The per-command sdmmc/sdspi DEBUG logs only existed to diagnose the CMD59 init failure, now resolved (verified 2026-07-11). Remove the build-time log ceiling and the runtime esp_log_level_set block.

# Rust often needs a bit of an extra main task stack size compared to C (the default is 3K)
|
||
# You might have to increase this further if you allocate large stack variables in the main task.
|
||
# Bumped for the TLS handshake (Spike 6): mbedtls runs on the calling task and
|
||
# wants several KB of stack on top of the app's own usage. 12 KB ran the editor
|
||
# AND a full TLS-on-main handshake on hardware — the last-known-good value for
|
||
# this shared stack.
|
||
#
|
||
# Spike 7 briefly bumped this to 96 KB because libgit2's push chain is far deeper
|
||
# (~67 KB measured for a trivial config write: nearly every function puts a 4 KB
|
||
# `char path[GIT_PATH_MAX]` on the stack and init→config→FATFS→wear-leveling
|
||
# nests ~10 deep). But this sdkconfig is SHARED with the editor build, so that
|
||
# forced the editor to over-reserve ~80 KB for nothing. Git now runs on its own
|
||
# large-stack thread instead (git_push.rs — GIT_STACK via
|
||
# std::thread::Builder::stack_size), so this drops back to the Spike-6 value.
|
||
# (The "time() only works on the main task" theory was a misdiagnosis: that
|
||
# iteration ran git on a std::thread with the DEFAULT 4 KB stack and just
|
||
# overflowed sooner — it was always stack depth, never thread-vs-main.)
