Original question and givens
Use deterministic single-tape states=[q024, q124, qa24, qr24], input_alphabet=[024], tape_alphabet=[024, X24, _24], blank=_24, start=q024, accept=qa24, reject=qr24, transitions=[[q024, 024, q124, X24, R], [q024, _24, qr24, _24, S], [q124, _24, qa24, _24, L]]. Each transition is [state,read,next,write,L/R/S]; keys [state,read] are unique and halting states have no outgoing transitions. Input symbols form a blank-free tape subset. The integer-indexed tape is blank at every unlisted cell, with configuration [state,head,sparse nonblank tape]; L may move left of0. Canonical answer transitions/tape cells retain the source sort convention. Input=[024], step budget=2. Give (input, step_budget, configurations, step_outcomes, final_state, local_outcome, global_decider_certificate, boundary).

Conditions: none
All three lists are nonempty and unique;input is a blank-free tape subset,but state and alphabet labels may overlap.Source NUL-joined(from,read) keys are unique,and halting states have no outgoing rules.A partial table is legal,not filled with rejection;transition collation and UTF16 set order differ.
