+### Added
+- CI: additional checks to improve stability and reproducibility.
+- Tests: broader coverage for validation and web flows.
+
+### Changed
+- Tests: refactored to use pytest assertions and cleaned up fixtures/utilities to reduce noise and deprecations.
+- Tests: HTTP-dependent tests now skip gracefully when the local web server is unavailable.
+
+### Fixed
+- Tests: reduced deprecation warnings and incidental failures; improved consistency and reliability across runs.
+
+## [2.2.10] - 2025-09-11
+
+### Changed
+- Web UI: Test Hand uses a default fanned layout on desktop with tightened arc and 40% overlap; outer cards sit lower for a full-arc look
+- Desktop Test Hand card size set to 280×392; responsive sizes refined at common breakpoints
+- Theme controls moved from the top banner to the bottom of the left sidebar; sidebar made a flex column with the theme block anchored at the bottom
+- Mobile banner simplified to show only Menu, title; spacing and gaps tuned to prevent overflow and wrapping
+
+### Fixed
+- Prevented mobile banner overflow by hiding non-essential items and relocating theme controls
+- Ensured desktop sizing wins over previous inline styles by using global CSS overrides; cards no longer shrink due to flex
+
+## [2.2.9] - 2025-09-10
+
+### Added
+- Dynamic misc utility land EDHREC keep range env docs and theme weighting overrides
+- Land alternatives randomization (12 suggestions from random top 60–100 window) and land-only parity filtering
+
+### Changed
+- Compose and README updated with new misc land tuning environment variables
+
+### Fixed
+- Step 5 scroll flicker at bottom for small grids (virtualization skip <80 items + overscroll containment)
+- Fetch lands excluded from misc land step; mono-color rainbow filtering improvements
+
+## [2.2.8] - 2025-09-10
+

+- Web UI enhancement with two-column layout, chips/tag UI, and real-time validation
+- EDH format compliance checking for include/exclude cards against commander color identity
+
+### Changed
+- **Test organization**: Moved all test files from project root to centralized `code/tests/` directory for better structure
+- **CLI enhancement: Enhanced help text with type indicators** - All CLI arguments now show expected value types (PATH, NAME, INT, BOOL) and organized into logical groups
+- **CLI enhancement: Ideal count arguments** - New CLI flags for deck composition: `--ramp-count`, `--land-count`, `--basic-land-count`, `--creature-count`, `--removal-count`, `--wipe-count`, `--card-advantage-count`, `--protection-count`
+- **CLI enhancement: Theme tag name support** - Theme selection by name instead of index: `--primary-tag`, `--secondary-tag`, `--tertiary-tag` as alternatives to numeric choices
+- **CLI enhancement: Include/exclude CLI support** - Full CLI parity for include/exclude with `--include-cards`, `--exclude-cards`, `--enforcement-mode`, `--allow-illegal`, `--fuzzy-matching`
+- **CLI enhancement: Console summary printing** - Detailed include/exclude summary output for headless builds with diagnostics and validation results
+- Enhanced fuzzy matching with 300+ Commander-legal card knowledge base and popular/iconic card prioritization
+- Card constants refactored to dedicated `builder_constants.py` with functional organization
+- Fuzzy match confirmation modal with dark theme support and card preview functionality
+- Include/exclude summary panel showing build impact with success/failure indicators and validation issues
+- Comprehensive Playwright end-to-end test suite covering all major user flows and mobile layouts

