Summary

Makes /admin/trade the system of record for the entire trade relationship: lead → email conversation → replies → notes/status/follow-ups → full history. Admins send customer email from the lead workspace, inbound replies and forwarded mail attach to the right lead automatically, and the existing inquiry notification email stays as a safety net.

Closes #152

Changes

  • Outbound email — POST /api/admin/trade-leads/[id]/messages (admin-authed) sends via Resend to the lead's stored address only (the endpoint cannot be used as a mail relay); the send is recorded before dispatch so a provider failure is recorded honestly, not hidden. Composer UI lives in the lead's Email section, with a Reply action on inbound messages that seeds real In-Reply-To/References threading.
  • Inbound routing — every lead gets an opaque 8-char Crockford replyToken (never the Firestore id) forming <token>@<configured inbound domain>. Production uses the inbound domain configured in Resend via TRADE_REPLY_DOMAIN; we are not using @reply.deepdivebrewing.com as the production address. Tokens are backfilled lazily on first detail view / first send without touching retention anchors. The workspace shows a copyable "Attach email to this lead" address for forwarding outside mail into the history.
  • Resend webhook — POST /api/webhooks/resend verifies the svix signature on the raw body before parsing (401 on invalid), resolves the lead by routing token, dedupes inbound mail by provider email id (inb_<id> doc), converts inbound HTML to plain text (raw inbound HTML is never rendered), truncates oversized bodies, and returns 500 on transient failures so Resend retries. Unknown tokens fail safe and create nothing.
  • Threading — RFC Message-ID on every outbound message; inbound correlation matches In-Reply-To/References against stored message ids, with the routing token as lead-level fallback; a lead can hold multiple threads.
  • Delivery state — email.delivered/.bounced/.delivery_delayed/.complained/.failed callbacks advance the communication's state monotonically inside a transaction (replays and concurrent events never regress it); a communications collection-group single-field index on providerEmailId supports the lookup.
  • Staff notifications — new inquiries send a blanket alert to TRADE_NOTIFICATION_EMAIL (legacy TRADE_INQUIRY_TO_EMAIL still works) linking directly to the lead; customer replies notify the assigned owner's active admin email, falling back to the shared mailbox when unassigned. Notification mail is a separate channel — never recorded as lead communication.
  • Communications storage — full records in tradeLeads/{id}/communications (bodies, headers, provider ids, attachment metadata); the activities timeline carries a compact communication summary referencing the record. Firestore rules deny client access to both subcollections.
  • Island field — first-class island using the canonical venue-island vocabulary (saba/sxm/statia + St. Kitts, Nevis, Anguilla, Other): public /trade form select, manual create, list badges, detail header, island filter with an explicit "not set" option. Old leads stay unset — never silently reclassified.
  • Phone normalization — lib/phone.ts parses human input to E.164 where confident (+/00 international, 7-digit Saba locals → +599, NANP); raw value preserved, phoneNormalized stored on new leads, tel: from E.164 or raw digits, wa.me only when valid, and old records get improved display via normalize-on-read (no migration).
  • Retention — scripts/prune-trade-leads.ts now sweeps both activities and communications in bounded batches; inbound/outbound email counts as meaningful activity, viewing does not.
  • Docs — docs/admin/trade-inquiries.md (usage + full Resend/DNS setup), docs/TECHNICAL.md, operations docs (deployment env vars, credential rotation for the webhook secret, observability events), .env.local.example.

Verification

  • npm ci
  • npm run check:react-versions
  • npx tsc --noEmit
  • npm run lint
  • npm test — 480 tests pass (new suites: phone.test.ts, trade-leads-email.test.ts; expanded admin/rules/trade-lead coverage)
  • npm run test:rules — 32 emulator tests pass, incl. new communications deny-all
  • npm run build — clean; new routes /api/admin/trade-leads/[id]/messages, /api/webhooks/resend
  • npx playwright test — 135 smoke tests pass, incl. new axe coverage of the composer/inbound timeline and a composer send-path test
  • npm run check:md-links

Risk / deployment notes

New environment variables (all server-only):

Variable Scope Required
RESEND_WEBHOOK_SECRET Production Yes — endpoint refuses all events without it
TRADE_NOTIFICATION_EMAIL Production Recommended — falls back to TRADE_INQUIRY_TO_EMAIL
TRADE_FROM_EMAIL Production Optional — falls back to RESEND_FROM_EMAIL, then trade@mail.deepdivebrewing.com
TRADE_REPLY_DOMAIN Production Set explicitly to the Resend inbound domain used for trade replies. The code fallback is reply.deepdivebrewing.com, but that is not the production address.

