What happened, and what did you expect?

Running the full ASan/UBSan test gate consistently fails daemon_runtime_disconnect_cancels_blocked_non_index_child_and_preserves_other_session at ASSERT(marker_published).

The test copies the sanitized test runner to a private PATH entry named git, starts detect_changes, and waits for that copied process to publish its PID. It gives the copied process a fixed 5-second readiness budget.

On this machine the sanitized test runner is about 421 MB and the isolated copied probe takes about 7 seconds to reach main and publish its marker. The test therefore fails before it initiates or observes the cancellation behavior it exists to verify.

I expected this readiness wait to be a liveness backstop that accommodates normal sanitizer startup overhead, rather than a timing assertion on process startup. The repository already has a shared CBM_SANITIZED predicate and uses sanitizer-specific timing budgets elsewhere.

Reproduction

1. Check out DeusData/codebase-memory-mcp@46ae198f on macOS 26.5.2 arm64.
2. Run scripts/test.sh.
3. The focused suite also reproduces it with scripts/test.sh --suites daemon_runtime.
4. Actual result:

   44 passed, 1 failed
   blocking git marker missing: image=/tmp/cbm-runtime-non-index-.../bin/git completed=0 status=0 response=
   FAIL tests/test_daemon_runtime.c:3812: ASSERT(marker_published)
   

5. Expected: allow the copied runner to finish normal sanitizer startup, then verify process-tree cancellation.

Suggested fix: retain the native 5/15-second readiness/request budgets, but use 60/90-second liveness budgets under CBM_SANITIZED. A passing test still proceeds immediately when the marker appears.

With that change:

daemon_runtime: 45 passed
full scripts/test.sh: 7555 passed, 0 failed, 8 skipped
=== All tests passed ===
