mailbox + NPU + pvtm all now show VERIFIED with accurate notes (the prior
reason cells still said 'unexercised'/'no userspace'/'deferred'). Only
crypto-accel (CPU crypto covers) and open-NPU-compute (person-year RE) remain,
both documented.

MAILBOX (fully open A7<->RISC-V SCR1 round-trip, 5/5 exact echoes on c8a3):
- rockchip-mailbox.c: rv1106 has 1 shared IRQ, not 4/channel -> added
rv1106_drv_data{num_chans=1} + compatible (rk3368 fallback assumed 4 -> probe
failed 'IRQ index 1 not found').
- clk-rv1106.c: CLK_CORE_MCU (SCR1 core clock) marked CLK_IGNORE_UNUSED -
6.18's clk_disable_unused() was switching off the coprocessor clock so a
loaded firmware never ran (5.10 left it on).
- Open SCR1 echo firmware (scr1-echo/, 154B RV32IMC) + load/test scripts;
A2B_INTEN on the MCU side + CMD-then-DAT (DAT=doorbell) order. Loaded via the
proven hpmcu.rs SRAM path; do NOT kill warden-flared (dw-wdt). mailbox/VERIFIED.md.
NPU (open GPL rknpu 0.9.2 kernel driver on 6.18):
- DT fix: base npu node lacks interrupt-names, driver requests IRQ byname
'npu_irq' -> probe bailed -ENXIO. Added interrupt-names='npu_irq'.
- Verified: [drm] Initialized rknpu 0.9.2 on minor 1; /dev/dri/card1;
rknpu_version_test PASS (0.9.2 + hw version, full power/clock/reset path).
- Honest ceiling: open compute (regcmd compiler) is a from-scratch ~person-year
RE project, no RV1106 prior art; ship the driver, no blob. npu/VERIFIED.md.
DRIVER-PARITY + CAPABILITIES-AUDIT updated; dts snapshot refreshed.

Six drivers verified on hardware this run (wifi, TRNG, OTP, GMAC, SARADC,
audio). Final honest ledger: mailbox (fallback-binds, no client), crypto-v3
(CPU crypto covers), NPU (no open userspace), pvtm (DVFS-only) all deferred
with reasons — no unexplored capability gap. Morning bench tasks documented
(display connector, audible audio, wifi boot-time auto-load).
OVERNIGHT-RESULTS.md added.

Capabilities audit — classify every RV1106 SoC block against a 6.18 driver:
GMAC (wired eth, enabled on-board), crypto-v3, trngv1 (hw RNG), OTP, mailbox,
NPU, audio codec/DSM, pvtm still to port; camera/ISP + SPI are N/A (no HW).
Provenance ledger — per [maintainer]'s openness directive extended to already-ported
drivers: every ported driver is GPL-2.0 kernel source (vendor-src or
mainline-sibling); the only binary in the whole path is on-device wifi-chip
firmware, which by construction cannot be host source. No vendor binary is
loaded into our kernel.
