Architecture & CQRS services/identity-service/src/main/java/com/tickon/identity/.../command/.../*, services/identity-service/src/main/java/com/tickon/identity/.../query/.../*, services/identity-service/src/main/java/com/tickon/identity/contracts/*, docs/agent/ARCHITECTURE.md |
Introduces command/query types and handlers, removes many UseCase interfaces/DTOs, adds internal com.tickon.identity.contracts package and updates architecture docs to CQRS/CommandBus+QueryBus. |
Ports / Bus / Observability services/identity-service/src/main/java/com/tickon/identity/.../ports/*, services/identity-service/src/main/java/com/tickon/identity/shared/platform/bus/*, services/identity-service/src/main/java/com/tickon/identity/shared/platform/bus/Observable*.java, services/identity-service/src/main/java/com/tickon/identity/shared/platform/metrics/IdentityMetrics.java |
Reorganizes ports (moves .out -> parent), adds TokenProvider/EmailSender/PasswordHasher interfaces, introduces SpringCommandBus/SpringQueryBus and observable decorators with metrics and tests; IdentityMetrics API changed to void-increment style. |
Domain & Types Migration services/identity-service/src/main/java/com/tickon/identity/*/domain/*, common/src/main/java/com/tickon/common/identity/domain/valueobjects/* |
Moves Email/UserId/PasswordHash/UserStatus into identity-service user domain; replaces many UserId/Email value-object usages with UUID/String; updates domain events, Session, PasswordResetToken, and removes AuthUser. |
Controllers → Bus Wiring services/identity-service/src/main/java/com/tickon/identity/*/infrastructure/web/{AuthController,PasswordResetController,UserController}.java |
Controllers no longer call use-case interfaces directly; they dispatch commands/queries via CommandBus/QueryBus and map CommandResult/QueryResult. Adds GET /v1/users/me that reads X-User-Id. |
Password Reset & Email services/identity-service/src/main/java/com/tickon/identity/auth/application/command/requestpasswordreset/*, .../resetpassword/*, .../query/verifyresettoken/*, services/identity-service/src/main/java/com/tickon/identity/auth/infrastructure/email/{SendGridEmailSender.java,EmailSendException.java} |
New commands/handlers and query for password-reset lifecycle; SendGrid email sender updated to accept String to, uses Personalization, masks email in logs, and throws EmailSendException on failure. |
API Gateway & Security services/api-gateway/src/main/java/com/tickon/gateway/filters/UserIdRelayFilter.java, services/api-gateway/.../SecurityConfig.java, services/api-gateway/.../UserIdRelayFilterTest.java |
Adds global filter to extract JWT subject and set/strip X-User-Id header; expands permitted endpoints for password-reset routes; includes unit tests for header behavior. |
Persistence & Adapters services/identity-service/src/main/java/.../infrastructure/persistence/*RepositoryAdapter.java, .../persistence/mappers/*PersistenceMapper.java |
Repository adapters and mappers updated to accept/return UUID/String instead of value objects; method signatures adjusted (invalidateAllForUser, revokeAllByUserId). |
Security / Hashing / JWT services/identity-service/src/main/java/.../security/{Argon2PasswordHasher,JwtTokenProvider}.java |
Argon2PasswordHasher now hashes to String and verifies against String; JwtTokenProvider generates tokens using UUID userId and signature call-sites updated. |
Metrics & Logging / Observability infra services/identity-service/src/main/resources/logback-spring.xml, services/event-service/*, infra/tempo/*, infra/loki/loki.yaml, docs/plans/2026-02-25-observability-refactor.md |
Removes some MDC fields from JSON logs, adds event-service tracing/logback, adds Tempo metrics_generator config, adds Loki WAL/compactor paths and related docker-compose/env changes, and documents a phased observability refactor. |
Build / Compose / Env .env.local.example, Dockerfile, docker-compose.yml |
Adds PASSWORD_RESET_TOKEN_PEPPER, SENDGRID_API_KEY, SENDGRID_FROM_EMAIL env vars; Dockerfile copies common/src into build; docker-compose adds envs to identity-service and adjusts loki mounts and prometheus flags. |
Tests services/identity-service/src/test/java/... |
Wide test updates: many service tests rewritten as handler tests, fixtures changed to use UUID/UserAuthDataDTO, new tests for Observable buses, metrics, controller current-user endpoint, and UserIdRelayFilter. Numerous test package/import adjustments. |

