Context

gloss-drill-export-all tags every entry for org-drill. The card type controls which direction(s) the drill quizzes — term-to-definition (recognition), definition-to-term (recall), or both.

Decision

Set :DRILL_CARD_TYPE: twosided on every exported entry. org-drill's twosided card type alternates direction on consecutive visits, so a single entry quizzes both directions over time.

No per-entry override in v1. Every entry exports as twosided.

Consequences

Positive.

• Tests both recognition and recall over time without doubling the deck size — one entry, both directions, alternated by org-drill's scheduler.
• No per-entry decision burden during gloss-add or gloss-drill-export.

Negative.

• Some terms make more sense one-directional. A user who saved "SBIR" → "Small Business Innovation Research" probably wants recognition only (acronym → expansion), not recall (expansion → acronym). v1 doesn't accommodate this.
• A future v2 may want a per-entry :DRILL_CARD_TYPE: override or a defcustom for the default. Both are additive changes.

Alternatives Considered

:DRILL_CARD_TYPE: simple (term → definition only). Rejected: half the value of the cards, and the user can always skip-back during drill if they don't want the reverse direction.

Two cards per entry, one each direction. Rejected: doubles the deck size; adds maintenance burden when an entry is edited (now two cards diverge).

Cloze cards. Rejected: needs a marked deletion in the body, which fights the "save once, drill forever" promise.
