Compatibility and capability matrix¶
Developer Preview 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. During preview, 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 0.1.0b4 | yes | PyPI and GitHub Release | Python 3.11–3.13; clean macOS ARM64 and native Ubuntu AMD64 public installs passed | no | no |
| Developer API 2026-08-24 | yes | public HTTPS OpenAPI | Protected contract/source gates and live unauthenticated-denial probe passed; positive independent-developer sandbox gate pending | Developer Preview routes yes; GA no | Global and customer-1 managed Cell at Coordinator source ee341285efa1a067555c83be2130926f755f41e9 / image sha256:e275d5e58f6c256ecd7bf3acac600b04c10e8e25f7468888b605dbd04e84b297 |
| Manual signed CLI assets 0.1.0b4 | yes | GitHub Release | macOS ARM64 and native Ubuntu AMD64 checksum, provenance, signature, and execution gates passed | no | no |
| Homebrew formula 0.1.0b4 | yes | geyserlabs/homebrew-tap |
Apple-Silicon public tap install, test, and audit passed; native Ubuntu AMD64 formula generation and integrity gates passed | no | no |
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. Publication does not by itself enable a production API or deploy a developer runtime.
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; they do not substitute for the independent non-implementer gate described in
Independent developer preview gate.
The Homebrew qualification receipt is public-tap commit
977a2ac9e5cb764dda97e0614b09de76dbbfaa31 and its successful
merged-main workflow.
