Round-robin queue resets now leave the Redis queue empty when an inbox
has no members, avoiding an invalid sorted-set write while keeping
normal queue population unchanged.

- [Sentry 7663380084](https://chatwoot-p3.sentry.io/issues/7663380084/)
## How to reproduce
Run round-robin assignment for an inbox with no inbox members. Resetting
the queue previously attempted a Redis sorted-set write without any
member/score pairs.
## What changed
- Clear the existing queue as before.
- Skip queue population when there are no eligible user IDs.
- Add service coverage for an inbox with no members.
AgentBot-owned conversations are now treated as assigned across
conversation lists, counts, pagination, permissions, unread membership,
human auto-assignment, and advanced assignee filters.

## Follow-ups
-
https://linear.app/chatwoot/issue/CW-7870/refresh-agentbot-ownership-state-when-deleting-an-agent-bot
tracks ownership refresh during AgentBot deletion.
-
https://linear.app/chatwoot/issue/CW-7899/refresh-saved-filter-totals-after-live-conversation-ownership-changes
tracks the existing saved-filter header count refresh gap.
## Why
The backend treated every conversation without a human assignee as
unassigned, even when an AgentBot owned it. The frontend already hid
AgentBot-owned conversations from the Unassigned list, so counts,
pagination, filters, unread membership, direct-access permissions, and
auto-assignment could disagree with the visible queue.
## What changed
- Treat conversations with either a human assignee or AgentBot owner as
assigned.
- Keep conversation counts, pagination, unread memberships, advanced
filters, and automation assignee conditions aligned with the shared
ownership semantics.
- Keep human assignee equality and not-equality filters human-only, even
when a human and AgentBot have the same numeric ID.
- Exclude AgentBot-owned conversations from both legacy and V2 human
auto-assignment, and from unassigned-only Enterprise access.
- Preserve AgentBot ownership when Twilio or WhatsApp call flows reuse
or accept an assigned conversation.
- Emit ownership-change updates when only the AgentBot owner changes, so
connected clients refresh queue state.
## Validation
- AgentBot assignment changed ownership to the bot, moved the
conversation to pending, and removed it from the open queue.
- Assignee "is present" returned human- and AgentBot-owned
conversations; "is not present" returned only genuinely unassigned
conversations.
- Automation assignee presence conditions treated AgentBot ownership as
present and did not execute the absent-owner path.
- Live human-assignee equality and not-equality filters excluded
AgentBot-owned conversations, including numeric ID collisions.
- A 32-conversation pending queue loaded across pagination with matching
totals and no missing or duplicate rows.
- AgentBot ownership changes and human takeover updated filtered rows
immediately without a reload.
- Human takeover opened the conversation and restored the public reply
composer; subsequent unassignment kept the conversation open.
- An unassigned-only custom-role agent saw only genuinely unassigned
conversations and could not see AgentBot-owned conversations.
- AgentBot-owned conversations showed the handled-by-bot banner, Take
over action, and disabled public reply composer.
- New conversations in the connected inbox were assigned to the AgentBot
and excluded from human auto-assignment.
- Opening an AgentBot-owned conversation did not let the legacy
assignment callback or its locked recheck replace the bot.
- Moving an AgentBot-owned conversation to an auto-assigning team
preserved the bot and did not create a second human owner.
- Twilio conference pickup, Twilio outbound reuse, WhatsApp outbound
reuse, and inbound WhatsApp acceptance preserved existing AgentBot
owners.
- Focused ownership, filters, pagination, permissions, unread-count,
auto-assignment, frontend, and lint checks passed locally.
- GitHub Actions, Docker builds, CircleCI, security checks, and the
final Codex review are green on the final head.
## Description
Auto-assignment was skipping the 7-day staleness check entirely for
inboxes that don't have an assignment policy attached. Those inboxes
would pull unassigned conversations of any age off the backlog and hand
them to agents — including conversations untouched for months — while
the activity log still credited "Default Policy" for the assignment.
This makes the default behaviour match what that label implies: with no
policy configured, conversations with no activity in the last 7 days are
now excluded, the same window a freshly created policy uses.

