+intents plus validated parameters, and (2) narrate the numbers the governed
+query returned. Every figure in the answer therefore comes from the same read
+layer the dashboard renders, and a prompt-injected question can at worst pick

+"""Executes a report definition against the analytics read layer.
+
+A report is a saved *parameterisation* of the same governed queries the
+dashboard runs — never free-form SQL. That keeps ADR-0010's constraint intact:
+adding a report type means adding a builder here, not opening a query surface.
+
+Every builder returns the same tabular envelope so one DataTable and one CSV
+writer can render any report type:
+
+    {"columns": [{"key", "label"}, ...], "rows": [dict, ...]}
+
+Filters accept either explicit ISO `from_date`/`to_date` bounds or a rolling
+`window_days`, resolved at run time. Rolling is the default a saved report
+wants — "last 90 days" should mean the last 90 days on every run, not the
+quarter that was current when the report was saved.

    parallel. There is no group-by endpoint, but `department` is a filter on
    every analytics route, and one KPI payload carries all four columns at once.
 
-   THE REPORT LIBRARY IS GONE. Six cards that fired a toast and generated
-   nothing is worse than an honest note: there is no report-generation or export
-   endpoint on the backend, so the grid was removed rather than left to imply
-   otherwise. In its place is the real cost ledger those reports would draw on.
+   THE REPORT LIBRARY IS REAL NOW (/reports/*). A saved report is a stored
+   parameterisation of a governed analytics query — a report type plus a
+   rolling window — run and exported (CSV) server-side, with every run
+   recorded. An earlier grid of six cards fired a toast and generated nothing;
+   the library only returned once the endpoints existed.
+
+   SPEND ATTRIBUTION: a hiring cost can be tagged with a source channel, which
+   feeds the cost-per-application column of Source Performance. Untagged spend
+   deliberately counts toward cost-per-hire only — folding it into a source
+   would fabricate a ROI figure.
+
+   TTH BASELINE (REQ-ANL-08): the KPI payload carries tth_baseline_days only
+   when the org setting `analytics.tth_baseline` is set, with provenance. No
+   setting → no baseline shown; the 27-day BRD figure is not hardcoded here.
