# ONE Market E18.0 — External Qualification Campaign Authority

E18 is a fail-closed authority for acquiring and admitting evidence produced outside the ONE Market requester boundary. It does not contain a fabricated laboratory report, accreditation identifier, physical-region campaign, module validation, or independent audit.

## Canonical status

`PASS_WITH_EXTERNAL_EVIDENCE_ACQUISITION_GATE_READY_AND_EXTERNAL_EXECUTION_OPEN`

The canonical production decision is `BLOCKED_EXTERNAL_EVIDENCE_REQUIRED` because the demonstration contains zero external reports, zero external laboratories, and zero executed physical regions.

## What is executable

- signed and expiring campaign challenges;
- binding to source, build, deployed-artifact, and toolchain digests;
- accreditation anchors with exact evidence-class scopes;
- anchor expiry and revocation;
- signed evidence reports and independent witnesses;
- append-only hash-linked chain of custody;
- physical-region independence policy;
- research/production separation;
- exact missing-evidence diagnostics;
- TLC and SMT positive/mutant verification;
- deterministic binaries and verification receipts.

## External work still required

Production admission requires genuine externally controlled evidence covering the nine required classes, at least three independent laboratory organizations, at least two witness organizations, and a physical campaign using three independent providers, failure domains, and administrators. Accreditation and recognition status must be checked against current authoritative external directories.

## Verify the executable package

```bash
unzip ONE_Market_E18_Executable_Evidence_v18_0.zip -d e18-evidence
cd e18-evidence/ONE_Market_E18_External_Qualification_Campaign_Implementation_v18_0
PYTHONHASHSEED=8181 python3 verification/verify_e18.py
```

The generated receipt must be byte-identical to `verification/ONE_Market_E18_Verification_Receipt_v18_0.json`.

## Rebuild the document

```bash
unzip ONE_Market_E18_Complete_Source_v18_0.zip -d e18-source
cd e18-source
./ONE_Market_E18_Reproducible_Build_v18_0.sh
```

The build script regenerates the monolithic TeX source from the E17 authority and E18 implementation, then compiles the PDF with pdfLaTeX.

## No-certification clause

E18 is a campaign authority and evidence gate. It is not an ISO/IEC 17025 accreditation, ILAC MRA recognition, NIST laboratory accreditation, CMVP validation, CAVP certificate, physical multi-region qualification, or independent security audit.
