+# Ordinary bribes after Mentat opens
+
+## Timing cutover — 26 October 2026
+
+**Prototyped / Partial.** Quiet Mentat Pause now permits an ordinary non-allied
+bribe. The payer spends current spice; the recipient's share stays in the
+existing deferred `bribes` supply until the next actual Mentat opening. The
+current opening has already collected its snapshot. A late payment never
+creates immediate recipient cash or a second collection in this phase.
+
+## Source and interpretation
+
+The publisher [base rulebook, printed12 BRIBERY](https://www.gf9games.com/dunegame/wp-content/uploads/Dune-Rulebook.pdf)
+allows non-allied deals subject to the listed rules/component restrictions;
+it supplies no separate Mentat payment ban. Its indexed passage was checked for
+this cutover. The [November2020 FAQ](https://www.gf9games.com/dune/wp-content/uploads/2020/11/Dune-FAQ-Nov-2020.pdf)
+indexed Advanced clarification retains deferred recipient spice; a fresh direct
+fetch returned403, so no dedicated new FAQ Mentat-payment ruling is claimed.
+The earlier checked FAQ source remains recorded in [bribe controls](BRIBE_CONTROLS.md).
+
+The supplied authorized Advanced physical16/printed14 BRIBERY passage was read
+for this cutover: collection happens only at each turn's Mentat start. Its
+listed limitations also supply no blanket Mentat payment ban. Under standing
+14October choose-recommended priority, preserve the app's existing opening-only
+collection in both modes and carry a later payment to the next opening.
+Basic keeps its existing deferred-receipt protocol rather than adopting new
+Advanced faction rules. The Basic late-payment interval and source/online
+cutover remain explicit software interpretation, not a dedicated publisher
+clarification of this exact late-payment scenario.
+
+## Connected behavior
+
+`game/bribe-options.ts` removes only the inherited phase8 ban. Existing game,
+pending-choice, Inflation Double, nonally, amount, uncommitted-funding and
+Bureaucrat checks remain. The original `bribe` packet, payer debit and recipient
+receipt producer are unchanged. The existing phase8 opening collects receipts
+once; native next-turn initialization leaves late receipts intact. Incoming
+deferred spice cannot fund another bribe or the next auction before collection.
+
+The existing [Truthtrance bribe contract](TRUTHTRANCE_BRIBE_PROMISES.md) now spans
+phases0–8. Current-turn No survives the collection opening and caps subsequent
+late payments until actual turn advance. Unpaid Yes prevents finishing Mentat,
+rather than ordinary Collection. New Yes reopens only its already-ready Mentat
+payer; Collection readiness stays intact except before a known automatic
+Inflation flip to Double. That known closure requires payment before Collection
+Ready and reopens an already-ready payer when a new Yes is bound.
+An unknown future opposing choice is not fabricated for a witness.
+
+Only actual payer payments record promise progress. Later recipient collection
+does not fulfill or pay the same promise again. Existing terminal historical
+answers remain terminal; no save migration, retroactive promise reactivation or
+database rewrite is performed.
+
+Ordinary and promise controls explain the opening boundary and next-turn late
+receipt. Guides support Mentat and reject callbacks after their original phase
+changes. Exact native packet/event, current options, room/busy and ownership
+guards remain. All four minimal policies use the newly legal guided payment;
+strategic negotiation and difficulty calibration stay deferred.
+
+## Evidence and remaining gates
+
+`tests/fixture-mentat-bribes.ts` derives real phase7/8 and next-turn openings
+from the existing original H/A/E base33 source. Native cases are in
+`tests/mentat-bribes-runtime.test.ts`; existing controlled bribe and promise
+tests retain their labels. One controlled token-only supplement in the old
+Truth runtime file covers a known future Double closure and does not claim a
+native CHOAM placement history.
+
+The frozen v2 batch passes **13 files,119/119**, types/lint and the production
+build. Six native gameplay paths produce26 GameTable SSR renders/two actual
+guide callbacks. Original H/A/E base33 Basic32/Advanced35-action sources reach
+quiet first Mentat; late3 spends E10→7 and survives real next Storm/Collection
+before exactly3 is credited at the next opening. Advanced city income2 is
+separate. Other paths reopen only an already-ready phase8 Yes payer, carry a
+phase7 Yes unpaid across Collection, retain a cumulative No across the opening
+until actual turn advance, and allow an already-ready ordinary late payer.
+All33 cards remain; all four minimal profiles use the legal payment guide.
+These are local native/SSR/callback results, not browser or deployed acceptance.
+
+The first batch's quick check passed, then four new native cases exposed a
+remaining parser phase gate. The parser repair and ready-before-known-Double
+closure passed five focused cases; the unchanged repaired tree then passed the
+complete v2 selection/build/runtime. Its source snapshot is
+`ea2e7ed4055807a02cd3a0bb1b96706097c37a306513a8b55ff22554c6b1eb9d`
+(3128 files); final evidence prose is bound separately by the checkpoint manifest.

+journeys/HTML: adjacent `20261026-mentat-bribes-runtime/`.
+
+Broader late-phase skill/faction/module compositions, original Inflation
+placement/closure journeys, browser/mobile/deployed and final assurance remain
+required. No complete faction/mode or publication acceptance is certified.
+No saved-game/database/server/reset/restart/deployment operation is performed.
