Four commands. Two terminals. No login. No wallet. No trust in Protean Labs required.

1. Read the record from chain

cast call 0xE3c261F3C05D4c4710003cd6066EfD95094cf5f0 \
  "getRecord(bytes32)" \

  --rpc-url https://mainnet.base.org

2. Inspect via the indexer JSON API

curl -s https://www.protean.sh/ledger/api/v1/records/0xbfff6bd2925e1b40216eb427af5458b90586afe7ac4230b5a11b6b77eb577e45 | jq

3. Reproduce the canonical state digest from genesis

curl -sL https://raw.githubusercontent.com/proteanlabs1/ledger-mirror/main/scripts/index_ledger_from_genesis.py -o index.py
python3 index.py --rpc https://mainnet.base.org \

python3 index.py --digest-only --db protean.db
# Compare against https://www.protean.sh/ledger/api/v1/indexer/digest

4. Confirm published indexer digest

curl -s https://www.protean.sh/ledger/api/v1/indexer/digest | jq '.digest, .record_count, .last_block'

Verification

What we can attest to from indexer state. Replay-artifact + content-digest verification you run yourself — see the verify page for copy-pasteable shell snippets and the public mirror for the canonical reproducibility script.

  1. 01.Record exists on chain (read via indexer)Pass
  2. 02.Indexer captured RecordContentEmitted (content rendered above)Pass
  3. 03.Replay pointer is an external scheme — reader verifies via the cited URL/CID/txPass
  4. 04.Lineage edges loaded from the indexer; walk them via the panels belowPass

All 4 checks passed. The chain says what it says.

Summary

Public thesis/export asset thesis_2e56530bb9511cdd. We propose that Candidates with cyclization, disulfide, or high-proline constraint handles may need a separate structural validation path from unconstrained linear peptides. Our synthesis is drawn from 5 trusted-tier supporting and 5 contradicting reference(s) relevant to protease_resistance, structural_motif, with aggregate evidence strength 0.35 (max 1.0) and uncertainty 0.34. We frame the resulting claim as a candidate hypothesis whose acceptance depends on the experimental program in §10; the per-section confidence header and §9 Limitations bound the scope of the synthesis. Boundary: public research artifact with explicit uncertainty, not biological validation.
