sancio-harness 1.2.0

Sancio Harness (SH) — Sancio runtime substrate adapter for AI King ecosystem (MIT)

sancio-harness

Sancio substrate adapter for AI King — bridges AI King's engine to the Sancio runtime that targets breaking past the Claude Code L1/L8/L6 platform ceiling.

Install

pip install "aiking[sh]"
# or directly:
pip install sancio-harness

What this adapter does

Sancio runs as a long-lived agent gateway (canonical deploy at sancio.ai-king.dev). It implements two enforcement channels Claude Code's SDK does not expose:

1. Observation-channel deny — rewrite is_error=True payloads so the LLM sees deny verdicts as tool errors rather than silently accepted side effects.
2. Cross-iteration policy mutation — escalate policy changes between turns instead of only within a single PostToolUse window.

sancio-harness is the AI King engine bridge for that runtime — wires the engine's guards / hooks / ZIQ / FEATURE_META into Sancio's two enforcement channels. The Sancio runtime binary itself ships through the separate sancio distribution.

MIT. The Sancio runtime is also MIT; the AI King engine (aiking-core) underneath remains AGPL.
