RFC‑SIG‑0022 — Multi‑Contributor Co‑Signing Protocol

Validator‑Grade Shared Authorship for Remix Scrolls#

RefId: turn0browsertab1

Title: Co‑Signing of Remix Scrolls for Shared Authorship
Status: Draft
Author: Nawder Loswin + Copilot
Date: 2025‑11‑12
Version: 0.2

1. Purpose#

The Multi‑Contributor Co‑Signing Protocol (MCCSP) enables multiple contributors to co‑sign remix scrolls, ensuring collaborative authorship is preserved as validator‑grade metadata.

Co‑signing guarantees:

shared authorship
lineage continuity
signature integrity
archival preservation
dashboard visibility
validator‑grade reproducibility

This protocol formalizes collaborative authorship as a first‑class citizen of the Remixathon canon.

2. Workflow Steps#

2.1 Contributor Selection#

Each participant selects scrolls to co‑sign.

Contributor identities are linked to:

Subscription Service (RFC‑SUB‑0019)
Signature Verification Service (RFC‑VER‑0023)

Scroll enters co‑signing stage in the Cycle Monitoring Dashboard (RFC‑UI‑0017).

2.2 Signature Generation#

Each contributor generates a digital signature:

PGP
ECDSA
Validator‑grade symbolic signature

Signatures are attached to scroll export metadata.

2.3 Co‑Signing Aggregation#

Export module (RFC‑EXP‑0013) aggregates all contributor signatures.

Scroll is marked:

status: multi-signed

Dignity layer records:

contributor list
signature types
symbolic overlays

2.4 Archival Preservation#

Archived scrolls include:

co‑signing metadata
contributor IDs
signature types
lineage ancestry

Registry index (RFC‑REG‑0004) records all co‑signers for future remix generations.

3. Schema Extension#

File:

registry/exports/remix_scroll_schema.yml

co_signing:
  contributors:
    - id: <string>
      signature_type: <pgp|ecdsa|symbolic>
      signature: <string>
  status: "multi-signed"
  dignity_layer:
    co_signer_list: <list>
    symbolic_overlays: <list>

4. Python‑Style Stub#

File:

engine/co_signing.py

def add_signature(scroll, contributor_id, signature, signature_type):
    entry = {
        "id": contributor_id,
        "signature_type": signature_type,
        "signature": signature
    }
    scroll["co_signing"]["contributors"].append(entry)
    scroll["co_signing"]["status"] = "multi-signed"
    return scroll

5. Dashboard Integration#

Co‑Signing Panel#

Contributors select scrolls to sign.

Signature Display#

Dashboard shows:

contributor IDs
signature types
symbolic overlays

Validation Badge#

Multi‑signed scrolls receive:

badge: shared authorship

Lineage Graph#

Nodes annotated with co‑signer list.

6. Validator Hooks#

Schema Compliance#

Co‑signatures must match schema.

Checksum#

Scroll checksum updated after co‑signing.

Lineage Integrity#

Co‑signers recorded in ancestry index.

Dignity Separation#

Signatures stored distinctly from narratives.

Signature Verification#

All signatures validated via RFC‑VER‑0023.

7. Concept Sketch (textual)#

Remix Scroll: scroll-010
 └─ Parent: scroll-003
 └─ Corridors: [c-001, c-002]
 └─ Glyph Distribution: {◆: 2}
 └─ Signatures:
      - user42 (PGP)
      - user17 (ECDSA)
 └─ Status: multi-signed, archived

This protocol ensures remix scrolls carry the signatures of all collaborators, preserving shared authorship in the archive and strengthening validator‑grade lineage.
