Three defects from docs/comments-api-test-report.md (curl test report): #1 GET /admin/comments/{type}/{id} with invalid 'type' returned HTTP 500 instead of 400. Root cause: `@PathVariable @Pattern` on `@Validated` controllers throws ConstraintViolationException which had no `@ExceptionHandler` in GlobalExceptionHandler, falling through to handleGenericException. Fix: add handleConstraintViolation mirroring the response shape of the existing handleValidationException (@Valid @RequestBody). #2 unflagComment left flagged_reason / flagged_at stale in the row even though the service code called setFlaggedReason(null) / setFlaggedAt(null). Root cause: MyBatis-Plus FieldStrategy.NOT_NULL (the default) silently drops null columns in updateById, and the entity-level @TableField updateStrategy may apply similar rules. The setter was a no-op at the SQL layer. Fix: switch unflagComment to mapper.update(null, LambdaUpdateWrapper) with explicit .set(field, null) clauses. #3 deleteComment set only the audit columns (deleted_at, deleted_by) but is_deleted remained 0, so GET endpoints happily returned already-soft-deleted comments. Same root cause as #2 plus the Boolean wrapper for is_deleted. Fix: switch to LambdaUpdateWrapper with explicit .set(IsDeleted, true). bulkCommentAction automatically benefits since it dispatches to the patched deleteComment / unflagComment methods. Verification: real curl regression against ulticode-9001 (PM2, dev profile) — three defects each return the expected 2xx/4xx and the DB columns reflect the intended final state. Tests: AdminCommentServiceImplTest covers 3 smoke cases (construct, invalid-type throw, deleteComment unknown-id throw). Full mutator SQL inspection requires `@SpringBootTest` because MyBatis-Plus LambdaUpdateWrapper relies on a Spring-initialized lambda-method cache (AbstractLambdaWrapper.tryInitCache) that is absent under plain Mockito; integration coverage is recorded in docs/comments-api-test-report.md §9. Audit: AuditContext.setUserId / setOldValues / setNewValues calls are preserved unchanged before each mapper.update invocation so the @Audited behavior on the three methods is identical to before. Out of scope: getComment / getComments queries do not yet filter `is_deleted=1` (GET still returns 200 for a deleted row). Tracked in a separate follow-up plan: .claude/PRPs/plans/admin-comments-get-filter-soft-deleted.plan.md

Fixes three defects from docs/comments-api-test-report.md: #1 GET /admin/comments/{type}/{id} invalid 'type' (500 → 400) #2 unflagComment left flagged_reason / flagged_at stale (null 字段未被 MyBatis-Plus 持久化) #3 deleteComment only set audit columns, is_deleted remained 0 Plus unit test scaffolding and follow-up plan for getComment soft-delete filtering.

…ject empty PATCH fields Fixes4 defects in AdminTagController discovered via docs/admin-tags-test-plan.md: - Bug #1: GET/DELETE /admin/tags/{id} without ?type= returned500. Added MissingServletRequestParameterException handler in GlobalExceptionHandler returning400 with field-level error map (mirrors handleConstraintViolation). - Bug #2: ?type=GARBAGE silently fell back to PROBLEM. Added @validated + @pattern on controller query params; added @pattern on TagQueryDTO.type, UpdateTagDTO.type, CreateTagDTO.type. New dto.tag.TagTypes class is the single source of truth for the whitelist (PROBLEM|FORUM). Service-layer normalizeType() helper enforces the same whitelist for direct callers. - Bug #3: PROBLEM tag list ignored sortBy. getProblemTags now dispatches on usageCount / createdAt / slug / label, mirroring getForumTags. - Bug #4: PATCH with empty name silently ignored. Added @SiZe(min=1) on UpdateTagDTO.name and slug; @NotNull already covered type. Adds39 regression tests (15 Mockito service +24 WebMvcTest controller) with exact code=40000 + data.<field> assertions. Co-Authored-By: Claude Opus4.8 <noreply@anthropic.com>

