archestra-ai/openappa v0.35.0 is a new release of the deterministic guardrail store for agents. According to the v0.35.0 release notes on GitHub, it ships typed classification of denial results and adds a host namespace alias table to policies. Both changes were presented as backward-compatible. The storage schema also moved up to version 9. The source for the version and the changes is that release record.
The project describes itself as deterministic guardrails that do not break agents. This edition adds both the ability to classify denial results by type and a table for handling host namespace aliases in policies. So the core of this update is two changes: denial classification and host alias handling in policies. The storage schema change is included in the same release, and existing trajectories are preserved. The public repository has 1581 stars.
However, a version9 schema database is rejected by a correct older runtime that cannot read it. Therefore, rolling back by using a version 9 schema database on an older runtime is not possible. This limit is the compatibility boundary stated in the release description. FACTS did not provide details on denial type subcategories, the concrete behavior of the alias table, performance comparisons, or an upgrade procedure. So on this material alone, neither the scope of the two features nor their performance impact can be judged.
