Drive the next serial sub-PR of the Groww second-feed plan end-to-end (sync → review → implement → gate → PR → auto-merge → monitor).

Verify NSE F&O / Dhan / SEBI / Indian regulatory facts (rates, lot sizes, freeze limits, STT, brokerage, rate limits) against authoritative sources. Slash-command only (`/nse-fact-checker`). Trigger BEFORE adding or modifying any RATE/LIMIT/REGULATORY constant whose value comes from an external authority — typically items in the "Recommended trigger surface" section below. Skip for pure protocol constants (packet offsets, DEDUP keys) — those are covered by existing ratchet tests.

Run full quality gates — all 8 checks matching CI plus local-only gates
