send_message and send_template steps were inserting a row into
messages with status='sending' but never calling Meta's WhatsApp API,
so automation replies appeared in the inbox but never reached the
phone. send_template was a plain noop ("template send recorded").
- New helper src/lib/automations/meta-send.ts mirrors the logic in
/api/whatsapp/send (decrypt config, phone-variant retry, persist
messages row with status='sent' and the real whatsapp message id).
Kept as a separate helper to avoid touching the working manual-send
route; the two can converge in a later refactor.
- Engine's send_message / send_template now await the helper and
surface Meta errors through the existing per-step failure path,
so a bad token / invalid template shows up in automation_logs with
status='failed' instead of silently "sending" forever.
- Consolidated automation dispatches in the webhook to fire after the
conversation is created. Previously new_contact_created raced the
conversation insert, which could have made send_message fail to
resolve a target conversation.

Replaces the /automations placeholder with a full feature:
- Migration 006 adds automations, automation_steps, automation_logs,
and automation_pending_executions with RLS matching existing tables.
- List page with active/inactive switch, quick-start templates,
duplicate, delete, and View Logs actions.
- Full-screen vertical flow builder with Trigger + Action + Condition
(Yes/No branches) + Wait cards. Inline edit forms, up/down reorder,
dotted-grid canvas.
- Execution engine (src/lib/automations/engine.ts) dispatched from the
WhatsApp webhook for new_message_received, new_contact_created, and
keyword_match. Wait steps enqueue to automation_pending_executions;
/api/automations/cron drains them behind AUTOMATION_CRON_SECRET.
- Logs viewer with per-step checkmarks and expandable detail.
Existing files touched only in webhook/route.ts (fire-and-forget
trigger dispatch) and types/index.ts (appended automation types).

Fixes 8 real issues found during a thorough review of the broadcast
feature (PRs #21-#29).
Security
* Webhook POSTs had zero spoof protection. Anyone could forge a
status update and drift broadcast counts arbitrarily. Added
HMAC-SHA256 signature verification via the X-Hub-Signature-256
header (Meta's standard). New helper src/lib/whatsapp/webhook-
signature.ts with timing-safe comparison. Rollout fails open
with a warning when META_APP_SECRET is unset so existing
deploys don't break at rollout; set the env var to enforce.
Correctness
* CSV audience was completely broken — synthesized "csv-N" strings
as contact_id, which failed the UUID cast on insert. Every CSV
broadcast silently created zero recipients. Replaced with a
real find-or-create against the contacts table (batched lookup
by phone, single INSERT for missing rows, de-duplicates CSV
inputs). CSV contacts now end up as real contacts.rows with
real UUIDs flowing through the rest of the pipeline.
* Recipient insert errors were logged with console.error and the
loop marched on — broadcasts then ran with incomplete recipient
sets, webhook updates couldn't find rows, and aggregate counts
drifted. Now: on batch insert failure, flip the broadcast to
failed + failed_count=total + throw so handleSend's toast fires.
* Webhook status guard ordered "failed" above "replied", which
meant a webhook replay delivering "failed" for an already-
replied recipient would upgrade replied → failed. Split the
ladder: forward-only ordering across pending → sent →
delivered → read → replied; failed is a terminal side branch
that can only be reached from pending or sent (never from any
success state). Net effect: a message that was read can no
longer regress to failed on a replay.
* Template sync only pulled page 1 (ignored paging.next). Users
with >100 templates silently missed some, and broadcasts with
those names failed with Meta's "template not found". Now
follows paging.next with a 20-page safety cap, reports
truncated=true in the response if hit.
* Template sync reported success:true even when individual
upserts failed. Now accumulates per-template errors and
surfaces them via a separate toast.error in the UI — green
toast no longer hides silent drift.
Performance
* Migration 005: replace the broadcast_recipients aggregate
trigger installed in migration 003. Old version ran
COUNT(*) FILTER on every row change — O(n²) across a send
loop (10k recipients × 10k index scans). New version
increments / decrements by ±1 per status transition: O(1)
per change. Kept the old recompute_broadcast_counts() as a
callable safety-net in case of drift.
* List page poll kept running while the tab was hidden. Added
visibilitychange handler — polling pauses when hidden,
resumes (and does an immediate fetch) on refocus.
UX
* Step 3 (Personalize) let users skip past unmapped placeholders
→ broadcasts then sent to Meta with empty-string params.
Next is now disabled until every {{N}} has a value; an amber
warning lists the missing placeholders.
Documented accepted risks in the PR body.

