-## Layout
+## Workspace
-- The repo is `server/` in the `MoonMiners/` workspace; agent worktrees go next to it
+- The repo is `game/` in the `MoonMiners/` workspace. Design notes live in the workspace,
-  (`git worktree add ../wt-<task> -b <task>`), a Defold client later in `../client`.
+  outside git (`../project.todo`, `../FAQ.org`, `../druid-notes.md`).
-- `main.go`: commands (`serve`, `migrate`, `load-config`, `sim [file]`, `moon-traits`), `.env`
+- Agent worktrees go in the workspace, next to `game/`. Make them with `scripts/wt` (from
-  loading. `balance.go`: the `sim` command (prints the `sim.go` analysis).
+  the workspace: `game/scripts/wt up <task>`), not by hand: it makes `../wt-<task>` on

+  also removes the worktree (and the branch if merged). State in `<worktree>/.wt/`.
-- `views.go`: the `View` (section, moon, well, tab; carried in the URL as

+  commit it.
-  models mapped to JSON DTOs; times in unix ms) and `POST /api/act/<action>` (same
-  `runAction` as `/act/`, gates included; `{ok, error, toast, fx, state}`, rule errors 422).
-  Player id from `X-MM-User` or the cookie, else a new player (id echoed back).
-  `api_sections.go`: every section's block (equipment and drill panel, store, refinery,
-  advisors, leaderboard, help, new-moon teaser, reveal and buy modal in act responses, moon
-  sale, market chart), plus `rules` (numbers for client prediction), `catalog` (static data,
-  image URLs, tool codes), `jobs`, `bonuses`, `liveEvents`; blocks come with `s=` or
-  `include=`; reasons are codes with the web's text beside them (`whyText`, …), confirm dialogs as `confirm`; `catalog=0` or `catalog=<catalogVersion>` skips the catalog; `clientSeq` is echoed. A new section in the API:
-  map its view model in `addSection`. `api_test.go` (in `make check`) builds every block
-  for every test view.
-- `config/game.json`: the game config (starting credits/resources/tools, moon price, well
-  supply, `wellCountWeights`, resource prices, store items with upgrade tiers, moon types: a
-  name, a placeholder description and resource `affinities`, refinery), embedded.
-  `rollWells` (game.go) rolls a new moon's wells: 2–5 by weight, resources by its type's
-  affinities, each well's supply rolled in [`wellSupplyMin`, `wellSupplyMax`) (fewer wells
-  hold less); a first moon
-  always has every raw input of a recipe. A moon's name comes from `moonNames` (roots and
-  suffix style weights, `rollMoonName`), never repeated among a player's moons; its type is
-  `staking_source.kind` (moons from before migration 013 were named after their type).
-  `config.go` parses it into `game` and syncs store items into `store_item`/`upgrade_item`
-  (needed for the inventory foreign key and the SQL in game.go). Admins override its
-  values live on `/utils/economy` (table editor in `economy.js`; `economy.go`: a patch per
-  save in `config_override`, latest wins; `sim.go`: balance analysis and progression sim). Read config values through
-  `cfg()` (game.json + override), never `game` directly. `migrate.go`: database setup.
-- `db.go`: connections, `inTx`, `GameError`.
-- `market.go`: market prices. A unit sells for its config price × a deterministic drift
-  (name + 5-minute tick, within ±`marketVolatility`) × live price events × the player's
-  selling pressure (`marketPressure`: their recent sales of the item, in base-price credits,
-  decaying with a half-life, table `market_pressure`; the factor eases from 1 towards
-  `floor`, and a sale is priced at its average over the pressure it adds). `marketRate` is
-  used by `sell`/`sellRefined` and the market view (24h history recomputed, no table);
-  view model for the Market section (ticker, watchlist, chart, sell ticket; `pick=` in the
-  URL selects a quote). `web/static/js/market.js`: chart crosshair and ticket estimate.
-- `resale.go`: selling a moon back (`moonResale` in game.json): what's left in its wells at
-  market price (with live events, without selling pressure or advisors) × `factor`, capped
-  at `maxRatio` × the replacement moon's price (`moonPriceFor(owned-1)`), which it's
-  compared with. Not the last moon, not within `minHoldSecs` of buying it, not while a
-  drill on it is running; finished drills are claimed in the sale. Template: `moon-sale`.
-  Also selling tools and spare attachments for `equipmentResale.factor` (below 1) of their
-  credit price (a tool: price + its upgrades; refined parts not refunded): only idle
-  tools with nothing to claim, never the last tool; attachments on it return to the inventory.
-- `refinery.go`: refinery config (`refinery` in game.json, `parts` on upgrade tiers), rules
-  (start batch, collect, buy slot, sell refined, upgrade parts) and its view model. A batch
-  of n takes `seconds` × n^`bulkExponent` (`batchSecs`). Tables
-  `refined_account`, `refinery_job`, `users.refinery_slots`. Template: `refinery.html`.
-- `bonus.go`: player bonuses. `bonusesFor` combines advisors and a tool's attachments
-  (multipliers multiply, then each kind is capped by `bonusCaps`); live events multiply on
-  top, uncapped. `drillStats` turns a tool's cycle and yield into a stake's (used by
-  `stakeInTx`, the views and the sim); sells and refinery batches use `Bonus.Sell`/`Refine`.
-  Bonuses are fixed when the action runs (a stake keeps its duration and amount).
-- `attachments.go`: attachments config (`attachments` in game.json: `slotsPerTool`, items
-  with `speed`/`yield` multipliers), buy/equip/unequip rules (one of each per tool; equip
-  and unequip any time, they count from the next stake), store cards and the drill panel
-  (`drill=` in the URL, Equipment section, in the aside). Table `attachment`
-  (`inventory_item_id` null: unequipped).
-- `advisors.go`, `web/templates/advisors.html`: advisors config (`advisors`), hire and buy
-  seat rules, Advisors section. Tables `advisor_hire`, `users.advisor_seats`.
-- `onboarding.go`: onboarding by progressive reveal, no tutorial text. `users.onboarding`
-  holds flags that are only ever added (gates passed, `claimed:<resource>`, `seen:<tab>`,
-  `all` for players from before it). New players see only the first moon purchase; deploying
-  reveals Equipment, claiming Market, selling Store (and "+ New moon", Help, upgrades,
-  attachments, moon sale, Redrill), claiming both raw inputs of a recipe Refinery, buying a
-  tool or attachment Advisors. Templates ask `.S.Unlocked "<feature>"`; `View.resolve` sends
-  locked sections to the moon view and `runAction` refuses locked actions (`actionGates`).
-  A revealed tab shines (`data-shine`) until opened (`markSeen` in `handleIndex`). New
-  sections and actions need a gate there.
-- `players.go`, `web/templates/players.html`: admin Players page at `/utils/players`
-  (search, detail, grants, finish drills, reset, onboarding reset/unlock all, ban; each logged as `admin_*` in
-  `event_log`). `notBanned` gives banned players (`users.banned_at`) a suspended page.
-  `web/templates/admin.html`: the shared admin nav (`{{template "admin-nav" "<page>"}}`, put
-  it on every `/utils` page) and confirm dialog. `/utils` redirects to `/utils/players`.
-- `web/templates/`: `page.html` (page shell, boot page), `app.html` (header, moon
-  list, sections, side panel).
-- `web/static/js/main.js`: glue between htmx and the scene (and what a morph keeps of the JS's
-  own changes: classes, styles, inserted elements, typed values), and countdowns (`data-ends`)
-  that enable their Claim button (`data-ready-at`) when due. `scene.js`: the three.js scene.
-  `tabs.js`: sliding tab highlight (`data-tabs`). `enter.js`: entrance animations on view
-  changes. `ui.js`: the custom confirm dialog (`hx-confirm`) and toasts, shared by the game
-  and admin pages.
-- `web/static/js/fx.js`: effects per action result (toast `data-fx`). `sfx.js`: sound
-  (Web Audio; clips in `web/static/assets/sfx`, see CREDITS.txt; synth sounds via vendored
-  ZzFX). fx.js maps action kinds to sounds; mute is in the header, `window.mmAudio` for
-  outside control (e.g. ads).
-  `terrain.js`: moon generation (no imports, also runs in the worker). `moons-admin.js` and
-  `web/templates/moons.html`: the moon lab. `moons.go`: moon settings endpoints, `isAdmin`.
-  `moondesc.go`: moon descriptions generated from the look (mirrors terrain.js `moonTraits`;
-  `scripts/check-moon-traits.mjs` in `make check` keeps them in sync) and the wells.
-- `reveal.go`, `web/static/js/reveal.js`: the new-moon section (`s=new-moon`, a teaser with a
-  shrouded moon in the viewport, `mystery` in the scene data) and the reveal after
-  `buy-moon` (the response carries `#reveal` with the moon's card; scene.js plays the
-  burst, fx.js waits for `mm:revealed` before counting the balance down).
-  `rating.go`: a new moon's rating, the percentile of its base-price value among a cached
-  sample of `rollWells` (resampled when the config changes), stored in
-  `staking_source.rating`; tiers Poor/Fair/Good/Great/Exceptional drive the card's verdict
-  and the star chip in the moon list and header.
-- `liveops.go`, `events.go`, `web/templates/liveops.html`, `web/static/js/liveops.js`: live
-  ops at `/utils/liveops` (dashboard from `event_log`, timed events in `live_event` applied
-  via `eventMultiplier` in game.go, `announcement`; both shown in the game's `#banner`).
-- `scripts/tool-art.mjs`: draws the tool images (`web/static/assets/items`, one per tool and
-  tier: `<image>-tN`, `StoreItem.ImageAt`); rerun it after adding a tool or tier (needs
-  rsvg-convert and ImageMagick). A new tool needs a drawing there.
-- `web/css/app.css`: Tailwind input (custom HUD styles); builds to `web/static/css/app.css`.
-- `sql/tables.sql`, `sql/data.sql`: schema for fresh databases. `sql/migrations/` (001–015):
-  changes for existing ones, applied on every `migrate`, so each must be idempotent.
-- `test-endpoints.restclient`: the up-to-date list of endpoints, in Emacs restclient format.
 
