DSH Config Origin Proof

An evidence layer for DeepSeek Harness configuration source ownership. It verifies an explicit redacted recording of precedence domains, source observations, the expected winning source and value digest, shadowed sources, and unobserved higher-priority gaps.

It does not reimplement the DSH composer, collect live configuration, or compare policy changes. DSH's own --dump-config remains the authority for composition. This plugin turns a structured recording from that or another trusted producer into a reproducible receipt. dsh-policy-drift-proof compares baseline and observed policy posture; dsh-profile-lock-proof proves installed bundle closure; this project answers which recorded source won and why.

Raw values and secret-, credential-, prompt-, message- or prose-shaped fields are rejected. Reports contain only stable IDs, SHA-256 digests and verdicts. The verifier fails closed when a higher-priority source is unobserved.

Surfaces

• DSH: dsh_config_origin_inspect, dsh_config_origin_verify.
• CLI: dsh-config-origin-proof verify --workspace-root examples --recording recording.json --artifact-dir artifacts.
• MCP: config_origin_inspect_inline, config_origin_verify_inline; inline-only, no filesystem, network, process or artifact writes.

The ordering in examples/recording.json follows DSH's published configuration-source ownership contract, but the recording is explicit and revision-bound so a future DSH change cannot silently rewrite old evidence.
