New players can open Learn to play from the lobby or rules reference. Five lessons explain public/private information and turn phases, then offer three independent exercises for ordinary shipment budgets, a sealed battle plan and spice collection, followed by joining and recovering a real table. Shipping, combat and collection use existing production quotes rather than a separate simplified calculator. The fixed opposing plan is a teaching example, not an AI match. Reuse the battle wheel and card inspectors, provide keyboard inputs, move focus to the current lesson heading and stack the layout on phones. Versioned browser-local choices preserve lesson position, shipment, defense/dial and reveal state. Whitelisted validation rejects corrupt saves and impossible committed shipments. SSR uses a stable hydration placeholder before reading browser storage; direct user handlers save choices and retain usable in-memory state on storage failure. No room, seat credential or multiplayer API is used. Six new tests cover prices and affordability, every offered battle dial/defense, protected ties, weapon death, actual losses/bounty, collection limits and city capacity, saved-choice validation and internal rule links. Types, lint, 4872 offline tests and production build pass on the unchanged source fingerprint below. The first required check stopped on React setState-in-effect and semantic-status lint findings; these were fixed before the successful complete run. Independent review found no material defect in the examples or final hydration/save implementation. Browser controls verified an unaffordable shipment, legal six-force shipment, card inspection, protected 8-8 aggressor victory, Snooper/projectile death and bounty, sealed refresh, city collection, lobby return/re-entry and newly changed choices after the hydration correction. At 390px the battle controls and lobby Learn link stayed within page bounds; the viewport override was reset. Screenshot capture timed out, so visual screenshot acceptance is still open. Storage-denial browser testing and the broader faction, movement, bidding, alliance, Advanced and expansion curriculum remain unfinished. All 1106 current rooms, 2314 seats and all original recovery/entry/handover rows exactly match the fresh outage backup. SQLite integrity and foreign-key checks pass. The healthy server was reused; no restart, database migration/reset or maintenance automation was needed. HTTP integration and full-game samples were not rerun for this isolated teaching surface; server game behavior did not change. A bounded independent primary-source review supports Smuggler's reveal-bound deferred survival receipt but found no exact ruling for modified leader strength. Record the one new user question and preserve the unanswered gate; lower collection remains missing. This does not enable any rules mode, expansion or publication gate.

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.
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.
