Reverts the c3aed13b parser change (frame-anchored comparative regexes +
verb-free connector + _COMPARE_POLARITY_BLOCK + 'as much'); the reader stays
on the _comparison_anchor_verb() whitelist (fail-closed). Increment 1 ships
the compiler tier + the funnel finding only.
Three reasons on record: (1) frame-anchoring converts 0 of 500 official cases
— zero measured benefit today; (2) its consumer is rate-frame admission, a
later increment — the next increment (seeding-sentence injection) is a shared
layer that doesn't touch it; (3) the polarity blocklist is fail-OPEN — an
unenumerated depletion verb in a complete frame is a coherent-but-inverted
graph = a wrong on the run-once sealed arbiter (round-trip guards parse
consistency, not gold-correctness), a trade the fail-closed doctrine never
takes for zero gain.
Verified before revert-merge: with the whitelist reader, the 5 real compare
parses are non-divergent — test_real_compare_cases_solved_wrong_zero still
sees 5, solves 5, wrong 0 (corridor real-reach 0->5/500 preserved).
Frame-anchoring recorded as an OPEN DESIGN TASK owned by the rate-frame
increment: frame + POSITIVE polarity determination (neutral-polarity allowlist
or small polarity classifier), not assume-safe-unless-blocklisted. Detail in
