CHOAM Nexus Cunning runtime

The historical checkpoint below integrated native CHOAM Cunning with five Worthless effects in Basic and Advanced. The separately verified 1 October 2026 nexus-kull profile adds bounded source-aware Kull, with broader verification Partial. The source contract lists all six printed effects, not a full-family release. The older printed Kull profile still excludes Nexus; other Nexus previews still reject Kull. CHOAM Secret Ally and Betrayal retain separate contracts. No profile silently enables new choices in older games or certifies complete CHOAM, Nexus or expansions.

Original five-effect Semuta composition — 11 October 2026

Fresh native Richese semuta --nexus-cards now offers the original CHOAM Cunning fuel discard for Kulon, Trip to Gamont, Baliset, La La La and Jubba. Actual qualifying closing draw leaves CHOAM unallied with its own Nexus. The original quote chooses any eligible canonical held Treachery fuel, not a manufactured named Worthless card. Native cancellation retains that fuel and the already-spent Nexus; no fuel is discarded or offered on prevention.

Allowance retires the original Cunning receipt and discards its exact fuel. The existing five Worthless continuations carry an optional completed nexusEvent, bound to original owner/card/effect/targets and parent flags. Old printed signatures remain unchanged when the optional event is absent. Cunning cost faces remain private through the neutral offer; singleton Commit acquires the original descriptor and resumes the original selected effect once. The original ordinary range bonus, typed return and closing Mentat owner, stopped move/free revival, or threatened-territory storm suffix is not replayed. Jubba protects CHOAM forces, never storm-covered spice; unprotected own/opposing forces and both covered spice piles retain their original losses.

Actual native Kulon exposed the omission before cutover: fuel discarded, Nexus spent and bonus applied with no Semuta opportunity. After cutover, the cost pauses before that one native bonus. Two proactive and24 reactive runtime cases cover Basic/Advanced claim/pass, four legal profiles, full hands and original Skills/Tech/Strongholds closing. Actual Advanced storm uses its revealed original card distance, not Basic dialers; the fixture now uses that real source rather than an unreachable Basic-only boundary. The affected unit union passes120/120 across9 files.

Styled390px human controls complete all five original quoted powers through native Allow and full-hand Commit. Slip Tip, Hajr, Stunner, Maula Pistol and Crysknife remain their actual printed categories. Gamont returns one elite and restores its original Finish; only that Finish assigns Stronghold claim2/turn3. La La La leaves3 Tanks/0revived/10spice before a legal paid-two revival reaches1Tank/2revived/ 6spice. Advanced Jubba keeps3 protected forces, loses3 other CHOAM and4 opposing forces, destroys both covered spice piles and reaches original market. Acquired projectile inspector and current preview guidance were inspected. Own probes/service/tab are removed; existing games/stores/PDF and deployment are untouched. Kull, unrelated parents/modules and complete-mode/public gates remain separate. No comprehensive custody/privacy/recovery campaign is claimed.

Printed native cancellation cost — 11 October 2026

A distinct printed Karama canceling any of those five native printed or Cunning powers now offers its own exact public discard before cancellation completes. karamaChoamWorthlessDiscard preserves the original response and live declaration/ordinary movement, free-revival, storm or closing-Mentat parent. The original cancellation quote remains authoritative; state signature fields bind the current declaration, source receipt and affected physical counters. Old unrelated response-cost signatures are unchanged.

During the cost offer, CHOAM's declared card remains held and a Cunning receipt remains pending with its Nexus spent. Claim/pass restores the original response, cancels once and resumes the same native suffix. The original fuel is not a Semuta target: acquiring the cancellation Karama cannot grant range, return a force, stop movement/free revival, protect the storm or refund Nexus. Printed source retains its held Nexus as well as its named Worthless.

