AI Tutor reminder quiet-hours, active-plan singleton, and deeplink policy

DEC-0030 - AI Tutor reminder quiet-hours, active-plan singleton, and deeplink policy

Context

After locking reminder timing and edge rules, the product still needs clear boundaries for send window, plan concurrency, and post-click destination.

Decision

Quiet-hours policy:

• AI Tutor daily required reminder follows the same system quiet-hours policy already used by notification engine.

Active plan singleton:

• Each account can have only one active AI Tutor 7-day plan at a time.
• New plan activation replaces/closes previous active plan.

Reminder deeplink:

• Reminder click opens Practice Management.
• The screen highlights today’s required item for immediate action.

Decision Value

• Quiet-hours reuse solves “right message, wrong time” risk without introducing a second notification policy stack.
• One active plan per account solves plan-conflict risk and keeps completion/exit logic measurable from one source of truth.
• Deeplink to highlighted required item solves post-click friction and improves probability of completing intended action.

Rationale

These rules preserve a simple mental model for learners and reduce operational branching. The reminder engine stays predictable, and plan progress semantics remain stable across channels and devices.
