giles	102c806451	mod: Ext 3 — human-readable proof explanation (mod/explain), 164/164 ... mod/explain renders a decision's proof tree into legible text: action + rule, evidence line, and each derivation goal with [proved]/[unproved] and the unification bindings that satisfied it (e.g. {B=ann, N=3, S=dave}). Pure SX over the Phase-2 proof data — the audit trail's 'why' made readable. +10 tests. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-06 18:06:29 +00:00
giles	779a592614	mod: Ext 2 — weighted/aggregate scoring (:score-at-least), 154/154 ... Report :signals ({:kind :weight}) project to signal(Id, 'kind', weight) facts; condition (:score-at-least N) compiles to aggregate_all(sum(W), signal(Id,_,W),T), T >= N. Low-confidence signals accumulate past a threshold via genuine Prolog arithmetic aggregation. Default policy untouched — proven via custom rule sets. +8 extension tests.

giles	2ea87796a1	mod: Ext 1 — negation-as-failure conditions (:not / :attr), 146/146 ... Report attributes (:attrs) project to attr(Id, name) facts; policy gains (:attr x) and (:not <cond>) conditions. The Prolog substrate exposes negation as a functor not(Goal) (the prefix \+ operator doesn't parse here). Closed-world example: hide spam unless author verified. Default policy untouched — feature proven via custom rule sets, so all 132 base tests stay green. +14 extension tests.
