Production OOM triage: every 'Worker exceeded memory limit' burst hits unrelated cheap routes right after a deploy — the 128MB limit is per isolate, and the main worker's eagerly-evaluated module graph is what crowds it, not any single request. - Alias just-bash to a throwing stub (worker never uses it): removes just-bash + turndown + @mixmark-io/domino from the bundle. The chain was pulled in eagerly by @cloudflare/think via the SamChatAgent re-export in src/server.ts; SAM only uses its own MCP tools. - Disable Think's workspace bash tool on SamChatAgent so the stub is unreachable at runtime. - Dynamic-import page-analyzer (cheerio) in the site-audit crawl step so it evaluates only when an audit runs, not in every isolate. - Drop the turndown CJS alias workaround (#339): turndown is no longer in the graph at all. Main eager server chunk: 14,434 kB -> 11,712 kB (-19%); cheerio's 503 kB now a lazy chunk.