Two behaviorally distinct scenarios aren't exercised:

A test asserting the expected behavior (skip or set) makes the contract explicit.Pre-existing MDC context: When the filter runs in a thread-pool-reused thread that already has MDC keys set by upstream infrastructure (e.g., a
traceId), doesdoFilterInternalinadvertently wipe those keys on cleanup? Relevant if the implementation callsMDC.clear()unconditionally instead of removing only the keys it set.🤖 Prompt for AI Agents

54-54: PreferSystem.nanoTime()for elapsed-time measurement.
System.currentTimeMillis()is a wall-clock and can jump backwards on NTP corrections, yielding negative or incorrect durations.System.nanoTime()is monotonic and designed for this use-case (convert to ms viaTimeUnit.NANOSECONDS.toMillis()).♻️ Proposed fix

getUser returns Optional<UserResponse> — inconsistent 404 handling vs getCurrentUser.
When the user is not found, getCurrentUser (line 49-50) returns a proper 404 Not Found via ResponseEntity. Here, returning Optional.empty() results in a 200 OK with a null body, which is inconsistent and not RESTful.

Add authorization check to prevent users from deleting accounts other than their own.
The gateway enforces authentication for DELETE requests, but deleteUser() lacks authorization validation. It accepts any authenticated user and deletes the specified user ID without verifying ownership. The X-User-Id header is available (passed by the gateway's UserIdRelayFilter from the JWT subject) but is never extracted or validated in this endpoint.
Either restrict deletion to the authenticated user's own account, or require an admin role:
`@DeleteMapping`("/{id}")

Query design pattern Query<Optional<T>> encodes absence ambiguously—refactor to return non-optional results.
Line 83 uses Query<Optional<UserAuthDataDTO>>, forcing a chain where the query result unwraps to Optional<UserAuthDataDTO>, then the consumer must check isEmpty() at lines 85-90. This conflates two distinct concerns:
- QueryResult semantics (query execution success/failure)
- Resource existence (via Optional presence/absence)
The codebase applies this pattern inconsistently: GetUserAuthDataQuery, GetUserByEmailQuery, and GetUserByUsernameOrEmailQuery all return Query<Optional<UserAuthDataDTO>>, while other queries like VerifyResetTokenQuery return Query<VerifyResetTokenResult> directly.
Solution: Refactor queries to return the resource directly (or throw/return an explicit "not found" result), and let the bus handle the execution envelope via QueryResult alone. This eliminates the unnecessary Optional unwrapping and aligns query semantics.
♻️ Proposed cleaner shape
- Optional<UserAuthDataDTO> userOpt = queryBus.execute(new GetUserAuthDataQuery(session.userId())).orElseThrow();
-
- if (userOpt.isEmpty()) {
- log.warn("Token refresh failed: user not found for sessionId={}", session.id().value());
- metrics.tokenRefresh("failure").increment();
- metrics.tokenRefreshFailure("invalid").increment();

Preserve email validation at the port boundary.
Moving from an Email value object to a raw String removes type-level validation; ensure callers validate/normalize before invoking this port (or keep a value object here). As per coding guidelines, "Check that ports (interfaces) are properly defined".

Replacing UserId VO with raw UUID weakens the domain model.
SessionId is correctly retained as a value object, but userId is now a primitive UUID. This inconsistency creates a type-safety gap: the compiler can no longer distinguish a user's UUID from, say, a session's underlying UUID. Any UUID is now a valid argument at the call site, silently bypassing the domain's semantic boundary.
If the intent is to fully remove VO wrappers from event payloads (e.g., for serialization simplicity), both sessionId and userId should be unwrapped to UUID consistently. Otherwise, UserId should be restored.
♻️ Option A — restore VO consistency (preferred for DDD)
-import java.util.UUID;
+import com.tickon.identity.auth.domain.valueobjects.UserId;
-public record SessionCreatedEvent(SessionId sessionId, UUID userId, Instant occurredOn) implements DomainEvent {
+public record SessionCreatedEvent(SessionId sessionId, UserId userId, Instant occurredOn) implements DomainEvent {
- public SessionCreatedEvent(SessionId sessionId, UUID userId) {
+ public SessionCreatedEvent(SessionId sessionId, UserId userId) {
this(sessionId, userId, Instant.now());
}
}♻️ Option B — full primitive unwrapping (if VOs are intentionally dropped from events)
-public record SessionCreatedEvent(SessionId sessionId, UUID userId, Instant occurredOn) implements DomainEvent {
+public record SessionCreatedEvent(UUID sessionId, UUID userId, Instant occurredOn) implements DomainEvent {
- public SessionCreatedEvent(SessionId sessionId, UUID userId) {
+ public SessionCreatedEvent(UUID sessionId, UUID userId) {
this(sessionId, userId, Instant.now());
}
}As per coding guidelines: "Check for rich domain models (behavior, not just data)" and "Ensure value objects are immutable" — demoting UserId to UUID inside a domain event is primitive obsession and erodes the domain model's expressiveness.

