+SimpleX Chat protocol supports these message formats:
 
 - JSON-based format for chat and application messages.
+- compressed format for adapting larger messages to reduced size of message envelope, caused by addition of PQ encryption keys to SMP agent message envelope.

 ### JSON format for chat and application messages
 
 This document uses JTD schemas [RFC 8927](https://www.rfc-editor.org/rfc/rfc8927.html) to define the properties of chat messages, with some additional restrictions on message properties included in metadata member of JTD schemas.

 ## Sub-protocol for chat groups
 
 ### Decentralized design for chat groups
 
-SimpleX Chat groups are fully decentralized and do not have any globally unique group identifiers - they are only defined on client devices as a group profile and a set of bi-directional SimpleX connections with other group members. When a new member accepts group invitation, the inviting member introduces a new member to all existing members and forwards the connection addresses so that they can establish direct and group member connections.
+SimpleX Chat groups are fully decentralized and do not have any globally unique group identifiers - they are only defined on client devices as a group profile and a set of bi-directional SimpleX connections with other group members. When a new member accepts group invitation or joins via group link, the inviting member introduces a new member to all existing members and forwards the connection addresses so that they can establish direct and group member connections.
 
 There is a possibility of the attack here: as the introducing member forwards the addresses, they can substitute them with other addresses, performing MITM attack on the communication between existing and introduced members - this is similar to the communication operator being able to perform MITM on any connection between the users. To mitigate this attack this group sub-protocol will be extended to allow validating security of the connection by sending connection verification out-of-band.
 
-Clients are RECOMMENDED to indicate in the UI whether the connection to a group member or contact was made directly or via annother user.
+Clients are RECOMMENDED to indicate in the UI whether the connection to a group member or contact was made directly or via another user.
 
 Each member in the group is identified by a group-wide unique identifier used by all members in the group. This is to allow referencing members in the messages and to allow group message integrity validation.
 
 The diagram below shows the sequence of messages sent between the users' clients to add the new member to the group.
 
+While introduced members establish connection inside group, inviting member forwards messages between them by sending `x.grp.msg.forward` messages. When introduced members finalize connection, they notify inviting member to stop forwarding via `x.grp.mem.con` message.

+# Agent stats persistence
+
+## Problem
+
+State/state tracked in agent are lost on app restart, which makes it difficult to debug user bugs.
+
+## Solution
+
+Persist stats between sessions.
+
+App terminal signals may vary per platform / be absent (?) -> persist stats periodically.

