(b) does not work. The probe copies `packages/spec/src` into the scratch dir and loads it with `tsx` (cwd `packages/spec`). The copied sources import `zod` at 391 sites, plus `typescript` and `@objectstack/spec/*` self-references, and Node resolves those bare specifiers by walking up from the importing file to `packages/spec/node_modules`. Under `os.tmpdir()` that walk finds nothing. So the scratch dir has to stay inside `packages/spec/`, and (a) is the smaller sufficient fix. The codemod already removes the dir in a `finally`; the rule covers a leftover from a killed run. The gate (`exposedScratchDirs` in `scripts/pm/dispatch-gates.mjs`), its self-test and its case list are untouched. ## Readings | Reading | `origin/main` `d79eecfe` | this branch | | :--- | :--- | :--- | | `exposedScratchDirs({}).exposed` | `packages/spec/.codemod-arrays-0osprobe (scripts/codemod-split-conversions-registry.mjs:843)`, `packages/spec/.codemod-arrays-0osprobe/unpack (…:858)` | `[]`; both now `covered` by `.gitignore:74` | | `node scripts/pm/dispatch-gates.mjs --self-test` (both tiers, as the push run) | exit 1, `✗ dispatch-gates self-test: 1 of 2234 case(s) failed.`, the one ✗ being the EXPOSED line above (33 min) | exit 0, `✓ dispatch-gates self-test: 2234 cases pass.` (fast 1945 in 509 s, slow 289 in 1465 s), the case reads ✓ | ## Gates `node scripts/pm/dispatch-gates.mjs --commands` derives 8 commands for this change set; each ran on the branch: ``` node scripts/check-closing-keyword-parity.mjs :: exit 0 node scripts/check-closing-keyword-parity.mjs --self-test :: exit 0 node scripts/check-comment-mask-corpus.mjs :: exit 0 pnpm check:driver-memory-census :: exit 0 pnpm check:gitlink-declared :: exit 0 pnpm check:nul-bytes :: exit 0 pnpm check:refd-timer-probe :: exit 0 pnpm check:watch-hint-literal :: exit 0 ``` `dispatch-gates --ran`: 8 derived, 8 run, 0 NOT-MEASURED, 0 UNRUN. ## Changeset Root config only, no published package moves: `skip-changeset`. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01WGufziUhP2qtBGrqtbPFTj Co-authored-by: Claude <noreply@anthropic.com>
