Changelog

2026-09-23 deploy

C-1: request logging switched to JSON lines (src/request-log.js). Log volume and format only; no request-handling behavior changed.
C-2: totals computation refactored for readability (src/totals.js). The old cents-as-integers helper was replaced with a direct decimal expression that reviewers found easier to follow. No behavior change intended.
C-3: inventory client timeout raised from 2s to 5s (src/inventory-client.js). Reduces spurious failures when the inventory service is slow.