+Stats would have `<userId, server>` key, so we don't want to store them in a plaintext file to not leak used servers locally -> persist in encrypted db.
+
+There's couple of orthogonal design decision to be made:
+- persist in chat or in agent db
+  - pros for chat:
+    - possibly less contention for db than agent
+  - pros for agent:
+    - no unnecessary back and forth, especially if agent starts accumulating from past sessions and has to be parameterized with past stats (see below)
+- agent to start accumulating from past sessions stats, or keep past separately and only accumulate for current session from zeros
+  - pros for accumulating from past sessions:
+    - easier to maintain stats - e.g. user deletion has to remove keys, which is more convoluted if past stats are not stored in memory
+    - simpler UI - overall stats, no differentiation for past/current session (or less logic in backend preparing presentation data)
+  - pros for accumulating from zeros:
+    - simpler start logic - no need to restore stats from agent db / pass initial stats from chat db
+    - can differentiate between past sessions and current session stats in UI
+
+### Option 1 - Persist in chat db, agent to track only current session
+
+- Chat stores stats in such table:
+
+```sql
+CREATE TABLE agent_stats(
+  agent_stats_id INTEGER PRIMARY KEY, -- dummy id, there will only be one record
+  past_stats TEXT, -- accumulated from previous sessions
+  session_stats TEXT, -- current session
+  past_started_at TEXT NOT NULL DEFAULT(datetime('now')), -- starting point of tracking stats, reset on stats reset
+  session_started_at TEXT NOT NULL DEFAULT(datetime('now')), -- starting point of current session
+  session_updated_at TEXT NOT NULL DEFAULT(datetime('now')) -- last update of current session stats (periodic, frequent updates)
+);
+```
+
+- Chat periodically calls getAgentServersStats api and updates `session_stats`.
+  - interval? should be short to not lose too much data, 5-30 seconds?
+- On start `session_stats` are accumulated into `past_stats` and set to null.
+- On user deletion, agent updates current session stats in memory (removes keys), chat has to do same for both stats fields in db.
+  - other cases where stats have to be manipulated in similar way?
+
+### Option 2 - Persist in chat db, agent to accumulate stats from past sessions
+
+- Table is only used for persistence of overall stats:
+
+```sql
+CREATE TABLE agent_stats(
+  agent_stats_id INTEGER PRIMARY KEY, -- dummy id, there will only be one record
+  agent_stats TEXT, -- overall stats - past and session
+  started_tracking_at TEXT NOT NULL DEFAULT(datetime('now')), -- starting point of tracking stats, reset on stats reset
+  updated_at TEXT NOT NULL DEFAULT(datetime('now'))
+);
+```
+
+- Chat to parameterize creation of agent client with initial stats.
+
+### Option 3 - Persist in agent db, agent to differentiate past stats and session stats
+
+- Table in agent db similar to option 1.
+- Agent is responsible for periodic updates in session, as well as accumulating into "past" and resetting session stats on start.
+- Agent only communicates stats to chat on request.
+- On user deletion agent is fully responsible for maintaining both in-memory session stats, and updating db records.
+
+### Option 4 - Persist in agent db, agent to accumulate stats from past sessions
+
+- Table in agent db similar to option 2.
+- On start agent restores initial stats into memory by itself.
+- Since all stats are in memory, on user deletion it's enough to update in memory without updating db.
+  - there is a race possible where agent crashes after updating stats (removing user keys) in memory before database stats have been overwritten by a periodic update, so it may be better to immediately overwrite and not wait for periodic update.
+  - still at least there's at least no additional logic to update past stats.
+
+### Other considerations
+
+Why is it important to timely remove user keys from past stats?
+- stats not being saved for past users:
+  - important both privacy-wise and to not cause confusion when showing "All" stats (e.g. user summing up across users stats would have smaller total than total stats).
+  - to avoid accidentally mixing up with newer users.
+    - though we do have an AUTOINCREMENT user_id in agent so probably it wouldn't be a problem.
+- on the other hand maybe we don't want to "forget" stats on user deletion so that stats would reflect networking more accurately?

+    <p>SimpleX - the first messaging platform that has no user identifiers, not even random numbers!</p>
+    <p>Security assessment was done by Trail of Bits in November 2022.</p>
+    <p>SimpleX Chat features:</p>
+    <ol>
+      <li>end-to-end encrypted messages, with editing, replies and deletion of messages.</li>
+      <li>sending end-to-end encrypted images and files.</li>
+      <li>single-use and long-term user addresses.</li>
+      <li>secret chat groups - only group members know it exists and who is the member.</li>
+      <li>end-to-end encrypted audio and video calls.</li>
+      <li>private instant notifications.</li>
+      <li>portable chat profile - you can transfer your chat contacts and history to another device (terminal or mobile).</li>
+    </ol>
+    <p>SimpleX Chat advantages:</p>
+    <ol>
+      <li><em>Full privacy of your identity, profile, contacts and metadata:</em> unlike any other existing messaging platform, SimpleX uses no phone numbers or any other identifiers assigned to the users - not even random numbers. This protects the privacy of who you are communicating with, hiding it from SimpleX platform servers and from any observers.</li>
+      <li><em>Complete protection against spam and abuse:</em> as you have no identifier on SimpleX platform, you cannot be contacted unless you share a one-time invitation link or an optional temporary user address.</li>
+      <li><em>Full ownership, control and security of your data:</em> SimpleX stores all user data on client devices, the messages are only held temporarily on SimpleX relay servers until they are received.</li>
+      <li><em>Decentralized network:</em> you can use SimpleX with your own servers and still communicate with people using the servers that are pre-configured in the apps or any other SimpleX servers.</li>
+    </ol>
+    <p>You can connect to anybody you know via link or scan QR code (in the video call or in person) and start sending messages instantly - no emails, phone numbers or passwords needed.</p>
+    <p>Your profile and contacts are only stored in the app on your device - our servers do not have access to this information.</p>
+    <p>All messages are end-to-end encrypted using open-source double-ratchet protocol; the messages are routed via our servers using open-source SimpleX Messaging Protocol.</p>
