mirror_displays() now checks CGDisplayMirrorsDisplay() for each secondary
before calling CGBeginDisplayConfiguration — avoids a needless display
reconfiguration (and potential flicker) when already mirrored.
extend_displays() already had this check; no change needed there.
scp's own user@host:path parser splits on the space in 'speaker ready'
even when the shell argument is quoted. ssh already handles it correctly.
Upload: ssh cat < file; Download: ssh cat > file.
Copies display_control.m to laptop 01 via SSH, compiles universal binary
(x86_64 + arm64) on the remote Mac, pulls binary back to resources/bin/.
Defaults to 192.168.32.101; accepts optional IP override as $1.
README: restructure display_control build section — Option A (remote from
workstation, preferred) and Option B (direct on Mac).
Compiles both arches separately then links with lipo -create.
Prevents silent failure when a binary built on Apple Silicon is deployed
to Intel venue Macs (MacBook Air 2018 fleet).
Derived from OSIT MasterKey app (LegacyUtilities.m, Ian Kohl 2019).
Uses CGConfigureDisplayMirrorOfDisplay — native macOS API, no Homebrew dependency.
Handler now tries display_control first; falls back to displayplacer for missing binary
or per-device configStr overrides. Build the binary via scripts/build-display-control.sh
on a Mac (requires Xcode CLT only), then commit resources/bin/display_control.

Packaging was silently hanging forever because yauzl 2.10.0 read streams
emit no data events under Node 26, causing extract-zip to block indefinitely
inside @electron/packager 20. Fix: postinstall script patches
@electron/packager/dist/unzip.js to use bsdtar (libarchive) instead.
bsdtar was chosen over 7z because 7z refuses chained symlinks in macOS
.app framework bundles. Both package:linux and package:mac now produce
correct output.
Also corrects the V3 API bootstrap contract in api_client.ts:
- SearchQuery body was wrapped in an extra {search_query: ...} layer — removed
- x-no-account-id header standardised to 'bypass'
- Redundant x-no-account-id removed from file download headers
- Smoke test rewritten to validate the real two-step bootstrap path