-## Commands
+## Conventions (all parts)
-- `make dev`: server on :3000 that reloads templates/static from disk, with Tailwind watching.
+- The server is the authority: clients show the state it sends and send actions; no game
-- `make build`, `make check` (gofmt, vet, template check, JS syntax of every `web/static/js/*.js`,
+  rules on the client side beyond what `server/api.md` "Prediction" allows.
-  moon traits check), `make migrate`, `make load-config`. `go run . sim` prints the economy analysis.
+- Work in one part at a time: a client task doesn't change `server/`, and the other way
-- Template check: `templates_test.go` (`go test -run Templates`, in `make check`) parses the
+  round, unless the task says so.
-  templates like the server and renders every page and region against in-memory game states;
-  when you add a page, section or view model branch, make sure its states/views reach it.
-- Local DB: `podman-compose up -d db` then `make migrate` (see README).
-There is no other test suite, except `wells_test.go` (`go test -run Wells -v`: well roll
-distribution, value by well count, resale odds, sim seeds).
-
-## Deployment
-- Production uses `docker-compose.prod.yml` (deployed with Dokploy): `app`, `db` (stock
-  Postgres) and `migrate` (same image as `app`, runs on every deploy before the app starts).
-- Schema changes need both an update to `sql/tables.sql` (fresh DBs) and a new idempotent
-  `sql/migrations/NNN-name.sql` (existing DBs). Check that a fresh DB and one built from the
-  pre-Go schema (`git show 610d26e:sql/tables.sql`) plus all migrations give the same
-  `pg_dump --schema-only`.
-- Keep `docker-compose.prod.yml` services on the explicit `internal` network (Dokploy adds its own network).
-
-## Environment
-Postgres credentials come from `.env`: `DB_USER`, `DB_PASSWORD`, `DB_HOST`, `DB_PORT`,
-`DB_DATABASE`, plus `ADMIN_DB_USER`/`ADMIN_DB_PASSWORD` for `migrate`. Never read, print or
-commit `.env`. `ADMIN_USER_IDS` (comma-separated player ids) grants access to `/utils`
-(unset: nobody); with `MM_DEV=1` everyone is an admin.
-
-## Conventions
-- Game rules go in `game.go`, in a transaction, locking what they read. Keep handlers thin.
-- Layout: header, moon list, main area (one section at a time), and an aside with the 3D
-  viewport and the selected well. Links are `<a href hx-get>` to a view URL; main.js keeps
-  the address bar in sync.
-- New section: add it to `sections` and `State.page` (views.go) and a `<name>-section`
-  template in `app.html`. New action: a case in `server.runAction` (shared by `/act/` and
-  `/api/act/`) plus a button with `hx-post="/act/<action>"`. The current view (s, moon, well, drill) is sent automatically,
-  so action parameters must use other names. Give it a sound in fx.js if it needs one.
-- Clicks give instant feedback only (busy state + spinner). No client-side game logic or
-  prediction; the server is the authority. Pages don't reload on timers: countdown labels
-  (`data-ends`) tick client-side and may enable a Claim button, as display only.
-- SQL is lowercase with snake_case identifiers.
-- When you add an endpoint, add it to `test-endpoints.restclient`.
-- New player action: log it with `logEvent(ctx, tx, userID, "<kind>", data)` inside its
-  transaction (spends use the key `price`, earnings `credits`; the dashboard sums them).
-- Dispose any three.js geometry and materials you create.
 - Keep changes small. Don't refactor or move files unless asked.

-upgrade mining tools, stake them on wells, claim resources when the stake completes, and sell
-resources for credits (₥). Drill cycles last seconds, so play is active. The refinery turns
-resources into refined items on a timer; those sell for more and are needed as parts for
-higher tool upgrades.

-a three.js view of the selected moon, generated procedurally from its id. Game rules run in
+- `client/`: Defold client, for desktop and the browser (WebAssembly).
-Go, one Postgres transaction per action. The page doesn't reload on timers: countdowns tick
-in the browser and enable each Claim button when its drill should be done, and the server
-decides what is actually ready when it's clicked.
 
-Players join anonymously: on the first visit the server creates a player and stores its id in

-## Requirements
+Needs Go 1.25+ and Podman or Docker. Put a `.env` in the repo root (variables in
+`server/README.md`).
 
-- Go 1.25+
+```bash
-- PostgreSQL 16 (stock image is fine), or Podman/Docker to run it
+podman-compose up -d db        # or: docker compose up -d db
-- Node.js, only for `make check` (syntax-checks the JS)

-`make` downloads the Tailwind standalone CLI into `bin/` on first use.
+make dev                       # http://localhost:3000: the game (once built, below); /utils: the admin
-
-## Environment
-
-The server reads `.env` in the project root (gitignored, never commit it). Real environment
-variables take precedence.
-
-```dotenv
-DB_USER=moonminers         # app user: read/write access to the tables
-DB_PASSWORD=moonminers
-DB_HOST=localhost
-DB_PORT=5432
-DB_DATABASE=moonminers
-ADMIN_DB_USER=postgres     # superuser, only used by `migrate`
-ADMIN_DB_PASSWORD=postgres
 ```
 
-Optional: `PORT` (default 3000), `DB_SSLMODE` (default `disable`), `MM_DEV=1` (reload templates
+After pulling changes or editing `server/config/game.json`, run `make migrate` again before
-and static files from disk; also makes everyone an admin), `ADMIN_USER_IDS` (comma-separated
+starting the server: it applies new migrations and syncs the tools and prices with the
-player ids allowed on the admin pages; unset means no admins), `TRUST_PROXY=1` (behind a reverse proxy: rate-limit new
+config (the server alone doesn't).
-players by the last `X-Forwarded-For` address instead of the connection's; new players are
-limited to 10 a minute per IP).
 
-## Local development
+## Defold client
 
-1. Create `.env` as above.
+Needs the Defold editor (https://defold.com/download/) or Java 21+. The Makefile downloads
-2. Start Postgres and set up the database (roles, schema, migrations, store items from
+Defold's command-line builder (`bob.jar`) and runs it with the Java the editor ships, found
-   `config/game.json`):
+in the usual places on Linux, macOS and Windows (`make DEFOLD=<folder holding its packages>`
+for another place, `JAVA=<path>` for your own Java); without an editor, `java` from PATH.
 
