Inline comments:
In `@apps/backend/src/entities/users.rs`:
- Around line 20-24: The project is missing the database migration that matches
the users entity (so the #[sea_orm(unique)] on the email field and the
email_verified: bool column are not created); add a new migration file (e.g.,
m20240101_create_users.rs) under apps/backend/migration/src/ that creates the
users table with a unique email column and a boolean email_verified column (plus
any other columns present in the users entity), and register that migration in
the migrations() function in apps/backend/migration/src/lib.rs so it returns a
vec! containing the new migration module; ensure the migration’s up/down
functions reflect the schema (unique constraint on email and creation/removal of
email_verified) to prevent schema mismatch errors when handlers/auth.rs uses
Set(false) and reads email_verified.

In `@apps/backend/src/handlers/auth.rs`:
- Around line 121-146: The current flow persists the user via
users::Entity::insert then performs email_verification::store_token and
send_verification_email, causing inconsistent state if Redis/SMTP fail; change
this by either (preferred) writing an outbox entry (e.g., create an Outbox
entity record in the same DB transaction alongside users::Entity::insert) and
dispatching email/redis work asynchronously from the outbox worker, or (minimal)
implement compensating cleanup: if email_verification::store_token or
send_verification_email returns an error, delete the created user (undo
users::Entity::insert) and return a proper error mapping instead of leaving a
half-created user; update error handling around users::Entity::insert,
email_verification::store_token, and send_verification_email accordingly so
state remains consistent.
- Around line 292-297: The build_verify_url function embeds the raw token into
the query string, which can break links if the token contains reserved
characters; update build_verify_url to percent-encode the token before
interpolation (e.g., use a URL-encoding helper such as url::form_urlencoded or
Url::parse + append_pair) and build the final URL from the trimmed
settings.email_verification_app_url plus the encoded token so the query is
always safe and correct.

In `@apps/backend/src/settings.rs`:
- Around line 17-27: The field email_verification_app_url is currently given a
default via serde(default = "default_email_verification_app_url") which will
silently fall back to "http://localhost:3000"; remove the default so the config
deserialization fails when that key is missing (make the struct field required),
delete or stop using default_email_verification_app_url()/default_allow_origin()
for this field, and ensure any callers that relied on the default now require
the explicit setting at startup so the process fails fast if
email_verification_app_url is not provided.

In `@apps/backend/src/utils/db.rs`:
- Around line 6-12: Replace the brittle string-based check in
is_postgres_unique_violation by using DbErr::sql_err() and matching the
structured SQL error; specifically, call err.sql_err(), if Some, match against
sea_orm::error::SqlErr::UniqueConstraintViolation(_) and return true for that
branch and false otherwise, falling back to false when sql_err() is None,
instead of using err.to_string() and substring checks.

In `@apps/backend/src/utils/email_verification.rs`:
- Around line 29-60: The current sequence using redis::cmd to GET old_token, DEL
old token, SET token_key and SET user_key is non-atomic and can leave multiple
valid tokens during concurrent requests; replace these multi-command ops with a
single Redis Lua script (use redis::Script or EVAL via the redis client) that:
reads the existing value of user_key, if present deletes the corresponding
KEY_TOKEN..old_token, then sets KEY_TOKEN..token to user_id with EX
TOKEN_TTL_SECS and sets user_key to token with EX TOKEN_TTL_SECS, and returns
success/failure; invoke this script in place of the code manipulating old_token,
token_key, KEY_TOKEN, TOKEN_TTL_SECS and propagate errors via the same
anyhow::anyhow! handling so error messages still include context.

Inline comments:
In `@apps/backend/src/utils/verification_email_outbox.rs`:
- Around line 61-70: run_worker currently sleeps before the first work cycle
causing up to a 30s startup delay; change the loop so the initial iteration runs
process_pending immediately (or set idle=false for the first loop) and only then
awaits POLL_INTERVAL_IDLE/POLL_INTERVAL_ACTIVE. Specifically, in run_worker
adjust the idle handling so process_pending() (or the function that handles
pending emails) is invoked before the first tokio::time::sleep, keeping the
existing idle flag logic and using POLL_INTERVAL_IDLE / POLL_INTERVAL_ACTIVE
unchanged for subsequent sleeps to preserve backoff behavior.
- Around line 52-58: process_pending currently selects rows with
status='Pending' without locking, so wake_worker and run_worker can pick the
same outbox row and cause duplicate processing; change process_pending to
atomically claim work by either using UPDATE ... WHERE status='Pending'
RETURNING (to flip status to 'Processing' and return claimed rows) or use SELECT
... FOR UPDATE SKIP LOCKED to fetch rows while preventing others from seeing
them, and ensure process_one only runs on claimed rows; also remove or move the
initial POLL_INTERVAL_IDLE sleep in run_worker so the worker polls immediately
on startup (or call process_pending once at startup) to avoid delayed backlog
processing.

