- Around line 127-129: Update the remember-me configuration around
komgaRememberMeServices and its SecurityFilterChain setup to enable
unconditional token issuance by setting alwaysRemember to true on the
TokenBasedRememberMeServices instance before it is passed to rememberMeServices.
Preserve the existing Komga Basic authentication and remember-me wiring.
In
`@backend/src/main/java/org/booklore/service/appsettings/AppSettingService.java`:
- Line 222: The Komga settings flow must reject invalid security values before
persistence and when loading existing rows. In
backend/src/main/java/org/booklore/service/appsettings/AppSettingService.java:222,
validate KOMGA_SETTINGS in updateSetting() and the loading path around
getJsonSetting before building settings; in
backend/src/main/java/org/booklore/model/dto/settings/KomgaSettings.java:13-14,
enforce non-null, non-blank keys and non-null, positive durations using the
existing validation approach. Add AppSettingServiceTest coverage in
backend/src/test/java/org/booklore/service/appsettings/AppSettingServiceTest.java:176-221
for null, blank, zero, and negative values.

**/*
⚙️ CodeRabbit configuration file
**/*: This project is being developed using current and future-facing technologies:
- Java 25 with --enable-preview (preview features are INTENTIONAL and encouraged)
- Spring Boot 4 (latest major version, check APIs accordingly)
- Jackson 3 (new package: tools.jackson.* instead of com.fasterxml.jackson.*)
- Hibernate 7.3.x (Jakarta Persistence 3.2, new APIs; avoid deprecated Hibernate 5/6 patterns)
- Angular 21 (signals-based reactivity, no NgModules unless legacy)
Grimmory Internal Tools
- epub4j and pdfium4j are our own internal tools developed by the Grimmory team.
- Always verify behavior and API changes against the upstream repositories:
- If you encounter issues with these libraries, check if a fix exists in the upstream grimmory-tools organization.
Metadata Standards and Compliance
- For all metadata writing and parsing logic, double-check against Dublin Core and ANSI standards to ensure perfect official compliance.
- We strictly follow the widespread and official XML-compliant methods for EPUB2, EPUB3, CBX, and PDF formats.
General Java and Spring rules
- ALWAYS prefer modern, idiomatic Java 25 constructs over legacy patterns.
- Preview features (--enable-preview) are enabled and intentional; do NOT flag them as risky unless there is a concrete runtime issue.
- Prefer: records, sealed classes/interfaces, pattern matching (switch expressions, instanceof), structured concurrency (StructuredTaskScope), scoped values, string templates, unnamed patterns/variables.
- Prefer virtual threads (Thread.ofVirtual(), Executors.newVirtualThreadPerTaskExecutor()) over platform threads for I/O-bound work.
- Prefer the new Sequenced Collections API (SequencedCollection, SequencedMap) where applicable.
- Prefer

Learning: When using Spring `ContentDisposition.builder(...).filename(name, StandardCharsets.UTF_8).build()` (i.e., explicitly providing UTF-8), the resulting header value should include both the quoted `filename="=?UTF-8?..."` and the RFC 5987 `filename*=` parameters. In this case, any extra ASCII fallback computation (e.g., deriving an ASCII `fallbackFilename` via `NON_ASCII_PATTERN` and calling `.filename(fallbackFilename)`) is likely redundant—prefer calling only `.filename(fallbackName?, StandardCharsets.UTF_8)` as appropriate and let Spring handle the UTF-8 header parameters. Verify by comparing the emitted header for `filename` and `filename*` before deciding to keep an ASCII fallback.

Learning: For this codebase (booklore-api), target Java 25 with `--enable-preview`, so `_` is intentionally used as an unnamed/ignored variable (e.g., lambda parameter or pattern variable) per Java’s preview feature JEP 456. Do not flag `_` in those contexts as an invalid/reserved identifier; only flag it if it’s used in a non-supported position (e.g., where an unnamed variable is not applicable for the Java preview rules).

