**Released:** 2026-06-21

## What's in v0.2

### MLC Enrichment (new in v0.2)

**166 MLC player profiles** (`okf/scorebook/mlc/players/`) generated from Cricsheet CC BY 3.0 MLC match data (75 matches, 2023–2025):
- All-time career batting and bowling aggregates
- Phase splits: powerplay (overs 1–6), middle (overs 7–15), death (overs 16–20)
- Season-by-season records (2023, 2024, 2025)
- Role inference (batter/bowler/all-rounder)
- Canonical URLs at `players.cricketstudio.ai/leagues/mlc/players/{slug}`

**47 MLC leaderboard files** (`okf/scorebook/mlc/leaderboards/`):
- All-time and per-season leaderboards for batting (runs, SR, average, sixes, fours, boundary %)
- Bowling (wickets, economy, SR, dot-ball %)
- Powerplay, middle, and death-over phase leaderboards
- Most appearances
- Orange Cap and Purple Cap (all-time and per season)

**5 MLC venue files** (`okf/scorebook/mlc/venues/`) with match-data-backed stats:
- Grand Prairie Stadium, Church Street Park, Broward County Stadium, Seaview Cricket Ground, Prairie View

**6 enriched MLC team files** in `okf/scorebook/teams/`:
- All-time season-by-season records
- Head-to-head records vs all opponents
- Top run-scorer and wicket-taker from leaderboards

**10 MLC dossier entries** — verified Q&A patterns for MLC-specific questions.

### Bug Fixes

- Fixed dossier `# Example —` heading display: viewer already renders frontmatter `title` as H1; the body H1 was redundant and removed from all 33 dossier files.
- Fixed broken internal links in `okf/scorebook/venues/index.md` (old venue slugs → corrected slugs).
- Fixed validator duplicate slug detection: changed from filename-stem to `entity_id`-based deduplication (allows `orange-cap.md` to exist in both `metrics/` and `mlc/leaderboards/` with distinct entity IDs).
- Added `leaderboard` type to frontmatter schema enum.

### Schema Changes

- Added `leaderboard` type to `schema/frontmatter.schema.json` type enum.

## Conformance Level

Level 2 — Evidence-Backed. All MLC files carry `provenance` block, `source_boundary: public_open_data`, Cricsheet CC BY 3.0 attribution, `last_verified: 2026-06-21`.
