Move debug diagnostics off /data/local/tmp/teesim to
/data/media/0/TEESimulator (visible at /sdcard/TEESimulator), so users
can pull them without a root explorer. The logging code runs in the
keystore SELinux domain, so a debug-only media_rw_data_file grant plus
a debug-only diag.sh fragment gate the plane: diag.sh's presence is the
signal service.sh (setup) and action.sh (export) test. customize.sh
extracts diag.sh on debug installs or sweeps the dir on release, since
the release keystore domain cannot remove it itself.
Replace the per-call .bin parcel dumps (a fresh undecodable file per
generateKey) with one NDJSON record per event on the UID's own file,
carrying decoded fields plus the raw parcel as base64 for the offline
parsers. computeIfAbsent makes per-UID writer creation atomic.
The piped getevent stream block-buffered on Magisk's BusyBox ash and
missed a single vol-key press before the timeout. Sample getevent in 1s
timeout bursts in a deadline loop instead.
Users reported vol+ confirmation not registering on Magisk. The
prior backgrounded `getevent -qlc 1` + `kill -0` poll captured
the first kernel event of any type, then restarted on miss. With
six events per keypress (EV_MSC scan, EV_KEY DOWN, EV_SYN, then
release variants) and a 1s poll cadence, the 10s budget exhausts
before a DOWN sample lands. The chainfire note that piped getevent
breaks BusyBox grep applies under Magisk's ash standalone mode.
Replace with a single streaming `getevent -lq` matched inline
against `KEY_VOLUMEUP DOWN` / `KEY_VOLUMEDOWN DOWN`, wrapped in
`/system/bin/timeout 10`. Full paths bypass BusyBox aliasing.
Add action_i18n.sh with 22 language arms (ar, az, bn, de, el, es-ES,
fa, fr, id, it, ja, ko, pl, pt-BR, ru, th, tl, tr, uk, vi, zh-CN,
zh-TW) plus an English default. Detect device locale via
persist.sys.locale with ro.product.locale and ro.system.locale
fallbacks; split Chinese on Hans/Hant.
action.sh sources the helper at top and substitutes every echoed
literal with $(_msg <key>). The confirm() flow stays unchanged.
Wire action_i18n.sh into customize.sh's per-file extraction list so
the helper lands alongside action.sh in /data/adb/modules/tricky_store
at install time.
Pattern mirrors tricky-addon-enhanced/install_i18n.sh.
Users reported accidentally triggering the module action button from
the root manager UI, which wiped /data/adb/tricky_store/persistent_keys
and forced every attestation-dependent app to re-enroll.
Gate the destructive operation behind an explicit Vol+ confirmation
with a 10-second timeout. Vol- or timeout aborts and preserves keys.
Pattern mirrors tricky-addon-enhanced/install_func.sh choose_automation
(getevent -qlc 1 polled per second), but defaults to cancel on timeout
because the destructive default of the previous script is the
behavior we are correcting.
Fork-based supervisor ensures the interceptor process survives crashes.
pingBinder() liveness check on pre-transact returns DEAD_OBJECT to
callers when interceptor is down, preventing real TEE state from leaking
during the restart window.
action.sh clears persistent key storage via KSU Action button.
uninstall.sh kills daemon processes and removes module artifacts while
preserving target.txt and keybox configuration.
