# boundary_scan.py allowlist — justified exceptions to the engine/config red line

# Format, one rule per line:
#   <path-substring>                  # allow every protected identifier in matching files
#   <path-substring>:<identifier>     # allow only that identifier in matching files
#   text after '#' is the required reason.

# Each entry is VISIBLE DEBT, not a silent exclusion. The gate still catches
# every new source/product literal that appears in any other engine file.

# Central per-product registry (id/layer/domain/classification/lineage/raw table).
# Pre-dates the gate; clearest externalisation candidate. See the "Known
# concentration" note in docs/principles/engine-config-red-lines.md.

# Doc-only mention in the module docstring illustrating the part-file snapshot
# pattern; not behavior, not a branch.
