isBootstrapTranscriptContextText and getBootstrapTranscriptSuccessSource each ran
text.replace(/\s+/g,' ').trim().toLowerCase() internally. During launch the
bootstrap scan checks every transcript line against every context member for every
member's poll, so the same line was re-normalized up to (members x contextMembers)
times per cycle. Profiling a 6-member mixed launch showed isBootstrapTranscriptContextText
at ~11% main-thread JS even after the shared-parse cache.
Precompute the normalized form once per parsed line (already cached) and pass it to
both detection helpers via a new optional precomputedNormalizedText parameter. The
value is identical to what the helpers computed internally, so detection is byte-for-byte
unchanged; the helpers stay backward compatible for callers that omit it.
