The Quat-flagged "≥3 tests per feature" inflation produced 43 tests
that don't earn their existence — default-value, serde-derive
round-trips on plain structs, single-field clamp tests, near-
duplicates, and trivial constant-equals-itself tests. None pin a
behaviour contract or a regression on a real bug.
Removed across `solitaire_data` and `solitaire_core`:
settings.rs −22 default-value, round-trip, legacy-format,
and per-field sanitized clamp tests. Adjust
and load-error tests retained — those exercise
real method logic.
progress.rs −1 generic round-trip on plain struct.
challenge.rs −1 challenge_count() returns CHALLENGE_SEEDS.len()
literally — testing it asserts the implementation
against itself.
game_state.rs −3 undo_count starts at 0, GameMode default is
Classic, time_attack score starts at 0 — all
default-value tests on freshly-constructed state.
card.rs −5 rank_value_ace + rank_value_king subsumed by
rank_values_are_sequential; suit_red + suit_black
consolidated into one complementarity test;
card_face_up_field_reflects_construction was
testing the struct literal.
Workspace: 1208 → 1165 passing tests (−43). clippy --workspace
--all-targets clean.
Future work: brief sub-agents for tests that pin a behaviour
contract or regression on a real bug, not a count of N. See
`feedback_test_discipline.md` in auto-memory.

Adds 4 more rounds of 5 seeds each, organized by difficulty tier.
Seeds wrap modulo list length so the pool grows non-destructively.

Phase 6 part 4b (partial):
- GameMode::Challenge variant in solitaire_core. undo() returns
RuleViolation when mode is Challenge so the player commits to each
decision.
- solitaire_data::challenge defines a stable CHALLENGE_SEEDS list with
challenge_seed_for(index) wrapping modulo length.
- PlayerProgress.challenge_index (serde-default for older saves) tracks
how far the player has progressed.
- ChallengePlugin advances the cursor on Challenge-mode wins, persists,
and emits ChallengeAdvancedEvent. Pressing X starts a Challenge-mode
game with the current seed; gated to level >= CHALLENGE_UNLOCK_LEVEL (5).
- InputPlugin's Z key (Zen mode) is now also gated to level >= 5.
Time Attack and unlock UI still deferred.
