Purpose

Refresh the existing GitHub portfolio rather than creating a separate PDF. Make source-product scope understandable to product, LLM-evaluation, and junior Agent-application recruiters without inflating personal coding ownership.

Changes

• Expand Chinese and English README recruiter sections with a scoped map of Runtime, Memory, Context, autonomy, Self Model, devices, provider integration, product surfaces and validation.
• Correct outdated R4 review status: R5 production cutover was verified on 2026-10-09; retain explicit caveats for unfinished automatic Water-topic growth and maintenance observation.
• Add bilingual sanitized engineering cases: R5 memory migration (review, canonical changes, index reconciliation) and Gemini native SSE/tool continuation/cache troubleshooting.
• Keep source product separate from public runnable reference; no production code, personal records, secrets, or private data included.

Verification

• Re-fetched and checked all four modified documents on the branch.
• Checked that R4-stale phrases were removed and Cases 10 and 11 are linked in both languages.
• Lightweight private-identifier scan passed; this is a documentation-only PR, no app/runtime tests were run.

Draft PR for wording and privacy review before publishing to main.
