+# fp6-vendor-blobs-extract - copy proprietary blobs out of the stock Android
+# partitions instead of distributing them. pmOS installs flash only
+# boot+userdata, so every installed FP6 still carries the stock vendor/dsp
+# partitions: the device duplicates files it already contains, for its own
+# operation - nothing is distributed by us or anyone else. Design, legal
+# frame and on-phone verification: fp6 repo journal/blobs/.
+#
+# Manifest fragments: /usr/share/fp6-vendor-blobs/manifest.d/*.manifest,
+# processed in sorted order; '#' comments and blank lines ignored:
+#
+#   file <partition[,partition...]> <path-in-partition> <dest> <sha256>
+#   rebind <bus> <device>
+#
+# file: mount the first available listed partition READ-ONLY (ext4 also
+#   gets -o noload - never a byte written to the stock partitions, not
+#   even a journal replay), copy <path-in-partition> to <dest>, verify the
+#   sha256. A missing source or a hash mismatch tries the next listed
+#   partition; no verified copy on any of them fails the run loudly - an
+#   unverified blob is never installed and a missing one never silently
+#   skipped. Dests that already exist are left alone (no hashing: a
+#   deliberately replaced file stays).
+# rebind: if this fragment's run extracted at least one file, unbind and
+#   re-probe <device> on <bus> so the consuming driver picks the file up
+#   in the same boot. Unconditional on purpose: a still-bound consumer may
+#   have already failed a deferred firmware request that is never retried
+#   (aw88261 binds on i2c probe but requests the ACF only at card init),
+#   so only a fresh probe with the file present is a known-good state.
+#   All of a fragment's devices are unbound first, then re-probed, so a
+#   shared sound card re-forms once instead of bouncing per device.
+#
+# Partitions resolve via /dev/mapper (the pmOS initramfs maps the dynamic
+# partitions in super on every boot), then /dev/disk/by-partlabel (raw
+# partitions like dsp_a), then one make-dynpart-mappings fallback run;
+# mappings that run creates are removed again at the end.
+#
+# --if-device: exit 0 quietly when no stock super partition is visible
+#   (apk post-install scripts run inside build/CI chroots too; on images
+#   built there the first-boot service does the real extraction).
