title: Rule on the prop market shapes the taxonomy models nowhere
type: task
status: planned
description: >-
  Team period totals, odd/even, quarter-plus-full-time doubles and three-way markets have no
  analogue in the market-type taxonomy, and whether they belong is undecided. Two-sided
  first-touchdown markets were ruled 2026-10-09: no new type.

## Background

The 2026-09-04 taxonomy work completed the PERIOD axis for shapes already modelled, and deliberately left the shapes below out. They are a different question: which period a modelled shape is scoped to, versus whether a shape is modelled at all.

Standing out of scope, with volume measured over DraftKings since 2025-08-01:

- team period totals (subcategories 9583, 8480, and others)
- odd/even (9449, 10554)
- quarter-plus-full-time doubles and Halves Won (12625)
- three-way markets, about 8,048 markets across 10 subcategories
- the 1st-half non-alt player yardage types, 18883 and 18884, which would need coined values

Narrowed 2026-10-03: team first-half totals and half-time/full-time are now graded through [[███████████████████████-██████-██████-██████-██████████]].

Ruled 2026-10-09 — two-sided first-touchdown markets get no new type. Pinnacle's 407 single-player Yes/No markets stay under `GAME_PLAYER_FIRST_TOUCHDOWN_SCORER`. The ~9,000 untyped markets once thought to share that shape are mostly DraftKings 18514/18483 two-player "Either Player to Score 1st TD" markets, plus team-level 10508 and BetRivers team markets. DraftKings 18514/18483 stay declined until a multi-subject selection grain exists, carried on [[user:task/league/declare-prop-market-types-once.md]].

Every id above sits in `known_unmapped_subcategory_ids` in `libs-server/draftkings/draftkings-constants.mjs`. Removing an id from that set is what makes it reportable again.

## The ruling this task owes

Whether each shape is worth a market type at all. A type that nothing settles and no data view offers is carrying cost with no reader, so the answer may legitimately be no for some of them — but it should be a recorded decision rather than the silence it is today.

## Plan

- [ ] Decide per shape whether it enters the taxonomy, and record the reasoning (two-sided first-touchdown ruled 2026-10-09: no new type; the shapes listed above remain open)
- [ ] For those that do, coin the values beside their siblings and map the subcategories
- [ ] Remove the newly mapped ids from `known_unmapped_subcategory_ids`
- [ ] Re-run the mapper replay and confirm the seed shrinks by exactly the ids mapped