Three correctness bugs were making the existing broadcast flow wrong,
not just incomplete.
1. Per-recipient variables were broken
use-broadcast-sending.ts computed templateParams per contact but shipped
only templateParams[0] to the API, so every contact in a batch received
contact 0's personalization (name/email/etc).
Fix: extend POST /api/whatsapp/broadcast to accept a per-recipient
shape `{ recipients: [{ phone, params }], ... }`. Legacy
`{ phone_numbers, template_params }` still accepted. Hook sends per-
recipient payloads; API returns whatsapp_message_id per phone.
2. Webhook never updated broadcast_recipients
handleStatusUpdate in webhook/route.ts only mirrored Meta status onto
the `messages` table. broadcast_recipients had no correlation column,
so delivered_count / read_count / replied_count never advanced for
real broadcasts.
Fix (migration 003):
- broadcast_recipients.whatsapp_message_id (+ UNIQUE index) for
Meta-message-id correlation
- composite index (broadcast_id, status) for fast aggregate scans
- AFTER INSERT/UPDATE/DELETE trigger that recomputes parent
broadcasts counts via COUNT(*) FILTER — sender + webhook only
touch the recipient row, aggregates stay consistent
Webhook:
- handleStatusUpdate also updates broadcast_recipients with forward-
only status guard (read cannot regress to sent on a replay)
- processMessage flags the replied recipient row when an inbound
message arrives from a recent broadcast contact
3. Rate limiting did not match spec
Batch 50 / no delay → Batch 10 / 1s between batches, matching the spec
and Meta's per-phone-number rate ceiling.
Also: extract statusConfig from both page components into
src/lib/broadcast-status.ts (single source of truth for PR B). Add
whatsapp_message_id to BroadcastRecipient type.

Over the course of the project the same swapped-args bug was found
four separate times against the Meta API helpers (config in PR #8,
send in PR #12, broadcast in PR #13, webhook media in PR #14). Each
time the compiler accepted the call because all the args were
strings, so the bug only surfaced at runtime as an opaque Meta error.
This refactor eliminates the entire bug class by converting every
helper to a single options object. A typo like
sendTextMessage({ accessToken: id, phoneNumberId: tok, ... })
is now a TypeScript error at the call site rather than a 400 from
Meta two layers deep.
Helpers updated in src/lib/whatsapp/meta-api.ts:
- verifyPhoneNumber({ phoneNumberId, accessToken })
- sendTextMessage({ phoneNumberId, accessToken, to, text })
- sendTemplateMessage({ phoneNumberId, accessToken, to, templateName, language?, params? })
- getMediaUrl({ mediaId, accessToken })
- downloadMedia({ downloadUrl, accessToken })
Each exported Args interface so routes can type local variables
holding partial argument sets (useful for the broadcast retry loop).
Also factored the duplicated "parse Meta error JSON" block into a
shared throwMetaError() helper — was repeated in 5 places.
Call sites updated (all were already correct after prior fixes, but
now the types enforce it):
- src/app/api/whatsapp/config/route.ts (GET + POST)
- src/app/api/whatsapp/send/route.ts (attempt() closure)
- src/app/api/whatsapp/broadcast/route.ts (retry loop)
- src/app/api/whatsapp/webhook/route.ts (verifyAndBuildUrl)
- src/app/api/whatsapp/media/[mediaId]/route.ts (proxy pipeline)
No behavior change. Build passes.

Meta WhatsApp returns error #131030 ("Recipient phone number not in
allowed list") in two situations:
1. Sandbox: the recipient isn't registered as a test number.
2. The registered number format differs from what we sent, usually
because of trunk-prefix 0 quirks (e.g. Lithuanian numbers stored
as +370063949836 vs international +37063949836).
Today that error bubbles up to the UI and the user has to manually
edit the contact. This PR makes the send pipeline self-heal: on 131030
it retries with alternate phone-number formats, and if an alternate
works it persists the corrected format back to the contact so future
sends are a single API call.
src/lib/whatsapp/phone-utils.ts
- Added phoneVariants(sanitized) — yields original, then variants with
a trunk 0 inserted/removed after each plausible country-code length
(1-3 digits). Deduplicated. Original is always first so the fast
path for correctly-formatted numbers is one attempt.
- Added isRecipientNotAllowedError(message) helper — matches
code 131030 or the English error text, so we only retry when the
failure is actually about the recipient (other errors fail fast).
src/app/api/whatsapp/send/route.ts
- Reply send now iterates phoneVariants() and stops at the first that
succeeds. If a non-original variant works, contacts.phone is updated
to the working format.
src/app/api/whatsapp/broadcast/route.ts
- Same retry applied per recipient in the broadcast loop.
- Also fixed a separate bug: broadcast was calling
sendTemplateMessage(accessToken, phone_number_id, ...) — wrong order.
Correct signature is (phoneNumberId, accessToken, to, templateName,
language?, params?). This was silently rejecting every broadcast.

Fixes two runtime errors:
1. "Lock 'lock:sb-xxx-auth-token' was released because another request
stole it" — caused by multiple Supabase client instances competing
for the same auth storage lock.
2. "Failed to fetch conversations: {}" — related to #1. When the auth
lock is stolen mid-request, the session becomes temporarily
unavailable and queries fail.
The codebase had 65 call sites invoking createClient() — each creating
a new browser client with its own auth listener. This change makes
createClient() cache and return a single shared instance.
Also improved error logging in conversation-list.tsx to show Supabase
error fields (message/details/hint/code) instead of an empty {}.
