Compatibility and capability matrix¶
Production SDK/CLI 0.1 supports Python 3.11–3.13. The Python distributions are platform-independent. Native CLI qualification targets macOS Apple Silicon and Ubuntu 24.04 AMD64; Windows is not yet a declared native target.
API v1 is additive and date-versioned 2026-08-24. The current and previous SDK
minor are supported against the current server. Deprecations are documented for at least one
minor before removal unless a security issue requires immediate narrowing.
Runtime capability values are native, geyser_emulated, unsupported, or forbidden for an
exact framework/backend/adapter version/model profile/placement/privacy posture. Geyser Open is
the reference implementation, not a reason to overstate another adapter. The generated live
matrix and expiring qualification receipts are authoritative; this source table is explanatory.
| Surface | Implemented | Published | Qualified | Production enabled | Observed deployed |
|---|---|---|---|---|---|
| SDK/CLI 0.1.0 | yes | PyPI and GitHub Release | Python 3.11–3.13; clean macOS ARM64 and native Ubuntu AMD64 public installs passed | yes | canonical public channels |
| Developer API 2026-08-24 | yes | public HTTPS OpenAPI | Protected contract/source, customer-1 shared-runtime, fleet, and live unauthenticated-denial gates passed; owner-waived independent validation remains optional | Production and GA routes yes | Global and customer-1 managed Cell at Coordinator source ee341285efa1a067555c83be2130926f755f41e9 / image sha256:e275d5e58f6c256ecd7bf3acac600b04c10e8e25f7468888b605dbd04e84b297 |
| Manual signed CLI assets 0.1.0 | yes | GitHub Release | macOS ARM64 and native Ubuntu AMD64 checksum, provenance, signature, and execution gates passed | yes | canonical GitHub Release |
| Homebrew formula 0.1.0 | yes | geyserlabs/homebrew-tap |
Apple-Silicon public tap install, test, and audit passed; native Ubuntu AMD64 formula generation and integrity gates passed | yes | canonical public tap |
| SDK/CLI 0.1.0b4 | yes | PyPI and GitHub Release | prior beta qualification receipt retained | no | superseded by 0.1.0 |
The 0.1.0 qualification receipt is protected source
e567d9d6051b73d0fd4531a75245b65730c0790a and successful signed
release workflow 32866021028.
The workflow reproducibly built both Python distributions and both supported standalone targets,
published the two projects through PyPI Trusted Publishing, produced SBOMs and provenance, and
verified all retained artifacts during keyless signing. Follow-up qualification passed clean
public-index install/uninstall and downloaded standalone execution on Apple-Silicon macOS and
native Intel Ubuntu AMD64. All 16 retained Sigstore bundles verified against the exact protected
workflow/tag identity.
The 0.1.0b4 qualification receipt is the successful protected-tag
release workflow for source
commit b105031a2de27633a183d82729b375168b138fcf, followed by clean installs from PyPI and
execution of the downloaded standalone archives on Apple-Silicon macOS and native Intel
Ubuntu. All 16 retained Sigstore bundles verified against the exact protected workflow/tag
identity. The stable release is rebuilt and re-signed from its own protected v0.1.0 source tag;
the beta receipt is retained as prior qualification evidence, not reused as the stable artifact
identity.
The Developer API deployment receipt is Cloud Build
844f8123-f853-4c59-bdbc-a364da4d2517, which produced the immutable Coordinator image above
from the recorded clean merged source. The live OpenAPI document reports title
Geyser Developer API, version 2026-08-24, and the unauthenticated capabilities route denies
access with HTTP 401. Those observations establish publication, deployment, and fail-closed
authentication. The product owner waived the independent non-implementer exercise as a mandatory
release gate on 2026-08-25. The optional independent validation remains
public, and no independent receipt is claimed.
The Homebrew qualification receipt is public-tap commit
437ff79041c6d763a2991e47d16794cf9e4f94e8 and its successful
merged-main workflow.
The stable documentation receipt is source e567d9d6051b73d0fd4531a75245b65730c0790a,
