docs(onboarding): link new audit / design / eval docs from

the root README + AGENTS.md

Without this, the four docs added on this branch
(AUDIT_AND_ROADMAP, INDEX, BLOCK_LEVEL_EVICTION_DESIGN,
D_TO_P_SYNC_CONTRACT, EVALUATION_PROTOCOL) are reachable
only by listing docs/. This wires them into the two entry
points an agent or collaborator hits first.

README.md changes:
  - top-of-page pointer to INDEX_ZH for new collaborators
  - pointer to AUDIT_AND_ROADMAP_ZH for project state
  - "单元测试 (无 GPU)" section: how to run pytest
  - "评测脚本" section: invocations for the two new
    analysis scripts

AGENTS.md changes:
  - top section "For new collaborators / agents" before
    the existing "Environment" block, pointing at INDEX_ZH,
    AUDIT_AND_ROADMAP_ZH, the two ready-to-pick-up design
    docs, and EVALUATION_PROTOCOL_ZH
  - pytest invocation under Environment

 # AGENTS.md
 
+## For new collaborators / agents
+
+Before doing anything else, read [docs/INDEX_ZH.md](docs/INDEX_ZH.md). It points to the
+3 must-read docs and a role-based reading path (new SWE, paper reviewer,
+reproducing student, control-plane reader).
+
+Cross-branch progress, weaknesses, and roadmap live in
+[docs/AUDIT_AND_ROADMAP_ZH.md](docs/AUDIT_AND_ROADMAP_ZH.md). It is the single source of truth
+for "what's done, what's broken, what to do next."
+
+Two engineering work items are pre-specced and ready to pick up:
+- block-level eviction refactor — [docs/BLOCK_LEVEL_EVICTION_DESIGN_ZH.md](docs/BLOCK_LEVEL_EVICTION_DESIGN_ZH.md)
+- D→P incremental KV sync — [docs/D_TO_P_SYNC_CONTRACT_ZH.md](docs/D_TO_P_SYNC_CONTRACT_ZH.md)
+
+Evaluation protocol (paper-quality N, paired CI, stratification,
+baselines) is in [docs/EVALUATION_PROTOCOL_ZH.md](docs/EVALUATION_PROTOCOL_ZH.md).
+
 ## Environment
 
 Use `uv` to manage all python environment. `uv add` to manage deps so that we can `uv sync` to get exactly same runnable environment each time.
 
+Algorithm-layer unit tests (no GPU, no SGLang):
+
+```bash
+uv sync --group test
+uv run pytest
+```
+
 ## Goal
 
 Build a minimal prototype on top of **SGLang xPyD** to test whether **session-aware / KV-cache-aware P/D routing** can improve **end-to-end latency** for agentic coding workloads.
