# Changelog

User-visible changes in `wacrm`. Self-hosters: when pulling an update,
check this file for any **migration required** notes and apply the
matching SQL files from `supabase/migrations/` against your Supabase
project before restarting the app.

Versions follow [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
Pre-1.0, `MINOR` bumps cover new modules; `PATCH` bumps cover bug fixes
and polish.

## [0.2.2] — 2026-05-29

Flow nodes can now send media. Closes the most-requested gap from user
feedback after the v0.2.0 Flows launch — flows were text-only and
couldn't deliver an invoice, receipt, product photo, or short demo
video mid-conversation.

### Added

- **`send_media` flow node.** Send an image (PNG / JPEG / WebP), video
  (MP4 / 3GP), or document (PDF, Word, Excel, PowerPoint, TXT) to the
  customer from any point in a flow. Pick a file in the builder, it
  uploads to the new `flow-media` Supabase Storage bucket, and Meta
  fetches the public URL at send time. Optional caption (1024 char cap,
  supports `{{vars.X}}` interpolation); documents also take an optional
  filename shown in the recipient's chat. Auto-advances after send —
  same suspend semantics as `send_message`.
  ([#156](https://github.com/ArnasDon/wacrm/pull/156))

### Migration required

Apply against your Supabase project before deploying this version:

- `supabase/migrations/016_flow_media.sql` — does two things:
  1. Adds `'send_media'` to the `flow_nodes.node_type` CHECK
     constraint. Without this the `send_media` node fails to save with
     a constraint violation.
  2. Creates the public `flow-media` Supabase Storage bucket (16 MB
     file-size cap, image / video / document MIME allowlist) plus
     per-user RLS policies (path prefix = `auth.uid()`). Without this
     the builder's file picker fails on upload. Same shape as the
     `avatars` bucket from migration 008 — the bucket is **public** so
     Meta can fetch the URL without credentials.

The migration is idempotent and safe to re-run.

## [0.2.1] — 2026-05-26

Bug-fix release. Plugs a silent inbound-message drop that triggered
when two users on the same instance saved the same WhatsApp
`phone_number_id`.

### Fixed

- **Inbound WhatsApp messages no longer silently disappear** when two
  users have claimed the same `phone_number_id`. Previously the
  webhook used `.single()` to look up the owning config, which errors
  `PGRST116` for both 0 rows *and* ≥2 rows — the second user's save
  put the DB into the ≥2-row state and every inbound message was
  dropped while the log misleadingly reported *"No config found for
  phone_number_id"*. Three layers of fix: `POST /api/whatsapp/config`
  now returns **409** when another user has already claimed the
  number, the webhook lookup distinguishes 0 rows from ≥2 rows and
  logs the conflicting `user_id`s, and a new DB constraint
  (`UNIQUE(phone_number_id)`) prevents the bad state at the storage
  layer. Reported in
  [#136](https://github.com/ArnasDon/wacrm/issues/136), fixed in
  [#143](https://github.com/ArnasDon/wacrm/pull/143).

### Migration required

Apply against your Supabase project before deploying this version:

- `supabase/migrations/013_whatsapp_config_phone_number_id_unique.sql`
  — adds `UNIQUE(phone_number_id)` to `whatsapp_config`. **Fails
  loudly with a copy-pasteable resolution hint** if duplicate rows
  already exist; auto-deduping would destroy encrypted tokens, so
  the operator picks which row keeps the number. To check first:

  ```sql
  SELECT phone_number_id, array_agg(user_id) AS owners, count(*) AS n
  FROM whatsapp_config
  GROUP BY phone_number_id
  HAVING count(*) > 1;
  ```

  If that returns rows, `DELETE` the duplicate row(s) you want to
  drop, then re-run the migration.

### Note on multi-user setups

wacrm is intentionally **single-tenant per WhatsApp number**. RLS on
`conversations`/`messages` is `auth.uid() = user_id`, so a second
user physically cannot read messages routed to a different owner —
two users sharing one number was never supported. If you need
multiple humans handling the same inbox, run them under one shared
account.

