data/Index of the Project Gutenberg Works of Lucius Annaeus Seneca by Lucius Annaeus Seneca.txt (1)

1-1: 파일 시작 BOM 문자 제거 권장

Line 1에 UTF-8 BOM(보이지 않는 문자)이 포함되어 있습니다. 인덱싱/청킹/문자열 매칭에서 미세한 불일치를 만들 수 있으니 BOM 없는 UTF-8로 저장해 주세요.

data/Euthyphro by Plato.txt (1)

1-1508: 데이터 파일 추가가 적절합니다.

이 파일은 Project Gutenberg의 공개 도메인 eBook으로, RAG 시스템의 철학적 텍스트 데이터로 사용하기에 적합합니다. 파일에는 적절한 라이선스 정보와 출처가 포함되어 있습니다.

참고: 파일 시작 부분에 UTF-8 BOM(Byte Order Mark, )이 포함되어 있습니다. 일부 텍스트 처리 도구에서는 BOM이 문제를 일으킬 수 있으므로, 임베딩 파이프라인에서 이를 올바르게 처리하는지 확인하시기 바랍니다.

선택 사항: UTF-8 BOM 제거

텍스트 처리 호환성을 위해 UTF-8 BOM을 제거할 수 있습니다:

#!/bin/bash
# Remove UTF-8 BOM from the file
tail -c +4 "data/Euthyphro by Plato.txt" > "data/Euthyphro by Plato.txt.tmp" && mv "data/Euthyphro by Plato.txt.tmp" "data/Euthyphro by Plato.txt"

In `@data/Euthyphro` by Plato.txt around lines 1 - 1508, File contains a UTF-8 BOM
(the invisible character '' / U+FEFF) at the start which can break text
processing; remove or explicitly handle this BOM in the ingestion/preprocessing
step. Fix by trimming the BOM before tokenization/embedding (either strip
leading U+FEFF in the loader or add a preprocessing step that removes it from
"Euthyphro by Plato.txt"); alternatively ensure the embedding pipeline's decoder
accepts BOMs. Locate the issue by checking the file start for the BOM character
'' (U+FEFF) and apply the BOM-stripping logic in the text loader or
preprocessing function that reads the file.
data/A Pickle for the Knowing Ones by Timothy Dexter.txt (3)

1-1677: 대용량 데이터 파일의 저장 전략 재고 필요

이 파일과 다른 Project Gutenberg 텍스트들을 Git 리포지토리에 직접 커밋하면 리포지토리 크기가 급격히 증가합니다. RAG 시스템용 데이터셋의 경우 다음 대안을 고려하세요:

  1. Git LFS: 대용량 파일 관리에 최적화
  2. GCS 버킷: GCP 마이그레이션 중이므로 Cloud Storage 활용
  3. 별도 데이터 리포지토리: 코드와 데이터 분리

현재 접근 방식은 개발 편의성은 높지만, 장기적으로 리포지토리 유지보수에 부담이 됩니다.

1677, The repository currently contains a large Project Gutenberg text file ("A
Pickle for the Knowing Ones by Timothy Dexter.txt") which will bloat git
history; remove this file from the main repo history and adopt a large-file
strategy: move the text to a cloud bucket (GCS) or a separate data-only repo and
re-add a lightweight pointer, or enable Git LFS and add the filename to
.gitattributes; update any ingestion scripts or CI that reference the file to
fetch from the new storage (GCS path or LFS pointer) and document the new data
retrieval steps.

1-1: UTF-8 BOM 제거 권장

파일이 UTF-8 BOM()으로 시작합니다. BOM은 텍스트 파싱 도구, 임베딩 모델, 토크나이저에서 문제를 일으킬 수 있습니다. RAG 시스템의 안정성을 위해 BOM을 제거하는 것이 좋습니다.

content.

1-1677: RAG 시스템용 메타데이터 추가 권장

텍스트 파일에 구조화된 메타데이터가 없어 RAG 시스템의 검색 품질과 필터링 기능이 제한될 수 있습니다. 각 문서에 대한 메타데이터를 추가하여 인덱싱과 검색을 개선하는 것이 좋습니다.

1-1758: 대용량 정적 데이터에 대한 스토리지 전략을 고려하세요.

이 텍스트 파일(~80KB)은 현재 크기로는 문제가 되지 않지만, RAG 시스템에 더 많은 문서를 추가할 계획이라면 스토리지 전략을 고려해야 합니다. PR 제목이 "migrate to gcp"인 것을 고려하면 다음 옵션을 검토하세요:

  1. Google Cloud Storage (GCS): 대용량 데이터 파일을 GCS 버킷에 저장하고 메타데이터만 Git에 유지
  2. Git LFS: 대용량 파일 관리를 위해 Git Large File Storage 사용
  3. 별도 데이터 저장소: 데이터와 코드를 분리하여 저장소 크기 관리 개선

현재 파일은 수용 가능하지만, 향후 확장성을 위해 데이터 관리 전략을 수립하는 것이 좋습니다.

large-file handling, or introduce a separate document datastore; update any code
that reads the file to fetch from GCS (or the chosen store) at build/runtime and

marker), then split_sections_by_heading() to detect and chunk by Roman-numeral /
ALL-CAPS headings (I., II., III., IV. and section titles like "BOURGEOIS AND

- Around line 48-49: The BMAD skill example in .agent/documents/bmad.md and the
generated story file documents/stories/001.clm-shared-system-core-module.md uses
a CLM (Contract Lifecycle Management) example that is unrelated to the Philo-RAG
project; update the example and the story content to use a Philo-RAG relevant
use case (e.g., "LangGraph-based multi-turn dialogue system" or "RAGAS-based
answer quality evaluation system") so the domain aligns with the project—search
for BMAD, the story filename 001.clm-shared-system-core-module.md, and any
references to "CLM" or "Contract Lifecycle Management" and replace them with the
chosen Philo-RAG use case, adjusting descriptions and intent examples
accordingly.