Guard recipient-name derivation against null/invalid email.
event.email() is assumed valid; if it’s null/blank or missing "@", .split("@")[0] can throw or produce an empty name, leading to a failed send. A small pre-check avoids this and keeps error handling intentional.

Use UUID userId instead of UserId VO to match the pattern established by ChangePasswordCommand.
ChangePasswordCommand uses UUID userId (primitive), while DeleteUserCommand uses the domain VO UserId. Commands at the application boundary should carry primitives; handlers are responsible for constructing domain value objects. This keeps commands serializable DTOs decoupled from domain internals. Align DeleteUserCommand with the ChangePasswordCommand pattern by changing UserId userId to UUID userId.

permitAll("/**")disables auth entirely.This bypasses all endpoint protection. If the identity service is reachable outside a strictly internal boundary, it’s a direct security exposure. Consider restricting unauthenticated routes to explicit public endpoints (e.g., login/register/reset) and requiring auth for everything else, or enforce network-level isolation/mTLS if the intent is “gateway-only.”

In
`@services/identity-service/src/main/java/com/tickon/identity/auth/infrastructure/email/SendGridEmailSender.java`:
- Around line 34-36: The sendPasswordResetEmail method builds resetUrl by always
appending "?token=" to emailProperties.getResetUrlBase(), which breaks URLs that
already contain query parameters; update sendPasswordResetEmail to detect
whether emailProperties.getResetUrlBase contains a '?' and use '&token=' when it
does (otherwise use '?token='), leaving the token unencoded as it's already
URL-safe; modify code around sendPasswordResetEmail and the usage of
emailProperties.getResetUrlBase to implement this delimiter-aware concatenation.
- Around line 64-73: In SendGridEmailSender, avoid including the raw SendGrid
response body (which can contain PII) in the EmailSendException message and
collapse the error construction to a single line to satisfy Spotless; change the
error path in the method that checks response.getStatusCode() to build the
exception using only the status code and a safe fixed message (e.g., "SendGrid
email failed with status=<code>, response body omitted for privacy") and throw
new EmailSendException(...) on that single line, leaving the IOException catch
to wrap as EmailSendException as-is; reference the response handling block in
SendGridEmailSender and the EmailSendException type when making the change.
In
`@services/identity-service/src/main/java/com/tickon/identity/shared/kernel/exceptions/IdentityExceptionCodes.java`:
- Around line 6-10: The enum constant formatting in IdentityExceptionCodes is
failing Spotless; reformat the enum declaration so each constant is on its own
line and the enum follows project style (e.g., one constant per line, proper
commas and terminating semicolon before any fields/methods) or simply run the
formatter task (mvn spotless:apply) to automatically fix the formatting for
IdentityExceptionCodes and re-run the build; make sure symbols like
VALIDATION_FAILED, INVALID_CREDENTIALS, ACCESS_DENIED, RESOURCE_NOT_FOUND,
INVALID_PASSWORD, INVALID_EMAIL, INVALID_USERNAME, INVALID_ID, SESSION_REVOKED,
SESSION_EXPIRED, and INVALID_REFRESH_TOKEN are preserved exactly.
In
`@services/identity-service/src/main/java/com/tickon/identity/user/domain/exceptions/DuplicateUsernameException.java`:
- Around line 1-4: The Spotless CI violations mean this file
(DuplicateUsernameException) and others need formatting; run mvn spotless:apply
in the repository root, reformat the changed files (including
com.tickon.identity.user.domain.exceptions.DuplicateUsernameException and its
imports/package header), commit the resulting changes, and re-run validation so
Spotless passes before merging.
In
`@services/identity-service/src/main/java/com/tickon/identity/user/domain/exceptions/InvalidUsernameException.java`:
- Around line 3-4: The Spotless formatting check is failing in multiple files
(including InvalidUsernameException.java); run the formatter and commit the
changes: execute mvn spotless:apply at the repository root (or apply your IDE's
Spotless plugin) to fix import/order/formatting issues, verify that files such
as the InvalidUsernameException class now meet Spotless rules, then commit the
reformatted files.
- Around line 10-11: InvalidUsernameException currently calls
super(IdentityExceptionCodes.INVALID_USERNAME, "Invalid username") which loses
the offending value; update the constructor in InvalidUsernameException to
include the username in the exception message (e.g., "Invalid username: " +
username or String.format) so that getMessage() returns the username-aware
message, ensuring you reference the username field and the constructor that sets
this.username and keep the IdentityExceptionCodes.INVALID_USERNAME code
unchanged.
In
`@services/identity-service/src/test/java/com/tickon/identity/shared/infrastructure/SpringCommandBusTest.java`:
- Around line 108-114: The Spotless CI failure is caused by the line break in
the assertion chain inside the test shouldThrowWhenNullCommandDispatched;
reformat the assertion so assertThatThrownBy(() ->
commandBus.execute(null)).isInstanceOf(IllegalArgumentException.class) stays on
the same line (leaving .hasMessageContaining("Command must not be null") on the
following chained line is fine) to satisfy the required single-line chain for
the SpringCommandBus.execute null-check test.
In
`@services/identity-service/src/test/java/com/tickon/identity/shared/platform/web/IdentityMdcFilterTest.java`:
- Line 1: Spotless formatting violations are causing CI failures; run the
formatter and commit the results: execute mvn spotless:apply in the repository
root, review and stage the changes produced for the test class
IdentityMdcFilterTest (and any other files modified), ensure the file compiles
and tests still pass, then commit and push the formatted files so the Spotless
check in CI will pass.
- Around line 73-92: The test should verify the filter actually delegates to the
FilterChain; in shouldPreserveExistingMdcKeysAndRemoveOnlyUserId add a
verification that chain.doFilter(request, response) was invoked after calling
filter.doFilterInternal(request, response, chain). Ensure you keep the existing
MDC assertions in the doAnswer and then call verify(chain).doFilter(request,
response) (using the same mocked chain and request/response) to confirm the
chain was executed.

