TAHAI OS—SENTINEL is a Linux-based AI workstation OS for governed execution, local-first development, BYOK provider access, distributed agents, and visible operator control.

## Public summary
TAHAI OS—SENTINEL gives AI work a workstation-level home. The OS organizes the machine, the browser opens the right doors, Prefrontal Node provides local orchestration authority, and SENTINEL turns advanced coding and distributed-agent work into visible, governed execution. The public promise is a visible path from intent to proof: command, scope, execute, verify, recover, and improve.

## Release status
Initial public release is not yet available. Expected public release window: mid–late May 2026. The current site is a public product preview, not an installer, purchase flow, or production support channel.

## Product roles
- TAHAI OS—SENTINEL: workstation platform and paid flagship lane.
- Prefrontal Node: canonical local orchestration daemon and contract authority.
- SENTINEL: advanced coding and operator control plane.
- TAHAI Web Services Browser: standalone free browser and acquisition lane.

## Monetization model
- Free browser: awareness, onboarding, provider-console access, and ecosystem discovery.
- Paid OS: flagship workstation platform after the public release opens.
- SENTINEL: premium advanced control-plane differentiator.
- Team and Enterprise: policy, support, diagnostics, private channels, and organization-grade control.

## Adoption path
The intended path is clean: discover through the free browser and TAHAI brand surface, understand the operating system at os.tahai.net, operate advanced coding and agent work through SENTINEL, and scale into team or enterprise lanes when policy, diagnostics, and support matter.

## Boundary
os.tahai.net explains the operating system publicly and previews the coming release. The operating system release itself remains a separate platform build and distribution lane; the initial public release is expected mid–late May 2026.

## Governed execution
Governed execution means visible routes, scoped provider access, worker state, checkpoints, diagnostics, and recovery signals instead of hidden AI work scattered across disconnected tabs and scripts.

Trust rail summary: TAHAI OS—SENTINEL emphasizes visible, bounded, recoverable AI work through scoped credentials, explainable routes, observable workers, diagnostics, and clear ecosystem roles.

## Expected release shape
The first public release is expected to introduce the workstation-platform lane: branded OS experience, curated browser orientation, BYOK posture, local orchestration authority, and an operator-control path. The OS itself is not publicly available yet.

## Public website boundary
This is a static public website for os.tahai.net. It is not the OS build itself, not an installer endpoint, not a purchase flow, and not a production support channel yet.

## Public evaluation posture
Before the initial public release opens, TAHAI OS—SENTINEL is a public product preview for a Linux-based AI workstation OS. Evaluation focuses on local authority, BYOK provider access, visible execution, bounded work, diagnostics, recovery evidence, and clean separation between OS, SENTINEL, Prefrontal Node, and the browser. Do not imply that public download, purchase, or production support channels are live yet.