-   ```bash
+```bash
-   podman-compose up -d db     # or: docker compose up -d db

-   make migrate
+make run                       # desktop build, plays against http://localhost:3000
-   ```
+make web                       # browser build into dist/web/MoonMiners/

-3. Run the server and open http://localhost:3000:
+The server serves the browser build at http://localhost:3000 (from
+`client/dist/web/MoonMiners`, or `MM_WEB_DIR`). It looks for the build when it starts:
+after the first `make web`, restart the server; later builds only need a page reload.
+Without a build, `/` goes to the admin. The desktop and browser games keep separate saved
+players.
 
-   ```bash
+## Deploy
-   make dev

-   Template, CSS and JS changes show up on reload; Go changes need a restart.

-`terrain.js` agree on moon looks), `make load-config` (sync the store items in the database with `config/game.json`).
-
-The binary's commands: `serve` (default), `migrate`, `load-config`, `sim [file]` (print the
-economy analysis and a 4-hour greedy-player sim for the game config, or for a config file),
-and `moon-traits` (JSON on stdin; used by the moon traits check).
-Reset the local database: `podman-compose down -v && podman-compose up -d db && make migrate`.
-
-## Database changes
-
-`migrate` runs on every deploy and must be safe to repeat. It creates the `devs` role and the
-app user, creates the schema from `sql/tables.sql` and `sql/data.sql` on an empty database,
-applies `sql/migrations/*.sql` in name order, grants the app user access, and syncs the
-store items with the game config.
-
-For a schema change, update `sql/tables.sql` (fresh databases) and add an idempotent
-`sql/migrations/NNN-name.sql` (existing databases: `if not exists`, `if exists`). A fresh
-database and one migrated from the pre-Go schema through every migration must end up with the
-same schema (compare `pg_dump --schema-only`). The migrations so far: 001 drops the old config
-tables, 002 moon settings, 003 config overrides, 004 live ops, 005 refinery, 006 player
-admin, 007 drill cycles in seconds, 008 security fixes (UTC defaults, one claim per stake,
-non-negative well supply), 009 schema cleanup (old columns, moon images), 010 drill
-attachments and advisors, 011 market pressure, 012 onboarding, 013 moon type
-(`staking_source.kind`, now that moons get generated names).
-
-## Game config
-
-`config/game.json` holds the balance numbers (starting credits, resources and tools, moon
-price, well supply range, `wellCountWeights`: how many wells a new moon gets, resource prices
-in credits per unit), the store items with their
-upgrade tiers (tiers can also need refined `parts`; a drill cycle is `completionTimeInSecs`),
-the moon types (a name, a placeholder description: the look is procedural and the
-description is generated when the moon is bought, see `moondesc.go`, and `affinities`:
-weights of the resources its wells hold, 1 if unlisted), moon names (`moonNames`: roots, and
-weights for the suffix styles: Roman numeral, Greek letter, catalogue number, letter and
-number; a player never gets the same name twice), and the refinery
-(`refinery`: slot prices, max batch size, `bulkExponent` (a batch of n takes
-seconds × n^bulkExponent, so bigger batches are faster per unit), and the refined items with
-their recipe, seconds per unit and sell price). Market prices move: every 5 minutes each resource and refined item
-drifts within ±`marketVolatility` (default 15%) of its configured price, from a deterministic
-function of name and time (`market.go`), which also gives the 24h charts; sells use it.
-A player's own selling lowers their price a little (`marketPressure`): each sale adds its
-base value to their pressure on the item, which halves every `halfLifeSecs`, and the price
-factor is `floor + (1 − floor) × e^(−pressure / scale)`, so it flattens out at `floor`.
-Drill attachments (`attachments`: `slotsPerTool`, and per attachment a `price`, an `image`
-and `speed`/`yield` multipliers) are bought in the Store and equipped on a drill from its
-panel in Equipment, where idle drills and spare attachments can also be sold back for
-`equipmentResale.factor` of their credit price (a drill: its price plus its upgrades; refined
-parts aren't refunded). A moon sells back (`moonResale`) for what's left in its wells at market
-price × `factor`, at most `maxRatio` × the price of a replacement moon, no sooner than
-`minHoldSecs` after buying it, and not while a drill on it is running. Advisors (`advisors`: `seatPrices` for the 2nd, 3rd, ... seat, and per
-advisor a hire `price` and `speed`/`yield`/`sell`/`refine` multipliers) boost the whole
-account. A player's multipliers multiply together and each kind is capped by `bonusCaps`;
-live events multiply on top. They count when an action runs, so a stake keeps the bonuses
-it started with (`bonus.go`).
-It's embedded in the binary, so changes need a rebuild.
-Store items are also kept in the database (`migrate` and `make load-config` sync them;
-items removed from the file are deleted unless a player owns one).
-
-Admins can change these numbers without a deploy on `/utils/economy` (see Admin panels).
-
-## Admin panels
-
-Admins are the player ids listed in `ADMIN_USER_IDS` (comma-separated). With `MM_DEV=1`
-everyone is an admin, so never set it in production. Other players get a 403 (the admin pages
-show "missing permission"). Every admin page
-shares one nav: Players · Moons · Economy · Live ops · Game.
-
-| Page | What it's for |
-|---|---|
-| `/utils` | Redirects to `/utils/players`. |
-| `/utils/players` | Find players (id prefix or name), sort by last seen, activity, newest, richest. |
-| `/utils/players/{id}` | One player: balance, resources, refined items, moons and wells, tools and drills, event history (older pages at `/utils/players/{id}/events?page=n`). Grant/remove credits, grant resources and tools, finish running drills, reset, ban/unban. |
-| `/utils/moons` | Moon lab: live 3D preview with sliders for terrain, craters, colors, bloom, atmosphere and rotation. "Save for the game" applies the look to every moon. |
-| `/utils/economy` | Edit the game config without a deploy: tables for equipment (with upgrade tiers), resources, refined items, market, attachments, advisors, moon types and constants, saved together as a draft; live analysis of the draft, version history with revert/reset, raw JSON. |
-| `/utils/liveops` | Dashboard, timed events and announcements. |
-
-Actions (all `POST`, confirmed in the page's own dialog):
-
-| Endpoint | Actions |
-|---|---|
-| `/utils/players/{id}/{action}` | `credits`, `resources`, `tool`, `finish-stakes`, `reset`, `ban`, `unban` |
-| `/utils/economy/{action}` | `analyze`, `save`, `revert`, `reset` |
-| `/utils/liveops/{what}` | `events/save`, `announcements/save` |
-| `/utils/liveops/{what}/{id}/{action}` | toggle or delete an event, delete an announcement |
-| `/utils/{action}` | `clear-data`, `load-config` (older endpoints, no page) |
-| `/api/moon-settings` | `GET` (public) returns the saved moon look; `POST` (admins) saves it |
-
-Request examples are in `test-endpoints.restclient`.
-
-### Players
-
-Every admin action is logged in `event_log` with the admin's id (`admin_*` kinds, which the
-live-ops stats ignore). Banned players see "This account is suspended" and their actions get a
-403.
-
-### Moons
-
-Each moon's look is generated from its id (terrain technique, noise, craters, colors). The lab
-edits the shared settings that every moon starts from; they're stored as one JSON row in
-`moon_settings` and merged over the defaults in `web/static/js/terrain.js`.
-
-### Economy
-
-A form for the constants, resource prices, store items and upgrade tiers (including parts),
-and the refinery, plus a raw JSON editor for every field. The analysis updates as you type:
-income and payback per tool and upgrade, refining gain per recipe, red flags, and a 72-hour
-greedy-player sim. Each save stores the values that differ from `config/game.json` as a new row
-in `config_override`; the latest row is in effect (merged over the file, reloaded every 30 s)
-and store items are re-synced.
-
-### Live ops
-
-- Dashboard: players, daily actives, D1/D7 retention, actions, credits earned vs spent,
-  resources claimed. Built from `event_log`, which every game action writes to.
-- Timed events: yield, sell price or mining speed multipliers, applied server-side.
-- Announcements.
-
-Live events and announcements show in a banner at the top of the game. Times are UTC.
-
-## Interface
-
-Server-rendered regions swapped by htmx, which morphs them into the page with the idiomorph
-extension (0BSD, `web/static/vendor/idiomorph`) so elements keep their state; the JS only
-adds display: `main.js` (htmx glue,
-viewport, countdowns), `fx.js` (effects per action result), `sfx.js` (sound, below),
-`tabs.js` (sliding tab highlight), `enter.js` (entrance animations when a view changes),
-`market.js` (chart crosshair), `ui.js` (confirm dialog and toasts, shared with the admin
-pages), `scene.js`/`terrain.js`/`moon-worker.js` (the moon).
-
-## Sound
-
-`web/static/js/sfx.js` plays sound effects with the Web Audio API: short clips from Kenney's
-CC0 packs (trimmed and loudness-matched, listed in `web/static/assets/sfx/CREDITS.txt`) and
-a few sounds synthesized with ZzFX (MIT, `web/static/vendor/zzfx`). The speaker button in the
-header mutes them (remembered per browser); they are also muted while the tab is hidden.
-`window.mmAudio.mute()` / `unmute()` mute from outside (e.g. during an ad) without touching
-the player's setting. Set `localStorage["mm-sfx-debug"] = "1"` to log every sound played.
-
-## Security
-
-- Players are identified only by the `mm_user` cookie (HttpOnly, SameSite=Lax). New players
-  are rate-limited to 10 a minute per IP (`TRUST_PROXY=1` behind a proxy).
-- Request bodies are capped at 64 KB (1 MB for `/utils/economy/*`); forms are parsed up front,
-  so oversized ones get a 413.
-- Every response sets `X-Content-Type-Options: nosniff` and `Referrer-Policy: same-origin`.
-- Game actions validate ids, lock what they read and keep balances and supplies at 0 or more
-  (schema checks back this up); a stake is claimed at most once (unique index).
-- Errors that aren't rule violations are logged and answered with a generic 500.
-
-## Deployment (Dokploy)
-
-`docker-compose.prod.yml` runs `db` (Postgres 16, data in the `db-data` volume), `migrate`
-(schema and migrations, runs before the app on every deploy) and `app` (port 3000).
-
-First deploy:
-
-1. Dokploy: create a **Docker Compose** service from this repository, compose path
-   `docker-compose.prod.yml`.
-2. **Environment**:
-
-   ```dotenv
-   POSTGRES_PASSWORD=...   # strong; Postgres superuser, used by migrate
-   DB_PASSWORD=...         # strong; app user "moonminers"
-   ADMIN_USER_IDS=         # fill in at step 5
-   ```
-
-   Never set `MM_DEV` in production: it makes every player an admin.
-3. **Domains**: your domain → service `app`, port `3000`, HTTPS on.
-4. Coming from the old (Next.js) version and want a clean start? Stop the service and delete
-   the `db-data` volume first. Otherwise `migrate` upgrades the old database in place.
-5. Deploy, open the site once, and copy your player id: the value of the `mm_user` cookie
-   (browser dev tools → Storage/Application → Cookies). Put it in `ADMIN_USER_IDS`
-   (comma-separate several) and redeploy. The admin pages are at `/utils`.
-
-Updates: push to the branch Dokploy tracks and deploy; `migrate` applies new migrations.
-Back up `db-data` with `pg_dump` or Dokploy's volume backups.
-
-To test the production stack locally:
-`POSTGRES_PASSWORD=x DB_PASSWORD=y podman-compose -p mmprod -f docker-compose.prod.yml up --build`
-(add a `ports: ["3100:3000"]` override for `app` to reach it).
-
-## Endpoints
-
-See `test-endpoints.restclient` (Emacs restclient format).

