This is a "Mind" note-taking system. The overall question: Do Universities grow or shrink due to AI? Current facet: Enrollment demand shift (credential value vs. AI skills).

Prior notes already filed include Note 7 (shown in full) which is exactly on this facet: "## Enrollment demand shift: credential value vs. AI skills (2025)" with the barbell claim.

The session substance at the bottom is a long batch of claims:
1. Enrollment demand shift claim — bifurcation by credential content, general/liberal-arts-only credentials at non-elite schools demand falls 20-40%, Sun Belt growth masks credential-value erosion.
2. Regional variation claim — the SEC/Sun Belt vs NE/Rust Belt two-regime claim (already filed as Note 1 per the first message).
3. Labor market signaling claim — the three-mechanism collapse of degree's monopoly on first-job screening (already filed as Note 2 per the second message).
4. Eight independent signaling claims batch (signaling economics, entry-level, legal-infrastructure, pricing corollary, graduate-gatekeeping, export-education, network-decoupling, falsifiability).
5. Substitution-asymmetry claim — attestation-rich vs attestation-poor regions.
6. Cost-structure claim — AI attacks variable cost, fixed costs intact, two revenue props break.
7. Substitution/wage-compression cost claim (the JSON thought).
8. Six cost-structure claims batch.
9. Cost-structure claim 7 (bottom line): spending redirects, not shrinks.
10. Research-function wind-down planning lines.
11. Enrollment-facet claim, ready to file: barbell polarization claim.

The current facet is "Enrollment demand shift (credential value vs. AI skills)". So I should file a note for that facet.

The last line of the session substance — "Enrollment-facet claim, ready to file" — is the enrollment demand claim: AI compresses the signaling value of the generic bachelor's degree faster than admissions pipelines adjust, so 2030s enrollment polarizes into a barbell — selective flagships/R1s hold or grow, non-selective regional publics and small privates without an industry anchor shrink fastest. Regional divergence is real but demand-driven: Sun Belt/SEC grow on demographic flows and employer relocation, not because AI raises degree value. AI-skill micro-credentials complement degrees at the top but fail to stabilize the bottom.

But Note 7 (already filed) is almost exactly this claim. The prior-filed Note 7 says: "US enrollment therefore polarizes rather than uniformly shrinks... Top of the market holds... Bottom of the market thins... Regional divergence is demand-mix, not AI alone... Micro-credentials are a middle-market illusion."

Hmm. So what's the increment here? The question for this note-filing: what's genuinely NEW in this session relative to the filed Note 7?

The session substance contains a lot. But much of it was already filed (the regional claim per Note 1, the signaling claim per Note 2, the cost-structure claims per Notes 3/5, the spending-redirection claim per Note 5). The enrollment-facet claim at the end is nearly identical to Note 7.

Wait — but the user's prompt structure: "Current facet: Enrollment demand shift (credential value vs. AI skills)" and "Notes already filed: Note 1 ... Note 2 ... Note 3 ... Note 4 ... Note 5 ... Note 6 ... Note 7 ..." — the "Notes already filed" list shows the prior filing history. The task is to file the next note for the current facet based on the session substance.

Given the session substance ends with "Enrollment-facet claim, ready to file: AI compresses the signaling value of the generic bachelor's degree..." — this is the claim to file. But is it new relative to Note 7?

Note 7 (filed) already covers: barbell polarization, top holds, bottom thins, regional divergence demand-driven, micro-credentials illusion.

The ready-to-file claim adds: "AI compresses the signaling value of the generic bachelor's degree faster than admissions pipelines adjust" — the timing/asymmetry framing. And "non-selective ... without an industry anchor shrink fastest" — the industry-anchor criterion. Actually Note 7 said "no anchor industry or demographic tailwind" — already there.
