This PR adds a Captain Assistant **Overview** page to show some KPI metrics (conversations handled, auto-resolution, handoff, hours saved, reopen-after-resolve, conversation depth) with trend deltas vs the previous window, a real knowledge card, and a lazily-loaded, cached LLM welcome summary. ### Highlights - **Two contextual banners** on the overview: - **Inbox banner** — prompts the user to connect an inbox when the assistant has none, so it can actually do work. - **Coverage banner** — warns when FAQ coverage is below 85% with more than 100 responses pending review, linking straight to the pending queue. Dismissal persists per-assistant for 24h via localStorage. - **Batched stats builder** (`Captain::AssistantStatsBuilder`) computes both windows in single FILTER-aggregated scans to cut round trips, behind new `stats`/`summary` endpoints. - **Cards included but intentionally left dummy / not rendered yet:** `ResponseQualityCard` (flagged responses) and `CreditUsageCard` (credit usage + daily chart). Credits are an account-wide counter with no per-assistant or daily history, so there is no real data to back them yet; they ship in the codebase but are not wired into the page. ### Index migration - Replaces `index_messages_on_sender_type_and_sender_id` with `index_messages_on_sender_and_created` `(sender_type, sender_id, created_at)`. - **Why it helps:** the per-assistant windowed lookups filter `sender_*` *and* a `created_at` range. The old 2-column index matched every lifetime row for the assistant and filtered the time slice at the heap (~89% of rows discarded); adding `created_at` as a range column lets Postgres scan only the window, and fixes the row-count estimate so the planner picks a hash join over a nested loop on `reporting_events`. - **Why dropping the old index is safe:** the new index is a left-prefix superset `(sender_type, sender_id, ...)`, so every query the old one served is still served. No code references it by name, and dropping it keeps write amplification on `messages` neutral. Built/dropped with `CONCURRENTLY` and `if_not_exists`/`if_exists` guards. ## Preview <img width="2572" height="1754" alt="CleanShot 2026-06-29 at 22 38 51@2x" src="https://github.com/user-attachments/assets/3798d09e-7850-48e4-b2cd-508533f15cea" /> ## Banners #### Inbox connect alert <img width="2178" height="612" alt="CleanShot 2026-06-30 at 14 26 55@2x" src="https://github.com/user-attachments/assets/373c371c-bb7d-4291-a0f9-620673078302" /> #### Coverage alert <img width="2178" height="612" alt="CleanShot 2026-06-30 at 14 25 41@2x" src="https://github.com/user-attachments/assets/e12d6308-11b6-4ba2-88a2-8a3077dd3e8f" /> --------- Co-authored-by: Sivin Varghese <64252451+iamsivin@users.noreply.github.com>
