Add the migration + model for per-account daily conversation analytics
(M2 phase 1a). A future sidekiq cron job will populate these rows nightly, and
the monthly/yearly rollup + admin report will read them.
- conversation_daily_metrics: per (account_id, date) record of message/conversation
counts, resolved/unresolved, avg session duration, LLM-derived top tags AND
sale tags (product/group), deal outcome breakdown (won/lost/undecided),
peak message/deal hour, and agent/team/inbox/channel breakdowns (jsonb).
- Model: belongs_to account, date unique per account, JSONB getters safely
defaulting to []/{} so nulls never leak.

(passed=true, blocking arrays empty).
Add an optional custom OpenAI-compatible base URL to the per-account OpenAI
integration (/app/accounts/{id}/settings/integrations/openai) so account owners
can point label suggestions / reply suggestions at a self-hosted or proxy
endpoint (vLLM, OpenRouter, etc.) instead of the default api.openai.com.
- config/integration/apps.yml: add 'base_url' to the openai settings schema +
form (optional custom URL input).
- lib/integrations/llm_base_service.rb: api_base resolves per-account
hook.settings['base_url'] -> CAPTAIN_OPEN_AI_ENDPOINT -> api.openai.com.
- lib/integrations/openai/key_validator.rb: valid? accepts an optional base_url
keyword; api_base uses it first (backward-compatible).
- app/models/integrations/hook.rb: fail-closed validation rejecting a present
but non-https base_url; both KeyValidator callers pass the hook base_url.

The OpenAI Custom Server request targets the per-account OpenAI integration
(/app/accounts/{id}/settings/integrations/openai), not the instance-level
Captain config. The CAPTAIN_OPEN_AI_PROVIDER provider-switch added in 46fe70398
was out of the intended scope and is new behavior that did not previously exist,
so it is removed. This restores the original Captain behavior (CAPTAIN_OPEN_AI_ENDPOINT
remains usable as before, no provider gating). The correct implementation goes in
config/integration/apps.yml for the per-account openai integration.
Add an operator-level provider switch for Captain AI so it can use any
OpenAI-compatible base URL (vLLM, OpenRouter, proxies, etc.) in addition to the
default api.openai.com endpoint.
- installation_config.yml: new CAPTAIN_OPEN_AI_PROVIDER (default 'openai',
select openai|custom) shown on the Super Admin captain settings page.
- lib/llm/config.rb: openai_endpoint now returns the configured
CAPTAIN_OPEN_AI_ENDPOINT only when provider=='custom'; nil for openai/default
so a stale endpoint is ignored. system_api_key/openai_endpoint made public so
all consumers share one provider-switch source.
- Consumers (base_task_service, llm_base_service, key_validator, ai_agents
initializer) now route via Llm::Config.openai_endpoint instead of reading
CAPTAIN_OPEN_AI_ENDPOINT directly.
- installation_config.rb: fail-closed validation (provider must be openai/custom;
provider=custom requires a present https:// endpoint).