Outside diff comments:
In
`@services/identity-service/src/main/java/com/tickon/identity/bootstrap/config/SecurityConfig.java`:
- Around line 16-19: The security config currently permits all routes: in
SecurityConfig where you configure http (authorizeHttpRequests and
requestMatchers("/**").permitAll()), restrict unauthenticated access to explicit
public endpoints only (e.g., login/register/reset or any "/auth/**" or
"/public/**" routes) and require authentication for everything else by replacing
the blanket permitAll with a whitelist of permitAll matchers and then chaining a
fallback anyRequest().authenticated() (keep the existing stateless session
policy and other settings).
- Around line 3-20: The file SecurityConfig contains Spotless formatting
violations (imports and method chaining style) causing CI to fail; run the
formatter (mvn spotless:apply) then fix the import ordering and the fluent
chaining in the SecurityConfig.securityFilterChain method so it matches project
style (ensure imports like org.springframework.context.annotation.Bean,
`@Configuration` and the HttpSecurity chain lines are formatted per Spotless
rules), re-run mvn spotless:check and commit the reformatted file.
In
`@services/identity-service/src/main/java/com/tickon/identity/user/application/command/register/RegisterUserCommandHandler.java`:
- Around line 1-72: Spotless CI failed due to formatting issues in
RegisterUserCommandHandler.java; run mvn spotless:apply (or your IDE's formatter
with the project's Spotless settings), reformat the file (ensure imports,
indentation, spacing around methods like handle(RegisterUserCommand) and
getCommandClass(), and any trailing whitespace are fixed), verify no Spotless
violations remain, then commit the updated RegisterUserCommandHandler.java and
re-run the build.
- Around line 43-58: Pre-checks in RegisterUserCommandHandler can miss
race-condition violations because unique partial indices (ux_users_email_active,
ux_users_username_active) may cause DataIntegrityViolationException at save
time; update UserRepositoryAdapter.save() to catch
DataIntegrityViolationException (or underlying constraint violations) and
translate them into the domain exceptions DuplicateEmailException or
DuplicateUsernameException as appropriate so callers (e.g.,
RegisterUserCommandHandler) always receive domain-level errors instead of raw DB
exceptions.
In
`@services/identity-service/src/test/java/com/tickon/identity/auth/infrastructure/web/AuthControllerTest.java`:
- Line 1: The Spotless formatting check is failing for this file (and others);
run the formatter and commit the fixes: execute mvn spotless:apply locally,
review changes (including formatting in AuthControllerTest and related classes
in com.tickon.identity.auth.infrastructure.web), stage and commit the updated
files, then push the branch so CI can re-run with Spotless passing.
- Around line 40-51: Add failure-path unit tests in AuthControllerTest: create
shouldReturn401_WhenLoginCommandFails and
shouldReturn401_WhenRefreshCommandFails that use mockMvc and objectMapper like
the existing happy-path tests but stub commandBus.execute(...) to return new
CommandResult.Failure("...") instead of Success; for the login test build a
LoginRequest and assert mockMvc POST /v1/auth/login returns
status().isUnauthorized(), and for the refresh test build the appropriate
refresh request (same pattern as the successful refresh test) and assert POST
/v1/auth/refresh returns status().isUnauthorized(); reuse the same
mocking/perform pattern (commandBus, mockMvc.perform, json content) used in the
existing tests in AuthControllerTest.
- Around line 54-59: Add the same Mockito verification used in the logout
invalid test to ensure the command bus is never invoked: in the test method
shouldReturnBadRequest_WhenPayloadIsInvalid, after the
mockMvc.perform(...).andExpect(status().isBadRequest()) call add
verify(commandBus, never()).execute(any()) (using the same commandBus, execute
and any() symbols as in shouldReturnBadRequest_WhenLogoutRequestIsInvalid) so
the test asserts the bus is not called if the payload is invalid.
In
`@services/identity-service/src/test/java/com/tickon/identity/shared/platform/metrics/IdentityMetricsTest.java`:
- Line 32: Spotless is failing because long chained calls in IdentityMetricsTest
exceed the formatter's line-length (e.g., the
registry.find(...).tag(...).counter() calls); run mvn spotless:apply to
autoformat, and if needed manually break those long chains across lines (or
extract intermediate variables) so each method call (registry.find(...),
.tag(...), .counter()) sits on its own line; update the occurrences that match
the pattern in IdentityMetricsTest (registry.find(...).tag(...).counter()) to
comply with Spotless formatting and commit the changes.