Learning: When reviewing Java 23+ code, treat `java.time.Instant#until(Instant endExclusive)` as a valid API/method call (it returns a `Duration`, equivalent to `Duration.between(this, endExclusive)`). Do not flag `instant.until(otherInstant)` as a compile error or API misuse when the project targets Java 25+ (as in grimmory-tools/grimmory); the call should be considered correct and returns a `Duration`.

In Jackson 3, `jackson-annotations` intentionally remains under `com.fasterxml.jackson.annotation.*` for backward compatibility, while only the core processing packages (e.g., `jackson-core`, `jackson-databind`) move to the `tools.jackson.*` namespace.

Learning: In this codebase, do not raise review findings suggesting conversion of class-based DTOs to Java `record`s (e.g., DTOs under `org.booklore.model.dto.*` such as `org.booklore.model.dto.kobo`). Although records may be a preferred guideline in general, the team is intentionally avoiding new `record` DTOs right now due to low existing adoption—so class-based DTOs should not be flagged solely for not being records.

Learning: For this repository, reviewers should treat string truncation done via `String.length()` and `String.substring(0, maxLength)` (UTF-16 code units) as an accepted, consistent convention. Do not flag individual occurrences of this pattern as bugs, even though it is not code-point-aware for surrogate pairs. A separate global effort is already tracked to move toward code-point-aware truncation, so per-site fixes should be avoided during code review.

Learning: In this repo’s Java code, when catching Jsoup `org.jsoup.HttpStatusException` (and similar exceptions originating from external libraries) and wrapping/rethrowing them, do not require preserving the original exception stack trace (e.g., as flagged by PMD `PreserveStackTrace`) as long as the application already captures the actionable diagnostics in logs or the thrown exception message (such as HTTP status code and the requested URL). Reviewers should still ensure the log/message contains those details; the intent is to avoid noisy stack traces that only reflect external-library internals rather than application code.

Learning: In this codebase (grimmory-tools/grimmory), reviews should not treat inline `LIMIT`/`OFFSET` clauses inside `Query` JPQL/HQL strings as a JPA compliance risk. This is intentional: `hibernate.jpa.compliance.query=true` is intentionally not set, and Hibernate 7.3+ supports `LIMIT`/`OFFSET` as valid HQL extensions. Therefore, do not flag or require changes to `Query` annotations solely due to `LIMIT`/`OFFSET` usage.

Learning: In this repository’s JUnit 5 test sources (e.g., under backend/src/test/java/), do not flag “bare” `assert` statements as a bug. The project test runner is configured to always execute tests with assertions enabled (e.g., `-ea`), so `assert` behavior is consistent. Continue to review for correctness, but don’t treat unguarded `assert` usage in test classes as a static-analysis issue.

Only suppress the "no hardcoded paths" concern if the test does not perform any filesystem/network IO using that path (no reads/writes/Files.* calls or code paths that access the filesystem with that value); if the placeholder is actually used to touch the filesystem, flag it.

Learning: In grimmory-tools/grimmory unit/integration test classes (e.g., files matching **/*Test.java under backend/src/test/java/**), it is acceptable to directly instantiate Jackson mappers (e.g., `new ObjectMapper()` / `new JsonMapper(...)`) and this should NOT be flagged. The Jackson guidance to use Spring bean injection or `JsonMapper.shared()` applies only to production code; tests may construct dependencies directly as standard practice. Production-code mapper instantiation rules should still be enforced outside test sources.

Learning: For the Komga API remember-me configuration in `backend/src/main/java/org/booklore/config/security/SecurityConfig.java`, cookie issuance must remain controlled by the `remember-me` request parameter. Komelia sends `?remember-me=true` and receives the `komga-remember-me` cookie. Tachiyomi does not send the parameter and must not receive a remember-me cookie. Do not configure `TokenBasedRememberMeServices.setAlwaysRemember(true)`, because this must match real Komga behavior.

Learning: In `booklore-api/src/main/java/org/booklore/service/kobo/KoboInitializationService.java` and `booklore-api/src/main/java/org/booklore/model/dto/settings/KoboSettings.java`, the `forwardToKoboStore` field defaults to `false`. This means existing server installs that upgrade will have Kobo Store forwarding/combined init behavior silently disabled. This is **intentional by design** (per imnotjames, PR `#337`) and is expected to be communicated via release notes rather than through a migration/backfill.

