DCENT_OS Evidence and Readiness Status

DCENT_OS 0.9.0: exact-board Experimental status

beta20261002 has 29 exact-board status cards; 29 sets have retained or verified public static URLs. There are 17 raw SD images, 11 route-restricted archives and one BeagleBone developer payload. Only 13 raw-image rows have a lab SD route; 4 are inspection only while permissions conflict. Physical qualification is pending. The automated installer route is unavailable because its signed host does not resolve. Static file availability and installation permission are separate.

Historical July-registry status and evidence by exact Antminer model and control-board lane

Hardware	Release status	Verified prebuilt	Mining evidence	Install / recovery	Details
Antminer S9 Zynq/Xilinx am1-s9; redundant-slot NAND, with a separate removable-media boot route	AVAILABILITY: RELEASED MATURITY: EXPERIMENTAL	A verified S9 Zynq/Xilinx sysupgrade archive and a bootable SD image are listed in the historical artifact ledger.	The project platform matrix reports standalone cold-boot mining with pool-accepted shares on the BM1387 Zynq lane; this website does not claim an independent reproduction.	Bitmain's S9 recovery documentation distinguishes complete-board CRT0401/CRT0402 (JP4), CRT0302 (AB pads), and CRT0301 (no SD slot). The public DCENT_OS trial documents only the JP4 route; no other PCB revision inherits that authorization. The historical public evidence still lacks a complete witnessed first-install, soak and persistent-recovery capstone for this release. For the documented removable-media trial, power off, return JP4 to its photographed original position, remove the SD card, then boot untouched NAND. Other S9 PCB revisions require their own verified route. A witnessed persistent stock-restoration procedure for this exact release is not published.	Evidence page
Antminer S9 SE Ctrl_C43 / XC7Z007S, tracked separately as am1-s9se	AVAILABILITY: RELEASED MATURITY: EXPERIMENTAL	No verified S9 SE prebuilt binary is listed in the historical artifact ledger. The model still has AVAILABILITY: RELEASED and MATURITY: EXPERIMENTAL; build-output metadata is not a download.	The public source records exact model identity and detection evidence, but no callable production mining runtime or accepted-share proof for this lane.	The am1-s9se install row marks update, external media and general installation not implemented or denied. Do not use the S9 image. No model-specific installation write is authorized and no model-specific recovery-write route is published.	Evidence page
Antminer T17 Zynq/Xilinx am2-t17 with a PIC16 control path	AVAILABILITY: RELEASED MATURITY: EXPERIMENTAL	No verified T17 prebuilt binary is listed in the historical artifact ledger.	The source row is management-only and does not establish a historical accepted-share mining path on a live T17.	The am2-t17 install row has no implemented update or external-media route and denies installation. No model-specific persistent write or recovery procedure is authorized.	Evidence page
Antminer S17 Zynq/Xilinx; source mapping uses am2-s17p and must not be read as an S17 Pro install promise	AVAILABILITY: RELEASED MATURITY: EXPERIMENTAL	No verified S17 prebuilt binary is listed in the historical artifact ledger.	The historical evidence records a BM1397 source profile, not a reproduced accepted-share result on an exact S17 fleet unit.	The mapped source target has update and external media not implemented and installation denied. No separate exact-model route is published. No exact S17 persistent installation or stock-restoration procedure is authorized.	Evidence page
Antminer T17+ Zynq/Xilinx am2-t17plus with a PIC16 control path	AVAILABILITY: RELEASED MATURITY: EXPERIMENTAL	No verified T17+ prebuilt binary is listed in the historical artifact ledger.	The source identifies the BM1397/PIC16 route, but the public evidence does not establish accepted shares on an exact T17+ unit.	The am2-t17plus install row marks update, media and recovery not implemented and installation denied. No model-specific persistent write or recovery route is published.	Evidence page
Antminer S17+ Zynq/Xilinx am2-s17plus with a PIC16 control path	AVAILABILITY: RELEASED MATURITY: EXPERIMENTAL	No verified S17+ prebuilt binary is listed in the historical artifact ledger.	The source identifies the BM1397/PIC16 route, but the public evidence does not establish accepted shares on an exact S17+ unit.	The am2-s17plus install row marks update, media and recovery not implemented and installation denied. No model-specific persistent write or recovery route is published.	Evidence page
