 ## [Unreleased]
 
+### Editorial / Themes
+- Enforce minimum example_commanders threshold (>=5) in CI (Phase D close-out). Lint now fails builds when a non-alias theme drops below threshold.
+- Added enforcement test `test_theme_editorial_min_examples_enforced.py` to guard regression.
+- Governance workflow updated to pass `--enforce-min-examples` and set `EDITORIAL_MIN_EXAMPLES_ENFORCE=1`.
+- Clarified lint script docstring and behavior around enforced minimums.
+- (Planned next) Removal of deprecated alias YAMLs & promotion of strict alias validation to hard fail (post grace window).
+
 ### Added
-- Theme catalog Phase B: new unified merge script `code/scripts/build_theme_catalog.py` (opt-in via THEME_CATALOG_MODE=merge) combining analytics + curated YAML + whitelist governance with provenance block output.
-- Theme provenance: `theme_list.json` now includes `provenance` (mode, generated_at, curated_yaml_files, synergy_cap, inference version) when built via Phase B merge.
+- Phase D close-out: strict alias enforcement promoted to hard fail in CI (`validate_theme_catalog.py --strict-alias`) removing previous soft warning behavior.
+- Phase D close-out: minimum example commander enforcement (>=5) now mandatory; failing themes block CI.
+- Tagging: Added archetype detection for Pillowfort, Politics, Midrange, and Toolbox with new pattern & specific card heuristics.
+- Tagging orchestration: Extended `tag_by_color` to execute new archetype taggers in sequence before bracket policy application.
+- Governance workflows: Introduced `.github/workflows/editorial_governance.yml` and `.github/workflows/editorial_lint.yml` for isolated lint + governance checks.
+- Editorial schema: Added `editorial_quality` to both YAML theme model and catalog ThemeEntry Pydantic schemas.
+- Editorial data artifacts: Added `config/themes/description_mapping.yml`, `synergy_pairs.yml`, `theme_clusters.yml`, `theme_popularity_metrics.json`, `description_fallback_history.jsonl`.
+- Editorial tooling: New scripts for enrichment & governance: `augment_theme_yaml_from_catalog.py`, `autofill_min_examples.py`, `pad_min_examples.py`, `cleanup_placeholder_examples.py`, `purge_anchor_placeholders.py`, `ratchet_description_thresholds.py`, `report_editorial_examples.py`, `validate_description_mapping.py`, `synergy_promote_fill.py` (extension), `run_build_with_fallback.py`, `migrate_provenance_to_metadata_info.py`, `theme_example_cards_stats.py`.
+- Tests: Added governance + regression suite (`test_theme_editorial_min_examples_enforced.py`, `test_theme_description_fallback_regression.py`, `test_description_mapping_validation.py`, `test_editorial_governance_phase_d_closeout.py`, `test_synergy_pairs_and_metadata_info.py`, `test_synergy_pairs_and_provenance.py`, `test_theme_catalog_generation.py`, updated `test_theme_merge_phase_b.py` & validation Phase C test) for editorial pipeline stability.
+
+- Editorial tooling: `synergy_promote_fill.py` new flags `--no-generic-pad` (allow intentionally short example_cards without color/generic padding), `--annotate-color-fallback-commanders` (explain color fallback commander selections), and `--use-master-cards` (opt-in to consolidated `cards.csv` sourcing; shard `[color]_cards.csv` now default).
+- Name canonicalization for card ingestion: duplicate split-face variants like `Foo // Foo` collapse to `Foo`; when master enabled, prefers `faceName`.
+- Commander rebuild annotation: base-first rebuild now appends ` - Color Fallback (no on-theme commander available)` to any commander added purely by color identity.
+- Roadmap: Added `logs/roadmaps/theme_editorial_roadmap.md` documenting future enhancements & migration plan.
+- Theme catalog Phase B: new unified merge script `code/scripts/build_theme_catalog.py` (opt-in via THEME_CATALOG_MODE=merge) combining analytics + curated YAML + whitelist governance with metadata block output.
+- Theme metadata: `theme_list.json` now includes `metadata_info` (formerly `provenance`) capturing generation context (mode, generated_at, curated_yaml_files, synergy_cap, inference version). Legacy key still parsed for backward compatibility.
 - Theme governance: whitelist configuration `config/themes/theme_whitelist.yml` (normalization, always_include, protected prefixes/suffixes, enforced synergies, synergy_cap).
 - Theme extraction: dynamic ingestion of CSV-only tags (e.g., Kindred families) and PMI-based inferred synergies (positive PMI, co-occurrence threshold) blended with curated pairs.
 - Enforced synergy injection for counters/tokens/graveyard clusters (e.g., Proliferate, Counters Matter, Graveyard Matters) before capping.