-# Moon Miners JSON API
-
-For game clients other than the htmx page (the Defold client). Same state and rules as the
-web game: `GET /api/state` is built from the same view models as `GET /`, and
-`POST /api/act/<action>` runs the same code as `POST /act/<action>` (`runAction` in
-server.go), onboarding gates included. Code: `api.go`.
-
-Conventions:
-- Times are unix milliseconds (`null` when unset), durations seconds. `state.now` is the
-  server's clock: compute time left as `end - now` (plus the time since the response).
-- Amounts and prices are raw numbers; the client formats them (currency symbol ₥, see
-  [Texts](#texts) for the web's formats).
-- Reasons are codes, each with the web's player-facing text next to it (`why` and
-  `whyText`, `noSale` and `noSaleText`, …), and actions the web confirms carry the dialog's
-  words (`confirm`, see [Texts](#texts)). Other display text: names, descriptions, toast
-  messages, banner text and the few labels listed with their fields.
-
-## Auth
-
-The player id is read from the `X-MM-User` header, else the `mm_user` cookie. If neither
-names an existing player, a new one is created (at most 10 per minute per IP, else
-`429`), with `newPlayer: true` in the body. Every successful response returns the id in
-the `X-MM-User` header, the `mm_user` cookie and `userId`; store it and send it back.
-Banned players get `403`.
-
-## GET /api/state
-
-Query params (all optional, same as the web URL): `s` (section: `moons`, `equipment`,
-`market`, `store`, `refinery`, `advisors`, `leaderboard`, `help`, `new-moon`), `moon`,
-`well`, `list=past` (show a mined-out moon), `pick` (market: selected quote), `drill`.
-`include` (comma-separated sections, or `all`): section blocks to add besides the one for
-`s` (see [Sections](#sections)); locked ones are skipped. Invalid or locked values fall back
-like the web (`state.view` is the resolved view). Opening a revealed section with `s=`
-clears its shine.
-`catalog`: `0` leaves `state.catalog` out; the `catalogVersion` of the catalog the client
-has leaves it out while it's unchanged (it changes when admins change the config). Without
-it the catalog comes as before. `state.catalogVersion` is always there.
-
-Response `200`: `{ok: true, userId, newPlayer?, state}`.
-
-## POST /api/act/&lt;action&gt;
-
-Body: form (`application/x-www-form-urlencoded`) or a JSON object (strings, numbers,
-booleans; `true` is sent as `"1"`, `false` as unset). Query params work too. Include the
-current view (`s`, `moon`, `well`, …, `include` and `catalog`) to get the state for it back.
-`clientSeq` (optional, any string or integer) comes back as `clientSeq` in the response
-(an integer comes back as a number, so `"007"` becomes `7`), on 200 and 422, so a client can match responses to the
-predictions it queued.
-
-Core-loop actions and their params:
-
-| action | params | notes |
-|---|---|---|
-| `buy-moon` | – | view moves to the new moon |
-| `stake` | `tool` (tool id), `target` (well id) | deploy; any idle copy of the tool may be used |
-| `claim` | `claim-well` or `claim-moon` or `claim-wide` (moon id), `redeploy=1` | no scope: claim all (needs `unlocked["claim-all"]`); `redeploy` needs `unlocked.redeploy` |
-| `redrill` | `redrill-well` (well id) | redeploy idle tools that last mined the well |
-| `sell` | `resource`, `amount` or `all=1` | resources and refined items |
-
-The other sections' actions:
-
-| action | params | notes |
-|---|---|---|
-| `buy-tool` | `id` (store item id) | response has `buyModal` |
-| `upgrade` | `tool` (tool id) | `drill=` follows the copy upgraded |
-| `sell-tool` | `tool` | idle, nothing to claim, not the last tool (`noSale`) |
-| `buy-attachment` | `item` (attachment name) | |
-| `equip`, `unequip` | `item` (attachment name), `to` (tool id) | `drill=` follows the copy used |
-| `sell-attachment` | `item` | a spare one |
-| `refine` | `recipe` (refined item name), `qty` or `all=1` | `all` makes as many as possible (`maxQty`) |
-| `collect` | `job` (job id), or none for every finished batch | |
-| `buy-slot` | – | refinery slot |
-| `hire` | `advisor` (name) | needs a free seat |
-| `buy-seat` | – | advisor seat |
-| `sell-moon` | `sell-moon` (moon id) | `moon.sale.canSell`; view moves to another moon |
-| `new-game` | – | creates a new player and returns its id and state |
-
-Responses:
-- `200` `{ok: true, userId, clientSeq?, toast: {message, error: false, kind}, fx: {kind, finished, credits}, reveal?, buyModal?, state}`.
-  `kind` is the action (for sounds and effects); `finished` lists moons the action mined
-  out; `credits` is what a market sale earned. `reveal` (after `buy-moon`) and `buyModal`
-  (after `buy-tool`) are one-shot results, see below.
-- `422` rule violation or locked action: `{ok: false, error, toast: {message, error: true, kind: "error"}, state}`.
-  A locked action (its part of the game not revealed yet) says "Not available yet".
-- `400` bad body, `404` unknown action, `429` too many new players, `403` banned,
-  `500` `{ok: false, error: "Something went wrong"}`.
-
-## GET /api/moon-settings
-
-The procedural-moon look tuned by admins on `/utils/moons` (no player needed): the saved
-JSON object, or `null` when none is saved. Merge it over the defaults (`DEFAULTS` in
-`web/static/js/terrain.js`; unknown keys and wrong types are ignored, see
-`mergeSettings`), then build each moon from its id like `terrain.js` does. Cache it for the
-session; the web page also reads it once per page load.

