After legal placement, a living native Sandmaster may take one board spice from the single destination pile before faction arrival reactions. A ride has no intermediate ground route and never consumes normal movement. Multiple source sectors and typed elite forces earn one collection total. Each separate ride has its own opportunity. Decline and legacy actions retain ordinary riding; empty/ambiguous piles and unsupported module combinations suppress collection without preventing the ride. Share the public quote across server, destination checkbox and existing bot candidates. AI only gains minimal legal participation: no new destination policy or strength calibration. Keep base factions plus Leader Skills as the bounded scope; other expansion rosters/modules, Ecaz treachery and multiple positive piles remain guarded. Record the composition of printed worm-movement wording with the existing Sandmaster contract, including the existing per-distinct-movement inference. No combined-effect FAQ or complete module compliance is claimed. The room's atomic versioned write settles the physical transfer once before a pending Bene Gesserit reaction. Saved continuation resumes only the arrival and remaining ride queue. Ten new engine, control and SQLite cases cover Basic/Advanced custody, opt-out, legacy fields, rejected-action immutability, trainer visibility/control, public mode guards, private views, simultaneous duplicates, restarted arrivals, distinct queued rides and a genuine special-Karama worm through Nexus. Correct the shared shipment fixture to retain each faction's actual elite total and support Bene Gesserit as the opponent. Independent source and implementation review found no material defects. Focused work found and fixed the generic decision handler clearing the decision before the new quote, plus test-only fixture/type issues. Types, lint, 4894 offline tests, production build and 43 HTTP tests passed on unchanged source. Two genuine four-profile Leader Skills samples finished in 265 Basic and 211 Advanced actions, no rejected candidates, and 14 JSON restorations. Neither naturally encountered the new effect; targeted checks establish it. This is playability evidence, not AI calibration. Isolated browser room RMMA6LEF used a normally created Fremen seat and a conserved staged Advanced Leader Skills position. Selected two forces from each of two sectors, including one elite each, toggled collection off and on, then rode to Red Chasm. The UI showed four arrived forces and balance six before the opponent reaction. Refresh preserved that pending decision, balance and explanatory once-only collection history. The opponent's production-engine arrival response resumed to CHOAM charity; another refresh retained six spice and the private Chani traitor. Seat rows were unchanged. This is a targeted staged browser journey; screenshot and complete human-game acceptance remain open. All 1140 original rooms, 2385 seats and every original recovery, entry and handover row remain unchanged. HTTP/browser checks added 34 rooms and 71 seats. SQLite integrity and foreign keys pass. No restart, reset, migration, maintenance automation or usage check was needed. No mode or publication gate is opened.

Dune — Arrakis Table
An unofficial multiplayer adaptation of Gale Force Nine’s classic 2019 Dune, built with React, TypeScript, Vinext, and Cloudflare Workers/D1. Development is ongoing; this is not yet a complete rules implementation. Advanced and unfinished expansion starts remain disabled. Start with current status for implemented systems, remaining requirements and release gates; detailed historical evidence remains in the implementation log.
Run locally
Use Node.js 22.13 or newer and npm. Install the locked dependencies and apply local migrations before starting the server:
npm ci
npm run db:local
npm run dev -- --host 0.0.0.0
Open http://localhost:3000. Create a room, share its eight-character invitation, and add human or AI seats. The host can configure Easy, Medium, Hard and Brutal AI opponents. Current calibration demonstrates a substantially weaker Easy policy; it does not yet demonstrate a consistent ordering among the upper three levels.
Full AI implementation and tuning wait until all non-AI game features are complete. The AI development plan then targets approximately 75% higher-tier wins for Medium/Easy, Hard/Medium and Brutal/Hard. Until that stage, AI work focuses on minimal legal participation and critical playability fixes.
Choose Learn to play for the interactive introduction
at /learn. Practice shipping, battle plans and collection before entering a
room; lesson progress stays in your browser and does not change saved games.