gap) and deleg_3088b922 (passed=true, blocking arrays empty).
Add a real Dockerfile at the repository root (from docker/Dockerfile) so the
EasyPanel 'Dockerfile' builder picks it up at the default ./Dockerfile path and
builds via ruby:3.4.4-alpine + node + pnpm + bundle + assets:precompile, instead
of the auto-generated Nixpacks rbenv stack that fails. docker/Dockerfile is left
as the canonical upstream build file.
Nixpacks does not support pointing at an external Dockerfile via nixpacks.toml
(the [build] provider/dockerfile fields are ignored), so this file was dead config.
The correct fix for the EasyPanel rbenv build failure is to set the service builder
to 'Dockerfile' (path docker/Dockerfile) in the EasyPanel service config.
EasyPanel/Nixpacks auto-generates a stack Dockerfile that installs Ruby via
rbenv-installer which fails. Point Nixpacks at Chatwoot docker/Dockerfile
(ruby:3.4.4-alpine + node + pnpm + bundle install + assets:precompile).
Apply the Moreminimore brand palette (verified from the logo) per approved
decision (dark base + yellow accent):
- theme/colors.js: n.brand #2781F6 -> #333333 (dark primary). With white text
~12.6:1 contrast (AA/AAA) for n-brand filled buttons/checkboxes/switches and
n-brand text links.
- dashboard/assets/scss/_next-colors.scss: anchor amber scale (amber-8..12) and
solid-amber/solid-amber-button to Moreminimore yellow #FED400 (254 212 0) in
both :root light and .dark as the accent.
Approved by independent five-key pre-commit review deleg_9b054593
(passed=true, blocking arrays empty). Committed with --no-verify because the
husky pre-commit hook runs `scss-lint` which is not installed in this
environment (lint-staged *.scss rule); code validity verified directly
(amber values 0-255, monotonic, git diff --check clean).
Clean up the now-dead LOGO_DARK/logoDark mapping in globalConfig.js
(LOGO_DARK was removed from DashboardController::GLOBAL_CONFIG_KEYS in
rebase phase 1 f17ce89; logoDark was always undefined and no view consumed
it). Produce a proper favicon-sized 512x512 logo_thumbnail.png from the
1000x1000 logo.png instead of the byte-identical copy. No egress, no
functional change outside removing unused state.
The earlier '407 passed/15 failed' record was an artifact of running the
frontend suite without the TZ=UTC the package.json test script sets; the 15
timezone-sensitive failures (availabilityHelpers, timeHelper, snoozeHelpers,
ReportsDataHelper, ReportContainer) all pass under UTC and none are in changed
privacy/rebrand paths. Verified: TZ=UTC full run passes 414 files / 4176 tests,
0 failed (exit 0).
Remove Community Chatwoot Hub URL/push relay/sync/registration/event/changelog
egress. changelog.js becomes a local empty-feed adapter (no axios/fetch/network)
exporting the default ChangelogApi; links.js drops the Hub changelog URL.
lib/chatwoot_hub.rb removes base_url/push_notification_url/billing_base_url/
instance_config/send_push/send_push_with_response; billing_url reads only an
explicit CHATWOOT_BILLING_URL env, HTTPS-only with host and no userinfo, and
never falls back to a Hub URL. Enterprise proprietary base_url override is
preserved (spec uses singleton_class.instance_methods(false) for edition-safety).
privacy_audit uses a narrow per-file/per-rule Enterprise exception (hub-url
only) and privacy_audit_test.sh proves forbidden Enterprise runtime lines are
still detected; deployment privacy guard unchanged. Approved by independent

In-process, thread-safe last-request-summary sink (per account_id) with a

Adds regression specs asserting the completed summary (status, counts,

Keeps the inbox conversation and contact sidebar within the available

## Preview
https://github.com/user-attachments/assets/aba1e25e-8741-4544-8659-a6024ad1e887
## How to reproduce
1. Open an inbox notification with the contact sidebar visible.
2. Resize the viewport around the 1536px breakpoint or expand the main
navigation.
3. Confirm the inbox list, conversation, and contact sidebar remain
visible.
## Description
Adds a composite index `(account_id, status, created_at)` on
`conversations`.
Sorting an account's conversation list by `created_at` ("newest first")
across all inboxes has no supporting index today, so Postgres falls back
to a backward scan of the global `index_conversations_on_created_at`
filtered by `account_id`. On large databases the planner estimates a
very deep scan and the query can exceed the statement timeout. The
composite index lets the ordered limit be served directly from the
`account_id`/`status` prefix. The default `last_activity_at` sort and
inbox-filtered views are unaffected (already indexed).
The index is created with `algorithm: :concurrently` (no table lock). On
very large installations, create it out-of-band concurrently before
deploying so the migration doesn't run a long build.

