Release v2026.7.17.5 · canvascoding/canvas-notebook

Added Canvas-native Excalidraw live collaboration with multi-user presence, durable scene and asset persistence, reconnect/resync handling, and agent patch review after user intervention.
Added resilient chunked workspace uploads, workspace document previews and relations, searchable organization policy targets, and grouped chat tool batches.
Added a complete third-party license inventory, authenticated Legal downloads, exact native source evidence, and release-bound amd64/arm64 compliance artifacts.

Rebuilt both shipped Sharp versions against a replaceable shared libvips built from an exact source archive, and excluded all prebuilt @img/sharp-* payloads from Docker releases.
Pinned Debian, PostgreSQL and Python runtime inputs to immutable snapshots, versions and hashes, with schema-4 runtime inventories and a pre-manifest multi-architecture evidence gate.
Improved workspace-aware agent access, Markdown document references, chat presentation, plugin policy targeting, and upload progress handling.

Fixed workspace upload retries and finalization, repeated bulk folder moves, knowledge-graph document search, Markdown editor state alignment, and Marp export memory handling.
Synchronized all transitive peer and optional dependencies in package-lock.json and added a clean-install dry-run to the permanent release gate.
Bootstrapped CA certificates from the same signed Debian snapshot before switching APT to HTTPS, and replaced the redundant Debian libvips binary with explicit runtime dependencies for the source-built shared libvips.
Kept the complete libvips development-header set in the isolated dependency stage so both Sharp versions compile against that shared library without adding development packages to the runtime image.
Restricted Python PEP 639 license discovery to .dist-info/licenses, preventing architecture-specific bytecode in packages named licenses from creating false multi-architecture compliance drift.
