EVT 2026-03-01 - AI Tutor Wave 2 Contract Closure

Session scope

• Discovery root: docs/Domains/DOL English/Product Discovery/
• Lane lock: DOL English V2
• Collaboration mode: autonomous (user approved self-loop to DoD)
• Objective: close all Wave 2 open questions for AI Tutor logic and Smart Search handoff continuity.

Confirmed outcomes

1. Mobile payload compression policy for AI Inline -> AI Tutor handoff

• Keep required minimum packet fields always.
• Add deterministic payload tiers (full, balanced, lite) with clipping/capping rules.
• Compression never blocks chat opening; fallback seed remains mandatory.

2. AI Thi thử Full Test intent mapping policy

• Do not create new intent in v1.
• Use canonical intent ACT_TEST with AI inline feature variant AIF_MOCK_FULL_TEST.
• Preserve taxonomy stability while allowing AI-specific mock-test UX.

3. Diagram/mindmap rendering contract

• Use layered rendering policy:
  • native visual when renderer/device supports,
  • structured text graph fallback when visual unavailable,
  • concise checklist fallback when complexity/performance gates fail.

4. Provenance visibility depth contract

• Add three display depths (compact, standard, detailed).
• Use segment-based defaults with detailed always available on-demand.
• If general_fallback, disclosure is mandatory at all depth levels.

5. Sandbox exception policy for coaching integrity

• Active graded attempt remains strict no-final-answer zone.
• Exception applies only for explicit non-graded sandbox context with label sample/reference and no score/streak impact.

Open items after Wave 2

• No blocker-level open questions remain for AI Tutor core logic.
• Future optimization items are implementation-level (not decision blockers).
