Regenerates the test/fixtures/install_golden/ baseline driven by the
Sigra.Test.InstallFixture harness, then prints a structured delta report
grouped by top-level directory so the operator can review what changed
without eyeballing a 20+ file raw diff.
This automates the manual iex-driven runbook in
.planning/phases/24-repair-phase-16-17-organizations-generator-templates/24-01-repair-phase-16-17-org-templates-PLAN.md:953-1025
and the older runbook in
.planning/phases/11-generator-feature-system/11-01-SUMMARY.md.
Usage
MIX_ENV=test mix sigra.fixture.rebless_golden
MIX_ENV=test mix sigra.fixture.rebless_golden --check--check writes to a tmp dir and diffs against the committed fixture without
modifying test/fixtures/install_golden/. Exits 2 if drift is detected. This
mode is suitable for a CI drift-detector job.
The task does NOT stage, commit, or amend. After a normal (non-check) run,
review git diff test/fixtures/install_golden/ before committing.
