EVT 2026-02-21 - Stage G Vocabulary Lean Loop and Overload Governor Autocomplete

Session scope

Continue outside-in discovery with autonomous recommendations to improve user experience quality while keeping logic lean and scalable. This batch focuses on Vocabulary as the third core block after Home and Practice.

Confirmed outcomes (auto-recommended defaults)

1. Lean entry default for Vocabulary:

• from Home/summary surface, the default action should favor immediate learning, not deep navigation,
• primary action is Ôn ngay (5 phút) when user has due or focusable words.

2. Today Focus queue baseline:

• Vocabulary session starts from a Today Focus queue with priority ordering:
  • due review words from active lists,
  • valid practice-result suggestion payload,
  • program/course recommended words,
  • program trending fallback.
• queue surface shows only top 20 items for the day to reduce overwhelm.

3. Quick-start subset:

• quick-start subset defaults to 5 items for low-friction entry.

4. Overload governor:

• if due backlog exceeds 40, new-word intake is paused from Today Focus (kept in inbox),
• intake resumes when backlog returns to <=30.

5. Non-punitive continuity:

• unfinished Today Focus does not create penalty or forced debt behavior,
• next day rebuilds priority queue with the same policy.

Open items carried forward

• None for Stage G baseline lock.
