 3. `lib/tests/mods.test.sh` passes on the repo, fails on a fixture that lacks the loading link, fails on an empty `mods/`, and SKIPs (exit 0) the CLI checks when `claude plugin test` is unavailable (probe by capability, PATH-shadowed `claude` in the control).

 4. `doctor.sh` prints a `── Mods ──` section with a ✓ line for model-router; with the link absent (HOME pointed at a scratch `.claude` whose `skills/` lacks the link) the section prints an info line, doctor reaches its summary and exits 0 for that section's sake (no new error).

 7. Judged by reading: no change to settings.json, link.sh or any install script; the suite probes the CAPABILITY (`claude plugin test --help`), bounds every CLI call in time, captures `2>&1`, SKIPs with a reason, fails when no mod is found; doctor's section is fail-soft under `set -euo pipefail` (existence test before readlink, `-ef` comparison, one guarded `claude plugin list --json`, python exits 0 with `unknown` on any parse error), never increments `_LINK_PASS`, says "enabled" not "loaded", treats a missing link as info; the link step is idempotent; CLAUDE.md names the per-machine `"enabled": false` switch, the tracked-settings cost of `enabledPlugins`, and the dev-copy shadowing rule; the CLAUDE.md section is terse English matching the file's style.
 Q (r2): ordering / A: this contract runs after the floor contract (`2026-10-08-model-router-floor-1835`) is committed and green. [orchestrator]
 Q (r2): update-all `claude plugin update` over `@skills-dir` / A: accepted residual (one recurring warn), logged in TODO; out of FILE SCOPE. [orchestrator]
