The Mind is about whether universities grow or shrink due to AI over the next 20 years. The current facet is "Labor market signaling — do degrees lose signaling value?"

I need to file ONE note: a single dated claim, with a # title that is the claim in one line, 1-3 short paragraphs, ending with "What would change this: …"

The session substance covers a lot, but the facet is labor market signaling. The most recent filed note (Note 8's trailing content) was the signaling split claim. But I need to identify what's NEW in this session's substance that adds a durable claim beyond what's already filed.

Looking at the "Substance from this session" section, there are several chunks:

1. Signaling split: degree signal SPLITS — competence half vs. diligence/trust half. Trust-bearing roles keep degrees; licensure pins ~20% of US employment; 2035 prediction: postings fall from ~40% to ~25-30%; degree survives as trust credential not competence credential.

2. Signaling value tracks acquisition cost — AI makes competence demonstrations cheap to fake, so demonstrations lose sorting power; degree remains expensive; scissors effect: elite premium widens, mass-degree premium compresses toward zero; bimodal wage premium distribution; shrinkage lands on competence-only schools. This "reverses the naive story."

3. Signaling migrates in-house to the university as verification — degree repriced from sorting device to trust warranty; survivors are those with proctoring capacity and brand worth underwriting.

4. Cost-structure claims (sorting mechanism, cost-mix asymmetry, labor-substitution sequencing) — these are the cost facet, already potentially covered by filed notes.

5. Demand-shift claims (youngest-edge scissors, financing layer as transmission channel) — the demand facet.

6. Regional scissors claim — regional facet.

7. Signaling claim first pass: degree does two jobs — ex post certification (dies fast) vs. ex ante screening (decays slowly); sheepskin splits.

The current facet is "Labor market signaling — do degrees lose signaling value?"

What's already filed (from Note 8's deliberation summary):
- Degree survives as trust/insurance credential, not competence credential
- Screening vs insurance decomposition: screening dies first; insurance sticky
- Signaling migrates upward to selectivity/brand
- Elite degrees gain value BECAUSE verification
- Scissors/youngest edge: new-grad premium flattens first
- Selection-based signals AI-proof; certification-based not
- Degree repriced from entry ticket to exit credential / trust warranty by ~2035

So much of the signaling substance is already filed. What's genuinely NEW in this session?

The most distinctive new element is chunk 2: **the cost-of-faking mechanism**. "Signaling value tracks acquisition cost, not content — AI pushes against the naive prediction, not with it. A signal only sorts people when it's differentially costly to acquire. AI makes competence demonstrations cheap for everyone... As the cost of faking 'competence' drops toward zero, those demonstrations lose sorting power... The degree remains expensive... so employers revert to the hard-to-fake tier. Consequence: a scissors effect, not a collapse. Stated degree requirements fall while the wage premium splits — elite-degree premium widens... mass-degree premium compresses toward zero... the degree wage premium distribution becomes bimodal."

This is a genuine mechanism claim: signals sort by differential cost; AI collapses the cost of cheaply-assayable competence signals (portfolios, résumés, test scores?) making them worthless, while the expensive-to-acquire signals (selective four-year persistence, licensure) become relatively MORE valuable. The result is not the death of the degree premium but its bimodalization — elite premium widens, mass premium compresses. This is testable in 2035: bimodal wage premium distribution.

The file already has "elite degrees gain value BECAUSE verification makes mid-tier signals redundant" and "signaling migrates upward to selectivity/brand." The bimodal scissors claim is related but the *mechanism* (cost-to-acquire / cost-to-fake) is new and sharper. It's a distinct causal claim: signaling value is set by acquisition cost, not content; AI doesn't obsolete degrees, it obsoletes *cheap* credentials — which is what mid-tier comprehensives sell.

Chunk 3 (verification in-house, trust warranty) — already filed ("degree survives as insurance," "verification survives").

Chunk 1 (trust split) — Note 8's trailing content filed the signaling split ("Degree signaling erodes by sector, then stratifies by institution" — wait, that's Note 3). Actually looking at the notes: Note 3 (filed) is "Degree signaling erodes by sector, then stratifies by institution (2025–2045)". And the last turn's substance included the trust split.
