count` | `blocked` | | No invalid decisions | `0` | `==0` | `pass` | ### Completion Assertions - 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}` - source checks: `2` pass / `3` total - 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 ### Source Runbook - Implement or connect a real target client or external installer runtime guard that blocks undeclared network, file_write, or subprocess capabilities. - Update the generated target adapter only when the guard is actually enforced by that target. - `python3 scripts/yao.py package . --platform openai --platform claude --platform generic --platform vscode --output-dir dist --zip` - `python3 scripts/yao.py install-simulate . --package-dir dist --install-root dist/install-simulation` - `python3 scripts/yao.py runtime-permissions . --package-dir dist` - `python3 scripts/yao.py skill-os2-audit . --generated-at ` -

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}` - source checks: `1` pass / `3` total - 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 ### Source Runbook - `python3 scripts/telemetry_native_host.py . --write-launcher /tmp/yao-telemetry-host.sh --write-manifest /tmp/yao-telemetry-host.json --allowed-origin chrome-extension:///` - Install the generated native messaging manifest for the real client and send at least one accepted skill_activation or skill_output event. - `python3 scripts/yao.py telemetry-import . --input-jsonl .yao/telemetry_spool/external_events.jsonl` -
