The capture half -- dump_packages, pull_apks, pull_sdcard, dump_settings
and dump_focus_state -- moves into lib/backup_capture.sh. SDCARD_DIRS goes
with pull_sdcard, its only reader: left behind it would be a global the
entry script never reads (SC2034), and the hook runs shellcheck without -x
so each file has to stand alone.
This code decides what a phone backup actually contains and had no test at
all. It has one now, against a fake device mocking adb_cmd -- the single
boundary all five functions cross. 22 assertions, 52/52 lines, and 13
mutations all killed. One of those mutations reintroduces the stdin-
draining bug pull_apks' own comment documents (it pulled 1 of 54 packages
before it was fixed); the suite catches it.
Nine of the ten functions moved verbatim per verify_shell_split.sh.
dump_focus_state is the exception and the tool correctly says so: its
`{ ... } >file` group hid a line kcov instruments but bash never reports,
and rewriting it as individual redirects drew SC2129 instead. One printf
satisfies both. Its rendered focus-state.md was diffed against HEAD's
output on the same inputs -- byte-identical.
Same for three multi-line literals (SDCARD_DIRS and two mapfile process
substitutions), which were stuck at 1/N covered for the same reason.
phone_backup.sh is PC-side and in neither deploy list, so no list edits.
--help exits 0; --verify on an empty dir exits 1 naming the four missing
files, matching HEAD exactly. Over-cap count 22 -> 21.
