Yes — that's chained tracks, live since 2026-07-16. The same sealed strategy is re-proven over a strictly longer data window as data accrues; each link is cryptographically bound to its parent (same strategy commitment, same locked gate, the old window a Merkle prefix of the new). Your backtest becomes a growing, verifiable track — one click in the app. The live chain: a 19,670-bar parent, committed and anchored in Bitcoin block 962,013 before the new data existed, extended to 19,671 bars on 2026-08-11 — 20 checks green across the chain walk (the 17 single-credential checks plus chain-continuity checks). Re-verify it yourself. An earlier v3-era chain (parent 800 bars → extension 1,096 bars) remains public as the first engineering proof of the mechanism. Boundary: chaining extends the proven computation window; it does not attest live execution or fills.
Every number above is on the record: every credential · verify one yourself · the vocabulary · all questions.
