{{Warning|1=This is a '''sandbox demonstration''' of the wiki's versioning system. It is not real documentation. See [[Sandbox/Version demo]] for the latest version.}}

== Notification system (v3.0) ==

Version 3.0 introduced '''templates''', '''delivery tracking''', and '''batching'''.

=== Channels ===

{| class="wikitable"
! Channel !! Added in !! Notes
|-
| Email || 1.0 || Now supports HTML templates
|-
| In-app || 2.0 || Now supports rich cards with actions
|-
| SMS || 2.0 || Template-based (character-count aware)
|-
| Push (mobile) || '''3.0''' || FCM / APNs via unified adapter
|-
| Webhook || '''3.0''' || For external integrations
|}

=== Template engine ===

Messages now use a Jinja2-like template language:

<syntaxhighlight lang="text">
Hello {{ recipient.name }},

Your appointment with Dr. {{ provider.name }} is confirmed for
{{ appointment.datetime | format_date }}.

{% if appointment.requires_fasting %}
⚠️ Please fast for 12 hours before your visit.
{% endif %}
</syntaxhighlight>

=== Delivery tracking ===

Every notification now records:

{| class="wikitable"
! Field !! Type !! Description
|-
| <code>status</code> || enum || <code>queued → sent → delivered → read → failed</code>
|-
| <code>attempts</code> || int || Number of delivery attempts
|-
| <code>delivered_at</code> || datetime || When the channel confirmed receipt
|-
| <code>read_at</code> || datetime || When the user opened/acknowledged
|-
| <code>error</code> || text || Last failure reason (if any)
|}

=== Batching ===

Notifications to large groups now batch automatically:

* Email: up to 500 per SES API call
* Push: up to 1000 per FCM multicast
* Configurable batch window (default: 30 seconds)

== What improved over 2.0 ==

* Rich templates instead of hardcoded strings
* Full delivery lifecycle tracking
* Push notifications for mobile apps
* Webhook channel for third-party systems
* Batch sends for high-volume scenarios

== Still missing ==

* No scheduling (send-at-time)
* No A/B testing of message variants
* No per-organization channel config (global only)
