Watch published docs for link rot against the Internet Archive

/schedule weekly — outbound link-rot sweep with archived replacements. Setup: add the Wayback Machine MCP server (npx -y mcp-wayback-machine, no API key for reads). Each run, at most 12 turns: 1. Collect every external http(s) link in docs/ and README.md into one list. If the list is empty, report "no external links" and STOP. 2. Request each URL once (HEAD, then GET only on a 405). Never retry a host more than twice and never request the same host more than 10 times in a run — this is a health check, not a crawl. 3. For each link returning 4xx/5xx or failing to resolve, call the Wayback MCP for the newest snapshot before today. Record: original URL, status, snapshot URL, snapshot date. 4. Replace only links that have a snapshot; leave the rest untouched and list them for a human. 5. VERIFY before finishing: re-request every replacement snapshot URL and confirm it returns 200. Drop any replacement that does not. 6. Open a PR with the diff plus a table of every change and every unfixed dead link. EXIT when the PR is open, or when step 1 finds no links, or at 12 turns — whichever comes first. Do not edit link targets that still return 200. Do not push to main. Do not delete a dead link without a working archived replacement; report it instead.
