# HSG Amendment Process

Principles never disappear. When understanding evolves, the change is
recorded as an amendment — an append-only entry that references the
amended principle by id. The original statement remains permanently
visible.

## Amendment kinds

- **clarification** — restate the original meaning more clearly.
- **extension** — broaden scope without contradicting the original.
- **supersession** — the original is retired in favor of a new
  statement; both remain visible.
- **context-note** — record historical context around interpretation.

## Rules

- Append-only. `amendmentAppendIsSafe(before, after)` proves it.
- The `originalStatement` field is frozen; only new amendments may
  add to the record.
- Amendments never overwrite the ratified volume prose — they
  accompany it.
