## Description
Add account setting and store_accessor for
`captain_force_legacy_auto_resolve`.
Enterprise job now skips LLM evaluation when this flag is true and falls
back to legacy time-based resolution. Add spec to cover the fallback.
## Type of change
We recently rolled out Captain deciding if a conversation is resolved or
not. While it is an improvement for majority of customers, some still
prefer the old way of auto-resolving based on inactivity. This PR adds a
check.
## How Has This Been Tested?
Please describe the tests that you ran to verify your changes. Provide
instructions so we can reproduce. Please also list any relevant details

## Description
CJK language users (Chinese, Japanese, Korean, etc.) use IME where Enter
confirms character selection. AI input components were intercepting
Enter unconditionally, making them unusable for IME users.
Add `event.isComposing` check to CopilotEditor, CopilotInput, and
AssistantPlayground so Enter during active IME composition is ignored.

Before:
Add a Japenese keyboard, then go to AI follow-ups, type some word,
selecting it with enter submits the follow up. So CJK users cannot use
follow-ups.

When the SDK sends identify calls with identical payloads (common on
every page load), `save!` fires even though no attributes changed. While
Rails skips the actual UPDATE SQL, it still opens a transaction, runs
all callbacks (including validation queries like `Contact Exists?`), and
triggers `after_commit` hooks — all for a no-op.
This adds a `changed?` guard before `save!` to skip it entirely when no
attributes have actually changed.
**How to test**
- Trigger an identify call via the SDK with a contact's existing
attributes (same name, email, custom_attributes, etc.)
- The contact should not fire a save (no transaction, no callbacks)
- Trigger an identify call with a changed attribute — save should work
normally
**What changed**
- `ContactIdentifyAction#update_contact`: guard `save!` with `changed?`
check
- Added specs to verify `save!` is skipped for unchanged params and
avatar job still enqueues independently
Removes touch: true from the belongs_to :conversation association on
Message and consolidates the conversation timestamp update into the
existing set_conversation_activity callback.
Previously, every message save triggered two separate UPDATE queries on
the conversation — one from Rails' touch (updating updated_at) and
another from set_conversation_activity (updating last_activity_at). This
combines both into a single update_columns call, reducing write load on
the conversations table on every message creation.
### What changed
- Removed touch: true from belongs_to :conversation in Message
- Added updated_at: created_at to the existing update_columns call in
set_conversation_activity
# Pull Request Template
## Description
Unconfirmed agents (pending email verification) were incorrectly
appearing in the "assign agent" dropdown for macros and automations.
This fix filters out unconfirmed agents from these dropdowns and adds
backend validation to prevent assignment of unconfirmed agents.
Fixes#13223
## Type of change
- [x] Bug fix (non-breaking change which fixes an issue)
## How Has This Been Tested?
**Backend tests:**
```bash
docker compose run --rm rails bundle exec rspec spec/services/action_service_spec.rb
```
- Added tests for confirmed agent assignment (should succeed)
- Added tests for unconfirmed agent assignment (should be skipped)
**Frontend tests:**
```bash
docker compose run --rm rails pnpm test app/javascript/dashboard/composables/spec/useMacros.spec.js
```
- Updated mocks to use `getVerifiedAgents` getter
**Manual testing:**
1. Create an unconfirmed agent via platform
2. Navigate to Settings → Macros → New Macro → Add "Assign Agent" action
3. Verify unconfirmed agent does NOT appear in dropdown
4. Navigate to Settings → Automations → New Automation → Add "Assign
Agent" action
5. Verify unconfirmed agent does NOT appear in dropdown

## Description
This PR optimizes message queries by explicitly filtering with
`account_id` so the database can use the existing indexes more
efficiently.
Changes:
- Add `account_id` to message query filters to improve index
utilization.
- Update `last_incoming_message` query to include `account_id`.
- Avoid unnecessary preloading of `contact_inboxes` where it is not
required.
- Update specs to ensure `account_id` is set correctly in
message-related tests.
These changes reduce query cost and improve performance for message
lookups, especially on large accounts.

This makes account signup enforcement consistent when signup is disabled
at the installation level. Email signup and Google signup now stay
blocked regardless of whether the config value is stored as a string or
a boolean.
This effectively covers the config-loader path, where `YAML.safe_load`
reads `value: false` from `installation_config.yml` as a native boolean
and persists it that way.
- Normalized the account signup check so disabled signup is handled
consistently across config value types.
- Reused the same check across API signup and Google signup entry
points.
- Added regression coverage for the disabled-signup cases in the
existing controller specs.

