DCENT_OS beta20260709 release evidence
DCENT_OS decision guide
beta20260709: verify the exact board before any file
Two operator downloads are authorized by the current V7 binding: the S9 Xilinx SD trial for CRT0401/CRT0402 JP4, and the S19j Pro Xilinx guarded DCENT_OS-to-DCENT_OS self-update. The S9 sysupgrade archive remains receipt-only.
Risk: Experimental firmware can brick hardware, cause mining downtime, and may affect warranty coverage. Confirm the exact board and recovery path before any write.

Build and provenance receipt
| Website artifact label | beta20260709 |
|---|---|
| GitHub release pointer | v0.3.0, published 2026-07-13; commit a24f246. |
| Version mapping assurance | The GitHub release exposes the sysupgrade archives; the website set also includes the S9 SD image and checksum file. No signed receipt yet proves that every beta20260709 file maps byte-for-byte to tag v0.3.0, so this page records the pointer without asserting equivalence. |
| Builder image / digest | Not recorded in this website receipt. |
| Vendor input hashes | Not published here. |
| Package manifest / signature | 26985575eae77d56c490ceeb9054af012eab5ae59119cd20eaa70dd7e722df83The two sysupgrade packages contain an Ed25519-signed embedded manifest. No detached signature for the outer archives or SHA256SUMS.txt is claimed. |
| Independent rebuild | None published. |
Release history and changelog
As reviewed 2026-09-01, the public repository exposes 1 public GitHub release and 1 public Git tag. The table below is therefore the complete observed public history at that date.

Embedded Ed25519 manifest verified; no outer detached signature located | The verified package supports a guarded DCENT_OS-to-DCENT_OS update on am2-s19j. Public vendor-stock first installation remains an evidence gap, and public_beta_install is false in the source matrix. |
Download the SHA256SUMS list. The 3 receipts above come from the canonical registry. Verify the checksum and, where applicable, the embedded manifest before use.
Known limitations
- No verified prebuilt beyond the exact rows above belongs to this artifact ledger; that binary boundary does not change the 13 model-level release statuses.
- The S9 route remains lab-gated pending a witnessed current-artifact install, boot, soak and recovery capstone.
- The S19j Pro artifact has guarded DCENT_OS-source self-update evidence; vendor-stock first installation remains an evidence gap.
- No independent performance benchmark, security audit, SBOM or reproducible-build certification is claimed for this release.