 - Augmentation flag `--augment-synergies` to repair sparse `synergies` arrays (e.g., inject `Counters Matter`, `Proliferate`).
 - Lint upgrades (`code/scripts/lint_theme_editorial.py`): validates annotation correctness, filtered synergy duplicates, minimum example_commanders, and base-name deduping.
 - Pydantic schema extension (`type_definitions_theme_catalog.py`) adding `synergy_commanders` and editorial fields to catalog model.
+- Phase D (Deferred items progress): enumerated `deck_archetype` list + validation, derived `popularity_bucket` classification (frequency -> Rare/Niche/Uncommon/Common/Very Common), deterministic editorial seed (`EDITORIAL_SEED`) for stable inference ordering, aggressive fill mode (`EDITORIAL_AGGRESSIVE_FILL=1`) to pad ultra-sparse themes, env override `EDITORIAL_POP_BOUNDARIES` for bucket thresholds.
+- Catalog backfill: build script can now write auto-generated `description` and derived/pinned `popularity_bucket` back into individual YAML files via `--backfill-yaml` (or `EDITORIAL_BACKFILL_YAML=1`) with optional overwrite `--force-backfill-yaml`.
+- Catalog output override: new `--output <path>` flag on `build_theme_catalog.py` enables writing an alternate JSON (used by tests) without touching the canonical `theme_list.json` or performing YAML backfill.
+- Editorial lint escalation: new flags `--require-description` / `--require-popularity` (or env `EDITORIAL_REQUIRE_DESCRIPTION=1`, `EDITORIAL_REQUIRE_POPULARITY=1`) to enforce presence of description and popularity buckets; strict mode also treats them as errors.
+- Tests: added `test_theme_catalog_generation.py` covering deterministic seed reproducibility, popularity boundary overrides, absence of YAML backfill on alternate output, and presence of descriptions.
+- Editorial fallback summary: optional inclusion of `description_fallback_summary` in `theme_list.json` via `EDITORIAL_INCLUDE_FALLBACK_SUMMARY=1` for coverage metrics (generic vs specialized descriptions) and prioritization.
+- External description mapping (Phase D): curators can now add/override auto-description rules via `config/themes/description_mapping.yml` without editing code (first match wins, `{SYNERGIES}` placeholder supported).
 
 ### Changed
+- Archetype presence test now gracefully skips when generated catalog YAML assets are absent, avoiding false negatives in minimal environments.
+- Tag constants and tagger extended; ordering ensures new archetype tags applied after interaction tagging but before bracket policy enforcement.
+- CI strict alias step now fails the build instead of continuing on error.
+- Example card population now sources exclusively from shard color CSV files by default (avoids variant noise from master `cards.csv`). Master file usage is explicit opt-in via `--use-master-cards`.
+- Heuristic text index aligned with shard-only sourcing and canonical name normalization to prevent duplicate staple leakage.
+- Terminology migration: internal model field `provenance` fully migrated to `metadata_info` across code, tests, and 700+ YAML catalog files via automated script (`migrate_provenance_to_metadata_info.py`). Backward-compatible aliasing retained temporarily; deprecation window documented.
+- Example card duplication suppression: `synergy_promote_fill.py` adds `--common-card-threshold` and `--print-dup-metrics` to filter overly common generic staples based on a pre-run global frequency map.
 - Synergy lists for now capped at 5 entries (precedence: curated > enforced > inferred) to improve UI scannability.
 - Curated synergy matrix expanded (tokens, spells, artifacts/enchantments, counters, lands, graveyard, politics, life, tribal umbrellas) with noisy links (e.g., Burn on -1/-1 Counters) suppressed via denylist + PMI filtering.
 - Synergy noise suppression: "Legends Matter" / "Historics Matter" pairs are now stripped from every other theme (they were ubiquitous due to all legendary & historic cards carrying both tags). Only mutual linkage between the two themes themselves is retained.

