spike(modules): carry /public/atlas/* behind the proposed module surface

THROWAWAY BRANCH — evidence for the Phase 1 contract, never merged. See
modules/uo/SPIKE.md and docs/website/MODULE_API.md Part 7.

The six public spawn-atlas routes now live in modules/uo/, reached only through
the ctx/register surface, with the client half loading as a prebuilt ESM chunk.
All three exit criteria met:

  • zero internal-file imports from the module into core; the built chunk has
    zero bare import specifiers and bundles no React
  • routes.manifest.json AND routes.guards.json are byte-identical
  • /uo/atlas renders from /modules/uo/entry.js under script-src 'self' with
    zero CSP violation reports

729 core tests and 81 module tests pass. Verified end to end against the real
database: the schema fragment replays after core's, onBoot runs the atlas
refresh, and the six API URLs answer unchanged.

Two things the spike changed in the contract:

  • ctx.express / ctx.validator. A module lives outside server/, so Node never
    reaches server/node_modules and require('express') fails outright — the
    server-side twin of the one-React rule, which §2.6 had only for the client.
  • window.__rg.jsxRuntime, so a module can build with the automatic JSX
    runtime its tooling already assumes rather than being forced to classic.

And it confirmed §6.1 empirically: regenerating the OpenAPI spec silently
deleted all 361 lines of the atlas paths with "Swagger-autogen: Success", while
the route manifest kept all six in the same run. That is exactly the
static-analysis-vs-runtime split the fragment merge exists to prevent.

+//
+// The three navs stay declared in code, each in the component that renders it;
+// this screen writes an override *layer* over them (§7). It can relabel,
+// reorder, hide and — on the admin sidebar — move a row into another existing
+// section, and nothing else. It cannot introduce a route and it cannot touch a
+// `roles` or `feature` gate, so the filters in the layouts still decide who sees
+// what, and they run after the merge.
+//
+// Three things shape the screen:
+//
+//   • The palette is filtered to the editing admin's OWN visible rows (§8.1) —
+//     the base array run through their role and this shard's feature gates. An
+//     admin cannot drag in, and so can never accidentally advertise, something
+//     they cannot see themselves. An override on a row they cannot see is
+//     carried through their save untouched rather than quietly reset.
+//   • The rows come from the same merge the site renders (buildNavRows), hidden
+//     ones included, so the editor cannot show an order the nav does not use.
+//   • Saving writes a settings row; "reset" DELETES it. Absence of the row is
+//     what selects the coded default, so reset cannot store a copy of it — and a
+//     save whose result is empty deletes the row for the same reason (§4.1).
+
+// The nav editor's own row. Hiding it would remove the only screen that can
+// un-hide it, so its eye toggle is disabled here and the server drops `hidden`
+// on it as well (server/src/utils/navOverrides.js) — a hand-written row cannot

+// the data is gathered (docs/link/v3.md §8):
+//
+//   • **The prices are not live.** The shard sweeps vendors round-robin, so a
+//     shop can be a full cycle behind. The banner says how far, from `staleAt`.
+//     A page that implied live prices would send people across the world to a
+//     vendor whose item sold twenty minutes ago.
+//   • **A shop can be truncated.** A commodity reseller with thousands of stacks
+//     publishes only the first N, and saying so beats presenting a partial shop
+//     as complete.
+//   • **An item may have no name.** On a shard whose operator has not converted
+//     a cliloc table, `displayName` is null and the honest render is the item id
+//     — not an invented name.
+//
+// There is deliberately no live feed here. The market feature's SSE stream ships
+// disabled: a firehose of whole vendor inventories would be the site's single
+// biggest bandwidth consumer, and nothing on this page needs it.

+# module-uo — the Phase 1 spike
+
+**This branch is evidence, not implementation.** `spike/module-atlas` is cut from `edge` and is
+never merged. Phase 2 rebuilds the loader properly, with the `installed_modules` table, the full
+state machine and the admin panel behind it; Phase 3 does the real extraction.
+
+What it demonstrates, and the results, are written up in
+[`docs/website/MODULE_API.md`](../../../docs/website/MODULE_API.md) Part 7. In one line: the six
+public spawn-atlas routes now live in a module, at byte-identical URLs, with the client half loading
+as a prebuilt ESM chunk under `script-src 'self'`.
+
+## Reproducing it
+
+```bash
+# 1. build the module's client chunk (its CI would do this and ship the result)
+cd modules/uo/client && npm install && npm run build     # → dist/entry.js
+
+# 2. build core's client
+cd ../../../client && npm install && npm run build
+
+# 3. run the server against the local MariaDB
+cd ../server && npm start
+```
+
+Then:
+
+- `/uo/atlas` and `/uo/atlas/lizardman` render from the module's chunk.
+- `GET /api/v1/public/atlas/*` answers exactly as before — `npm run routes:manifest -- --check`
+  reports the surface unchanged.
+- `npm test` in `server/` (core, 729) and `node --test` in `modules/uo/server/` (module, 81).
+
+`dist/entry.js` is committed here **only** because this branch is the evidence for a design
+decision and a reviewer should be able to inspect the built artifact without a toolchain. A real
+module publishes it from CI into its release bundle and never commits it.
+
+## What in here is not design
+
+Three things are consequences of stopping at six routes, spelled out in MODULE_API.md §7.5:
+
+1. **Core reaches into this module twice** — `server/src/router/v1/admin/shardAtlas.controller.js`
+   and `server/test/atlasController.test.js`. The five admin atlas routes sit inside the `/shard`
+   admin prefix core still owns, so they cannot move until the whole prefix does.
+2. **`server/utils/visibility.js` is a copy** of core's `utils/shardVisibility.js`, which core still
+   needs for the shard routes not yet extracted. Two caches over one table, briefly.
+3. **There is no `swagger-fragment.json`** — it needs core's merge helper on the other side, which
+   is Phase 2.
+
+Also note the table names here are `shard_*`, not `uo_*`. That is deliberate and grandfathered by an
+allowlist in the loader: renaming twenty-seven live tables is a data migration this workstream does
+not do. Every module written after this one carries its id as a table prefix.

+//   theme.css's `:root` remains the default and is NOT duplicated here beyond

+//   `theme` block at all and renders from :root exactly as it does today.

+//      comes up either way, serving whatever table it already had (or none, in
+//      which case the UI falls back to item ids exactly as it did before).
+//   2. **Nothing client-derived is committed.** The table is built from the
+//      operator's own file at a configured path. The repo ships no strings.

+// The table is built from a SET of sources — the converted client table plus

+// them are re-read on every boot and hash-gated together, so adding one custom
+// item never means re-exporting a 5 MB client file. Later sources win.
+//
+// That set is also why this has the atlas's escalation, in a lighter form. A
+// single corrupt file fails the parse loudly, but a source that has simply
+// VANISHED parses perfectly and imports a table quietly missing everything it
+// contributed — the same ambiguity (real change vs half-copied mount) the atlas
+// stages a facet removal for. So a disappearing source is refused and reported
+// rather than applied.
+//
+// It is lighter than the atlas's because it needs to be: the atlas stores a
+// pending decision in its own table and adds approve/reject endpoints, whereas