Actual before-cutover Kulon canceled immediately without offering its spent Karama. Afterward the cost pauses and all views work. Thirty native runtime reactions cover five families, claim/pass/full hands and four legal profiles; an additional actual Basic Kulon claim retains fuel and leaves range denied. The affected unit union passes179/179 across10 files; types/lint pass. Styled390px Gamont declaration→Cancel→Commit preserves the Emperor's elite at Arrakeen/reserves4 and CHOAM's Hajr; only original Finish assigns Arrakeen to Emperor at claim2/turn3. Jubba cancellation→Commit retains Maula Pistol; original Continue loses all6 CHOAM/4 opposing counters, removes both covered spice piles and reaches native market. Actual acquired Karama inspector and updated preview guidance were inspected. No Kull, unrelated source parent, new module/public gate, saved-game change, deployment or assurance campaign.

Physical cost and timing

An unallied CHOAM player holding the CHOAM Nexus chooses one actual held Treachery Card and one supported effect. The card need not have the corresponding Worthless name. The engine preserves its original identity, ownership and any reservations; it does not manufacture a named Worthless card or grant a turn-long conversion ability.

The existing timing and target controls remain authoritative:

• Jubba Cloak protects CHOAM forces in one threatened territory during its moving-storm response.
• La La La prevents a selected player's free force revival, including the existing response before a mixed free/paid revival commits.
• Baliset prevents movement into a CHOAM-occupied territory, including the existing declared-movement response. It does not prevent shipment.
• Kulon adds one territory of range before an available CHOAM move, without granting another movement action. The fixed Ornithopter-range combination retains its existing ruling boundary.
• Trip to Gamont returns one selected opposing physical force during Mentat. Existing typed-counter, No-Field and deferred-victory behavior remains in force.

Playing Cunning spends its physical Nexus card and opens one ordinary CHOAM-effect Karama response. Cancellation leaves the selected Treachery Card held and the Nexus spent. Allowance discards the actual selected card once and applies the chosen effect. Its real discard category governs other consequences, including applicable private Ecaz income; the selected Worthless effect does not change that category.

Controls, policy and private information

The engine's owner-only choamWorthless.plays separates source, effect, the actual card, an optional Nexus event, and a blocking reason. The original printed-card descriptor remains available. Shared options construct ordinary card actions unchanged and add the explicit effect/event only for a Nexus use. They fence stale events, actor identity and current interruptions, and use the server's source-specific blocking reason.

The cost selector is reused by the existing storm, revival/range, movement prevention and force return panels. It names and inspects the real cost card separately from the effect, supports transport-busy state, and exposes blocked choices without offering an illegal action. The new Kull panel uses this source-aware convention only in its explicitly enabled reaction profile; generic proactive Nexus Kull remains unavailable. Public reaction windows and controls disclose neither hidden Nexus ownership nor CHOAM's private cost list.

All four bot profiles use the same projected plays. They preserve printed effects first, then prefer lower-value legal Nexus fuel, retaining their existing public-target policies. Easy's existing policy of allowing free revival remains unchanged. The ordinary Trip to Gamont preservation policy still reserves that printed card during a closing market or cash-in even though playing it must wait for the next legal window. These are legal policy extensions, not a new AI calibration claim.

Existing reactive windows depend on public circumstances rather than whether CHOAM holds a matching card. Cunning uses those same windows, so holding a private Nexus card does not introduce an identifying public wait. Opponents receive no private cost list. Saved engine receipts, cancellation and physical disposal are handled by the engine; consumer code does not reconstruct an opportunity from card names or old saves. Later bounded Semuta integration does not establish every Cunning fresh-discard composition. Native Cunning remains subject to its ordinary Karama response; neither this checkpoint nor the separate printed-Kull preview grants blanket Nexus immunity.

Bounded Nexus Kull profile

Create a fresh local nexus-kull room through genuine setup with two to six ready seats, native CHOAM plus classic factions, Basic or Advanced, exactly the CHOAM/Ix Treachery decks and Nexus alone. initializeNexusKullGameForAudit identifies this capability with nexusKullPreview and the shared kullPreview. No optional module beyond Nexus, other expansion faction, Semuta or Richese Betrayal is admitted. The kull profile remains printed-only; existing saves and other Nexus previews do not inherit the new choice. The visible warning and closed public expansion start gate remain.

