openwright-postgres 0.4.0

PostgreSQL ledger backend for OpenWright — durable, multi-writer evidence.

openwright-postgres

A durable, multi-writer PostgreSQL ledger backend for OpenWright — the production answer to the file/sqlite single-writer limit.

pip install openwright openwright-postgres
openwright collector --ledger-backend "postgresql://user:pw@host:5432/evidence"

Or in code:

from openwright.connectors import resolve_backend
from openwright.ledger import Ledger
ledger = Ledger(resolve_backend("openwright.ledger_backends", "postgresql://…"))

It uses core's append-only SqlLedgerBackend (DB-assigned IDENTITY column — no MAX(idx)+1 race, O(1)+indexed positional reads), so concurrent writers commit gap-free, ordered, and verifiable. Crypto stays in core; this package only wires storage. Produces evidence that controls were exercised — not a legal compliance certification.