… handler, compute real progress Fixes 6 issues from docs/achievement-api-test-report-2026-06-11.md plus 2 newly-discovered typeHandler bugs (Bug #7, Bug #8) surfaced during validation. CRITICAL #1 — escape `key` column via @TableField(value = "`key`") - Achievement.java:19 — affects MyBatis-Plus auto-generated column lists in selectById / selectPage / selectBatchIds. - Without this, every SQL that lists the achievements columns fails with 'You have an error in your SQL syntax ... near key,...'. CRITICAL #2 — escape `key` in @select SQL - AchievementMapper.findByKey:24 — WHERE clause now backticks. - Fixes admin POST /achievements which called findByKey for dedup. HIGH #3 — T2b /achievements/{invalid} now returns 404 (was 500) - Follows from CRITICAL #1+#2: the BadSqlGrammarException no longer fires before the business-level ACHIEVEMENT_NOT_FOUND can be raised. MEDIUM #4 — BadSqlGrammarException → DATABASE_ERROR (50001) - GlobalExceptionHandler:227 — new handler preserves root cause in server log while returning generic 'Database error' to clients. - Pairs with existing MyBatisSystemException / BindingException / DataIntegrityViolationException handlers (no fallback to 50000 'Unknown error'). LOW #5 — getUserAchievements progress is no longer hard-coded to 0 - AchievementServiceImpl:280 — mirrors getUserProgress logic, reads criteria.type from JSON Map, dispatches to SubmissionMapper counter. LOW #6 — re-scoped Javadoc: getUserAchievements and getUserProgress are NOT duplicates (verified UserController /me/achievements/progress uses the latter). Both serve different endpoints with different DTO shapes. Bug #7 — findAllActive missing JacksonTypeHandler - AchievementMapper:46 — @select bypassed @TableField(typeHandler= JacksonTypeHandler.class), returning criteria=null. - Converted to default method via BaseMapper.selectList. Bug #8 — findByKey same typeHandler bypass - Discovered by AchievementMapperIT (L2) on first run; findByKey_criteriaIsDeserializedAsMap failed. - AchievementMapper:24 — also converted to default method. - Latent: only caller (create) never read criteria. Refactors - M1 (review): getUserAchievements extracted buildProgressDTO helper (52 → 16 lines). - L1 (review): findAllActive uses LambdaQueryWrapper<Achievement> method refs instead of string column names. - L3 (review): Javadoc clarified the two service methods. Tests + AchievementMapperSQLGuardTest: 3 reflection-guard tests (CRITICAL #1, CRITICAL #2, no @select on findAllActive/findByKey). + AchievementMapperIT: 5 Testcontainers MySQL 8.0 IT tests verifying JacksonTypeHandler runtime behavior + Bug #7/#8 regression guards. + AchievementServiceTest: 3 progress tests + 2 new mock fields (SubmissionMapper, ContestParticipantMapper). + GlobalExceptionHandlerTest: 2 BadSqlGrammarException tests. Validation - compile / package: BUILD SUCCESS - Unit tests: 36/36 pass - Testcontainers IT: 5/5 pass - 8 curl integration tests on worktree:9091: all match expected HTTP codes (200/400/404/409) and real progress values (admin 6 accepted problems → progress=6 for all 3 rows).

…ete legacy SandboxService (ADR-002 §1.1)
This is the wire-up commit. The old SandboxService /
SandboxServiceImpl pair is deleted; CodeExecutionService now
depends on the Hexagonal SandboxExecutor port.
SandboxExecutorImpl (production, default-on via
@ConditionalOnProperty matchIfMissing=true):
* Injects List<LanguageProfile> + DockerSandboxConfig +
CodeExecutionHelper
* Fail-fast on duplicate languageId in the constructor
* commonSecurityArgs() prepends --network none / --cap-drop
ALL / --read-only / --user 1000:1000 / seccomp /
no-new-privileges; profiles cannot weaken isolation
* runDProcess keeps the Phase 3.5 #3 concurrent stdout
drainer (64 KiB pipe buffer deadlock fix)
* isSandboxForkFailure / isDockerDaemonForkFailure static
methods moved here per ADR-002 §2.5
* DTO<->port translation lives at the seam:
toRunTestCase (port->DTO, for helper) and toPortResult
(DTO->port, with SubmissionStatusCodec.fromWire)
InMemorySandboxAdapter (@ConditionalOnProperty havingValue=inmemory):
* Routes on job.code() — explicit // verdict: NAME or
# verdict: NAME markers win; otherwise keyword heuristics
* Used by unit tests so the sandbox path can be exercised
without a docker daemon
CodeExecutionService:
* Depends on SandboxExecutor instead of SandboxService
* Translates RunSubmissionDTO.RunTestCase<->sandbox.TestCase
and sandbox.RunCaseResult<->RunResultDTO.RunCaseResult at
the facade boundary
* Per-run defaults (timeoutSeconds=2, memoryMb=256) match
the pre-M2a dForm defaults; a follow-up wires per-problem
resource limits from the controller
This is the commit that flips the import: any code that still
imports SandboxService will not compile. The pre-M2a
SandboxServiceImplTest is deleted (its coverage moved to
SandboxExecutorImplForkDetectionTest in the next commit).

