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

Browse Source 
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.
