Audit Twitch chat message ingestion and timestamping in TarkovAI

segment 1 of 5
Locate and analyze ConsumeTwitchMessageJob for timestamp handling
Read the full ConsumeTwitchMessageJob source at app/Jobs/ConsumeTwitchMessageJob.php. The job creates a new ChatMessage model instance (line 123), sets message_body_id, twitch_user_id, and stream_id, then calls save() (line 181). It does NOT explicitly set created_at — Laravel's automatic timestamping inserts the current database time. The tmi-sent-ts IRC tag is extracted only for failure logging context (lines 277-286) and is never used to set created_at or any other column.
outcome
Confirmed that created_at on chat_messages reflects worker insert time, not Twitch send time. No explicit timestamp from the Twitch message is stored.

Examine ChatMessage model and chat_messages table schema for sent-time columns
Read the ChatMessage model at app/Models/ChatMessage.php — it has no $fillable, $casts, or accessors for any sent-time field. Read the current database schema from database/schema/mysql-schema.sql which shows the chat_messages table has only id, stream_id, twitch_user_id, message_body_id, created_at, and updated_at columns. Found the original migration (2023_12_23_173714_create_chat_messages_table.php) via git history which created the table with just stream_id, twitch_user_id, message, and timestamps. Found a later migration (2024_01_03_194200_add_message_body_id_to_chat_messages_table.php) that added message_body_id. No migration ever added a tmi-sent-ts, sent_at, or similar column.
outcome
The chat_messages table has no column for Twitch's send timestamp. Only Laravel's automatic created_at and updated_at exist.

segment 3 of 5
Trace the path from IRC receipt to job dispatch via TmiEventSubscriber
Read TmiEventSubscriber at app/Listeners/TmiEventSubscriber.php. The handleMessageEvent method (line 41) validates the MessageEvent has user and message, then dispatches ConsumeTwitchMessageJob::dispatch($event) — one job per message (no batching). The full MessageEvent object is passed to the job constructor. The tmi-sent-ts tag is available on the MessageEvent but is not read or passed along at this stage; it's only extracted later inside the job's failure logging.
outcome
Messages are dispatched individually per message via ConsumeTwitchMessageJob::dispatch($event). The tmi-sent-ts tag is not extracted or forwarded at the subscriber level.

Check for batch/bulk insertion of chat messages
Searched the codebase for any batching, chunking, or bulk insert patterns related to chat_messages. The ConsumeTwitchMessageJob creates and saves one ChatMessage model per job instance. No bulk insert, chunk, or batch logic was found in the job, subscriber, or any related service. Messages are inserted one-at-a-time.
outcome
Chat messages are inserted one-at-a-time, one per job dispatch. No batching or bulk insertion exists.

segment 5 of 5
Identify Horizon queue configuration for chat-processing jobs
Read config/horizon.php. The environments section defines supervisors for 'local', 'staging', and 'production' environments. The 'chat' queue is referenced in supervisor configurations with process counts (e.g., minProcesses=1, maxProcesses=3 in production). The queue name 'chat' is used consistently across environments. Balance strategy is 'simple' where specified.
outcome
Chat messages are processed on the 'chat' Horizon queue with supervisor configurations varying by environment (e.g., 1-3 processes in production, simple balance strategy).