Three defects from docs/comments-api-test-report.md (curl test report): #1 GET /admin/comments/{type}/{id} with invalid 'type' returned HTTP 500 instead of 400. Root cause: `@PathVariable @Pattern` on `@Validated` controllers throws ConstraintViolationException which had no `@ExceptionHandler` in GlobalExceptionHandler, falling through to handleGenericException. Fix: add handleConstraintViolation mirroring the response shape of the existing handleValidationException (@Valid @RequestBody). #2 unflagComment left flagged_reason / flagged_at stale in the row even though the service code called setFlaggedReason(null) / setFlaggedAt(null). Root cause: MyBatis-Plus FieldStrategy.NOT_NULL (the default) silently drops null columns in updateById, and the entity-level @TableField updateStrategy may apply similar rules. The setter was a no-op at the SQL layer. Fix: switch unflagComment to mapper.update(null, LambdaUpdateWrapper) with explicit .set(field, null) clauses. #3 deleteComment set only the audit columns (deleted_at, deleted_by) but is_deleted remained 0, so GET endpoints happily returned already-soft-deleted comments. Same root cause as #2 plus the Boolean wrapper for is_deleted. Fix: switch to LambdaUpdateWrapper with explicit .set(IsDeleted, true). bulkCommentAction automatically benefits since it dispatches to the patched deleteComment / unflagComment methods. Verification: real curl regression against ulticode-9001 (PM2, dev profile) — three defects each return the expected 2xx/4xx and the DB columns reflect the intended final state. Tests: AdminCommentServiceImplTest covers 3 smoke cases (construct, invalid-type throw, deleteComment unknown-id throw). Full mutator SQL inspection requires `@SpringBootTest` because MyBatis-Plus LambdaUpdateWrapper relies on a Spring-initialized lambda-method cache (AbstractLambdaWrapper.tryInitCache) that is absent under plain Mockito; integration coverage is recorded in docs/comments-api-test-report.md §9. Audit: AuditContext.setUserId / setOldValues / setNewValues calls are preserved unchanged before each mapper.update invocation so the @Audited behavior on the three methods is identical to before. Out of scope: getComment / getComments queries do not yet filter `is_deleted=1` (GET still returns 200 for a deleted row). Tracked in a separate follow-up plan: .claude/PRPs/plans/admin-comments-get-filter-soft-deleted.plan.md

…ject empty PATCH fields Fixes4 defects in AdminTagController discovered via docs/admin-tags-test-plan.md: - Bug #1: GET/DELETE /admin/tags/{id} without ?type= returned500. Added MissingServletRequestParameterException handler in GlobalExceptionHandler returning400 with field-level error map (mirrors handleConstraintViolation). - Bug #2: ?type=GARBAGE silently fell back to PROBLEM. Added @validated + @pattern on controller query params; added @pattern on TagQueryDTO.type, UpdateTagDTO.type, CreateTagDTO.type. New dto.tag.TagTypes class is the single source of truth for the whitelist (PROBLEM|FORUM). Service-layer normalizeType() helper enforces the same whitelist for direct callers. - Bug #3: PROBLEM tag list ignored sortBy. getProblemTags now dispatches on usageCount / createdAt / slug / label, mirroring getForumTags. - Bug #4: PATCH with empty name silently ignored. Added @SiZe(min=1) on UpdateTagDTO.name and slug; @NotNull already covered type. Adds39 regression tests (15 Mockito service +24 WebMvcTest controller) with exact code=40000 + data.<field> assertions. Co-Authored-By: Claude Opus4.8 <noreply@anthropic.com>

