T013 worker found record_install violating CHECK(amount>0) when platform_pct
rounds cut or seller_amount to zero (unhandled IntegrityError -> HTTP 500).
Fixed: skip zero rows, grant references the paying tx; regression test added.
9 ledger tests green.

Verified on master: 14 tests green (schemas+cli+indexer); ledger API exercised
end-to-end via TestClient (grant admin-only, install 200/409/402, refund
restores balance, auth 401); adapter factory resolves local + raises
RailsNotLanded on the stub.

Rail-independence is the plan's spine: fedlearn rails verified NOT landed
(no m2/m2-core, no capture/curator CLIs), so the wedge builds against frozen
interfaces — m2/market-registry as registry of record, ApplyAdapter seam with
local adapter now / m2core-sync stub, schemas frozen here with a fedlearn
coordination note. Constitution check passed (1 justified deviation).