At the canonical validated Karama opportunity, CHOAM's private kullReaction.plays contains { source, effect: 'kull', card, event, blocked } choices. The old cards field is removed. Printed source requires actual held Kull Wahad; Nexus source requires unallied native CHOAM's physical CHOAM Nexus and any eligible actual Treachery fuel. Canonical unique custody, reservation exclusion and source-specific own-promise feasibility apply before acceptance. A Karama fuel discard does not also activate Karama. Other viewers get empty plays and identical public event/actors/purpose regardless of secret Nexus identity or fuel; controls never infer an offer from the hand.

Use submits { type: 'kullDecision', event, source: 'printed' | 'nexus', card }, with source required even for printed Kull. Decline submits { type: 'kullDecision', event, decline: true }. There is no old omitted-source fallback, extra client-selected effect/target/price/Nexus ID or proactive any-time Kull action. The event is the pending attempted-play event, not a guessed generic Cunning receipt.

Outcome	Physical Nexus	Selected fuel	Interrupted original
Decline	Retained	Retained	Resume exactly once with normal costs.
Accepted Nexus declaration, response pending	Spent once immediately	Held/reserved pending success	Held/reserved; a distinct eligible counter may act before the ban.
Kull prevented	Remains spent; no refund	Retained under existing exact-cost phase prevention	Resume exactly once; no Kull activation ban.
Kull succeeds	Remains spent	Discarded exactly once	Retained unplayed; effect/additional costs and special once-use unspent; activating player phase-blocked.

Printed declarations spend no Nexus and retain their existing printed-card settlement. The original attempted card cannot serve as its own counter. Advanced BG originals are intercepted before conversion/discard; decline or prevention resumes their separate ordinary conversion, while success keeps the original Worthless card. A distinct BG counter has its own conversion ownership. The successful ban is stamped to turn/phase and applies to activations, not holding, trades or nonactivation disposal.

Distinct-counter priority, pre-conversion custody and deferred unpayable-overbid recovery are the user's selected policies. The neutral offer and Nexus-spent-at-accepted-declaration boundary are existing application conventions, not a located publisher response-order ruling. The private non-CHOAM unfunded Karama-dependent bid fence remains before commitment, independent of hidden Kull/Nexus ownership; no restart, free lot, funding remedy or numeric UI cap is introduced. Live original/fuel/counter promises must remain satisfiable; unsupported continuations are guarded before offering rather than releasing a promise.

The saved pending Kull and existing Cunning receipt/history must bind chosen source/fuel, accepted Nexus spend and the exact original typed continuation, including suspended BG or Karama parents. Refresh must not replay raw actions, double-discard, refund Nexus or restore a mutable whole-Game snapshot. Stale, foreign, malformed, deleted or orphaned source/receipt/history/original ownership must fail before view/normalization/action/SQL writes. Completed historical receipts do not require old spent cards to remain forever in discard.

Five-part status for the new interaction

Area	Status	Bounded claim
Implementation	Partial	Explicit source-aware interception and fresh-profile boundary; wider faction/module continuations and complete games remain outside scope.
Player controls	Partial	Actual private fuel selection and fuel/Nexus inspectors, source-required Use, distinct counter/allow and Basic/Advanced phone refresh pass; wider accessibility/presentation acceptance remains open.
AI	Partial	Four profiles use private canonical legal plays and existing counters; no full strategy/calibration claim.
Documentation	Partial	Source/effect, real fuel, spend timing, user policies, privacy protocol and old/new profile boundaries are recorded; publisher clarification/full-family acceptance remain open.
Verification	Partial	Types, lint, 6,022 offline tests and build pass, with actual fresh CLI entry, source runtime, Basic/Advanced phone success/prevention and saved physical-cost proof. Local HTTP is 49/55, not green; wider/deployed acceptance remains open.

