Provenance policy

SYSTEM ERROR'S THE LOOP is a clean-room public skill pack. Its architecture was informed by System Error's operational experience, but internal source files are not used as a shipping source tree.

Every skill and protocol passes these gates before shipping:

1. Trace its local history and record a content checksum.
2. Compare its purpose and text against known upstream sources.
3. Establish a compatible licence for every included file.
4. Audit for private paths, people, credentials, infrastructure, customers, incidents and vertical intelligence.
5. Write a clean, harness-neutral System Error implementation when reuse is not proven safe.
6. Test installation, discovery, invocation declarations, safety invariants and failure reporting across Codex, Claude Code, Kimi Code, OpenCode and DeepSeek Harness; record provider-backed probes separately.
7. Obtain an independent final review.

Classification

• system-error-original: new System Error work designed and written for this public repository without a predecessor artifact.
• system-error-rewrite: new public System Error work that implements a capability previously present in a private System Error predecessor, without copying that private artifact.
• upstream-dependency: detected and invoked from its maintained upstream source; never vendored here.
• excluded: not shipped because provenance, licence or privacy requirements are not satisfied.

Both system-error-original and system-error-rewrite are System Error-authored public work. The distinction records lineage and the clean-public-boundary method; it does not mean that a rewrite is third-party work, has weaker ownership, or is a lightly reworded copy. Where the predecessor's original authorship or licence cannot be proven, that predecessor remains excluded even if a separate public fallback is later written.

Rewording does not remove licence obligations. A missing licence is a failed reuse gate, not permission to copy.

Current decision

No audited internal skill or helper is approved for verbatim inclusion. All 31 public packages ship in v0.1: 9 are system-error-original, 21 are clean system-error-rewrite implementations of capabilities with System Error predecessors, and 1 is an upstream-dependency orchestration wrapper. The classification records lineage, not quality, ownership or usability. The exact package and checksum set is recorded in docs/provenance/v0.1-shipping-manifest.md and docs/provenance/skill-records.md.

Every package is a complete harness-native instruction surface. The Python toolkit adds deterministic installation, diagnosis, state, lease, authority and conformance automation; it is additive implementation depth around the skills. Five first-class adapters ship for Codex, Claude Code, Kimi Code, OpenCode and DeepSeek Harness.

Original System Error work created for this repository is licensed under MIT. That repository licence does not change the rights or reuse status of audited private, vendor or community artifacts.

Evidence handling

The public record uses redacted source labels, commit identifiers and SHA-256 checksums. Private paths, repository URLs, incident details and infrastructure identifiers stay in the private audit record.
