 - A note is a zettel when its filename starts with a **TIMEID**: a run of 12 to 18 digits

+  are ignored, so plain notes, daily notes, Excalidraw and Kanban files are never renamed.
 - The TIMEID is minted **once** and never changes. Only the slug tail is regenerated.

 - Sync is strictly one-way, H1 to filename. Renaming a file by hand is never fought.
 - Delete the H1 and the filename collapses back to the bare `TIMEID.md`.

 ## Development
 
-- `npm install` (or `pnpm install`).
-- `npm run dev` - compile in watch mode.
-- `npm run build` - typecheck and produce `main.js`.
-- `npm test` - run the slug unit tests on Node's built-in test runner.
-- `npm run lint` - eslint with the Obsidian ruleset.
+Dependencies are managed with **pnpm** (see "Why pnpm, not npm" below). Node 22+ ships
+`corepack`, so you do not need to install pnpm globally, and the `packageManager` field in
+`package.json` pins the exact version.
+
+```bash
+corepack pnpm install     # first time, or after a dependency change
+corepack pnpm run dev     # compile in watch mode
+corepack pnpm run build   # typecheck and produce main.js
+corepack pnpm test        # run the slug unit tests (Node's built-in runner)
+corepack pnpm run lint    # eslint with the Obsidian ruleset
+```

-wiring lives in `src/main.ts`.
+wiring lives in `src/main.ts`. Tests run on Node's built-in test runner (`node --test`) - there
+is no vitest or jest dependency.
+
+### Why pnpm, not npm
+
+**Do not run `npm install` or `npm ci` in this repo.** This project is developed on a **ZFS**
+filesystem, and npm's installer renames many directories in parallel (to hoist and dedupe
+packages). That races ZFS's directory-metadata handling and aborts with:
+
+```
+npm error code ENOTEMPTY
+npm error syscall rename
+```
+
+pnpm avoids the problem entirely: it hard-links packages from a global content-addressable
+store instead of renaming directories into place, so it installs cleanly on the same disk.
+
+Notes for contributors:
+
+- Only `npm install` / `npm ci` are affected. Running *scripts* through npm (`npm run build`)
+  still works, because that just spawns tsc/esbuild and installs nothing. Still, prefer `pnpm`
+  everywhere for consistency.
+- The lockfile is `pnpm-lock.yaml` (committed). There is no `package-lock.json`; do not create
+  one.
