CI Benchmark - Fusion Loop Timing / Fusion Loop Timing Benchmark (push) Waiting to run
The per-test setjmp/longjmp recovery loop in test_runner.c (main()) was
already delivered by sibling bead bf-bq9 (commit 549dc1f) and verified to
satisfy bf-53ut's contract: a failing assertion longjmps back to main()'s
setjmp, which falls through to advance the loop, so a failure in test N
never blocks tests N+1..end (proven with a temp failing-test followed by a
passing test — both ran and the process completed without aborting).
This commit lands the three harness files that were staged but absent from
HEAD (Makefile, .gitignore, test_sanity.c) so that 'make -C firmware/test
test' — the command bf-53ut's acceptance invokes — actually builds and runs
against the committed tree. Without them the committed test_runner.c could
not be built from a fresh clone.
Verified against the bf-53ut acceptance criteria:
- gcc -std=c11 -Wall -Wextra (-Werror): clean; no -Wclobbered/setjmp warnings
- normal suite: PASS, exit 0
- failing test + later passing test: both per-test lines print, process
completes (non-fatal assertions)
- no changes to firmware/main/* or firmware/CMakeLists.txt

# Build & run the whole suite, in one command, from the repo root:

#
|
|
# make -C firmware/test test
|
|
#
|
|
# That compiles every test_*.c in this directory together with test_runner.c
|
|
# using plain gcc (no ESP-IDF toolchain) and runs the resulting binary. The
|
|
# runner returns non-zero if ANY assertion fails, and make propagates that exit
|
|
# code, so the command is safe to wire straight into CI.

# See test_runner.h for the gcc-harness rationale (decision record: bead bf-21t;
