(: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.

mod/subject-sanctions counts prior hide/remove/ban decisions about a subject from
the append-only audit log; mod/decide-escalating upgrades a sanction to :ban when
the subject has >= k priors. Non-sanction outcomes (keep/escalate) pass through.
Closes the loop between audit and policy — the trail feeds future decisions. Own
suite. +19 tests.

mod/decide-strictest collects every proven rule (pl-query-all) and applies the
harshest action by mod/action-severity (keep<escalate<hide<remove<ban), an
alternative to the engine's first-match precedence. Diverges from first-match
exactly when rule order and severity disagree. Same decision shape + :strategy;
engine untouched. Own suite. +14 tests.

Static analysis of a policy without running the engine: mod/unreachable-rules
flags rules after an unconditional rule (dead under first-match precedence),
mod/has-catchall? checks total coverage, mod/duplicate-rule-names + mod/rules-ok?
give a well-formedness verdict policy authors can assert. Own suite. +14 tests.

mod/related-ids and mod/reporters-of find reports about a subject via a Prolog
relational query (report(Id, _, 'subject')) — the policy substrate reused for
retrieval. mod/dedup-reports collapses identical reports by a normalized
reporter|subject|reason key; mod/distinct-reporters-of counts unique reporters.
Own suite (tests/link.sx). +12 tests.

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.

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.

Cross-instance reports ingest into the local registry with origin tags; the
engine decides them unchanged. Decision sharing pushes to a mock fed-sx outbox
(mod/fed-send! is the transport seam). Trust is advisory by default: a peer's
decision binds locally only under (mod/trusted? peer :mod), else it lands in the
advisory log unapplied. Revocation composes with the Phase-2 proof model —
fed-revoke-if-invalidated re-runs the engine and undoes moderation only when the
action no longer holds (exoneration flips hide→keep → revoked + origin notified).
+26 fed tests. Full mod-on-sx roadmap complete.

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.
