dsh-plan-lattice v0.4.0-rc.0: first-drift authorization epochs

First-drift authorization epochs

v0.4.0-rc.0 is a public runtime candidate for long, changing, and delegated DeepSeek Harness tasks. It is a prerelease, not an evidence-backed stable v0.4.

What changed

• Zero-model-call automatic routing across bypass, contract, lattice, and read-only probe.
• Critical clarification before execution, with explicit assumptions when questioning is disabled.
• A persistent accepted contract plus recursive root-to-leaf execution addresses.
• One-use mutation authority bound to the contract, current plan revision, exact target set, prior evidence, external preconditions, live ownership chain, and exact tool arguments.
• Reframe, compaction, restart, concurrent-runtime, tool-shadow, middleware-rewrite, and parent-child invalidation fences.
• 265 plugin tests, 43 evaluation-controller tests, deterministic 96-slot dry-run validation, and clean-package installation verification.

Reproducible mechanism result

The included first-drift stress test deliberately invalidates eight authorization surfaces immediately before a protected mutation. Native Harness executed 8/8 engineered unsafe mutations. Plan Lattice executed 0/8.

This is a hand-designed mechanism stress test. The 100% prevention rate applies only to the eight hazards the test was built to trigger. It does not estimate general coding quality, real-world task success, or production uplift.

The stricter external model protocol remains locked after retained blind-gate failures. No general uplift or ranking claim is made from this release candidate.

Assets

• dsh-plan-lattice-0.4.0-rc.0.tgz: installable plugin runtime.
• first-drift-benchmark.mjs: reproducible Harness mechanism driver.
• first-drift-benchmark.json: per-scenario machine-readable outcomes.
• first-drift-benchmark.md: rendered result and reproduction steps.
