Committed challenge

Challenge details & success criteria

The approved challenge, byte for byte as committed at funding. Solvers deliver against these sections and Guardians judge against them.

Summary

Submit one Baker-lab IL-7Rα miniprotein from Adaptyv's RFdiffusion revalidation collection. Guardians score published BLI kd. They do not run BLI.

Challenge details

Adaptyv retested RFdiffusion-designed IL-7Rα miniproteins (Cao et al. / Baker lab designs) with a standardized BLI affinity workflow and published sequences plus kinetic fields on Proteinbase collection rfdiffusion-re-validation. This is a wet-lab methods revalidation, not the EGFR or TREM2 community contests. Forty-two proteins are in the hashed snapshot; 15 have experimental kd. The author field is empty on these rows.

This bounty purchases one competitive published miniprotein from that retest. It does not purchase a new wet-lab campaign.

Definitions And Scope

A candidate is the amino acid string in binder.fasta. A match is the unique row with that sequence. Success establishes a published expressed IL-7Rα binder with a usable experimental kd. It does not establish a new physical sample or that the Solver performed the Baker-lab design protocol.

Required Outputs And Format

FileRequiredFormatMax sizePurpose

binder.fasta: one > header, then amino acids. Ignore the header. Strip ASCII whitespace. Nonempty. Only ACDEFGHIKLMNPQRSTVWY.

methods.md must contain the matched row's name and designMethod as case-sensitive contiguous substrings. Do not require author; it is empty in this snapshot. It must contain this exact sentence, including the period:

No new laboratory BLI was performed for this Submission.

Package rules:

  • archive format: none; one flat directory;
  • only binder.fasta and methods.md.

Access And Known Limitations

Guardians fetch that URL themselves and check SHA-256 of the raw bytes, including a UTF-8 BOM if present, with no decode before hashing. Parse with UTF-8-SIG. evaluations is JSON and includes bli_kinetic_curves. Do not fetch curve URLs. Missing access or a hash mismatch blocks judgment. There is no Proteinbase signature, notarization, or signed manifest for this snapshot. Guardians cannot independently prove Proteinbase authored the bytes. This bounty purchases historical analysis of the exact bytes whose SHA-256 is listed above.

Acceptance Criteria

Pass/Fail Checks

  1. Exactly two files, binder.fasta and methods.md.
  2. Size limits 20,480 and 102,400 bytes.
  3. FASTA alphabet rule.
  4. Exactly one matching sequence row.
  5. That row's designMethod equals the case-sensitive exact string rfdiffusion. Do not lowercase. RFdiffusion is not that value.
  6. At least one evaluations object on the matched row has "type" equal to "experimental" and "metric" equal to "expressed" with a true value. Treat JSON true, boolean true, and the strings true and True as true.
  7. At least one evaluations object on the same row has "type" equal to "experimental", "metric" equal to "binding", and a true value using the same true test. expressed, binding, and kd need not be the same object.
  8. At least one qualifying experimental kd as defined in Scoring. A non-qualifying kd object does not satisfy this check.
  9. methods.md contains name, designMethod, and the BLI disclosure sentence.

Scoring And Calculations

Walk the matched row's evaluations JSON array from the first element to the last. A qualifying kd is an object whose "type" equals "experimental", "metric" equals "kd", "target" equals "il7r", "unit" equals "M", and "valueType" equals "numeric", all as case-sensitive exact strings, and whose value parses with Python 3 float() as a finite number strictly greater than 0.0 and at most 1.0. Units are molar. Do not convert nM or other units. The snapshot has no failed-control field; do not invent one. All qualifying kd objects on that one hashed row are treated as comparable BLI measurements because they share this snapshot, target il7r, and unit M. Collect them in encounter order. Do not sort. Score is:

math.exp(sum(math.log(kd_i) for kd_i in kds) / len(kds))

in IEEE-754 binary64 using Python 3 math.log and math.exp on that list, left to right. Do not round except as those binary64 operations. If the qualifying set is empty, or math.exp or math.log raises OverflowError or ValueError, the Submission is invalid. Lower is better. Do not rank by esmfold_plddt or TM-score fields. Binary64-equal scores are ties and use the winner rule below.

Missing, Invalid, And Conflicting Results

  • Empty author is expected and is not a failure.
  • No experimental kd: invalid.
  • Unavailable fetch is an operational blocker.

Evidence And Provenance

The Poster selects the Proteinbase collection rfdiffusion-re-validation at the listed URL as the source of this historical BLI table. File identity is the SHA-256 on this page. Guardians fetch the bytes and check the hash. That verifies the selected snapshot, not a new assay and not Proteinbase authorship beyond those bytes. Link a candidate by exact sequence. There is no separate producer authentication commitment.

How is the winner selected?
  • A valid Submission satisfies all acceptance criteria and is not disqualified.
  • Lowest geometric-mean kd wins. Binary64 ties go to the lowercase Solver address that sorts first.
  • If no Submission is valid, the outcome is no_valid_submission.
Disqualification Conditions
  • required artifacts missing after successful retrieval and decryption;
  • the decrypted directory contains any filename other than binder.fasta and methods.md.

UTF-8 decode failure, FASTA parse failure, or Markdown that cannot be read as UTF-8 text fails the corresponding Pass/Fail check. There is no separate “corrupt artifact” disqualification.

Out Of Scope

Guardians must not rank by esmfold_plddt or TM-score fields. methods.md may mention BLI, RFdiffusion, or computational scores; those mentions do not disqualify and do not change the score. Non-rfdiffusion rows fail Pass/Fail Check 5. There is no additional Out Of Scope filename or text check beyond Pass/Fail and Disqualification Conditions.

Allowed Resources And Reuse

Published retest designs may be submitted. Disclose name and designMethod.

Guardian Verdict Instructions

Judge only submitted artifacts, this page, and the listed CSV. Do not run BLI.

Evaluation Procedure And Limits

  1. Fetch il7ra_revalidation.csv and check SHA-256.
  2. Open binder.fasta and methods.md.
  3. Apply Pass/Fail Checks.
  4. Geometric-mean experimental kd.
  5. Apply the winner rule.

One pass over 42 rows is enough.
