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 proof-only stdio MCP server through .mcp.json: narrative_ledger_inspect_inline, narrative_ledger_verify_inline, and narrative_ledger_query_inline. MCP accepts bounded inline manifest/event strings only, never paths, and performs no filesystem, network, process, or artifact writes. Because canon source bytes are not supplied, inline verification reports verified-structure plus sourceBytesVerified: false; only DSH/CLI filesystem verification may report the canon sources as fully verified.

Version 0.2.0 uses a host-neutral namespace entry with no private DSH runtime dependency or default export, so the stock Cordis Web loader can compose it safely. DSH and CLI remain the explicit filesystem surfaces; their content-addressed artifact response includes byte length and successful read-back verification.

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.
