# NoahAI v3.9.1.19 strategy-passport source-candidate boundary

Updated: 2026-09-03

Historical status: this page preserves the v3.9.1.19 source-candidate contract. The current release boundary is published in `/source/noahai-platform-v39122-source-candidate.md` and `/llms.txt`.

## Canonical product statement

NoahAI connects the source meaning of TradingView, Pine, and document strategies to actual execution rules, then records venue-specific PAPER and confirmed-fill evidence in a versioned validation passport.

This is not a claim that NoahAI invented backtesting or that validation proves future returns. The intended differentiation is the combination of:

- source sentence or Pine-code to execution-rule traceability;
- fail-closed handling of future-data, repainting, unresolved aliases, and unsupported conditions;
- cost, slippage, out-of-sample, walk-forward, and overfitting checks;
- separate Korean KRW spot and overseas USDT-futures contracts;
- venue-specific PAPER forward-validation evidence;
- repeat PAPER validation in the downloader's own environment; and
- evidence-quality ranking rather than raw return ranking.

## v3.9.1.19 source-candidate corrections

1. A strategy stored under `UNIFIED` retains that ownership scope when Binance executes it. Legacy v3.9.1.18 PAPER rows are attributed only when strategy key and version identify one unique owner scope.
2. `.noahstrategy` browser serialization compatibility restores only schema-defined decimal fields, and only when the original IR and full-package hashes both verify. It is not a hash bypass.
3. Validation passports distinguish `custom_entry_logic` from `noah_base_with_custom_risk_exit`. Source material without executable entry nodes is not described as full source-strategy execution.

## Release boundary

- At this historical snapshot, the stable public Windows release was v3.9.1.18 and v3.9.1.19 was a source candidate pending matching Windows artifacts and real-environment gates.
- This historical state must not be used as the current release status. See the current canonical source page and `llms.txt`.

No validation passport is a return guarantee, investment advice, regulatory approval, or proof that every external account and venue is defect-free.