Deployment requirements: configure the chosen trade-reply domain for inbound email in Resend (MX records), set TRADE_REPLY_DOMAIN explicitly to that domain in Production, add a webhook at /api/webhooks/resend subscribed to email.received + the email.* delivery events, and deploy firestore.indexes.json (the new communications collection-group override on providerEmailId). Production is not intended to use reply.deepdivebrewing.com. Full steps in docs/admin/trade-inquiries.md.

  • No secrets, credentials, or private data were committed.
  • Inbound email bodies are stored as plain text only and truncated at 60 KB; attachment content is not ingested (metadata only — documented follow-up).
  • Inbound creates a new external ingress path: signature verification is the trust boundary, unknown tokens are ignored, and nothing can be written by clients (rules deny all).

Summary by Sourcery

Make the admin trade workspace the system of record for lead email conversations while adding island classification and safer phone handling.

New Features:

  • Add end-to-end email conversations to trade leads, including admin sending, inbound reply routing, threading, delivery tracking, and staff notifications.
  • Add island capture, filtering, and history to trade leads while preserving unset values for existing records.
  • Normalize trade lead phone numbers for improved display, telephone links, and safe WhatsApp links.

Bug Fixes:

  • Prevent unverified or unknown inbound email from creating lead records and ensure webhook retries and delivery callbacks are handled safely.
  • Extend trade-lead retention cleanup to remove both activity and communication history.

Enhancements:

  • Store complete email communications separately from compact activity timeline entries and restrict both subcollections to server-side access.
  • Improve trade inquiry notifications with direct lead links and support configurable sender, notification, reply-domain, and webhook settings.
  • Add idempotent outbound email retries and conservative normalization behavior for legacy phone records.

Deployment:

  • Document Resend inbound-domain, webhook, environment-variable, index, and credential-rotation requirements for the email pipeline.

Documentation:

  • Document the trade email workflow, island and phone fields, notification behavior, retention handling, and operational setup.

Tests:

  • Add coverage for phone normalization, email routing and threading, delivery state progression, webhook safeguards, island handling, communication access rules, and the admin email composer.

Summary by CodeRabbit

  • New Features

📝 Walkthrough

Walkthrough

The trade-lead workflow adds island and phone handling, outbound and inbound email, per-lead reply routing, and delivery-state updates. Admin routes and the workspace expose communication records. Firestore rules, indexes, pruning, tests, and operational documentation cover the new data and workflows.

Changes

Trade lead management and email

Layer / File(s) Summary
Island and phone data flow
lib/trade-leads-common.ts, lib/trade-leads-admin-common.ts, lib/trade-leads-admin.ts, lib/trade-leads.ts, lib/phone.ts, components/trade-inquiry-form.tsx, components/admin-trade-workspace.tsx, tests/lib/phone.test.ts, tests/lib/trade-leads.test.ts, tests/lib/trade-leads-admin.test.ts
Public and manual lead forms accept canonical island values. Admin lead records store island changes and normalized phone numbers when available. The workspace displays and filters islands and uses shared phone-link helpers.
Email records and processing
lib/trade-leads-email-common.ts, lib/trade-leads-email.ts, lib/resend-config.ts, lib/trade-leads.ts, tests/lib/trade-leads-email.test.ts, .env.local.example, docs/operations/*
Shared helpers define reply tokens, message validation, threading, communication views, and delivery-state ordering. The server pipeline sends outbound messages, processes signed inbound events, records communications, notifies staff, and applies delivery updates. Configuration and operations references describe the related settings and events.
Admin routes and communication storage
app/api/admin/trade-leads/[id]/*, app/api/webhooks/resend/route.ts, lib/trade-leads-admin.ts, firestore.rules, firestore.indexes.json, scripts/prune-trade-leads.ts, rules-tests/firestore.rules.test.ts, tests/security-rules.test.ts
Lead detail responses include communications. The message route sends admin-authorized email, and the webhook route verifies events before dispatch. Firestore denies client access to communications, the index supports provider-email lookups, and pruning removes communication records with activities.
Admin workspace and workflow documentation
components/admin-trade-workspace.tsx, smoke-tests/admin-accessibility.spec.ts, docs/TECHNICAL.md, docs/admin/trade-inquiries.md
The workspace displays communication details and delivery states, provides a message composer and inbound-address copy control, and supports replies linked to existing communications. Documentation and smoke tests describe and exercise the updated trade-lead and email workflows.