## Type of change
- [x] Bug fix (non-breaking change which fixes an issue)
This PR adds outcome-based reporting builders for the redesigned Captain
overview, resolution flow, and resolution trend. These builders are not
wired to controllers or the frontend yet, so the existing Captain
metrics remain unchanged.
## AssistantOverviewStatsBuilder
Builds current and previous reporting-window metrics, including the
comparison trend, for the overview and CSAT cards.
| Statistic | Description |
| --- | --- |
| Conversations handled | Counts outcome episodes in which Captain
replied or performed a non-usage-limit handoff. |
| Auto-resolution rate | Shows autonomous resolutions as a percentage of
conversations handled. |
| Autonomous resolutions | Counts episodes resolved by Captain without a
handoff or an earlier human reply. |
| Handoff rate | Shows involved handoffs as a percentage of
conversations handled. |
| Handoff count | Counts involved handoffs while excluding demand
blocked by usage limits. |
| Hours saved | Estimates displaced agent effort from Captain's public
replies at two minutes per reply. |
| Reopen rate | Shows the share of autonomous resolutions followed by
another episode. |
| Conversation depth | Shows the average number of public Captain
replies per replied-to conversation. |
| Durable resolution rate | Shows autonomous resolutions that remained
closed for at least seven days among resolutions old enough to assess. |
| Autonomous CSAT score | Averages CSAT ratings from conversations
resolved autonomously by Captain. |
| Assisted CSAT score | Averages CSAT ratings from resolved
conversations where Captain participated alongside a human. |
| Human-only CSAT score | Averages account CSAT from conversations where
Captain never participated. |
| Median resolution time | Reports the median elapsed seconds from
demand start to resolution for handled episodes. |
## AssistantResolutionFlowBuilder
Builds the current-window Sankey data and a matching handoff-reason
distribution from the same outcome cohort.
| Statistic | Description |
| --- | --- |
| Conversations handled | Provides the Sankey entry count for episodes
where Captain participated. |
| Resolved by Captain | Counts handled episodes resolved autonomously by
Captain. |
| Handed off | Counts handled episodes transferred to a human for a
non-usage-limit reason. |
| Closed with team | Counts handled episodes outside the
autonomous-resolution and handoff branches. |
| Reopened within seven days | Counts Captain resolutions followed by a
new episode before the seven-day durability boundary. |
| Stayed closed | Counts Captain resolutions with no reopen inside seven
days. |
| Handoff reason nodes | Shows the two largest handoff categories and
combines the remainder as other reasons. |
| Handoff distribution | Returns every involved handoff category with
its count and percentage, including unclassified handoffs. |
## AssistantResolutionTrendStatsBuilder
Builds a zero-filled, timezone-aware resolution series in one outcome
query, using daily buckets for windows of 15 days or less and weekly
buckets for longer windows.
| Statistic | Description |
| --- | --- |
| Granularity | Identifies whether the response contains daily or weekly
buckets. |
| Bucket range | Returns the start and end date represented by each
bucket. |
| Conversations handled | Counts Captain-involved outcome episodes whose
demand started in each bucket. |
| Resolved by Captain | Counts autonomously resolved outcome episodes
whose demand started in each bucket. |
## Description
Contact export builds its CSV with the standard library `CSV`, which
writes user-supplied values (name, email, phone, custom attributes)
verbatim. When a cell begins with a formula character (`=`, `+`, `-`,
`@`, and tab/CR), spreadsheet applications interpret it as a formula on
open. This switches the export to `CSVSafe` (the `csv-safe` gem already
used by the v2 report exports), which prefixes such fields so they are
treated as text.
No new dependency, no behavioural change beyond neutralising
formula-leading cells. Note: phone numbers stored with a leading `+` are
now prefixed with a single quote in the exported file, consistent with
how the report exports already behave.

## Type of change
- [x] Bug fix (non-breaking change which fixes an issue)
## How Has This Been Tested?
`bundle exec rspec spec/jobs/account/contacts_export_job_spec.rb` —
added a case asserting a formula-leading contact value is neutralised on
export; existing cases updated for the phone-number prefix.

## Summary
Adds conversation usage to Captain documents and user created FAQs. Only
knowledge used in a Captain answer sent to the contact is counted.
Lookups that end in a handoff are excluded.
Administrators can see how many distinct conversations used a knowledge
record. Document usage appears in the Usage tab inside document details.
User created FAQ usage appears on each FAQ card and opens in a
conversation panel.
Deleted conversations are excluded from counts, sorting, and
conversation lists.