## [0.2.0] — 2026-05-22

The **Flows** release. Adds a no-code, branching, button-driven WhatsApp
conversation engine that runs alongside Automations. Also ships a
5-theme color picker in Settings and opens Flows to all users.

### Added

#### Flows — branching chatbot conversations

- **Module + schema.** New `flows`, `flow_nodes`, `flow_runs`,
  `flow_run_events` tables with partial unique indexes that enforce
  one active run per contact. Widened `messages.content_type` CHECK
  to accept `'interactive'`; added `interactive_reply_id` column so
  the inbox can render button/list taps.
  ([#112](https://github.com/ArnasDon/wacrm/pull/112))
- **Runner engine.** `dispatchInboundToFlows` parses every inbound
  webhook, decides whether the message is a reply on an active run
  or a fresh trigger, advances the state machine, and reports back
  to the webhook so consumed messages don't also fire automations.
  Idempotent on Meta's `message_id`.
  ([#114](https://github.com/ArnasDon/wacrm/pull/114))
- **No-code builder UI** at `/flows`. Linear-list editor with
  per-node config forms, live validator, draft/active/archived
  status, and a 5-route REST API (`GET/POST /api/flows`,
  `GET/PUT/DELETE /api/flows/[id]`, `POST /api/flows/[id]/activate`,
  `GET /api/flows/[id]/runs`, `GET /api/flows/templates`).
  ([#115](https://github.com/ArnasDon/wacrm/pull/115))
- **Templates + v1.5 node types.** Three starter templates
  (Welcome menu, FAQ bot, Lead capture) cloneable from the New-flow
  dialog. Three new node types: `collect_input` (capture customer
  text into a variable), `condition` (branch on var / tag / contact
  field), `set_tag` (add or remove a tag). `{{vars.X}}` interpolation
  in send_message + collect_input prompts. Per-flow run-history
  viewer at `/flows/[id]/runs`.
  ([#117](https://github.com/ArnasDon/wacrm/pull/117))
- **Stale-run sweep cron** at `GET /api/flows/cron` — marks runs
  past their configured timeout (default 24h) as `timed_out` so
  abandoned conversations free up the contact for new triggers.
  Reuses `AUTOMATION_CRON_SECRET`.
  ([#114](https://github.com/ArnasDon/wacrm/pull/114))

#### Color themes

- **5 color themes** (Violet default, Emerald, Cobalt, Amber, Rose)
  selectable from a new **Appearance** tab in Settings. CSS variables
  scoped under `html[data-theme="..."]`, applied at runtime via
  `dataset.theme`, persisted to `localStorage`. Inline boot script in
  `layout.tsx` replays the choice before first paint so there's no
  flash of the default.
  ([#132](https://github.com/ArnasDon/wacrm/pull/132))
- **Theme tokenization sweep** — every previously hard-coded
  `violet-*` Tailwind class replaced with `primary` tokens across
  ~49 files. Picking a non-violet theme now themes the whole app,
  not just the chrome.
  ([#133](https://github.com/ArnasDon/wacrm/pull/133))

### Changed

#### Flows — soft-GA

- **Flows is now available to every authenticated user.** The
  per-account beta gate is gone; the sidebar entry + page header
  carry a small "Beta" chip as the only remaining signal.
  ([#134](https://github.com/ArnasDon/wacrm/pull/134))
- **Editor UX**:
  - Internal `node_key` + per-button/row `reply_id` identifiers
    hidden behind a per-node "Show advanced" disclosure.
    ([#118](https://github.com/ArnasDon/wacrm/pull/118))
  - `send_list` nodes can have multiple sections.
    ([#119](https://github.com/ArnasDon/wacrm/pull/119))
  - Collapsed node cards show a 1-line content preview per node
    type (text excerpt, button titles, condition summary, etc.).
    ([#120](https://github.com/ArnasDon/wacrm/pull/120))
  - Validation issues are clickable: jump to + flash the offending
    node.
    ([#121](https://github.com/ArnasDon/wacrm/pull/121))
  - Unsaved-changes "● Edited" indicator + `beforeunload` reload
    guard.
    ([#122](https://github.com/ArnasDon/wacrm/pull/122))
  - New-flow dialog actually widens to fit the 3 template cards
    (was capped at 384px by a baked-in `sm:max-w-sm` from shadcn).
    ([#129](https://github.com/ArnasDon/wacrm/pull/129),
    [#131](https://github.com/ArnasDon/wacrm/pull/131))
  - Validation panel pinned to the viewport bottom so
    activate-readiness follows the user as they scroll through nodes.
    ([#130](https://github.com/ArnasDon/wacrm/pull/130))