Learning: In grimmory-tools/grimmory, when null-edge-case coverage is flagged for test files, the team preference is to prevent null paths at the service/production-code boundary (e.g., null guards or NonNull contracts) rather than adding boilerplate null-edge tests. Do not insist on null-edge tests when the developer confirms the null scenario cannot occur and intends to enforce that invariant in production code.

Learning: In `backend/src/test/java/org/booklore/service/KoboEntitlementServiceTest.java`, the entire test class uses JUnit-style assertions (`assertEquals`, `assertNull`, `assertNotNull`, `assertTrue`, `assertFalse`). Do not suggest migrating individual new tests to AssertJ style; consistency with the existing file is preferred over piecemeal migration.

Learning: When using Spring `ContentDisposition.builder(...).filename(name, StandardCharsets.UTF_8).build()` (i.e., explicitly providing UTF-8), the resulting header value should include both the quoted `filename="=?UTF-8?..."` and the RFC 5987 `filename*=` parameters. In this case, any extra ASCII fallback computation (e.g., deriving an ASCII `fallbackFilename` via `NON_ASCII_PATTERN` and calling `.filename(fallbackFilename)`) is likely redundant—prefer calling only `.filename(fallbackName?, StandardCharsets.UTF_8)` as appropriate and let Spring handle the UTF-8 header parameters. Verify by comparing the emitted header for `filename` and `filename*` before deciding to keep an ASCII fallback.

Learning: For this codebase (booklore-api), target Java 25 with `--enable-preview`, so `_` is intentionally used as an unnamed/ignored variable (e.g., lambda parameter or pattern variable) per Java’s preview feature JEP 456. Do not flag `_` in those contexts as an invalid/reserved identifier; only flag it if it’s used in a non-supported position (e.g., where an unnamed variable is not applicable for the Java preview rules).

Learning: When reviewing Java 23+ code, treat `java.time.Instant#until(Instant endExclusive)` as a valid API/method call (it returns a `Duration`, equivalent to `Duration.between(this, endExclusive)`). Do not flag `instant.until(otherInstant)` as a compile error or API misuse when the project targets Java 25+ (as in grimmory-tools/grimmory); the call should be considered correct and returns a `Duration`.

Learning: For this repository, reviewers should treat string truncation done via `String.length()` and `String.substring(0, maxLength)` (UTF-16 code units) as an accepted, consistent convention. Do not flag individual occurrences of this pattern as bugs, even though it is not code-point-aware for surrogate pairs. A separate global effort is already tracked to move toward code-point-aware truncation, so per-site fixes should be avoided during code review.

Learning: In this repo’s Java code, when catching Jsoup `org.jsoup.HttpStatusException` (and similar exceptions originating from external libraries) and wrapping/rethrowing them, do not require preserving the original exception stack trace (e.g., as flagged by PMD `PreserveStackTrace`) as long as the application already captures the actionable diagnostics in logs or the thrown exception message (such as HTTP status code and the requested URL). Reviewers should still ensure the log/message contains those details; the intent is to avoid noisy stack traces that only reflect external-library internals rather than application code.

During reviews, do not flag missing builder-level timeouts as a best-practice violation; rely on framework-level and/or HttpClient-level timeouts configured elsewhere for consistent behavior. Only raise an issue if you can verify that no effective timeout is configured at the HttpClient/framework level.

Therefore, do not flag or require changes to `Query` annotations solely due to `LIMIT`/`OFFSET` usage.

Learning: In grimmory-tools/grimmory unit/integration test classes (e.g., files matching **/*Test.java under backend/src/test/java/**), it is acceptable to directly instantiate Jackson mappers (e.g., `new ObjectMapper()` / `new JsonMapper(...)`) and this should NOT be flagged. The Jackson guidance to use Spring bean injection or `JsonMapper.shared()` applies only to production code; tests may construct dependencies directly as standard practice. Production-code mapper instantiation rules should still be enforced outside test sources.

