 # Dune implementation status
 
+## 14 October 2026 — Original quiet-phase Ecaz Cunning
+
+Removed the artificial Battle-only availability fence from printed
+current-turn Cunning. The original shared no-phase Nexus guard still blocks
+auctions, Battle, responses, Ambassador placement/arrival, revival and
+pending physical continuations; no public pause or interrupt is introduced.
+Private owner action, minimal legal bot adapter and actual table now reuse
+that source quote in any original quiet phase. Current chooser, phase,
+wallet, forces, ordinary leader slot and native continuation stay unchanged.
+
+New physical plays use strict version3 ordinary/captured custody with actual
+phase-bound events/history. Earlier unversioned/version2 Battle-only records
+retain exact keys, signature and phase grammar. Two actual prior native QA
+receipt formats are accepted unchanged. This is contract compatibility, not
+a new saved-room/recovery assurance campaign. Current-turn unused expiry,
+one-battle release, provisional return policy and Ecaz-only revival remain;
+no new roster/Skills/foreign-Ghola gate is opened.
+
+The actual Revival rejection fails before and passes after. Affected19-file
+union189/189, types/lint/build and thirty-one native API scenarios pass: both
+captured/returned-Tanks sources at actual Storm, Charity, Revival, Shipment,
+Collection and Mentat boundaries, all four minimal profiles in Revival/
+Shipment, native unused expiries and real Revival→Shipment→Battle release.
+Actual canonical-styled390px controls spend in Revival10→10, revive the
+executed Duke at deaths2 without an ordinary slot, and act during Harkonnen's
+Shipment without stealing it. Original Ecaz placement and Guild timing must
+finish through their own controls first. Native suffix reaches Collection
+or unused turn expiry once. No overflow/browser errors or saved/deployed
+room mutation.
+
+Deleted obsolete phase-only/blanket Harkonnen and incidental retained-hand
+pins rather than preventing newly legal early AI play. Initial smoke
+placement expectation was corrected to original end-Revival, not an invented
+Shipment decision. Isolated QA host mirrors real PostCSS/public assets and
+registers routing before the SPA fallback; initial host omissions were
+corrected, not application rules suppressed. Proof JSON remains outside Git.
+Final shared-Duke/capture/Ambassador internal guidance matches the bounded
+support. Final build retains existing module-deprecation, chunk-size and
+route-classification warnings.
+Broader combination/recovery review, calibration and deployed/publication
+acceptance remain open.

+
+Printed Cunning says to take Duke **for this turn**, without a Battle-only
+restriction. The original supported profiles now permit the private action
+at a quiet boundary in any phase. This removes the artificial phase-six
+fence; it does not open new rosters, modules, shared training, foreign-Ghola
+revival or an interrupt inside a committed parent.
+
+The existing shared no-phase Nexus guard still blocks original auctions,
+Battle, responses, Ambassador placement/arrival, revival, pending physical
+returns and other in-flight interactions. A new public pause is not created.
+The current chooser, phase, payment, force counters and native continuation
+remain unchanged by Cunning. One battle or unused **current-turn** expiry
+still sets Duke aside, without restoring an old captor.
+
+New physical plays use strict **version3**, with ordinary/captured custody
+and the actual phase in their private event/history. A command carried
+across phases is stale. Earlier unversioned ordinary and version2 captured
+records keep their exact Battle-only grammar and signature, rather than
+being reinterpreted as earlier-phase permission. Existing actual native QA
+receipts in both historical formats remain accepted. Future-phase history,
+invalid custody and invalid physical sources still reject.
+
+The original Revival rejection was reproduced, then the real same-disc
+Revival → Shipment → Battle/use path passes. The frozen affected nineteen-file
+union passes **189/189**, with types/lint/build. **Thirty-one native API scenarios**
+pass: captured/returned-Tanks Cunning in actual Storm, Charity, Revival,
+Shipment, Collection and Mentat windows; all four minimal legal profiles
+in Revival/Shipment; both native turn expiries; and original battle release.
+Actual production GameTable at **390px**, using the canonical stylesheet
+pipeline, spends Cunning in Revival and during another faction's Shipment,
+and returns a truly executed Duke from Tanks before Battle. Real Ambassador
+placement and Guild timing remain blocking until their own controls resolve.
+Wallet10→10, ordinary leader slot and Harkonnen's shipment turn remain;
+native battle release and unused expiry follow. No overflow/browser errors
+were observed in those working surfaces.
+The final production build retains existing module-deprecation, chunk-size
+and route-classification warnings. Shared-Duke, capture and Ambassador
+internal guidance now identifies this bounded support rather than a blanket
+capture exclusion.
+
+Obsolete phase-only and blanket Advanced-Harkonnen rejection pins, SSR
+wording and an incidental retained-hand assumption are deleted, not re-pinned.
+An ordinary legal AI may now spend the card earlier; that is not a printed
+requirement to retain it until Battle. No saved/deployed room is touched.
+This is not broader recovery, combination or complete-mode acceptance.
