World Model MCP

Enforcement, provenance, and harness-neutral memory for AI coding agents. A temporal knowledge graph that validates code changes against learned constraints at the edit boundary, re-injects relevant context after compaction, tracks contradictions with confidence-weighted resolution, and runs across Claude Code, Cursor, Codex, pi, OpenClaw, Hermes Agent, and Continue.

Status: v0.10.0 — 27 MCP tools, 22 CLI subcommands, 417 tests, SWE-bench Verified repeat-mistake benchmark with a pre-registered methodology and a multi-seed replication appendix. v0.10.0 extends the harness-neutral memory story from four runtimes (Claude Code + Cursor + Codex + pi) to seven with three new adapters shipping in one release: OpenClaw (install-openclaw), Hermes Agent (install-hermes), and Continue (install-continue). Each is verified end-to-end against the live runtime where possible: OpenClaw 2026.6.11 reports 27 tools via openclaw mcp probe world-model; Hermes v0.17.0 reports 27 tools via hermes mcp test world-model while preserving all 1327 lines of the reference config.yaml including every documentation comment (regression-tested); Continue's exact stdio spawn returns 27 tools via a live tools/list roundtrip. Runtimes with no native memory layer (OpenClaw, Continue) get world-model-mcp as pure additive integration; Hermes' bounded manual-curation memory (MEMORY.md + USER.md, character-capped, no auto-decay per Hermes docs) is complemented additively by world-model-mcp's per-fact provenance and per-evidence-type decay. v0.9.2 shipped the multi-seed replication appendix per pre-registered SEED_PLAN.md: on the 17-instance subset, load-bearing replication count is 0 of 7, mean paired delta across two seeds is +0.24 per instance with bootstrap 95 percent CI [0.00, 0.47]. The v0.9 +10.2 pts headline reads as a single-trial upper bound; the wedge claims (lifecycle-hook capture, per-fact provenance, per-evidence-type decay, PreToolUse defer) survive the multi-seed update because they are architectural, not empirical. Full appendix and per-instance results in benchmarks/repeat-mistake/RESULTS.md. v0.9.1 restored the embedded telemetry token after a release-mechanics miss in v0.9.0. v0.9.0 shipped the empirical wedge proof. v0.8.1 expanded the contradiction-resolution benchmark to 105 pairs across 19 categories. v0.8.0 added domain-aware confidence decay with per-evidence-type TTL, per-item provenance fields source_tool and confirmer, slash command write operations, and a confirmer parameter on resolve_contradiction. Antigravity adapter held pending a TransformCompactionHook in the SDK. v0.7.6 added the /world-model slash command and status-watch TUI widget. v0.7.5 added the Codex CLI adapter. v0.7.0 introduced PostCompact auto-injection, the defer enforcement tier, confidence-weighted contradiction resolution, and a compaction audit log. Contributions welcome.