The project test runner is configured to always execute tests with assertions enabled (e.g., `-ea`), so `assert` behavior is consistent.

Only suppress the "no hardcoded paths" concern if the test does not perform any filesystem/network IO using that path (no reads/writes/Files.* calls or code paths that access the filesystem with that value); if the placeholder is actually used to touch the filesystem, flag it.

Grimmory Internal Tools
- epub4j and pdfium4j are our own internal tools developed by the Grimmory team.
- Always verify behavior and API changes against the upstream repositories:
- If you encounter issues with these libraries, check if a fix exists in the upstream grimmory-tools organization.
Metadata Standards and Compliance
- For all metadata writing and parsing logic, double-check against Dublin Core and ANSI standards to ensure perfect official compliance.
- We strictly follow the widespread and official XML-compliant methods for EPUB2, EPUB3, CBX, and PDF formats.
General Java and Spring rules
- ALWAYS prefer modern, idiomatic Java 25 constructs over legacy patterns.
- Preview features (--enable-preview) are enabled and intentional; do NOT flag them as risky unless there is a concrete runtime issue.
- Prefer: records, sealed classes/interfaces, pattern matching (switch expressions, instanceof), structured concurrency (StructuredTaskScope), scoped values, string templates, unnamed patterns/variables.
- Prefer virtual threads (Thread.ofVirtual(), Executors.newVirtualThreadPerTaskExecutor()) over platform threads for I/O-bound work.
- Prefer the new Sequenced Collections API (SequencedCollection, SequencedMap) where applicable.
- Prefer

Learning: For the Komga API remember-me configuration in `backend/src/main/java/org/booklore/config/security/SecurityConfig.java`, cookie issuance must remain controlled by the `remember-me` request parameter. Komelia sends `?remember-me=true` and receives the `komga-remember-me` cookie. Tachiyomi does not send the parameter and must not receive a remember-me cookie. Do not configure `TokenBasedRememberMeServices.setAlwaysRemember(true)`, because this must match real Komga behavior.

Learning: In `booklore-api/src/main/java/org/booklore/service/kobo/KoboInitializationService.java` and `booklore-api/src/main/java/org/booklore/model/dto/settings/KoboSettings.java`, the `forwardToKoboStore` field defaults to `false`. This means existing server installs that upgrade will have Kobo Store forwarding/combined init behavior silently disabled. This is **intentional by design** (per imnotjames, PR `#337`) and is expected to be communicated via release notes rather than through a migration/backfill.

Learning: In grimmory-tools/grimmory, when null-edge-case coverage is flagged for test files, the team preference is to prevent null paths at the service/production-code boundary (e.g., null guards or NonNull contracts) rather than adding boilerplate null-edge tests. Do not insist on null-edge tests when the developer confirms the null scenario cannot occur and intends to enforce that invariant in production code.

Do not suggest migrating individual new tests to AssertJ style; consistency with the existing file is preferred over piecemeal migration.

Learning: In `grimmory-tools/grimmory`, CBX reader settings (including `CbxPageViewMode`, `CbxPageSplitOption`, `CbxScrollMode`, etc.) are stored as a raw JSON string blob in the `user_settings` table under a setting key (e.g., `CBX_READER_SETTING`). The backend does not deserialize these values into typed Java enum instances, so adding new frontend enum values (e.g., `TWO_PAGE_REVERSED`, `CbxPageSplitOption` members) does NOT cause Jackson `InvalidFormatException` errors. Do not flag frontend-only enum additions as backend serialization issues for these settings.

Learning: In the grimmory-tools/grimmory project's test classes (e.g., files matching **/*Test.java), direct instantiation of `new ObjectMapper()` (or any Jackson mapper) is acceptable and should NOT be flagged. The Jackson 3 guideline requiring injection as a Spring bean or use of `JsonMapper.shared()` applies only to production code, not to unit/integration test code where direct construction of dependencies is standard practice.

