Tribal Knowledge — RDS Connection Pool Limits (HIGH):
The shared RDS instance has a hard limit of 150 connections divided across 4 services: Alpha API (50), Beta Analytics (30), Internal Tools (20), Migration Worker (50), with 10 reserved for DBA access. Do NOT increase max_connections — the db.r5.large instance cannot handle more without upgrading.

Tribal Knowledge — Batch Size for Data Migration (HIGH):
BATCH_SIZE must stay at 500 for the migration worker. Jane tested 1,000 and 2,000 in staging — both caused OOM kills on the t3.medium worker nodes.

GAP-001: Staging Environment Setup Guide — HIGH
Jane shared staging gotchas in Slack but committed to writing a formal guide "this sprint" — never created. New engineers will hit 2-3 day delays.

GAP-002: Alpha Cutover Rollback Decision Tree — HIGH
Runbook covers happy-path rollback but not partial failure scenarios. Partial cutover failure without decision tree could cause 4-8 hour outage.
