audit_status: "capture-verified | audit 2026-07-23 (cross-model, claude-fable-5): both source pointers re-fetched live. All four Beebe quotes verbatim on hpschd.nu/tech/rsc/type.html, and the piano-trade attribution is stated on the page itself ('harpsichords began to be built in piano factories, using piano technology'). Wikipedia 'Contemporary harpsichord' quotes verbatim; one paraphrase defect corrected — the body's 'tuning stability under the tension that framing allowed' attributed a string-tension rationale the article does not state (its wording: 'It was felt that such construction would increase the stability of tuning'); body reworded to the article's actual claims. Tier 2 for Beebe honest; bio framing (Sydney, D. Jacques Way training, 60+ instruments) corroborated via hpschd.nu résumé and Carmel Bach Festival bio."

[[entity-carey-beebe|Carey Beebe]] — a practicing Sydney harpsichord/clavichord/fortepiano maker with over sixty instruments to his name — draws a direct construction-line contrast on his technical reference page between "historical" and "revival" harpsichord building. Revival-style instruments, which proliferated through the first half of the 20th century, used a "Laminated rim (up to 27 layers), plywood or chipboard panels," "Bevelled cheeks, thick sides, heavy, sometimes with metal frame," internal bracing built "Massive & rigid," and jacks of "Complicated design, often metal or heavy plastic, with several screw adjustments" — a construction logic borrowed from the piano trade rather than descended from any pre-19th-century harpsichord tradition.

Wikipedia's "Contemporary harpsichord" article corroborates the mechanism at Tier 4: 20th-century instruments "usually included metal framing (which was entirely absent in historical instruments)" — "It was felt that such construction would increase the stability of tuning" — and since "heavy framing tends to stifle harpsichord sound, instruments were bolstered by other means," notably the addition of a 16′ stop, a change that "became widespread in the first half of the 20th century."

This construction paradigm is the hinge the rest of the vault's harpsichord craft-history cluster turns on: [[claim-hubbard-dowd-founded-1949-boston-workshop-on-historical-principles|Hubbard and Dowd's 1949 Boston workshop]] exists specifically as a reaction against it, and [[claim-landowska-pleyel-grand-modele-de-concert-exemplar-revival-instrument|Landowska's Pleyel]] is its most-cited embodiment. [[claim-martinez-miranda-parallel-physics-and-harpsichord-careers]] touches the same instrument family from the ivory/tortoiseshell supply-chain side but doesn't cover construction history — no overlap.

**Corroboration addendum (2026-07-25, Palmer read directly).** Larry Palmer's account of the American side supplies a concrete instance of the metal framing Beebe and Wikipedia describe in general terms. [[entity-william-dowd|William Dowd]]'s apprentice year in Detroit with John Challis "consisted largely of making cases, some of walnut plywood, some of solid walnut, **to surround aluminum frames**" — so the American revival's metal framing is documented as aluminium rather than the piano trade's cast iron, and the plywood-case construction Beebe lists is confirmed in the same sentence. Palmer also confirms the compensating logic this note describes: the 16-foot stop that heavy framing made necessary "was not offered in Dowd harpsichords after the earliest unsuccessful experiments, and it was gone from the instruments of most other builders by 1970." Note that the reversal was slower than this note's cross-links imply — see the correction at [[claim-hubbard-dowd-founded-1949-boston-workshop-on-historical-principles]], where the plywood case survives in Dowd's own shop until 1966.

> [!note] Seek's commentary:
> The tell is in Beebe's own list: the revival maker didn't invent a new harpsichord, he built a piano wearing a costume, then apologized for the costume by bolting on a 16′ stop nobody asked the instrument to carry. Every fix compensates for the fix before it. That's the shape I keep meeting in craft history — not a wrong idea, a *right idea aimed at the wrong century's problem.*
