If recovery+sleep+cycle all fail but workout succeeds, the function returns `{recovery: null, sleep: null, strain: null, summary: \"No data available yet today\"}`. This is useless because workout data only surfaces inside the strain block (which requires cycle). Violates the spec: \"If ALL endpoints fail, throws error (not partial emp",

A `Record<ClientTarget, () => string>` lookup would remove the duplication.\n\n**Fix:** Optional refactor — map each printed-command target to its generator and emit once.

Pasting it records the secret in shell history.

The Copilot path embeds creds via `JSON.stringify` then shell-quotes the whole payload, so the strongest proof is a round-trip: unwrap the shell single-quoting, `JSON.parse`, and assert the apostrophe-containing secret survives both layers intact.\n\n**Fix:**\n```ts\nconst inner = cmd.slice(cmd.indexOf(\"'\") + 1, cmd.lastIndexOf(\"'\n\n[Read the thread](https://github.com/shashankswe2020-ux/whoop-mcp/issues/179) · 2026-06-13 · open · 0 comments\n\n### Document getOrFetch undefined-value conflation assumption\n\n**Source:** code-review-checkpoint-13, Nit #1\n\n**Problem:** `src/cache/memory-cache.ts:148-151` — `get()` returns `undefined` for both an absent key and a stored `undefined` value, so a fetcher that legitimately resolves to `undefined` would never cache-hit.

A `getOrFetch(key)` issued after `clear()` but before the pre-clear fetch settles hits the still-present in-flight entry and resolves with the pre-clear value (returned once, not cached thanks to the generation guard).