 - `synergy_commanders` now excludes any commanders already promoted into `example_commanders` (deduped by base name after annotation).
 - Promotion logic ensures a configurable minimum (default 5) example commanders via annotated synergy promotions.
 - Regenerated per-theme YAML files are environment-dependent (card pool + tags); README documents that bulk committing the entire regenerated catalog is discouraged to avoid churn.
+- Lint enhancements: archetype enumeration expanded (Combo, Aggro, Control, Midrange, Stax, Ramp, Toolbox); strict mode now promotes cornerstone missing examples to errors; popularity bucket value validation.
+- Regression thresholds tightened for generic description fallback usage (see `test_theme_description_fallback_regression.py`), lowering allowed generic total & percentage to drive continued specialization.

+# Editorial Contribution Guide (Themes & Descriptions)
+
+## Files
+- `config/themes/catalog/*.yml` – Per-theme curated metadata (description overrides, popularity_bucket overrides, examples).
+- `config/themes/description_mapping.yml` – Ordered auto-description rules (first match wins). `{SYNERGIES}` optional placeholder.
+- `config/themes/synergy_pairs.yml` – Fallback curated synergy lists for themes lacking curated_synergies in their YAML.
+- `config/themes/theme_clusters.yml` – Higher-level grouping metadata for filtering and analytics.
+
+## Description Mapping Rules
+- Keep triggers lowercase; use distinctive substrings to avoid accidental matches.
+- Put more specific patterns earlier (e.g., `artifact tokens` before `artifact`).
+- Use `{SYNERGIES}` if the description benefits from reinforcing examples; leave out for self-contained archetypes (e.g., Storm).
+- Tone: concise, active voice, present tense, single sentence preferred unless clarity needs a second clause.
+- Avoid trailing spaces or double periods.
+
+## Adding a New Theme
+1. Create a YAML file in `config/themes/catalog/` (copy a similar one as template).
+2. Add `curated_synergies` sparingly (3–5 strong signals). Enforced synergies handled by whitelist if needed.
+3. Run: `python code/scripts/build_theme_catalog.py --backfill-yaml --force-backfill-yaml`.
+4. Run validator: `python code/scripts/validate_description_mapping.py`.
+5. Run tests relevant to catalog: `pytest -q code/tests/test_theme_catalog_generation.py`.
+
+## Reducing Generic Fallbacks
+- Use fallback summary: set `EDITORIAL_INCLUDE_FALLBACK_SUMMARY=1` when building catalog. Inspect `generic_total` and top ranked themes.
+- Prioritize high-frequency themes first (largest leverage). Add mapping entries or curated descriptions.
+- After lowering count, tighten regression thresholds in `test_theme_description_fallback_regression.py` (lower allowed generic_total / generic_pct).
+
+## Synergy Pairs
+- Only include if a theme’s YAML doesn’t already define curated synergies.
+- Keep each list ≤8 (soft) / 12 (hard validator warning).
+- Avoid circular weaker links—symmetry is optional and not required.
+
+## Clusters
+- Use for UI filtering and analytics; not used in inference.
+- Keep cluster theme names aligned with catalog `display_name` strings; validator will warn if absent.
+
+## Metadata Info & Audit
+- Backfill process stamps each YAML with a `metadata_info` block (formerly documented as `provenance`) containing timestamp + script version and related generation context. Do not hand‑edit this block; it is regenerated.
+- Legacy key `provenance` is still accepted temporarily for backward compatibility. If both keys are present a one-time warning is emitted. The alias is scheduled for removal in version 2.4.0 (set `SUPPRESS_PROVENANCE_DEPRECATION=1` to silence the warning in transitional automation).
+
+## Editorial Quality Status (draft | reviewed | final)
+Each theme can declare an `editorial_quality` flag indicating its curation maturity. Promotion criteria:
+
+| Status    | Minimum Example Commanders | Description Quality                          | Popularity Bucket | Other Requirements |
+|-----------|----------------------------|----------------------------------------------|-------------------|--------------------|
+| draft     | 0+ (may be empty)          | Auto-generated allowed                       | auto/empty ok     | None               |
