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

What is and is not recorded for beta20260709
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	`26985575eae77d56c490ceeb9054af012eab5ae59119cd20eaa70dd7e722df83` The 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.

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.

AVAILABILITY: RELEASEDMATURITY: EXPERIMENTAL

All 13 Antminer models in the registry are publicly released on the Experimental channel. Experimental is public firmware for testing and informed, non-critical use; it is not Stable or GA and is not recommended for an irreplaceable fleet.

The verified artifact ledger currently contains files for exact Antminer S9 + Antminer S19j Pro lanes. Binary scope is separate from release status; every lane retains its own installation and recovery limits.
