A player is a blend across independent axes, not one label. Skubal is a STARTER
and a strikeout arm and a ground-ball arm and a control arm — four true things
at once, and single-label classification threw three of them away.
AXIS INDEPENDENCE WAS MEASURED, NOT ASSUMED. Correlations over the live store
(467 batters, 531 pitchers); anything |r| >= 0.70 is one underlying trait and
was collapsed so we never show one trait as two archetypes. Batter k% ~ whiff%
+0.89, hard-hit% ~ exit velo +0.88, chase% ~ swing% +0.87, chase% ~ bb% -0.72;
pitcher k% ~ whiff% +0.76, gb% ~ fb% -0.73 — all collapsed.
The survivors are genuinely orthogonal, and one result is worth stating: pitcher
velocity correlates +0.14 with K%, +0.07 with whiff% and +0.07 with GB%.
Velocity is NOT a proxy for missing bats — a hard thrower who misses no bats is
a real distinct type, so CANNON earns its own axis rather than being folded into
STRIKEOUT. Pitcher K% ~ GB% is -0.10, so PUNCHOUT and SINKER are independent,
which is exactly the multi-axis thesis.
Cut-lines are the measured p75 (distinctive) and p90 (elite), per role where the
tails differ even when the medians agree: reliever GB% p90 is 54.1 against a
starter's 48.9, both with a median of 42.5.
THE FALLBACK IS DELETED. classify() used to return FLEX (mlb) / SHIELD (wnba) /
CONNECTOR (nba) at weight 1.0 when nothing scored — "could not classify"
rendered as a fully-confident classification of a real archetype, with
descriptive education copy attached. 8 of 18 MLB players carried it, and FLEX
could never be earned because its only scoring input had zero writers. Every
sport now does what MMA already did: unclassified is absent.
Induced on real players. Skubal: STARTER, throws L, WHIFF + SEAM + PINPOINT, all
elite. Judge: BOMBER + GRINDER + WHIFF RISK — elite power, patient, strikes out,
three true things. Kwan: SURGEON + SNIPER + SLASH with NO power claimed (0.4
barrel% is absent, not "low power"). Josh Bell, who used to classify as DRIVER:
empty blend, "No standout profile — league-average across every measured axis."
Alan Roden, who was FLEX at weight 1.0 on 21 PA: every axis absent, "Not enough
plate appearances yet — no profile claimed."
Per-axis honest-absence holds: a velo-less pitcher keeps every other axis, and
NO DATA is distinguishable from LEAGUE-AVERAGE rather than collapsing into one
shrug. The full vector is stored for Layer 3; only the top three distinctive
traits surface.
Three existing tests asserted the fallback and were updated to assert absence.
One of them surfaced a real robustness gap: classify(sport, null) threw, because
an explicit null does not trigger a default parameter and every scorer
dereferences its argument. Guarded.
Every baseball name is accounted for in docs/ARCHETYPE-AXES.md — built, alias,
tier, or shelved with its unlock condition. Zero orphans; cross-sport names left
for their sport.
Tests 3601 passed / 293 suites.

Design Rev 3 drew the 9 legacy classifier marks (BRUSH #E0B84A, WHIFF #E86A6A,
CONNECTOR #9AB0C4, DISTRIBUTOR #7AB8D8, FASTBREAK #4AA0E8, FLEX #A08AC8,
HYBRID #C88AB0, SWITCH #C0B08A, SWITCHBOARD #90A0E8). Wired each to its own
Design mark + color (front lib/archetypes.js + backend archetypeService.js,
color-synced). These were the 9 NO-MARK backend keys — now none are on a
generic placeholder. They're classifier-side fallback renders (never
user-facing archetype names, per MANIFEST).
Re-imported Rev 3 package over specs/design-reference/ (83 glyph SVGs + MANIFEST
regenerated from the authoritative glyphDefs(); HANDOFF Rev 3 note).

