# Function: formable_purchase_deliver_offer
# Purpose: Called from a <TAG>_buy_core_state remove_effect once the negotiation timer elapses.
# Sends formable_buy.1 to the state's holder. cancel_trigger only catches the two terminal cases, so
# the sale is re-validated here against the full gate and refunded through the else branch.

# Function: formable_purchase_cancel_offer
# Purpose: Releases the offer lock and returns the escrowed purchase price to the buyer when an offer
# never reaches a holder, either because the timer was cancelled or because it lapsed on delivery.

# Function: commit_special_formable
# Purpose: Commit the AI to a special (non-decision) formable. Caller sets special_formable_id first
# (ids >= 100, table in .claude/docs/formable-reference.md). Size 1000 outranks every decision
# formable's ratchet gate, so the AI never leaves the special identity for a decision formable.
