+**Prototyped / Partial.** The physical face changes ordered turns and explicitly
+supersedes Guild only for last. The [source review](JUICE_OF_SAPHO_SOURCE_UPDATE.md#movement-firstlast)
+and [Guild audit](JUICE_OF_SAPHO_ENGINE_AUDIT.md#movement-and-guild) distinguish
+ordinary reordering from a competing first declaration. No publisher answer
+settles that conflict. Under the standing recommended-choice instruction, the
+new composition provisionally admits a nonconflicting first after Guild waits,
+while preserving its native next-boundary timing. This is an implementation
+interpretation, not a retrieved official ruling or unconditional first priority.
+
+At a clean boundary before any remaining combined turn starts, the holder may
+move first in the native remaining queue even while Guild has an unspent turn.
+The existing native timing choice then opens before that reordered turn. Guild
+may take its own turn first or wait, retaining the relative order of every
+non-Guild participant. Existing `guildTimingGranted` permission stays recorded;
+waiting does not consume it or create another Karama response. An ungranted
+out-of-order timing attempt retains its original response. A granted current
+Guild turn remains unavailable for displacement. A Karama-locked timing privilege
+stays locked: Sapho changes order independently without restoring that advantage.
+
+The queue still includes only unfinished turns. Earlier completed turns, paid
+shipments, movement allowances and physical storm order do not reset. Existing
+pending decisions/responses, partly completed turns, reserved cards, no-op checks
+and Sapho-last protection remain. No new game marker or signature format is
+introduced. Reorder and discard before entering native timing; the existing
+Semuta suffix does the same only after original disposal finishes.
+
+The hand panel explains that Guild can still go ahead, and existing minimal
+policies consume the authoritative options. Frozen **7 files97/97**, types/lint/
+build and six original-action/rendered-table programmes pass. Actual public
+host/setup, original dealt Atreides Karama, cache1 and native wait use49 source
+actions. A real paid Richese1 Polar Sink prefix costing2 and explicit end uses55.
+TAKE/WAIT with and without that prefix use12–14 continuation actions; Emperor2
+and Guild1 shipments pay once, non-Guild order remains and every turn ends.
+Granted-current and canceled-TAKE branches fork from48 source actions before
+that wait, use3/2 native choice actions and11/7 continuations to finish the phase.
+The canceled privilege remains locked with its real Karama discarded once.
+Four profiles make eight legal holder/Guild proposals without strategy tuning.
+
+Only unopened original starting-deal/Spice positions and scalar lotteries are
+selected. No postdeal hand, force, wallet, queue, phase or timing receipt is
+installed. Actual GameTable and isolated Sapho controls render offered/busy,
+renewed native Guild choice, granted-current and locked states. Framework aliases
+and CSS stubs mean no browser clicks or visual/deployed acceptance.
+
+Frozen feedback repaired two fixture assumptions: an old LAST regression also
+expected first to remain excluded, and a completed Richese could still allow
+another faction's later response without repeating its movement turn. The
+exact two failures pass, then all97/types/lint/build/runtime pass together.
+The bounded source/continuation review found no need for another saved field
+or continuation. No application rule repair followed frozen feedback.