- Extracted 6 custom attribute methods (`custom_attribute_query`,
`attribute_model`, `attribute_data_type`, `build_custom_attr_query`,
`custom_attribute`, `not_in_custom_attr_query`) into a new
`Filters::CustomAttributeFilterHelper` module.
- Added an inline `rubocop:disable` for the intentional
`Lint/ShadowedException` in `coerce_lt_gt_value` — `Date::Error` is a
subclass of `ArgumentError`, but both are listed explicitly for clarity.
## Why `app/services/filters/`
The existing `Filters::FilterHelper` lives in `app/helpers/filters/`,
but that location triggers `Rails/HelperInstanceVariable` for any module
that uses instance variables. The extracted methods share state with
`FilterService` via instance variables (`@attribute_key`, `@account`,
`@custom_attribute`, etc.), so placing them in `app/helpers/` would
require a cop disable.
`app/services/filters/` is a better fit because:
- The module is a service mixin, not a view helper — it's only included
by `FilterService` and its subclasses (`Conversations::FilterService`,
`Contacts::FilterService`, `AutomationRules::ConditionsFilterService`).
- It sits alongside the services that use it.
- No cop disables needed.

On self-hosted instances without email configured, users created from
Super Admin can get stuck in an unconfirmed state. This PR implements
the default at the Super Admin frontend form layer, not in backend
creation logic.
What changed:
- Added a custom `ConfirmedAtField` for Super Admin user forms.
- Prefills `confirmed_at` with current time on the **New User** form
(`GET /super_admin/users/new`).
- Kept backend create behavior unchanged
(`resource_class.new(resource_params)`), so API/manual payloads still
behave normally.
Behavior:
- In Super Admin UI, `confirmed_at` is prefilled by default.
- If someone wants an unconfirmed user, they can clear the
`confirmed_at` field before saving.
- If `confirmed_at` is omitted from payload entirely, the created user
remains unconfirmed.
Scope note: external signup flows are intentionally unchanged in this PR
(`/api/v1/accounts`, `/api/v2/accounts`, and social/omniauth signup
behavior are not modified).

Reduces the frequency of update_presence WebSocket calls from the live

Agents using API channel inboxes (e.g., WhatsApp Automate) reported
seeing the same conversation appear twice in their conversation list —
one showing the last message preview and the other showing "No
Messages". Backend investigation confirmed no duplicate conversations
exist in the database, making this purely a frontend issue.
The root cause is a race condition in WebSocket event delivery. When a
conversation is created via the API with auto-assignment, the backend
enqueues multiple ActionCable broadcast jobs (`conversation.created`,
`assignee.changed`, `team.changed`) within milliseconds of each other.
In production with multi-threaded Sidekiq workers, these events can
arrive at the frontend out of order. If `assignee.changed` arrives
before `conversation.created`, the `UPDATE_CONVERSATION` mutation pushes
the conversation into the store (since it doesn't exist yet), and then
`ADD_CONVERSATION` blindly pushes it again — resulting in a duplicate
entry.
The fix adds a uniqueness check in the `ADD_CONVERSATION` mutation to
skip the push if a conversation with the same ID already exists in the
store, matching the dedup pattern already used by
`SET_ALL_CONVERSATION`.
## Summary
This Enterprise-only feature automatically fetches a favicon for
companies created with a domain, and adds a batch task to backfill
missing avatars for existing companies. The flow only targets companies
that do not already have an attached avatar, so existing avatars are
left untouched.
## Demo
https://github.com/user-attachments/assets/d050334e-769f-4e46-b6e7-f7423727a192
## What changed
- Added `Avatar::AvatarFromFaviconJob` to build a Google favicon URL
from the company domain and fetch it through `Avatar::AvatarFromUrlJob`
- Triggered favicon fetching from `Company` with `after_create_commit`
- Added `Companies::FetchAvatarsJob` to batch existing companies that
are missing avatars
- Added `companies:fetch_missing_avatars` under `enterprise/lib/tasks`
- Kept the company-specific implementation inside the Enterprise
boundary
- Stubbed the new favicon request in unrelated specs that now hit this
callback indirectly
- Updated a couple of CI-sensitive specs that were failing due to
callback side effects / reload-safe exception assertions
## How to verify
1. Create a company in Enterprise with a valid domain and no avatar.
2. Confirm that a favicon-based avatar gets attached shortly after
creation.
3. Create another company with a domain and an avatar already attached.
4. Confirm that the existing avatar is not replaced.
5. Run `companies:fetch_missing_avatars`.
6. Confirm that existing companies without avatars get one, while
companies that already have avatars remain unchanged.
## Notes
- This change does not refresh or overwrite existing company avatars
- Favicon fetching only runs for companies with a present domain
- The branch includes the latest `develop`

