pi-mega-compact@0.4.18

Layered, local, vector-backed context compressor for pi — supersede/collapse/cluster compaction with deduped inline recall.

AI Security Review

scanned 22h ago · by lpm-firewall-ai

No confirmed malicious attack surface is established. The package registers a first-party compaction extension, persists its own state, and optionally starts a loopback dashboard after an explicit command.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

Extension runtime; dashboard process only after the user invokes `mega-dashboard`.

Impact

No install-time execution, remote endpoint, or unconsented AI-agent control-surface write was found.

Mechanism

Local context compaction, state persistence, and optional loopback dashboard/local-model clients.

Rationale

Static inspection shows the scanner signals map to explicit local dashboard, SQLite persistence, and opt-in localhost model integrations. The package contains no concrete malicious chain or lifecycle-based foreign control-surface mutation.

Decision evidence

public snapshot

AI called this Clean at 98.0% confidence as Benign with low false-positive risk.

Evidence for block

Optional `mega-dashboard` explicitly spawns a detached local dashboard process.
Local-model paths pass conversation text to loopback-only configured services.

Evidence against

`package.json` has only `prepublishOnly`; no install/preinstall/postinstall hook.
`src/httpEmbedder.ts` rejects non-loopback embedding URLs.
`src/dedup/raptor/summarizer.ts` rejects non-loopback Ollama URLs.
`extensions/mega-dashboard-cmds.ts` starts only from registered user commands.
No source evidence of credential harvesting, remote exfiltration, or foreign agent-config mutation.
