On a fast local disk pnpm's content-addressed store typically wins on cold/warm installs and, especially, on **disk footprint** across multiple checkouts (one global store hardlinked into every `node_modules` vs Yarn copying ~279 MB per worktree — some devs regularly keep ~10 or more worktrees for this repo). That dedup advantage did **not** show in the migration-time numbers above because the test store and `node_modules` sat on different filesystems, defeating hardlinks; on a single-filesystem dev box or CI cache it applies. The honest summary: install speed on our NFS dev filesystem is a wash within noise; the move is justified by ecosystem alignment, phantom-dependency safety, and cross-checkout disk dedup — not by a raw install-time win.
All quality gates (constraints, typecheck, lint, doc-sync, test:coverage at 100%, build, knip, publint, echo-agent demo smoke) pass unchanged on pnpm, which is the correctness proof that the linker swap introduced no phantom-dependency breakage.

Two Node features gate the source runtime:
- **`node:sqlite`** — `packages/session-persistence/session-persistence-sqlite` does a top-level `import { DatabaseSync } from 'node:sqlite'`. The module dropped its `--experimental-sqlite` flag requirement at **22.13** (LTS) and **23.4** (Current); before those, importing it throws at load.
- **Native TypeScript type-stripping** — the `packages/examples/stdio-demo/tests/built-bin.e2e.ts` smoke boots the published `lib/bin.js` under plain `node` (no tsx) and loads the example's `.ts` plugins (`mock-llm.ts`, `echo-tool.ts`). Type-stripping is the default from **22.18** (LTS) and **23.6** (Current); before those it needs `--experimental-strip-types`.
- **Native TypeScript type-stripping** — the built-mode `examples/headless-agent/tests/keyless-smoke.e2e.ts` smoke boots `dsh-cli-demo`'s published `lib/bin.js` under plain `node` (no tsx) and loads the example's `.ts` test adapter (`cli-mock-llm.ts`). Type-stripping is the default from **22.18** (LTS) and **23.6** (Current); before those it needs `--experimental-strip-types`.
Those source features clear on the 22.x line at **22.18**, but the installed Pi adapter dependency raises the advertised LTS floor. `@deepseek-ai/dsh-llm-pi-ai` depends on `@earendil-works/pi-ai@0.79.3`, whose package declares `engines.node >=22.19.0`, so the LTS floor is **22.19**. The 24.x branch remains `>=24.0.0`. The disjoint range excludes Node 23 entirely: Node 23.023.5 still has at least one flagged source feature, and the 23 line is non-LTS/EOL, so advertising `>=23.6` would add a dead release line and a CI leg no deployment should use.
