Dogfooding `/config-audit plugin-health` against a fasit registered before the
run: 11 of 12 predictions confirmed, 1 refuted with evidence, 0 deviations.
The command's default path could not produce the report it documents.
M-BUG-21 (third arm): the argument loop ended in
`else if (!args[i].startsWith('-')) targetPath = args[i]` with no unknown-flag
branch, so `--output-file /tmp/x.json` was dropped and its value became the scan
target. Worse than in drift-cli: a non-existent path discovers no plugins, so the
scanner answered "No plugins found" (info) with exit 0 — a reassuring answer, not
an error. Unknown options and a value-less `--output-file` now exit 3.
M-BUG-33: the scanner had no `--output-file` and its default-mode report goes to
stderr, which `commands/plugin-health.md` discards with `2>/dev/null` before
telling the agent to read stdout. Zero bytes captured.
M-BUG-34: per-plugin rows and the grade formula never left `scan()` — the only
grade code, `formatPluginHealthReport`, had no caller — and cross-plugin findings
were flattened behind a `category` they share with per-plugin findings. The
mandated table and Cross-Plugin section were unbuildable, so the command had to
fabricate them. `scanDetailed()` now returns them; `scan()`'s frozen v5.0.0
envelope is unchanged by construction.
M-BUG-35: `.claude-plugin/marketplace.json` was flagged as an unknown file. It is
the documented catalog location, and `"source": "./"` makes the repo root its own
plugin, so one `.claude-plugin/` legitimately holds both.
Also: `commands/posture.md` ran both optional scanners in default mode under
`2>/dev/null` and read stdout — the same class as feature-gap.md:133 in the fix
chunk. A CLI-side flag fix does not close its callers.
Tests 1420 -> 1432, red first. Frozen v5.0.0 snapshots untouched.