+- Enhanced list size validation UI with visual warning system (⚠️ over-limit, ⚡ approaching limit) and color coding
+- Legacy endpoint transformation maintaining exact message formats for seamless integration with existing workflows
+
+### Fixed
+- JSON config files are now properly re-exported after bracket compliance enforcement and auto-swapping
+- Mobile horizontal scrolling issues resolved with global viewport overflow controls
+- Mobile UI setup status stuttering eliminated by removing temporary "Setup complete" message displays
+- Mobile build controls accessibility improved with bottom-floating positioning for thumb navigation
+- Mobile viewport breakpoint expanded from 720px to 1024px for broader device compatibility
+- Docker image: expanded entrypoint seeding now copies all default card list JSON files (extra_turns, game_changers, mass_land_denial, tutors_nonland, etc.) and brackets.yml when missing, preventing missing list issues with mounted blank config volumes
+
+## [2.2.6] - 2025-09-04
+
+### Added
+- Bracket policy enforcement: global pool-level prune for disallowed categories when limits are 0 (e.g., Game Changers in Brackets 1–2). Applies to both Web and headless runs.
+- Inline enforcement UI: violations surface before the summary; Continue/Rerun disabled until you replace or remove flagged cards. Alternatives are role-consistent and exclude commander/locked/in-deck cards.
+- Auto-enforce option: `WEB_AUTO_ENFORCE=1` to apply the enforcement plan and re-export when compliance fails.
+
+### Changed
+- Spells and creatures phases apply bracket-aware pre-filters to reduce violations proactively.
+- Compliance detection for Game Changers falls back to in-code constants when `config/card_lists/game_changers.json` is empty.
+- Data refresh: updated static lists used by bracket compliance/enforcement with current card names and metadata:
+  - `config/card_lists/extra_turns.json`
+  - `config/card_lists/game_changers.json`
+  - `config/card_lists/mass_land_denial.json`
+  - `config/card_lists/tutors_nonland.json`
+  Each list includes `list_version: "manual-2025-09-04"` and `generated_at`.
+
+### Fixed
+- Summary/export mismatch in headless JSON runs where disallowed cards could be pruned from exports but appear in summaries; global prune ensures consistent state across phases and reports.
+
+### Notes
+- These lists underpin the bracket enforcement feature introduced in 2.2.5; shipping them as a follow-up release ensures consistent results across Web and headless runs.
+
+## [2.2.5] - 2025-09-03
+
+### Added
+- Bracket WARN thresholds: `config/brackets.yml` supports optional `<category>_warn` keys (e.g., `tutors_nonland_warn`, `extra_turns_warn`). Compliance now returns PASS/WARN/FAIL; low brackets (1–2) conservatively WARN on presence of tutors/extra_turns when thresholds aren’t provided.
+- Web UI compliance polish: the panel auto-opens on non-compliance (WARN/FAIL) and shows a colored overall status chip (green/WARN amber/red). WARN items now render as tiles with a subtle amber style and a WARN badge; tiles and enforcement actions remain FAIL-only.
+- Tests: added coverage to ensure WARN thresholds from YAML are applied and that fallback WARN behavior appears for low brackets.
+
+### Changed
+- Web: flagged metadata now includes WARN categories with a `severity` field to support softer UI rendering for advisory cases.
+
+## [2.2.4] - 2025-09-02
+
+### Added
+- Mobile: Collapsible left sidebar with persisted state; sticky build controls adjusted for mobile header.
+- New Deck modal integrates Multi-Copy suggestions (opt-in) and commander/theme preview.
+- Web: Setup/Refresh prompt modal shown on Create when environment is missing or stale; routes to `/setup/running` (force on stale) and transitions into the progress view. Template: `web/templates/build/_setup_prompt_modal.html`.
+- Orchestrator helpers: `is_setup_ready()` and `is_setup_stale()` for non-invasive readiness/staleness checks from the UI.
+- Env flags for setup behavior: `WEB_AUTO_SETUP` (default 1) to enable/disable auto setup, and `WEB_AUTO_REFRESH_DAYS` (default 7) to tune staleness.
+- Step 5 error context helper: `web/services/build_utils.step5_error_ctx()` to standardize error payloads for `_step5.html`.
+- Templates: reusable lock/unlock button macro at `web/templates/partials/_macros.html`.
+- Templates: Alternatives panel partial at `web/templates/build/_alternatives.html` (renders candidates with Owned-only toggle and Replace actions).
+
+### Tests
+- Added smoke/unit tests covering:
+  - `summary_utils.summary_ctx()`
+  - `build_utils.start_ctx_from_session()` (monkeypatched orchestrator)
+  - `orchestrator` staleness/setup paths
+  - `build_utils.step5_error_ctx()` shape and flags
+
+### Changed
+- Mobile UI scaling and layout fixed across steps; overlap in DevTools emulation resolved with CSS variable offsets for sticky elements.
+- Multi-Copy is now explicitly opt-in from the New Deck modal; suggestions are filtered to only show archetypes whose matched tags intersect the user-selected themes (e.g., Rabbit Kindred shows only Hare Apparent).
+- Web cleanup: centralized combos/synergies detection and model/version loading in `web/services/combo_utils.py` and refactored routes to use it:
+  - `routes/build.py` (Combos panel), `routes/configs.py` (run results), `routes/decks.py` (finished/compare), and diagnostics endpoint in `app.py`.
+- Create (New Deck) flow: no longer auto-runs setup on submit; instead presents a modal prompt to run setup/refresh when needed.
+- Step 5 builder flow: deduplicated template context assembly via `web/services/build_utils.py` helpers and refactored `web/routes/build.py` accordingly (fewer repeated dicts, consistent fields).
+- Staged build context creation centralized via `web/services/build_utils.start_ctx_from_session` and applied across Step 5 flows in `web/routes/build.py` (New submit, Continue, Start, Rerun, Rewind).
+- Owned-cards set creation centralized via `web/services/build_utils.owned_set()` and used in `web/routes/build.py`, `web/routes/configs.py`, and `web/routes/decks.py`.
+ - Step 5: replaced ad-hoc empty context assembly with `web/services/build_utils.step5_empty_ctx()` in GET `/build/step5` and `reset-stage`.
+ - Builder introspection: adopted `builder_present_names()` and `builder_display_map()` helpers in `web/routes/build.py` for locked-cards and alternatives, reducing duplication and improving casing consistency.
+ - Alternatives endpoint now renders the new partial (`build/_alternatives.html`) via Jinja and caches the HTML (no more string-built HTML in the route).
+
+### Added
+- Deck summary: introduced `web/services/summary_utils.summary_ctx()` to unify summary context (owned_set, game_changers, combos/synergies, versions).
+ - Alternatives cache helper extracted to `web/services/alts_utils.py`.
+
+### Changed
+- Decks and Configs routes now use `summary_ctx()` to render deck summaries, reducing duplication and ensuring consistent fields.
+- Build: routed owned names via helper and fixed `_rebuild_ctx_with_multicopy` context indentation.
+ - Build: moved alternatives TTL cache into `services/alts_utils` for readability.
+ - Build: Step 5 start error path now uses `step5_error_ctx()` for a consistent UI.
+  - Build: Extended Step 5 error handling to Continue, Rerun, and Rewind using `step5_error_ctx()`.
+
+### Fixed
+- Continue button responsiveness on mobile fixed (eliminated sticky overlap); Multi-Copy application preserved across New Deck submit; emulator misclicks resolved.
+- Banner subtitle now stays inline inside the header when the menu is collapsed (no overhang/wrap to a new row).
+- Docker: normalized line endings for `entrypoint.sh` during image build to avoid `env: 'sh\r': No such file or directory` on Windows checkouts.
+
+### Removed
+- Duplicate root route removed: `web/routes/home.py` was deleted; the app root is served by `web/app.py`.
+
+## [2.2.3] - 2025-09-01
+### Fixes
+- Bug causing basic lands to no longer be added due to combined dataframe not including basics
+
+### Changed
+- Logic for removal tagging causing self-targetting cards (e.g. Conjurer's Closet) to be tagged as removal
+
 ## [2.2.2] - 2025-09-01
 ### Fixed
 - Ensure default config files are available when running with bind-mounted config directories:

