(a) `--to does-not-exist` (unknown node) emitted `{\"path\": [], \"found\": false, \"reason\": \"No path from 'authentication' to 'does-not-exist' within 6 hops — either the target is unknown, unreachable from the source, or the shortest path exceeds --max-hops.\"}` (outputs/no-path-unknown.json). (b) `--to quarantined-feature` (isolated node) emitted the equivalent envelope with the same shape (outputs/no-path-isolated.json). Neither output is a bare `[]` and neither is a stack trace — both are structured JSON with `found: false` and a non-empty human-readable `reason` sentence. This was the previously-failing expectation; commit 4936536 in skills/doc-wiki/scripts/graph_ops.ts adds the empty-case envelope and it now passes."
