+# ── The identity that falsified this milestone (#3668) ─────────────────
+#
+# `rule_usage.surfaced` == `pre_tool_rule.cleared` + `write_path_rule.cleared`.
+# Milestone #379 was scoped on a reconstruction that put ~64% of ranked rule
+# surfacings as never reaching `rule_usage_events`. Five steps were planned
+# against it. One read of this identity — 17 = 17, then 39 = 39 on a second
+# window — falsified the whole thing: the gap was two counters that started
+# recording on different days, not a write path dropping rows.
+#
+# So the identity is not a nice-to-have. It is the cheapest true statement
+# available about this pair of tables, and its absence is what let a magnitude
+# that merely LOOKED wrong survive a code review and a five-step plan. An
+# identity that must hold exactly beats a magnitude that looks wrong.
+#
+# WHY THE ARM IS THE RIGHT PLACE TO PIN IT, and the readout is not. Inside an
+# arm, one `fresh` list feeds both recorders in one function, so the counts
+# cannot legitimately differ — at any limit. The readout-level form is weaker
+# than it looks: `cleared_threshold` counts CALLS that beat the bar while
+# `surfaced` counts RULES, and those coincide only while `RULEHINT_LIMIT` is 1.
+# Raise the limit and the readout identity breaks while nothing is wrong.
+# `RULEHINT_LIMIT` has already moved once (2 → 1, `2385100`), and that move is
+# half of why the original reconstruction misread its own numbers.
+#
+# Hence three hits below, where production currently returns at most one. The
+# test is deliberately in a state the limit does not permit today, because what
+# is being pinned is that the two recorders read the same list — not that the
+# list happens to be short.