## Description
Assignment policies now skip stale unassigned conversations
automatically. Each policy carries an age threshold (defaults to 7
days), so auto-assignment only picks up recent backlog instead of
draining very old, forgotten conversations. The threshold is
configurable per policy and can be cleared to assign conversations
regardless of age. Previously this control existed only on Enterprise
capacity policies (`exclude_older_than_hours`); it now lives on the
assignment policy itself, so every V2 inbox benefits without needing a
capacity policy.

## Description
When an inbox has `enable_auto_assignment` and `assignment_v2` enabled
but no agents are currently online,
`AutoAssignment::AssignmentService#perform_bulk_assignment` still loaded
up to 100 unassigned conversations and iterated each one, calling
`inbox.available_agents` per conversation. Each call hits Redis presence
lookups that return empty, no conversations get assigned, and the loop
finishes having done only wasted work.
For a busy inbox with a long unassigned backlog and offline agents, this
is hundreds of Redis ops per job, multiplied by every
`AutoAssignment::AssignmentJob` enqueue from the per-save handler. The
pressure is significant when inbound volume is high.
This adds a single early-return guard: if
`inbox.available_agents.empty?`, return `0` immediately. Existing
semantics are preserved (jobs are still enqueued on conversation events;
they just exit cheaply when there is no one to assign to).
## Type of change
- [x] Performance improvement (non-breaking change)
## Test coverage
- [x] Added specs
## Description
AutoAssignment::RateLimiter#within_limit? returned true early for
inboxes without an AssignmentPolicy, bypassing fair distribution
entirely and allowing unlimited conversation assignment.

## Description
Fixes a critical bug where conversations assigned to a team could be
auto-assigned to agents outside that team when all team members were at
capacity.

misconfiguration of `allow_auto_assign` or team membership could cause
conversations to remain unassigned.

> Prevents auto-assignment from crossing team boundaries by filtering
eligible agents to the conversation’s `team` members (and requiring
`team.allow_auto_assign`) in both the legacy `AutoAssignmentHandler`
path and the v2 `AutoAssignment::AssignmentService` (including the
Enterprise override).

team members, and are skipped when team auto-assign is disabled or no
team members are available; also updates the conversations controller

> [!NOTE]
> **Medium Risk**
> Changes auto-assignment execution paths, rate limiting defaults, and
feature-flag gating (including premium plan behavior), which could
affect which conversations get assigned and when. UI rewires inbox
settings and policy flows, so regressions are possible around
navigation/linking and feature visibility.
>
> **Overview**
> **Adds a new premium `advanced_assignment` feature flag** and uses it
to gate capacity/balanced assignment features in the UI (sidebar entry,
settings routes, assignment-policy landing cards) and backend
(Enterprise balanced selector + capacity filtering).
`advanced_assignment` is marked premium, included in Business plan
entitlements, and auto-synced in Enterprise accounts when
`assignment_v2` is toggled.
>
> **Improves Assignment V2 policy UX** by adding an inbox-level
“Conversation Assignment” section (behind `assignment_v2`) that can
link/unlink an assignment policy, navigate to create/edit policy flows
with `inboxId` query context, and show an inbox-link prompt after
creating a policy. The policy form now defaults to enabled, disables the
`balanced` option with a premium badge/message when unavailable, and
inbox lists support click-to-navigate.
>
> **Tightens/adjusts auto-assignment behavior**: bulk assignment now
requires `inbox.enable_auto_assignment?`, conversation ordering uses the
attached `assignment_policy` priority, and rate limiting uses
`assignment_policy` config with an infinite default limit while still
tracking assignments. Tests and i18n strings are updated accordingly.

## Linear Link
## Description
This PR introduces a new robust auto-assignment system for conversations
in Chatwoot. The system replaces the existing round-robin assignment
with a more sophisticated service-based architecture that supports
multiple assignment strategies, rate limiting, and Enterprise features
like capacity-based assignment and balanced distribution.
## Type of change
- [ ] New feature (non-breaking change which adds functionality)
## How Has This Been Tested?
- Unit test cases
- Test conversations getting assigned on status change to open
- Test the job directly via rails console
