The index supervisor gate (cbm_index_supervisor_should_wrap) wrapped ANY
embedder of cbm_mcp_handle_tool: it resolved the CURRENT executable and
re-invoked it as '<self> cli --index-worker index_repository ...'. In a
test binary 'self' is the test runner, which ignores those args and
re-runs its suites instead, producing recursive spawn chains (observed
11-minute hangs, and multiplied kernel VM-map/memory load during the
2026-07-04 host panics). The gate is now opt-in: only a process that
called cbm_index_supervisor_mark_host() — the real binary's main(),
before any subcommand dispatch — may spawn workers. Embedders index
in-process by default; the test mains additionally pin
CBM_INDEX_SUPERVISOR=0 as belt-and-suspenders. Guarded by
index_supervisor_gate_requires_marked_host_issue845 (fork+alarm harness,
new spawn-count test hook; red on the old gate, green without the env
kill switch on the new one).
A supervised worker whose supervisor died also kept indexing as an
orphan: the parent-death watchdog only ran in MCP-server mode. run_cli
now starts the same watchdog (detached; on ppid change it only writes
to stderr and _exit(0)s, so it is safe outside server mode) when it
detects --index-worker. Guarded by tests/test_worker_watchdog.sh
(scripts/test.sh Step 5b): a CBM_TEST_HANG_ON busy-spin pins the worker
mid-index, the wrapper parent is killed, and the worker must self-exit
within 15s — red without the wiring, green with it.
Fixes#845.

On NixOS (and other non-FHS systems) /bin/bash does not exist, so
scripts with an absolute shebang fail to run. Switch the remaining
holdouts to /usr/bin/env bash: eleven scripts/*.sh,
test-infrastructure/run.sh, and the three Claude Code hook scripts
emitted by src/cli/cli.c (gate, session reminder, subagent reminder).
Distilled from PR #674, with parser-test coverage preserved: the
infra_parse_shell* fixtures in tests/test_pipeline.c intentionally keep
#!/bin/bash so absolute-path shebang extraction stays covered, and
tests/repro fixtures are untouched.
Also replace the GitHub-PAT-shaped fixture string flagged in the #674
thread with an obviously fake placeholder (ghp_FAKE...) that still
matches the ghp_ + 36-alnum secret detector.

verify_compiler() in scripts/env.sh ran `file` on the clang path and
grepped for arm64/universal. Nix's clang is a bash wrapper script, so
`file` reports "ASCII text executable" and the check falsely concluded
"x86_64 only", aborting before any compile. Replace it with a capability
probe: compile + link a trivial program for the target -arch and trust
the result — correct for wrapper scripts (Nix, ccache) and cross-compilers.
Make arch targeting explicit and toolchain-agnostic: export
ARCHFLAGS="-arch <arch>" from env.sh and fold it into CC/CXX in
Makefile.cbm via `override`, so it reaches every compile and link
(including the vendored objects) and survives a command-line CC=
override. This replaces the `arch -<arch> make` prefix, which cannot
work with Nix's fixed-target clang. Drop the now-redundant ARCH_PREFIX
from build/test/lint/repro.

The MSYS2 CLANG64 toolchain bakes its package-tracker URL
(https://github.com/msys2/MINGW-packages) into the static Windows .exe via
libc++/compiler-rt. The Layer 2 binary string audit flagged it as an
unauthorized URL, failing smoke-windows (both the standard and ui variants)
while Linux smoke stayed green. Add it to ALLOWED_URLS alongside the other
compiler/linker toolchain URLs (gcc.gnu.org, sourceware.org, launchpad).
Add tests/test_security_strings_allowlist.sh as a reproduce-first regression
guard: it reproduces the BLOCKED failure with a binary fixture and includes a
negative control proving a genuinely unauthorized URL is still rejected. Wired
into scripts/test.sh as Step 6.

Two reviewed external-fork contributions, re-implemented as clean maintainer code.
#406 / PR #407 (thanks @nvt-pankajsharma): a POSIX parent-death watchdog so the stdio MCP server exits when its launching parent dies instead of lingering on stdin. Refactors signal_handler into an idempotent request_shutdown(); a watchdog thread polls getppid() (500ms) and shuts down + exit(0) once the initial ppid (>1) changes; Windows unaffected (#ifndef _WIN32). The fork's getppid()<=1 startup early-exit was dropped (it could wrongly kill a legitimately-launched server during reparent races / in container launchers; the initial_ppid>1 guard already no-ops safely), and thread-create failure is now non-fatal (matches the watcher/HTTP background-thread policy). Adds tests/test_parent_watchdog.sh + scripts/test.sh wiring.
#413 / PR #414 (thanks @santanusinha): runtime log-level control via CBM_LOG_LEVEL (case-insensitive debug|info|warn|error|none, or numeric 0..4; unset/unknown leaves the level unchanged). getenv() before threads start (no race). Adds tests/test_log.c cases + README env-var row.
Four overload-scoring lookups (cbm_registry_lookup_method_by_types/_by_args, _symbol_by_types/_by_args) linear-scanned the entire project registry on every call site, ignoring the pre-built method_buckets/func_qn_buckets hash index that the by-name lookups already use. On a large C++ header (e.g. 10989 defs) that is O(calls x project_funcs) per file (~34s/file), so big codebases never finish indexing. Add a hashed fast path (O(overloads)) when the registry is finalized; preserve first-match semantics via lowest registration index (equivalence verified over 1606 lookups, 0 divergence); keep the linear fallback for un-finalized single-file registries so normal files are unaffected. Adds tests/test_cpp_index_hang.sh (scale-tier subprocess+timeout repro, opt-in via CBM_RUN_HANG_TEST).
- Use env: block instead of shell quoting for WIN32_LIBS in CI
- Forward WIN32_LIBS from environment in test.sh and build.sh
- Add skip_lint input to dry-run workflow for faster iteration
MinGW GCC does not ship ASan runtime on Windows. MSYS2 CLANG64
provides full sanitizer support via compiler-rt. All platforms
now run tests with ASan + UBSan — no exceptions.
- Fix GCC -O2 warnings: calloc for cf (maybe-uninitialized),
suppress stringop-truncation/alloc-size-larger-than (false positives),
guard louvain against negative node_count
- Default compiler: cc on macOS, gcc on Linux/Windows (fixes gcc-14
not found on MSYS2)
- Docker test infra now runs BOTH test (ASan) and build (-O2 -Werror)
- Add scripts/clean.sh, test.sh, build.sh, lint.sh as single source
of truth for local and CI builds (always clean, always parallel)
- Fix -Wmissing-braces: replace {{0}} with memset for struct arrays
- Fix -Wrestrict: use intermediate buffer for same-struct snprintf
- Update dry-run.yml and release.yml to use the new scripts
