Classify extrusion into model vs. housekeeping and return the model bounds + confidence (DD-026 D4).
Precedence per extrusion segment:
explicit housekeeping role / wipe → excluded (beats membership: a tower inside an open object
bracket is still a tower, RR-007 §8 rule 1);
with a membership channel, object == 0 → excluded (not a member — catches an unmarked prime);
with a membership channel, object != 0 → model;
without a membership channel, anything not excluded by rule 1 → model (role fallback).
Confidence: known when a membership channel drove it; inferred when only role exclusion applied;
unavailable (empty bounds) when there was neither membership nor any excludable role — the file is
genuinely unclassifiable and framing must fall back + disclose.
