One-time script to convert existing annual Member records from the legacy
monthly-equivalent interpretation to cadence-unit. Multiplies
contributionAmount by 12 for billingCadence='annual' members.
Companion to commit 5023fb1 which dropped the server's ×12 on annual
recurringAmount. Must run after deploy, before annual members renew.
Idempotent via a transient `contributionAmountConverted: true` marker
field on each migrated doc — re-runs are safe. Dry-run by default;
`--apply` to write. Skips null/undefined contributionAmount, logs $0
amounts as no-ops.

/**
|
||
* One-time migration: convert Member.contributionAmount from monthly-equivalent
|
||
* to cadence-unit for billingCadence='annual' members. After this migration,
|
||
* an annual member with contributionAmount=180 means "$180/year" (vs the old
|
||
* interpretation "$15/month × 12 = $180/year").
|
||
*
|
||
* Companion to commit 5023fb1 which dropped × 12 from the server's recurringAmount
|
||
* computation. Run AFTER deploying the new server code, BEFORE annual members
|
||
* try to renew or update.
|
||
*
|
||
* IDEMPOTENT via a transient marker field (`contributionAmountConverted: true`).
|
||
* The script only acts on rows where this flag is not set, so re-running is
|
||
* safe — the second run will find 0 unconverted rows.
|
||
*
|
||
* Trade-off: this pollutes the schema with a transient field. A follow-up
|
||
* migration can $unset `contributionAmountConverted` from all docs once every
|
||
* environment is confirmed migrated. The field is harmless if left in place.
|
||
* (Option A from Task 9's plan — chosen because no migration-tracking
|
||
* collection exists in this codebase.)
|
||
*
|
||
* Usage:
|
||
* node scripts/migrate-annual-contribution-to-cadence-unit.cjs # dry-run
|
||
* node scripts/migrate-annual-contribution-to-cadence-unit.cjs --apply # writes