+| reviewed  | >=5                        | Non-generic (NOT starting with "Builds around") OR curated override | present (auto ok) | No lint structural errors |
+| final     | >=6 (at least 1 curated, non-synergy annotated) | Curated override present, 8–60 words, no generic stem | present           | metadata_info block present; no lint warnings in description/examples |
+
+Promotion workflow:
+1. Move draft → reviewed once you add enough example_commanders (≥5) and either supply a curated description or mapping generates a non-generic one.
+2. Move reviewed → final only after adding at least one manually curated example commander (unannotated) and replacing the auto/mapped description with a handcrafted one meeting style/tone.
+3. If a final theme regresses (loses examples or gets generic description) lint will flag inconsistency—fix or downgrade status.
+
+Lint Alignment (planned):
+- draft with ≥5 examples & non-generic description will emit an advisory to upgrade to reviewed.
+- reviewed with generic description will emit a warning.
+- final failing any table requirement will be treated as an error in strict mode.
+
+Tips:
+- Keep curated descriptions single-paragraph; avoid long enumerations—lean on synergies list for breadth.
+- If you annotate synergy promotions (" - Synergy (Foo)"), still ensure at least one base (unannotated) commander remains in examples for final status.
+
+Automation Roadmap:
+- CI will later enforce no `final` themes use generic stems and all have `metadata_info`.
+- Ratchet script proposals may suggest lowering generic fallback ceilings; prioritize upgrading high-frequency draft themes first.
+
+## Common Pitfalls
+- Duplicate triggers: validator warns; remove the later duplicate or merge logic.
+- Overly broad trigger (e.g., `art` catching many unrelated words) – prefer full tokens like `artifact`.
+- Forgetting to update tests after tightening fallback thresholds – adjust numbers in regression test.
+
+## Style Reference Snippets
+- Archetype pattern: `Stacks auras, equipment, and protection on a single threat ...`
+- Resource pattern: `Produces Treasure tokens as flexible ramp & combo fuel ...`
+- Counter pattern: `Multiplies diverse counters (e.g., +1/+1, loyalty, poison) ...`
+
+## Review Checklist
+- [ ] New theme YAML added
+- [ ] Description present or mapping covers it specifically
+- [ ] Curated synergies limited & high-signal
+- [ ] Validator passes (no errors; warnings reviewed)
+- [ ] Fallback summary generic counts unchanged or improved
+- [ ] Regression thresholds updated if improved enough
+- [ ] Appropriate `editorial_quality` set (upgrade if criteria met)
+- [ ] Final themes meet stricter table requirements
+
+Happy editing—keep descriptions sharp and high-value.
+
+## Minimum Example Commanders Enforcement (Phase D Close-Out)
+As of Phase D close-out, every non-alias theme must have at least 5 `example_commanders`.
+
+Policy:
+* Threshold: 5 (override locally with `EDITORIAL_MIN_EXAMPLES`, but CI pins to 5).
+* Enforcement: CI exports `EDITORIAL_MIN_EXAMPLES_ENFORCE=1` and runs the lint script with `--enforce-min-examples`.
+* Failure Mode: Lint exits non-zero listing each theme below threshold.
+* Remediation: Curate additional examples or run the suggestion script (`generate_theme_editorial_suggestions.py`) with a deterministic seed (`EDITORIAL_SEED`) then manually refine.
+
+Local soft check (warnings only):
+```
+python code/scripts/lint_theme_editorial.py --min-examples 5
+```
+
+Local enforced check (mirrors CI):
+```
+EDITORIAL_MIN_EXAMPLES_ENFORCE=1 python code/scripts/lint_theme_editorial.py --enforce-min-examples --min-examples 5
+```
+
+## Alias YAML Lifecycle
+Deprecated alias theme YAMLs receive a single release grace period before deletion.
+
+Phases:
+1. Introduced: Placeholder file includes a `notes` line marking deprecation and points to canonical theme.
+2. Grace Period (one release): Normalization keeps resolving legacy slug; strict alias validator may be soft.
+3. Removal: Alias YAML deleted; strict alias validation becomes hard fail if stale references remain.
+
+When removing an alias:
+* Delete alias YAML from `config/themes/catalog/`.
+* Search & update tests referencing old slug.
+* Rebuild catalog: `python code/scripts/build_theme_catalog.py` (with seed if needed).
+* Run governance workflow locally (lint + tests).
+
+If extended grace needed (downstream impacts), document justification in PR.

