## Problem
Failed card charges are never retried, so roughly 2% of invoices stay unpaid until a person notices.
## Recommended Approach
1. Reuse the existing charge path: \`src/billing.ts:4\` exports \`chargeCard(customerId, cents)\`, which the retry job calls unchanged.
2. Refund reversals stay in \`src/ledger.ts\`, which already handles refunds, so the retry job never touches refunds.
3. The job keeps the gateway retry budget as is: \`src/billing.ts:12\` sets \`retries: 5\`.
4. The job lists the commits that touched billing with \`git log --since-commit <sha> -- src/billing.ts\` and posts them to the run log.
5. Capacity: 3 workers each retry 40 invoices per minute, so the job clears 160 invoices per minute, enough for the nightly backlog of 9,000 in under an hour.
## Success criteria
Unpaid invoices from transient failures drop below 0.2% within a month.

\`{"tier": "team", "seat_limit": 25, "sso": false, "price_cents": 1200}\`. One column keeps the diff to a single migration.
- Store each user's editor preferences in a new JSONB column, \`users.ui_prefs\`, for example
\`{"kind": "editor", "theme": "dark", "font_size": 14, "keymap": "vim"}\`. The settings page loads the whole object and saves the whole object; nothing queries or filters on its fields.
## Queries the product needs
- Admin dashboard: list every account whose tier includes SSO.
- Seat enforcement: refuse an invite when the account's member count would pass its seat limit.
- Pricing change: update the price of the team tier for every team account at once.
## Out of scope
Billing provider integration.
