Show HN: Importguard – Measure and enforce Python import-time behavior in CI

I built a CLI tool to catch slow imports and sneaky side effects before they ship to production.

The problem: Python imports can quietly become a performance trap. Your CLI takes 2 seconds to show --help because importing your package pulls in pandas. Or worse, importing a module makes network calls or writes files as a side effect.

Importguard uses Python's -X importtime flag to measure exactly how long each import takes, then lets you:

- Set time budgets: `importguard check mypkg --max-ms 200` - Ban heavy imports: `importguard check mypkg.cli --ban pandas --ban torch` - Get reliable timing: `--repeat 5` runs multiple times and reports median - Configure per-module rules in `.importguard.toml`

It runs in an isolated subprocess so it doesn't pollute your interpreter, and outputs JSON for CI integration.

Use cases: - Keep CLI startup snappy - Prevent serverless cold start regressions (Lambda/Cloud Functions) - Ensure library hygiene (don't force users to install heavy deps)

pip install importguardpy

Show HN: Neural_covenant – 129-modality AGI stack built for sovereignty

I am a builder, not a researcher. Version 0.6.0 of NEURAL_COVENANT moves beyond standard LLM text prediction into a functional 129-modality AGI implementation.

Repo: https://github.com/AI-Sovereign/Multimodal-AGI-Architecture-...

Key Engineering Specs: * 129-Modality Nexus: Ingests Bio-Physiological (HRV/GSR), Electromagnetic (RF/WiFi), and Semantic data. Handled via Hierarchical Tensor Fusion into a shared latent space Z. * The Neural Trinity: Integrates snntorch (LIF spiking neurons) for event-driven efficiency, torch-geometric (GCN) for relational mapping, and Transformers for high-level cognition. * Performance: Serialized via FlatBuffers and served through a Granian (Rust) backend to maintain sub-millisecond latency. * Mathematical Core: Optimizes for Capacity Φ to maintain intelligence density across streams. Spiking dynamics: U[t+1] = βU[t] + (1-β)I[t] - S[t]U_thresh.

This is a local-first, sovereign architecture. I’m looking for feedback from the community on the normalization efficiency of the 129-modality super-tensor using Polars and the GCN update normalization constants.

Show HN: The Best Way to use MCPs with coding agents

Hey folks, I built Jilebi - an MCP server/runtime written in rust that gets its tools from javascript plugins. These plugins run in a deno sandboxed Runtime and need permissions to access file and network resources.

It simplifies creating and installing MCP servers. Give it a try! Right now I'm working on reducing the size of the executable - any tips would be appreciated.

Happy new year!

Show HN: Forensic evidence of iOS mesh networking bypassing Airplane Mode

I found evidence of autonomous mesh networking on iOS during Airplane Mode. What am I missing?

Did forensic analysis on my iPhone during Airplane Mode isolation. Kernel stats show 2,657 packets transmitted and 84.5MB processed through mDNSResponder while interfaces report "inactive". Found a parallel utun2 tunnel bound to IDS framework that persists during isolation. Applied Shannon-Hartley theorem to verify the channel capacity supports this volume. Either I'm misunderstanding legitimate system behavior, or this is a covert channel. Reproducible steps and raw evidence included.