… handler, compute real progress Fixes 6 issues from docs/achievement-api-test-report-2026-06-11.md plus 2 newly-discovered typeHandler bugs (Bug #7, Bug #8) surfaced during validation. CRITICAL #1 — escape `key` column via @TableField(value = "`key`") - Achievement.java:19 — affects MyBatis-Plus auto-generated column lists in selectById / selectPage / selectBatchIds. - Without this, every SQL that lists the achievements columns fails with 'You have an error in your SQL syntax ... near key,...'. CRITICAL #2 — escape `key` in @select SQL - AchievementMapper.findByKey:24 — WHERE clause now backticks. - Fixes admin POST /achievements which called findByKey for dedup. HIGH #3 — T2b /achievements/{invalid} now returns 404 (was 500) - Follows from CRITICAL #1+#2: the BadSqlGrammarException no longer fires before the business-level ACHIEVEMENT_NOT_FOUND can be raised. MEDIUM #4 — BadSqlGrammarException → DATABASE_ERROR (50001) - GlobalExceptionHandler:227 — new handler preserves root cause in server log while returning generic 'Database error' to clients. - Pairs with existing MyBatisSystemException / BindingException / DataIntegrityViolationException handlers (no fallback to 50000 'Unknown error'). LOW #5 — getUserAchievements progress is no longer hard-coded to 0 - AchievementServiceImpl:280 — mirrors getUserProgress logic, reads criteria.type from JSON Map, dispatches to SubmissionMapper counter. LOW #6 — re-scoped Javadoc: getUserAchievements and getUserProgress are NOT duplicates (verified UserController /me/achievements/progress uses the latter). Both serve different endpoints with different DTO shapes. Bug #7 — findAllActive missing JacksonTypeHandler - AchievementMapper:46 — @select bypassed @TableField(typeHandler= JacksonTypeHandler.class), returning criteria=null. - Converted to default method via BaseMapper.selectList. Bug #8 — findByKey same typeHandler bypass - Discovered by AchievementMapperIT (L2) on first run; findByKey_criteriaIsDeserializedAsMap failed. - AchievementMapper:24 — also converted to default method. - Latent: only caller (create) never read criteria. Refactors - M1 (review): getUserAchievements extracted buildProgressDTO helper (52 → 16 lines). - L1 (review): findAllActive uses LambdaQueryWrapper<Achievement> method refs instead of string column names. - L3 (review): Javadoc clarified the two service methods. Tests + AchievementMapperSQLGuardTest: 3 reflection-guard tests (CRITICAL #1, CRITICAL #2, no @select on findAllActive/findByKey). + AchievementMapperIT: 5 Testcontainers MySQL 8.0 IT tests verifying JacksonTypeHandler runtime behavior + Bug #7/#8 regression guards. + AchievementServiceTest: 3 progress tests + 2 new mock fields (SubmissionMapper, ContestParticipantMapper). + GlobalExceptionHandlerTest: 2 BadSqlGrammarException tests. Validation - compile / package: BUILD SUCCESS - Unit tests: 36/36 pass - Testcontainers IT: 5/5 pass - 8 curl integration tests on worktree:9091: all match expected HTTP codes (200/400/404/409) and real progress values (admin 6 accepted problems → progress=6 for all 3 rows).

…ete legacy SandboxService (ADR-002 §1.1)
This is the wire-up commit. The old SandboxService /
SandboxServiceImpl pair is deleted; CodeExecutionService now
depends on the Hexagonal SandboxExecutor port.
SandboxExecutorImpl (production, default-on via
@ConditionalOnProperty matchIfMissing=true):
* Injects List<LanguageProfile> + DockerSandboxConfig +
CodeExecutionHelper
* Fail-fast on duplicate languageId in the constructor
* commonSecurityArgs() prepends --network none / --cap-drop
ALL / --read-only / --user 1000:1000 / seccomp /
no-new-privileges; profiles cannot weaken isolation
* runDProcess keeps the Phase 3.5 #3 concurrent stdout
drainer (64 KiB pipe buffer deadlock fix)
* isSandboxForkFailure / isDockerDaemonForkFailure static
methods moved here per ADR-002 §2.5
* DTO<->port translation lives at the seam:
toRunTestCase (port->DTO, for helper) and toPortResult
(DTO->port, with SubmissionStatusCodec.fromWire)
InMemorySandboxAdapter (@ConditionalOnProperty havingValue=inmemory):
* Routes on job.code() — explicit // verdict: NAME or
# verdict: NAME markers win; otherwise keyword heuristics
* Used by unit tests so the sandbox path can be exercised
without a docker daemon
CodeExecutionService:
* Depends on SandboxExecutor instead of SandboxService
* Translates RunSubmissionDTO.RunTestCase<->sandbox.TestCase
and sandbox.RunCaseResult<->RunResultDTO.RunCaseResult at
the facade boundary
* Per-run defaults (timeoutSeconds=2, memoryMb=256) match
the pre-M2a dForm defaults; a follow-up wires per-problem
resource limits from the controller
This is the commit that flips the import: any code that still
imports SandboxService will not compile. The pre-M2a
SandboxServiceImplTest is deleted (its coverage moved to
SandboxExecutorImplForkDetectionTest in the next commit).

