Causal graphs

Aerobic thermophilic decomposition

Aerobic degradation of organic matter in compost releases heat, raising pile temperature and selecting thermophilic decomposers with polymer-degrading enzymes.

Directed graph · arrows run from subject to object. Focus or hover over a node or arrow for details; the evidence table follows.

Curation

What a curator decided about this record, and why. A record built from several source concepts can carry one decision per concept.

  1. GROUND 2026-08-13 · claude-opus-5

    Grounded to ENVO:00002170 'compost' (CLOSE). GOLD names the composting process, ENVO the resulting material; close but not exact. Path: Engineered > Solid waste > Composting (source concept habitatmech:GOLD.4741a9f8bb)

  2. GROUND 2026-08-13 · claude-opus-5

    Grounded to ENVO:00002170 'compost' (CLOSE). GOLD names the composting process, ENVO the resulting material; close but not exact. Path: Engineered > Solid waste > Composting > Oil palm (source concept habitatmech:GOLD.981cf7502c)

  3. REVIEW 2026-08-13 · claude-opus-5

    Reviewed and endorsed the seeder's own resolution. Multi-source review pass: this record is attested by more than one independent vocabulary, and this source's label or path was read against the record's ontology term to check the merge is right. It agrees. Source concepts in the same pass whose labels did not agree were re-decided rather than endorsed; see the pass's other decisions of the same date. (source concept habitatmech:PREGO.e2f1a69477)

  4. REVIEW 2026-08-15 · claude-opus-5

    Reviewed and endorsed the seeder's own resolution. Co-attestor review (#12): this source names the ontology CURIE itself, so its grounding is definitional rather than a lexical guess — the record IS the term the source pointed at. Recorded so the record it co-attests can reach REVIEWED, which needs every source concept decided. (source concept habitatmech:MADIN.87d709b6aa)
