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.
The repo's documentation framed it as a support repo for one product
(WardenOS). Since going public the real audience is anyone with a Luckfox
Pico 86 Panel: a maintained 6.18 kernel, an off-device development loop,
and a device simulator that exist nowhere else for this board. Reframe the
README and top-level docs board-first, with WardenOS documented as the
downstream consumer it is (ADR-0008).
Also an editorial pass over the whole doc set:
- every H1/H2 is now a short title, not a sentence (ADRs, qemu/, patches/,
drivers/, architecture, NPU feasibility, config-lint, payload); workflow
flowchart titles fixed at the source in tools/flowgen.py and regenerated
with fresh bench numbers
- README Quick Start commands verified against the scripts; requirements
corrected (curl, bare python, gcc >= 14) and the MC/DC gate added as a
step (run green locally on gcc 14.2)
- dropped the 'needs python (not python3)' vendor dig: build-kernel.sh
inherited the same requirement (filed #10 to remove it)
- glossed MC/DC and HPMCU on first use; marked the tests/uboot-ab
reference as flare-edge; deduplicated the three-simulator list into the
root README table
Phase 4+5 of the device sim:
- Display + touch verified end-to-end: virtio-gpu at 720x720 (fbdev
emulation) renders the real WardenOS dashboard from the static LVGL
fbdev+evdev UI build (flare-edge qemu-vm-support tools/build-ui-vm.sh);
QMP input-send-event taps the Metrics tab and qemu/tests/ui-shot.sh
asserts the repaint from screendumps. Two load-bearing QEMU flags found
and documented: -global virtio-mmio.force-legacy=false (gpu/input are
VERSION_1-only) and the 200ms press hold (an instantaneous press+release
lands inside one LVGL indev poll and never clicks).
- qemu/tests/qmp.py: minimal QMP client (screendump, tap, quit).
- stage-2 init starts warden-ui when present and fb0 exists.
- docs/decisions/0006-qemu-device-sim.md: virt-not-custom-board, the
enters-at-kernel boundary, fragment policy, naming, consequences.
- docs/architecture.md: new section 7 (device emulation), order-of-work
item 7; modbus cross-reference to the bridge.
- qemu/README.md: emulated-vs-not table, scenarios, gotchas, host/runner
requirements. docs/ci-cd.md: runner needs one-time qemu-system-arm
install (fail-closed smoke until then, [maintainer]-gated). Repo README updated.
Final sweep on this commit: shellcheck clean, bridge 7/7 tests, boot smoke
PASS, portal scenario PASS (check-in + fw pull + signed .wfw download),
ui-shot PASS (touch navigates to Metrics) — all under the final flags.