Learning: When using Spring `ContentDisposition.builder(...).filename(name, StandardCharsets.UTF_8).build()` (i.e., explicitly providing UTF-8), the resulting header value should include both the quoted `filename="=?UTF-8?..."` and the RFC 5987 `filename*=` parameters. In this case, any extra ASCII fallback computation (e.g., deriving an ASCII `fallbackFilename` via `NON_ASCII_PATTERN` and calling `.filename(fallbackFilename)`) is likely redundant—prefer calling only `.filename(fallbackName?, StandardCharsets.UTF_8)` as appropriate and let Spring handle the UTF-8 header parameters. Verify by comparing the emitted header for `filename` and `filename*` before deciding to keep an ASCII fallback.

Do not flag `_` in those contexts as an invalid/reserved identifier; only flag it if it’s used in a non-supported position (e.g., where an unnamed variable is not applicable for the Java preview rules).

Do not flag individual occurrences of this pattern as bugs, even though it is not code-point-aware for surrogate pairs. A separate global effort is already tracked to move toward code-point-aware truncation, so per-site fixes should be avoided during code review.

Learning: In this repo’s Java code, when catching Jsoup `org.jsoup.HttpStatusException` (and similar exceptions originating from external libraries) and wrapping/rethrowing them, do not require preserving the original exception stack trace (e.g., as flagged by PMD `PreserveStackTrace`) as long as the application already captures the actionable diagnostics in logs or the thrown exception message (such as HTTP status code and the requested URL). Reviewers should still ensure the log/message contains those details; the intent is to avoid noisy stack traces that only reflect external-library internals rather than application code.

Only raise an issue if you can verify that no effective timeout is configured at the HttpClient/framework level.

- Preview features (--enable-preview) are enabled and intentional; do NOT flag them as risky unless there is a concrete runtime issue.
- Prefer: records, sealed classes/interfaces, pattern matching (switch expressions, instanceof), structured concurrency (StructuredTaskScope), scoped values, string templates, unnamed patterns/variables.
- Prefer virtual threads (Thread.ofVirtual(), Executors.newVirtualThreadPerTaskExecutor()) over platform threads for I/O-bound work.
- Prefer the new Sequenced Collections API (SequencedCollection, SequencedMap) where applicable.
- Prefer

Learning: For the Komga API remember-me configuration in `backend/src/main/java/org/booklore/config/security/SecurityConfig.java`, cookie issuance must remain controlled by the `remember-me` request parameter. Komelia sends `?remember-me=true` and receives the `komga-remember-me` cookie. Tachiyomi does not send the parameter and must not receive a remember-me cookie. Do not configure `TokenBasedRememberMeServices.setAlwaysRemember(true)`, because this must match real Komga behavior.

Learning: In `booklore-api/src/main/java/org/booklore/service/kobo/KoboInitializationService.java` and `booklore-api/src/main/java/org/booklore/model/dto/settings/KoboSettings.java`, the `forwardToKoboStore` field defaults to `false`. This means existing server installs that upgrade will have Kobo Store forwarding/combined init behavior silently disabled. This is **intentional by design** (per imnotjames, PR `#337`) and is expected to be communicated via release notes rather than through a migration/backfill.

Learning: In grimmory-tools/grimmory, when null-edge-case coverage is flagged for test files, the team preference is to prevent null paths at the service/production-code boundary (e.g., null guards or NonNull contracts) rather than adding boilerplate null-edge tests. Do not insist on null-edge tests when the developer confirms the null scenario cannot occur and intends to enforce that invariant in production code.

Learning: In `backend/src/test/java/org/booklore/service/KoboEntitlementServiceTest.java`, the entire test class uses JUnit-style assertions (`assertEquals`, `assertNull`, `assertNotNull`, `assertTrue`, `assertFalse`). Do not suggest migrating individual new tests to AssertJ style; consistency with the existing file is preferred over piecemeal migration.