Duplicate comments:
In
`@services/identity-service/src/main/java/com/tickon/identity/auth/application/command/login/LoginCommandHandler.java`:
- Around line 64-82: In LoginCommandHandler replace INFO/WARN logs that print
cmd.usernameOrEmail() with non-PII-safe logging: either log at DEBUG level using
log.debug(...) or redact the identifier (e.g., show only a hashed or masked
version) before logging; update the log.info(...) and both log.warn(...) calls
around user lookup and invalid password to avoid printing cmd.usernameOrEmail(),
keeping the existing messages and metrics.increment() calls intact while
ensuring only redacted or debug-level output contains the raw username/email.
In
`@services/identity-service/src/main/java/com/tickon/identity/shared/kernel/exceptions/IdentityExceptionCodes.java`:
- Line 3: IdentityExceptionCodes is coupling the kernel to Spring by importing
org.springframework.http.HttpStatus; remove that import and any HttpStatus-typed
fields/constructors in the IdentityExceptionCodes enum and replace them with a
transport-agnostic representation (e.g., an int statusCode or a custom
KernelErrorCode field) while keeping existing enum names and message keys
intact; update the enum constructor and getter signatures (e.g.,
getStatusCode()) so the web layer can map these codes to
org.springframework.http.HttpStatus inside IdentityGlobalExceptionHandler
(implement mapping there), ensuring the kernel no longer references Spring
types.

