What to build: Implement 30061 — Clearinghouse. Card text: "You can advance this asset. When your turn begins, you may trash this asset to do 1 meat damage for each hosted advancement counter." 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_30061_* 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_TURN_START hook pushing a new clearinghouse corp decision (use/decline) once it carries an advancement counter — declining to keep advancing is a real choice, so both options exist. It is advanceable through the existing Card::is_advanceable text match. Landed with ticket 10.
2026-08-01: Ticket 40 — the window is now offered at every advancement count, zero included: trashing it for no damage is a legal choice and frees the remote slot. The rule-based Corp AI keeps its old behavior explicitly (decline at 0 counters, trash otherwise).
