Mode Assignment
Given card state, assign Full, Snippet, or Blitz:
- Last Rating Blank or Weak → Full (always, overrides everything)
- Stage 1, Last Rating — (never reviewed) → Full
- Stage 1–2, Last Rating Okay or Strong → Snippet
- Stage 3–4 → Snippet
- Stage 5–6 → Blitz
- Graduated → Blitz
SRS Tracking Block (required on every card)
## SRS Tracking
- Stage: 1
- Review Date: YYYY-MM-DD
- Last Rating: —

If a card is missing this block, flag it before the session and show the default values above.

Bail-Out Triggers
If I say timeout, blank, or no clue at any point during a problem → rate Blank, show full card immediately, move on.
