v0.0.6

Added

• zai provider — Z.ai (GLM) API support via the GLM Coding Plan endpoint (https://api.z.ai/api/coding/paas/v4). Includes glm-4.7 (default), glm-4.5-air, glm-5.1, glm-5-turbo, and glm-5.2 models. Auth via ZAI_API_KEY env var or zai_api_key in ~/.bo/auth.json.

Changed

• Untitled leaves now report title: null instead of an empty string in JSON output (bo show, bo status, bo query --json) and in the manifest. Existing manifests load unchanged.

Architecture (non-user-facing)

• Tree/branch/leaf metaphor committed to types — Leaf/Branch domain entities (was LeafRecord/BranchRecord), validated Title/Url newtypes replace bare String aliases.
• Frontmatter serialization unified on typed structs (LeafFrontmatter/BranchFrontmatter) with golden-tested byte-stable .md file output.
• On-disk formats (manifest.json, config.json, .md frontmatter) unchanged — this is an internal type-strengthening, not a format migration.
