A reminder campaign is a deep-copy of its parent's non-clicked
recipients with NEW gift_tokens. Clicks on the reminder were flagging
the CHILD recipient's gift_link_clicked but the parent campaign's
counters never updated — operators had to check two campaigns to see
the cumulative click rate.
Hub:
- New cascadeClickToParent() helper — when a recipient with
parent_campaign_id is flagged as gift_link_clicked, mirror the flag
+ timestamp onto parent.recipients[parent_row_index] and broadcast
a recipient-update SSE event so the parent's open page refreshes
live. Adds a gift_clicked_via_reminder breadcrumb (the child
campaign id) so the parent UI can show "↩ via la relance XXX".
Idempotent — already-clicked rows are no-op.
- Three cascade call sites: applyWebhookEvent fast path (CustomID),
applyWebhookEvent fallback (msgId scan), handleGiftRedirect wrapper.
- handleGiftRedirect also now sets gift_link_clicked=true on first
successful redirect (Mailjet webhook can lag or drop; the wrapper
redirect is the most reliable click signal we have).
- GET /campaigns/:id now attaches a "reminders" array with summary
counters for every reminder child of the campaign.
Ops UI:
- "Cette campagne est une relance" banner on child detail pages with
a back-link to the parent.
- "N relance(s) envoyée(s)" banner on parent detail pages with
clickable chips showing each child's gift_clicked/total ratio.
- Recipient table: 🔁 icon next to the gift-click indicator when the
click came via reminder, plus a "↩ via la relance XXX" line in the
tooltip so the operator can trace the engagement channel.
One-time backfill applied on prod to mirror clicks that happened
between reminder send and this deploy (1 click cascaded —
cmp-20260522-2d4605 gift_clicked 27 → 28).
