Honor allied Fremen victory and prevent deferred shipment deadlocks

Reciprocal allied Ecaz and Fremen with fighters in Sietch Tabr now satisfy that part of the Fremen final-turn victory, as explicitly clarified by the GF9 Ecaz/Moritani p15 FAQ. One public board quote drives automatic victory and the table guide; the chronicle explains the result. Other blockers, ordinary stronghold/BG prediction precedence, Guild fallback, advisor posture and concealed marker privacy remain intact. Habbanya symmetry and full mode/publication acceptance remain unfinished.

A genuine Advanced sample also exposed a pre-existing accepted Guild shipment which could never finish: allowance opened BG accompaniment and then hit the Ambassador arrival guard. Prior HEAD replay reproduced the exact 90-action failure. Fresh shipment preflight now rejects unsupported arrival combinations before accepting their pending windows. A valid legacy ordinary Guild allowance can return its unspent declaration to choose another destination; special parent/card receipts retain their separate gates. The change does not invent simultaneous reaction order or refund spent cards.

Independent rules/privacy/persistence review and focused engine/controls tests pass. Seventeen Fremen/Ecaz tests include all four profiles and authenticated final readiness/restart/concurrent writes. Shipment regressions cover pre-declaration immutability, supported arrival, malformed saved declarations and authenticated unspent return/replacement/reconnect/concurrency. All 4716 offline tests, types, lint, production build and 43 HTTP tests passed against unchanged source.

The original fixed seeds were repeated after repair and the exact failed snapshot resumed with documented new continuation seed 202609147: resume-advanced-202609147: 842 accepted, 109 guarded rejections, 22 periodic JSON restores; genuine-basic-202609145: 563 accepted, 14 guarded rejections, 15 periodic JSON restores; genuine-advanced-202609146: 806 accepted, 81 guarded rejections, 21 periodic JSON restores. All three finish and preserve physical custody/private views. These samples do not establish naturally reached allied Fremen special wins; a separate conserved browser final-turn fixture verifies the actual Ready-to-win transition, public guide/log, private hand and pending/finished refresh.

All 835 opening games and original seat/recovery records remain unchanged (902 after checks). All 869 rooms and records present after the reported outage also remain unchanged; database integrity and foreign keys pass. The healthy server and finished browser seat recovered without restart, reset or recurring automation. Full rules coverage and release gates remain open work.

+## 14 September 2026 — Fremen/Ecaz final-turn victory and deferred shipment repair
+
+The [explicit Sietch Tabr FAQ](ECAZ_VICTORY_RULES.md#fremen-final-turn-runtime-follow-up)
+now reaches automatic victory resolution: reciprocal Ecaz/Fremen allies with
+fighters there may satisfy the Fremen final-turn condition. The same public quote
+drives territory/blocker guidance; the chronicle explains a successful special
+win. Solitary/nonallied Ecaz, unrelated fighters and the unsupported Habbanya
+extension retain their existing exclusions. Effective advisor and concealed-marker
+presence, ordinary stronghold/prediction precedence, Guild fallback and existing
+no-Guild behavior are preserved. This adds no mandatory confirmation or schema.
+
+Independent source/privacy review found no blocker. Seventeen focused cases pass,
+including Basic/Advanced outcomes, all four AI profiles, JSON/private views and
+authenticated SQLite restoration before and after final readiness. Concurrent
+last-ready requests commit once; stale/finished requests do not write. Exact cards,
+Traitors, forces, elites and seat records are preserved. Final-turn positions are
+explicitly staged after genuine setup, including the reciprocal alliance and a
+turn-ten Fremen prediction, rather than claimed as natural full-game outcomes.
+The broader existing victory regression union passes 83 cases. A fresh browser
+room verifies the public guide, actual Ready-to-win transition, explanatory log
+and pending/finished refresh. Private read-only comparison confirms unchanged
+spice, cards, Traitors, leaders, forces, elites and seat records.
+
+A genuine Advanced sample also exposed the pre-existing [Guild shipment
+deadlock](DEFERRED_SHIPMENT_ARRIVAL.md): an accepted declaration could not pass
+an Ambassador/BG arrival overlap. Prior HEAD replay reproduced all 90 actions.
+Fresh ordinary/No-Field preflight and narrow, typed saved-declaration recovery
+now avoid the trap while preserving unresolved reaction-order gates. Independent
+review resolved an early No-Field window bypass and malformed special-marker
+handling; its 149-case union passes, including three authenticated SQLite cases.
+
+The exact failed snapshot finishes after 842 further accepted actions, with
+109 guarded candidates, on turn ten for Guild. The original Basic/Advanced seeds
+finish in 563/806 accepted actions with 14/81 guards, on turns seven/nine for
+Guild/BG. All 58 periodic JSON rounds, twelve terminal private views and physical
+custody checks pass against unchanged gameplay source. The Advanced runs form
+Ecaz/Fremen alliances, but neither uses shared Tabr or its special victory.
+The saved continuation uses a documented new random stream; no failed seed or
+snapshot was silently replaced. Simultaneous arrival integration remains open.
+
+The latest reported outage preserved all 835 opening games and original seat
+records. All 869 current rooms are backed up before final verification, and the
+finished browser seat restores correctly. The healthy server is reused.
+
+Browser and complete-sample evidence, types/lint/offline/build/HTTP results,
+source fingerprint, saved-game preservation and verified Git push are recorded
+with this checkpoint. The running server is reused; complete rules coverage,
+all combinations and publication remain gated.
