Scan for multi-attester disagreement

emem_memory_contradictions
Read-onlyIdempotent

Find where the corpus DISAGREES with itself (algebra: competing evidence). Two or more independent sources can sign different values for the same place, band and time. This tool returns that disagreement with a severity from 0 to 1 and a citation for each disputed fact. It does not pick one value and hide the conflict. It tells you when not to trust a single answer. Read the SCOPE before you quote a zero. By default the tool counts only disagreement between two DIFFERENT attesters. One responder that answers from two upstreams counts only with include_same_attester_sources: true.

When to use: Call this before you rely on a number: 'do the sources agree on X', 'audit this claim'. Use cell_prefix for a region and band for one band family. min_severity removes small differences. Severity depends on the band kind: for a scalar, the spread over the band's range. For a vector, 1 minus the mean cosine. For a category, 1 minus the share of the mode. On a single-responder node, add include_same_attester_sources: true. There, the most likely disagreement is one signer that answers from two providers. Each record names its disagreement_scope. The receipt cites every disputed cid. To measure a pair, use emem_diff. To read the disagrees_with edge, use emem_edges_recall.

Example arguments: {"cell_prefix":"damO","band":"indices.ndvi","min_severity":0.2}

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
bandNoBand key filter (e.g. `indices.ndvi`). Omit to include all bands.
cellNoAlias for `cell_prefix`, and the spelling the rest of the surface uses for a cell64. Send a cell64 you already hold and the scan narrows to that place instead of running over the corpus.
limitNoMax contradictions to return.
cell64NoAlias for `cell_prefix`.
cell_prefixNoA cell64 to scan, or a bytewise prefix of one (e.g. `defi.zb5f9`). Omit to scan the whole corpus up to the scan cap. A full cell64 is a prefix of itself, so passing one narrows the scan to exactly that place.
min_severityNoSeverity floor in [0, 1]. 0 = report every disagreement, 1 = only flagrant. Severity scoring is per band kind: scalar (max-min over band range), vector (1 - mean cosine), categorical (1 - mode share).
window_unix_sNo[lo, hi] inclusive Unix-seconds filter on attestations' signed_at, all disagreeing attestations must fall in the window.
include_same_attester_sourcesNoAlso report keys where ONE attester answered the same address from two different upstreams. Default false, which scans only for disagreement between two or more DISTINCT attesters — so on a single-responder corpus a zero here means the narrower question was answered, not that nothing disagrees. Set true and a key qualifies when the facts differ in `derivation.fn_key` or in their `sources[].scheme` set; the same provider re-signed is a refresh, not a disagreement, and stays excluded. Each record carries `disagreement_scope` and a `providers[]` list naming what changed.
