Education
In-state tuition and fees at 4-year public institutions: IPEDS per-institution mean (2004+) spliced to NCES Digest Table 330.10 (pre-2004). No CPI fallback.
Sources
Precedence ladder for education. Lower precedence wins where multiple sources cover the same period. The engine walks the ladder per period with chain-link rescale at source transitions.
