Veritas Kanban 6.0.1 is the first supported stable v6 release.

It adds first-class Buzz integration and gives Grok Build, OpenAI Codex, Claude Code, and GitHub Copilot CLI the same evidence-backed task, worktree, tool, approval, credential, event, and completion boundaries.

**Release status:** Veritas Kanban 6.0.0 remains available as a quarantined prerelease. Install 6.0.1 or newer.

## Highlights

### One control plane for agent harnesses

- Buzz Agent, Grok Build, and GitHub Copilot CLI run through the shared ACP v1 adapter.
- OpenAI Codex supports CLI, SDK, and the richer app-server JSON-RPC lifecycle.
- Claude Code runs through a supervised bare-mode stream.
- Hermes and OpenClaw retain their supported one-shot and gateway transports.
- Settings, API diagnostics, telemetry, dispatch, and `vk doctor --json` now report the same support tier and redacted readiness evidence.

Equal footing does not mean pretending every provider has the same features. Veritas probes the installed version and capabilities, then persists that evidence.

Unsupported resume, tool, approval, sandbox, or completion behavior is blocked before an attempt starts.

### First-class Buzz support

- Connect a pinned Buzz community channel to Squad Chat.
- Import signed public persona and team definitions as disabled profiles.
- Run `buzz-agent` through ACP with exact version and capability checks.
- Expose only the selected run-scoped Veritas tools.
- Trigger allowlisted Veritas workflows from Buzz root messages with durable replay protection.

Buzz relay delivery remains a communication path. Veritas remains the authority for tasks, attempts, tools, approvals, and completion.

### Safer, recoverable runs

- Every run records its task envelope, launch policy, worktree baseline, provider runtime evidence, causal events, approvals, tool catalog, and completion evidence.
- Restart and reconnect logic verifies ownership before resuming work, avoiding silent duplicate runs.
- Provider build or capability drift invalidates old certification.
- Credential-bearing tools use one-shot, exact-action leases instead of exposing raw secrets to provider configuration or logs.
- The desktop updater rejects older release metadata instead of offering a downgrade.

## Stabilization fixes in 6.0.1

- Chat is a reversible desktop panel with visible close, Escape, browser Back, startup-state recovery, and native layout reset ([#945](https://github.com/BradGroux/veritas-kanban/issues/945)).
- Task drawers, shared overlays, Archive cards, scoring pages, and the template editor have reachable scrolling and resizing ([#935](https://github.com/BradGroux/veritas-kanban/issues/935), [#938](https://github.com/BradGroux/veritas-kanban/issues/938), [#939](https://github.com/BradGroux/veritas-kanban/issues/939), [#941](https://github.com/BradGroux/veritas-kanban/issues/941)).
- Workflow actions handle omitted collections and recoverable load failures instead of crashing task detail ([#936](https://github.com/BradGroux/veritas-kanban/issues/936)).
- Full-page views, task detail, and nested Workflow overlays preserve their actual route origin, browser history, keyboard Back behavior, and scroll position ([#937](https://github.com/BradGroux/veritas-kanban/issues/937)).
- New scoring profiles open as visible, validated drafts ([#943](https://github.com/BradGroux/veritas-kanban/issues/943)).
- Operations Digest reconciles board inventory with windowed events and exposes source IDs and metadata-quality findings ([#944](https://github.com/BradGroux/veritas-kanban/issues/944)).
- The packaged desktop consistently reports its real application version ([#986](https://github.com/BradGroux/veritas-kanban/issues/986)).

## Install or upgrade

### Homebrew

```bash
brew update
brew upgrade --cask bradgroux/tap/veritas-kanban
```

For a first install:

```bash
brew install --cask bradgroux/tap/veritas-kanban
```

### Direct download

Download the signed and notarized macOS arm64 DMG or ZIP from the [v6.0.1 release](https://github.com/BradGroux/veritas-kanban/releases/tag/v6.0.1).

Back up the current workspace before upgrading. Keep the v5.2.5 backup until the v6 runtime is accepted.

If rollback requires an older schema, restore the pre-upgrade backup instead of opening newer data with an incompatible binary.

Follow the [v6 upgrade and administration guide](https://github.com/BradGroux/veritas-kanban/blob/v6.0.1/docs/V6-UPGRADE-INSTALL-ADMIN-GUIDE.md) for migration, remote access, validation, and rollback.

## Important behavior changes

- Provider-less or adapter/profile-mismatched records no longer fall through to OpenClaw.
- Unknown or changed provider builds lose certification until current probes and deterministic fixtures pass.
- Claude Code no longer launches with `--dangerously-skip-permissions`.
- Credential-bound MCP servers are not copied into provider-native configuration. They are available only through the mediated run bridge.
- Conversation controls appear only when the selected provider proves it supports them.
- The public REST API remains mounted at `v1`; the v6 product version does not rename API routes.

## Known limitations

- Buzz Agent sessions are in-memory and do not support session load/resume. Buzz files, reactions, forums, DMs, and destructive edit/delete projection are not bridged.
- GitHub Copilot CLI ACP is public preview.
- Grok Build's stable artifact self-reports alpha and cannot be fully traced to the current public source tree.
- Claude Code's complete CLI implementation is not public, so certification is bound to exact release behavior and checked-in fixtures.
- Linux and Windows desktop artifacts remain unsigned previews. Signed and notarized macOS arm64 is the supported desktop distribution.
- Deterministic compatibility does not prove provider authentication, subscription availability, quota, or live inference.
