Security Boundaries

GHW’s security model rests on one principle: the LLM may propose, but it must never apply changes beyond its authority.

Core Boundaries

BoundaryMechanism
Code generationSelfEvolutionGuard + CompileVerifier
Rule adoptionSelfEncoder.verify
Product changesConsent + Audit
ProductIntentManaged by humans/ops; GHW cannot write to it directly
API keysEnvironment variables; never written into source code
State recoveryJSON block parsing; missing blocks are not an error

LLM Red Lines

LLM output cannot bypass:

  • The dangerous-construct blacklist.
  • The file-path whitelist.
  • The existence formula (E) axioms.
  • ProductIntent.
  • Consent.

Constructs such as @panic, unreachable, kernel modifications, and harm to humans are rejected.

Product Change Red Lines

When integrating into production, the following must be preserved:

  • Non-minor changes go through approval.
  • Both apply and rollback write an audit entry.
  • The product runtime’s audit is synced to an external audit system.
  • ProductIntent is updated by humans or through a controlled configuration process.

HTTP API

The built-in HTTP server is suitable for local and intranet debugging. For production:

  • Add reverse-proxy authentication.
  • Restrict the write endpoints under /api/product/*.
  • Apply rate limiting to POST /api/chat and POST /api/tasks.
  • Do not expose state and memory to the public internet.

State Files

state and SQLite may contain:

  • Self-narrative.
  • Business context.
  • Human feedback.
  • Product change audit records.

Recommended permissions:

chmod 700 /var/lib/ghw
chmod 600 /var/lib/ghw/state.json

Upcoming Security Work

  • ProductIntent signature verification.
  • Audit hash chain.
  • Role-based permission model.
  • ProductAdapter idempotency and rollback verification.
  • Multi-tenant data isolation.
