chore(memory): job8 C — darwin-skill reinstalled full pinned tree, detached HEAD

BDR-058 + LRN-109. Root cause of the "referenced files absent" finding: the skills CLI's skillPath only fetches SKILL.md, never sibling references/scripts/templates dirs. Upstream HEAD matched the already- recorded lockfile hash exactly (no drift, no tamper) — reinstalled the full tree at that pinned SHA, detached HEAD so nothing can silently advance. Reinstall happened outside this repo (~/.agents); this commit is the only repo-side record. Backup of the old single-file dir kept.

 - **context**: `lib/toggle-external.sh:191` had this exact double-quoted form since BDR-025/026; it materialized the key into `~/.claude.json` (2026-07-02 incident) and kept re-leaking into every native auto-backup taken afterward (5-file rotating ring buffer, plaintext each time) until fixed at the source.
 - **future application**: adding ANY MCP server with a secret via `claude mcp add --env`, single-quote the value using `${VAR}` syntax, never double-quote/bash-expand it. The var still has to exist in the environment of the process that starts `claude` — don't solve that with a blanket `export` in `~/.bashrc` (broadens exposure to every subprocess); scope it with a wrapper function that sources the secret into a subshell before `exec`ing the real binary (see `~/.bashrc`'s `claude()` function, [[BDR-057]]).

+## LRN-109 — `skills` CLI (vercel-labs/skills) fetches only `skillPath`, not sibling refs/scripts/templates
+
+- **context**: job8 audit flagged darwin-skill NOT-CLEAN — SKILL.md references `references/*.md`, `scripts/*.mjs`, `templates/*.html`, all absent on disk. Traced to `~/.agents/.skill-lock.json`: `skillPath: "SKILL.md"` — installer fetched that ONE file, never the sibling dirs the skill text points to. Upstream repo (public clone, verified) had them all at the exact commit already recorded (`skillFolderHash` matches) — not drift, an installer-scope gap.
+- **future application**: any skill installed via `skills` CLI whose SKILL.md references relative paths needs a post-install check those paths exist on disk — `skillFolderHash` only hashes what WAS fetched, says nothing about what's missing. If absent: clone source repo at the recorded hash, copy full tree in, keep `.git` detached (cheap real pin, beats trusting the CLI's opaque hash alone).
+- **cousin**: [[BDR-058]] (this job's fix), darwin-skill's OVERSCOPED git-commit finding (job8 report — 3rd-party code, not patched, accepted risk under human-checkpoint gating, twin of [[LRN-105]]'s no-execute mandate for OUR read-only audits).