In `@apps/frontend/app/utils/openapi.json`:
- Around line 244-250: OpenAPI responses for register, verify_email, and
resend_verification_email currently declare "text/plain" but the handlers return
Axum's Json<String> (application/json); update the response content media type
to "application/json" (keeping the schema as type: string) in the generated
openapi.json for those endpoints, or adjust the utoipa annotations for the
corresponding handlers (register, verify_email, resend_verification_email) so
the generated response content_type is application/json instead of text/plain.

237-252: ⚠️ Potential issue | 🟠 Major | ⚡ Quick win

ユーザー列挙攻撃が可能な状態になっています

レスポンスが 404 UserNotFound409 EmailAlreadyVerified200 成功 と分かれているため、攻撃者がメールアドレスの登録有無を特定できます。レートリミットもメールアドレス単位のため、異なるメールを連続して試行でき、列挙を抑止できません。

推奨対策: 存在しないユーザーや既に確認済みのユーザーに対しても、成功時と同一のレスポンス(200)を返すことでタイミングや応答コードによる情報漏洩を防ぎます。

- Around line 237-252: The handler leaks user existence via differing errors;
change the flow so both a non-existent user and an already-verified user produce
the same successful response (HTTP 200) and body as the genuine resend path:
still call email_verification::try_acquire_resend_slot(...) and perform
users::Entity::find(...).one(&state.db) and inspect user.email_verified to
decide whether to enqueue/send email, but do not return AuthError::UserNotFound
or AuthError::EmailAlreadyVerified — instead return the same success result for
those cases while logging internally if needed; keep returning
AuthError::TooManyRequests and internal errors unchanged so rate-limits and
failure modes remain enforced.

Inline comments:
In `@apps/backend/bruno/01-register-verify/01-register.bru`:
- Around line 25-30: The vars:pre-request block currently hardcodes baseUrl,
username, email, and password; remove those hardcoded entries and instead read
them from the shared environment file by referencing the environment variables
defined in environments/local.bru (baseUrl, email, password, username,
verificationToken) so the script uses the centralized environment values; update
any references in the 01-register.bru flow that assumed the inline vars to use
the environment variables instead.

In `@apps/backend/bruno/01-register-verify/02-verify-email.bru`:
- Around line 23-26: The pre-request block currently hardcodes verificationToken
(vars:pre-request { verificationToken: ... }), which overrides
environment/runtime values and causes expiry/mismatch failures; remove the
verificationToken entry from the pre-request vars so the flow uses the value
from environments/local.bru or the runtime-updated token, leaving baseUrl (and
other required entries) intact and ensuring verificationToken is set only in
environments/local.bru or updated at runtime.

In `@apps/backend/bruno/01-register-verify/03-login-unverified.bru`:
- Around line 24-27: Add a concrete test that asserts the unverified-login
behavior described in the docs: create or extend the tests block for
03-login-unverified.bru to perform the login request for an unverified email and
assert the HTTP status is 403 and the returned error code equals
"email-not-verified"; locate the test near the existing docs block in this file,
invoke the same login endpoint used by the scenario, and include assertions for
both the status and response error.code to ensure future regressions are caught.

In `@apps/backend/bruno/02-login/01-login.bru`:
- Around line 24-27: The vars:pre-request block currently hardcodes baseUrl and
email which must be moved to environment config; remove the hardcoded entries
from the vars:pre-request block in 01-login.bru and instead reference the
environment variables defined in environments/local.bru (ensure
environments/local.bru contains baseUrl, email, password, username,
verificationToken per guidelines), so the login scenario reads those variables
at runtime rather than using the fixed values.

In `@apps/backend/bruno/02-login/02-me.bru`:
- Around line 13-15: 現在の固定ヘッダ "Cookies: session=..." を削除し、正しいヘッダ名 "Cookie"
を使わないでください;代わりに Bruno の Cookie
管理を有効にして直前ログインで保存されたセッションCookieを再利用するように変更してください(固定の "session"
値を取り除き、リクエスト実行は同一コレクション内で順次実行して Cookie ストアが引き継がれるようにしてください)。

In `@apps/backend/bruno/environments/local.bru`:
- Around line 3-6: Replace the hardcoded/reused values in environments/local.bru
with explicit placeholders so re-runs don't collide: update the email, password,
username, and verificationToken entries to clearly indicate they must be filled
per-run (e.g., use "<your-unique-email@example.com>", "<your-password>",
"<your-username>", "<verification-token-from-email-or-apalis>"); ensure the keys
email, password, username, and verificationToken remain present but set to these
explicit placeholder strings so testers are forced to supply an unregistered
email and a valid verificationToken before running.

In `@apps/backend/Cargo.toml`:
- Around line 51-54: The apalis crate versions are inconsistent (apalis = rc.9
vs apalis-postgres/apalis-board = rc.8); update the Cargo.toml so the
apalis-family crates use the same RC (e.g., set apalis-postgres and apalis-board
to "1.0.0-rc.9" or pin apalis to "1.0.0-rc.8"), then run cargo update to
regenerate Cargo.lock and verify no duplicate resolutions; additionally check
apps/backend/migration/Cargo.lock to ensure it doesn't introduce a different
apalis RC and reconcile it if needed.