In @.agent/documents/stories/001.advanced_rag_system.md:
- Around line 47-49: The story claims a full "Strict Instruction" implementation
but the code in backend/app/services/llm.py (get_rag_prompt) only injects a
CRITICAL INSTRUCTION into the system prompt and lacks delimiters,
post-prompting, and sanitization; either update the story to accurately state
the current protections or implement the missing controls: in get_rag_prompt
wrap the user input with a unique delimiter (e.g., <<<USER_INPUT>>> ...
<<<END_USER_INPUT>>>), append a post-prompting reinforcement block after the
user input reiterating the strict instructions, and add a sanitization routine
(e.g., sanitize_input) that is invoked before building the prompt to
strip/escape malicious patterns—alternatively, if you choose to only update the
docs, edit 001.advanced_rag_system.md to list exactly which controls are present
(CRITICAL INSTRUCTION only) and which are missing (delimiter, post-prompting,
sanitization) so the story matches the code.

In @.github/workflows/deploy.yml:
- Around line 21-25: Replace long-lived JSON key usage in the GitHub Action auth
step (currently using credentials_json) with OIDC Workload Identity Federation
by configuring google-github-actions/auth@v2 to use workload_identity_provider
and service_account parameters (set your
projects/{PROJECT_ID}/locations/global/workloadIdentityPools/{POOL}/providers/{PROVIDER}
and the service account email) so GitHub exchanges short-lived OIDC tokens for
GCP credentials; additionally, stop injecting sensitive runtime values directly
into Cloud Run environment variables and instead fetch them from Google Secret
Manager (or another secure secret injection mechanism) at deploy/runtime to
avoid exposure in Cloud Run metadata.
- Around line 44-47: The workflow currently injects OPENAI_API_KEY, SUPABASE_URL
and SUPABASE_SERVICE_ROLE_KEY via env_vars which exposes them as plaintext
environment variables; change the google-github-actions/deploy-cloudrun@v2 step
to remove these keys from env_vars and instead add them under the action's
secrets parameter (mapping each env name to the Secret Manager resource, e.g.
OPENAI_API_KEY=<secret-name>:latest) so Cloud Run fetches them from Secret
Manager; ensure the referenced secret names exist and the Cloud Run service
account has secretmanager.secretAccessor permission.

In `@backend/app/services/embedding.py`:
- Around line 19-29: The startup pre-load is racing with incoming requests
because the background thread that initializes self._embeddings is not awaited;
change the initialization flow so the embedding model is fully loaded before the
app yields (e.g., add and call a synchronous init method like load_embeddings()
or await an async initialize_embeddings() from backend/app/main.py instead of
fire-and-forget), ensure the double-checked locking remains around
self._embeddings in the embedding class, and when constructing
HuggingFaceEmbeddings (the HuggingFaceEmbeddings(...) call that uses
model_name=MODEL_NAME and model_kwargs={'device': 'cpu'}), add a fixed revision
parameter (e.g., model_kwargs or the constructor revision argument) to pin the
model revision for reproducible downloads.
- Around line 24-25: The HuggingFaceEmbeddings instantiation in embedding.py
uses only MODEL_NAME which can pull varying artifacts; update the
self._embeddings = HuggingFaceEmbeddings(...) call to pass a fixed revision via
model_kwargs (e.g., include 'revision': '<commit-sha-or-tag>') and keep other
options like device and encode_kwargs (e.g., 'encode_kwargs':
{'normalize_embeddings': True}) so MODEL_NAME + model_kwargs ensure a
reproducible model; modify the HuggingFaceEmbeddings call (look for the
self._embeddings assignment) to add the model_kwargs with the chosen 40-char
commit SHA or tag.

In `@backend/Dockerfile`:
- Around line 1-28: The Dockerfile currently runs the container as root because
there is no USER directive; modify the Dockerfile to create a non-root user
(e.g., add a group and user like "appuser"), chown the application WORKDIR
(/app) to that user after COPY, and add a USER appuser (or USER
appuser:appgroup) before the CMD/ENTRYPOINT so the uvicorn process (CMD
["uvicorn", "app.main:app", ...]) runs unprivileged; ensure any files or
directories that need write access are owned by that user and avoid running
apt-get or pip as that user during build steps.

In `@backend/download_books.py`:
- Line 184: The code currently casts os.getenv("TARGET_COUNT", "300") directly
to int into the variable target_count which will raise ValueError and crash if
the env value is non-numeric; update the logic around target_count to parse
TARGET_COUNT with a safe try/except (or use str.isdigit/regex) and fall back to
the default 300 on parse error, then enforce a minimum value (e.g., if
parsed_value < 1 then set to 1) so target_count is always a valid positive
integer; reference and modify the target_count assignment site and any upstream
code that relies on it to use the validated value.

In `@data/As` a man thinketh by James Allen.txt:
- Line 1: The file starts with a BOM character (the first character in the
string "The Project Gutenberg eBook of As a man thinketh") which can corrupt
tokenization; open the file, remove any leading '\ufeff' (or read+write using
UTF-8 without BOM / use 'utf-8-sig' to strip it) and re-save the file as UTF-8
without BOM so the first token is clean for preprocessing, chunking, and
embedding.

In `@data/Critias` by Plato.txt:
- Line 1: The file begins with a UTF-8 BOM (U+FEFF) which can break embedding,
chunking and string comparisons; open "data/Critias by Plato.txt", remove the
leading BOM character (or re-save the file as "UTF-8 without BOM"), and commit
the cleaned file; if there are readers in code (e.g. any text loading functions)
ensure they strip a leading U+FEFF when present to avoid future issues.

In `@data/Dhammapada` a Collection of Verses Being One of the Canonical Books of
the Buddhists.txt:
- Line 1: The file begins with a BOM (U+FEFF) before the text "The Project
Gutenberg eBook of Dhammapada, a Collection of Verses; Being One of the
Canonical Books of the Buddhists" which can corrupt first-token parsing; remove
the leading BOM (U+FEFF) so the first character is the "T" of that title and
re-save the file as UTF-8 without BOM (ensure any editors or tooling used do not
reintroduce BOM).

In `@data/How` to Live on 24 Hours a Day by Arnold Bennett.txt:
- Line 1: The file "How to Live on 24 Hours a Day by Arnold Bennett.txt" begins
with a UTF-8 BOM (the leading '' character); remove the BOM so downstream
parsers and embedding/RAG pipelines don't mis-read the first token. Open that
file and strip the UTF-8 BOM from the start (or re-save the file using UTF-8
without BOM / read with UTF-8-sig and rewrite as UTF-8) ensuring the first byte
sequence no longer contains EF BB BF; then verify the file's first character is
the expected text (no hidden BOM) before committing.