Antminer S19 Zynq/Xilinx source identity; no standalone exact S19 row exists in the canonical install matrix	AVAILABILITY: RELEASED MATURITY: EXPERIMENTAL	No verified S19 prebuilt binary is listed in the historical artifact ledger.	The source retains BM1398 identity and shared driver-path work, but this registry does not claim historical accepted shares on an exact S19 unit.	No standalone exact S19 row is published in the canonical install matrix. It must not silently inherit the S19 Pro or S19j Pro route. No exact-model persistent install or stock-restoration route is published.	Evidence page
Antminer S19 Pro Zynq/Xilinx am2-s19pro with redundant slots	AVAILABILITY: RELEASED MATURITY: EXPERIMENTAL	No verified S19 Pro prebuilt binary is listed in the historical artifact ledger. A build producer name is not a public release asset.	Historical cold-boot work produced nonce flow, but no pool-accepted share is proven for the historical native BM1398 path; historical electrical admission remains fail-closed.	The am2-s19pro update mechanism is experimental and lab-only. Public-beta installation is false and no general stock-firmware first-install route is published. Generated boot-media evidence is lab-only; no model-specific operator recovery procedure is published.	Evidence page
Antminer S19j Pro Verified artifact: am2-s19j Zynq/Xilinx; BeagleBone, Amlogic, CVitek and STM32MP15 are separate, unauthorized lanes for that file	AVAILABILITY: RELEASED MATURITY: EXPERIMENTAL	A verified S19j Pro Zynq/Xilinx sysupgrade archive is listed in the historical artifact ledger.	The project matrix reports accepted shares on the Zynq lane and historical runtime proof on BeagleBone; this website does not claim an independent reproduction.	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. No witnessed vendor-stock first-install and stock-restoration capstone is published for the exact artifact.	Evidence page
Antminer S19k Pro Amlogic am3-s19k, single-slot, NoPic lane	AVAILABILITY: RELEASED MATURITY: EXPERIMENTAL	No verified S19k Pro prebuilt binary is listed in the historical artifact ledger. Build-producer metadata is not a download URL.	The historical project ledger records a bounded Track-1 temporary-runtime accepted-share proof with terminal SafeOff, not an endurance or installed-image qualification.	The am3-s19k host-rootfs-window update is experimental and lab-only. No external-media route or public first-install procedure is authorized. Recovery is evidence-only in the source matrix; no general operator recovery runbook is published.	Evidence page
Antminer S21 Amlogic am3-s21, single-slot, NoPic lane	AVAILABILITY: RELEASED MATURITY: EXPERIMENTAL	No verified S21 prebuilt binary is listed in the historical artifact ledger.	The project matrix records accepted shares on an earlier runtime path; that result has not been reproduced on a verified historical public binary.	The am3-s21 host-rootfs-window path is experimental and lab-only. Stock AMLCtrl in-place installation remains blocked. No external-media or model-specific stock-restoration route is published.	Evidence page
Antminer S21 XP Amlogic am3-s21xp; package and exact topology evidence only	AVAILABILITY: RELEASED MATURITY: EXPERIMENTAL	No verified S21 XP prebuilt binary is listed in the historical artifact ledger.	The source records exact topology and package-format evidence, but the installed runtime remains management-only and no accepted-share proof is claimed.	The am3-s21xp install row has no implemented update mechanism, denies installation and authorizes no persistent update. No external-media, installation-write or recovery route is published.	Evidence page
Antminer S21 Pro Amlogic am3-s21pro, single-slot, NoPic lane	AVAILABILITY: RELEASED MATURITY: EXPERIMENTAL	No verified S21 Pro prebuilt binary is listed in the historical artifact ledger.	The source records an exact BM1370/Amlogic profile, but no historical accepted-share proof on a verified public binary is claimed.	The am3-s21pro host-rootfs-window update is experimental and lab-only, with no authorized external-media route. No model-specific operator stock-restoration route is published.	Evidence page

Reviewed 2026-08-29 against the public platform matrix. Exact board identity controls.