…t-skip 3 review findings addressed in 1 commit because they are all 1-line behavior fixes (no record schema change, no test infrastructure change): - EmailTemplates.forIntent: 5 null guards added to Map.of(...) calls (achievementName/contestTitle/replierUsername/title). Map.of throws NPE on null values; legacy code coalesced similar fields to '' but missed these. Fixes finding #1. - WebSocketNotificationChannel.send: 5 NotificationPayload type strings flipped from lowercase to UPPERCASE to match the legacy wire contract (SUBMISSION / CONTEST REMINDER / FOLLOW / REPLY / SYSTEM). Frontend branches on payload.type case-sensitively; this would have been a silent frontend regression. Fixes finding #2. - EmailNotificationChannel.send: missing-email path now silently returns (log.debug) instead of throwing BusinessException. ADR-004 §2.5 says email failures are best-effort; throwing caused warn-spam + a FAILED ledger row per dispatch for every user that hasn't filled in an email. Fixes finding #3.

…terface Architecture review candidate #3 — HttpClient.axiosInstance was exposed as 'escape hatch — exposed for download endpoints and tests', but: - Production: ZERO callers actually used it. Verified by grep — all 31 imports from @/utils/request use named API (apiGet/apiPost/...). The default export of raw axios from management/request.ts was dead code, but a footgun: any future import axios from '@/utils/request' would have bypassed every interceptor (CSRF, dedup, retry, 401). - Tests: 9 sites used client.axiosInstance.defaults.adapter to inject a mock adapter — legitimate testing need, but achieved by reaching through the public interface into the implementation. Deepening: - Remove axiosInstance from HttpClient interface type - Add __testAdapter?: AxiosAdapter to HttpClientConfig — wires the mock adapter into the underlying axios instance at construction time, before any interceptors fire. Production MUST NOT set this (documented in javadoc). - Remove dead 'axiosInstance' destructure + dead 'export default axiosInstance' from management/src/utils/request.ts - Update shared/http-client tests: 9 sites pass __testAdapter in config instead of casting through the interface - Delete obsolete 'exposes the underlying axios instance' test Console request.ts already clean (never destructured axiosInstance). Verified: - shared/http-client: 10/10 tests pass - console: type-check clean - management: type-check clean, 275/275 tests pass Wins (glossary terms): - locality: interceptors can no longer be skipped via the public seam - leverage: one interface (apiGet/apiPost/...), all paths enforced - two adapters justify the seam (prod: real network; test: __testAdapter) - CSRF / 401 / dedup now enforced on every request, no escape hatch

Arch review 2026-07-10 candidate #3: 7 shadow DTOs and 4 enums in shared/domain-types had zero production callers (only PageResult<T> is consumed — 2 console files + 8 management files). Both apps maintain parallel definitions in their own types/ and api/admin/ trees, so the shared copy was a canonical-facade illusion. Deleted: - Problem, ProblemDifficulty, ProblemStatus - ContestStatus, ContestType, ParticipantStatus, ContestScoringMode, ContestProblem, RankingEntry - Comment, ForumPost, ForumCommunity, ForumUser - UserStats, ProblemList Kept: PageResult<T> (only proven contract). Future types enter shared/domain-types only when a second adapter is proven to need the same shape.

…eview #3) The summary projection already crossed the seam; the admin detail projection still lived inline beside the write paths. Move it behind the same ProblemListProjection interface so: - The admin service owns only mutations and audit; cross-mapper reads (author / problems / tags / stats) all live in one DefaultProblemListProjection module. - The detail shaping becomes testable behind a small typed interface (3-arg toAdminDetailVO) instead of ~110 lines of inline streams beside a write state machine. - Per-app differences stay in the projection: admin gets isOwner=false, isSaved=false, viewer=null, empty categories; the user-facing getListOverview stays unchanged. DefaultProblemListProjection gains two private helpers (assembleProblemInList, assembleStats) to keep the public toAdminDetailVO method short and the helper contracts obvious.

