Treasury auction concession — no-return feasibility protocol
Scope
This stage reads only official US Treasury auction metadata. It does not load prices, calculate returns, select an entry window, or spend a return identity. The objective is to establish that the coupon-auction event clock can be reconstructed from fields knowable before each auction.
Source and immutable lineage
- Source: Treasury Fiscal Data
auctions_queryAPI. - Start date: 2000-01-01.
- Eligible security types: nominal
NoteandBondonly. Bills, TIPS and FRNs are excluded. - Raw response is canonicalized, SHA-256 hashed and atomically stored.
- Event identity is
auction_date|CUSIP; duplicates fail the gate. - The emitted Parquet contains announcement-safe fields only. Auction outcomes such as high yield, allocations and bid-to-cover are deliberately excluded from the event manifest.
Gates locked before execution
- At least 1,000 eligible coupon auctions.
- At least 500 auctions from 2013 onward, preserving a publication-aware falsification era.
- At least 99% completeness for identity, announcement, auction, issue, term, amount and reopening fields.
- Announcement date is never after auction date for at least 99% of rows.
- At least one calendar day of notice for at least 99% of rows.
- Event identities are unique.
Passing these gates authorizes a separate return preregistration. It does not authorize a return test by itself. The return specification must lock duration buckets, beta hedges, event windows, transaction costs, post-publication priority and overlap handling before opening prices.
Kill conditions carried forward
Kill if the effect is absent after publication, reduces to duration beta, fails one-tick-plus-fee cost stress, or exceeds 0.35 correlation with AlphaTrend. The sign and window will not be inverted or retuned after a failed locked identity.
