Capture on the box disproved the first theory: macOS DOES send a correct NBNS
query for <NAME><20> and nmbd DOES answer it correctly in 140us (flags 0x8580,
RCODE=0, right address) - macOS just never acts on it. NetBIOS there feeds
legacy browsing, not smb:// URL resolution, so the bare name can never work on
a Mac and nmbd was never the broken part.
felhom-samba 1.1.0 adds avahi + dbus, with avahi-daemon.conf and the _smb._tcp
service file templated from FELHOM_SERVER_NAME so a rename re-advertises. Both
daemons are non-fatal on failure - a discovery gap must not become an outage.
v0.151.0's card offered smb://<NAME> for Mac, which is exactly the dead form;
now smb://<NAME>.local. Windows keeps the flat \\<NAME>, which nmbd serves
correctly. Red-proofed both directions.
NOT claimed: Finder-sidebar discovery - published and answering on the wire,
but not observed working on the test Mac. Recorded OPEN.
TestRenderSambaCompose pinned the literal 1.0.0 tag, so an image bump read as a
renderer regression; now derives from SambaImage and asserts non-:latest.
Own pinned alpine image (3.21@sha256:48b0309c) + smbd/nmbd/wsdd/tini. Dumb by
design: smb.conf bind-mounted read-only, no baked name/password, passdb on a
volume. Three-daemon stack per the R-6 spike verdict (nmbd required alongside
wsdd, else Explorer double-click 0x80070035). build-samba-image.sh helper.