In `@data/Ion` by Plato.txt:
- Line 1: Remove the hidden UTF-8 BOM (\uFEFF) at the start of "Ion by
Plato.txt" (present on Line 1) and re-save the file as UTF-8 without BOM so
loaders/tokenizers won't see a contaminated first token; ensure the file
encoding is normalized (no BOM) and verify the first character is "T" of "The
Project Gutenberg eBook of Ion" after the change.
- Around line 855-1200: The strip_gutenberg_boilerplate() function currently
only truncates at the END marker using text = text[:end_idx], leaving the
"START: FULL LICENSE" section (and everything after) in the input and polluting
embeddings; update the logic in strip_gutenberg_boilerplate() to detect the
"START: FULL LICENSE" marker (or its lowercase/variant forms) after the END
marker and trim the text to remove that entire license block (i.e., set the
truncated text to the portion before the START marker if present), ensuring both
'*** END OF THE PROJECT GUTENBERG EBOOK ***' and the subsequent 'START: FULL
LICENSE' section are removed from the returned text.

In `@data/The` Communist Manifesto by Karl Marx and Friedrich Engels.txt:
- Line 1: The file begins with a UTF-8 BOM which breaks the RAG pipeline; fix
the loader to strip BOM by opening the file with encoding='utf-8-sig' when
reading (e.g., use open(..., encoding='utf-8-sig') in your RAG loader) or strip
it after read using a Unicode replace like re.sub(r'\ufeff', '', text);
alternatively ensure the source file is saved as UTF-8 without BOM so that
tokenization, chunking, and embedding (the text ingestion path) receive clean
text.

In `@data/The` Declaration of Independence of the United States of America by
Thomas Jefferson.txt:
- Around line 256-606: The file contains Project Gutenberg license text that
must be excluded from embedding; update the preprocessing pipeline so
extract_gutenberg_content locates the START/END markers (use
start_pattern/end_pattern) and splits the parsed text into two parts: main_text
(the Declaration content) and license_text (the Project Gutenberg terms),
storing title/author in metadata and placing the license into
metadata['license_text'] only; then ensure chunk_for_rag is called with
result['main_text'] (not result['content'] or the license), and that
chunk_for_rag (function name) performs paragraph-based semantic chunking with
chunk_size/overlap parameters so only the actual declaration is embedded for
RAG.
- Around line 1-88: The file contains a large Project Gutenberg header/meta
section mixed with the Declaration text which will pollute embeddings; extract
the Project Gutenberg header/editor notes (the "Project Gutenberg" header and
"Transcribers’ Notes"/editorial blocks) into a structured metadata record
(JSON/YAML) capturing title, author, ebook id, release and update dates,
license, source and the content span, write the pure Declaration body to a
separate content file (to be used for tokenization/embedding and retrieval), and
ensure ingestion code uses the content-only file for vectorization while storing
the metadata record as document properties in the DB so it is available for
UI/display and filtering.
- Around line 89-255: The PR summary incorrectly mentions a "한국어 메타데이터 업데이트
스크립트" while the data directory (e.g., file "The Declaration of Independence of
the United States of America by Thomas Jefferson.txt") contains only
English/German/Chinese/Latin texts; update the PR by either (A) removing the
Korean-script claim and clearly stating the actual languages present, or (B) if
Korean support is intended, add the Korean philosophy texts and the referenced
metadata update script (or include the script in the PR) and document the plan
for future Korean additions; ensure the PR description, any mention of "한국어
메타데이터 업데이트 스크립트", and the repository metadata are consistent.

In `@README.md`:
- Line 1: Remove the UTF-8 BOM at the start of the README header line so the
file begins with the plain header text "Philo-RAG (철학자와의 대화)" instead of "#
Philo-RAG (철학자와의 대화)"; open README.md, delete the invisible BOM character
immediately before the leading '#' (or re-save the file without BOM/with UTF-8
no BOM), and verify the first line now starts exactly with "# Philo-RAG (철학자와의
대화)".
- Around line 223-225: Remove the duplicated English instruction "Open
`http://localhost:3000` to start using the system." in README.md so the sentence
appears only once; locate both consecutive occurrences of that exact sentence
and delete one of them, leaving a single instance for clarity.

Nitpick comments:
In `@backend/scripts/check_db.py`:
- Line 5: Change the sys.path modification in check_db.py from
sys.path.append(...) to sys.path.insert(0, ...) so the project root is placed at
the front of sys.path (matching verify_and_clear.py and update_metadata.py) to
ensure project modules take precedence when importing; update the single call to
sys.path.append(os.path.dirname(os.path.dirname(os.path.abspath(__file__)))) to
use sys.path.insert(0, ...) with the same computed path.

In `@backend/scripts/ingest_data.py`:
- Around line 45-46: 함수 fetch_aladin_metadata가 끝난 직후 UUID_NAMESPACE 정의 전에 빈 줄
2개를 추가해서 PEP 8 함수 정의 후 공백 규칙을 준수하도록 수정하세요; 구체적으로 fetch_aladin_metadata 종료 블록과
UUID_NAMESPACE = uuid.UUID("6f0bdf73-9cc8-4e34-a302-a12037f0ac6d") 사이에 두 줄의 빈 줄을
삽입하면 됩니다.

In `@data/A` Pickle for the Knowing Ones by Timothy Dexter.txt:
- Around line 1-1677: The repository currently contains a large Project
Gutenberg text file ("A Pickle for the Knowing Ones by Timothy Dexter.txt")
which will bloat git history; remove this file from the main repo history and
adopt a large-file strategy: move the text to a cloud bucket (GCS) or a separate
data-only repo and re-add a lightweight pointer, or enable Git LFS and add the
filename to .gitattributes; update any ingestion scripts or CI that reference
the file to fetch from the new storage (GCS path or LFS pointer) and document
the new data retrieval steps.
- Line 1: The file "A Pickle for the Knowing Ones by Timothy Dexter.txt" begins
with a UTF-8 BOM; remove the BOM character at the start of the file so
downstream parsers/tokenizers and RAG components don't fail—open the file and
strip the leading U+FEFF (UTF-8 BOM) from the very beginning (e.g., trim the
first byte-sequence EF BB BF) and save the file without altering the rest of the
content.
- Around line 1-1677: Add a JSON sidecar metadata file for this document (e.g.,
create data/A Pickle for the Knowing Ones by Timothy Dexter.json) containing
keys like document_id (use "gutenberg-43453"), title ("A Pickle for the Knowing
Ones"), author ("Timothy Dexter"), publication_year (1848), source ("Project
Gutenberg"), source_url ("https://www.gutenberg.org/ebooks/43453"), language
("en"), topics (array such as
["biography","american-literature","19th-century"]), gutenberg_id (43453),
encoding ("utf-8") and license ("public-domain") so your RAG/indexer can ingest
and filter the text; ensure the JSON is valid UTF-8 and matches the filename
exactly.

