The ctest registration is now simply `testsuite` (label too; CI steps run `ctest -LE testsuite` / `-L testsuite`), with README/AGENTS updated. New coverage, and what it caught: - save_object.lpc's ".lpc" case caught a REAL heap-buffer-overflow on CI's clang+ASan RelWithDebInfo job: save_object() sized its buffer for the stripped name + ".o" but strcpy'd the UNSTRIPPED path -- the 4-byte ".lpc" strip overflows the 2-byte ".o" headroom (the legacy ".c" strip fit by coincidence; DEBUGMALLOC padding hid it from local ASan Debug runs). Fixed with a bounded copy, plus the pre-existing file[len-sel] underflow read guarded. Verified in the exact failing configuration (clang RelWithDebInfo sanitizer: file case + full suite). - replace_program.lpc (new; the efun had NO testsuite coverage): pins name matching -- extension-less resolves the inherited program's real .lpc file, explicit ".lpc" matches exactly, explicit ".c" of an .lpc-compiled parent errors, non-inherited program errors. This surfaced that pending replace_ob_t records tripped check_memory() between test files: they legitimately live until the backend's replace_programs() sweep, so they get a dedicated whitelisted TAG_REPLACE_OB (same pattern as TAG_SCRATCHPAD) instead of TAG_TEMPORARY. - dual_extension.lpc: the inherit-retry loop keeps the caller's exact spelling (a ".c" child inheriting an unloaded parent must reload as ".c", not fall back to its .lpc twin -- pins load_object's raw-spelling retry), and function_exists() strips a real ".c" suffix. - restore_object.lpc: ".lpc"/".c" argument spellings resolve the same ".o" save file. - std/harness.lpc: self-test of the failure-recording machinery (record/query/pop round-trip via the new master::pop_failure(), and the per-assertion check counter). Verified: testsuite x3 + ctest 297/297 (ASan Debug), full ctest (RelWithDebInfo), and the clang RelWithDebInfo sanitizer build. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
