From da44e8ecbed4aa916fc286ccc343ec59f3f0879c Mon Sep 17 00:00:00 2001 From: Matt Ciaccio Date: Tue, 28 Apr 2026 02:22:04 +0200 Subject: [PATCH] feat(documenso): version-aware field placement + void abstractions Adds DOCUMENSO_API_VERSION env (default v1) plus per-port override. Introduces placeFields, placeDefaultSignatureFields, and voidDocument that hide v1 (per-field POST, pixel coords) vs v2 (bulk POST, percent + fieldMeta) differences. cancelDocument now voids in Documenso first and treats transient void failures as recoverable so the CRM stays the system of record. 16 unit specs cover dispatch, layout math, idempotent 404, and v1 pixel conversion.
