AURA Harness — a runtime coat for agent loops: audit, policy, and compliance export.

v0.3.5 packages everything merged since v0.3.4. The headline is operational conformance on the spine: spectrum-level egress bind, goal drift and schedule SLO observer presets, and audit-report findings for declared intent vs observed behavior. This release also ships verified operator identity, hardened session export invariants, a public integrations index with an Ollama body loop, and a full documentation sweep.

Experimental (alpha). API may change before 1.0.

Install

pip install aura-harness==0.3.5 # or simply pip instal aura-harness

Optional Skillware integration:

pip install "aura-harness[skillware]==0.3.5"

From source:

git clone https://github.com/ARPAHLS/aura.git
cd aura
git checkout v0.3.5
pip install -e ".[dev]"

Spectrum & operational conformance

  • Spectrum enforcement (#27) — spectrum.level injects egress rules at session open (low / mid / high / full); sequencer_required at full bind; aura agent set --spectrum-level; effective_spectrum on agent show
  • Goal drift observer (#46) — preset: goal_drift emits conformance.drift when tool intents diverge from profile goal / forbidden topics
  • Schedule SLO observer (#46) — preset: schedule_slo emits slo.missed when required work misses deadline + grace; audit findings GOAL_DRIFT / SCHEDULE_SLO_MISS
  • Host stress simulation — scripts/aura_host_stress_sim.py (16 coat/spectrum scenarios)
  • Coat flow report — scripts/aura_coat_flow_report.py structured session breakdown per spectrum level

Identity & session hardening

  • Verified operator identity (#55) — optional identity adapters (manual, mock, OIDC, Auth0); identity.bound; ids.operator on spine trailers; export redaction; aura identity show
  • Session lifecycle invariants (#15) — strict closed-session errors; atomic summary + OTel export; frozen open snapshot; in-memory audit report when export=False

Integrations & examples

  • Integrations layout (#19) — top-level integrations/README.md; Skillware mock/live entrypoints; LangGraph stub
  • Ollama body loop (#20) — stdlib HTTP loop under integrations/ollama/
  • Audit pipeline example (#23) — two sessions, compare, hash-chain verify, OTel assert, CLI follow-ups
  • Examples 10–11 — tailored metrics snapshot; goal drift + schedule SLO demo
  • Skillware 0.5.4 sync — optional extra skillware>=0.5.4,<0.6

Docs & comparison

  • Documentation sweep (#14) — INDEX three-tier entry; refreshed architecture, concepts, field-services
  • docs/comparison.md refresh (#39) — loose / tight / tailored coat framing; shipped scope through v0.3.5
  • 140 tests — incl. goal/SLO observers, spectrum enforcement, audit pipeline OTel, example smoke