In `@data/As` a man thinketh by James Allen.txt:
- Around line 1-1338: The filename "As a man thinketh by James Allen.txt"
contains spaces which break CLI/batch processing; rename the file to a safe,
consistent identifier (suggestion: as_a_man_thinketh_james_allen.txt) and update
any references (scripts, manifests, tests, or import lists) that use the
original name (search for the exact string "As a man thinketh by James
Allen.txt") to the new name to avoid quoting issues in automation.

In `@data/Euthyphro` by Plato.txt:
- Around line 1-1508: File contains a UTF-8 BOM (the invisible character '' /
U+FEFF) at the start which can break text processing; remove or explicitly
handle this BOM in the ingestion/preprocessing step. Fix by trimming the BOM
before tokenization/embedding (either strip leading U+FEFF in the loader or add
a preprocessing step that removes it from "Euthyphro by Plato.txt");
alternatively ensure the embedding pipeline's decoder accepts BOMs. Locate the
issue by checking the file start for the BOM character '' (U+FEFF) and apply
the BOM-stripping logic in the text loader or preprocessing function that reads
the file.

In `@data/How` to Live on 24 Hours a Day by Arnold Bennett.txt:
- Around line 1-1758: The repo currently contains a large static text file ("How
to Live on 24 Hours a Day by Arnold Bennett.txt") which will not scale as you
add more documents (PR title: "migrate to gcp"); move large/immutable documents
out of the git repo and adopt a storage strategy: upload the full text files to
Google Cloud Storage (preferred given the GCP migration) and keep only
lightweight metadata/paths in the repo, or if you must keep files near code use
Git LFS for large-file handling, or introduce a separate document datastore;
update any code that reads the file to fetch from GCS (or the chosen store) at
build/runtime and add documentation/CI steps to provision and access the bucket.

In `@data/Index` of the Project Gutenberg Works of Lucius Annaeus Seneca by Lucius
Annaeus Seneca.txt:
- Line 1: The file starts with a UTF-8 BOM (U+FEFF) on Line 1 which can break
indexing/chunking; open the file "Index of the Project Gutenberg Works of Lucius
Annaeus Seneca by Lucius Annaeus Seneca.txt", remove the leading BOM character
(strip any U+FEFF at the very start or delete the invisible character on Line 1)
and re-save the file as UTF-8 without BOM so the file begins with the printable
text "The Project Gutenberg eBook..." instead of the BOM.

In `@data/The` Communist Manifesto by Karl Marx and Friedrich Engels.txt:
- Around line 1-1795: The file lacks structured metadata and needs a
preprocessing script to clean and chunk it for RAG: implement a preprocessing
pipeline (e.g., preprocess_gutenberg()) that calls
remove_gutenberg_header_footer() to strip Gutenberg header (lines ~1-52) and
trailing license (lines after the end marker), then split_sections_by_heading()
to detect and chunk by Roman-numeral / ALL-CAPS headings (I., II., III., IV. and
section titles like "BOURGEOIS AND PROLETARIANS") producing section-level
documents, attach metadata (author, section_name, start_pos, end_pos, source)
and finally export_to_jsonl()/write_json_documents() to write each chunk as
JSON/JSONL; ensure header/footer removal and section detection are configurable
and robust to minor formatting variations.

In `@data/The` Declaration of Independence of the United States of America by
Thomas Jefferson.txt:
- Line 1: The file "The Declaration of Independence of the United States of
America by Thomas Jefferson.txt" contains a UTF-8 BOM at the start; remove the
BOM so downstream text processors and embedding tools don’t misbehave by
reopening the file with a BOM-aware reader (e.g., read with utf-8-sig or strip
the BOM) and then overwrite the file with plain UTF-8 content without the BOM;
ensure the saved file begins with the first character of the text, not the BOM.

⚠️ Potential issue | 🟠 Major

보안 구현 상태가 실제 코드와 불일치합니다.

Line 47에서 "Strict Instruction 추가 (이미 구현됨: llm.py: get_rag_prompt)"라고 명시하고 있으나, 실제 코드(backend/app/services/llm.py:81-106)를 확인한 결과 다음과 같은 차이가 있습니다:

현재 구현된 것:

  • 시스템 프롬프트에 CRITICAL INSTRUCTION 텍스트만 추가 (LLM에게 인젝션 시도 거부 요청)

구현되지 않은 것:

  • 사용자 입력 주변에 Delimiter 구분자 없음 (보안 가이드라인 Line 12-14 참조)
  • Post-Prompting 기법 미적용 (사용자 입력 후 지침 재강조 없음)
  • 입력 데이터 검증(Sanitization) 로직 없음

현재는 LLM 기반 방어만 존재하며, 구조적 보안 조치(delimiter, post-prompting)가 누락되어 있습니다. 스토리 문서에서 구현 상태를 정확히 표기하거나, 실제로 보안 조치를 구현해야 합니다.

📋 권장 수정안

스토리 문서의 보안 섹션을 다음과 같이 수정하여 현재 상태를 정확히 반영하세요:

 ### 프롬프트 인젝션 방지 (Anti-Injection)
-- 시스템 프롬프트에 `Strict Instruction` 추가 (이미 구현됨: `llm.py: get_rag_prompt`).
-- 입력 데이터 검증(Sanitization) 로직 추가.
-- `Post-Prompting` 기법을 사용하여 사용자 입력 후에 핵심 지침 재강조.
+- **부분 구현:** 시스템 프롬프트에 기본적인 인젝션 거부 지침 추가됨 (`llm.py: get_rag_prompt`).
+- **구현 필요:**

The story claims a full "Strict Instruction" implementation but the code in
backend/app/services/llm.py (get_rag_prompt) only injects a CRITICAL INSTRUCTION
into the system prompt and lacks delimiters, post-prompting, and sanitization;
either update the story to accurately state the current protections or implement
the missing controls: in get_rag_prompt wrap the user input with a unique
delimiter (e.g., <<<USER_INPUT>>> ... <<<END_USER_INPUT>>>), append a
post-prompting reinforcement block after the user input reiterating the strict
instructions, and add a sanitization routine (e.g., sanitize_input) that is
invoked before building the prompt to strip/escape malicious
patterns—alternatively, if you choose to only update the docs, edit
001.advanced_rag_system.md to list exactly which controls are present (CRITICAL
INSTRUCTION only) and which are missing (delimiter, post-prompting,
sanitization) so the story matches the code.

