Stop two rules reporting things that are not defects

[jepegit]

SYM-02: 158 warnings, 126 distinct tokens, most of them not acronyms

Two classes accounted for the bulk.

A word set in capitals by typography. AND, OF, AT, UNIV, TEXAS, AUSTIN, REVIEW, PAPERS — every one from a heading or a page stamp. A token whose neighbours are also capitals is a word of a phrase, not an acronym. Neighbours must be two letters or more: a lone capital beside a token is a variable, and "R equals ID IG" would otherwise suppress ID on account of the R.

A chemical formula whose subscript has already been spoken. CH two, SO four, PO four, PF three, WO three, YH three, HNO three. Expanding one is not a thing anyone can do.

The spoken number is what makes this safe to act on: CV and PC are element runs too — carbon-vanadium, phosphorus-carbon — and they are real acronyms (cyclic voltammetry, propylene carbonate) that are never followed by a subscript. Both are tested as must-still-fire.

And it reports on the first occurrence that is a use. Reporting on the first occurrence full stop meant an acronym whose first appearance was inside an all-caps heading got skipped entirely — which hid ATR and SBR, both genuinely never expanded and both used in running prose further down.

SENT-02 was half right, and the other half was a planner bug

Nine warnings. Four were harmless: two consecutive sentences of a paper, quoted in two consecutive beats.

"…as observed in one experiment and will be discussed in further detail. It can be difficult to distinguish between hydroxide, peroxide and oxide…"

The listener heard the referent three seconds ago. The rule's own description says "whose antecedent is in another beat" — and the check never looked at the beat before.

Five were real, and every one was a boundary the planner chose:

"Still on synthesis. This is apparent in the superior cycling of the cell…"

A transition and a pause now stand between the pronoun and the thing it points at. All five came from _split_oversized, where _cut_point already declines to separate a prompt from its answer and now declines this too; _segment defers the same way when the clock allows.

The judgement both need lives in one place, mimem.verbalize.cohesion — because whether such a sentence is a defect is not a property of the sentence at all. It is a property of what the programme puts in front of it.

SENT-02's five real cases are now absent from the audio rather than merely unreported.

13 new test cases in tests/unit/test_cohesion.py and test_artefact_lint.py, most of them guards. The SENT-02 trigger in test_rule_triggers.py moves its pronoun into its own segment, which is the shape that is actually a defect.
