+# TK-11114 — Backfill CONFIRMED sent · 2026-09-02
+
+Steve ran the gated backfill (`env -u GEORGE_BASIC_AUTH DRY_RUN=0 node backfill-send.js --apply` on Kamatera).
+
+**Result:** `DONE: would/sent=68 sent=68 skipped=0 failed=0` — every one `[email] sent via George: status=200`.
+Independently confirmed in the steve-office Gmail **Sent** folder (12:15–12:17 PM PT burst, 68 messages,
+subject "Confirm your email — your 3 complimentary samples are ready 🎁", from steve@designerwallcoverings.com).
+
+- Scope: the 68 genuine retail signups since go-live (2026-08-28) that never got the verify letter
+  during the outage (test/internal + trade excluded).
+- Each customer's `custom.sample_verify_sent` flag is now set, and every send is ledgered
+  (`backfill-ledger.jsonl` on Kamatera) → idempotent; re-running sends nothing.
+- Delivery to each external inbox is beyond local verification; "George status=200 + present in Sent" is
+  the confirmation. Any hard bounces would surface in the steve-office inbox.
+
+## TK-11114 — fully closed
+1. Root cause corrected (send-side, not a missing webhook). ✅
+2. Send fixed + proven E2E + negative 401. ✅
+3. Durable / restart-safe (ecosystem DRY_RUN=0 + .env token e9c9 + pm2 save). ✅
+4. Backfill of the 68 missed signups sent. ✅
+
+**Residual (minor / separate):**
+- Idempotency is eventual (same-instant double-delivery can double-send) — optional hardening, low severity.
+- Kelly (kcyounge@gmail.com, TK-10830) was NOT in this window's list (a different `kc***@msn.com` was) — her
+  case stays under TK-10830's dedicated honor path.
+- Window was go-live (2026-08-28); earlier signups were dry-run/gift-card-era (handled by honor-reissue.js).