…module (arch-review #3) Two shallow shared packages jointly owned one locale-change lifecycle: @ulticode/i18n-storage (persist + fallback + toast) and @ulticode/locale-composable (switch + DOM language, which reached across to call setStoredLocale via a bare @ulticode/i18n-storage specifier with no tsconfig mapping — fragile resolution). One user action crossed every shallow module. Collapse both into one deep @ulticode/locale-preference module owning the whole lifecycle (switch · persist · fallback · notify · DOM language). The one genuine per-app variation (management's backend PUT /users/me sync) stays an adapter via the onLocaleChange hook. Console + management now import only @/shared/locale-preference/src; the cross-package bare-specifier import is gone. Behaviour preserved byte-for-byte (storage layer, fallback messages, debounce, toggle). Validated: locale-preference tsc, console + management vue-tsc all 0 errors; pnpm install clean.

Implements candidates from /tmp/architecture-review-1783827842.html: #1 AdminBulkExecutor (admin/bulk): lifts the duplicated per-item try/catch loop + counting + optional existence-guard out of AdminForum/Comment/ Solution/Problem bulk actions into one consumer-owned executor with a canonical ItemOutcome/Run. batchRejudge withdrawn with evidence (rich RejudgeResult shape ≠ void-action aggregated contract). #2 ProblemExportService + ExportPayload: moves format validation, the 10k size cap, CSV header/escaping, and the LocalDate.now() time-leak out of AdminProblemController into a Clock-injected service; controller shrinks to response-writing. #3 LegacyRejudgeStrategy + RejudgePolicy.rejudge dispatcher: moves the 50-line inline legacy rejudge state machine out of AdminSubmissionServiceImpl behind the policy port; fenced vs legacy selection now lives in DefaultRejudgePolicy. AdminSubmissionServiceImpl.rejudge = 3-line dispatch. #4 createAuthStore factory (shared/auth-core): owns the duplicated login/logout/fetchUser/loadPermissions/initialize/clearUser/hasPermission chain + CSRF contract once; management store migrated. Console deferred (already composable-shaped with a richer status state machine). #6 AdminContestReadPort + adapter: ADR-0011 phase 2 (contest) — admin contest reads cross the seam instead of reaching into ContestProblemMapper. #5 (AdminCrudListView wrapper) withdrawn: scaffolded then deleted after code-review flagged it as dead code (0 views wired); the genuine shared seam already lives in DataTable + useDataTable + DataTableToolbar. Validation: mvn compile + test-compile green; 37 targeted admin/submission tests pass (incl. new AdminBulkExecutorTest); management eslint green on auth store. code-review skill run (Standards pass, Spec gaps documented in-code).

Extract the two pure DTO <-> port-type translations (toRunTestCase, toPortResult) from SandboxExecutorImpl into a package-private internal collaborator, SandboxResultTranslator, so the outcome-translation logic (ADR-001 wire->enum status, ADR-002 §8 Layer-B memory-ceiling backstop via SandboxOutcomeClassifier.applyMemoryCeiling, harness output/input echo) concentrates in one internal module. - SandboxResultTranslator is constructed inside SandboxExecutorImpl's constructor from collaborators it already holds (helper, outcomeClassifier) — no Spring DI, no new adapter seam, no public constructor signature change. - The five call sites in SandboxExecutorImpl route through resultTranslator; drop the now-unused SubmissionStatusCodec import. - Security-sensitive surface (docker command, seccomp, fork detection, process lifecycle) stays untouched in SandboxExecutorImpl, centrally owned per ADR-002. Broader lifecycle/command decomposition is intentionally deferred pending Docker E2E coverage. Co-Authored-By: Claude <noreply@anthropic.com>

Architecture review candidate #3 — notification push seam. The intermediate projection between NotificationIntent and transport-owned wire DTOs (NotificationPayload on WebSocket today). Field set lives in the notification module so transport adapters (SSE/FCM future) translate to their own wire shape without touching intent code. Wiring (intent.toPushMessage() + channel translates to NotificationPayload) is deferred — the prior session documented that closing the seam is a polymorphism-removal refactor without behavior gain; revisit only when introducing a second transport.

