` English tagline).
+- **Rationale**: Preserves the existing visual treatment (italic subtitle below the Trendshift badge). Avoids style drift on a docs-only PR.
+- **Trade-offs**: Slightly different visual weight (italic only) vs. the prior bilingual stack (plain Chinese + italic English). Acceptable for an English-facing doc.
+- **Follow-up**: None.
+
+### Decision: Use `git mv` for all renames
+
+- **Context**: Need to preserve rename detection.
+- **Alternatives Considered**: `git mv` vs. shell `mv` + `git rm` / `git add`.
+- **Selected Approach**: `git mv "old" "new"` with quoted paths.
+- **Rationale**: Unambiguous record in the index; matches existing project practice.
+- **Trade-offs**: None.
+- **Follow-up**: None.
+
+## Risks & Mitigations
+
+- **Risk:** Broken images on rendered GitHub README after merge. **Mitigation:** Post-edit grep to confirm zero remaining Chinese-named asset references in any README; preview rendered markdown locally or on a branch before merge.
+- **Risk:** Off-repo deep links to old asset URLs (Trendshift cards, social previews). **Mitigation:** Accepted; cost is a single missing image on an external page.
+- **Risk:** Diff churn from accidentally re-encoding a binary on macOS or Windows checkout. **Mitigation:** Use `git mv` (no content transform); verify `git diff --stat` shows only renames for the asset files (no content delta).

+# Implementation Plan
+
+- [x] 1. Translate Chinese taglines to English in the project's English-facing metadata
+ - In `README.md`, delete the Chinese tagline line and the immediately following `` line so the existing italic English subtitle on the next line stands as the lone tagline; verify the result still renders with one tagline visible above the Shanda badge
+ - Apply the identical edit to `README-EN.md`
+ - In `package.json`, set the `description` value to `MiroFish - A Simple and Universal Swarm Intelligence Engine, Predicting Anything`
+ - In `backend/pyproject.toml`, set the `description` value to the same English string used in `package.json`
+ - Leave `README-ZH.md` line 7 (the Chinese tagline) untouched
+ - Observable completion: a ripgrep scan for `[\x{4e00}-\x{9fff}]` over `README.md`, `README-EN.md`, `package.json`, and `backend/pyproject.toml` returns hits **only** on the language-switcher line of the two READMEs
+ - _Requirements: 1.1, 1.2, 1.3, 1.4, 1.5_
+
+- [x] 2. (P) Rename Chinese-named static image assets to ASCII filenames using git mv
+ - Move the six screenshot files `static/image/Screenshot/运行截图{1..6}.png` to `static/image/Screenshot/screenshot{1..6}.png`
+ - Move `static/image/武大模拟演示封面.png` to `static/image/wuhan-university-simulation-cover.png`
+ - Move `static/image/红楼梦模拟推演封面.jpg` to `static/image/dream-of-the-red-chamber-simulation-cover.jpg`
+ - Move `static/image/QQ群.png` to `static/image/qq-group.png`
+ - Quote source paths in shell invocations because they contain non-ASCII characters
+ - Use `git mv` (not shell `mv` + `git add`) so rename detection is recorded directly in the index
+ - Observable completion: `git status` reports nine `renamed:` entries with no other file modifications; `git diff --stat -M` shows zero content-line delta for each asset
+ - _Requirements: 2.1, 2.2, 2.3, 2.4, 2.5, 2.6_
+ - _Boundary: static/image/_
+
+- [x] 3. Update README image references to point at the renamed ASCII asset paths
+ - In `README.md`, rewrite the nine `
` paths on lines 52–61, 71, 79, and 220 so each points at the corresponding ASCII filename from task 2
+ - Apply the identical nine edits to `README-EN.md`
+ - Apply the identical nine edits to `README-ZH.md` (asset path updates only — Chinese body text and Chinese alt attributes preserved)
+ - Observable completion: a ripgrep search for `运行截图|武大模拟演示封面|红楼梦模拟推演封面|QQ群` in `README.md`, `README-EN.md`, and `README-ZH.md` returns zero matches
+ - _Requirements: 3.1, 3.2, 3.3_
+ - _Depends: 2_
+
+- [x] 4. Verify acceptance gates before commit
+- [x] 4.1 Run the Chinese-character verification scan and confirm zero residual hits in the EN READMEs body
+ - Execute `rg --pcre2 '[\x{4e00}-\x{9fff}]' README.md README-EN.md | rg -v 'README-ZH\.md'` from the repo root
+ - Observable completion: the pipeline produces zero output lines, confirming the only Chinese characters left in the EN READMEs are inside the language-switcher link to `README-ZH.md`
+ - _Requirements: 4.1, 4.2, 4.3_
+
+- [x] 4.2 Confirm asset renames are byte-preserving and unambiguous
+ - Run `git diff --stat -M` and verify each of the nine asset files appears as a pure rename (no `+` or `-` line counts)
+ - Run `git status` and confirm there are no untracked Chinese-named files left behind in `static/image/` or `static/image/Screenshot/`
+ - Observable completion: nine `renamed:` entries in `git status`; zero untracked Chinese-named asset files; zero content delta on the asset rows of `git diff --stat`
+ - _Requirements: 2.5, 2.6, 3.4_
+
+- [x] 4.3 Confirm rendered images by spot-checking the README in a Markdown previewer
+ - Open `README.md`, `README-EN.md`, and `README-ZH.md` in a Markdown preview (GitHub preview on the feature branch or local previewer) and inspect the screenshot grid, the two video-cover thumbnails, and the QQ group image on each file
+ - Observable completion: every `![]()
` element renders an actual image (no broken-image placeholder) on all three READMEs
+ - _Requirements: 3.4_
+ - **Note**: This task ran in an autonomous environment where no Markdown previewer was available; instead, every `![]()
` path in all three READMEs was cross-checked against the working tree and all 33 references resolved to existing files (zero broken paths). A reviewer should still spot-check on the GitHub-rendered PR preview.