Learning: In `grimmory-tools/grimmory`, CBX reader settings (including `CbxPageViewMode`, `CbxPageSplitOption`, `CbxScrollMode`, etc.) are stored as a raw JSON string blob in the `user_settings` table under a setting key (e.g., `CBX_READER_SETTING`). The backend does not deserialize these values into typed Java enum instances, so adding new frontend enum values (e.g., `TWO_PAGE_REVERSED`, `CbxPageSplitOption` members) does NOT cause Jackson `InvalidFormatException` errors. Do not flag frontend-only enum additions as backend serialization issues for these settings.

Learning: In the grimmory-tools/grimmory project's test classes (e.g., files matching **/*Test.java), direct instantiation of `new ObjectMapper()` (or any Jackson mapper) is acceptable and should NOT be flagged. The Jackson 3 guideline requiring injection as a Spring bean or use of `JsonMapper.shared()` applies only to production code, not to unit/integration test code where direct construction of dependencies is standard practice.

Learning: When using Spring `ContentDisposition.builder(...).filename(name, StandardCharsets.UTF_8).build()` (i.e., explicitly providing UTF-8), the resulting header value should include both the quoted `filename="=?UTF-8?..."` and the RFC 5987 `filename*=` parameters. In this case, any extra ASCII fallback computation (e.g., deriving an ASCII `fallbackFilename` via `NON_ASCII_PATTERN` and calling `.filename(fallbackFilename)`) is likely redundant—prefer calling only `.filename(fallbackName?, StandardCharsets.UTF_8)` as appropriate and let Spring handle the UTF-8 header parameters. Verify by comparing the emitted header for `filename` and `filename*` before deciding to keep an ASCII fallback.

Learning: For this codebase (booklore-api), target Java 25 with `--enable-preview`, so `_` is intentionally used as an unnamed/ignored variable (e.g., lambda parameter or pattern variable) per Java’s preview feature JEP 456. Do not flag `_` in those contexts as an invalid/reserved identifier; only flag it if it’s used in a non-supported position (e.g., where an unnamed variable is not applicable for the Java preview rules).

Do not flag `instant.until(otherInstant)` as a compile error or API misuse when the project targets Java 25+ (as in grimmory-tools/grimmory); the call should be considered correct and returns a `Duration`.

Learning: For this repository, reviewers should treat string truncation done via `String.length()` and `String.substring(0, maxLength)` (UTF-16 code units) as an accepted, consistent convention. Do not flag individual occurrences of this pattern as bugs, even though it is not code-point-aware for surrogate pairs. A separate global effort is already tracked to move toward code-point-aware truncation, so per-site fixes should be avoided during code review.

Learning: In this repo’s Java code, when catching Jsoup `org.jsoup.HttpStatusException` (and similar exceptions originating from external libraries) and wrapping/rethrowing them, do not require preserving the original exception stack trace (e.g., as flagged by PMD `PreserveStackTrace`) as long as the application already captures the actionable diagnostics in logs or the thrown exception message (such as HTTP status code and the requested URL). Reviewers should still ensure the log/message contains those details; the intent is to avoid noisy stack traces that only reflect external-library internals rather than application code.

Learning: In this codebase (grimmory-tools/grimmory), it’s intentional to omit per-request timeouts on individual Java HttpRequest.Builder instances (e.g., GoodReadsParser.fetchJson). During reviews, do not flag missing builder-level timeouts as a best-practice violation; rely on framework-level and/or HttpClient-level timeouts configured elsewhere for consistent behavior. Only raise an issue if you can verify that no effective timeout is configured at the HttpClient/framework level.

Learning: In this codebase (grimmory-tools/grimmory), reviews should not treat inline `LIMIT`/`OFFSET` clauses inside `Query` JPQL/HQL strings as a JPA compliance risk. This is intentional: `hibernate.jpa.compliance.query=true` is intentionally not set, and Hibernate 7.3+ supports `LIMIT`/`OFFSET` as valid HQL extensions. Therefore, do not flag or require changes to `Query` annotations solely due to `LIMIT`/`OFFSET` usage.

