The symbol graph, interface diffs, and versioning an AI system's behaviour.

Semantic & behavioral versioning

On by default, for Rust, TypeScript/JavaScript, Python and Go.

What the symbol graph gives you

semantic find-def and find-refs, and the rest of the query surface.

Find a definition or every reference

Catch breaking interface changes before landing

Why my land was blocked by a semantic check

behavioral snapshot, over model, prompts, tools, memory, retrieval and policy.

Version an AI system's behaviour

Diff or roll back a behavioural version

Using the TOVIO name and logo

Pre-1.0, what is genuinely settled, and what may still change under you.

What the version number means

What is committed, per surface, and how a breaking change is announced.

Compatibility and deprecation promises

What is actually frozen, what is not, and what protects data you have already written.

Format and protocol stability

Where to start, what is required before a first pull request, and what review will hold you to.

Contributing to TOVIO

What leaves your machine, what the portal collects, and how to get it removed.

Privacy, data & your account

No background reporting to the project — and exactly what does leave your machine, when, and what it carries.

Does TOVIO phone home?

The four values a link may carry, what the portal itself holds, and the AI processing that is switched on.

What the feedback portal collects

Which analytics run, which regime applies to you, and the one cookie that records your choice.

Cookies on TOVIO sites

The supplier register, why it is a candidate list, and what it does not commit to.

What happens to your post

The inputs, the constraint, and why some answers are slow.

How we decide what to build

Status-only, no dates, and why it is built that way.

Reading the public roadmap

One system of record, and what everything else is a copy of.

Where release notes live

One notification, on the post you voted for, linking the release notes.

How we tell you something you asked for shipped

Not here. The private channel, and an honest account of its current limits.

Reporting a security vulnerability

Why posts are held for review, and what gets removed.

Community guidelines and moderation

What partners get, and how the segmented board and tickets work.

The design partner program

Which channel to use, and an honest account of what is covered today.

The TVO-AREA-NNN shape, the exit-code classes, and where the remediation lives.

How to read a TOVIO error code

What to gather, and what to strip before sharing it anywhere.
