Found the real cause of "-5: ipk verify failed": ares-package's own
packaging code (ar-async/fstream/tar, last touched 2017-2019) silently
zeroes every file's mtime in the ipk when run under a sufficiently new
Node (reproduced on v25.8.1; a Node-18 container was unaffected).
Confirmed by unpacking data.tar.gz from our built ipk (every entry
1970-01-01) versus webosbrew/hyperhdr-webos-loader's real published
ipk, structurally identical to ours (web app + native service, same
control file, same ares-cli) but with genuine October 2025 timestamps.
The archive still parses fine everywhere generic tooling looks —
Python's tarfile, our own ar/tar inspection — so nothing here ever
errors. The TV's own installer is what eventually rejects it, and it
gives no hint why.
This took three rounds of elimination to isolate: root elevation
wasn't it (Homebrew Channel's own root status was "ok"), and
system-wide native-code verification wasn't it either (a real
native-service app installed fine on the same TV). Comparing our ipk
against that known-good one byte-for-byte was what surfaced the
timestamp anomaly, and rebuilding under Node 18 reproduced correct
timestamps immediately.
build.sh now runs ares-package inside a pinned node:18 container by
default, falling back to the host's Node with a warning if Docker
isn't available. Rebuilt the actual release ipk this way and
regenerated manifest.json/repo.json against its corrected hash.

The openlgtv NDK is a Linux toolchain with no macOS or Windows build, so
tools/build.sh could not produce a binary anywhere else. docker-build.sh
bakes the SDK into an image and compiles there; packaging and deploy stay
on the host, where the TV is reachable. The SDK ships aarch64 as well as
x86_64, so the image picks the one matching the daemon and Apple Silicon
builds natively rather than under emulation.
Cross-compiling for real turned up three things the host compiler did
not:
sink_hyperhdr_viz.c read p->width and p->height to format the error
message after free(p)
sink_hyperhdr.c an SDP connection line of 128 bytes cannot hold
"IN IP4 " plus a 127-byte host plus "/255", so a
long hostname would silently lose its TTL suffix
common/log.c the log body was sized to the whole ring line,
leaving nothing for the prefix; budget for it so
the bound is provable rather than left to
snprintf
A clean cross-compile is now warning-free, and readelf confirms the
design rule holds: luna-service2, glib, PmLogLib and libc, with no
libpulse or libasound.
Also: @webosose/ares-cli was pinned to ^3.0.0, which does not exist
(latest is 2.4.0), so npm install failed outright. build.sh now puts
node_modules/.bin on PATH so a local install is enough.

Captures the TV's audio and sends it out over several transports. The
primary one is HyperHDR: RTP/L16 to a host-side loopback device, since
HyperHDR has no network audio input of its own. A second route renders
the spectrum on the TV and sends FlatBuffers images to port 19400
instead, for setups where touching the host's sound config is not an
option.
native/ the service: capture backends (PulseAudio, ALSA, exec,
test tone, all dlopen-based), DSP, and one file per sink
frontend/ D-pad driven UI at a fixed 1920x1080
servicefiles/ native service manifest plus the boot script
host/ RTP receiver and the loopback installer for the HyperHDR
machine
tools/ build/package, asset generation, Homebrew Channel
manifest, on-TV probe
test/ host-side suites: FlatBuffers and RTP verified against
real decoders, the engine end to end, the page in jsdom