Use the current exact-board release cards and signed companions and installation and recovery decision guide. Development-key approval does not establish third-party kernel, boot or FPGA source correspondence or redistribution permission. The six retained historical scoped source bundles and their limits are listed in the release record. Additional Amlogic packages have partial source coverage; their full legal inventory and complete vendor/dependency correspondence are not established.

The evidence-state definitions below remain useful. The later model rows and machine-readable legacy API describe the historical July registry, not the full October download inventory.

How to read the evidence states

State	What it proves	What it does not prove
Artifact available	A named signed file and checksum are published for an exact miner/control-board lane.	It does not prove a generally validated first-install or recovery path.
Mining verified	Accepted pool shares are documented on named bench hardware.	It does not prove installation readiness or current-binary reproduction.
Guarded artifact	A file exists, but a required install, boot, soak or recovery proof remains incomplete or unpublished.	It is not production support.
Lab-only / bring-up	Source, enumeration, nonce, hashing or an earlier runtime path has evidence.	It does not create a public image or supported route.

Historical July artifacts: evidence first, file second

Antminer S9 Zynq/XIL

A signed sysupgrade package and SD image exist, and accepted-share mining is documented. The public repository still lacks a witnessed current-artifact first-install, boot, soak and recovery capstone. Review the exact S9 evidence page and release record. S9i, S9j and other control-board labels do not inherit this artifact.

Antminer S19j Pro Zynq/XIL

A signed Zynq/XIL package exists and accepted-share mining is documented. A guarded DCENT_OS-to-DCENT_OS update path has evidence; the first installation from vendor stock firmware remains open. BeagleBone and Amlogic are separate lanes. Review the exact S19j Pro evidence page and release record.

Historical July rows: no public artifact in that registry

These historical July rows do not describe current October file availability. The current record separately lists all 29 exact-board static file sets, including nine Amlogic packages and the BeagleBone developer payload. Read the exact card: inspection downloads, authorized lab workflows, existing-runtime updates and first-install-only archives have different permissions. No current-artifact physical boot, accepted-share, endurance or recovery qualification is claimed.

• Antminer S19: driver-path bring-up only; no accepted-share claim, public artifact or install route.
• Antminer S19 Pro: cold boot, chain enumeration and nonce flow; no current accepted-share proof or public artifact.
• Base Antminer S21/BM1368: earlier accepted-share runtime evidence; not rerun on latest binaries, no artifact, and stock AMLCtrl installation remains blocked.
• S17/T17 and every unnamed model/control-board combination: no public artifact is implied by source folders, shared chips or family names.

Historical July release and build boundaries

The GPL-3.0 Rust daemon, dashboard and Buildroot integration are public. A complete Antminer image also requires documented boot-critical vendor inputs that are not redistributed in the source repository. Read the source/build boundary, verify published checksums, and distinguish source buildability from complete-image provenance.

Before any persistent write

1. Match the exact miner and control-board lane.
2. Read the model evidence page and named release record.
3. Prove a known-good SD/UART recovery route on the actual test unit.
4. Back up the current state and record hardware revisions.
5. Do not test guarded firmware on revenue-critical hardware.
6. Report failures, short sanitized diagnostics and the exact artifact digest through the existing contact route; remove credentials and personal identifiers.

Historical registry API and current release catalog

The October publication catalog lists 29 current exact-board status cards and static file contracts separately from the legacy July API.

The canonical project record is available at /wp-json/dc/v1/dcent-os. It retains the historical July registry and separates artifact, mining, install and production fields. Use the current October catalog for static availability; do not merge the two evidence periods.

Historical July evidence heartbeat

Website review: 8 August 2026. Artifact set: beta20260709. No independent benchmark reproduction or independent security audit is claimed. Corrections can be submitted through the repository or D-Central contact page.