Learning: In grimmory-tools/grimmory service-layer code, if arithmetic overflow occurs inside inference/business-logic (e.g., when deriving inferred fields like durationSeconds from start/end timestamps), treat it as a server-side anomaly. Prefer letting the global exception handler translate it into a generic 5xx response rather than throwing an explicit ApiError 4xx (e.g., do not convert overflow into a client error).

⚙️ CodeRabbit configuration file
**/*: This project is being developed using current and future-facing technologies:
- Java 25 with --enable-preview (preview features are INTENTIONAL and encouraged)
- Spring Boot 4 (latest major version, check APIs accordingly)
- Jackson 3 (new package: tools.jackson.* instead of com.fasterxml.jackson.*)
- Hibernate 7.3.x (Jakarta Persistence 3.2, new APIs; avoid deprecated Hibernate 5/6 patterns)
- Angular 21 (signals-based reactivity, no NgModules unless legacy)
Grimmory Internal Tools
- epub4j and pdfium4j are our own internal tools developed by the Grimmory team.
- Always verify behavior and API changes against the upstream repositories:
- If you encounter issues with these libraries, check if a fix exists in the upstream grimmory-tools organization.
Metadata Standards and Compliance
- For all metadata writing and parsing logic, double-check against Dublin Core and ANSI standards to ensure perfect official compliance.
- We strictly follow the widespread and official XML-compliant methods for EPUB2, EPUB3, CBX, and PDF formats.
General Java and Spring rules
- ALWAYS prefer modern, idiomatic Java 25 constructs over legacy patterns.
- Preview features (--enable-preview) are enabled and intentional; do NOT flag them as risky unless there is a concrete runtime issue.
- Prefer: records, sealed classes/interfaces, pattern matching (switch expressions, instanceof), structured concurrency (StructuredTaskScope), scoped values, string templates, unnamed patterns/variables.

Learning: For the Komga API remember-me configuration in `backend/src/main/java/org/booklore/config/security/SecurityConfig.java`, cookie issuance must remain controlled by the `remember-me` request parameter. Komelia sends `?remember-me=true` and receives the `komga-remember-me` cookie. Tachiyomi does not send the parameter and must not receive a remember-me cookie. Do not configure `TokenBasedRememberMeServices.setAlwaysRemember(true)`, because this must match real Komga behavior.

Learning: In `backend/src/test/java/org/booklore/service/KoboEntitlementServiceTest.java`, the entire test class uses JUnit-style assertions (`assertEquals`, `assertNull`, `assertNotNull`, `assertTrue`, `assertFalse`). Do not suggest migrating individual new tests to AssertJ style; consistency with the existing file is preferred over piecemeal migration.

Learning: In `backend/src/test/java/org/booklore/service/KoreaderServiceTest.java`, prefer the existing JUnit assertion style (such as `assertEquals`) over introducing AssertJ solely for new assertions, to maintain consistency within the test class.

Learning: In `backend/src/main/java/org/booklore/service/book/BookFileDetachmentService.java`, validating that `detachBookFile(...)` remains committed when `BookCoverService.regenerateCover(...)` fails requires integration coverage: both services are transactional, so a real cover-service exception can mark the shared Spring transaction rollback-only, which a Mockito-thrown exception cannot reproduce.

Learning: When using Spring `ContentDisposition.builder(...).filename(name, StandardCharsets.UTF_8).build()` (i.e., explicitly providing UTF-8), the resulting header value should include both the quoted `filename="=?UTF-8?..."` and the RFC 5987 `filename*=` parameters. In this case, any extra ASCII fallback computation (e.g., deriving an ASCII `fallbackFilename` via `NON_ASCII_PATTERN` and calling `.filename(fallbackFilename)`) is likely redundant—prefer calling only `.filename(fallbackName?, StandardCharsets.UTF_8)` as appropriate and let Spring handle the UTF-8 header parameters. Verify by comparing the emitted header for `filename` and `filename*` before deciding to keep an ASCII fallback.

Learning: For this codebase (booklore-api), target Java 25 with `--enable-preview`, so `_` is intentionally used as an unnamed/ignored variable (e.g., lambda parameter or pattern variable) per Java’s preview feature JEP 456. Do not flag `_` in those contexts as an invalid/reserved identifier; only flag it if it’s used in a non-supported position (e.g., where an unnamed variable is not applicable for the Java preview rules).

