tsconfig.test.json

// The TEST-layer type-check program (#14062 — the `packages/plugins/**` family
// adopting the mechanism #5286 set for `packages/spec`, #5449 generalised,
// #12542 carried to `packages/rest` and #13176 to `packages/plugins/
// plugin-security`). `tsconfig.json` beside this one stays exactly as it is: it
// is the BUILD config. This sibling puts the test layer in front of tsc under
// the module semantics vitest really executes it with, and `package.json`'s
// `typecheck` script NAMES it (via `check:test-typecheck --project`), because a
// config no script invokes is exactly the phantom this whole change is about.
//
// The family was onboarded as a family by the director ruling of 2026-09-01 on
// #14062 (maintainer verbatim: 「同意」), which also carries the #5286
// maintainer authority for the starting ledgers. The reason it is a family and
// not one package: the ledger's shrink-only guarantee said NOTHING about a
// third of the repo's runtime surface, and a guarantee with a silent hole is
// worse than a narrower one honestly drawn, because readers generalise it.
//
// What differs from the build config, and what deliberately does NOT:
//   - MODULE SEMANTICS ONLY, plus `lib`. The tests are written and executed as
//     ESM by vitest (esbuild/vite). Matching that is FIDELITY, not laxity: it is the
//     same subtraction `packages/spec`, `packages/rest` and `plugin-security`
//     each made, and it removes a config-tier error pile that says nothing
//     about the tests.
//   - ⛔ STRICTNESS IS UNTOUCHED. `strict`, `noUnusedLocals`,
//     `noUnusedParameters`, `noImplicitReturns`, `noFallthroughCasesInSwitch`,
//     `rootDir`, `paths` and `types` are all INHERITED from `tsconfig.json`
//     (and through it the root config), and none of them is re-declared here.
//     ⚠️ A child that declared its own `paths` would REPLACE the parent map
//     rather than merge into it, silently sending a source-resolved specifier
//     back to `dist/` — a BUILD ARTIFACT — so this file declares none.
//     Nothing here may loosen a type rule; if a test does not compile, that is
//     the finding.
//
//   - `lib: ["ES2022"]`, for the same reason `packages/rest` states: the root
//     config's `lib` is ES2020 and vitest runs on a Node that has es2022
//     builtins, so the gap is reported as TS2550 about the CHECK. No `DOM`:
//     nothing in this layer touches a browser global.
//
// MEASURED at e80889095, workspace closure built first (`tsc --noEmit --pretty false
// --listFiles -p tsconfig.test.json`, and the same command without `--listFiles`):
//
//   files in this program        488
//   own `src/**/*.test.ts` in it 30
//   errors under BUILD semantics 3
//   errors under THIS config     3
//
// The two readings agree, so this package carried no config-tier pile at all.
//
// BEFORE THIS FILE: the build config's `exclude` NAMED `**/*.test.ts`, so
// none of the 30 test files here reached any tsc program the `typecheck`
// script runs. The two `.pin.ts` files (`exec-context-annotation.pin.ts`,
// `logger-required-warn.pin.ts`) do NOT match that pattern and were already
// in the build program — their directives were live before this file
// (#14062).
//
// The 3 residual error(s) are PRE-EXISTING — this change edits no test file, and
// every one of them would have been reported on `origin/main` had this program always
// existed. They are ledgered per file in `test-typecheck-debt.json` beside this config,
// EXACT and shrink-only: a file that gains an error is red, one that loses an error is
// red until re-recorded, one that reaches zero is red until its entry is deleted, a
// signature that ARRIVES or VANISHES is red even at an unchanged file total, and a file
// NOT listed there may have no errors at all. ⛔ The ruling is explicit that this PR
// does not REPAIR them — it makes the ratchet able to see them; paydown follows the
// ratchet's own shrink-only discipline, on its own cards.
