From 0f2a2ae80458a8559097638a947b5edad905b5a9 Mon Sep 17 00:00:00 2001 From: "palantir-valiot[bot]" <279094399+palantir-valiot[bot]@users.noreply.github.com> Date: Sat, 13 Jun 2026 22:13:34 +0000 Subject: [PATCH] Fix Ecto.ConstraintError on audit_logs_pkey during *_and_log Declare unique_constraint(:id, name: "_pkey") in changelog_changeset/1. Duplicate log attempts (retries, concurrent Multi steps, etc.) now return {:error, changeset} instead of raising. TDD: added regression tests under "audit log pkey unique constraint handling". Bumped to 1.0.4, updated CHANGELOG.
