Know what is stable before you depend on it
Review product version, capability status, open release gates, dependencies, evidence sources, known limits, and the exact boundary between local checks and external promotion evidence.
Capability and Release Center
This center is projected from the checked-in version manifest and capability stability registry. It does not infer a release from a passing local build.
Promotion reports are review inputs only. They do not mutate the manifest, approve a release, create missing G3/G11 evidence, or promote experimental work directly to stable.

Release history
Manifest history and the latest per-capability review date (2026-09-24) are shown separately from CI or operational promotion evidence.
v0.2.02026-09-26PreviewPreviewCoordinated 0.2.0 preview for the expanded language, numerical library, training workflows and toolchain. New sessions use the default language profile; saved feature choices and supported 0.1.0 artifacts remain readable. Capability statuses and artifact format versions are unchanged.
v0.1.02026-07-15ExperimentalPreviewPromoted the overall N/M product label to preview after the stable parser/statevector core, usable workspace spine, version-aligned tooling, and gate-transparent capability matrix were verified; experimental N/M 0.2 capabilities remain explicit opt-ins.
Strict G3/G11 evidence evaluator
The bounded evidence reader and recomputation tools are downloaded only when you choose to inspect an exact candidate.

Showing 58 of 58 capabilities.
Exact-candidate G3 evidence
The automated matrix stays open until 5 frozen suites produce all 12 Node shards, 4 Python shards, plus 1 production Chromium shard in one workflow run and attempt for one repository and commit. It accounts for 53 capabilities without converting a local run into remote evidence.
Separate hardware/provider evidence remains explicit: hardwareExecution.
Trust boundary: The JSON is not a cryptographic signature and does not replace retained GitHub run artifacts or real hardware/provider operations evidence.
The machine-readable promotion evaluator applies preview-to-stable-only, checks dependency closure, and only proposes candidates. It never edits the manifest or approves a release.
Reviewed production G11 evidence
The compact operational contract binds 6 reviewed production suites to one repository and candidate SHA, covering 7 capabilities without retaining raw events in the readiness report.
Capabilities without sufficient shared operational coverage remain on explicit evidence tracks: hardwareExecution.
Trust boundary: The JSON is not a signature, anonymous event counts do not prove distinct users, it does not replace each retained privacy-reviewed source export, and it cannot cover hardware without its separate provider evidence track.

- tooling
Why this is not more stable
- The local sidecar maximum-carrier performance gate is complete and configured on Windows/Linux Node 20/22; remote byte-parity evidence for the current candidate remains open.
- The 0.3 writer preserves N/M-only semantics and generic-circuit provenance as JSON IR; generic OpenQASM consumers do not interpret the sidecar.
- Permanent 0.1 and 0.2 readers remain available. Eligible documents migrate losslessly, while legacy documents with expanded compile-time structures require source recompilation when their version did not carry the required provenance.

- Contract
- 0.1.0

- platform
Why this is not more stable
- The strict preview-readiness mechanism now binds an account-grade provider decision, durable-store conformance, retained real-QPU provenance, rollback drill, 14-day operations report, byte-verified artifacts, and three owner reviews; no generally available production hardware provider or account system is bundled.
- Local and synthetic fixtures validate the frozen reader and CLI only. Real provider correctness, exact-candidate remote conformance, security approval, performance, browser E2E, and production operations remain open, so the capability stays experimental.
