(:any (list c1 c2 ...)) compiles to Prolog disjunction (g1 ; g2 ; ...), completing
the condition boolean algebra (AND via :when list, :not, :any). cond->goal
recurses so combinators nest arbitrarily; the proof tree shows the compiled
disjunction verbatim. Maps onto Prolog's control constructs rather than
reimplementing boolean logic in SX. +10 tests.

Reports gain an :at tick (deterministic, supplied). mod/decide-temporal counts
reports about a subject within [now-window, now], asserts burst_count/2, and a
(:burst-at-least K) rule fires only on a real burst. 3 reports at 10/11/12 → hide;
3 at 1/2/12 (window 5) → keep, while the plain count rule escalates both. Fifth
report field threaded through rebuild helpers, non-breaking. +15 tests.

(:reporters-at-least N) compiles to setof(Br, report(_, Br, Sr), Bsr),
length(Bsr, Nr), Nr >= N — counts distinct reporters, not raw reports.
mod/decide-quorum asserts every report's report/3 fact (base engine scopes to the
decided report) so Prolog can aggregate reporters. One user filing 3 reports stays
:keep under quorum while the count rule escalates. Own suite. +9 tests.

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.

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.
