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.

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.
