# NoahAI v3.9.1.15 Strategy Studio and Verified Strategy Hub boundary

Date: 2026-08-29
Status: current stable public Windows release; external-environment feedback validation continues

## Product name and compatibility

- `NoahAI Strategy Studio` is the official product name of the former AI Custom workspace.
- The Korean client tab is `전략 스튜디오`.
- Internal API names, storage identifiers, and the `.noahstrategy` package extension remain compatible.
- `Strategy OS` describes the long-term product vision; it is not a second client tab.

## Current Strategy Studio scope

- Level 1: plain-language source, scope, and risk review.
- Level 2: entry, exit, risk budget, and applied-value inspection.
- Level 3: source-to-rule trace, full constrained IR, versioning, approval, historical replay, and PAPER forward validation.
- Level 4: bounded expert operating policies. Approval, daily-loss stop, position/concentration limits, exchange order rules, TP/SL protection, duplicate-order prevention, reconciliation, and emergency stop cannot be disabled.

Saving a strategy is not execution. A version must be reviewed, approved, checked, and validated in PAPER before it can become an execution candidate. Past or simulated results never guarantee future returns.

## Free Verified Strategy Hub

The free public beta is operated at `https://daltrading.net/strategies`.

1. A member exports a `.noahstrategy` package from the client.
2. The member signs in to daltrading and submits the package with source, rights, market, risk, and public-description declarations.
3. The submission remains private during operator review.
4. Only approved packages become publicly downloadable with a validation passport.
5. A downloaded package imports into NoahAI as an inactive review version and does not bypass approval, checks, PAPER validation, or guardrails.
6. A creator publication-stop request immediately hides the strategy and blocks new downloads while preserving the package and audit history. An operator then confirms the stop or rejects and republishes it.

Performance-based fees, paid subscriptions, settlement, refunds, disputes, tax handling, blockchain, NFTs, and tokenization are not part of this free-beta scope.

## Verification and release boundary

The v3.9.1.15 source passed the NoahAI Python regression suite (`1,898 passed, 8 skipped`) and Web UI production build. The daltrading strategy-hub source passed its full suite (`80 passed, 3 subtests passed`). NoahAI Labs and public information pages also passed production builds.

The official GitHub v3.9.1.15 release was published on 2026-08-29 with a matching installer, embedded engine sidecar, blockmap, `latest.yml`, and `release-manifest.json`. The public manifest identifies the stable channel and `publish_ready=true`; the website therefore describes v3.9.1.15 as the current public Windows release.

Distribution does not prove defect-free operation on every exchange, broker, account, network, or Windows environment. Upgrade, restart, settings preservation, Strategy Studio/PAPER, multi-exchange, broker, long-run, and rollback feedback remain evidence that must be monitored and improved without being presented as guaranteed trading performance.