-| `unlocked` | `{moons, equipment, market, store, refinery, advisors, leaderboard, help, new-moon, claim-all, redrill, redeploy}`: booleans; hide what is false |

-          attachments, slots, freeSlots, selected, stake, next, preview, ladder, resale, noSale, bonus, gear}],
- drill}
-```
-
-- Copies of a tool (same type, tier and attachments) are one row: `count` copies, `idle`
-  of them idle; `id` is the copy shown (the selected one, else an idle one), `stake` its drill.
-- `image`: the tool's art at its tier, like `state.tools`.
-- `next`: the next tier, `null` at the max: `{tier, price, parts: [{name, need, have}],
-  canAfford, blocked, short, blockedText, shortText}`; `blocked` is `credits` or `parts`
-  (`""` when it can be bought), `short` the credits missing; `blockedText` the button's
-  tooltip ("Need ₥750 more", "Need 2 Dusk Alloy (you have 0). Make it in the Refinery"),
-  `shortText` the line under it when credits are short.
-- `preview`: what the next tier changes, with the player's bonuses now: `{tier, yieldFrom,
-  yieldTo, secsFrom, secsTo, reachFrom, reachTo, rateFrom, rateTo, cost, paybackSecs}`
-  (`rate` is credits per hour; `paybackSecs` null if it never pays back).
-- `ladder`: every tier `[{tier, cycleSecs, yield, reach, rate, current, next}]`.
-- `resale`: what it sells for; `noSale`: `only-tool`, `claim-first`, `mining` or `""`,
-  `noSaleText` its text ("Claim its haul first").
-- `bonus`: `{speed, yield}` from advisors and its attachments (capped); `gear` the
-  attachments `[{name, image, effect}]`.
-- `drill` (with `drill=<tool id>`, else `null`): the drill panel `{toolId, slots: [{n,
-  attachment}], spares: [{name, count, cycleSecs, yield, canEquip, why, whyText, price, resale,
-  confirm}], mining, resale, noSale, noSaleText, confirm, idleSame, idleBest, deployTo, ladder,
-  gear}`. `attachment` is `""` for an empty slot (unequip with `item=<name>&to=<toolId>`); a
-  spare's `cycleSecs`/`yield` are the drill's with it equipped, `why` is `fitted` (one is on
-  already) or `full`; `confirm` (panel) is the sell-tool dialog, a spare's the
-  sell-attachment one. `gear[].effectText` e.g. "+20% speed". While it mines, `idleSame` idle tools of its type, `idleBest` the one to deploy
-  and `deployTo` its best well (a suggestion, as in `buyModal`).
-
-### store (`s=store`)
-
-```
-{tools: [{storeItemId, name, code, image, description, price, canAfford, owned, yield, cycleSecs, reach, rate, bestRate, whyText}],
- attachments: [{name, image, description, effect: {speed, yield}, effectText, price, canAfford, spare, equipped, resale, whyText}]}
-```
-
-`whyText`: the disabled Buy button's tooltip ("Need ₥1,400 more"), `""` when affordable.
-
-`yield` and `cycleSecs` are the base stats the card shows; `rate` is credits per hour it
-would earn with the player's advisors, `bestRate` the same for their best tool (0: none).
-
-### refinery (`s=refinery`)
-
-```
-{slots: [{n, job: {id, slot, item, qty, start, end, ready, progress} | null}], slotCount, maxSlots,
- nextSlot, nextSlotPrice, canBuySlot, free, ready, maxBatch,
- recipes: [{item, tier, seconds, price, sellPrice, inputs: [{name, need, have}], inputValue, gain,
-            maxQty, bulkQty, bulkSecs, bulkBonus, owned, why, whyText}],
- stock: [{name, amount}], buySlot, buySlotWhyText}
-```
-
-`nextSlotPrice` is 0 at the cap. Per recipe: `inputs` per unit, `maxQty` what one batch
-can make now, `bulkSecs` how long a batch of `bulkQty` takes, `bulkBonus` the percent
-saved per unit, `sellPrice` one unit's price now (as the market quote), `why` `busy` (no
-free slot), `inputs` or `""`, `whyText` its text ("All slots are busy", "Not enough
-inputs"). `buySlot` is the buy-slot dialog (`null` at the cap), `buySlotWhyText` why
-"+ Slot" is disabled. Refined items sell through `sell` like resources.
-
-### advisors (`s=advisors`)
-
-```
-{seats, hired, maxSeats, nextSeat, nextSeatPrice, canBuySeat, seatFree, bonuses, buySeat, buySeatWhyText,
- advisors: [{name, title, image, description, price, effect: {speed, yield, sell, refine}, effectText, hired, canAfford,
-             canHire, why, whyText}]}
-```
-
-`buySeat` is the buy-seat dialog (`null` at the cap), `buySeatWhyText` why "+ Seat" is
-disabled. An advisor's `why`: `hired` ("On your board"), `seats` ("All seats taken. Buy
-another seat first"), `credits` ("Need ₥X more") or `""`.
-
-### leaderboard (`s=leaderboard`)
-
-`{players, top: [{rank, name, credits, me}], you, me: {rank, credits}}`: `you` is the
-player's row when they're not in `top` (else `null`); `me` their place either way.
-
-### help (`s=help`)
-
-`{steps: [string], note, newGame}`: the "How to play" steps (the web's text; `note` says
-progress is saved on this device). Its button is `new-game`, `newGame` its dialog.
-
-### newMoon (`s=new-moon`)
-
-`{price, canAfford, after, need, types, resources, wellsMin, wellsMax, whyText}`: `after` the
-balance after buying, `need` the credits missing, `whyText` why the button is disabled, `types` the moon types it can roll,
-`resources` what its wells can hold. Buy with `buy-moon`.
-
-### reveal (in the `buy-moon` response)
-
-```
-{moonId, name, kind, description, rating, headline, sub,
- worth, multiple, traits: [string], maxSupply, fullAt, wells: [{id, resource, supply, full}]}
-```
-
-`headline`, `sub` and `traits` are the card's verdict text; `worth` its wells at market
-prices, `multiple` worth / its price; a well bar is `supply / maxSupply`, `full` from
-`fullAt`.
-
-### buyModal (in the `buy-tool` response)
-
-`{toolId, storeItemId, cycleSecs, yield, reach, noMoons, allEmpty, suggestions: [{moonId,
-moonName, wellId, resource, supply, credits, perMin, idle, reason}]}`: up to 3 wells to
-deploy the new tool on (`stake` with `tool=<toolId>&target=<wellId>`), best first;
-`reason` `best-value`, `most-supply`, `no-drill` or `shared`, `reasonText` its text
-("Highest value").
-
-### moon.sale (with `s=moons`, once `unlocked.store`)
-
-```
-{total, market, replace, delta, capped, factor, lines: [{resource, supply, rate, value}],
- last, running, ready, holdEnd, canSell, why, whyText, confirm}
-```
-
-`total` is the offer (`market` × `factor`, capped), `replace` a new moon's price after the
-sale, `delta` = total − replace; `ready` finished drills are claimed in the sale.
-`why`: `last` (only moon), `running` (drills on it), `hold` (sellable at `holdEnd`) or `""`;
-`whyText` the web's text ("Wait for 2 drills to finish", "Just bought: you can sell it in
-4:27", at `now`); `confirm` the sell-moon dialog.
-
-### market chart (`s=market`)
-
-`market.chart`: `{item, start, step, prices}`, the selected quote's 24h market rate (before
-events, advisors and pressure), one point every `step` ms from `start` (289 points, the last
-is now). Each quote's `spark` is every 3rd point plus the last (the web's sparkline).
-
-## Texts
-
-Confirm dialogs (`confirm`, `buySlot`, `buySeat`, `newGame`): `{title, text, ok, danger}`,
-the web's title, question, OK button and whether it's destructive, e.g.
-`{"title": "Sell drill", "text": "Sell this Prospector Drone PD-1 (T0) for ₥750? Its
-attachments go back to your inventory.", "ok": "Sell for ₥750", "danger": true}`. Texts with
-a time in them (`whyText` of a held moon, a banner's `left`) are as of `state.now`.
-
-Not sent (the client words them from the numbers, like the web's templates):
-- moon list status: "N drills", "Idle", "Tapped out"; "A well here has more drills than
-  supply" (`over`).
-- well note: "Over-drilled — next claims will come up short", "Fully committed", "X left · Y
-  committed · runs dry after N claims" / "Z free after" (`demand`, `remain`, `dryAfter`).
-- deploy card: "Only X left after current drills", "Well spoken for: nothing left after
-  current drills" (`well.idle[].short`, `here`, `free`).
-- market: change ("+1.25%"), pressure ("−12%"), boost ("×2"), advisor ("+10%").
-- upgrade payback ("pays back in 2h 5m"), "Max tier", empty states ("No idle tools.").
-
-The web's formats:
-- credits: `₥` + the amount with thousands commas and up to 2 decimals (`₥1,234.5`);
-  amounts the same without `₥`. Compact (per hour): `₥1.2M`, `₥45k`, `₥1.5k`, else whole.
-- cycles: `3s`, `2m`, `2m 30s`; longer spans `2h 5m`. Countdowns `m:ss`, `h:mm:ss`.
-- banner time left: `2d 4h left`, `3h 20m left`, `45m left`.
-- bonuses: `+` and the percent with one decimal at most (`+10%`, `+12.5%`).
-
-## Prediction
-
-The client may show results before the server answers; the next state replaces them.
-- Stake: a drill takes `tool.cycleSecs` and gets `tool.yield` (× `rules.boosts.yield` of
-  the well's resource, if any). Each stake carries `start`, `end` and `take` (what claiming
-  it would get now).
-- Sell: `amount` units pay `amount × unpressed × avg`, with
-  `avg = floor + (1 − floor) × scale × (e^(−p/scale) − e^(−(p+d)/scale)) / d`,
-  `p` the quote's `pressure`, `d = amount × base` and `floor`, `scale` from
-  `rules.pressure` (`avg` is `factor` when `d` is 0). `sellAll` is that for the whole
-  balance. Pressure then becomes `min(p + d, rules.pressure.cap)` and halves every
-  `halfLifeSecs`.
-- Refine: a batch of `qty` takes `round(seconds × qty^bulkExponent / speed)` seconds
-  (`seconds` per recipe, the rest in `rules.refinery`).
-- Every response's `state.now` is the server clock; `clientSeq` matches a response to its
-  request.