Nitpick comments:
In
`@services/identity-service/src/main/java/com/tickon/identity/user/domain/exceptions/DuplicateEmailException.java`:
- Around line 7-12: In DuplicateEmailException, validate the constructor
parameter before assigning to the field: in the DuplicateEmailException(String
email) constructor check that email is not null and not blank (e.g., throw
IllegalArgumentException with a clear message if invalid) before calling super
or assigning this.email; ensure the invariant that the private final String
email is always a non-empty value when stored and preserve the existing use of
IdentityExceptionCodes.DUPLICATE_EMAIL and the "Email already in use" message.
In
`@services/identity-service/src/main/java/com/tickon/identity/user/domain/exceptions/DuplicateUsernameException.java`:
- Around line 7-12: The DuplicateUsernameException constructor stores the
incoming username without validation; ensure the constructor for
DuplicateUsernameException validates its parameter (e.g., use
Objects.requireNonNull(username, "username must not be null") and additionally
reject empty/blank strings by throwing IllegalArgumentException with a clear
message) before assigning to the private final String username field so
null/blank values cannot propagate to handlers.
In
`@services/identity-service/src/test/java/com/tickon/identity/auth/infrastructure/web/AuthControllerTest.java`:
- Line 44: The test uses a raw any() matcher for commandBus.execute which hides
command-type regressions; replace any() with typed Mockito matchers (e.g.,
Mockito.isA(YourExpectedCommandClass.class) or argThat(cmd -> cmd instanceof
YourExpectedCommandClass && /* optional additional checks */)) for each stub
that returns new CommandResult.Success<>(response) so the stubs only match the
intended concrete command types; update all occurrences that currently use any()
on commandBus.execute to use the specific command classes used by the test
assertions.
In
`@services/identity-service/src/test/java/com/tickon/identity/shared/platform/metrics/IdentityMetricsTest.java`:
- Around line 22-27: Add unit tests for the tagged metric methods to cover
null/blank tag values and accumulation: for each metrics method
registrationFailed, loginAttempt, loginFailure, sessionRevoked, tokenRefresh,
tokenRefreshFailure, passwordResetFailed, emailSent add two tests — one that
calls the method twice with the same tag value and asserts
registry.find("identity.<metric_name>") .tag(...).counter().count() == 2.0 to
catch re-registration bugs, and one that verifies behavior when a tag value is
null or blank (either assert no exception is thrown or assert the expected
exception/contract), referencing the exact metric factory methods (e.g.,
metrics.registrationFailed("reason"), metrics.emailSent("outcome", type)) so
tests locate the code under test.

Handle existing query delimiters when constructing reset URL.
The token uses URL-safe Base64 (alphabet: A-Za-z0-9-_), so additional encoding is unnecessary. However, the delimiter handling is valid: if resetUrlBase already contains query parameters, appending ?token= will break the URL. Use & when needed.
🔧 Suggested improvement (delimiter-aware)
- String resetUrl = emailProperties.getResetUrlBase() + "?token=" + resetToken;
+ String resetUrlBase = emailProperties.getResetUrlBase();
+ String delimiter = resetUrlBase.contains("?") ? "&" : "?";

🌐 Web query:
SendGrid /mail/send API error response body PII recipient email information
💡 Result:
SendGrid’s POST /v3/mail/send error responses generally use a JSON body like:
{
"errors": [
{ "message": "...", "field": "...", "help": "...", "id": "..." }
]
}The field value is typically just a JSON path (e.g., personalizations.0.to) rather than an email address. [1]
However, some validation errors are documented as including the offending recipient email in the human-readable message. For example, for duplicate recipients, the documented error message format is:
“Each unique email address … should only be included once. You have included [email address] more than once.” [2]
That implies the actual API response may contain the duplicated recipient email address substituted into the message (i.e., potential PII exposure in error bodies). [2]
Practical takeaway: treat /mail/send error response bodies as potentially containing recipient email PII and redact/avoid logging the raw errors[].message (and any other raw response body) in production logs. [1][2]

Sanitize SendGrid response bodies to prevent PII exposure and consolidate formatting to comply with Spotless.
SendGrid error responses can include recipient email addresses in duplicate recipient error messages, presenting a PII risk when logged upstream. Additionally, the String.format(...) call exceeds the 120-character line split enforced by Spotless (set in java-formatter.xml).
Sanitize or omit the response body and consolidate to a single line:
Suggested fix
- String errorMessage = String.format("SendGrid email failed with status=%s, body=%s",
- response.getStatusCode(), response.getBody());
+ String responseBody = response.getBody();
+ String safeBody = responseBody == null ? "" : responseBody.replaceAll("[\\r\\n]", " ");
+ if (safeBody.length() > 200) {
+ safeBody = safeBody.substring(0, 200) + "...";
+ }
+ String errorMessage = String.format("SendGrid email failed with status=%s, body=%s", response.getStatusCode(), safeBody);
throw new EmailSendException(errorMessage);🧰 Tools

Missing verify(chain).doFilter(request, response) — chain invocation unconfirmed.
Every other test in this file verifies that chain.doFilter was actually called. shouldPreserveExistingMdcKeysAndRemoveOnlyUserId skips this, meaning the test would pass even if the filter short-circuits and never delegates to the chain.

