Build a source-first Hugo retrospective covering the Tesla Cybertruck from the November 2019 reveal through July 24, 2026. Scope: promise ledger, chronology, market/sales evidence, NHTSA recall record, historical-comparison methodology, source register, accessibility, local tests, GitLab Pages configuration, and autonomous Senate advisory review before go-live. Editorial posture: proven volume under-delivery; plausible high-recall/depreciation case; a completed Edsel/DeLorean-class historic-flop verdict remains premature.
