Additive frontend. Backend untouched (git diff src/ = empty): no grade, model,
classifier or ledger change. Scope held to the row anatomy these three items
need — no System-artboard-wide rebuild. Push scoring untouched.
REVIEW ZERO — the two checks that decided whether these could be honest:
0.2 RATIONALE SOURCE — VERIFIED REAL. Live snapshot grades carry `reasoning`
and `kill_conditions_triggered`. The summary is built by analyzeViaEngine1
from the actual feature vector (l5/l20 averages, gap to the line, home/away,
opponent defensive rank, rest days) and kills carry real codes + reasons.
So the hover shows genuine grade truth, not a placeholder.
0.3 TEAM COLOURS — PARTIAL, and deliberately left partial. The System artboard
defines a colour pair for only 10 teams (BOS CHC CHI DEN LAD MIL MIN NYY PIT
SD), lifted verbatim; lib/teams.js holds ~80. The other ~70 are NOT invented
— a wrong team colour is a recognition error the user reads as fact. Unknown
teams get the honest-neutral chip (muted border, no colour claim), never a
guess and never a blank gap. Coverage is reported by coverage(), not hidden.
SHIPPED:
- web/src/lib/rowRationale.js — rationaleFor() returns real summary + kills, or
NULL. No generic fallback: an empty hover is honest, a manufactured "why" is a
fabricated model explanation. A locked/tier-gated reasoning is treated as
ABSENT rather than paraphrased or leaked, and a kill condition with no reason
explains nothing so it is dropped.
- web/src/lib/reveal.js — IntersectionObserver reveal that fires ONCE then
unobserves ("react to truth, then rest"), reuses D1-A's bootDelayMs for the
60ms stagger so there is ONE source of truth for the timing, and reveals
IMMEDIATELY when IntersectionObserver is absent (SSR/test) so a missing API can
never hide real content. Reduced motion is handled by the existing CSS, so the
row is visible either way.
- web/src/lib/teamChips.js — Rev-3 geometry (10px, 135deg, before the abbr,
inside the row) plus the ranked opacity ramp 1/.86/.64/.48 so chips dim with
their row. Swap-ready for licensed logos at the same size.
Floor: 318 suites / 3961 tests green (15 new), web build exit 0.
The three modules are pure and unit-locked; mounting them into the live row
components is a follow-up, and the visual result belongs in the Chrome audit.
