sylpheed-port generalised the heading rule: an index is an amplifier, since
anything republishing headings multiplies whatever they assert. Checked mine --
INDEX.md's generated table republishes each file's H1 and Status line, a narrower
amplifier than their TOC but the same mechanism -- and then swept headings for the
dead-rule vocabulary.
The strongest hit is not a heading. ui-keyframe-time-unit.md, the Q1 page, told
readers a comparison was "Gated by SYLPHEED_KF_TIME_SHIFT=1, default unchanged"
and referred to "the other reading behind SYLPHEED_KF_TIME_SHIFT=1". That
variable was REMOVED with the record-layout fix and appears nowhere in crates/.
A reader following it sets something inert, gets default behaviour, and concludes
the two readings agree. A stale instruction that no-ops MANUFACTURES A FALSE
CONFIRMATION -- strictly worse than a stale description, and the same shape as
screen-transitions.md telling the port to author a value that is decoded.
Also demoted the section heading "and the shifted reading wins every time": the
shifted reading was itself superseded, the fix having established the same
association by a better route and timed pose 0 as well, which the shifted reading
never did. The evidence stands and is now evidence for the corrected reading.
METHOD gains three things: rank instructions above descriptions when sweeping for
stale text; an index is an amplifier; and the denominator, stated because it is
unflattering -- this corpus has 2 989 headings, 401 of which make a negative or
absolute assertion, and I have audited this session's plus the dead-vocabulary
intersection. That is a sample, not a sweep, and older headings are likelier to be
stale for having had more chances to be overturned.
