Compatibility is verified before release.
Every extension will publish an explicit OpenCart, PHP and dependency matrix after standalone validation. No inferred version ranges and no silent dependencies.
Current validation status.
Version cells remain intentionally unresolved until clean-install testing is complete.
Four gates before a compatibility claim.
Clean environment
Install on a clean OpenCart environment without the production store's theme or unrelated extensions.
Version matrix
Exercise the extension against explicitly selected OpenCart and PHP combinations.
Lifecycle checks
Test install, configuration, upgrade and uninstall behavior, including generated files and database changes.
Documentation match
Verify that published requirements and instructions match the tested build.
Compatibility questions.
Why not publish likely versions now?
Because syntax compatibility is not the same as operational compatibility. Fencair will publish ranges after clean-install tests.
What if another extension is required?
Any required dependency will be listed explicitly. The goal is to remove private or store-specific dependencies before release.
What if my setup is not listed?
An unlisted combination should be treated as unverified, not assumed compatible.