Learning: When reviewing Java 23+ code, treat `java.time.Instant#until(Instant endExclusive)` as a valid API/method call (it returns a `Duration`, equivalent to `Duration.between(this, endExclusive)`). Do not flag `instant.until(otherInstant)` as a compile error or API misuse when the project targets Java 25+ (as in grimmory-tools/grimmory); the call should be considered correct and returns a `Duration`.

Learning: For Jackson 3 codebases, do not treat imports from `com.fasterxml.jackson.annotation.*` (e.g., `JsonInclude`, `JsonProperty`, `JsonView`) as incorrect. In Jackson 3, `jackson-annotations` intentionally remains under `com.fasterxml.jackson.annotation.*` for backward compatibility, while only the core processing packages (e.g., `jackson-core`, `jackson-databind`) move to the `tools.jackson.*` namespace.

Learning: In this repository’s JUnit 5 test sources (e.g., under backend/src/test/java/), do not flag “bare” `assert` statements as a bug. The project test runner is configured to always execute tests with assertions enabled (e.g., `-ea`), so `assert` behavior is consistent. Continue to review for correctness, but don’t treat unguarded `assert` usage in test classes as a static-analysis issue.

Learning: In backend unit tests (Java files under backend/src/test/java), do not flag hardcoded placeholder filesystem paths (e.g., setting LibraryPathEntity.path = "/example") as violations when the value is intentionally unused for filesystem access. Only suppress the "no hardcoded paths" concern if the test does not perform any filesystem/network IO using that path (no reads/writes/Files.* calls or code paths that access the filesystem with that value); if the placeholder is actually used to touch the filesystem, flag it.

Learning: In grimmory-tools/grimmory unit/integration test classes (e.g., files matching **/*Test.java under backend/src/test/java/**), it is acceptable to directly instantiate Jackson mappers (e.g., `new ObjectMapper()` / `new JsonMapper(...)`) and this should NOT be flagged. The Jackson guidance to use Spring bean injection or `JsonMapper.shared()` applies only to production code; tests may construct dependencies directly as standard practice. Production-code mapper instantiation rules should still be enforced outside test sources.

Description
Adds remember-me authentication to the Komga API security chain, matching how real
Komga handles Komelia logins. Previously the chain was fully stateless and never
issued a cookie, so Komelia's post-login request for libraries (sent with no
credentials) got a 401 and showed "invalid credentials" even though login worked.
This change issues a signed
komga-remember-mecookie on login and enables sessionsupport (
JSESSIONID), so Komelia can talk to the API using cookies alone.Linked Issue
Refs #164 — implements the "Remember Me" authentication cookies checklist item.
Changes
KomgaSettingsDTO with a randomrememberMeKeygenerated on first boot andpersisted via the existing
KOMGA_SETTINGSkey, so it stays stable across restarts.komgaRememberMeServicesbean (TokenBasedRememberMeServices) in the Komgachain, cookie name
komga-remember-me(matches real Komga and Komelia's client).STATELESStoIF_REQUIRED, so theremember-me login creates a
JSESSIONIDthat Komelia replays. Basic auth(Tachiyomi/OPDS) is unchanged.
SettingPersistenceHelperandAppSettingService.AppSettingServiceTest(defaults persisted, persisted values readback, unique key generation).
Manual Testing Steps
Tested against a live instance on localhost:6060 with tcpdump on port 6060:
GET /komga/api/v2/users/me?remember-me=truewith Basic auth → 200 withSet-Cookie: komga-remember-me=...andSet-Cookie: JSESSIONID=...GET /komga/api/v1/librarieswith only those cookies (no Basic) → 200Screenshots (Optional)
Additional Context (Optional)
scanDirectoryExclusionsandoneshotsDirectory, which Komelia'sKomgaLibraryDTO requires (JsonConvertException). That's a different fix, not part of this auth
change.
via the settings API.
