Verified live: https://table.inkreach.cc/docs-json and /docs → 404
(frontend doesn't proxy swagger paths), while /api/* IS proxied
(PAT auth → 200). Guide now: two-origin table (domain for API calls,
backend origin for swagger), ssh-tunnel fallback for remote machines,
backend-controller grep as last resort; instance-access.md connection
table gains the public-domain row.
git mv rename (history preserved); install.sh + README updated.
The skill is consumed via user-level install (~/.zcode/skills), so
in-repo .agents discovery was unnecessary.
