Research direction

Start with Tidepool's Makefile lines 16, 27, and 42, then read the B3 reproducer in /tmp/critic-ca3/REPORT.md. Run the reproducer and inspect the self-test plant; done means the counting slot remains intact after the stub build or the row reports FAIL|runtime-slot-replaced.

Description

area:gates found-by:critic kind:silent-wrong

Found by the blind critic on the #1275 consumer_acceptance shrink (round 3, c98a743). It is pre-existing: the old harness at 88ba928 also PASSes.

Problem. Tidepool's Makefile defines EIG := $(EIGS_DIR)/src/eigenscript (line 16), rebuilds with $(MAKE) -C $(EIGS_DIR) build (line 27) and runs $(EIG) (line 42). A plausible acceptance sequence would be smoke → build → test. That rebuild replaces the overlay's counting shim at src/eigenscript with a freshly built binary, and later tree-path calls are no longer counted or routed through the supplied candidate. Today's Tidepool acceptance command does not run build, so this is prospective, not observed in a wave.

Reproduce (dev box): see the B3 reproducer in /tmp/critic-ca3/REPORT.md.

Done when:

  • A consumer's make -C "$EIGS_DIR" build either leaves the counting slot intact (for example, the shim is re-installed after each consumer step, or the build target is redirected) or makes the row refuse by name (FAIL|runtime-slot-replaced).
  • A self-test plant runs a stub build that overwrites $EIGS_DIR/src/eigenscript and shows the named outcome.
