-   * (v0.23, #16 P4a) Nation-management ops the LLM has proposed but the player
-   * has not yet resolved: a *pending proposal* list, as opposed to `pending`
-   * (the current round's queued player actions). A turn NEVER applies one —
-   * `applyTurnResult` appends the turn's `nationOps` to this list, and each
-   * proposal survives across turns until the player resolves it: confirming
-   * applies it (a rename changes `Nation.name` only — the id, its territory,
-   * its relations, and the player pointer all stay valid) and removes it;
-   * rejecting removes it without applying. Split/merge are declared for P4b
-   * and are a safe no-op on confirm until then. Always `[]` on a fresh game;
-   * rows saved before v0.23 load with this defaulted to `[]` (see server/db.ts).
-   * (The `NationOp` type lives in protocol.ts; the import there is type-only,
-   * so this file still has no runtime dependencies.)
