Synth Workshop v0.7.3

Synth Workshop v0.7.3 adds reproducible ALFWorld local training support and hardens hosted CISPO admission while preserving the v0.7 packaged workflow.

Training and containers

ALFWorld local MLX SFT runs against an official artifact-backed container.
A produced SFT artifact can warm-start local CISPO with exact artifact lineage.
The packaged release receipt binds Workshop and the combined Containers candidate.
External catalog runtimes can expose dependency-aware health probes for Craftax-style façades.

Hosted safety

Hosted CISPO requires a durable authenticated canary receipt.
The environment-variable admission bypass was removed.
The currently available canary is not admissible, so hosted CISPO remains fail-closed.

The Workshop Rust, static, visual, accessibility, and Playwright suites passed.
ZIP and DMG round trips both reported version 0.7.3 and passed strict deep-signature verification.

Craftax host-stack restart/reconciliation passed with immutable source and artifact receipts. Final Workshop benchmark acceptance still requires a published registry image pinned by manifest digest. Live Harvey/OpenRouter evidence and an admitted hosted CISPO run remain follow-up validation and are not represented as passing.