Local games persist in .wrangler/state. Keep this directory across restarts. Apply new additive migrations before running code that depends on them. Never delete the local database to resolve a connection or rules problem. .openai/hosting.json belongs to the existing Sites project; do not recreate the hosting project.
Saved seats and reconnecting
The room cookie identifies your seat. Refreshing or reopening the invitation with that cookie restores your private hand and pending decisions. A failed restoration offers an explicit retry. Requests time out after 15 seconds; uncertain game actions are reconciled with a read rather than automatically repeated.
Use Protect your saved seat to generate and privately save a recovery kit before enabling its key. Keep the complete kit separate from the invitation. Recover a saved seat uses that kit to restore the same faction after cookie loss and revokes the previous browser sessions for that seat. Recovery keeps existing forces, resources and sealed commitments. Anyone holding the kit can control that seat and see its private information.
If recovery receives no confirmed response, keep the page open and retry the same recovery request. The server recognizes the receipt and does not rotate twice. Replacing the recovery key invalidates the older kit. Host-initiated takeover remains unfinished. An owning human seat can enable or disable its own AI control during a started game.
New create/join requests save a private, tab-scoped retry record before sending. If the response is uncertain, keep the tab open and use the explicit retry; refresh preserves the same request. Confirmed success removes that record. Clearly rejected first requests return to the form for correction. A retry can recover the original room and seat without creating duplicates, but closing the tab or clearing its data can lose the proof. This record is separate from the long-term seat recovery kit.
An uncertain saved-kit recovery keeps its exact retry details in memory and prevents conflicting navigation. If that recovery has become obsolete, deliberate abandonment releases the controls after explaining that it cannot undo a completed recovery. Keep a valid saved kit before discarding retry details.
Use Pass your seat to another player for a voluntary one-time transfer. The private offer lasts 24 hours; acceptance preserves progress and revokes the old owner’s sessions and recovery kits. The recipient uses Accept a seat handover on the home page, then creates their own recovery kit. Keep the tab open until acceptance is confirmed; exact private retry details survive refresh in that tab. See seat handover for cancellation, retry behavior and current limits.
The table header offers optional Sound effects, with mute, volume and a test sample. Short cues mark phase changes and automatic action notices. Sound starts off; preferences stay in your browser. See table sounds for activation, background behavior and prototype limits.
Verify changes
Use the development guide for architecture, focused tests and the repeatable verification tools. Tests are discovered automatically; the default suite includes in-memory persistence recovery and needs no server:
npm test -- ecaz-collection ecaz-spice
npm run check
npm run build
Run npm run test:integration against a development server for HTTP/session
changes. npm run test:multiplayer remains available for recovery plus HTTP
checks; npm run test:recovery runs only in-memory persistence tests. All test
commands accept filename fragments and --list after --.
The production build is written to dist. npm start runs that build with Wrangler; apply its database migrations to the intended storage environment before use. The included local migration command targets the development database, not a remote deployment.
Reproduce the current AI study with:
node --import tsx tools/ai-calibration.ts --games 120 --seed 20260907 --out /tmp/dune-ai-calibration.json
See AI calibration, multiplayer audit, component inventory, and visual playtest for scope and limitations. Passing subsystem tests does not certify every rules combination.
Development maintenance
The user-authorized 13 September 2026 local reset established a fresh saved-game baseline; see the reset record. Preserve all games created after that checkpoint.
Reuse the running development server. Restart only when a code or configuration change, or an observed server condition, makes leaving it running likely to cause issues; use judgment rather than an hourly schedule. Preserve database state, warn before interrupting human play, and defer until a safe decision point. Verify server health and restoration after a necessary restart. No recurring automation is installed; the user requested leaving it removed. Fix causes of crashes and lost progress rather than relying on restarts.
The application bundles its artwork, fonts and rules guidance. Source provenance and third-party notices live in developer documentation; the player-facing reference uses internal links. Publication remains gated on completion and integrated verification of the requested rules, expansions and critical player journeys.
