MTG Python Deckbuilder ${VERSION}

Unreleased (Draft)

Added

- Tests: added `test_random_reroll_throttle.py` to guard reroll throttle behavior and `test_random_metrics_and_seed_history.py` to verify opt-in telemetry counters and seed history API output.
- Analytics: splash penalty counters recognize both static and adaptive reasons; compare deltas with the flag toggled.

• Random Mode curated pool now loads manual exclusions (config/random_theme_exclusions.yml), includes reporting helpers (code/scripts/report_random_theme_pool.py --write-exclusions), and ships documentation (docs/random_theme_exclusions.md). Diagnostics cards show manual categories and tag index telemetry.
• Added code/scripts/check_random_theme_perf.py guard that compares the multi-theme profiler (code/scripts/profile_multi_theme_filter.py) against config/random_theme_perf_baseline.json with optional --update-baseline.
• Random Mode UI adds a “Clear themes” control that resets Primary/Secondary/Tertiary inputs plus local persistence in a single click.
  • Diagnostics: Added /status/random_theme_stats and a diagnostics dashboard card surfacing commander/theme token coverage and top tokens for multi-theme debugging.
• Cache bust hooks tied to catalog refresh & tagging completion clear filter/preview caches (metrics now include last bust timestamps).
• Governance metrics: example_enforcement_active, example_enforce_threshold_pct (threshold default 90%) signal when curated coverage enforcement is active.
• Server authoritative mana & color identity fields (mana_cost, color_identity_list, pip_colors) included in preview/export; legacy client parsers removed.

Changed

Added

• Tests: added test_random_multi_theme_webflows.py validating reroll-same-commander caching and permalink roundtrips for multi-theme runs across HTMX and API layers.
• Multi-theme filtering now reuses a cached lowercase tag column and builds a reusable token index so combination checks and synergy fallback avoid repeated pandas .apply passes; new script code/scripts/profile_multi_theme_filter.py reports mean ~9.3 ms / p95 ~21 ms cascade timings on the current catalog (seed 42, 300 iterations).
• Splash analytics updated to count both static and adaptive penalty reasons via a shared prefix, keeping historical dashboards intact.
• Random full builds internally auto-set RANDOM_BUILD_SUPPRESS_INITIAL_EXPORT=1 (unless explicitly provided) to eliminate duplicate suffixed decklists.
• Preview assembly now pins curated example_cards then synergy_example_cards before heuristic sampling with diversity quotas (~40% payoff, 40% enabler/support, 20% wildcard) and synthetic placeholders only when underfilled.
• List & API filtering route migrated to optimized path avoiding repeated concatenation / casefolding work each request.
• Hover system consolidated to one global panel; removed fragment-specific duplicate & legacy large-image hover. Thumbnails enlarged & unified (110px → 165px → 230px). Hover activation limited to thumbnails; stability improved (no dismissal over flip control); DFC markup simplified to single with opacity transition.

Deprecated

• Price / legality snippet integration deferred to Budget Mode. Any interim badges will be tracked under logs/roadmaps/roadmap_9_budget_mode.md.
• Legacy client-side mana/color identity parsers are considered deprecated; server-authoritative fields are now included in preview/export payloads.

Fixed

• Resolved duplicate template environment instantiation causing inconsistent navigation globals in picker fragments.
• Ensured preview cache key includes catalog ETag preventing stale samples after catalog reload.
• Random build duplicate decklist exports removed; suppression of the initial builder auto-export prevents creation of *_1.csv / *_1.txt artifacts.

---

Added

• Theme whitelist governance (config/themes/theme_whitelist.yml) with normalization, enforced synergies, and synergy cap (5).
• Expanded curated synergy matrix plus PMI-based inferred synergies (data-driven) blended with curated anchors.
• Random UI polish: fallback notices gain accessible icons, focus outlines, and aria copy; diagnostics badges now include icons/labels; the theme help tooltip is an accessible popover with keyboard controls; secondary/tertiary theme inputs persist via localStorage so repeat builds start with previous choices.
• Test: test_theme_whitelist_and_synergy_cap.py validates enforced synergy presence and cap compliance.
• PyYAML dependency for governance parsing.

Changed

• Theme normalization (ETB -> Enter the Battlefield, Self Mill -> Mill, Pillow Fort -> Pillowfort, Reanimator -> Reanimate) applied prior to synergy derivation.
• Synergy output capped to 5 entries per theme (curated > enforced > inferred ordering).

Fixed

• Removed ultra-rare themes (frequency <=1) except those protected/always included via whitelist.
• Corrected commander eligibility: restricts non-creature legendary permanents. Now only Legendary Creatures (incl. Artifact/Enchantment Creatures), qualifying Legendary Artifact Vehicles/Spacecraft with printed P/T, or any card explicitly stating "can be your commander" are considered. Plain Legendary Enchantments (non-creature), Planeswalkers without the text, and other Legendary Artifacts are excluded.