google-github-actions/auth v2 OIDC Workload Identity Federation GitHub Actions

💡 Result:

The google-github-actions/auth is a GitHub Action for authenticating to Google Cloud, with primary support for Workload Identity Federation (WIF) using OIDC tokens from GitHub Actions. This enables keyless authentication, avoiding long-lived service account keys. v2 and v3 both fully support OIDC WIF. The repo's latest release is v3.0.0 (2025-08-28). v3 requires Node 24 runners (ubuntu-latest is fine) and removes some deprecated parameters, but WIF configuration remains identical. ## Setup WIF (GCP side) 1. Create Workload Identity Pool: gcloud iam workload-identity-pools create my-pool --project=my-project --location=global 2. Create OIDC Provider: gcloud iam workload-identity-pools providers create-oidc my-provider \ --project=my-project --location=global --workload-identity-pool=my-pool \ --display-name=GitHub --attribute-mapping="google.subject=assertion.sub,attribute.actor=assertion.actor,attribute.repository=assertion.repository" \ --issuer-uri=https://token.actions.githubusercontent.com \ --attribute-condition=assertion.repository_owner=="my-org" && assertion.repository=="my-org/my-repo" Full provider ID: projects/my-project/locations/global/workloadIdentityPools/my-pool/providers/my-provider 3. (Preferred for most resources) Create Service Account and allow impersonation: gcloud iam service-accounts create my-sa --project=my-project gcloud iam service-accounts add-iam-policy-binding my-sa@my-project.iam.gserviceaccount.com \ --project=my-project --role=roles/iam.workloadIdentityUser \ --member=principalSet://iam.googleapis.com/projects/my-project/locations/global/workloadIdentityPools/my-pool/providers/my-provider Grant the SA IAM roles for your resources. Direct WIF (no SA) is possible but limited (10min tokens, not all services support principalSet). ## GitHub Actions Workflow yaml name: Example on: [push] permissions: contents: read id-token: write # Required for OIDC token jobs: auth: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - id: auth uses: google-github-actions/auth@v3 # or @v2 with: workload_identity_provider: projects/my-project/locations/global/workloadIdentityPools/my-pool/providers/my-provider service_account: my-sa@my-project.iam.gserviceaccount.com project_id: my-project - run: gcloud run deploy ... # gcloud, gsutil, etc. now authenticated ## Key Benefits - Short-lived tokens (1hr max) - Scoped by repo/branch/workflow via attribute conditions - No secrets stored in GitHub ## Troubleshooting - Propagation delay: up to 5min - GitHub OIDC token expires in 5min; use early in job - Check https://github.com/google-github-actions/auth/blob/main/docs/TROUBLESHOOTING.md

장기 서비스 계정 키 기반 인증을 GitHub OIDC + Workload Identity Federation으로 전환하세요.

현재 line 24에서 credentials_json: ${{ secrets.GCP_SA_KEY }}로 JSON 키를 사용하는 방식은 장기 보관되는 자격증명으로 유출 위험이 높습니다. google-github-actions/auth@v2는 OIDC 및 Workload Identity Federation을 지원하므로, 다음과 같이 변경하여 단기 토큰(최대 1시간) 기반의 보안을 강화하세요:

      - name: Google Auth
        uses: google-github-actions/auth@v2
        with:

          service_account: {SERVICE_ACCOUNT}@{PROJECT_ID}.iam.gserviceaccount.com

추가로 lines 44-47에서 민감한 런타임 값들을 환경변수로 직접 주입하는 것도 Cloud Run 메타데이터에 노출될 수 있으니, 가능하면 Google Secret Manager 또는 보안이 강화된 방식으로 주입하세요.

google-github-actions deploy-cloudrun env_vars secrets best practices

💡 Result:

Best practices for deploying to Google Cloud Run using Google GitHub Actions with environment variables and secrets: ## Authentication (Highest Priority) Use Workload Identity Federation (WIF) instead of service account keys for secure, keyless authentication. Avoid storing long-lived credentials in GitHub secrets. 1. Create a service account with minimal roles: roles/run.admin, roles/artifactregistry.writer, roles/iam.serviceAccountUser, roles/iam.workloadIdentityUser. 2. Set up a workload identity pool and OIDC provider for GitHub. 3. Allow the service account to impersonate via WIF. 4. In workflow: permissions: contents: 'read' id-token: 'write' - uses: 'google-github-actions/auth@v2' with: workload_identity_provider: 'projects/PROJECT_NUMBER/locations/global/workloadIdentityPools/POOL/providers/PROVIDER' service_account: 'sa@project.iam.gserviceaccount.com' ## Deployment Action Use the official google-github-actions/deploy-cloudrun@v2 action. Example workflow: - id: deploy uses: 'google-github-actions/deploy-cloudrun@v2' with: service: my-service region: us-central1 image: us-docker.pkg.dev/PROJECT/REPO/image:tag ## Environment Variables (Non-sensitive) Use env_vars input for configuration like NODE_ENV=production. Supports multiline YAML. - env_vars_update_strategy: merge (default) or overwrite. env_vars: |- NODE_ENV=production BASE_URL=https://example.com Max 1000 vars, 32KB total length. ## Secrets (Sensitive Data) Never store secrets as plain env vars in GitHub secrets or deployment. Use Google Secret Manager references. 1. Create secrets in Secret Manager. 2. Grant Cloud Run service account roles/secretmanager.secretAccessor. 3. Reference in deployment: ENV=secret-name:latest (pin versions for env vars). In action: secrets: |- DB_PASSWORD=db-secret:latest API_KEY=api-secret:1 /secrets/tls/key=tls-secret:latest # volume mount - Keys without / become env vars. - Paths with / mount as volumes. - secrets_update_strategy: merge (default). Secret Manager fetches values at startup (env) or read-time (volumes). Use volumes for rotation without restarts. ## Additional Best Practices - Use GitHub Environments for prod deployments with approvals. - Template service YAML for complex configs, substitute vars. - Pin action versions (e.g., @v2). - Limit secrets to necessary access; use dedicated service accounts. - For multiline secrets, quote properly in YAML. - Monitor with GitHub secret scanning; rotate regularly. - Don't print secrets in logs; GitHub masks them automatically. This approach ensures secrets never appear in GitHub secrets, logs, or manifests.

