Private pilot docs

One market record, two ways to use it.

Humans review approved pages and durable change cards in the private ledger. Agents search and retrieve the same chg_ records through MCP.

Manual onboarding

Applying does not create an account. An operator reviews the request, approves 1–5 public pages, creates a workspace key, and sends a one-time credential handoff.

The first successful scan establishes a baseline. It does not create a competitor change.
