The demo seeder created bills + categories only, so nearly every page
rendered empty; clear-demo had a data-loss bug and error-protection gaps.
Seed now populates every user-facing surface: bills with autopay states,
3-6 months of payment history (with drift + debt paydown), monthly
skips/overrides/snoozes/notes, a demo bank source + accounts + matched/
unmatched/subscription transactions, categorised spending + budgets +
rules, planning income/starting-amounts, category groups, an active
snowball plan (+ extra-payment), merchant rules, and a calendar feed —
so a new user can explore Tracker (incl. overdue/drift), Analytics,
Summary, Spending, Snowball, Payoff, Transactions, Matches, Subscriptions,
Banking and Calendar with realistic data.
Correct removal (the emphasis):
- Migration v1.07 adds an is_seeded marker to the 12 user-scoped,
non-cascading demo tables (bill-children cascade with their seeded bill).
- clearSeededDemoData() (new, in userDataService alongside eraseUserData)
removes ONLY seeded rows in one transaction, child->parent, and keeps a
seeded category if a user's own bill still references it.
- Fixes the category collision: seed marks ONLY categories it creates, so
clear no longer deletes the user's default categories / uncategorises
their real bills.
Error protection: idempotency guard on seeded (not all) bills -> 409
instead of a fake "created 0"; whole seed wrapped in one transaction
(atomic); rate-limit + audit + standardizeError on all three routes;
seeded-status reports payments/transactions counts; dead --force removed.
Client copy/counts corrected.
Verified: typecheck/check clean; server suite 232/232 (+6 new); client
typecheck/lint/build clean; e2e probe 17/17; on a COPY of the real prod
DB the v1.07 migration applies (integrity ok) and a seed->clear round-trip
on the data-rich user restores their real data byte-for-byte with no
orphans.
