Updated the detailed design to match the shipped implementation: an as-built reconciliation table (P1-first, pinned-based DMA, D7 hard-cap-error, D8 output handle, prologue 1-stage-tile feed, D6.7 prologue-scoped), corrected file/test lists, the measured 5.22x dispatch ratio, and a new section 15 documenting the data-mode numeric subsystem (D8 + N1-N4) the original DDD omitted. Status Draft->Accepted; moved docs/adr-proposed -> docs/ddd/.