Priority: ➖ Normal

Merge Risk: 🟡 Moderate · up to 9ec9e

Repeated retries could send a customer the same email twice. Preserve the original queued-send timestamp before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 9ec9e

Access controls limit exposure, but repeated recovery attempts can exceed duplicate-send protection, and interrupted deletion can leave confidential email history behind.

Retained concerns

  • Medium · security · inferred: Deleting a lead commits before its history is swept. Cleanup failure or interruption can therefore leave newly persisted confidential email records without a parent. Subsequent pruning enumerates surviving lead documents and cannot rediscover these records automatically. The parent-first pattern existed for activities before this PR; the change extends that failure exposure to full email history. Client access remains denied, and the script requests manual cleanup, limiting access but not guaranteeing retention completion.
  • Medium · reliability · inferred: Queued recovery reuses the communication ID as the provider idempotency key but overwrites sendAttemptAt on each retry. For example, unsuccessful recovery at hour 22 can permit another dispatch at hour 44 relative to the first attempt. This exceeds the repository-stated 24-hour provider protection horizon and weakens containment of an uncertain accepted send. Administrator authorization, identical subject/body checks, and an already-sent short circuit limit reachability; an actual duplicate remains dependent on provider behavior after key expiry.
Security review details

Security Blast Radius

  • inferred — Someone possessing a valid routing address can submit email content to its resolved lead and advance that lead's retention anchor. The signature authenticates the provider callback, not the customer's identity. Each processed inbound event selects one existing lead; unmatched tokens create nothing. Privileged retention operations, by contrast, enumerate the configured trade-lead collection.

Security Findings and Attack Paths

  • inferred — The supported privacy failure path requires cleanup failure or interruption, not an authentication bypass: a lead is deleted, remaining communication batches are not completed, and later parent-based pruning misses the confidential records. Direct client reads remain denied, so the concern is incomplete erasure and retained privileged-access exposure rather than public disclosure.

Trust Boundaries and Controls

  • observed — Outbound sending calls requireAdminActor before entering the email domain operation. That guard invokes token verification, administrator assertion, and active-actor resolution. Initial sends derive their sole recipient from the stored lead email; reply and retry identifiers are resolved under the same lead.
  • observed — The webhook verifies the raw payload with the configured signing secret before dispatching an event. Invalid or unverifiable requests receive 401. This is separate from inbound sender identity and lead-level routing.

Resilience and Maintainability Implications

  • observed — Recovery retains the communication identity and checks saved subject/body equality. A stored providerEmailId avoids another dispatch; transport failure preserves queued uncertainty. Inbound duplicate records are rejected transactionally, and matched delivery callbacks advance state transactionally by rank. These controls reduce repetition and concurrency risk but do not close the rolling retry horizon or interrupted-erasure gaps.

Hardening Proposals

  • proposed — Anchor uncertain-send recovery to an immutable first-dispatch timestamp for each idempotency key, separate from the latest attempt timestamp. Refuse replay beyond the provider's confirmed protection horizon, including when the original anchor cannot be established.
  • proposed — Preserve durable deletion intent or a resumable cleanup checkpoint until all owned history is erased, and make subsequent maintenance discover incomplete deletions even after the lead document disappears. Keep new writes blocked during deletion and retain the existing client-denial boundary.

…ion (#152)

Make /admin/trade the system of record for the whole trade relationship:
admins send email from the lead workspace, customer replies and forwarded
mail attach automatically via per-lead inbound routing addresses, and the
unified timeline shows communications alongside notes and lifecycle events.

