 ## 8. What not to do
 
-- Do not copy component files from `trycompai/crm`. Most are shadcn/ui
-  originals — take them from upstream where they are canonical. Borrow the
-  compositions as ideas; the debt is credited in `NOTICE`.
+- Do not copy component files out of other people's repositories. Where a
+  primitive is a shadcn/ui original, take it from upstream, where it is

 - Do not open self-registration on the identity provider. It is shared with
   another application. PIG mints accounts itself, gated on an invite.
 - Do not put a production SSH key on the CI runner. Deployment is manual on

-## On borrowing from Comp AI CRM

-**Their component library was far deeper — 68 primitives to our 9 at the time.**
-PIG now has 22, including the ones that mattered: `data-table`, `command`,
-`sheet`, `drawer`, `sidebar`, `form`. The agent-chat compositions
-(`message`, `reasoning`, `thinking-indicator`) were rebuilt rather than copied,

+`thinking-indicator`) are ours, written inside `PiggyChat.tsx`.
 
-**`SourcedValue` / `Provenance` was worth adopting outright** — a dotted
