Summary

  • reify the planner-returned final program into the emitted theorem
  • seed caller facts by exact base-list position through generic assumedAt
  • seed instantiated nodes from exact program lookups and domain-top soundness
  • remove all named sine-specific previous-fact constants from the tactic path
  • reject a final program that omits the instance event's generated nodes

Evidence

The fully printed tacticSine term contains seedAssumed and topFact; it contains none of sineBase, negatedBase, sinePrevious, negationPrevious, or transportPrevious. The diagnostic print was removed after inspection.

Verification

  • lake build HexIntervalMathlib.SineTacticConformance (1,956 targets)
  • copyright, line-count, DAG, and diff checks
  • changed Lean contains no native_decide, axiom, or sorry

Stack

Depends on #9204. The stack will be reconciled with repaired #9201 before merge.
