tsconfig.tier-base.json

// The base of the repo-root TIER configs (`tsconfig.node.json`,
// `tsconfig.react.json`). NOT the base of the packages — no package extends it.
//
// Renamed from `tsconfig.base.json` by objectui#9330. The old name asserted it
// was the base every package builds on; the `extends` graph below says
// otherwise, and the name had already produced two contradictory answers to
// objectui#9189's question "is there a shared base tsconfig?" — read the name
// and you set an option here, where 38 of 40 packages would never load it:
// green, inert and invisible.
//
// ⛔ The rename moved NO compiler option and added no gate. objectui#9330's
// ruling (director seat, 2026-09-13) rules a rename and a comment and nothing
// else, and objectui#7212's population question stays where it is. Anything in
// this file that changes what a project COMPILES is out of that scope.
//
// ## The measured `extends` graph
//
// Counted, not recalled: every one of the 94 tracked `tsconfig*.json` files in
// the repo, read with TypeScript's own JSONC reader (`ts.readConfigFile`), at
// cb725e78f. Re-derive it rather than trusting this block if it matters — the
// numbers below are a reading with a date on it, not a contract.
//
//   THIS FILE is extended by 3 files and by nothing else:
//     tsconfig.node.json                         editor / reference only; NO script
//                                                runs it (see its own header)
//     tsconfig.react.json                        no in-repo extender at all; named as
//                                                a template for plugin authors in
//                                                skills/objectui/guides/plugin-development.md
//     examples/byo-backend-console/tsconfig.json the one real compile that reaches
//                                                here (`tsc --noEmit`, `tsc && vite build`)
//
//   The root `tsconfig.json` is extended by 75 of the 94, every one of them
//   under `packages/`: 38 of the 40 `packages/*/tsconfig.json`, 36 of the 37
//   `packages/*/tsconfig.test.json`, and `packages/types/tsconfig.examples.json`.
//   Nothing under `apps/` or `examples/` extends it.
//
//   `packages/runner/tsconfig.json` and `packages/vscode-extension/tsconfig.json`
//   extend NOTHING — they are the two of forty that inherit from neither root
//   config. Recorded here per the ruling, ⛔ not changed by it.
//
// ⚠️ Two figures in objectui#9330's own thread disagree and neither may be
// copied forward. The card body says "all 30 `packages/*/tsconfig.json`"; the
// ruling says 38. They are the SAME population, and re-measuring at the card's
// own stated commit c64975e9f settles it: 40 such files, 38 extending the root
// config — there as well as here. 38 is right at both commits, 30 matches no
// population in this repo at either (not the published packages, not the ones
// with a build script, not the ones whose build invokes `tsc`), so it is a
// miscount rather than a narrower reading.
//
// ⚠️ The ruling names FOUR extenders of this file, including
// `tsconfig.scripts.json`. That one is wrong, and was already wrong when the
// ruling was written: `tsconfig.scripts.json` extends nothing, and its own
// header argues at length that it must not extend this file — the `exclude`
// list below drops the test globs, so inheriting it would compile none of the
// `scripts/__tests__/` pin tests that project exists for, passing vacuously.
// ⛔ Do not "complete" the ruling by adding that `extends`.
//
// Comments here are `//`, not `/* */`, for the reason `tsconfig.scripts.json`
// states: a glob containing `**` followed by `/` closes a block comment early,
// and a tsconfig that silently fails to parse falls back to including the
// entire repository.
