+# Plan: Drop node18 target, add node22 target
+
+## Context
+
+The project currently supports `node18` and `node20` as compilation targets (plus `host`). The user wants to drop `node18` and add `node22` instead, updating CI, source code, tests, and documentation accordingly.
+
+## Changes
+
+### 1. CI Workflows
+
+**`.github/workflows/ci.yml`**
+
+- Change build matrix from `[18.x, 20.x]` to `[20.x, 22.x]`
+- Change lint condition from `node-version == '18.x'` to `node-version == '20.x'`
+- Replace `test_18` job with `test_22` (calling `test:22`)
+- Keep `test_20` and `test_host`
+
+**`.github/workflows/test.yml`**
+
+- Change test matrix from `[18.x, 20.x]` to `[20.x, 22.x]`
+
+### 2. Package configuration
+
+**`package.json`**
+
+- Update `engines.node` from `>=18.0.0` to `>=20.0.0`
+- Replace `test:18` script with `test:22`: `"node test/test.js node22 no-npm"`
+- Update `test` script to call `test:22` instead of `test:18`
+
+### 3. ESM Transformer
+
+**`lib/esm-transformer.ts`** (line 379)
+
+- Change esbuild target from `'node18'` to `'node20'` (new minimum supported version)
+
+### 4. Tests
+
+**`test/test-42-fetch-all/main.js`** (line 18)
+
+- Change `nodeRanges` from `['node18', 'node20', 'node22']` to `['node20', 'node22']`
+
+**`test/test-50-fs-runtime-layer-3/main.js`** (lines 29-32)
+
+- The `node18`-specific branch is no longer needed. Since we only target node20+, the error message is always the ENOENT variant. Remove the `node18` conditional and use the `node20+` behavior unconditionally.
+
+### 5. Documentation & templates
+
+**`lib/help.ts`** (line 35)
+
+- Update example from `node16-linux,node18-linux,node18-win` to `node20-linux,node22-linux,node22-win`
+
+**`README.md`** (lines 56, 85)
+
+- Update example from `node16-linux,node18-linux,node18-win` to `node20-linux,node22-linux,node22-win`
+- Update target example from `node18-macos-x64` to `node20-macos-x64`
+
+**`.github/copilot-instructions.md`**
+
+- Update node version references (node18 -> node20, matrix mention, lint reference, engines note)
+
+**`.github/ISSUE_TEMPLATE/01_bug_report.yml`** and **`02_regression.yml`**
+
+- Update example targets from `node18` to `node20`
+
+## Verification
+
+1. `yarn build` — ensure TypeScript compiles cleanly
+2. `yarn lint` — ensure no lint errors
+3. `yarn test:host` — run host-target tests
+4. `yarn test:20` — run node20 target tests
+5. `yarn test:22` — run new node22 target tests
