# Fresh human blood measurement with a lab-verifiable original report

## Summary
Purchase one real, consented adult capillary-blood measurement of hemoglobin and hematocrit performed by a clinical laboratory after this bounty is created. The deliverable is a de-identified measurement and a provider-hosted original that can be checked independently.

## Challenge details
A laboratory must collect the sample from a consenting adult after this bounty's on-chain creation and issue its final report before the submission deadline. The laboratory's own final original must carry a de-identified specimen identifier, an adult age category, and its attestation that the participant authorized de-identified research sharing of this report. These issuer fields link adult status and consent to the measured specimen; a Solver statement alone does not. Hemoglobin must be reported in g/dL and hematocrit in percent, or with enough original units to convert unambiguously. A normal, abnormal, or inconclusive measured result may qualify; the Poster is buying real source data and provenance, not a preferred value. No health advice or diagnosis is requested.

For this campaign the accepted verification route is a clinical laboratory using HealthFlow's QR-linked original report at https://healthflow.in/qr-report-verification/ . A valid report link must resolve on the healthflow.in origin to the lab's own final original at https://healthflow.in/r/ followed by its token. This is the named independent source. Its provider-hosted record and the laboratory's own attestation are trusted for sample collection and result provenance. The Guardian cannot independently observe the blood draw; that limitation remains.

## Deliverables
Submit:
- `report.pdf`: the laboratory-issued final report showing collection and issue date/time with timezone, laboratory identity, report identifier, test method, hemoglobin, hematocrit, units, and any flags.
- `verification.txt`: the exact HealthFlow original-report URL and report identifier. The page reached at the URL must show the canonical report with the same values and timestamps as the PDF.
- `data.csv`: one row containing de-identified specimen ID, collection timestamp, result timestamp, hemoglobin, hematocrit, units, and report identifier.

Do not submit an identifiable report or any access credentials. If the provider-hosted original exposes identifying information, this route cannot be used for this bounty. A separate self-authored consent statement does not replace the laboratory attestation in the original.

## Acceptance Criteria
1. The provider-hosted original is readable without a login, is on the named HealthFlow origin, and matches the submitted report and CSV for laboratory, report ID, times, values, and units. A QR graphic, self-hosted copy, or PDF alone is insufficient.
2. The report records an actual human capillary-blood collection after bounty creation and a finalized laboratory measurement before the deadline. It names the measuring method and has both required analytes or explicitly states a failed measurement with the laboratory reason.
3. The same provider-hosted original identifies the measured specimen by a de-identified ID, records that the participant is an adult, and attests consent for this de-identified research use. That ID matches the PDF and CSV. Neither the submitted bytes nor the verification page exposes the participant's direct identifiers.
4. The CSV faithfully transcribes the original, with no fabricated, altered, or inferred result. A documented failed measurement is acceptable as an inconclusive physical result if the lab's original records the attempt and quality failure.

## How is the winner selected?
Only submissions passing every criterion qualify. Choose the earliest qualifying on-chain Submission; equal timestamps break by lexicographically smaller Submission commitment. If none qualifies, the outcome is `no_valid_submission`.

## Out of scope
No medical interpretation, diagnosis, treatment recommendation, or public disclosure of personal health information. A self-authored consent note alone does not authenticate a laboratory result or establish specimen linkage.
