evidence-ledger skillA
evidence-ledger is agent-read markdown (skill) from synaptiai/synapti-marketplace: Record every material claim as a row in `00-control/evidence-ledger.md` carrying a source-authority level and a claim state (verified, corroborated, reported, inferred, unknown, not applicable), and keep observed, interpreted, unknown, and recommended content in visibly separate blocks. Use when inventorying sources, when drafting any sentence that asserts a fact, or when a verification pass asks what backs a claim. This skill MUST be consulted because an assertion without an `[EV-####]` citatio.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add synaptiai/synapti-marketplace/evidence-ledger@git:20260729.8b433a4mdr add synaptiai/synapti-marketplace/evidence-ledger@sha256:5779ed855a521bd3Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