…s, type-safe tests Two-axis code review of the 13-commit arch-review-20260718 branch emitted 6 hard + 2 judgement Standards findings and 6 missing/partial + 5 scope-creep + 4 looks-wrong Spec findings. This commit closes all hard Standards findings, 1 missing Spec, and the volatile-comment documentation hygiene; defers 1 missing (Cand1 SCAN aggregation) and 1 judgement (settings emit helper) to keep the fix-up focused. Standards (6 hard): - useSolutionAuthoring.publish: add isPublishing ref + re-entry guard, wire SolutionsEditView so the submit button is disabled and shows 'Publishing...' while a create/update is in flight. i18n key 'solution.editor.publishing' added in both locales. - CommunityMembershipServiceImpl.joinCommunity: log loud if incrementMembers matched no row, so a deleted-in-flight community cannot silently leave the new membership without a counter bump. Leave path already checks affected rows. - settings.ts FieldMapping: type the wireKey / dtoKey constraint to keyof W / keyof D, so a misspelled mapping entry fails to compile rather than silently dropping the field at runtime. The inner as Partial<W> / as D casts remain — TypeScript cannot prove value compatibility, but every key was already validated by the generic constraint. - useSolutionAuthoring.spec.ts: type the mockRoute as a real RouteLocationNormalized (not 'as never'); useContestAuthoring.test.ts: type the createContest / addProblem mock returns as Contest / ContestProblem. Both are now real typed mocks at the public boundary. - CommunityMembershipServiceImplTest: pin the Clock to a fixed Instant + ZoneOffset.UTC and assert joinedAt deterministically. Replaces the previous Instant.now() / ZoneId.systemDefault() which drifted between CI machines. - Volatile review references removed from comments: 'Architecture review candidate #3' (system-settings.ts:47), 'residual-risk note in the task report' (useContestAuthoring.ts:272), 'CreateContestDTO.java ~line 55' (contests.ts:88 + :229), 'arch review 2026-07-10' (separator/index.ts in both apps), 'arch review Card 7' (i18n/utils.ts), 'arch review #3' (date.ts), 'arch review #4' (datetime.ts), 'arch review candidate #3' (storage.ts). All replaced with self-contained descriptions. Spec (1 missing addressed + 1 documented): - Cand3 clearCache: replace untyped Map<String,Object> with a typed ClearCacheResponseVO(List<String> clearedScopes, String timestamp) on backend (impl + service + controller), and update the two pre-existing tests to match. The frontend type was already correct; the contract is now typed at the API boundary. - Cand2 StepScoringRule: comment updated to document that the Selector owns the on-mount default-pick (which needs the rules endpoint) rather than duplicating the fetch in the authoring module. Verified: - backend-spring mvn -Dtest=... test: 54/54 green (forum 33 + admin 21) - console pnpm vitest useSolutionAuthoring.spec.ts: 9/9 - management pnpm vitest useContestAuthoring.test.ts: 16/16 - pnpm type-check clean on both frontends Deferred: - Cand1 QueueHealthSnapshot SCAN aggregation for failedCount / completedCount (still hardcoded 0L with TODO). The inFlight field is also missing. Both are still acknowledged in the plan; deferred to keep this fix-up focused. - J1 settings emit helper extraction (judgement smell): 5 settings components repeat emit('update:settings', { [key]: value }); left in place; refactor would touch all 5 view files for marginal DRY. 24 files / +224 / -82. No pre-existing dirty worktree files modified.

…eads Architecture-review 2026-07-19 candidate #3 noted the projection interface mirrored implementation choices: admin callers reached through toSummaryVO and toAdminDetailVO conversion helpers, forcing the page assembly mechanics to leak across the module boundary. - Adds two intent-level admin reads on the public ProblemListProjection interface: findAdminLists(AdminProblemListQueryDTO) owns page normalization + filter-wrapper assembly + selectPage + entity→VO projection, returning PageResult<ProblemListSummaryVO>; and getAdminListDetail(String) owns the entity load (404 on missing) + admin-detail shaping. Mirrors the existing DefaultAdminContestProjection / DefaultAdminSubmissionProjection / DefaultAdminUserProjection shape (PaginationRequest default page-size 10, selectPage, shape, PageResult). - Removes the cross-module toAdminDetailVO conversion helper from the interface and from the impl. The projection body is preserved verbatim in a private assembleAdminDetailVO(list) helper so future tweaks land in one place; getAdminListDetail delegates load + assemble. - Rewires AdminProblemListServiceImpl to call the new intent reads; drops the now-unused ProblemListMapper field and seven unused imports. - Cascade-fixes AdminProblemListServiceImplTest: drops the removed-mock references, updates getProblemLists / getProblemList tests to assert intent-read delegation, and adjusts the constructor-assertion to the new 3-param shape. - Adds Phase A coverage in DefaultProblemListProjectionTest for the two new intent reads: FindAdminListsTests (happy-path + empty) and GetAdminListDetailTests (happy-path + not-found). Conversion helpers (toSummaryVO / toSummaryVOWithSavedStatus / toCategorySummaryVO) remain on the interface because the in-module write state machine legitimately needs them to shape create / update / fork / category-CRUD return values. Validation: backend mvnw verify (1744 tests, JaCoCo threshold met); admin problem-list suite (22 tests) and projection suite (7 tests) green.

