- compileRules precomputes the full SGR open sequence per rule and per band;
wrap() is now pure concatenation, bandOpen() a table lookup (output bytes
unchanged, bg keeps its unvalidated white-fallback)
- claim() replaces the linear overlaps() scan: claimed spans stay sorted by
start, O(1) append on the common left-to-right sweep plus one binary search
otherwise (match-dense 200KB payload: -19% one-shot, -56% streamed)
- HighlightStream: bufferHasEsc flag skips the O(buffer) escape rescans when
neither the held text nor the chunk contains ESC, fixing quadratic rescan on
escape-free floods (plain 200KB streamed: -54%)
- applyHighlights tracks the consumed match budget incrementally instead of
two budgets.reduce() passes per text token
- ESCAPE_RE now covers DCS/APC/PM/SOS (BEL or ST terminated) and single-char
Fe escapes (DECSC/DECRC/NEL/RI/RIS, orphan ST); isIncompleteEscape holds cut
tails of the new families; split-smoke exercises every cut point through them
