An inflation-linked security prices off a real curve, so its yield is a real yield, a return above inflation rather than in cash terms, and its principal is indexed. The figures below are in REAL terms unless labeled otherwise.

The index ratio is a multiplier, not a percentage: 1.2406 means the principal is worth that many times its original face today. So the real clean price of 99.969 is not what a buyer pays , multiply by the ratio to get 124.026 per 100 of original face.
Against the fitted real curve
Priced 3.67 cents per 100 of face cheap to the real curve on that day.
Shown as a price rather than a yield. Less than a month of this security's life remained, and annualizing a stub that short is arithmetic rather than information, the same reason its real yield is withheld above.

A CUSIP can be auctioned more than once: Treasury reopens an existing security rather than issuing a new one, so the same bond is sold again at whatever yield the market then wants.
Index levels before September 30, 2026 are back-tested. They were computed after the fact by applying the rules to historical data, which benefits from hindsight in the choice of rules, and an index cannot be invested in directly. Methodology v1.0 takes effect at that rebalance, when levels begin to be struck on the day; the rulebook is identical either way, and the version is published on every row.
A fitted curve is a fit, not a quote. Daily error averages 3.8 basis points across the history and reaches about 20 on the worst days, in December 2008, when the market was genuinely hard to fit one smooth curve to. Every curve page publishes its own fit error rather than burying it.
