🟡 Okay	base interval	no change
🔴 Weak	base ÷ 2, min 1 day	no change
❌ Blank	1 day	reset to Stage 1

Graduated exception: Blank on a graduated card → reset to Stage 3 only, not Stage 1.

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: —
- Review Count: 0
- Graduated: No

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

After Each Review — What to Update

Stage: [old → new]
Review Date: [new date]
Last Rating: [Strong / Okay / Weak / Blank]
Review Count: [increment by 1]
Graduated: [Yes if Stage just hit 6 with Strong, otherwise No]

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.
