v0.99.5.2 — Schema Integrity, Automated Migrations, Expanded Test Coverage

Infrastructure and reliability release. Establishes automated migration deployment as a standard part of the CI/CD pipeline, expands end-to-end test coverage to eleven new test suites, and hardens the platform against accidental schema drift between environments.

Automated Migration Deployment​

Database schema migrations are now applied automatically as part of every deployment to staging and production. Previously, migrations required a separate manual step after code deployment — a gap that caused the 2026-05-18 schema drift incident where production was running code that expected schema changes that had not yet been applied.

The new workflow:

  • Runs migration deployment before the application starts handling requests on every environment push
  • Checks that production and staging are always in sync on every CI run, and fires a platform alert if drift is detected
  • Catches schema divergence at the CI level before code is merged, not after it is deployed

A pre-commit guard has also been added to the development workflow that prevents a schema change from being committed without a matching migration file, closing a class of developer-level drift errors at the source.

Expanded End-to-End Test Coverage​

Eleven new end-to-end Playwright test suites have been added, covering:

  • Wizard validation — extended coverage for product data wizard field validation and rejection behaviour
  • Document upload flows — full upload cycle including file type validation and error states
  • AI features — document extraction and compliance analysis flows, including quota-reached handling
  • Withdrawal flow — DPP withdrawal and re-publication lifecycle
  • Verifier round-trip — complete operator → verifier → approval cycle
  • Public DPP — full body rendering and JSON-LD output correctness for all battery categories
  • Audit log integrity — verifies that audit records are written correctly and the hash chain is unbroken after key platform events
  • Save and resume — concurrent wizard save-and-resume behaviour under parallel sessions
  • Slug and retired slug handling — GTIN resolution edge cases and retired slug redirect behaviour
  • Mobile public DPP — full DPP page rendering across common mobile viewports

These suites bring the total automated end-to-end coverage to 23 passing tests with 0 failures.

Operator Help Documentation​

Five operator help pages were updated with a factual correction: the DPP edit window after publishing is 14 days, not 30 days as previously documented.

Platform Notes​

This release also includes supplier-portal reliability improvements behind a feature flag that is active on staging only. These changes — including an improved supplier inbox, materials library, and certificates page with cross-operator identity awareness — will be promoted to production in a future release once the staging validation period is complete.
