Crystal Geyser metadata: qualify CPR lipid dependence and pressure-adaptation claims #1366

Non-graph follow-up for CommunityMech:000252.

The top-level description presents increased unsaturation as established pressure adaptation; the main body reports depth-associated lipid patterns and a proposed pressure explanation without a pressure manipulation. CPR taxonomy notes assert inability to synthesize membrane lipids and use SYNTROPHIC_PARTNER, although the paper does not demonstrate product-removal syntrophy and leaves unknown/ACP-independent pathways possible for some Nealsonbacteria. The broad co2-fixing bacteria/archaea taxonomy note asserts membrane-lipid contribution to CPR partners, conflating a producer pool with a demonstrated donor relationship. Related-ingredient explanations similarly turn inferred lipid sourcing and pressure adaptation into facts.

Acceptance: separately qualify these non-graph statements against the complete primary Results/Discussion, preserving the measured isotope/lipid/genome findings and canonical broad taxon records. Distinguish CPR bacterial lipid proposals from the separate Altiarchaeota/Huberarchaeota discussion. Do not replace broad groups with exact taxa or assert new donor/recipient relationships without grounding and direct evidence. Add focused validation, curation event/history and regenerated pages. A graph-only repair does not close this metadata issue.
