Stacked on #2447. Part of the audit stack that starts at #2434.

Small follow-ups the earlier layers left in files they did not own.

• MAPLE_DB_URL is gone. The module that turned it into a PGlite data directory was removed in fix: audit first pass (rollup hour bounds, apdex errors, fetch capture, Tinybird 429 retry) #2434, the Env field had no reader, and docs/persistence.md and .env.example still described a persistent local PGlite. Tests and evals use PGlite in memory and need no setting.
• CLAUDE.md and AGENTS.md named SubagentHost, which does not exist in the source. The review fan-out uses Subagent from @yielded/agent/subagent.
• Comments and docs that pointed at things removed lower in the stack: nginx.conf, the compose build of the scraper image, the renamedFrom shims, alert-templates/, and a generated route tree the formatter config still mentioned.
• .env.example said Llm.ts lives in apps/api. It is in apps/ai.

Verification

• packages/backend typecheck is clean after removing the Env field. Lint is clean on the two code files.

Deliberately untouched

• Root app.json, TODO.md, the tracked .context/ directory, doctor.config.json and the react-doctor skills. These look like leftovers but are yours to decide.
• lib/semconv, which nothing imports.
• docs/browser-sdk.md, an older copy of the landing docs page.

Maple review

🟢 Confidence 10/10 · safe to merge. Comment and doc-string cleanup plus one dead Env field; a full-tree grep confirms nothing reads MAPLE_DB_URL at the head.
_{no findings · tests not needed · risk low}

Removes the reader-less MAPLE_DB_URL from Env and .env.example and corrects stale comments (scraper Dockerfile, nginx.conf, routeTree.gen.ts, Llm.ts path). Every claim holds against the head tree; safe to merge.

Before merge

• Infra · Check every environment has what this config now expects · apps/scraper/Dockerfile

_{2b4c920 · What was checked, coverage and telemetry details are on the Maple / review check. Reply "won't fix" to dismiss a finding, or mention @maple-review-bot to ask about one.}

Merged with 1 step from "Before merge" still open. If it is done, tick it on the review comment; if not, now is the time.