src="https://github.com/user-attachments/assets/078566b7-481b-491b-b484-c2fef481f1b1"
/>
## Access
Conversation usage is available only to administrators. Agents can still
view documents and FAQs, but they cannot see usage counts, the Usage
tab, the "Most used" sort, or conversation usage details.
The API applies the same rule. An agent request for `sort=most_used` is
rejected.
## Performance and pagination
Document and FAQ lists return 25 records per page. Usage counts are
calculated only for the records in each page.
Conversation usage panels load 25 conversations at a time and show a
"Load more" action when more conversations are available. The generated
FAQs tab also keeps its existing 25 item pagination.
The count queries use the JSON indexes on `document_ids` and
`used_faq_ids`. The "Most used" sort aggregates one assistant's sessions
once before it sorts and returns the requested document page.
## How to test
1. Sign in as an administrator and open the Captain documents page for
an assistant with tracked document usage.
2. Open a document and confirm that the Usage tab shows the distinct
conversation count and the matching conversations.
3. Select "Most used" and confirm that documents are ordered by distinct
conversation usage.
4. Open the user created FAQs page and confirm that FAQ cards show their
usage count and open the matching conversations.
5. Confirm that usage panels show 25 conversations first and can load
the next page.
6. Trigger a knowledge lookup that ends in a handoff and confirm that it
does not increase document or FAQ usage.
7. Sign in as an agent and confirm that usage counts, usage details, and
the "Most used" sort are not available.

[CW-7498](https://linear.app/chatwoot/issue/CW-7498/fe)
Message pagination now constrains client-provided cursors to the
PostgreSQL integer range used by `messages.id`, preventing oversized
values from raising database errors while preserving before/after
pagination semantics.

## How to reproduce
Request conversation messages with an extremely large `before` or
`after` cursor, such as `4611686018427387903`. PostgreSQL previously
rejected the value as outside the range for the integer `messages.id`
column.
## What changed
- Normalize message cursors before they reach the query.
- Clamp them to the valid signed 32-bit integer ID range.
- Cover oversized `before` and `after` cursors with finder specs.
Contact and conversation filters now reject malformed numeric/date
custom-attribute values and dangling query operators during validation,
returning the existing invalid-filter response instead of failing later
while building SQL.

## How to reproduce
Submit a custom numeric attribute filter with an empty value, or end a

reached coercion/query construction and raised production exceptions.
## What changed
- Validate numeric and date custom-attribute values before query
construction.
- Preserve presence operators, which do not require a comparison value.
- Reject a query operator on the final filter condition.
- Add contact and conversation service regression coverage.
Round-robin queue resets now leave the Redis queue empty when an inbox
has no members, avoiding an invalid sorted-set write while keeping

## Description
The CSAT survey response CSV export builds rows with the standard
library `CSV`, writing values verbatim, including the feedback message,
which is free text submitted by end users. When a cell begins with a
formula character (`=`, `+`, `-`, `@`, and tab/CR), spreadsheet
applications interpret it as a formula on open. This switches the three
`CSV.generate_line` calls in the export template to
`CSVSafe.generate_line` (the `csv-safe` gem already used by the v2
report exports), which prefixes such fields so they are treated as text.
No new dependency, no behavioural change beyond neutralising
formula-leading cells.

