Synth Workshop v0.3.0

Synth Workshop v0.3.0 is available for Apple silicon Macs. It is an ad-hoc-signed, unnotarized friends release; updates remain manual.

New

• Gemini 3.7 Flash (via OpenRouter) joins the collaboration model roster.
• Settings → Context manages agent limits, skills, MCP groups, cookbooks, and subagent compatibility.
• Local Reports can be created, sealed, reopened, compared, privately shared, or published as a committed revision.
• A typed approval broker covers paid compute, sidecar lifecycle, and credential access with durable, audited decisions.
• A generic Trace V5 inspector opens compatible sealed archives from Data → Traces and reopens them by digest after restart.
• The Optimizers plugin lifecycle installs, starts, and stops through the typed broker, including a bounded Craftax GEPA recipe.

Improved

• A dedicated Subagents rail keeps overlapping child threads separate from the parent conversation.
• Harbor live eval streams backfill before close and accept harbor-lite seals without synthesizing identity.
• Native Mermaid and systems diagrams render offline with the packaged Rust renderer and fail closed on invalid source.
• Visual templates are organized into families without changing stable template IDs.
• Chat/visual and Visuals list/preview splitters drag and persist independently, then stack at compact widths.

Fixed

• Pending approvals now expire as durable history instead of rendering as live cards with dead buttons after restart.
• Paid-compute approvals carry an explicit cap; exceeding it is recorded as a receipt violation rather than coerced to zero.
• Cookbook pin progress stays current, and Context command errors are shown instead of failing silently.

Download and verification
