Current library: Alpha v34, 4,223 checked-use theorems; Stable remains 432. Historical first admissions, original proof editions, and non-admitted aliases are preserved. Exact original first-admission records.
Exact expanded first-order arithmetic statement
forall m d q t p. (exists w. q + d * t = p * w) -> exists w. m * q + (m * t) * d = (p * m) * wConstructive proof overview
Generated structural guide
A root-correction divisibility witness makes the complete first-order lifted value a multiple of the next modulus.
The unchanged tactic script uses 3 declared prerequisites and contains 27 exact native proof lines.

Formal native tactic body
Dependencies are introduced as named hypotheses before line 1. Local theorem links identify exact declared prerequisites. This exact body belongs to a complete independently kernel-checked constructive proof bundle and has Alpha checked-use authority; it does not imply Stable membership.