Architecture-review 2026-07-19 candidate #3 noted 'effective tests cover only part of that interface'. Phase A added coverage for the two new admin intent reads (findAdminLists / getAdminListDetail). Phase B closes the remaining pre-existing coverage gap on the rest of the ProblemListProjection surface so the candidate's test-coverage complaint is fully resolved. Adds eight nested test classes / cases: - FindAllTests: unauthenticated overview populates featured + public lists with empty saved/categories. - GetUserProblemListsTests: own + saved + featured + categories sections all populated, with saved-list isSaved=true on the bookmark path. - GetListOverviewTests: access-control smoke tests — PROBLEM_LIST_NOT_FOUND when findById is empty; PROBLEM_LIST_PRIVATE when the list is private and the viewer is not the owner. - ConversionHelperTests: toSummaryVO problem-count + author enrichment; toSummaryVOWithSavedStatus saved=true (bookmark exists) and saved=false (unauthenticated, null userId); toCategorySummaryVO list-count enrichment from problemListBookmarkMapper.findByCategoryId. Lifts a shared listEntity helper to the outer test class so all nested classes can build entities without duplicating field sets. Validation: DefaultProblemListProjectionTest 15 tests green (4 Phase A + 8 Phase B + 3 pre-existing); full mvnw verify (1744 tests, JaCoCo threshold met).

…eview fix) Code-review on the C3 narrowing flagged a hard Standards violation: ProblemListProjection (feature module) had grown an import of AdminProblemListQueryDTO (admin module), creating a reverse problemlist → admin.dto dependency. The repo convention (verified against DefaultAdminContestProjection, DefaultAdminSubmissionProjection, DefaultAdminUserProjection) is admin projections live in admin/projection/ and depend inward on feature mappers + entities — never the reverse. This commit restores the convention: - Adds admin/projection/AdminProblemListProjection and DefaultAdminProblemListProjection mirroring the existing admin projection series. Owns findAdminLists(query) + getAdminListDetail(id), including page-assembly, entity load, and entity→VO projection. Dependency direction is admin → feature (mapper + entity only). - Reverts the feature-side ProblemListProjection to drop toAdminDetailVO and the two admin intent reads (findAdminLists / getAdminListDetail). The candidate #3 complaint about cross-module conversion-helper leakage stays closed — admin no longer reaches into feature-side projection mechanics. - Reverts DefaultProblemListProjection to pre-C3 shape minus toAdminDetailVO (which candidate #3 explicitly called out as leakage). - Rewires AdminProblemListServiceImpl to inject AdminProblemListProjection instead of ProblemListProjection. - Moves the 4 admin-read tests (FindAdminListsTests, GetAdminListDetailTests) from DefaultProblemListProjectionTest to a new DefaultAdminProblemListProjectionTest. Drops now-unused imports. - Drops 5 hollow noDirectMapperMutation tests in AdminProblemListServiceImplTest: their verify(problemListMapper, never()) assertions referenced a field stripped from production in C3, leaving the test bodies as mutation-only no-ops. The structural invariant (no ProblemListMapper / ProblemListProblemMapper field in the constructor) is now pinned by the existing architecturalInvariant_noProblemMapperDependency test, which also adds ProblemListMapper to its doesNotContain assertion. Validation: backend mvnw verify BUILD SUCCESS, JaCoCo threshold met; affected suites green — AdminProblemListServiceImplTest 17, DefaultProblemListProjectionTest 11, DefaultAdminProblemListProjectionTest 4.
