DSH Narrative Ledger

A read-only, verifiable story-state ledger for DeepSeek Harness. It is not a novel generator or writing-prompt wrapper. Existing tools such as Novel Director and InkOS manage writing workflows and rich story state; this plugin is the complementary evidence layer for machine-checkable continuity.

What it verifies

• content-addressed external canon sources without copying manuscript prose into reports;

• contiguous immutable event sequence and monotonic story time;

• explicit fact assertion and retraction with resolvable subject, predicate, value and source IDs;

• single-value contradictions such as two simultaneous locations or mutually exclusive states;

• character knowledge acquired only by witnessing an assertion or participating in a scene that communicates an active fact;

• spoiler-safe projection at a sequence number, returning only fact IDs and knowledge IDs;

• stale/missing canon, inactive fact communication and invalid retraction disclosure;

• deterministic content-addressed JSON reports with atomic publication and SHA-256 read-back.

The ledger rejects prose-, chapter-, draft-, prompt- and secret-shaped fields. Paths must remain inside workspaceRoot; symlinks are rejected. It runs no shell and makes no network requests. Only an explicit artifactDir may be written.

Install

dsh plugin --profile web add github:dongsheng123132/dsh-narrative-ledger

DSH tools: dsh_narrative_ledger_inspect, dsh_narrative_ledger_verify, dsh_narrative_ledger_query.

The Codex plugin also exposes a stdio MCP server with the equivalent narrative_ledger_* tools through .mcp.json.

CLI

dsh-narrative-ledger verify --workspace-root examples/basic --manifest narrative.manifest.json --events events.jsonl --artifact-dir artifacts
dsh-narrative-ledger query --workspace-root examples/basic --manifest narrative.manifest.json --events events.jsonl --through-seq 2

See examples/basic: Bob does not know the key-location fact at sequence 2 and learns it only in the disclosure scene at sequence 3.