 # MTG Python Deckbuilder ${VERSION}
 
+## Unreleased (Draft)
+
+### Added
+- Editorial duplication suppression for example cards: `--common-card-threshold` (default 0.18) and `--print-dup-metrics` flags in `synergy_promote_fill.py` to reduce over-represented staples and surface diverse thematic examples.
+- Optional `description_fallback_summary` block (enabled via `EDITORIAL_INCLUDE_FALLBACK_SUMMARY=1`) capturing specialization KPIs: generic vs specialized description counts and top generic holdouts.
+
+### Changed
+- Terminology migration: `provenance` renamed to `metadata_info` across catalog JSON, per-theme YAML, models, and tests. Builder writes `metadata_info`; legacy `provenance` key still accepted temporarily.
+
+### Deprecated
+- Legacy `provenance` key retained as read-only alias; warning emitted if both keys present (suppress via `SUPPRESS_PROVENANCE_DEPRECATION=1`). Planned removal: v2.4.0.
+
+### Fixed
+- Schema evolution adjustments to accept per-theme `metadata_info` and optional fallback summary without triggering validation failures.
+
+---
+
 ### 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.

  - deck_archetype membership in allowed set (warn if unknown)
- - Cornerstone themes have at least one example commander & card
+ - Cornerstone themes have at least one example commander & card (error in strict mode)

+ - Load all history records (JSON lines) that include generic_total & generic_pct.
+ - Use the most recent N (default 5) snapshots to compute a smoothed (median) generic_pct.
+ - If median is at least 2 percentage points below current test ceiling OR
+   the latest generic_total is at least 10 below current ceiling, propose new targets.
+ - Output JSON with keys: current_total_ceiling, current_pct_ceiling,
+   proposed_total_ceiling, proposed_pct_ceiling, rationale.
+
+Defaults assume current ceilings (update if test changes):
+   total <= 365, pct < 52.0
+
+Usage:
+  python code/scripts/ratchet_description_thresholds.py \
+      --history config/themes/description_fallback_history.jsonl

+"""Editorial population helper for theme YAML files.
+
+Features implemented here:
+
+Commander population modes:
+ - Padding: Fill undersized example_commanders lists (< --min) with synergy-derived commanders.
+ - Rebalance: Prepend missing base-theme commanders if list already meets --min but lacks them.
+ - Base-first rebuild: Overwrite lists using ordering (base tag -> synergy tag -> color fallback), truncating to --min.
+
+Example cards population (NEW):
+ - Optional (--fill-example-cards) creation/padding of example_cards lists to a target size (default 10)
+   using base theme cards first, then synergy theme cards, then color-identity fallback.
+ - EDHREC ordering: Uses ascending edhrecRank sourced from cards.csv (if present) or shard CSVs.
+ - Avoids reusing commander names (base portion of commander entries) to diversify examples.
+
+Safeguards:
+ - Dry run by default (no writes unless --apply)
+ - Does not truncate existing example_cards if already >= target
+ - Deduplicates by raw card name
+
+Typical usage:
+  Populate commanders only (padding):
+      python code/scripts/synergy_promote_fill.py --min 5 --apply
+
+  Base-first rebuild of commanders AND populate 10 example cards:

+          --fill-example-cards --cards-target 10 --apply
