Speculative schema from initial Refractor design that was never used —
boosts are hardcoded in refractor_boost.py and tier visuals are embedded
in CSS templates. Both tables have zero rows on dev and prod.

When a card reaches a new Refractor tier during game evaluation, the
system now creates a boosted variant card with modified ratings. This
connects the Phase 2 Foundation pure functions (PR #176) to the live
evaluate-game endpoint.
Key changes:
- evaluate_card() gains dry_run parameter so apply_tier_boost() is the
sole writer of current_tier, ensuring atomicity with variant creation
- apply_tier_boost() orchestrates the full boost flow: source card
lookup, boost application, variant card + ratings creation, audit
record, and atomic state mutations inside db.atomic()
- evaluate_game() calls evaluate_card(dry_run=True) then loops through
intermediate tiers on tier-up, with error isolation per player
- Display stat helpers compute fresh avg/obp/slg for variant cards
- REFRACTOR_BOOST_ENABLED env var provides a kill switch
- 51 new tests: unit tests for display stats, integration tests for
orchestration, HTTP endpoint tests for multi-tier jumps, pitcher
path, kill switch, atomicity, idempotency, and cross-player isolation
- Clarified all "79-sum" references to note the 108-total card invariant

Implements all gap tests identified in the PO review for the refractor
card progression system (Phase 1 foundation).
TIER 1 (critical):
- T1-1: Negative singles guard in compute_batter_value — documents that
hits=1, doubles=1, triples=1 produces singles=-1 and flows through
unclamped (value=8.0, not 10.0)
- T1-2: SP tier boundary precision with floats — outs=29 (IP=9.666) stays
T0, outs=30 (IP=10.0) promotes to T1; also covers T2 float boundary
- T1-3: evaluate-game with non-existent game_id returns 200 with empty results
- T1-4: Seed threshold ordering + positivity invariant (t1<t2<t3<t4, all >0)
TIER 2 (high):
- T2-1: fully_evolved=True persists when stats are zeroed or drop below
previous tier — no-regression applies to both tier and fully_evolved flag
- T2-2: Parametrized edge cases for _determine_card_type: DH, C, 2B, empty
string, None, and compound "SP/RP" (resolves to "sp", SP checked first)
- T2-3: evaluate-game with zero StratPlay rows returns empty batch result
- T2-4: GET /teams/{id}/refractors with valid team and zero states is empty
- T2-5: GET /teams/99999/refractors documents 200+empty (no team existence check)
- T2-6: POST /cards/{id}/evaluate with zero season stats stays at T0 value=0.0
- T2-9: Per-player error isolation — patches source module so router's local
from-import picks up the patched version; one failure, one success = evaluated=1
- T2-10: Each card_type has exactly one RefractorTrack after seeding
All 101 tests pass (15 PostgreSQL-only tests skip without POSTGRES_HOST).

Complete rename of the card progression system from "Evolution" to
"Refractor" across all code, routes, models, services, seeds, and tests.
- Route prefix: /api/v2/evolution → /api/v2/refractor
- Model classes: EvolutionTrack → RefractorTrack, etc.
- 12 files renamed, 8 files content-edited
- New migration to rename DB tables
- 117 tests pass, no logic changes
