v2 (April 2026): Reference list refined per paper. External references corrected and finalized; no self-citations. v1 (DOI 10.5281/zenodo.19837588) remains the original publication. English: A hypothesis-driven research programme on black hole thermodynamics from two conditional propositions: (Hypothesis 1) black holes are projected images of higher-dimensional structures; (Hypothesis 2) Hawking evaporation is the drift of discrete units across boundaries. This first paper situates the programme within existing literature, articulates the hypotheses precisely, previews the verification structure across five companion papers, and addresses anticipated critiques. Does not derive thermodynamics; defines a research programme. 日本語: ブラックホール熱力学への仮説駆動型研究プログラム。仮説1:BHは高次元構造の射影像;仮説2:Hawking 蒸発は離散単位の境界ドリフト。本第一論文は文献内位置づけ、2仮説の精密表明、5姉妹論文での検証構造の予告、予期される批判への応答を扱う。熱力学を導出せず、研究プログラムを定義する。
