Dependency-curried candidate body; not Alpha-enrolled; no checked-use authority

Every position below an arbitrary finite chain length exposes its actual consecutive quotients and bounded base-p digit.

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.

Formal native tactic body

Dependencies are introduced as named hypotheses before line 1. Local theorem links identify exact declared prerequisites. This dependency-curried candidate body does not grant checked theorem use or Stable membership.
