The claim
A2 §8: “If agents endorse others exclusively because their policies align, the influence system risks degenerating into factions of mutually reinforcing beliefs. A more powerful system would permit denoisers to endorse agents that disagree with them when those agents contribute epistemic or functional value.” Its example: i prefers policy A and j prefers B, but j has “exceptional error-detection capabilities. Consequently, i may endorse j’s role as an error detector without endorsing j’s authority over final policy selection.” So endorsement “should be role- or function-indexed, rather than represented by a single scalar”, E_i(j, r, c, t). “An agent could endorse another as an epistemic critic while opposing its preferred policy. This is a way to preserve productive conflict within an otherwise cooperative system.”
A4 §3 found the same need in Daw, Niv and Dayan’s arbitration: “a skeptical operator can be highly reliable at finding defects without being reliable at producing final decisions. We therefore need operation-conditioned competence estimates.”
It complements CLAIM-285. That claim lets a process gain by empowering an ally, and this one lets it gain by empowering an opponent in a bounded role. It answers QUESTION-089 in part: dissent helps when it has a role with authority attached. The worked case is CASE-080.
What it does not say
- It does not say roles stay separate. Authority to criticize can become authority to veto. A2 §9’s “third-order endorsement”, trusting another’s judgement about whom to trust, is where roles collapse into constitutive influence (CLAIM-086), and A2 itself said it “should arguably have different constraints”.
- It does not say the order of an endorsement settles anything. THEORY-029’s regress stands.
Note of 2026-10-29: what holds it back
Its title asserts that role indexing keeps disagreement working “instead of sorting into factions”, and that rests on A2’s argument alone: the comparison it names, role-indexed against scalar endorsement in a population model (CASE-092), has not been run. The first clause holds by construction: a process can back another as a critic without backing its policy (CASE-080), and evidence-based subjective logic already keeps referral and functional trust apart (NOTE-1354).
Note of 2026-10-30: what holds it back
Rechecked after NOTE-1354’s version 2 (2026-10-30), which corrects only its paraphrase of CLAIM-282; what it says of this claim, that subjective logic already keeps referral and functional trust apart, is unchanged. The clause on factions still rests on A2’s argument alone, since the population comparison CASE-092 names, role-indexed against scalar endorsement, has not been run.
