ultra-v0.6.8 below-cap reuse-5: the memory frontmatter parser (frontmatterOpenIndex in internal/core/memory/yaml.go) trims lines with strings.TrimSpace, which does not strip U+FEFF, while the record-lint parser uses frontmatter.TrimBOM, so a BOM-led memory page is a page with frontmatter to record-lint and a page without it to memory. Pre-existing, not introduced by the reviewed slice.

Grounds

• pursued: every memory frontmatter reader shares frontmatterOpenIndex, so one strip there aligns them with record-lint; a BOM-led page that textOpensFrontmatter, parseFrontmatter, splitFileFrontmatter or frontmatterKeyLine still reads as frontmatter-less would show it wrong
