+Run `world-class-preflight` before assigning external or human work. It checks local files, redacted environment readiness, human/external prerequisites, and source-evidence blockers without accepting evidence or printing secrets.
+
 The generated intake report also includes an `operator_checklist` for each pending evidence item. Use it to find the template path, target submission path, preparation command, validation command, required provenance, success checks, and privacy boundary before asking a reviewer or external operator to submit evidence.
 
 The submission kit command creates editable JSON drafts plus a local README for an external operator or human reviewer. Those drafts keep `template_only: true` and do not count as evidence until the real run or review exists, the packet is edited truthfully, every artifact ref points to a local aggregate evidence file with a matching `sha256`, and `world-class-intake` validates it.

+# World-Class Evidence Preflight
+
+Generated at: `2026-06-16`
+
+## Summary
+
+- decision: `collection-preflight-blocked`
+- ready to claim world-class: `false`
+- preflight counts as evidence: `false`
+- credential value exposed: `false`
+- collection ready: `1`
+- collection blocked: `3`
+- source checks: `6` pass / `13` total
+
+This preflight report checks whether an operator can start collecting the remaining external or human evidence. It never accepts evidence, prints secret values, or changes the world-class ledger.
+
+## Evidence Items
+
+| Evidence | Status | Intake | Review | Next action |
+| --- | --- | --- | --- | --- |
+| `provider-holdout` | `blocked` | `awaiting-submission` | `awaiting-submission` | Set OPENAI_API_KEY in the operator shell; never commit or print the value. |
+| `human-adjudication` | `ready-for-human-review` | `awaiting-submission` | `awaiting-submission` | Assign a real reviewer identity before claiming human adjudication. |
+| `native-permission-enforcement` | `blocked` | `awaiting-submission` | `awaiting-submission` | Attach a real target-client or external installer runtime guard; metadata fallback is not enough. |
+| `native-client-telemetry` | `blocked` | `awaiting-submission` | `awaiting-submission` | Install a real Browser, Chrome, IDE, or provider client that emits metadata-only events. |
+
+## Provider Holdout
+
+- status: `blocked`
+- ledger: `pending`
+- submission: `evidence/world_class/submissions/provider-holdout.json`
+
+### Prechecks
+
+| Check | Kind | Current | Status | Next action |
+| --- | --- | --- | --- | --- |
+| Output eval cases | `file` | `present` | `pass` | Keep output holdout cases available before provider execution. |
+| Provider runner | `file` | `present` | `pass` | Use the provider runner instead of the local command runner for model-backed evidence. |
+| Provider credential | `env` | `not-set` | `missing` | Set OPENAI_API_KEY in the operator shell; never commit or print the value. |
+| Provider model | `env` | `not-set` | `optional` | Optionally set YAO_OUTPUT_EVAL_MODEL; the runbook defaults to gpt-4.1-mini. |
+
+### Source Checks
+
+| Check | Current | Expected | Status | Next action |
+| --- | --- | --- | --- | --- |
+| Provider model run | `0` | `>0` | `blocked` | Run provider-backed output-exec with real credentials. |
+| Timing observed | `10` | `>0` | `pass` | Provider execution should record timing metadata. |
+| Token usage observed | `0` | `>0` | `blocked` | Provider execution should return non-estimated token usage. |
+
+## Human Adjudication
+
+- status: `ready-for-human-review`
+- ledger: `pending`
+- submission: `evidence/world_class/submissions/human-adjudication.json`
+
+### Prechecks
+
+| Check | Kind | Current | Status | Next action |
+| --- | --- | --- | --- | --- |
+| Blind review kit | `file` | `present` | `pass` | Open the blind review kit and record real reviewer choices. |
+| Decision template | `file` | `present` | `pass` | Fill winner_variant values with real A/B decisions. |
+| Human reviewer | `human` | `external-human-action` | `human-required` | Assign a real reviewer identity before claiming human adjudication. |
+
+### Source Checks
+
+| Check | Current | Expected | Status | Next action |
+| --- | --- | --- | --- | --- |
+| Review pairs exist | `5` | `>0` | `pass` | Generate the blind A/B review pack. |

+| Judgments complete | `0` | `==pair_count` | `blocked` | Every pair needs one valid human judgment. |
+| No invalid decisions | `0` | `==0` | `pass` | Fix malformed winner/confidence entries. |
+
+## Native Permission Enforcement
+
+- status: `blocked`
+- ledger: `pending`

+| Runtime probes | `file` | `present` | `pass` | Refresh runtime permission probes after packaging changes. |
+| Native guard | `external` | `external-integration-required` | `external-required` | Attach a real target-client or external installer runtime guard; metadata fallback is not enough. |
+
+### Source Checks
+
+| Check | Current | Expected | Status | Next action |
+| --- | --- | --- | --- | --- |
+| Native enforcement | `0` | `>0` | `blocked` | Collect real target-client or external runtime guard proof. |
+| Probe failures | `0` | `==0` | `pass` | Runtime permission probes must stay clean. |
+| Installer support | `True` | `true` | `pass` | Installer enforcement is supporting evidence, not native proof. |
+
+## Native Client Telemetry
+
+- status: `blocked`
+- ledger: `pending`
+- submission: `evidence/world_class/submissions/native-client-telemetry.json`
+
+### Prechecks
+
+| Check | Kind | Current | Status | Next action |

+| Native telemetry host | `file` | `present` | `pass` | Use the native host to receive metadata-only client events. |

+| External client | `external` | `external-integration-required` | `external-required` | Install a real Browser, Chrome, IDE, or provider client that emits metadata-only events. |
+
+### Source Checks
+
+| Check | Current | Expected | Status | Next action |
+| --- | --- | --- | --- | --- |
+| External events | `0` | `>0` | `blocked` | Import at least one metadata-only event from a real client. |
+| Adoption sample | `0` | `>0` | `blocked` | Telemetry must include adoption outcome evidence. |
+| Raw content blocked | `False` | `false` | `pass` | Telemetry must stay metadata-only. |
+
+## Boundary
+
+- Environment variables are reported only as `set` or `not-set`; values are never printed.
+- Human-required and external-required states are operator actions, not accepted evidence.
+- The world-class ledger remains the source of truth for `ready_to_claim_world_class`.
