AI Security Review
scanned 2d ago · by lpm-firewall-aiThe manifest has no install lifecycle hooks, and the flagged persistence and agent-configuration mutations are invoked through dedicated user commands. The credential-to-foreign-host hint is a false positive: the OpenAI URL is used to read a JWT claim locally, while the proof is sent to the configured Agnoclast service as part of the confidential-brain feature.
Static reason
No blocking static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
Closeout persistence requires running closeout-install; channel edits require selecting a channel.
Impact
No malicious behavior found in the reviewed paths; explicitly enabled closeout may resume eligible quiet sessions using the user's Claude account.
Mechanism
The package provides MCP integration and optional background session closeout. The flagged OpenAI host string is used to identify a JWT claim while parsing locally.
AI rationale
The manifest has no install lifecycle hooks, and the flagged persistence and agent-configuration mutations are invoked through dedicated user commands. The credential-to-foreign-host hint is a false positive: the OpenAI URL is used to read a JWT claim locally, while the proof is sent to the configured Agnoclast service as part of the confidential-brain feature.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest has no install, preinstall, or postinstall hook; its scripts are release, promote, and rollback commands.
- Background closeout is described as off by default and is installed by the explicit closeout-install command.
- The closeout job reviews quiet sessions with limits and runs using the user's Claude account.
- Channel configuration edits are part of the explicit channel command; with no argument, it reports status.
- The OpenAI URL appears as a JWT claim namespace parsed locally; the proof is sent to the configured Agnoclast service for a confidential-brain seat.
