Database only; no application code changed, so the served path, champion
and reference ruler are byte-identical.
RESULT: 862 rows re-stamped from the takeable LOCK-TIME price in
lock_lines, 862/862 now anchored to takeable books, tagged
price_source='archive_restamp', quarantine lifted. 812 pending clean rows
recovered into the accruing verdicts. Holdout verification: 2,792 rows,
862 re-stamped included, 0 re-stamped rows non-takeable, 144 still
excluded, 0 quarantined rows leaked, and 0 NON-TAKEABLE rows remain in the
holdout population since 2026-08-01.
DEVIATION, stated rather than buried: the order authorised 936. That
figure came from a takeable book posting the same LINE. Requiring what a
re-stamp actually needs -- that book's price for the GRADED SIDE at LOCK
TIME -- resolves 862. Of the other 74, 73 have a takeable side-price only
OUTSIDE the lock window and 5 are genuinely one-sided markets.
I did not widen the window to reach 936. A takeable price captured hours
after the grade is a later market moment, not a lock price; substituting it
is precisely the reconstruct-vs-join line this order was fenced against,
and it would have been invisible in the totals -- showing only as a
cleaner-looking 936.
Those 74 were also RE-TAGGED, because their old label had become a lie:
recoverable_same_line -> no_takeable_lock_price_for_side. A future attempt
reading the old tag would have been invited to widen the window and call it
recovery.
takeable was RECOMPUTED from the recovered price rather than carried over
-- the old flag was computed FROM the contaminated price and was wrong on
its own terms. 101 rows had their flag change, which is the direct measure
of how wrong it was.
Provenance travels with the data (price_source), on the same principle as
is_proxy: a value recovered by a later join is not identical in kind to one
captured natively at grade time, even when it is the same number.
EVIDENCE FOR THE NEXT ORDER'S INVARIANT: 5 of the excluded rows are
one-sided TAKEABLE markets, and betrivers/hardrockbet legitimately quote
one side only. A guard that inferred takeability from price shape would
throw away real markets while still admitting a DFS book at -119 --
takeability is book IDENTITY, never price extremity or one-sidedness.
