* ci: watch for drift from firmware instead of finding it by accident builder.sh copies devices/<item>/* over a fresh firmware clone, so a device directory that ships its own copy of a firmware file replaces it outright. A fleet-wide change in firmware reaches every device that only references a path and none that ships its own copy, silently, because nothing in either repository is looking. One comment on OpenIPC/firmware#2308 turned up three instances of that in an afternoon: 13 board configs that missed the CONFIG_VT sweep (#126), 97 defconfigs that kept BR2_PACKAGE_JSONFILTER after firmware retired it and put three devices over their rootfs cap (#128), and excludes lists naming files that no longer exist (firmware#2313 reports those at build time). The trigger is the design. Every one of those was caused by a commit in firmware while this repository sat untouched, so a pull_request check would never have fired for any of them -- nobody opens a builder PR when firmware changes. firmware-drift.yml runs on a schedule and files an issue rather than failing: drift someone else introduced is not a reason to redden a nightly that is otherwise fine. Only the self-test gates a merge here, out of lint.yml. Two checks, because the two kinds of drift are not the same shape. Shadowed files: comparing content is useless, a builder copy is *supposed* to differ. What matters is whether firmware's version moved since a human last reconciled them, so each of the 13 entries pins the blob it was reconciled against. Re-pinning is the act of looking again. The mapping is hand-authored -- nothing can infer that gk7205v200.generic-fpv derives from gk7205v200.generic. Defconfig symbols: nothing here copies a firmware defconfig, so pinning does not apply. Every BR2_PACKAGE_*=y is resolved against buildroot, firmware and this tree and sorted into "resolves nowhere" (a dead line kconfig ignores) and "resolves, but no firmware defconfig selects it" (needs an allowlist entry). An allowlist entry can also fence a symbol to the devices that need it; without that, writing JSONFILTER down as builder-only for devices/apfpv would equally bless it creeping back onto 95 unrelated defconfigs, which is #128 verbatim. Replayed against the three regressions, each reproduced by hand on a clean tree: firmware moves a shadowed config -> br-ext-chip-goke/board/gk7205v200/gk7205v200.generic.config moved in firmware since this copy was reconciled (2026-08-25). builder copy: devices/common/.../gk7205v200.generic-fpv.config pinned 7450c6803f6d, firmware now f97dce84c0f8 firmware commits since: 85233f0e kernel: drop CONFIG_VT and the busybox applets ... (#2308) jsonfilter creeps back onto a non-apfpv device -> BR2_PACKAGE_JSONFILTER is allowlisted only for apfpv/*/configs/*_defconfig, but 1 other defconfig(s) select it. firmware retires a symbol builder still selects -> BR2_PACKAGE_LIBUBOX is selected here but by no firmware defconfig. Resolving against buildroot is not optional and getting it wrong is how a checker lies. Buildroot is vendored by neither repository, so a first pass over OpenIPC packages alone called HOSTAPD, IW, PHP, UHTTPD, LIBZIP and BWM_NG dead; all six are upstream. Matching only "Config.in" then called PHP_EXT_ZIP dead, because buildroot declares php's extensions in package/php/Config.ext. Without --buildroot that half is skipped and says so rather than inventing findings. Two symbols really do resolve nowhere today -- BR2_PACKAGE_APFPV_GREG on the four greg-generic devices and BR2_PACKAGE_WIFIBROADCAST_EXT in devices/common. Both are recorded as known-dead and reported as a notice on every run rather than removed: whether those devices still want the packages is a maintainer's call, not a side effect of adding a check. The three new paths are classified in ci-matrix.py so this PR and every future re-pin cost no device builds. Without that a blob update is a 107-device run. * ci: discover shadowed files instead of listing them by hand Qodo caught the shadow list omitting the device-local t21 and t31 kernel configs. It was right, and the hole was much bigger than the five it named: a hand-written list of 13 board configs against 93 same-path shadows covering 35 firmware paths. The missing ones are not incidental -- load_goke, load_hisilicon, load_sigmastar and four vendor .mk files are all shadowed by some device, and those are exactly the shared files a fleet-wide fix lands in. firmware regression-tests load_hisilicon's os_mem_size derivation; two devices here ship their own copy of that script and would not have seen the fix. Listing them by hand was the wrong shape. builder.sh copies devices/<item>/* over the firmware clone, so any file at a path firmware also has replaces it -- which makes same-path shadows discoverable rather than something to remember. discover_shadows() walks devices/ and reports anything sitting on a firmware path with no entry in firmware-drift.json, so the list cannot silently rot and a device added tomorrow cannot quietly introduce an unreconciled shadow. The manifest goes from 13 entries to 101: the 88 discovered ones, plus the 13 hand-authored entries that discovery cannot find because the name differs from the file they replace -- gk7205v200.generic-fpv shadows gk7205v200.generic, and nothing can infer that. Two self-test cases for the new path: a same-path shadow with no entry is reported, and an entry silences it. Verified against the tree by dropping the load_hisilicon entries, which surfaces both devices immediately.
