Capture response headers, body, and transactionId on every check-issue
API call; persist as boa_txn#<ts>#<action> records with 90-day TTL.
Add "Recent BoA Submissions" section to App Home showing the last 10
with click-to-copy transactionId.
Motivation: BoA support asked for a transactionId from a past
successful call and we had no way to recover it from CloudWatch
summary logs alone.
Also adds simulate-csv.cjs (dry-run preview) and stampli-uploader.sh
(launchd-invoked S3 uploader), and gitignores debug artifacts.
- VPC with NAT Gateway for static outbound IP (52.86.95.107) for BoA API
- Payments stored as individual DynamoDB items keyed by check number
- Slack bot token fetched from SSM at runtime instead of CF parameter
- Slack Lambda scans payment items instead of reading single blob
Two Lambda functions:
- processPaymentCsv: S3 trigger, parses CSV, stores dashboard in DynamoDB
- slackAppHome: API Gateway endpoint for Slack events, publishes Home tab view
