The FerrFlow CLI has been open source since the start, but its documentation was not. The pages lived in the private repo that builds ferrflow.com, so spotting a mistake in them and being able to fix it were two very different things.
They now live in docs/site of the public FerrFlow repository, next to the code they describe. Every page served under /docs, current and frozen, is in there.
To fix something, open a pull request against that repo. The pages ship in the @ferrflow/doc package and the site picks them up at build time, so there is nothing to do once the change is released.
The frozen per-version snapshots came along too, and they stay frozen. docs/site/docs-v5/ records what FerrFlow v5 actually documented, mistakes included, because anyone still pinned to v5 reads those pages to understand the binary they are running. CI rejects a pull request that edits one and points you at the current docs instead.
