- Move canonical specs into domain folders (identity, tbank, brokerage,
portfolio, instruments, banking, frontend-platform, backend-platform).
- Remove process specs; keep still-valid unique rules in openspec/config.yaml.
- Keep project-foundation behavior as app-shell and http-api-foundation.
- Archive account-top-positions without G4 by owner decision (descoped
review/QA recorded in process-record); sync portfolio-concentration and
portfolio-view.
- Group AI_INDEX by domain.