-# Drill attachment art
-
-The attachment images (`web/static/assets/attachments/<image>`, `image` in
-`config/game.json` `attachments.items`) are rendered in Blender (4.5 LTS, Cycles on
-CPU) with the equipment pipeline: `art/equipment/lib.py` for materials, the regolith
-ground, world, lights, camera and render settings.
-
-```sh
-art/attachments/render_all.sh                # all four
-art/attachments/render_all.sh diamond-bit    # just one
-```
-
-`render.py` builds and renders at 1024px, `finish.py` (system `python3` with Pillow)
-writes the 512px PNGs and contact sheets in `build/`. `--res N` and `--samples N`
-give quick previews.
-
-`parts.py`: one build function per attachment and `PARTS` (key = image name, detail
-scale `S`, ground seed).

+# AGENTS.md — Moon Miners client (Defold)
+
+A native client for Moon Miners (rules and state live in the Go server: `../server`,
+`../server/AGENTS.md`; the repo: `../AGENTS.md`), and the only game client. Layout and HUD
+look come from the old web client (header, moon list left, the section in the middle, aside with the moon viewport and the
+selected well; on Moons the aside only shows, every action is on the well cards), made game-native. Target 16:10 at 1280x800 (Steam Deck); bigger windows
+show the UI at native pixel size with more room, smaller ones rearrange. Mouse now,
+gamepad later. Details live in each file's header comment; this file has the rules and a
+map.
+
+## Rules
+- The server is the authority. Show the state it sends, send actions. Prediction may show
+  an action's result early, computed only from numbers the server sent (`take`, the tool's
+  `cycleSecs`/`yield`, quotes, `rules`; `../server/api.md` "Prediction"); the next response
+  replaces it. No other game rules in Lua. Countdowns tick locally as display only.
+- Keep changes small; don't touch `../server` from here.
+- Flex-first: new or reworked UI is laid out with `modules/flex.lua` / `flex_gui.lua`, no
+  hand-placed coordinates (`26 + ui.text_width(name) + 7`). When you touch a hand-placed
+  part, port it. The point is fewer layout bugs and less rework, not fewer lines.
+- Slot rule: layout owns an outer slot node per box (an `anim.group`, a card's root, a
+  label); animations own what's inside (CSS layout vs transform). Never give a box a node
+  that something animates by position or size. Widgets built at a size (ui.button, bars,
+  dashed edges) are built after the solve at their box's rect; text is cut after it
+  (`ui.fit_text`). Kept blocks aren't re-laid out: solve only what you build.
+- Clicker rule: buttons never move under the pointer while the player clicks. Nothing above
+  a button changes its position (reserve room: fixed heights, placeholders), and when a
+  thing is used up the next of its kind slides into the same spot (refinery slots, deploy
+  cards), so repeated clicks at one place keep working.
+- Input focus: the game screen takes input focus once in `init`. Druid never touches it
+  (`[druid] no_auto_input = 1`: a Druid instance's `final()` would release focus for the
+  whole gui script, so closing a dialog left the game deaf). Don't post
+  acquire/release_input_focus anywhere else. The dialog's input invariant
+  (`dialog:check`) logs `ERROR:MM: input invariant broken` when repaired; check.py fails on
+  `ERROR:MM`.
+- One Monarch screen (`game`). Dialogs are `g.dialog` (components/dialog), never screens.
+  One Druid instance per gui_script (the dialog has its own). Interaction goes through
+  Druid via the components; a raw `druid:new_button` is mouse-only and has no test id.
+- Every interactive element registers a stable test id (button.bind, tabs.tab, row, field
+  do; ids in `modules/test.lua`'s header). Give new interactive things an id: focus,
+  keys, fx and the test driver depend on it.
+- Build from templates cloned at runtime (`ui.clone`; new kinds: a template in
+  `gui/templates/`, instanced under `protos` in `game.gui`). Template roots are pivot NW;
+  layout is top-left based (x right, y down).
+- Rebuilds: a section that reads a new state key adds it to `SECTION_KEYS` (core/main.lua;
+  `ASIDE_KEYS` and the header's sig likewise; the moon list's rows: `moonlist.rows_sig`;
+  the moon's facts in the aside: `aside.facts_sig`; the Moons parts: their models in
+  moons.lua) or it won't update. The shown state is frozen (`blocks.freeze`: `blocks.sig`
+  writes each part once per state, by content): never change `g.state` in place; a
+  prediction changes its copy before it is shown. What must survive
+  a rebuild lives on `g` or on a layer outside `g.layout`; never keep a layout node across
+  builds outside its block. A new per-build registry notes its entries in the block journal
+  (`blocks.note`/`push`/`put`); code that builds outside a build runs through
+  `blocks.bound(fn)`.
+- Theme: every color is a token (`theme.color`, dark and light, from the old web client's CSS): no hex or
+  vector colors in code (templates via `theme.template`, config colors via `theme.item`,
+  glows via `theme.glow_blend()`). The moon viewport stays dark. Sizes from `theme.size`.
+- Text: styles from `theme.text`; `₥`, `★` and other symbols through the `sym` font
+  (`ui.credits`, `ui.label`). `ui.text` escapes markup unless the style has `markup = true`;
+  server text is safe to pass. Add missing characters to the `.font` (make check names them).
+- Node budget: `max_nodes: 4096` in `game.gui`; text past the font batch limit silently
+  doesn't render (make check catches the warning); stencils and images split batches.
+  Outline textures use slice9 2.
+- Motion: easing curves match the old web client (`modules/anim.lua`). GUI nodes don't pass alpha to
+  children: fade content in from under a veil, not by fading a subtree. Every new
+  animation honors reduced motion (`anim.reduced`). Effects for action results go in
+  `modules/fx.lua`; numbers that change ease (`H.tick_num`); the wallet counts through fx.
+- Scaling: layout size = window / (UI scale × display scale); below 960x600 it scales down;
+  below 1250 wide the aside gets its own row and the page scrolls. Content caps
+  (`theme.size`) are all above what fits at 1280x800; keep it that way (compare shots).
+- Web: use dt or the clock for motion (variable frame rate); after render changes check the
+  browser console (WebGL feedback loops, Firefox target resizes).
+- Native code (`mmwindow/`, `mmterrain/`): user rule, C only (`.c`, Lua C API); C++ only
+  where the dmSDK forces it, as a C-style shim (free functions and plain structs: no
+  classes, methods, templates, STL, references, own namespaces, exceptions, RTTI). The
+  extender compiles `.c` as C++, so the C must also be valid C++, with `extern "C"` across
+  files. Changing a native extension (or the dependencies) sends a remote engine build.
+- `[mm]` in `game.project` holds only the keys in `scripts/check.py` `MM_DEFAULTS` at their
+  shipped values; pass others with `--config=mm.<key>=<value>`. Don't change
+  `display.width/height`.
+- Never kill processes by name; scripts stop the game by its pid.
+
+## Testing
+- Use your own server and database: `../scripts/wt up <task>` (see `../AGENTS.md`) prints
+  the `MM_API` to use. Never test against the dev server on :3000, never touch the user's
