Replace every em dash with real punctuation (rewrites, not hyphen swaps)
in docs, code comments, scripts, configs, and the port records; convert
en dashes, curly quotes, ellipsis glyphs, arrows, and section signs to
ASCII; drop machine-writing tell phrases from living docs. ADR titles
now use a colon. The M2 bring-up DTS model string carried an em dash
into the patch series and its record echoes; fixed at both, and the full
series re-verified to apply cleanly onto pristine 6.18.46. One comment
in freshness.h deliberately names the em dash glyph the UI renders as
the unknown mark; that is data, kept as prose naming it.
Verified: cargo tests (sim, config-lint, rs485-bridge), shellcheck,
both driver MC/DC harnesses, patches-apply.
Preparing the repo to go public (ADR-0007):
- CI: kernel-build moves from the self-hosted runner to ubuntu-latest
(installs its own cross toolchain + qemu, caches the pristine tarball).
On a public repo a registered self-hosted runner is reachable from
approved fork-PR workflows — i.e. arbitrary code on private
infrastructure — and the build never actually needed the SDK host.
ADR-0004 marked superseded-in-part; docs/ci-cd.md rewritten (site
specifics now live only in the private deployment log).
- Licensing: LICENSE gains the GPL-2.0 carve-out for patches/ and the
kernel source excerpts (Linux derivatives; per-driver provenance was
already tracked in PROVENANCE.md); patches/README.md states it too.
- Scrubbed from the tip: bench-unit dev credentials and its gadget IP
(m2-boot notes), the site AP SSID+BSSID and a neighboring AP's BSSID
and the device WLAN MAC (wifi bring-up evidence — BSSIDs are
geolocatable), the runner mesh IP. NOTE: these remain in git history;
decision on a pre-publication history rewrite is separate.
- Emoji cleanup across 21 tracked files (kernel port docs, review report,
enforce-mcdc.sh) per repo text conventions: status marks became
[x]/[wip]/[ ]/OK plain text.
- "[maintainer]-gated" process phrasing normalized to "maintainer-gated"
(attributions in dated evidence docs kept).
Verified: zero emojis tracked; scrub grep clean; patches carry no internal
references; ci.yml parses; shellcheck unchanged.

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.
