Design system philosophy
fix(retraction): correct 13 earlier-this-session Correction callouts that were checked against a stale local branch — app-orchestration-command and os-orchestration are real on canonical origin/main (CommandCentre server + scaffold respectively), app-privategit-* license is genuinely AGPL, app-privategit-design's MCP endpoint is real; this session's local checkout diverges from canonical for these paths

The substrate engine (`app-privategit-design`) reads this vault and serves it as a public showcase, a DTCG bundle, an AI-readable research surface, and a Model Context Protocol (MCP) server.

(Correction, 2026-08-02: no `/mcp` route or MCP module exists in the current `app-privategit-design` build — `grep`/`find` for MCP code in the crate return nothing. Git history shows an MCP endpoint with 4 tools *was* added at one point but is absent from the current checked-out HEAD — a shipped-then-removed feature, same pattern as the deleted collab feature found repeatedly elsewhere in this corpus. This same claim recurs at "the same MCP endpoint" further down and in this article's own See Also section — all three references are affected. Flagged, not resolved.)

Re-checked against `origin/main`: the MCP module and its `POST /mcp` route are real — see [[mcp-ai-agent-consumable-design-systems]]. This claim holds.) ## Three structural inversions of the Enterprise-tier pattern
