-"""Phase-1 stubs for Briefs 6 (lexeme primitives) and 7 (lexicon loader).
-
-Replace the imports in :mod:`generate.comprehension.lifecycle` with the real
-modules once Briefs 6 and 7 land. Until then, this module provides a thin,
-deterministic surface that covers exactly the categories the Phase-1 reader
-needs to admit the five GSM8K train_sample question sentences listed in
-Brief 8 (ADR-0164.3 §Worked example follow-on).
-
-The stub embeds:
-
-* a minimal lexicon: the entries already present in
-  ``language_packs/data/en_core_math_v1/lexicon.jsonl`` are honored, plus a
-  small supplemental vocabulary explicitly named "Phase-1 reader
-  supplemental — to be folded into the math pack" so it does not pretend
-  to be ratified pack content.
-* a primitive scanner that covers numeric, time-amount, currency, and
-  sentence-terminator shapes. ADR-0164.1 §Seed primitive set defines the
-  full set; the stub implements the subset the question sentences need.
-
-Determinism: ``scan_primitive`` and ``lookup`` are pure functions over
-their inputs. The module-level lexicon dict is populated once at import
-time from a frozen literal and the on-disk lexicon file.
