Superseded by # which includes the required tsconfig.json changes (types: ["node"], rootDir) that Renovate's bare version bump doesn't handle. |

## What Three coupled changes to keep the toolchain current and type-safe: 1. **TypeScript 5.9.3 → 6.0.3** — latest major. TS 7 (native Go port) is next; this is the transition release. 2. **@typescript-eslint 8.56 → 8.58** — required for TS 6 support (peer dep widened from `<6.0.0` to `<6.1.0`). 3. **@types/node ^25 → ^24** — fix type-safety mismatch with the `node24` runtime. ## Why each change ### TypeScript 6.0 TS 6.0 changes two tsconfig defaults that would break the build without config updates: - `types` now defaults to `[]` (was: auto-discover all `@types/*`) → added `"types": ["node"]` - `rootDir` now defaults to `.` (was: inferred from `include`) → added `"rootDir": "./src"` Also fixed stale exclude pattern: `"__tests__"` → `"src/__tests__"` (old pattern never matched the actual path; worked by accident under TS 5.9 because all `@types/*` were auto-loaded). **No source code changes needed** — the project's TS feature surface is minimal (just `enum` + standard ESM imports). No namespaces, decorators, import assertions, or deprecated tsconfig options. ### @types/node ^24 (not ^26) | Version | Node.js line | Status (June 2026) | Safe for `node24` runtime? | |---|---|---|---| | `@types/node@^24` | Node 24 | **Active LTS** | ✅ Exact match | | `@types/node@^25` | Node 25 | **EOL** (June 1, 2026) | ❌ Tracks a dead runtime | | `@types/node@^26` | Node 26 | **Current** (not LTS until Oct 28, 2026) | ❌ Exposes Node 26-only APIs that don't exist at runtime | `@types/node@^26` would let TypeScript compile calls to APIs that don't exist in Node 24 — exactly the class of bug TypeScript is supposed to prevent. The types version must match the runtime version. Bump to `^26` only when `action.yml` bumps to `node26` (after Oct 2026 LTS). ### @typescript-eslint ^8.58 v8.58.0 (2026-03-30) added TS 6 support. The old `^8.56.0` floor has peerDep `typescript: <6.0.0` which would emit `warnOnUnsupportedTypeScriptVersion` warnings. ## Verification | Check | Result | |---|---| | `npm run build` (`tsc --noEmit` TS 6.0.3) | ✅ clean | | `npm run lint` | ✅ clean | | `npm test` (28 tests) | ✅ all pass in 0.25s | | `npm run package` | ✅ 411 KB (unchanged — no source changes) | ## Supersedes Closes Renovate PR #117 (bare version bump without the required tsconfig changes).