#### Engine reliability

- **Atomic `execution_count` increment** via SECURITY DEFINER RPC —
  prevents lost counts when two webhooks start runs concurrently.
  Mirrors the automations engine pattern.
  ([#124](https://github.com/ArnasDon/wacrm/pull/124))
- **Preload all flow_nodes once per dispatch** — one SELECT per
  inbound instead of one per advance-loop iteration. A 5-node
  auto-advance chain now costs 1 round trip, not 5.
  ([#125](https://github.com/ArnasDon/wacrm/pull/125))
- **Wasted re-read dropped** after reprompt reset; `loadActiveRun`
  switched to defensive `.limit(1)` so a migration glitch producing
  duplicates can't crash dispatch.
  ([#126](https://github.com/ArnasDon/wacrm/pull/126))

### Security

- **PII redacted from `reply_received` event payload** — customer
  text is no longer persisted to `flow_run_events.payload`; only
  the length is. A `collect_input` prompt asking "what's your card
  number?" used to leave the PAN sitting in the events table.
  ([#123](https://github.com/ArnasDon/wacrm/pull/123))
- **Constant-time cron-secret compare** on `/api/flows/cron`
  (`crypto.timingSafeEqual`) to close a theoretical
  timing-side-channel on the `x-cron-secret` header check.
  ([#127](https://github.com/ArnasDon/wacrm/pull/127))

### Fixed

- **`/flows` no longer spuriously redirects to `/dashboard`** when
  navigating in. Root cause: `useAuth` flipped `loading: false`
  before the profile fetch resolved. `use-auth` now exposes a
  separate `profileLoading` boolean.
  ([#128](https://github.com/ArnasDon/wacrm/pull/128))

### Migration required

Apply, in order, against your Supabase project:

1. `supabase/migrations/010_flows.sql` — Flows core tables, indexes,
   RLS policies, and the `messages` schema widening.
2. `supabase/migrations/011_profile_beta_features.sql` — adds the
   `profiles.beta_features` column. Surviving for future betas;
   Flows no longer reads it.
3. `supabase/migrations/012_flows_increment_counter.sql` — atomic
   counter RPC. Without this the engine still runs but
   `flows.execution_count` is racy.

Each migration is idempotent — safe to re-run if you're not sure
whether you applied a previous one.

### Removed

- **`src/lib/flows/feature-flag.ts`** + its tests. Flows is open to
  all users; the `profiles.beta_features` column itself survives
  for future beta gates.
  ([#134](https://github.com/ArnasDon/wacrm/pull/134))

## [0.1.1] — 2026-05-19

### Added

- Chat actions in the inbox: emoji reactions, reply-with-quote, and
  copy-text on individual messages. Hover on desktop, long-press on
  touch. Outbound reactions and replies forward to WhatsApp via the
  Cloud API; inbound reactions and swipe-replies from customers
  arrive through the webhook and appear in real time.

### Migration required

- Apply `supabase/migrations/009_message_actions.sql` to your
  Supabase project. It adds `messages.reply_to_message_id` and the
  new `message_reactions` table (with RLS and realtime). The
  migration is idempotent — safe to re-run.

### Changed

- The webhook no longer stores inbound customer reactions as fake
  text messages. They are written to `message_reactions` instead,
  so any custom queries that counted reactions as messages will
  need updating.
