Schema Governance¶

The package owns repository-level helpers that keep API schemas and tracked schema artifacts synchronized with the code that claims to implement them.

Schema drift is one of the easiest ways to lose user trust quietly. This page should make it obvious where the repository checks that risk and why that work belongs in maintainer tooling.

These maintainer pages should read like explicit operational memory for repository-health work. They are strongest when they expose automation intent, package impact, and repository policy without pretending that CI logs are documentation.

Current Surfaces¶

api/openapi_drift.py
tests such as tests/test_openapi_drift.py
root apis/ directories that store reviewed schema artifacts

Concrete Anchors¶

packages/bijux-canon-dev/src/bijux_canon_dev for maintainer helpers
packages/bijux-canon-dev/tests for executable maintenance proof
apis/ and root workflows for repository-level integration points

Use This Page When¶

you are changing repository automation, validation, or release support
you need maintainer-only context that should not live in product package docs
you are reviewing CI, schema drift, or supply-chain behavior

Decision Rule¶

Use Schema Governance to decide whether a change belongs to maintainer automation or to a product package contract. If the change would affect end-user behavior directly, this page should push the review back toward the owning product package instead of letting maintainer scope sprawl.

What This Page Answers¶

which repository maintenance concern this page explains
which maintainer modules or tests support that concern
what a reviewer should confirm before changing repository automation

Reviewer Lens¶

compare the described maintainer behavior with the actual helper modules and tests
check that maintainer-only guidance has not leaked into product-facing pages
confirm that repository automation still names its package impact explicitly

Next Checks¶

move to product package docs if the question is user-facing behavior rather than repository health
open the relevant helper module or test after using this page to orient yourself
return to repository handbook pages when the maintainer issue turns out to be root policy instead

Honesty Boundary¶

This section can describe maintainer automation and repository health work, but it should never imply that maintainer tooling is part of the end-user product surface. It also should not pretend that hidden scripts count as documentation just because CI happens to run them.

Purpose¶

This page explains why schema drift detection belongs in the maintainer package.

Stability¶

Keep it aligned with the actual drift tooling and tracked schema files.
