+| Guild discounted reserve shipment Karama | In bounded classic-faction Basic/Advanced tables, a separate prepayment response can cancel Guild’s or its ally’s half rate on an ordinary reserve shipment without canceling transport permission or income. The original authorized contributor split must cover full price; otherwise the Karama is spent but the uncommitted declaration returns and a replacement this turn uses full price. This conservative withdrawal is an implementation interpretation, not a found publisher procedure; independent Karama-purchased rates, cross-shipments and modules remain separate. | [Publisher distinction and selected ordinary-reserve policy](GUILD_RATE_KARAMA_RULES.md#selected-ordinary-reserve-interpretation--28-september-2026) |
 | Deferred shipment arrival | Quote unsupported ordinary arrivals before saving Guild interception. A validated legacy ordinary declaration may return unspent on the typed arrival error; corrupted declarations and special parent/card receipts are not silently cleared. This repairs continuation without deciding simultaneous reaction priority. | [Reproduction and bounded recovery](DEFERRED_SHIPMENT_ARRIVAL.md) |
