This repository contains the SCCCC membership management code.

The expiration processing is split into two parts:

• Generator (pure JS, tested): Manager.generateExpiringMembersList — inspects ActiveMembers and ExpirySchedule and returns an array of human-friendly messages (no side-effects). These messages are persisted by the GAS wrapper into the ExpirationFIFO sheet.
• Consumer (pure JS, tested): Manager.processExpiredMembers(expiredMembers, sendEmailFun, groupRemoveFun, opts) — accepts a batch of expired items and applies side-effects via injected functions. It returns an object with:
  • processed: number of items successfully completed
  • failed: minimal, human-friendly array of failed items (stable shape used by tests/logging). Each failed object: { email, subject, htmlBody, groups, attempts, lastError }.
  • failedMeta: machine-friendly array containing retry bookkeeping for persistence by the GAS wrapper. Each meta object: { __fifoId?, id?, attempts, lastAttemptAt (ISO), lastError, nextRetryAt (ISO or ''), dead (boolean) }.

Notes:

• Manager is authoritative for retry/backoff decisions. The GAS wrapper should persist failedMeta into the FIFO and move items to the dead-letter sheet when dead is true.
• The wrapper is responsible only for GAS operations (sheet I/O, triggers, MailApp/AdminDirectory). Business logic remains in the pure-JS Manager for testability.
