The change is mechanical — no behavior, no public strings, no symbol names are modified. It is one of several i18n tickets (#2, #3, #4, #5, #6, #7); this spec covers ticket #7 only. + +## Boundary Context +- **In scope**: Translation of Chinese-language characters that appear in Python docstrings (module/class/function) and inline `#` comments under `backend/`. Removal of comments that merely restate the code. Preservation of `TODO:` / `FIXME:` markers and embedded ticket references. +- **Out of scope**: Chinese characters inside string literals (prompt templates, `logger.{info,warning,error}` arguments, API response bodies, error messages returned to clients) — these are tracked separately by issues #2/#3/#4/#5/#6. No refactoring, reformatting, renaming, or behavior changes. +- **Adjacent expectations**: Spec `i18n-externalize-backend-logs` (issue #6) and the prompt-translation specs handle string-literal Chinese; this spec must leave those untouched so the other tickets remain mergeable. + +## Requirements + +### Requirement 1: Translation Coverage of In-Scope Files +**Objective:** As a maintainer, I want every Chinese docstring and inline comment in the in-scope backend files translated to English, so that I can read and review the code without translation tools. + +#### Acceptance Criteria +1. The Backend Codebase shall contain no Chinese characters (Unicode range U+4E00–U+9FFF) inside Python docstrings under `backend/app/__init__.py`, `backend/app/config.py`, `backend/app/models/`, `backend/app/services/`, `backend/app/api/`, `backend/app/utils/`, `backend/run.py`, and `backend/scripts/`. +2. The Backend Codebase shall contain no Chinese characters inside Python `#` inline comments under the same paths. +3. When `grep -rln '[一-鿿]' backend/ --include='*.py'` is run after this change, the Backend Codebase shall return only files whose remaining Chinese is contained within string literals owned by issues #2/#3/#4/#5/#6. +4. When a docstring is translated, the Translator shall preserve Google-style docstring shape (`Args:`, `Returns:`, `Raises:`, `Yields:` sections) per `dev-guidelines.md`. + +### Requirement 2: Preservation of Code Behavior +**Objective:** As a maintainer, I want the translation to be comments-and-docstrings-only, so that runtime behavior is provably unchanged. + +#### Acceptance Criteria +1. The Translator shall not modify any executable Python statement (assignments, function calls, control flow, decorators, imports). +2. The Translator shall not modify any Python string literal (single-, double-, triple-quoted, f-string, raw, byte) regardless of whether it contains Chinese characters. +3. The Translator shall not rename any symbol (variable, function, class, module, parameter). +4. When `uv run python -m pytest backend/scripts/test_profile_format.py` is run after the change, the Backend Codebase shall exit with status 0. +5. If a diff line touches any non-comment, non-docstring code, the Translator shall reject that diff hunk and revise. + +### Requirement 3: Comment Quality Hygiene +**Objective:** As a maintainer, I want translated comments to add value, so that the codebase remains easy to read after the migration. + +#### Acceptance Criteria +1. When a Chinese comment merely restates the immediately following code (e.g. `# 初始化客户端` above `client = Client()`), the Translator shall delete the comment rather than translate it. +2. When a Chinese comment captures non-obvious *why* (constraints, workarounds, invariants), the Translator shall translate it to a faithful English equivalent. +3. The Translator shall preserve any `TODO:` / `FIXME:` marker and any embedded ticket reference (e.g. `#1234`, `PROJ-456`) verbatim within the translated comment. +4. The Translator shall not introduce new comments that did not exist (or had no Chinese equivalent) in the original source. + +### Requirement 4: Style and Format Compliance +**Objective:** As a maintainer, I want the translated output to comply with project style rules, so that no follow-up cleanup PR is needed. + +#### Acceptance Criteria +1. The Translator shall keep all translated docstrings and comments at or below 120 characters per line. +2. The Translator shall not introduce trailing whitespace on any line. +3. The Translator shall preserve the original indentation (tabs/spaces) of every comment and docstring. +4. The Translator shall use double quotes for any docstring it rewrites, matching the existing Python convention in the file. +5. Where a file already uses 4-space indentation, the Translator shall preserve that indentation. + +### Requirement 5: Discovery and Verification Workflow +**Objective:** As a reviewer, I want a reproducible discovery and verification workflow, so that I can confirm coverage and absence of regressions in CI or locally. + +#### Acceptance Criteria +1. The Translator shall enumerate candidate files using `grep -rln '[一-鿿]' backend/ --include='*.py'` before beginning work. +2. The Translator shall re-run the same `grep` after each batch and confirm the residual hits are limited to string-literal Chinese owned by adjacent tickets (#2/#3/#4/#5/#6). +3. When the residual `grep` hits include any non-string-literal Chinese, the Translator shall classify those hits as in-scope and continue translation until they are gone. +4. The Translator shall verify that `git diff --stat` only reports changes inside the in-scope file paths listed in Requirement 1. + +### Requirement 6: Tracking and Branching +**Objective:** As a release manager, I want the work tracked against ticket #7 on a dedicated branch, so that the PR remains scoped and traceable. + +#### Acceptance Criteria +1. The Translator shall produce changes on a branch named `docs/i18n-7-translate-backend-comments`. +2. The Translator shall reference issue `salestech-group/MiroFish#7` in commit messages or PR description. +3. When committing, the Translator shall use Conventional Commits with type `docs` and scope `i18n` (e.g. `docs(i18n): translate chinese docstrings/comments in backend/`). +4. The Translator shall not include unrelated changes (e.g. dependency bumps, config changes, refactors) in the resulting PR. diff --git a/.kiro/specs/i18n-translate-backend-comments/research.md b/.kiro/specs/i18n-translate-backend-comments/research.md new file mode 100644 index 00000000..c9d9ad4e --- /dev/null +++ b/.kiro/specs/i18n-translate-backend-comments/research.md @@ -0,0 +1,80 @@ +# Research & Design Decisions — `i18n-translate-backend-comments` + +## Summary +- **Feature**: `i18n-translate-backend-comments` +- **Discovery Scope**: Simple Addition (mechanical translation, no architectural change) +- **Key Findings**: + - 37 in-scope `backend/` Python files contain Chinese characters in docstrings or `#` comments.
