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.

Pure SX state machine (lib/mod/lifecycle.sx) over the engine:
open→triaged→decided→appealed→final, transition table guards illegal moves.
Auto-tier resolves terminal actions; escalate parks at human-tier (resolve
blocked until review supplies evidence). Appeal re-runs the engine — new
exonerated-keep rule at top precedence lets exoneration override a prior hide.
Api façade (mod/triage/resolve/review/appeal/finalize) over a case registry,
logging committed decisions to the audit trail. +46 escalation tests.

Reports carry an :evidence list, asserted as evidence/3 facts; reviewer-remove
rule (highest precedence) lets human review override classification. Proof tree
built constructively by re-querying each rule body goal against the same DB with
the report id bound, so derivations carry real unification bindings. Append-only
audit log records decision + proof + evidence snapshot per decide, monotonic seq,
never mutates prior entries. +29 audit tests.
