Order B: retire edge_pct display. Promotion gate NOT passed — no flip.

THE PROMOTION WAS NOT PERFORMED. Champion grade path byte-identical (diff empty
across intelligence/, gradeSlateService, snapshotService). Projection, p_win and
the CLV instrument untouched.

REVIEW ZERO IS A GATE AND THREE OF FOUR PREREQUISITES FAIL:
  0.1 scores are ESTIMATED priors from the founding spec, not measured. The
      premise's cited values are not in the code either — the module holds
      nba:points .80 and mlb:total_bases .55; there is no NBA 0.72 and no WNBA
      score at all.
  0.2 VERSION-BOUNDARY TAG DID NOT LAND — config/modelEras.js has zero shading
      references. It was deliberately not applied twice (nothing had been
      promoted) and reported both times. The order's own rule says STOP.
  0.3 NO ROLLBACK FLAG EXISTS — zero occurrences of SHADING_ENABLED /
      EDGE_SHADING / shadingEnabled anywhere in src/.
  0.4 takeable tags DID land (migration 034, 1246/1254 rows). PASS.

AND THE APPROVED DELTA DOES NOT MATCH THE MEASURED ONE. Approved: 43.6% of
grades re-letter, efficient markets tighten and soft hold. Measured on all 1250
live rows: 97.4% change (1217), 79.8% move UP, 17.6% down, resulting in 79.0%
A-family (MLB 93.4%) against the champion's 0.2%. And rows_actually_shaded = 0
of 1250 — 96.5% of markets are unscored (f=1) and the one scored market present
is the anchor (f=1.0 by construction). The entire re-letter comes from switching
to edge-vs-fixed-bar grading, NOT from efficiency shading, which is inert on
this board. That is an unapproved grading-basis change riding along, which the
order's own "no new scaling changes riding along" guardrail forbids.

Flipping would re-letter 97.4% of an append-only public record, move 79.8% of
grades UP and mint A's on 79% of the board, on a letter whose measured
correlation with outcomes is r ~ 0.005 — the exact scenario the permanent
founder ruling forbids.

SHIPPED — ORDER B (independent of the promotion, and a live falsehood):
edge_pct display retired from GradeResultCard (confidence strip, EDGE stat cell
now honest-absent, alt-ladder rung) and SoccerGradeResult. DeskShowcase kept
(already honest). Computation and the board's signed-edge sort fallback SURVIVE
— deleting them would re-break the sort fixed on 2026-07-29; a test asserts all
three survive and the sort still orders agrees -> disagrees -> absent.

Fixed two build-breakers the retirement caused (orphaned edgeColor import,
orphaned edge_pct destructure; edge_pct stays on the props contract). Two
pre-existing tests superseded rather than deleted: they asserted the edge figure
is sign-coloured, and now assert the stronger property that no edge percentage
renders at all.

Floor: 314 suites / 3908 tests green (9 new), web build exit 0.
