// Dead-code configuration. JSONC rather than JSON so this can say what the
// gate proves — the previous JSON file could not, and the difference matters
// more here than anywhere else in the repo.
//
// ## What `pnpm knip` (the CI gate in .github/workflows/knip.yml) proves
//
// A module, export or dependency that nothing in the repository reaches is a
// build failure. That is a real property and it catches the ordinary case: a
// helper left behind after its last caller was rewritten.
//
// ## What it does NOT prove, demonstrated
//
// It does not prove a module is still reachable from production. Vitest is a
// knip plugin here, so `src/**/__tests__/**` are entry files, and a module
// whose ONLY importer is its own test counts as used — forever. Planting
// `src/lib/dead-probe.ts` with a single test importing it left `pnpm knip` at
// exit 0. Nothing in the default pass can see that class of dead code, so do
// not read a green Dead-code gate as "every module is still wired to
// something that ships".
//
// ## The pass that does see it
//
//     pnpm knip --production --include files
//
// Production mode drops the plugin-supplied test entries and keeps only the
// entry and project patterns suffixed with `!` below — the app router tree,
// the proxy, instrumentation, the pg-boss workers, and `scripts/` (maintainer
// tooling is not production, but it is a legitimate non-test consumer, so a
// module reached only from a script is not the thing we are hunting). The `!`
// suffix is inert in the default pass, so both modes read one config.
//
// This is a review tool, not a second gate, for two reasons written down so
// the next reader does not have to rediscover them:
//
//   1. It reports 29 files today. Some are test-only by construction (the
//      guard helpers under `src/__tests__/helpers/`, the settings section
//      harness) and some are deliberately unreachable from production
//      (`src/lib/ai/mock-client.ts` is excluded structurally by the
//      `PROVIDER_CHAIN_TYPES` allowlist). Baselining the rest without
//      triaging each one would encode noise as an invariant.
//   2. It has false positives. `src/lib/mood/note-backfill.ts` is imported by
//      `scripts/backfill-mood-note-column.ts` through the `@/` alias and is
//      still reported, because `scripts/` sits outside the tsconfig that
//      defines the alias. The default pass hides that resolution failure
//      behind the module's test importer.
//
// Run it in the deep-audit step, the same way
// `scripts/audit-column-readers.ts` is run: read the list, judge each entry,
// do not treat the exit code as a verdict.
