Capture a Linux-container ScriptC spike next to the Hub backend so we can compare Node vs native deploy size/RSS and record coverage limits for a full backend with dynamic plugins. Co-authored-by: Cursor <cursoragent@cursor.com>

Adds a throwaway
packages/backend-scriptcspike that builds Linux ScriptC and Node twin images, benches size/startup/RSS, and runsscriptc coverage --dynamicup a ladder toward the real Hub backend. The package is excluded from Yarn workspaces so Konflux/hermeto never seescriptc.Findings (high level): A trimmed HTTP + zod PoC works on Windows via Podman (no Mac required). ScriptC image ~86 MB vs Node twin ~228 MB (~2.7×); process RSS ~6 MB vs ~62 MB (~10×).
createBackend()and a core static plugin set are coverage-green with--dynamic, but addingdynamicPluginsFeatureLoaderhits SC1090 and fullpackages/backend/src/index.tshas more SC blockers. True dynamic plugins also conflict with scriptc’s build-time embed model (no runtimenode_modulesload). Full Hub + dynamic plugins is not ready; the next backend-like compile target is the static-plugin rung. Details are inpackages/backend-scriptc/REPORT.md.Review starting points: root script wiring + workspace exclusion in
package.json, thenREPORT.md, then the Containerfiles /src/main.ts/ coverage ladder undersrc/entries/.
