v0.1.0

[0.1.0] - 2026-08-16

• Initial release: unified image_generate tool with config-driven engine routing, health-aware fallback, durable attachments, per-session quota accounting, and credential-reference key storage.

Added

• Unified image_generate tool: standard parameters (prompt/size/count/quality/style/engine) translated per engine; canonical value carries durable attachment references plus quota and routing facts; render embeds the images as attachment content blocks.
• Config-driven engine chain with two shipped presets (OpenAI Images gpt-image-1, Zhipu CogView cogview-3-flash) and any OpenAI-compatible endpoint; per-engine size maps, quality/style support, response format, and media type.
• Health-aware fallback router: chain order with engine-override promotion, consecutive-failure cooldown, disabled-engine skipping, and per-attempt audit views.
• Per-session quota accounting folded from the durable draw/generated session event (generation calls + image bytes), enforced before engine spend and before attachment storage.
• draw Typert Remote service (draw/status, draw/probe, draw/setCredential, draw/unsetCredential, draw/regenerate) with a hand-written host ./typert manifest shared with the client Remote contribution.
• Browser half: keyed tool.call.toolview result card (engine/quota facts + regenerate action) and a Plugins settings tab (engine chain, credential references, probes, quota limits).
• API keys stay credential references (environment-variable names) resolved per call through the official ctx.credentials seam — values are never logged or snapshotted.

Changed

• HttpRequest.body carries Uint8Array<ArrayBuffer>; the fetch transport spreads optional headers/body so exactOptionalPropertyTypes holds.
• Session.append uses the two-argument form (the pinned 0.1.0-rc.6 peers have no append-envelope option).

Fixed

• translateRequest defaults size/count for engines reached with a normalized request missing them.
