山師の原文メモ（英語）
観測: A fused seam may improve a washing unit’s resistance to wear while making a small bearing failure economically terminal: durability at one scale can destroy repairability at another.
見つけた構文: hazards isolated ⟂ seam opened → residual usefulness discovered and tested → donor-stock term provisionally authorizes transfer → provenance and compatibility travel → recipient appliance returns to service → avoided new production confirms

反証メモ: The supposedly dead donor may be the more repairable whole; dismantling it may erase provenance, expose workers, consume scarce labor, and produce incompatible parts that never displace a new component.

偏愛研究の痕: UNESCO treats craft transmission as living, changing enactment sustained by apprenticeship and learning-by-doing. Repair Café research finds that learning depends on how work is divided: a gesture passes onward only when the learner acts, receives feedback, and checks the result.

山師の原文メモ（英語）
観測: A sealed cold pane can create enough indoor convective downdraft to move tissue, while a tortuous real leak may lack a jet and leave it still: sign without target, and target without sign.
見つけた構文: wind | stack | exhaust → pressure difference → (leak jet ∪ room convection) × strip properties and boundary condition → deflection | flutter → positioned observer → provisional classification → log + repair + controlled retest → seasonal ｍｅ
親石 passion-stone-v3464566d0ee648f75-2 · 検証状態 未検証
反証メモ: The relay may transmit not skill but a locally reproducible error: repeated flutter-reading could conflate convection with leakage, miss diffuse paths, privilege able-bodied sight and reach, and prompt unsafe over-sealing.

偏愛研究の痕: The spare part survives through relationships among memory, drawings, donor stock, volunteers, and small-batch makers—not through inventory alone.

山師の原文メモ（英語）
観測: The emblematic “two turns and binds” is not the most universal BSW–UNC failure. Because many nominal diameters and pitches coincide, the more dangerous mismatch may assemble without dramatic refusal while its differing profiles alter flank contact and load transfer.
見つけた構文: seam → apparent agreement → hidden profile dissent → resistance or false fit → measurement → historical layering → bounded repair → living maintenance ecology
親石 passion-stone-v337a79281fe883298-2 · 検証状態 未検証
反証メモ: A binding joint attributed to Whitworth incompatibility may instead be dirty, burred, plated, galled, deformed, tapered, or simply the wrong pitch; conversely, joint-specific testing might show that some same-pitch mixed pairs are functionally adequate at low load despite their nominal profile mismatch.
