[🐛 BUG]: mode: raw ignored for temporal plugin

No duplicates 🥲.

• I have searched for a similar issue in our bug tracker and didn't find any solutions.

What happened?

When using the Temporal plugin, RoadRunner still prefixes every log line with a timestamp, level, and channel — even when encoding: json and mode: raw are configured. This breaks JSON parsing in log processors like Elasticsearch, where the prefixed metadata prevents proper decoding of Laravel’s JSON log content.
As a result, log messages appear as raw strings instead of structured JSON objects, making it impossible to extract or filter context fields correctly.

Version (rr --version)

• RoadRunner version: v2025.1.1
• Temporal plugin: latest
• Temporal PHP SDK: 2.14.1

How to reproduce the issue?

1. Configure .rr.yaml:

logs:
  encoding: json
  level: "${TEMPORAL_LOG_LEVEL:-debug}"
  mode: "${TEMPORAL_LOG_MODE:-production}"
  channels:
    temporal:
      level: info
      mode: raw
    rpc.level: error      # Only RPC errors
    server.level: info    # Worker lifecycle
    app.level: info       # Laravel logs
    lock.level: warn      # Logs RoadRunner lock events

2. Run a Temporal PHP worker (using temporalio/roadrunner-temporal).
3. Trigger a workflow that calls Workflow::getLogger()->info().

Hey @koren88 👋🏻
If you want structured logs, you may use mode: json for the temporal logs as well. I'll not break any JSON parser, since it'd be a valid JSON.
But anyway, I'll double-check that, in raw mode, you should have a raw message from the worker. But in that case - you're responsible for producing a valid JSON. This log will still break JSON parsing:

[2025-10-24 10:35:51] info: Bridge workflow started {"task_queue":"default","activity":"sendNotification","startedAt":"2025-10-24 10:35:51"}

Thanks @rustatian — makes sense.

Just to clarify what we’re trying to achieve: we don’t need RR to validate or format JSON, we only need mode: raw to pass through the message exactly as produced by the worker — without the timestamp, level, or channel prefix.

Our worker already emits valid JSON — for example:
{"message":"Workflow started","context":{"activity":"sendNotification"}}

But currently, it’s still prefixed like this:
2025-10-24T10:35:51+0000 INFO server {"message":"Workflow started","context":{"activity":"sendNotification"}}
That prefix breaks structured ingestion in Elasticsearch, because the parser expects the line to start with {.
If mode: raw just streamed the payload untouched, that would solve the problem completely.

Would this config behave that way once the change is applied?

logs:
  encoding: json
  level: "${TEMPORAL_LOG_LEVEL:-debug}"
  mode: "${TEMPORAL_LOG_MODE:-production}"
  channels:
    temporal:
      level: info
      mode: raw

Yep, this looks like a bug. That info should not be included with raw log. I'll check that.
