Findings to Prioritize

• old override syntax in a modern layer without a release reason
• missing or vague LICENSE and LIC_FILES_CHKSUM
• ${AUTOREV} in production metadata
• missing DEPENDS for headers, libraries, generated code tools, or -native tools
• runtime dependency added to DEPENDS instead of RDEPENDS:<package>
• installed files not covered by FILES:*
• installing outside ${D}
• host path or host tool contamination
• unnecessary INSANE_SKIP
• patch entries with missing upstream status or fuzz
• bbappend that is too version-specific or too broad for the intended target

Modern Syntax

Prefer:

FILES:${PN} += "${bindir}/tool"
RDEPENDS:${PN} += "bash"
PACKAGECONFIG:append = " feature"
do_install:append() {
    install -d ${D}${bindir}
}

Avoid _append, _prepend, _remove, and old package override syntax unless the target release requires it.
