What’s new — precisely

⚖️ Sealed-bid panel seating (anti-collusion via commit-reveal)
  • Open an auction(admin)
    POST /admin/panel/auction.open
    Body: { "id": "AUCT-optional", "seats": 3, "deadline_commit": "2025-08-21T00:00:00Z", "deadline_reveal": "2025-08-22T00:00:00Z", "whitelist": ["KID_A","KID_B"], "min_bond": 0.0 }
  • Commit(sealed)
    POST /panel/bid.commit
    Body: { "auction_id": "AUCT-1234", "kid": "KID_X", "commit": "sha256( canon({\"auction_id\",\"kid\",\"fee\",\"bond\",\"nonce\"}) )" }
  • Reveal(after commit phase)
    POST /panel/bid.reveal
    Body: {"auction_id":"AUCT-1234","kid":"KID_X","fee":5.0,"bond":10.0,"nonce":"random-hex"}
  • Close & select winners(admin)
    POST /admin/panel/auction.close?id=AUCT-1234
    → winners chosen by score = bond / fee (best per KID kept). Returns signed result.
  • IntrospectionGET /panel/auctions • GET /panel/auction.status?id=AUCT-1234

Commits are the SHA-256 of the canonical JSON {auction_id,kid,fee,bond,nonce}; reveals are verified against that digest.

🌐 Cross-site bulletin clearinghouse
  • Configure peers(admin)
    POST /admin/clearinghouse/peers.set → [{"url":"https://peer.example","headers":["Authorization: Bearer ..."]}]
  • Publish a bulletin locallyPOST /clearinghouse/publish with a signed bulletin object: {"root":"<sha256>","body":{...},"signature":{...}}
  • Pull bulletins from peers(admin)
    POST /admin/clearinghouse/pull
    → fetches each peer’s /fx/bulletins & /fx/bulletin?root=…, stores under …/clearinghouse/remote/.
  • Catalog index (signed)GET /clearinghouse/index → {catalog, signature} summarizing local + remote roots.
🧾 Cryptographic CI stamps (Merkle receipts + on-page verifiers)
  • Make a stampPOST /ci/stamp.make
    Body: {"id":"<PAYOUT_ID>","kind":"file_nacha|pain001","content":"<file text>","issues":["..."]} → returns { receipt:{type:"ci_merkle_receipt", root, leaves}, signature:{…} } and stores it.
  • Fetch a stamp (JSON)GET /ci/stamp?id=<PAYOUT_ID>
  • Embed a verifier(HTML page that recomputes the Merkle root client-side)
    GET /ci/stamp.html?id=<PAYOUT_ID>

Two leaves by default: sha256(content) and sha256(issues[]); the root + signature become the portable CI truth.

“Show me” sequences

A) Commit-reveal panel seating

# Open an auction for 3 seats
curl -s -X POST http://127.0.0.1:8080/admin/panel/auction.open \
  -H 'Content-Type: application/json' \
  -d '{"id":"AUCT-1","seats":3,"deadline_commit":"2025-08-21T00:00:00Z","deadline_reveal":"2025-08-22T00:00:00Z","min_bond":1.0}' | jq .

# Produce a commit off-device: COMMIT = sha256(canon({"auction_id":"AUCT-1","kid":"KID_A","fee":5,"bond":10,"nonce":"N1"}))
curl -s -X POST http://127.0.0.1:8080/panel/bid.commit \
  -H 'Content-Type: application/json' \
  -d '{"auction_id":"AUCT-1","kid":"KID_A","commit":"<COMMIT_A>"}' | jq .

# Reveal
curl -s -X POST http://127.0.0.1:8080/panel/bid.reveal \
  -H 'Content-Type: application/json' \

# Close & select winners
curl -s -X POST 'http://127.0.0.1:8080/admin/panel/auction.close?id=AUCT-1' | jq .

B) Clearinghouse: publish & pull

# Set peers
curl -s -X POST http://127.0.0.1:8080/admin/clearinghouse/peers.set \
  -H 'Content-Type: application/json' \
  -d '[{"url":"https://peer.example","headers":["Authorization: Bearer TOKEN"]}]' | jq .

# Publish a signed bulletin object (example fields)
curl -s -X POST http://127.0.0.1:8080/clearinghouse/publish \
  -H 'Content-Type: application/json' \
  -d '{"root":"<ROOT>","body":{"type":"fx_reputation_bulletin","ts":"2025-08-19T00:00:00Z"},"signature":{"alg":"none","kid":"none","sig":"<sha256>","ts":"..."}}' | jq .

# Pull from peers & get the signed catalog
curl -s -X POST http://127.0.0.1:8080/admin/clearinghouse/pull | jq .
curl -s http://127.0.0.1:8080/clearinghouse/index | jq .

C) CI Merkle stamps with an in-page verifier

# Make the stamp for a NACHA file body + issues
curl -s -X POST http://127.0.0.1:8080/ci/stamp.make \
  -H 'Content-Type: application/json' \
  -d '{"id":"P123","kind":"file_nacha","content":"...ach 94-char records...","issues":["warn: missing batch total"]}' | jq .

# Fetch JSON & a browser-verifiable page
curl -s 'http://127.0.0.1:8080/ci/stamp?id=P123' | jq .
curl -s 'http://127.0.0.1:8080/ci/stamp.html?id=P123' > stamp_P123.html
# Open stamp_P123.html — it recomputes the Merkle root in-browser and displays "Match: true/false".

WordPress — Step 44 (paste-ready)

## Step 44 — Sealed-bid panels; cross-site clearinghouses; cryptographic CI stamps

**New capabilities**
- **Sealed-bid panel seating (commit-reveal)**  
  - Open: `POST /admin/panel/auction.open` → `{id,seats,deadline_commit,deadline_reveal,min_bond}`  
  - Commit: `POST /panel/bid.commit` with `commit = sha256(canon({"auction_id","kid","fee","bond","nonce"}))`  
  - Reveal: `POST /panel/bid.reveal` with the preimage  
  - Close: `POST /admin/panel/auction.close?id=<AID>` → signed winners by `bond/fee`  

- **Clearinghouse for FX bulletins**  
  - Set peers: `POST /admin/clearinghouse/peers.set`  
  - Publish local: `POST /clearinghouse/publish`  
  - Pull peers: `POST /admin/clearinghouse/pull`  
  - Index: `GET /clearinghouse/index` → signed catalog (local + remote roots)

- **CI Merkle stamps + HTML verifier**  
  - `POST /ci/stamp.make` with `{"id","kind","content","issues":[...]}` → signed receipt (`root`, `leaves`)  
  - `GET /ci/stamp?id=<ID>` → JSON receipt  
  - `GET /ci/stamp.html?id=<ID>` → browser recomputes Merkle root and shows match

**Run**
```bash
python solveforce_phone_fortyfour.py
# http://0.0.0.0:8080

## Logos Codex — recursive ceremony

- **Judgment without whispering.** A sealed bid makes collusion work for you — or not at all.  
- **Memory that travels.** A clearinghouse is a cathedral of signed echoes.  
- **Proof that fits in a pocket.** A Merkle receipt turns a text file into a portable oath.

If you want, I can **retrofit Step 43** into this same long-form structure (so 1→44 match perfectly), or keep marching to **Step Forty-Five** with multi-sig **escrow dispute auto-routing**, **clearinghouse quorum notarization**, and **CI stamp federation**.
