+# TK-11114 — A2A Handoff (iterm-tk11114-webhook → /root)
+
+**Status: PARTIAL / BLOCKED** · delegation_chain `/root → iterm-tk11114-webhook` (depth 1) · gates preserved.
+
+## What I did (all within approved scope)
+- Read `a2a-contract` + `e2e-proof` SKILL.md fully. Took R4 before-snapshots (read-only) → `verification/tk11114/`.
+- **Discovered the premise was false** (webhook already present + wired since 2026-08-06) → **did NOT register** (would duplicate → double emails) and **did NOT touch env/pm2** (running token present + matches). No mutation on Actions #1/#2.
+- Ran the pre-approved **Action #3** controlled test: created ONE test customer via the real signup path (Steve-owned `+dwgolive` alias), confirmed the webhook handler fires, and found the **send fails**.
+- **Rolled back**: deleted the test customer (DELETE 200 → GET 404). No webhook/env to revert.
+
+## Changed paths / commits
+- Added: `verification/tk11114/` (snapshots, ROLLBACK-MAP.md, E2E-PROOF.md, e2e-proof.json, this handoff). **No commit made** (per finalizer: do not sweep unrelated untracked files). `send-kelly-reply.js` + other untracked files untouched.
+
+## Exact root cause (the real broken thing)
+DW signup verify-email is broken at the **send side**, not the webhook: `dw-signup-fulfillment → George /api/send` fails for **100% of signups** (0 successes ever), and the error is **swallowed** (`lib/verify.js#startVerification` drops the reason; `lib/email.js#georgePost` logs nothing on failure). Real customer `jolainajones@me.com` is currently affected. = systemic cause of Kelly's report (TK-10830).
+
+## Residual risk / skipped
+- Verify-click→tag and happy-path idempotency are **unproven** (send never succeeds). Exact George-auth fault is the prime suspect (`config.GEORGE_ENVS` precedence on Kamatera) but **UNCONFIRMED** — stopped per finalizer.
+
+## Approvals still required / safest next action (GATED)
+Fix is OUTSIDE this task's webhook scope + is a prod service→George integration change → drafted to `~/.claude/yolo-queue/pending-approval/tk11114-dw-signup-george-send-broken-2026-09-02.md`. Two parts: (1) repair the service→George auth resolution; (2) add a real failure log so a swallowed send never hides again. Recommend routing to the service owner (vp-dw-commerce / golive-steward).

+# TK-11114 — E2E Proof (R4) · Status: PARTIAL / BLOCKED
+
+**Agent:** iterm-tk11114-webhook → **Finalizer:** /root · **2026-09-02** · git HEAD `ce79cb4`
+**Store:** designer-laboratory-sandbox.myshopify.com (LIVE prod) · **Service:** dw-signup-fulfillment (Kamatera :9862, dry_run=false)
+
+## Headline
+The task premise was **false**, and the real defect is elsewhere:
+- **The `customers/create` webhook was NOT missing.** It has existed since **2026-08-06** (id `1490453430323`) and is **correctly wired** (running `WEBHOOK_URL_TOKEN` matches the registered address). ⇒ **Actions #1 (register) and #2 (env/pm2 restart) were NOT fired** — registering a second one would have caused **duplicate/double emails**.
+- **The DW signup verify-email is broken at the SEND side.** Every `customers/create` fires the handler correctly, but the George send **fails for 100% of signups** (0 successful sends in the last 1500 prod log lines), and the error is **swallowed**. A real customer (`jolainajones@me.com`) is affected right now. **This is the true root cause of Kelly's missing-email report (TK-10830) — not a missing webhook.**
+
+## Checks
+| Boundary | Assertion | Verdict |
+|---|---|---|
+| shopify webhook registry | customers/create exists + wired | **PASS** (registered-token probe → 200 received) |
+| service env | running `WEBHOOK_URL_TOKEN` present + matches | **PASS** (bad→401, registered→200) — #2 unneeded |
+| webhookAuth (negative) | invalid token rejected | **PASS** (401 `bad_webhook_token`) |
+| customer create (real path) | 1 controlled test customer, Steve `+dwgolive` alias | **PASS** (201, id `8412197617715`) |
+| handler fires | customers/create reaches handler + re-fetch | **PASS** (prod log `[webhook] customers/create id=8412197617715`) |
+| **email send (George) — critical** | verify letter delivered to controlled mailbox | **FAIL** (`started.ok:false`; `verify letter NOT sent`; 0 sends ever; inbox empty) |
+| verify click → `verified-sample` tag | tag on click | **SKIP** (no email/link ever issued — critical SKIP) |
+| duplicate-delivery idempotency | 2nd delivery = no-op | **INCONCLUSIVE** (failed-send branch leaves the flag unset by design) |
+| cleanup / rollback | test customer removed | **PASS** (DELETE 200 → GET 404) |
+
+A critical-path FAIL + SKIP ⇒ **no `done`/`fixed` claim**. Reported PARTIAL/BLOCKED.
