What to build: Implement 30048 — Hansei Review. Card text: "Gain 10[credit]. If there are any cards in HQ, trash 1 of them." Follow docs/adding-a-card.md for the definition of done: one contiguous hook block in rust/netrunner-core/src/cards/sg.rs, at least one card_30048_* Rust test, and implemented/has_tests flipped in game/cards_impl/sg.json.
Blocked by: 10 — implement sg remaining (this ticket's parent).
Status: fixed
2026-08-01: ON_PLAY hook. Which HQ card is trashed is the corp's choice; the engine takes the top of HQ, as Sprint does. Landed with ticket 10.
2026-08-01: Approximation lifted in ticket 39 — which HQ card is trashed is now a real corp decision (DecisionData::HanseiTrash).
