The Slack Block Kit payload dump and the nested-attachment text budget are both fed to the agent, and trajectory_compressor's summarizer input becomes training data; all three still used the imitable bare "... [truncated]" idiom. Route them through elide()/elide_middle() with module-level imports and extend the no-idiom invariant to scan plugins/platforms/slack and trajectory_compressor.py.

# un-acked 404s pushes Slack's failure rate past its 95%/60-min threshold and Slack auto-disables
|
||
# the app's Event Subscriptions — silently killing ALL inbound delivery until manually re-enabled.
|
||
# 2. Noise: each unhandled envelope also logs a slack_bolt "Unhandled request" WARNING, flooding
|
||
# gateway logs in busy channels. Registered AFTER every named handler: bolt dispatches to the first
|
||
# matching listener, so the named handlers above always win and this only fires for truly unhandled
|
||
# types. The envelope is acked with 200, keeping the failure rate near 0% regardless of which events
