Slot Attachments

Attach location, app blocks, and verification rules to each time slot independently.

Per-Time-Slot Attachments

Each time slot in a commitment is not just a time range — it’s an independent enforcement container. You can attach different locations, app blocklists, and verification rules to each slot.

How Attachments Work

Each TimeSlotCard displays three attachment buttons:

Attachment	Icon	What it Does
Location	📍	Sets where you must be during this slot
App Block	📱	Sets which apps/websites are blocked during this slot
Rules	⚙️	Sets verification behavior (Just Show Up vs Stay Throughout)

Tapping an attachment button opens a Preset Picker Modal — a bottom sheet that lists your saved presets for that category.

Attachment Independence

The critical design principle is slot-level independence. Within the same commitment:

Morning Gym Slot (6:00 AM – 8:00 AM):

• Location: Fitty Gym VIT
• App Block: None
• Rule: Just Show Up, 10-min grace

Evening Library Slot (5:00 PM – 9:00 PM):

• Location: University Library
• App Block: Instagram, YouTube, Twitter (from “Social Media” preset)
• Rule: Stay Throughout, strict intensity, max 1 missed

State Management

Attachments are stored directly on the time slot object inside the Zustand draft store, keyed by slot index:

// Attaching a location preset to slot 0
setSlotLocation(0, {
  id: preset._id,
  latitude: preset.lat,
  longitude: preset.lng,
  radius: preset.radius,
  address: preset.address,
  isInverse: false,
});

// Attaching a digital blocklist preset to slot 1
setSlotBlocklist(1, {
  id: preset._id,
  apps: preset.apps,
  websites: preset.websites,
});

// Attaching a behavioral rule preset to slot 0
setSlotRule(0, {
  id: preset._id,
  name: preset.title || preset.name,
  config: preset.config,
});

Detaching a preset is done by passing null, which clears the attachment without affecting other slots.