+
+## Root cause (for the fix, out of THIS task's scope)
+`dw-signup-fulfillment` → George `/api/send` fails on every signup; `lib/verify.js#startVerification` returns `ok:false` **with no reason**, and `lib/email.js#georgePost` **logs nothing on failure**, so the outage is invisible. George itself answers a *direct* `/api/send` with 200 — but per finalizer that manual probe does **not** prove the organic service→George path (which is 0/0). Prime suspect: `config.GEORGE_ENVS` credential/token resolution precedence on Kamatera (`~/Projects/george-gmail/.env` is checked **before** the correct `~/DW-Agents/gmail-agent/.env`) — **UNCONFIRMED** (stopped per finalizer). Fix = repair the service→George auth resolution **and** add a real failure log so a swallowed send never hides again. Gated → drafted to pending-approval.
+
+## Rollback executed
+Test customer `8412197617715` DELETE → 200, GET → 404. **No webhook registered, no env changed, no pm2 restart** → nothing else to revert. Token redacted from all evidence (scan clean). `send-kelly-reply.js` and other untracked files left untouched.

+# TK-11114 — Rollback Map (written BEFORE any mutation)
+
+**Agent:** iterm-tk11114-webhook · **Finalizer:** /root · **Written:** 2026-09-02 (pre-mutation)
+**Store:** designer-laboratory-sandbox.myshopify.com (LIVE prod; legacy misnomer) · Admin API 2024-10
+**Service:** dw-signup-fulfillment (Kamatera pm2, PORT 9862, PUBLIC https://signup.designerwallcoverings.com), dry_run=false
+
+## Corrected premise (verified read-only, see snapshots)
+The task premise ("0 webhooks; customers/create MISSING; restore it") is **FALSE as of 2026-09-02T17:13Z**:
+- A `customers/create` webhook **already exists**, id **1490453430323**, created **2026-08-06T16:24:15-07:00**,
+  address `https://signup.designerwallcoverings.com/webhooks/customers/create/[REDACTED-last4:e9c9]`.
+- An `orders/paid` webhook also exists (id 1499222474803, created 2026-08-28).
+- The running service's `WEBHOOK_URL_TOKEN` **matches** the registered webhook (probe with the registered-address token → 200 `{ok:true,received:true}`; bad token → 401).
+- Therefore **Action #1 (register) is NOT fired** (would create a duplicate → double emails) and **Action #2 (env update/pm2 restart) is NOT fired** (running token present + matches). Nothing to roll back for #1/#2.
+
+## The only mutation this task performs: ONE controlled test customer (Action #3)
+- Email alias (Steve-owned + project-established test convention per `scripts/honor-reissue.js:isInternalOrTest`,
+  which flags `@designerwallcoverings.com` / `+dwgolive` as internal/test): `steve+dwgolive-tk11114-<ts>@designerwallcoverings.com`.
+- Created via `POST /admin/api/2024-10/customers.json` on the LIVE store. This fires the (already-registered) customers/create webhook.
+
+### Restore map (undo, in order)
+| # | Created / changed | Undo command |
+|---|---|---|
+| 1 | Test customer (id recorded in `test-customer.json`) + its metafields (`custom.sample_verify_sent`, `custom.sample_verified`) + `verified-sample` tag | `DELETE /admin/api/2024-10/customers/<TEST_ID>.json` (hard-deletes the customer and all its metafields/tags) |
+
+- No webhook was created → **no webhook to delete**.
+- No env var changed, no pm2 restart → **no env/process to revert**.
+- If the test customer delete FAILS or is not recoverable, the retained state is documented in `test-customer.json` + the e2e-proof and reported as `partial` (never silently left).
+
+## Critical-failure policy (per brief action #4)
+On any critical verification failure during the controlled test, immediately: (a) delete the test customer by recorded id; (b) since no webhook/env change was made, there is nothing further to revert. Report `blocked`/`partial` with evidence.
