Conversation
`buildBootstrapConfig` in src/server/RenderHtml.ts now returns the object the
page carries as window.BOOTSTRAP_CONFIG (environment values, plus the
per-server ones only with `perServer: true`, optional keys omitted rather than
undefined-valued). `renderHtmlContent` derives every per-field template local
from it and also passes the whole object as a `bootstrapConfig` local, unused
by today's template. Output is byte-identical to before for both modes.
The desktop release descriptor gains an optional, additive `bootstrap` field:
the environment-only object from the same builder, with the descriptor's own
assetManifest and cdnBase. Building it never reads CLUSTER_JSON. schemaVersion
stays 1 and MIN_SHELL_VERSION is untouched, so today's shells ignore the field.
New guardrails in tests/server/BootstrapConfig.test.ts: the descriptor's
`bootstrap` equals `buildBootstrapConfig({ perServer: false })` and carries no
server value; and a "Steam shell contract" test renders the real index.html
with exactly the locals the installed shell supplies, so an unguarded new
placeholder fails here rather than in the desktop repo after a release.
Step 3 (index.html collapsing to a single `bootstrapConfig` placeholder plus
the MIN_SHELL_VERSION bump) follows once the shell that reads `bootstrap` has
shipped.
Also refreshes the stale update.sh / MultiServer.md note: the site Worker is
live and serves the per-version objects from the bucket.

Make the client-field check reject extra server fields.
The contract requires every BootstrapConfig field to exist in Window["BOOTSTRAP_CONFIG"]. The current assignment uses structural typing, so extra fields on BootstrapConfig compile. Keep this as a one-way check. The client-only legacy numWorkers field means full bidirectional key equality is not required.
Proposed type-only check

- {} as BootstrapConfig;

Remove bootstrapConfig from the current-shell locals.
The current Steam shell does not supply bootstrapConfig. Including it allows an unguarded <%- bootstrapConfig %> migration to pass this compatibility test, although the installed shell would throw ReferenceError and show a blank window.
- bootstrapConfig: JSON.stringify({ gitCommit: "abc" }),Keep this local absent until the required shell version is deployed and MIN_SHELL_VERSION is increased.

Why
The Steam shell (openfront-desktop) renders this repo's
index.htmlitself, with its own EJS locals. Every unguarded placeholder added here is a ReferenceError there: #5310 blanked the desktop window, and the only protection today is a comment inindex.htmland a test in the desktop repo that runs on submodule bumps. The runtime-update template reaches players from a web deploy with no desktop change, so the break lands live.End state: the server owns the variable list in one place, the desktop release descriptor carries the rendered environment-scoped values, the shell spreads them and overrides only what it owns, and
index.htmlbecomes a single placeholder. This PR is step 2: purely additive, safe against every installed shell. The desktop side is openfrontio/openfront-desktopfeat/bootstrap-config-local(shell 0.1.3).What
buildBootstrapConfig({ perServer, assetManifest, cdnBase })insrc/server/RenderHtml.tsreturns theBootstrapConfigobject.renderHtmlContentnow derives every per-field local from it, and also passes the whole object as abootstrapConfiglocal (unused by today's template, ready for step 3). Optional keys are omitted, never undefined-valued. A compile-time check ties the type toWindow["BOOTSTRAP_CONFIG"].bootstrapinsrc/server/DesktopRelease.ts: the environment-only object (perServer: false), so no cluster, instanceLetter, instanceId, serverHost or siteHost, and no read ofCLUSTER_JSON. Both/desktop/release.jsonandRenderDesktopDescriptor.tsgo throughbuildDescriptor.schemaVersionstays 1 andMIN_SHELL_VERSIONis untouched.tests/server/BootstrapConfig.test.ts(16): builder shape in both modes, page equals builder, byte-exact environment-only block, descriptor carries env values and no server values and equals the builder, builds withCLUSTER_JSON="", and a Steam shell contract test that renders the realindex.htmlwith exactly the shell's frozen locals list. An unguarded placeholder now fails CI here rather than in the desktop repo after the fact. It already caught one: a draft of theindex.htmlcomment spelled a placeholder out inside an HTML comment, which EJS evaluates.index.htmlcomment block (placeholders unchanged),docs/MultiServer.md, and the staleupdate.shnote that said nothing serves the per-version objects yet. The site Worker is live and serves them from the bucket (x-openfront-served: bucketon openfront.io and main.openfront.dev).Byte identity
Rendered the real template with
origin/main'sRenderHtml.tsand this one across 3 env variants ×perServertrue/false × GAME_ENV dev/staging/prod plus default opts: 21 comparisons, all identical (before theindex.htmlcomment edit, which changes only the comment text).Behaviour to be aware of
buildDescriptornow callsServerEnv.turnstileSiteKey(),jwtAudience()andgitCommit(), which throw when unset. Real deploys always set them (the page render already requires them), but a container missingTURNSTILE_SITE_KEYnow fails at descriptor render time rather than at first page render.