The frozen suites cover non-Worthless/printed fuel, successful phase ban, distinct prevention/original resumption, BG preconversion, decline and identity-neutral offers, physical conservation, reservations/promises, four legal bots and authenticated SQLite restart/races/immutable malformed or orphan rejection. Independent review repaired canonical descriptor trust, suspended native Nexus parents, nested parent-cost counters and CHOAM winning-payment coverage, including retained ordinary Karama with a canceled Cunning-effect block. Fresh setup excludes physical Sandtrout. Verified old printed-only counter saves receive a bounded immutable selection-binding migration; new Nexus-profile missing selections still reject. No source-omitting action shim or new-choice retrofit is introduced.

Actual nexus-kull CLI continued four owned fresh QA rooms from version 5 to setup 6. Genuine setup/Storm/Spice completed before conserved pre-action resources were arranged. Standalone runtime and 390-pixel controls prove Basic/Advanced weapon fuel Use followed by success or a distinct printed counter: Nexus spends once on declaration, success discards fuel/retains original/bans the actor; prevention retains fuel/leaves Nexus spent/resumes the original once. BG success keeps Baliset before conversion; prevention resumes its normal conversion. Refresh and direct saved-state checks preserve exact inventory, source history and unchanged spice. Fuel and CHOAM Nexus inspectors show their distinct actual components; rival views expose no private fuel inspector.

Local built-worker HTTP passes 49/55: four POST 503s and two timeouts retain the known Wrangler-dev limitation. Proxy-free container CI and live deployment are recorded separately after the checkpoint push. Full optional-module/faction modes, calibrated AI, complete games and deployed acceptance remain separate gates.

Historical five-effect recovery evidence

The saved receipt binds the physical card, selected effect, original phase and owner, declared target and the specific suspended movement, revival, storm or Mentat context. Independent review reproduced legal-looking replacements of a pending movement quantity, revival quantity/price and storm distance. Those edits now reject before reads, automatic normalization or either outcome can write state. Historical completed records do not freeze unrelated future resources.

Actual paid Nullentropy searches can suspend and restore the response. If CHOAM legitimately consumes the selected card in an intervening cash-in, Cunning fizzles with its Nexus still spent and resumes the original operation once. Cancellation retains the card and applies the existing phase block. Production SQLite tests cover private refresh and simultaneous cancellation versus the final pass; exactly one version wins.

Historical five-effect verification

Five consumer regressions at that checkpoint were in controls and bots. They exercised actual fixture-generated windows for all five supported effects, submitted source actions, the real cost-card inspector, Kull unavailable outside the new profile and reserved cards, stale events, actor/interrupt fences, private-field traps, all four policies, and unchanged printed actions. The combined consumer, existing Worthless/storm/movement/Gamont, Nexus guidance and reference selection passed 150/150 tests. Type-aware lint passed for owned code/tests at that checkpoint; its then-existing nine local links resolved. The log is /tmp/dune-choam-consumer-tests.log. This is preserved historical evidence, not a fresh check of the new Kull interaction.

That checkpoint's integrated checks passed: types, lint, all 4,042 offline tests, production build and 40 HTTP/session tests. Thirty new cases covered the pure receipt, engine, consumers, independent saved-parent review and production SQLite matrices. Logs are /tmp/dune-choam-{check,build,http}.log. These results are not rerun totals or proof for the later Nexus Kull profile.

Two isolated three-seat browser rooms passed actual phone declarations, desktop/phone response inspection and all six private refreshes. GDP8NNRE version 4 allowed Baliset: the pending two-force movement was prevented, the three original source forces remained and the real Stunner payment was discarded. WJTUH62T version 5 canceled Jubba Cloak: Slip Tip stayed held, the Nexus stayed spent, and continuing the original storm removed four CHOAM and three opposing forces. No phone overflow or page errors were observed. /tmp/dune-choam-restore.cjs performs read-only private restoration checks.

The opening backup and final comparison at that checkpoint preserved all 3,484 older room versions and state hashes. Only two browser rooms and thirty HTTP-test rooms were added, for 3,516 total. The existing server was reused; no hourly restart was due. Automation remained removed. Those historical checks did not certify a complete six-effect CHOAM advantage or full module play, and the later new-profile contract does not expand their evidence.