- Per-lead opaque replyToken (never the Firestore id) forms the inbound
  address <token>@<reply domain>; Reply-To on outbound mail routes
  customer replies back, and staff can forward outside email to attach it
- POST /api/webhooks/resend verifies svix signatures before touching the
  payload, resolves leads by token, dedupes by provider email id, and
  correlates threads via In-Reply-To/References against stored
  Message-IDs
- Delivery callbacks (delivered/bounced/delayed/complained/failed) advance
  communication state monotonically; replays never regress it
- Staff notifications: blanket new-inquiry alert to
  TRADE_NOTIFICATION_EMAIL (legacy TRADE_INQUIRY_TO_EMAIL fallback), and
  customer-reply alerts to the assigned owner's admin email or the shared
  mailbox when unassigned
- Full communication records in tradeLeads/{id}/communications with a
  compact communication summary on the matching activity entry; bodies
  stay out of the timeline, analytics, and logs
- First-class island field (canonical venue-island vocabulary) on leads,
  public form, manual create, list badges, detail header, and filtering
- Conservative phone normalization (E.164 where confidently parsed) with
  readable display and tel:/wa.me links; ambiguous input stays raw
- Retention pruning now sweeps both activities and communications

Review feedback on #154:
- applyDeliveryEvent now runs the rank check and write in a transaction so
  concurrent provider events cannot regress the stored delivery state
- telHref falls back to raw digits for unparseable numbers, preserving a
  call link where the previous UI always offered one
- the ?lead= deep link only follows id-shaped values and openLead encodes
  the id before fetching
- docs corrected: TRADE_FROM_EMAIL falls back to RESEND_FROM_EMAIL, then

- Retry of a failed/stuck outbound send now reuses the recorded
  communication: the doc id is the Resend idempotency key, the stored
  subject/body must match the draft, and a communication that already
  carries a provider id short-circuits — a send accepted before its
  Firestore update failed can no longer mail the customer twice.
- Timeline gains a Resend action on queued/failed outbound entries and
  the composer retries the same send when the draft is unchanged.
- telHref keeps a leading "+" in the raw-digit fallback for numbers
  that never normalize.
- Admin doc no longer claims every trade-lead write flows through
  /api/admin/* — the signed Resend webhook is a separate write path.

🟡 Minor · Return the communication ID when detail loading fails. · route.ts:48-64

app/api/admin/trade-leads/[id]/messages/route.ts:48-64
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Return the communication ID when detail loading fails.

After sendLeadEmail returns, a Firestore read or reply-token transaction in getTradeLeadDetail can fail. The generic error response omits communicationId. On a first send, the workspace therefore keeps the draft but cannot set emailRetry. Resubmitting it omits retryCommunicationId, creates a new communication, and can send a duplicate email. Return the completed send’s ID in this post-send error response so the client retries the existing communication.

- A post-send Firestore failure or transport error now throws a
  send error carrying the communication id, so the route returns it
  and the client retry replays the same send instead of composing a
  duplicate.
- Resend only retains idempotency keys for 24h: each dispatch stamps
  sendAttemptAt, and a queued resend is refused once the prior attempt
  is past the safe window (failed sends stay resendable — the provider
  rejected them, nothing was dispatched).

🟡 Minor · Preserve the first-use timestamp for queued retries. · trade-leads-email.ts:350-354

lib/trade-leads-email.ts:350-354
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Preserve the first-use timestamp for queued retries.

A transport failure leaves the communication queued. Each retry then replaces sendAttemptAt before reusing the same Resend idempotency key. Repeated retries can therefore dispatch that key after its documented 24-hour deduplication window. Resend no longer guarantees deduplication at that point, so the documented no-duplicate retry contract is not preserved.

Keep sendAttemptAt unchanged for queued retries. Set it only when retrying a provider-rejected failed send.

Suggested fix
-  // Mark the retry as in-flight again so the timeline doesn't keep showing
-  // a stale failure while the provider call runs — and stamp the attempt,
-  // which is what the idempotency-window check measures the next retry
-  // against.
+  // Mark the retry as in-flight again. A queued retry must retain its
+  // original attempt timestamp; a failed send starts a new attempt window.
   tx.update(commRef, {
     deliveryState: "queued",
     deliveryStateAt: FieldValue.serverTimestamp(),
-    sendAttemptAt: FieldValue.serverTimestamp(),
+    ...(state === "failed"
+      ? { sendAttemptAt: FieldValue.serverTimestamp() }
+      : {}),
   });