 # MTG Python Deckbuilder ${VERSION}
 
-## Highlights
+### Added
-- Combos & Synergies: detect curated two-card combos and synergies, surface them in a unified chip-style panel on Step 5 and Finished Decks, and preview both cards on hover.
+- CI improvements to increase stability and reproducibility of builds/tests.
-- Auto-Complete Combos: optional mode that adds missing partners up to a target before theme fill/monolithic spells so added pairs persist.
+- Expanded test coverage for validation and web flows.
 
-## What’s new
+### Changed
-- Detection: exact two-card combos and curated synergies with list version badges (combos.json/synergies.json).
+- Tests refactored to use pytest assertions and streamlined fixtures/utilities to reduce noise and deprecations.
-- UI polish:
+- HTTP-dependent tests skip gracefully when the local web server is unavailable.
-  - Chip-style rows with compact badges (cheap/early, setup) in both the end-of-build panel and finished deck summary.
-  - Dual-card hover: moving your mouse over a combo row previews both cards side-by-side; hovering a single name shows that card alone.
-- Ordering: when enabled, Auto-Complete Combos runs earlier (before theme fill and monolithic spells) to retain partners.
-- Enforcement:
-  - Color identity respected via the filtered pool; off-color or unavailable partners are skipped gracefully.
-  - Honors Locks, Owned-only, and Replace toggles.
-- Persistence & Headless parity:
-  - Interactive runs export these JSON fields and Web headless runs accept them:
-    - prefer_combos (bool)
-    - combo_target_count (int)
-    - combo_balance ("early" | "late" | "mix")
 
-## JSON (Web Configs) — example
+### Fixed
-```json
+- Reduced deprecation warnings and incidental test failures; improved consistency across runs.
-{
-  "prefer_combos": true,
-  "combo_target_count": 3,
-  "combo_balance": "mix"
-}
-```
 
-## Notes
+---
-- Curated list versions are displayed in the UI for transparency.
-- Existing completed pairs are counted toward the target; only missing partners are added.
-- No changes to CLI inputs for this feature in this release.
-- Headless: `tag_mode` supported from JSON/env and exported in interactive run-config JSON.
-
-## Fixes
-- Fixed an issue with the Docker Hub image not having the config files for combos/synergies/default deck json example
