Separate Hanford aquifer guild inference from causal flux and niche partitioning #1494

Finding

kb/communities/Hanford_300_Area_Unconfined_Aquifer_Community.yaml promotes observational community/guild patterns to measured annual electron-donor/acceptor flux and assigns NICHE_PARTITIONING to all three nodes. Two arrows imply a demonstrated community-turnover -> flux -> depth-guild causal chain that the inspected evidence does not establish.

Repair

Retain the field composition and putative-guild observations. Qualify flux and functional assignments as inference, remove the two unsupported arrows and unqualified niche-partitioning labels, and make the four existing broad canonical participants explicit without claiming they exhaust the sampled community or resolve guild members. Environmental nitrate/uranium are not demonstrated exchange. Add an anchored gap for selective causal evidence and functional measurements.

Review Scope

PMID:22456444 primary PubMed abstract and complete local selected-snippet cache read. The cache says full_text but is not a complete main body. PMC CAPTCHA and publisher/Europe PMC access failures prevented full-body verification; no CAPTCHA bypass, figure/supplement/raw-data inspection or new predation structure. Claims stay within abstract/snippet support. Source-based self-adversarial review, not independent approval. Leave open until protected main merge.
