Books And Records

Summary

If you're building or auditing recordkeeping systems for broker-dealers or investment advisers, this walks you through SEC Rules 17a-3, 17a-4, and 204-2 requirements. It covers what records you must create (order tickets, blotters, customer complaints), how long to keep them (six years for ledgers, three years for communications, life of firm for incorporation docs), and storage standards like WORM compliance for electronic archives. Useful when you're setting up email archiving, responding to exam requests, evaluating vendor migrations, or figuring out retention schedules. The retention tiers are clearly laid out, and it addresses modern headaches like social media capture and BYOD policies. Strong on the technical storage requirements and the two-year easily accessible rule.

inertia-rails-controllers

inertia-rails/skills

ALWAYS `render inertia: { key: data }` to pass data as props — instance variables are NOT auto-passed (only alba-inertia does that). Rails controller patterns for Inertia.js: render inertia, prop types (defer, optional, merge, scroll), shared data, flash, PRG redirects, validation errors. Use when writing controllers that load data, display records, or serve Inertia responses. CRITICAL: external URLs (Stripe/OAuth) MUST use inertia_location, NEVER redirect_to.