Cloud Run Secret Manager environment variables exposure risk

💡 Result:

Using Secret Manager secrets as environment variables in Cloud Run carries exposure risks primarily within the running container and potential logging issues, though the secret values themselves are not stored in plaintext in service configurations. Key risks: - Inside the container: Secrets are injected as plaintext environment variables at startup. Any process in the container, vulnerability, or debugging tool (e.g., 'env' command) can access them. They persist in process memory. - Logging and dumps: Application code might accidentally log env vars. Crash dumps or memory dumps could capture them. - Visibility: Users with Cloud Run Viewer/Developer IAM roles can see env var names and Secret Manager references via 'gcloud run services describe' or console, but not the secret values. Plaintext env vars (not from Secret Manager) are visible in full. - Detection: Google Sensitive Data Protection scans and flags plaintext secrets in env vars as vulnerabilities. Mitigations and best practices (from official docs): - Prefer mounting secrets as volumes over env vars to limit exposure (readable only from file, not inherited by child processes as easily). - Use Secret Manager references (--set-secrets=ENV=secret:latest) instead of plaintext --set-env-vars; values fetched dynamically at instance start. - Pin secret versions (avoid 'latest' for env vars to prevent failed startups on version issues). - Grant minimal IAM: Cloud Run service account needs roles/secretmanager.secretAccessor only on specific secrets. - Avoid printing env vars in code; use Secret Manager client libraries for runtime fetch if higher security needed. - Enable VPC Service Controls, audit logs. Secret Manager integration improves security over plaintext env vars by keeping values out of deployments/logs/configs, but env var injection still exposes them in-memory during runtime.

첫 요청의 모델 로딩 비용은 여전히 위험합니다: 시작 시 백그라운드 로드가 경쟁 조건을 가집니다.

Startup 시 모델 pre-loading을 시도하지만(backend/app/main.py 라인 30), 로드가 완료될 때까지 기다리지 않고 즉시 yield(라인 44)하므로 경쟁 조건이 발생합니다. 시작 후 몇 초 내의 요청은 아직 진행 중인 백그라운드 스레드 로드보다 먼저 도착할 수 있으며, 첫 embedding 호출이 여전히 모델 다운로드/초기화 시간을 부담하게 됩니다.

또한 sentence-transformers/all-MiniLM-L6-v2는 revision parameter 없이 로드되므로 모델 아티팩트가 Hugging Face에서 변경되면 cold start마다 다른 버전을 받을 수 있습니다(재현성 저하). 모델 다운로드를 보장하거나 revision을 고정하는 것이 좋습니다.

Title: The Declaration of Independence of the United States of America

Author: Thomas Jefferson



Release date: December 1, 1971 [eBook #1]
Most recently updated: September 2, 2025

Language: English

Other information and formats: www.gutenberg.org/ebooks/1

Credits: This etext was produced by Michael S. Hart.


*** START OF THE PROJECT GUTENBERG EBOOK THE DECLARATION OF INDEPENDENCE OF THE UNITED STATES OF AMERICA ***


The United States Declaration of Independence was the first E-text
released by Project Gutenberg, early in 1971. The title was stored
in an emailed instruction set which required a tape or diskpack be
hand mounted for retrieval. The disk pack was the size of a large
cake in a cake carrier, cost $1500, and contained 5 megabytes, of
which this file took 1-2%. Two tape backups were kept plus one on
paper tape. The 10,000 files we hope to have online by the end of
2001 should take about 1-2% of a comparably priced drive in 2001.

This file was never copyrighted, Sharewared, etc., and is thus for
all to use and copy in any manner they choose. Please feel free to
make your own edition using this as a base.

In my research for creating this transcription of our first Etext,
I have come across enough discrepancies [even within that official
documentation provided by the United States] to conclude that even
“facsimiles” of the Declaration of Independence are nary identical
to the original, nor of other “facsimiles.” There is a plethora of
variations in capitalizations, punctuation, and where names appear
on the documents [which names I have left out].

The resulting document has several misspellings removed from those
parchment “facsimiles” I used back in 1971, and which I should not
be able to easily find at this time, including “Brittain.”

[JT, Apr 2005: “Brittish” is spelled as in the original.]

[RO, Aug 2025: Dr. Hart’s original fully-justified columns of text
in the plain text version have been restored for the introduction.
Minor text alterations were made to do so.]

Transcribers’ Notes

NOTE: This file contains the original contents of the
very first eBook in the Project Gutenberg collection,
the Declaration of Independence. This file previously
contained a compilation of etexts from #2 to #9. Also
it contained a duplicate of the Declaration - as part
of preserving the history of the contents which isn’t
necessary any longer. The historical variations of #1
are included in the “old” subdirectory accessed under
the “More Files” listing in the landing page for this
file. No edits or changes have been made to them.

All of the original Project Gutenberg Etexts from the
1970’s were produced in ALL CAPS, no lower case. The
computers we used then didn’t have lower case at all.

IN CONGRESS, July 4, 1776

The unanimous Declaration of the thirteen united States of America

When in the Course of human events, it becomes necessary for one people
to dissolve the political bands which have connected them with another,
and to assume, among the Powers of the earth, the separate and equal
station to which the Laws of Nature and of Nature’s God entitle them,
a decent respect to the opinions of mankind requires that they should
declare the causes which impel them to the separation.

We hold these truths to be self-evident, that all men are created
equal, that they are endowed by their Creator with certain unalienable
Rights, that among these are Life, Liberty, and the pursuit of
Happiness. That to secure these rights, Governments are instituted
among Men, deriving their just powers from the consent of the governed,
That whenever any Form of Government becomes destructive of these
ends, it is the Right of the People to alter or to abolish it, and to
institute new Government, laying its foundation on such principles
and organizing its powers in such form, as to them shall seem most
likely to effect their Safety and Happiness. Prudence, indeed, will
dictate that Governments long established should not be changed for
light and transient causes; and accordingly all experience hath shown,
that mankind are more disposed to suffer, while evils are sufferable,
than to right themselves by abolishing the forms to which they are
accustomed. But when a long train of abuses and usurpations, pursuing
invariably the same Object evinces a design to reduce them under
absolute Despotism, it is their right, it is their duty, to throw off
such Government, and to provide new Guards for their future security.
--Such has been the patient sufferance of these Colonies; and such is
now the necessity which constrains them to alter their former Systems
of Government. The history of the present King of Great Britain is a
history of repeated injuries and usurpations, all having in direct
object the establishment of an absolute Tyranny over these States. To
prove this, let Facts be submitted to a candid world.

