Preserve the Ch441 timing/renderer board-validation evidence and the Codex-directed follow-up: - FB reconciliation: the Ch437 A/B dump's 8-word first-beat delta was a non-reproducible one-time transient; 3x render+dump and 8x pure-probe re-reads all return golden d0047677 (words 0-7 correct). Memory integrity confirmed deterministic. (fb_reconciliation.md) - Structural audit + A-D diagnostic proposal for LPDDR_STATUS[5]: bit5 ORs sticky CDC-synced underflow with AXI read-errors; dump path (arid=1) is separate from scanout/HDMI (arid=3). Instrumentation proposal only, not implemented. (scanout_status_bit5_proposal.md) - Raw board logs, status samples, RBF hashes, A/B FB dump, board PNG. No RTL edits, no compile, no builds.
