This is a full consolidation/synthesis. I need to produce ONE Markdown note that is the current best statement of what is established across all the filed notes. Start with a # title (one line — presumably the core claim), then short paragraphs, then "What would change this: …" line. Keep sources or Unverified tags. Don't mention tools, sessions, or revising.

Let me inventory the durable claims across all 16 notes:

**Core answer:**
- "Grow or shrink" resolves as "both" — the system bifurcates/thins, not uniform. Region- AND stratum-specific.
- Total enrollment drifts ~19M → ~14–15M by 2045 (Unverified forecast); degrees conferred may rise slightly while institution count falls sharply.
- System "thins, doesn't shrink": total degrees roughly steady, median campus shrinks, institution count falls.

**Demography (load-bearing wall):**
- Births 4.32M (2007) → ~3.59M (2023), ~17% decline (CDC/NCHS).
- HS grads peak ~3.9M/yr ~2025 (WICHE "Knocking at the College Door").
- Birth dearth hits college age 2029–2037.
- Northeast/Midwest/Plains lose 10–20% college-age; TX/FL/TN/GA/Carolinas grow (WICHE).
- Net domestic migration to Sun Belt (Census Bureau).

**AI's role:**
- Accelerant/sorter, not primary cause. Two-front squeeze: fewer 18-year-olds AND weakened degree signal.

**Signaling / demand:**
- Degrees lose signaling value asymmetrically by enforcement mechanism: licensed fields (state-gated) and super-selectives hold; mid-tier unlicensed BA premiums compress 30–50% real by mid-2030s. Sharpest in high-dynamism metros; mildest in state-gated fields.
- Fastest collapse in generalist white-collar fields (business, communications, generic liberal arts) where AI enables direct output verification; slowest where statute (nursing, law, accounting, teaching) or catastrophic failure cost (engineering, medicine) enforces the credential.
- Degree replaced as screening instrument, not positional good; by 2035 median degree = positional luxury marker ("completed a four-year gauntlet").
- Two brakes: AI application floods push employers back to crude degree filters; elite alumni-network/trust effects.
- Degree survives as insurance, not instruction: families buy selective degrees for sorting, licensure gatekeeping, alumni networks. Enrollment bifurcates by tier before region.
- Demand migrates to "protected degree + AI skill stack."
- Bimodal BA returns by mid-2030s (forecast, Unverified).
- Pre-AI employer drift away from degree requirements (Harvard Business School "Dismissed by Degrees"; Burning Glass Institute "The Emerging Degree Reset"; state degree-requirement drops).

**Program mix × region:**
- Licensed vs unlicensed share of credit hours = dominant predictor; region governs whether winning mix is reachable.
- Licensed expansion takes 7–10 years (clinical placements, faculty pipelines, state approvals) — longer than declining-region runway → decline locks in.
- SEC/Sunbelt publics +10–25% seats through ~2040 as legislatures fund as economic development.
- Northeast small privates without licensed core: −30–50% by 2040.
- "Program mix picks the winners, regional demography picks which losers can still switch."
- Three stacked currents: demographic cliff (NE/Midwest), migration to Sun Belt, AI disruption landing on white-collar task clusters in legacy NE/Rust Belt metros (finance, insurance, media, back-office) — highest sticker prices exactly there.
- Flagship brands everywhere partially insulated (Michigan, UVa, Wisconsin) — region AND stratum.

**Revenue shock:**
- Revenue event before headcount event; 2026–2032 mismatch window; seats priced above ~$15k net with no licensed anchor empty fastest; buyers defect.
- Anchors: BLS wage premium; Stanford Digital Economy Lab "Canaries in the Coal Mine" (2025) — early-career employment declines in AI-exposed occupations.
- Online-only/workforce providers ship in months vs 3–7 years through faculty governance/accreditation.

**Cost structure:**
- AI absorbs grading/tutoring/TA labor first; instructional savings capped at contingent labor layer (~20–30% of instructional spend, which is ~a quarter