Agent bot conversations now feel more natural because AgentBot tokens
can toggle typing status, so end users see a live typing indicator in
the widget while the bot is preparing a reply. This keeps the
interaction responsive and human-like without weakening token
authorization boundaries.
## Closes
- https://github.com/chatwoot/chatwoot/issues/8928
- https://linear.app/chatwoot/issue/CW-5205
## How to test
1. Open the widget and start a conversation as a customer.
2. Connect an AgentBot to the same inbox.
3. Trigger `toggle_typing_status` with the AgentBot token
(`typing_status: on`).
4. Confirm the customer sees the typing indicator in the widget.
5. Trigger `toggle_typing_status` with `typing_status: off` and confirm
the indicator disappears.
## What changed
- Added `toggle_typing_status` to bot-accessible conversation endpoints.
- Restricted bot-accessible endpoint usage to `AgentBot` token owners
only (non-user tokens like `PlatformApp` remain unauthorized).
- Updated typing status flow to preserve AgentBot identity in
dispatch/broadcast paths.
- Added request coverage for AgentBot success and PlatformApp
unauthorized behavior.
- Added Swagger documentation for `POST
/api/v1/accounts/{account_id}/conversations/{conversation_id}/toggle_typing_status`
and regenerated swagger artifacts.

Instagram external echo messages were being saved with status:
delivered, but the message meta UI did not treat Instagram as a channel
eligible for delivered-state rendering. As a result, these messages fell
back to progress and showed as “Sending”. This change updates the
message status mapping in the new message UI to include Instagram in the
delivered-state condition.
This PR updates Facebook Messenger outbound tagging in Chatwoot to
support Human Agent messaging when enabled.
Previously, Facebook outbound text and attachment messages were always
sent with:
```
messaging_type: MESSAGE_TAG
tag: ACCOUNT_UPDATE
```
With this change, the tag is selected dynamically:
```
HUMAN_AGENT when ENABLE_MESSENGER_CHANNEL_HUMAN_AGENT is enabled
ACCOUNT_UPDATE as fallback when the flag is disabled
```
This fixes the agent-bot webhook delivery path so transient upstream
failures follow the expected delivery lifecycle. Existing fallback
behavior is preserved, and fallback actions are applied only after
delivery attempts are exhausted.
To reproduce, configure an agent-bot webhook endpoint to return 429/500
for message events. Before this fix, failure handling could be applied
too early; after this fix, delivery attempts complete first and then
existing fallback handling runs.
Tested with:
- bundle exec rspec spec/jobs/agent_bots/webhook_job_spec.rb
spec/lib/webhooks/trigger_spec.rb
- bundle exec rubocop spec/jobs/agent_bots/webhook_job_spec.rb
spec/lib/webhooks/trigger_spec.rb

When agents send replies from the native Facebook Messenger app (not
Chatwoot), echo events were created without external_echo metadata and
could be misrepresented in the UI. This change updates Messenger echo
message creation to:
- set content_attributes.external_echo = true for outgoing_echo messages
- set echo message status to delivered
- keep sender as nil for echo messages (existing behavior)

## Description
PLAIN IMAP channels (non-OAuth) were silently retrying failed
authentication every minute, forever. When credentials are
wrong/expired, Net::IMAP::NoResponseError was caught and logged but
channel.authorization_error! was never called — so the Redis error
counter never incremented, reauthorization_required? was never set, and
admins were never notified. OAuth channels already had this handled
correctly via the Reauthorizable concern.
Additionally, Net::IMAP::ResponseParseError (raised by non-RFC-compliant
IMAP servers) was falling through to the StandardError catch-all,
flooding
Estimated impact before fix: ~70–75 broken IMAP inboxes generating
~700k–750k wasted Sidekiq jobs/week.

## Summary
This PR enables and surfaces **conversation workflow** for social-style
channels that should support either:
- `Create new conversations` after resolve, or
- `Reopen same conversation`
## What is included
- Adds the conversation workflow setting UI as card-based options in
Inbox Settings.
- Expands channel availability in settings to include channels like:
- Telegram
- TikTok
- Instagram
- Line
- WhatsApp
- Facebook
- Updates conversation selection behavior for Line incoming messages to
respect the workflow (reopen vs create-new-after-resolved).
- Updates TikTok conversation selection behavior to respect the workflow
(reopen vs create-new-after-resolved).
- Keeps email behavior unchanged (always starts a new thread).
Fixes: https://github.com/chatwoot/chatwoot/issues/8426

### Changes
- Replace `vue-virtual-scroller`
(`DynamicScroller`/`DynamicScrollerItem`) with `virtua`'s `Virtualizer`
component
- Remove `IntersectionObserver`-based infinite scroll in favor of
`Virtualizer`'s `@scroll` event with offset-based bottom detection
- Remove `useEventListener` scroll binding and
`intersectionObserverOptions` computed
- Simplify item rendering — no more `DynamicScrollerItem` wrapper or
`size-dependencies` tracking; `virtua` measures items automatically