Replaced the generic reused shapes (triangle/star/plus/bolt…) with Design's
real per-archetype marks from the authoritative glyphDefs() (HANDOFF), and
aligned each archetype's color to Design's deduped palette — frontend
lib/archetypes.js + backend archetypeService.js kept in color-sync (the
cross-file test iterates the backend set). Badge test color expectations
updated to Design (BOMBER #FF9F45, CONDUCTOR #6C8CFF, ALPHA #7C5CFF,
FORTRESS #4C6FA5, …).
Scope + honesty:
- 29 non-combat archetypes wired to real marks + Design colors.
- COMBAT namespace (STRIKER/GRAPPLER/PRESSURE/COUNTER/FINISHER/GRINDER) left
untouched — it uses unicode CHAR glyphs + its own pinned colors + test
(FINISHER deliberately doesn't collide with the soccer FINISHER). Combat
could adopt Design's SVG marks in a follow-up.
- 39 Design marks are INERT (no classify() producer yet) — the 74 SVGs live in
specs/design-reference/assets/glyphs/; they light up when classify() expands.
- 9 backend archetypes have NO Design mark (BRUSH/CONNECTOR/DISTRIBUTOR/
FASTBREAK/FLEX/HYBRID/SWITCH/SWITCHBOARD/WHIFF) — kept on their generic glyph,
flagged for Design.
VISUALLY UNVERIFIED at 390px/desktop — archetype marks + colors on the audit list.

Signal-green #00D4A0 now means exactly ONE thing (edge/active/A-tier/CTA),
locked by tests that fail on violation. Part 1 of DESIGN-SPEC v2.
- web/src/lib/colorContract.js — pure CommonJS helpers: edgeColor(value)
colors edge/CLV/delta by SIGN (neg=var(--miss), pos=var(--g-a), 0=neutral);
gradeTierColor() (A/A+ green, B blue, C amber, D/F red, in lockstep with
vyndrTokens.gradeColor); gradeGlows() (A/A+ only); deltaE()/isSignalGreen()
CIE76 gate so no archetype hue dilutes the signal.
- GradeResultCard: edge confidence-strip + EDGE row route through edgeColor
(a -33.3% edge was rendering GREEN — audit #3); grade-hero glow gated to
A/A+ via gradeGlows (a glowing C devalued the cue); VYNDR INTELLIGENCE
panel de-flooded (neutral border, Form/Rest neutral not green — #15).
- LiveHeroProp: negative edge now muted red, not neutral (sign completeness).
- Archetype dedup off signal-green (both archetypes.js + archetypeService.js,
kept matched): DUAL THREAT/MOTOR #00D4A0, MIRROR #34D399, ARTILLERY/RANGE/
GHOST/BLADE #2DD4BF, BRUSH #3DDC84 shifted to distinct non-green hues (all
ΔE>=44 from #00D4A0). Within-sport uniqueness preserved.
- tests/unit/colorContract.test.js — 21 tests: helper units + source-grep
violation locks + archetype-green-dedup. QA.20-22 kept green.

- Name normalization completed: NICKNAMES table (Matt↔Matthew, Mike↔Michael...)
resolved in nameKey, parenthetical team-tag strip "(STL)", verified accent-fold
(Iván/Ivan, José/Jose). Slate strip now DISPLAYS the normalized de-dotted name
("AJ Ewing" not "A.J. Ewing") via buildPlayerStripsFromProps.
- Complete MLB VYNDR INTELLIGENCE: mlbGameLogFeatures derives rest_days (days off
between latest games; 0=B2B) + ab_per_game (usage). buildIntelFields renders
usage as "X AB/G", rest as B2B/Xd, matchup from bvp_advantage fallback.
- Ticker SCAN dedup: pushTickerItems keeps one SCAN per sport (sport field or
text-prefix parse for legacy); MOVE/GRADE preserved; cap 50.
- BOMBER threshold prorated for mid-season (hr>=15 strong / >=10 mod) so June
sluggers classify BOMBER not FLEX/DRIVER.
Backend 2122 -> 2149 tests (+27), 179 suites. Web build clean (exit 0).