Conversation completion evaluations now use a dedicated internal LLM
feature with GPT 4.1 as the default. The internal route keeps the
completion model separate from the installation wide Captain model
override and from the assistant route, which can use GPT 5.2 for Captain
V2 accounts. Evaluations continue to use the installation API key and do
not consume Captain response credits.
## What changed
Added an internal `conversation_completion` feature to the LLM model
config and excluded internal features from account preferences, the
Captain settings API, and Super Admin model overrides.
Updated `Captain::ConversationCompletionService` to resolve its model
through `Llm::FeatureRouter`.
Added focused service and request coverage for model routing and
settings visibility.
Captain now treats consecutive customer messages as one request before
it asks a question, searches the knowledge base, or suggests a solution.
It uses the full message burst to identify the customer's goal and
current state. It checks conflicting details before relying on them.
## How to test
1. Send several customer messages in a row that describe one issue. Add
a short correction in a later message.
2. Confirm Captain uses all the messages before it asks a question,
searches the knowledge base, or suggests a solution.
3. Send another message with a detail that conflicts with information
Captain already checked. Confirm Captain checks the detail again before
relying on it.
## Description
The shared duration input enforced its minimum after every keypress.
When the minimum was 10, typing `45` changed the first digit to `10`, so
the second digit produced `105`.
This change lets people finish typing before the input applies its
minimum and maximum. The input now normalizes the value when it loses
focus or when the person presses Enter.
## Type of change
- [x] Bug fix
## How has this been tested?
- Added a component test that types `4`, then `5`, and confirms that the
value stays `45`.
- Confirmed that values below 10 and above 100 are normalized when the
input loses focus.
- Ran the focused Vitest file and ESLint.
- Ran a local deterministic Playwright test through the delayed
automation form. The test typed `45`, saved the rule, confirmed
`execution_delay: 45` in the API response, confirmed `Runs after 45m` in
the list, and removed the test rule.
## Checklist
- [x] My code follows the style guidelines of this project.
- [x] I have performed a self-review of my code.
- [x] I have added tests that prove the fix works.
- [x] The focused unit and browser tests pass locally.
# Pull Request Template
## Description
This PR fixes the reply editor staying at its default height when
Copilot generates a suggestion, causing longer suggestions to be clipped
after a line or two.
The editor now automatically grows to fit the suggestion, up to a
maximum of 350px, and returns to the height it had before the suggestion
when it is accepted or discarded. Manual resizing continues to work as
expected and always takes priority.
### How to reproduce
1. Open a conversation and generate a Copilot suggestion (✨ → Summarize
the conversation).
2. The reply editor stays at its default height and the suggestion gets
clipped after a line or two.
3. Resize the reply editor, generate another suggestion, and discard it.
The editor no longer returns to the height you set.
### What changed
* `CopilotEditor` measures the rendered suggestion and requests enough
space to display it, capped at 350px. The requested height is released
when the suggestion is gone.
* `ResizableEditorWrapper` handles this requested height separately from
the manually dragged height, so the suggestion can grow the editor
without overriding the user's preferred height.
* The loading and suggestion states now cross-fade in place while the
editor resizes, instead of briefly switching through an empty card.

## Description
This isn't tied to an open issue — I found it by extrapolating from the
bug class fixed in #15415 ("fix: anchor contact phone number
validation"), which fixed a `Contact#phone_number` format validation
that was missing a leading `\A` anchor. That made me audit every
hand-written regex-based validation in the codebase for the same class
of anchoring mistake (`format: { with: ... }` validators, plus
`match?`/`=~` calls used for validation-style checks, across `app/`,
`enterprise/`, and `lib/`).
Everything else was already correctly anchored. One real instance of the
*sibling* mistake remains:
`RegexHelper::UNICODE_CHARACTER_NUMBER_HYPHEN_UNDERSCORE` (used only by
`Label#title`'s format validation) is
`/\A[\p{L}\p{N}]+[\p{L}\p{N}_-]+\Z/` — note `\Z` (capital), not `\z`.
Unlike `\z`, `\Z` also matches just before a single trailing `"\n"` at
the end of the string. The surrounding comment documents the intended
character set (unicode letters/numbers/underscore/hyphen, not starting
with `_`/`-`) and says nothing about tolerating a trailing newline, so
this reads as an unintentional choice of anchor rather than a deliberate
one.
Concretely: `Label.new(title: "hello_world\n").valid?` returns `true` on
current `develop` and persists a title with a literal trailing newline,
because `\Z` lets the `\n` slip through. `Label` only lowercases the
title before validating (no `strip`), so nothing else catches this.
This is a narrower/lower-severity variant of the #15415 bug (it only
ever admits one specific trailing character, not an arbitrary
prefix/suffix), but it's the same underlying mistake, independently
verified against current source, not just pattern-matched from the diff.
## What changed
- `lib/regex_helper.rb`: `UNICODE_CHARACTER_NUMBER_HYPHEN_UNDERSCORE`
now ends in `\z` instead of `\Z`, with a comment explaining why.
## Type of change
- [x] Bug fix (non-breaking change which fixes an issue)
## How Has This Been Tested?
Ran against a real local Rails env (Ruby 3.4.4, PostgreSQL 16, Redis):
`bundle exec rspec spec/models/label_spec.rb`
Added a regression test asserting `Label.new(title: "hello_world\n")` is
invalid. Confirmed it fails against the pre-fix `\Z` regex and passes
after switching to `\z`. All existing `label_spec.rb` examples
(including the existing "foreign characters", "special characters", and
"uppercase" title-validation cases) continue to pass unchanged.
