ago sat unconditional in pastReference, so "a correction was filed
moments ago" was read as reportage about some earlier day and skipped
the check. It is a natural way for a model to claim it just acted.

turnReference already carried "just now", a short-interval time phrase
rather than an exchange-noun, so the short forms belong in that set
rather than in a restructuring of pastReference. That construction
needs no lookbehind, which RE2 lacks, and costs nothing: "a while ago"
and "an hour ago" still read as reportage.

The issue named that trade as needing a human decision. There is no
trade, so there is nothing to decide.

Three false-positive rows pin the shape that was not taken, and each
one fails under a different deliberate mutation of pastReference.

fix(grounding): an interval shorter than a turn dates an event inside it #611

ago is unconditional, so a correction filed moments ago is indistinguishable from one filed three weeks ago #601