+  running game or their settings file (`~/.local/share/moonminers/settings`): give any game
+  you start its own `XDG_DATA_HOME` (drive.py does: `<out>/data`).
+- After a visual change, look at it: `make drive SCENARIO=sections MM_API=...` (or
+  `scripts/views.sh` against a baseline) at 1280x800 and 2560x1600, and the dialog when you
+  touch it. Add a scenario per feature (`scripts/scenarios/*.py`; each file's docstring
+  says what it checks and needs). Run `make check` (with `MM_API` set to your test
+  server; it makes a fixture player there) before calling it done.
+- Drive commands (`scripts/drive.py`, through the test hook): `click(id | prefix |
+  "label=<text>")`, `hover`, `scroll_to`, `key`, `type`, `navigate`, `wait_for(lua expr)`,
+  `idle()`, `eval`, `elements()`, `state()`, `set(...)`, `shot(name)`, `log_has`,
+  `expect`, `restart()`, `cmd("frames", "reset")`; real X input: `os_click`, `os_move`,
+  `os_key`, `os_point`. `--attach $(cat dist/dev/port)` drives a `make dev`/`make run` game.
+- `scripts/fixture.py <api>` makes a player with every section filled (needs an MM_DEV=1
+  server, which `wt up` starts).
+- Layout lint instead of judging screenshots: `make lint MM_API=...` lints every section at
+  1280x800 and 1920x1080 and checks the clicker rule on a few actions (claim, collect,
+  sell, buy, upgrade); issues in `dist/drive/lint-<size>/lint-summary.json`. One screen:
+  `drive.py [--attach PORT] dump "{section='store'}"`. In a scenario: `game.lint(name)`,
+  `game.click_check(id)`, `game.dump(name)` (the test hook's `dump`: every shown node's
+  rect, kind, test id, text, clip). Rules and output: `scripts/ui_lint.py` header (overlap,
+  overflow, off_screen, small_hit, text_cut; moved, clicked_moved, clicked_gone). Add a
+  click_check to a feature's scenario when it has buttons people click repeatedly.
+
+## Commands
+- `make build`: `bob build bundle` (debug) into `dist/x86_64-linux/MoonMiners/`; `build/` is
+  bob's output, `build/x86_64-linux/dmengine` the engine with our extensions.
+- `make run ARGS="--config=mm.api_base=http://localhost:3101"`: build, then run the game
+  from `build/default` in the foreground (loose files, engine service on), so `make reload`
+  works on it.
+- `make dev` (same, in the background; `HEADLESS=1` under its own Xvfb), `make reload`,
+  `make dev-stop`: hot reload, below. State in `dist/dev/` (pid, port, display, game.log).
+- `make shot`, `make play`, `make drive`, `make check`, `make web`, `make serve-web`: see
+  the Makefile comments. Web build test: `make web WEB_VARIANT=debug`, `scripts/serve-web.py`,
+  `node scripts/web-shots.mjs` (Playwright; header of the script).
+
+## Hot reload (`make reload`, `scripts/dev.py`)
+`make reload` runs `bob build` (no bundle, a few seconds) and posts every changed file in
+`build/default` to the running debug game's resource reload (`/post/@resource/reload`, as
+the editor does); the game's gui script runs again and rebuilds, keeping its state (player,
+view, scroll offsets). It fails loudly on a compile error and keeps the old code running.
+- Reloads: our Lua modules (`modules/`, `screens/`, `widgets/`, `components/`) and the
+  game's `.gui_script` (tested). Other changed resources (`.gui`, atlases, fonts) are sent
+  too; restart if one looks wrong.
+- Needs a restart (reload says so; `make dev-stop dev`, or quit and `make run`):
+  collections, game objects, `main.script`, materials, shaders, the render script; modules
+  that hold state shared with other scripts (`modules.moon.*`, `modules.api`,
+  `modules.sfx`, `modules.images`, `modules.screen`, `modules.hot`); `game.project`;
+  native extensions and dependencies (a new engine).
+- New fields that `init` sets on `g` don't exist after a reload: make them in `ensure`
+  (core/main.lua) or lazily.
+
+## Map
+Game screen (`screens/game/`); `game.gui_script` forwards to `core/main.lua`. Module
+contract: `M.build(g, root, x, y, w, h, H)`, optional `M.aside`, `M.aside_below`,
+`M.update(g, dt)`, `M.teardown(g)` (header of core/main.lua). A new section: a module here,
+an entry in `M.SECTIONS` (core/main.lua), a tab in `header.lua` `SECTIONS`.
+- `core/main.lua`: lifecycle, rebuilds, build orchestration, entrances, `on_reload`.
+- `core/session.lua`: state, server requests (one at a time), prediction hookup, history.
+- `core/hooks.lua`: the `H` helpers (`action`, `link`, `claim_wait`, text blocks).
+- `core/keys.lua`: keyboard (focus, Enter/Space, scrolling keys, fields, F11, Ctrl +/-/0).
+- `core/ready.lua`: ready counts on our clock. `core/ticks.lua`: countdowns, bars, eased numbers.
+- Regions: `banner.lua`, `header.lua`, `moonlist.lua`, `aside.lua`, `settings.lua` (gear
+  menu), `savecode.lua`, `grant.lua` (admin grant dialog), `admin.lua` (admin area from the gear
+  menu, instead of the page; screens: `moonlab.lua`, the moon settings editor).
+- Sections: `moons.lua`, `market.lua` (+ `ticker.lua`, `chart.lua`, `sale.lua`,
+  `leaderboard.lua`), `refinery.lua`, `equipment.lua`, `store.lua`, `advisors.lua`,
+  `help.lua`, `moon_sale.lua`, `reveal.lua` (new-moon teaser and reveal window), `cards.lua`
+  (shared by card sections).
+- Scripted runs: `autoplay.lua`, `autoplay_refinery.lua`, `predict_demo.lua`.
+
+Components (`components/`, API in each header; build new UI from these): `button`,
+`dialog`, `panel`, `card` (+ `card.grid`), `tabs`, `list` (long lists, Druid Data List),
+`scroll`, `bar`, `chip`, `stat`, `row`, `slider`. `widgets/moon_row.lua`: the moon list row.
+
+Modules (`modules/`):
+- `flex.lua` (pure flexbox/grid solver, tests in `scripts/flex_test.lua`), `flex_gui.lua`
+  (applies it to nodes, tree builders), `blocks.lua` (kept blocks, journal). For text and
+  parts that come and go, use flex_gui's guards: `fg.reserve(style, kid_or_nil)` (a fixed
+  slot whether its content shows: a "Need ₥ more" line, a count, a note), `fg.label(...,
+  { fit = true, shrink_text = 0.8 })` (one line: shrink, then cut with …), `fg.para(...,
+  { lines = 2 })` (at most n lines, cut with …).
+- `ui.lua` (clone, text, rects, markup), `theme.lua`, `anim.lua`, `fx.lua`, `sfx.lua`,
+  `toasts.lua`, `tooltip.lua`, `focus.lua`, `field.lua`, `screen.lua` (scaling, fullscreen),
+  `settings.lua` (the settings file), `images.lua`, `tween_numbers.lua`.
+- `api.lua` (server API, `X-MM-User`), `predict.lua` (predictors), `test.lua` (test hook),
+  `hot.lua` (hot reload).
+- `moon/moon.lua` + `moon/terrain.lua`: the viewport's moon (API, the moon settings and
+  their `DEFAULTS`, the look the server's `moondesc.go` mirrors).
+
+Elsewhere:
+- `main/`: bootstrap (`main.script`, Monarch proxy, window focus, sfx object).
+- `moon/`: moon collection, `moon.script`, materials (port of scene.js).
+  `render/mm.render_script`: HDR moon pass with bloom.
+- `mmwindow/`: native fullscreen and sticky input. `mmterrain/`: native moon generator, the
+  game's only one (it began as a C port of the web client's terrain.js, now deleted).
+- `gui/templates/`: node templates. `assets/`: fonts (Rajdhani, Oxanium, Inter `sym`),
+  `ui.atlas`, `sfx/` (CREDITS.txt; `scripts/zzfx-render.mjs`).
+- `web/index.html`: the web build's page.
+- `scripts/`: `dev.py` (run/hot reload), `drive.py` + `scenarios/`, `check.py`,
+  `fixture.py`, `shot.sh`, `views.sh`, `serve-web.py`, `web-shots.mjs`, `errproxy.py`.

