What is owned
The order picture plus the stated Tab5 quantity.
Which source wins?
How hardware works
Current M5Stack product, programming, schematic, protocol, and repository pages.
Story ideas
The family conversation and old source package, treated as ideas to check - not commands.
Before flashing
Re-check board versions, libraries, and release notes. These can change.
What came from the old package
The private source bundle supplied the "build one product, level it up" idea and strong manual patterns: project overviews, before/add/after states, step indexes, large visuals, expected/fix checks, and print layouts.
Sidequest keeps those patterns and removes adult utility work, real names, unsafe mechanisms, placeholder prompts, and wrong hardware assumptions. Private archive links are not published on this public site. The full decision trail is in the source map.

The official StackChan source can lag the released factory firmware and app.
Third-party StackChan gateway
kisaragi-mochi/stackchan-mcp is an MIT-licensed gateway for the 2025 M5Stack kit. It replaces device firmware and talks to a local client over WebSocket. It is not factory firmware, factory AI Agent, or StackFlow.
The Mac mini package is pinned at 0.17.0 as of
September 2, 2026. Installing the package alone does not change the
robot. See the
safe activation guide.
