Preflight ordinary movement through the existing arrival quote before creating new Ornithopter escrow or opening Ixian, Fremen and CHOAM prevention windows. An explicit legacy CHOAM decline can return an uncommitted unsupported arrival for another choice without consuming movement or touching forces, spice, cards or tokens. Preserve an existing Ornithopter and retire it exactly once on a legal replacement move. Keep dedicated Ambassador relocation handling and Karama cancellation validation before cost; unrelated exceptions remain atomic. Simultaneous Ambassador/Terror priority still awaits the recorded material interpretation, with no invented ordering. Add reusable offline faction-game samples with genuine Basic/Advanced setup, all four AI profiles, physical custody checks, JSON restorations, private traces and failed snapshots. Source-bound reports and input snapshot hashes make fresh and resumed samples repeatable; document that a resumed continuation starts a new seeded stream and does not prove input setup provenance. Validation: independently reviewed fresh declaration, native cancellation, supported single arrivals, legacy retry and card custody tests. Two production SQLite tests cover authenticated private restoration, stale/duplicate/wrong-owner rejection, resource conservation and concurrent version races. Typecheck, lint, 4583 offline tests, production build and 43 HTTP tests passed. Retain the initial failed check log for the corrected numeric-sort lint issue. All six fresh samples complete. CHOAM Basic 1054 actions/28 JSON restores, CHOAM Advanced 225/6, Ecaz Basic 91/2, Ecaz Advanced 523/14, all-three Basic 476/12, all-three Advanced 1303/35 with a turn-six CHOAM win. Combined Advanced has 46 guarded arrival candidates with legal alternatives. The exact prior 614-action failed snapshot separately finishes after 691 additional actions/18 restores and 39 guarded candidates. These are bounded paths, not complete faction or combination certification. Gameplay source hashes match the final checkpoint; later evidence-only documentation and recovery-test lint edits are explicit. After the reported outage, all 632 opening games and original seat/recovery records were preserved (665 after HTTP tests); integrity and foreign keys passed. Existing Ecaz and Ixian browser seats restored their same private hands, resources and pending choices after reload. This is browser restoration evidence, not a staged arrival-return claim. The healthy server was reused; no restart, database reset, recurring automation or publication. Verified source tree: 550221850f4802c41155f7bbc35d623965bc7db3330825636d50f26bb42868f8

Deferred movement and arrival validation
13 September 2026. This work repairs a development-game deadlock without assigning an unverified order to simultaneous expansion reactions.
Reproduced failure and source boundary
The all-three-expansion Advanced sample from checkpoint cab2f1c stopped on
turn three after 614 accepted actions. Tleilaxu declared three forces moving
to Carthag, where CHOAM had one force. That opened CHOAM's Baliset opportunity.
Carthag also held Ecaz's Fremen Ambassador and a concealed Moritani Terror
token. After CHOAM declined, the unchanged arrival guard rejected the
Ambassador/Terror overlap, trapping the already accepted declaration.
CHOAM's Baliset prevents movement into an occupied territory; it does not prevent shipment. Therefore its prevention window precedes actual entry. Successful prevention creates no arrival. Decline or cancellation allows the original move to be revalidated before any entry occurs. The latter is a composition of the printed effects, not a separate combined FAQ. GF9 CHOAM & Richese, p. 7
Ambassadors and Terror both offer optional effects after qualifying entry. The Ambassador FAQ interrupts the entrant's remaining work, but neither it nor the Terror rules establishes priority between the two. A targeted publisher/designer search found no additional priority ruling. Their order is material: a Fremen Ambassador can relocate forces, while Atomics kills forces in the marked territory. The current gate remains; no storm-order policy or lost-opportunity rule is inferred from tests. GF9 Ecaz & Moritani, pp. 5, 7 and 15
The user has been asked whether this overlap should stay gated pending an official ruling or use clearly labeled provisional storm order. No answer has been applied. The broader Ambassador and Terror contracts retain other arrival-order gaps, including Bene Gesserit reactions and child arrivals. An unavailable reaction combination is unfinished implementation, not a rule forbidding that move in the physical game.
Continuation contract
Fresh ordinary movement checks its arrival through the existing shared quote before opening native Ixian, Fremen or CHOAM prevention windows. An unsupported destination rejects the original action without saving a pending response or committing forces, costs or movement use. Supported single-reaction arrivals keep their existing controls and outcomes. Ambassador-generated relocation continues to use its own validated source and return path.
For an already saved CHOAM movement declaration, an explicit decline can return an uncommitted move to its original mover if the typed arrival validation rejects it. The chronicle explains the reason; the mover can choose another action without spending its movement. This recovery does not trigger an Ambassador or Terror effect, remove their tokens, or invent an arrival order. Any previously reserved Ornithopter stays in escrow for a replacement move; that exact card retires once when its use ends. No additional resources are spent by the return itself. Unrelated failures are not swallowed. Karama cancellation retains its existing preflight before any cancellation cost is spent.
Focused regressions and saved-state review cover both new declarations and legacy pending choices. The checkpoint report records final verification and sample results. This repairs continuation safety; complete simultaneous arrival handling, expansion acceptance and public starts remain unfinished.
Integrated sample evidence
The reusable harness repeated the six genuine-setup scenarios with base seed 20260926. All completed; the first five retain their previous action/restore counts. Combined Advanced now finishes on turn six with CHOAM winning, after 1,303 accepted actions and 35 JSON restorations. Its 46 rejected candidates (eight moves and 38 shipments) still encounter the explicit Ambassador overlap guard before using a legal alternative. This is not full combination acceptance.
Separately, the exact prior failed snapshot resumes through the saved CHOAM decline and finishes after 691 additional actions and 18 restorations, also on turn six. Its continuation uses a new seeded stream, not reconstructed earlier random state. It records 39 guarded candidates (seven moves, 32 shipments). The input snapshot SHA-256 and private traces are retained in the report. Both source-bound runs passed; subsequent result documentation changes do not change their gameplay source. The checkpoint verifies that source correspondence.
Existing browser rooms restored the same Ecaz Storm-opening choice and Ixian Richese auction, private cards and spice after reload. This checks outage recovery; the new movement-return path is covered by engine and SQLite tests, not a staged browser claim. All 632 opening saved games and original seat records matched the backup, and the healthy development server was reused.