+# Flex layout: notes from the first port
+
+Solver `modules/flex.lua` (430 lines incl. docs), apply helper `modules/flex_gui.lua` (96),
+tests `scripts/flex_test.lua` (53 checks, in `make check`).
+
+## Lines, before -> after
+
+| File | Lines | Hand-placed offsets (`x + `, `y + `, `+ 8`, `set_position`) |
+|---|---|---|
+| `screens/game/refinery.lua` | 524 -> 595 | 35 -> 10 |
+| `components/card.lua` | 298 -> 325 | Druid Layout gone; one tree replaces three branches of padding math |
+| `screens/game/header.lua` (wallet only) | 243 -> 256 | running `cx` cursor gone |
+
+The code is longer, not shorter: every text is now a box with its line-box height, and
+the tree literals add structure lines. What it gains: no running cursors, no "measure, then
+come back and move it" (`gui.set_position(mx, vec(w - mw, -fy))`, the slot label's probe
+node, the Collect all offset `67.9 - 44`). Spacing is in one place per container, and the
+heading and stock now grow with their content (before: fixed 67.9 px, chips wrapped by
+hand).
+
+Screenshots (`shots/c-flex/before|after`, 1280x800 dark and light, 1024x640): Refinery
+(ready, idle, running slots, buy slot, recipe footers), Store, Equipment, Advisors and the
+header match pixel for pixel. The only differences are animations caught at another
+moment (Claim all, Ready glow, pulsing buttons) and fixture data. Scenarios smoke, cards,
+keys and finalcheck pass (keys timed out once on the Market tab, then passed; the baseline
+passes too).
+
+## Easier
+
+- Rows with something pinned right (time left, "have" counts, Max button), centered
+  labels, and footers pinned to the bottom: `justify`, a `grow = 1` spacer.
+- Wrapping chips and equal-height slot rows: `wrap = true` plus the default stretch.
+- Text cut to the space left: a shrinking leaf, then `ui.fit_text(node, box.w)`.
+
+## Harder
+
+- Matching the old pixel offsets exactly. The old code centers text at hand-picked middles
+  (12 for one label, 11 for the one beside it), so some rows need leaves of different
+  heights inside a fixed-height row. A new screen built with flex from the start won't
+  have this.
+- Widgets built at a size (ui.button, the cell bar, dashed edges, the quantity field):
+  solve with an empty box, then build at its rect. Fine, but it splits a component in two.
+- Creation order is focus and Druid input order, so nodes must still be built in the old
+  order; only their placement moves to the end.
+- bob follows `require` strings, and flex.apply -> flex_gui -> flex is a cycle; it uses a
+  non-literal name.
+
+## What the solver does that CSS doesn't (or does differently)
+
+- border-box sizes, `min-width: 0` by default (CSS's auto min size would stop labels from
+  being cut), auto size = fit-content even at the root, align-content always start, no
+  margins (spacer boxes), no baseline alignment.
+- No pixel snapping. One label (buy slot) is solved, then placed on a whole pixel by hand,
+  as the old code did; a `round` option could do it.
+- CSS grid's `minmax(200px, 1fr)` isn't flex: the columns are computed (as before) and
+  given to wrapped items as widths. A small `grid` helper would cover card.grid and the
+  slots.
+
+## Also fixed
+
+- `card.grid` rebuilt a kept card whose row height changed without the card options
+  (a recipe card would have gotten an image column).
+
+## Recommendation for the rest
+
+Port section by section when a section is touched anyway, not as one sweep: equipment's
+tool cards and the drill panel, store and advisors (already on Card), market's ticket and
+stats, the header's tab row (it has a "second row when it doesn't fit" rule, which is a
+wrap). Keep kept blocks as they are: solve what a build makes. Leave lists (Data List)
+and the scroll areas alone. Add a `grid` helper and rounding before the next big port.
