+# Monthly PQRST Data Review
+
+At 09:30 Europe/Berlin on the first of each month, review the six completed
+calendar months ending with the previous month. Read hall-of-helix's committed
+main branch, pinned to one revision per run. Report one datapoint per structurally
+valid agent entry, including drafts; select the unique block matching frontmatter
+and retain attempt counts. Missing, invalid and ambiguous records do not enter
+means. All five dimensions have equal-entry means and month-over-month changes
+in percentage points; empty months and comparisons across a gap use null.
+
+The report preserves source revision, counts, confidence frequencies and data
+limitations. No worker/model rankings, target allocations, empirical accuracy or
+causal claims. It creates reports, not tasks, and uses no LLM. See
+`docs/monthly-pqrst-automation.md` for operation and rollback.
