dsh v0.3.3 — QUANT seam in core + ULTRA-LSP

Highlights

QUANT — low-bit quantization foundation in core

• @deepseek-ai/dsh-quant: ctx.quant capability seam — provider registry by branded backend id, order-independent selection, quantize / gemm / capabilities closed-union vocabulary aligned to entheai crates/ternary semantics.
• @deepseek-ai/dsh-quant-reference: pure-software provider (group symmetric ternary, maxOutputBytes bound), mounted in dsh-base with the seam — zero model-visible surface.
• @deepseek-ai/dsh-tool-quant: opt-in quant_ternary tool; stays out of core defaults until a hardware backend passes the audit-checklist evidence gate (8× vs FP16, PPL ≤ +0.05, >350 GB/s).

ULTRA-LSP — language-server code intelligence in core (from 0.3.2)

• lsp / lsp-stdio / tool-lsp mounted in the dsh-base core bundle with a TypeScript/JavaScript stdio provider.

Benchmark harness as a first-class gate (from 0.3.2)

• pnpm bench:entheai (full sweep) + pnpm bench:entheai:verify (keyless gate); canonical is_pure_syntax module; SWEEP_TRIAL_TIMEOUT_S.
• Verified 100% pass across all five AST/logic benchmark tasks.

Verification

• 26/26 quant package tests; host tsc clean; invariants 238 conform; verify-cordis-config 125 pass; headless core boot with quant mounted exits 0.
