Builds the four remaining analytics gaps from the architecture plan:
- Report library (REQ-ANL-03): new backend/reports module - saved reports
as parameterisations of the governed analytics queries (never free-form
SQL), rolling window_days filters, recorded runs, CSV export via
Content-Disposition. Reports screen gains the library card with
create/run/export/delete plus a results modal.
- Natural-language analytics (REQ-ANL-05, ADR-0010): POST /analytics/ask
maps a question onto one whitelisted intent, runs the same governed
query the dashboard uses, then narrates the numbers. Ask Analytics card
on the Analytics screen; LLM outages 503 without touching the charts.
- Time-to-hire baseline (REQ-ANL-08): KPIs surface tth_baseline_* from
org setting analytics.tth_baseline ({days,source}); not hardcoded
per OPEN-12. analytics added to org-settings categories. Reports TTH
card shows the delta when set.
- Source spend (REQ-ANL-09 cost side): hiring costs can be tagged with a
source channel; source performance returns tagged spend and
cost-per-application, including spend-only rows for channels with zero
applications (wasted spend must stay visible). Log-cost modal and
Source Performance table on Reports; untagged spend stays
cost-per-hire only.
Verified live: migration autogenerated and applied (saved_reports,
report_runs, hiring_costs.source_channel_id), 50 backend tests, vite
build + smoke/token/theme suites, and a headless-browser drive of both
screens end to end.
