ledger.registry — v1.1

Goal

Provide a single source of truth for active ledgers and integrity status.
If missing, auto-generate

/ledger/profile.json

(energy-aware preferences) based on

profile.schema.json

+

profile.defaults.json

.

Inputs

• none (or

  verify=true

  to force SHA-256 recompute)

Outputs

• Returns manifest summary:
  • module → path
  • schema version
  • metadata.version
  • metadata.checksum (valid/invalid)
• Auto-generates

  profile.json

  if absent, ensuring downstream Skills can use energy preferences.

Mechanism

1. Load

   /ledger/manifest.json

   or scan

   /ledger/

   for

   .json

   files.
2. Check for presence of module

   "profile"

   :
   • If absent → call

     ensure_profile(ledger_dir="/ledger")

     .
   • Reload ledger list to include the newly created

     profile.json

     .
3. For each ledger, recompute checksum; compare with

   metadata.checksum

   per Structure DNA integrity rules.
4. Write updated checksums and ledger list back to

   /ledger/manifest.json

   .
5. Return runtime registry map.

Pseudocode

def run_registry(ledger_dir="/ledger"):
    ledgers = scan_ledgers(ledger_dir)

    # ✅ NEW STEP: ensure profile.json exists
    if not any(L["module"] == "profile" for L in ledgers):
        ensure_profile(ledger_dir)  # uses profile.schema.json + profile.defaults.json
        ledgers = scan_ledgers(ledger_dir)  # re-scan to include it

    manifest = build_manifest(ledgers)
    manifest["metadata"]["last_sync"] = now_iso()
    manifest["metadata"]["checksum"] = recompute_checksum(manifest)
    save_json(f"{ledger_dir}/manifest.json", manifest)
    return manifest
