Connect DVP to Tiny DMA2/request 11, IRQ15 and the camera pad/reset lifecycle. Harden shared capture CDC, frame statistics, per-row size validation and HAL cleanup while preserving the Mini DMA3 binding and existing register ABI. Add deterministic capture/recovery firmware, source-bound evidence tooling, focused RTL/host tests and compact netlist acceptance. Preserve SAFE24, 128 KiB main SRAM, private Crypto storage and the locked dependencies. Retained validation: focused RTL, host/policy checks, Mini firmware, and ICS55/IHP130 RECOVERY, QVGA, synthesis and boot/DVP netlist checks pass. Full-system VGA remains historical; long full Icarus and broad regressions remain deferred. Global publication/format gaps and negative observational STA are retained, not reported as passing qualification. Specification: docs/ip/tiny-soc.md, TINY-R2-P9. Evidence: docs/ip/tiny-soc-verification.md.