In `@apps/backend/src/entities/personal_tokens.rs`:
- Line 4: このファイルの不要なインポートを削除してください — 現在の行で宣言されている `use
crate::entities::scopes::Scope;` は `scopes`
フィールドを削除したため未使用になっています。該当インポートを取り除き、ビルド/コンパイル時の未使用警告を解消してください(参照箇所: `Scope`
インポート、`personal_tokens.rs` 内の `scopes` 関連コードが既に削除されていることを前提)。

In `@apps/backend/src/jobs/verification_email.rs`:
- Around line 65-73: The process function race allows an old retry job to
overwrite a newer token because process always calls
email_verification::store_token first; add a generation/issued_at field to
VerificationEmailJob (e.g., job.generation or job.issued_at) and change
email_verification::store_token to perform a conditional/atomic update that only
writes the token if the provided generation is strictly newer than the stored
one (use Redis compare-and-set/transaction or server-side check) so old jobs
cannot re-enable older tokens; update process to pass the new generation field
when calling store_token and ensure
verification_email_delivery::send_verification_email still receives the token
only after a successful conditional store.

In `@apps/backend/src/server.rs`:
- Around line 36-48: Extract the duplicated EnvFilter construction by first
computing the filter string once (e.g., let filter_str =
std::env::var("RUST_LOG").unwrap_or_else(|_| "info,sqlx=warn".into())), then
build a tracing_subscriber::EnvFilter from that value and reuse it in both
places (the TracingSubscriber::new(&broadcaster).layer().with_filter(...) that
produces board_tracing and the registry().with(...) call), using cloning if
necessary; update references to use the single env_filter variable instead of
creating EnvFilter twice.

In `@apps/backend/src/settings.rs`:
- Around line 25-27: The field verification_email_worker_concurrency currently
accepts 0 which can stop worker execution; add validation to ensure its value is
>= 1 during settings load/validation (e.g., in Settings::validate or
Settings::try_from after deserialization) and return a clear error (or panic on
invalid config) if it's < 1; reference the verification_email_worker_concurrency
field and the default_verification_email_worker_concurrency helper when
implementing the check so startup will fail fast when configuration is invalid.

local.bru の初期値を再実行しやすいプレースホルダにしてください。

email の固定値は再実行時に登録済み衝突を起こしやすく、verificationToken の空値は確認リクエスト失敗の原因になります。初期値は「毎回埋める前提」の明示的なプレースホルダにしておくのが安全です。

🔧 修正例
 vars {
   baseUrl: http://localhost:3400
-  email: test-user@example.com
+  email: your-unregistered-email@example.com
   password: password123
   username: testuser
-  verificationToken:
+  verificationToken: paste-token-from-email-or-apalis-board
 }

As per coding guidelines "Set required environment variables in environments/local.bru: baseUrl, email (unregistered), password, username, verificationToken (from email or Apalis Board)". Based on learnings, same-email retests can conflict unless changed or DB is reset.

Apalis 系の RC を揃えるか、Cargo.lock での解決(重複解決の有無)を確認

apps/backend/Cargo.lock では apalis = 1.0.0-rc.9apalis-postgres = 1.0.0-rc.8apalis-board = 1.0.0-rc.8 が解決されており、少なくとも同一クレート名としての apalis の重複解決は確認できませんでした。それでも rc.8 / rc.9 間の API 互換性で問題が出る可能性があるため、可能なら apalis-family の RC を揃えるか、apps/backend/migration/Cargo.lock 側でも同様に apalis が重複解決していないことを確認してください。

⚠️ Potential issue | 🟠 Major | 🏗️ Heavy lift

古いリトライジョブが新しい検証トークンを上書きできる競合があります。

process が毎回 store_token を先に実行するため、再送で新トークンが発行済みでも、失敗リトライ中の旧ジョブが後続実行されると旧トークンを再有効化し得ます。結果として最新リンクが無効化される競合が起きます。
ジョブに発行世代(例: issued_at/generation)を持たせ、store_token 側で「現在値より新しい世代のみ更新」を強制してください。

process function race allows an old retry job to overwrite a newer token because

job.issued_at) and change email_verification::store_token to perform a
conditional/atomic update that only writes the token if the provided generation
is strictly newer than the stored one (use Redis compare-and-set/transaction or
server-side check) so old jobs cannot re-enable older tokens; update process to
pass the new generation field when calling store_token and ensure
verification_email_delivery::send_verification_email still receives the token

メールアドレスの正規化が不十分です

resend_verification_email では trim() のみ適用していますが、register では正規化なしで保存しています。PostgreSQL のデフォルトでは大文字小文字を区別するため、User@Example.com で登録後に user@example.com で再送リクエストするとユーザーが見つからず 404 になります。

登録時と再送時の両方でメールアドレスを小文字に正規化することを検討してください。
