Player play-event numerology on Retrosheet plays — when season home-run or strikeout milestones align with calendar day-of-month, jersey number, or inning.

When to use: a known Retrosheet retro_id and optional season / game filter. Not for team roster stacks → get_team_chemistry. Not for a bare birth date → get_date. Overlay get_date(game_dt) yourself for day-card narrative.


Required	`retro_id` — Retrosheet id, e.g. `ohtas001`, `freef001` (not Lahman/BBRef ids like `ohtansh01`)
Optional	`season_yr` · `mode` (`season` default \| `spotlight` \| `career_summary`) · `lane` (`both` default \| `hr` \| `k`) · `tier_max` · `game_dt` · `limit`

Use get_plays_numerology for ohtas001 mode career_summary.

Example (teaching excerpt)

{
  "retro_id": "ohtas001",
  "full_name": "shohei ohtani",
  "mode": "career_summary",
  "lane": "both",
  "summary": {
    "hr_events": 292,
    "hr_day_eq": 10,
    "hr_any_pattern": 49,
    "seasons_with_hr_patterns": 7,
    "k_events": 698,
    "k_day_eq": 10,
    "k_any_pattern": 52,
    "seasons_with_k_patterns": 6
  }
}

Season mode returns events[] with pattern labels such as day=HR#, HR#=jersey, day=K#=jersey.

Errors

`error`	Meaning
`player_not_found`	Unknown `retro_id` (wrong id family, typo, or not in mart)
`missing_retro_id`	No `retro_id`
`missing_season_yr`	Season/spotlight mode without `season_yr`
`invalid_mode` / `invalid_lane` / `invalid_season_yr`	Bad enum or type

Notes

Retrosheet vs Lahman: Ohtani is ohtas001 on this tool. ohtansh01 returns player_not_found.
Teaching patterns only — population rates for day=HR# are near chance; use for verified moments, not prediction.
