- 0008 — Modified Dietz: justifies the choice over ROI / TWR / IRR;
references commands/return_calculator.rs and the 7 TDD cases.
- 0009 — Proxy price-fetching via maximus-api: documents the privacy
proxy architecture (header stripping, no log correlation, fixed
simpl-resultat UA), the Yahoo + CoinGecko adapter abstraction, the
Bearer activation_token auth strategy, the rate limiting (client

BLOCKED in #143; this ADR documents the agreed-upon design.
- 0010 — FK ON DELETE RESTRICT on balance_account_transfers
.transaction_id: justifies the integrity-over-friction trade-off
for Modified Dietz reproducibility.
