[P2][bug] 3 SDK methods call routes that do not exist (live 404)

[karlwaldman]

Problem

The SDK calls 3 paths that have no route in the API. Every call returns 404.

Source	Path called	Live
src/resources/drilling.ts:321	/v1/drilling-intelligence/trends	404
src/resources/drilling.ts:483	/v1/drilling-intelligence/basin/{name}	no route in rails routes
src/resources/futures.ts:662	/v1/futures/spreads	404

Checked on origin/main f8c5414 against rails routes (api b64093719), swagger.json and openapi_route_policy.yml. Live 404s confirmed 2026-10-03 with the test key.

Fix

• Repoint to the canonical routes or remove the methods (with a deprecation in the next minor).
• Add a contract test: every SDK path must appear in the API's swagger.json or the compat allowlist.

Related hygiene

• @types/node and @types/ws ship as runtime dependencies; move them to devDependencies.
• Dependabot chore(deps-dev): bump markdown-it from 14.3.0 to 14.3.2 #124 fails npm audit on fast-uri GHSA-hrr3-gc8f-f4qj (fixed in 3.1.8). main shares the lockfile and has had no push CI since 09-14.

Status: confirmed live, 2026-10-03.
