gate_w1 amendment 2 flip: demote family-A concept cells + C1 to report-only (ratified c50f8bb) (#174)

Applies the ratified section-7 flip text 1:1 to gates.gate_w1: the six
family-A cells move from view tolerances to report_only with per-cell
machine reasons and retained_tolerances (zero threshold movement); the
faithful-candidate OC updates to the 47-cell surface (0.9344/0.9623);
the fresh-run cube shape narrows to [20, 47, 5]; family C demotes the
C1 (ppi_nra) fingerprint to report-only (fingerprint_reversal_not_realized)
and gates C2 alone; covers/certification_scope roll-ups move to
48 gated / 84 report-only; the amendment-2 history entry is appended
with the full five-round ceremony record. Partition-binding tests
polarity-flip to the amended surface; the proposal's untouched-guard
becomes the section-7 subset master-compare (no sibling gate moves).

Ceremony: adversarial 4953763322 (AMEND) -> fixes 4953911698 ->
verification 4954135376 (FURTHER FIXES) -> fixes-2 4954294003 ->
re-verification 4954346300 (RATIFY AS-IS); ratified by merge of
PR #169 (squash c50f8bb).