He has refused his Assent to Laws, the most wholesome and necessary for
the public good.

He has forbidden his Governors to pass Laws of immediate and pressing
importance, unless suspended in their operation till his Assent should
be obtained; and when so suspended, he has utterly neglected to attend
to them.

He has refused to pass other Laws for the accommodation of large
districts of people, unless those people would relinquish the right
of Representation in the Legislature, a right inestimable to them and
formidable to tyrants only.

He has called together legislative bodies at places unusual,
uncomfortable, and distant from the depository of their Public Records,
for the sole purpose of fatiguing them into compliance with his
measures.

He has dissolved Representative Houses repeatedly, for opposing with
manly firmness his invasions on the rights of the people.

He has refused for a long time, after such dissolutions, to cause
others to be elected; whereby the Legislative Powers, incapable of
Annihilation, have returned to the People at large for their exercise;
the State remaining in the mean time exposed to all the dangers of
invasion from without, and convulsions within.

He has endeavoured to prevent the population of these States; for that
purpose obstructing the Laws of Naturalization of Foreigners; refusing
to pass others to encourage their migration hither, and raising the
conditions of new Appropriations of Lands.

He has obstructed the Administration of Justice, by refusing his Assent
to Laws for establishing Judiciary Powers.

He has made judges dependent on his Will alone, for the tenure of their
offices, and the amount and payment of their salaries.

He has erected a multitude of New Offices, and sent hither swarms of
Officers to harass our People, and eat out their substance.

He has kept among us, in times of peace, Standing Armies without the
Consent of our legislatures.

He has affected to render the Military independent of and superior to
the Civil Power.

He has combined with others to subject us to a jurisdiction foreign to
our constitution, and unacknowledged by our laws; giving his Assent to
their Acts of pretended legislation:

For quartering large bodies of armed troops among us:

For protecting them, by a mock Trial, from Punishment for any Murders
which they should commit on the Inhabitants of these States:

For cutting off our Trade with all parts of the world:

For imposing taxes on us without our Consent:

For depriving us, in many cases, of the benefits of Trial by Jury:

For transporting us beyond Seas to be tried for pretended offences:

For abolishing the free System of English Laws in a neighbouring
Province, establishing therein an Arbitrary government, and enlarging
its Boundaries so as to render it at once an example and fit instrument
for introducing the same absolute rule into these Colonies:

For taking away our Charters, abolishing our most valuable Laws, and
altering fundamentally the Forms of our Governments:

For suspending our own Legislatures, and declaring themselves invested
with Power to legislate for us in all cases whatsoever.

He has abdicated Government here, by declaring us out of his Protection
and waging War against us.

He has plundered our seas, ravaged our Coasts, burnt our towns, and
destroyed the lives of our people.

He is at this time transporting large armies of foreign mercenaries
to compleat the works of death, desolation and tyranny, already begun
with circumstances of Cruelty & perfidy scarcely paralleled in the most
barbarous ages, and totally unworthy of the Head of a civilized nation.

He has constrained our fellow Citizens taken Captive on the high Seas
to bear Arms against their Country, to become the executioners of their
friends and Brethren, or to fall themselves by their Hands.

He has excited domestic insurrections amongst us, and has endeavoured
to bring on the inhabitants of our frontiers, the merciless Indian
Savages, whose known rule of warfare, is an undistinguished destruction
of all ages, sexes and conditions.

In every stage of these Oppressions We have Petitioned for Redress in
the most humble terms: Our repeated Petitions have been answered only
by repeated injury. A Prince, whose character is thus marked by every
act which may define a Tyrant, is unfit to be the ruler of a free
People.

Nor have We been wanting in attention to our British brethren. We have
warned them from time to time of attempts by their legislature to
extend an unwarrantable jurisdiction over us. We have reminded them
of the circumstances of our emigration and settlement here. We have
appealed to their native justice and magnanimity, and we have conjured
them by the ties of our common kindred to disavow these usurpations,
which would inevitably interrupt our connections and correspondence.
They too have been deaf to the voice of justice and of consanguinity.
We must, therefore, acquiesce in the necessity, which denounces our
Separation, and hold them, as we hold the rest of mankind, Enemies in
War, in Peace Friends.

We, therefore, the Representatives of the United States of America,
in General Congress, Assembled, appealing to the Supreme Judge of the
world for the rectitude of our intentions, do, in the Name, and by the
Authority of the good People of these Colonies, solemnly publish and
declare, That these United Colonies are, and of Right ought to be Free
and Independent States; that they are Absolved from all Allegiance to
the British Crown, and that all political connection between them and
the State of Great Britain, is and ought to be totally dissolved; and
that as Free and Independent States, they have full Power to levy War,
conclude Peace, contract Alliances, establish Commerce, and to do all
other Acts and Things which Independent States may of right do. And for
the support of this Declaration, with a firm reliance on the Protection
of Divine Providence, we mutually pledge to each other our Lives, our
Fortunes and our sacred Honor.

forth in Section 3 below.

1.F.

1.F.1. Project Gutenberg volunteers and employees expend considerable
effort to identify, do copyright research on, transcribe and proofread
works not protected by U.S. copyright law in creating the Project
Gutenberg™ collection. Despite these efforts, Project Gutenberg™
electronic works, and the medium on which they may be stored, may
contain “Defects,” such as, but not limited to, incomplete, inaccurate
or corrupt data, transcription errors, a copyright or other
intellectual property infringement, a defective or damaged disk or
other medium, a computer virus, or computer codes that damage or
cannot be read by your equipment.

1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the “Right
of Replacement or Refund” described in paragraph 1.F.3, the Project
Gutenberg Literary Archive Foundation, the owner of the Project

Gutenberg™ electronic work under this agreement, disclaim all
liability to you for damages, costs and expenses, including legal

PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE
TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
DAMAGE.

1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a
defect in this electronic work within 90 days of receiving it, you can
receive a refund of the money (if any) you paid for it by sending a
written explanation to the person you received the work from. If you
received the work on a physical medium, you must return the medium

or entity providing it to you may choose to give you a second
opportunity to receive the work electronically in lieu of a refund. If
the second copy is also defective, you may demand a refund in writing
without further opportunities to fix the problem.

