 verified set; the other 271 are unaudited, and most are probably fine, which is
 exactly why nobody will check them.

+## Nothing checks the prose a tool prints or documents beside its own numbers
+
+`sylpheed-port` found `verify-capture`'s note saying a capture was *"rendered with
+authored initial focus"* — an assumption nothing had established, sitting under
+their most-quoted residual. Their point: **an assumption in a harness note is
+invisible in a way an assumption in a `why` is not.** `audit-kinds` checks every
+authored value for a citation; nothing checks a tool's own prose.
+
+✅ **Swept my printed output and found no instance**: 38 lines assert a screen or
+game fact, and the ones that assert rather than report are computed in the same run
+(`"(nothing moves under this input that is quiet at rest)"` prints only when the
+index is empty). ⚠️ Weak sweep — keyword-matched, printed strings only, and "does
+this assert something the run does not establish" is a judgement, not a test.
+
+🔴 **But the class is real here and I have a known instance on the larger surface:
+tool DOCSTRINGS.** `ring_row.py` documented its calibration as
+`capture_y = 49.5 + 1.060 * design_y` — **wrong**, fitted against `menu_focus.py`'s
+approximate rows rather than the disc's. It sat in the file that underpins every
+focus finding, and it was found by accident while chasing something else, not by
+any check.
+
+📌 **The surface is bigger than harness notes.** These tools carry long docstrings
+full of factual claims about the game — calibrations, thresholds, what a screen
+does — and **nothing verifies any of it**. A `why` in an authored file at least has
+a convention demanding a citation. A docstring has nothing, is read as authoritative
+by the next reader, and travels with the code.