1.F.4. Except for the limited right of replacement or refund set forth
in paragraph 1.F.3, this work is provided to you ‘AS-IS’, WITH NO
OTHER WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT
LIMITED TO WARRANTIES OF MERCHANTABILITY OR FITNESS FOR ANY PURPOSE.

1.F.5. Some states do not allow disclaimers of certain implied
warranties or the exclusion or limitation of certain types of
damages. If any disclaimer or limitation set forth in this agreement
violates the law of the state applicable to this agreement, the
agreement shall be interpreted to make the maximum disclaimer or
limitation permitted by the applicable state law. The invalidity or
unenforceability of any provision of this agreement shall not void the
remaining provisions.

1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the

additions or deletions to any Project Gutenberg work, and (c) any
Defect you cause.

Section 2. Information about the Mission of Project Gutenberg

Project Gutenberg is synonymous with the free distribution of
electronic works in formats readable by the widest variety of
computers including obsolete, old, middle-aged and new computers. It
exists because of the efforts of hundreds of volunteers and donations
from people in all walks of life.

Volunteers and financial support to provide volunteers with the
assistance they need are critical to reaching Project Gutenberg’s
goals and ensuring that the Project Gutenberg collection will
remain freely available for generations to come. In 2001, the Project
Gutenberg Literary Archive Foundation was created to provide a secure
and permanent future for Project Gutenberg and future
generations. To learn more about the Project Gutenberg Literary
Archive Foundation and how your efforts and donations can help, see
Sections 3 and 4 and the Foundation information page at www.gutenberg.org.

Section 3. Information about the Project Gutenberg Literary Archive Foundation

The Project Gutenberg Literary Archive Foundation is a non-profit
501(c)(3) educational corporation organized under the laws of the
state of Mississippi and granted tax exempt status by the Internal
Revenue Service. The Foundation’s EIN or federal tax identification
number is 64-6221541. Contributions to the Project Gutenberg Literary
Archive Foundation are tax deductible to the full extent permitted by

Section 4. Information about Donations to the Project Gutenberg
Literary Archive Foundation

Project Gutenberg™ depends upon and cannot survive without widespread
public support and donations to carry out its mission of
increasing the number of public domain and licensed works that can be
freely distributed in machine-readable form accessible by the widest
array of equipment including outdated equipment. Many small donations
($1 to $5,000) are particularly important to maintaining tax exempt
status with the IRS.

The Foundation is committed to complying with the laws regulating
charities and charitable donations in all 50 states of the United
States. Compliance requirements are not uniform and it takes a
considerable effort, much paperwork and many fees to meet and keep up
with these requirements. We do not solicit donations in locations
where we have not received written confirmation of compliance. To SEND
DONATIONS or determine the status of compliance for any particular state
visit www.gutenberg.org/donate.

While we cannot and do not solicit contributions from states where we
have not met the solicitation requirements, we know of no prohibition
against accepting unsolicited donations from donors in such states who

International donations are gratefully accepted, but we cannot make
any statements concerning tax treatment of donations received from

Section 5. General Information About Project Gutenberg electronic works

Professor Michael S. Hart was the originator of the Project
Gutenberg concept of a library of electronic works that could be
freely shared with anyone. For forty years, he produced and
distributed Project Gutenberg eBooks with only a loose network of
volunteer support.

Project Gutenberg eBooks are often created from several printed
editions, all of which are confirmed as not protected by copyright in
the U.S. unless a copyright notice is included. Thus, we do not
necessarily keep eBooks in compliance with any particular paper
edition.

Most people start at our website which has the main PG search
facility: www.gutenberg.org.

This website includes information about Project Gutenberg,
including how to make donations to the Project Gutenberg Literary
Archive Foundation, how to help produce our new eBooks, and how to
subscribe to our email newsletter to hear about new eBooks.

⚠️ Potential issue | 🟠 Major

RAG 청킹 전략 수립 및 라이선스 텍스트 분리 필수

파일의 약 58%(351줄)가 Project Gutenberg 라이선스 및 약관으로 구성되어 있습니다. 이는 법적 준수를 위해 필요하지만, RAG 시스템의 임베딩 및 검색 대상에서는 반드시 제외되어야 합니다.

문제점:

  • 라이선스 텍스트가 임베딩되면 검색 품질이 심각하게 저하됩니다
  • 사용자 쿼리가 라이선스 조항과 매칭될 수 있어 관련 없는 결과가 반환됩니다
  • 전체 파일의 대부분이 비콘텐츠 텍스트로 구성되어 있습니다

필수 조치:

  1. 문서 청킹 파이프라인 구현
  2. 콘텐츠(라인 89-255)와 라이선스(라인 256-606) 분리
  3. 라이선스 정보는 문서 메타데이터로만 보관
  4. 실제 선언문 텍스트만 의미론적 청크로 분할하여 임베딩

In `@data/The` Declaration of Independence of the United States of America by
Thomas Jefferson.txt around lines 256 - 606, The file contains Project Gutenberg
license text that must be excluded from embedding; update the preprocessing
pipeline so extract_gutenberg_content locates the START/END markers (use
start_pattern/end_pattern) and splits the parsed text into two parts: main_text
(the Declaration content) and license_text (the Project Gutenberg terms),
storing title/author in metadata and placing the license into
metadata['license_text'] only; then ensure chunk_for_rag is called with
result['main_text'] (not result['content'] or the license), and that
chunk_for_rag (function name) performs paragraph-based semantic chunking with
chunk_size/overlap parameters so only the actual declaration is embedded for
RAG.

Line 1의 BOM 문자 제거가 필요합니다.

헤더 앞 UTF-8 BOM()이 포함되어 있어 일부 렌더러/도구에서 제목 인식이나 문자열 비교가 어긋날 수 있습니다. BOM 없는 일반 텍스트로 저장해 주세요.

In `@README.md` at line 1, Remove the UTF-8 BOM at the start of the README header
line so the file begins with the plain header text "Philo-RAG (철학자와의 대화)"
instead of "# Philo-RAG (철학자와의 대화)"; open README.md, delete the invisible BOM
character immediately before the leading '#' (or re-save the file without
BOM/with UTF-8 no BOM), and verify the first line now starts exactly with "#
Philo-RAG (철학자와의 대화)".