Defer domain event publishing until transaction commit.
publishAll() executes synchronously without transactional safety. Events are published via Spring's ApplicationEventPublisher.publishEvent() immediately within the @Transactional method. If the transaction rolls back after line 82, subscribers have already processed events for uncommitted data.
Use @TransactionalEventListener(phase = TransactionPhase.AFTER_COMMIT) on subscribers, or implement an outbox pattern to defer publishing until commit succeeds.
Applies to lines 82–83 and similar event publishing within this handler.

Create UserNotFoundException domain exception and use it consistently across command handlers
Line 42 uses a generic runtime exception for a domain business case. The codebase has an established pattern: domain exceptions extend IdentityDomainException and are caught by IdentityGlobalExceptionHandler. IllegalStateException bypasses this mapping and results in an unmapped 500 error. Other command handlers (e.g., LoginCommandHandler) correctly throw domain exceptions like InvalidCredentialsException.
Create a UserNotFoundException following the existing pattern in services/identity-service/src/main/java/com/tickon/identity/user/domain/exceptions/, then update both ChangePasswordCommandHandler (line 42) and DeleteUserCommandHandler (line 27) to use it.

if it is null/blank, log a warning, increment the metrics (e.g.,
metrics.tokenRefreshFailure("blank" or "missing")) and throw/return the same

semantics; only call refreshTokenHasher.hash and
sessionRepository.findByRefreshTokenHash when the token string is non-empty.

- Line 22: The Spotless formatting check failed for the ObservableCommandBus
class due to the field declaration "private final CommandBus delegate;" — run
the formatter (mvn spotless:apply) or reformat the field declaration to match
project style (e.g., spacing, indentation, and ordering) so the declaration for
delegate in class ObservableCommandBus complies with Spotless rules before
committing.
- Around line 73-75: rootCause(Throwable) currently unwraps only one level and
can miss deeply nested causes; update ObservableCommandBus.rootCause to
iteratively traverse ex.getCause() until there is no further cause (guarding
against cycles by stopping if cause equals current) and return the deepest
non-null cause so downstream checks (e.g., domain exception detection) operate
on the actual root cause.

registry and assigns this.delegate/this.registry) violates Spotless formatting;
run mvn spotless:apply to reformat the constructor signature and surrounding
whitespace so it matches the project's style rules (ensuring the parameter list
and indentation conform to Spotless expectations) and then recompile to confirm
the formatting issue is resolved.
- Around line 32-51: ObservableQueryBus.execute currently dereferences query
without a null guard, causing an NPE; add the same null-check behavior as
ObservableCommandBus.execute: at the start of ObservableQueryBus.execute
validate that query != null and throw new IllegalArgumentException("query must

getQueryName() is never called on a null reference; update unit tests if present

RegistrationMetricsPort instead of IdentityMetrics (constructor and any
field/usages), and implement RegistrationMetricsPort in the existing
IdentityMetrics adapter in the infrastructure layer so the handler stays
infrastructure-agnostic.
- Around line 41-42: The register handler publishes events inside the
`@Transactional` RegisterUserCommandHandler.handle method via
ApplicationEventPublisher.publishAll(), which can notify external consumers

either (A) switching to publish domain events as Spring events after commit
using `@TransactionalEventListener`(phase = TransactionPhase.AFTER_COMMIT) and
emitting lightweight event objects from handle (or via an in-memory accumulator)
or (B) persist events to an outbox table within the same transaction (from
handle), then have an asynchronous dispatcher read the outbox and call
ApplicationEventPublisher.publishAll() after commit; apply the same change to
other handlers that call publishAll() (e.g., LoginCommandHandler,
LogoutCommandHandler, ResetPasswordCommandHandler).
- Around line 43-50: The pre-checks using existsByEmail and existsByUsername can
race; update UserRepositoryAdapter.save() so that the call to
jpaRepository.save(...) is wrapped to catch DataIntegrityViolationException (and
root SQL constraint causes) and translate them into the domain exceptions
DuplicateEmailException or DuplicateUsernameException as appropriate (and call

the existing IdentityMetrics implementation via your DI configuration.
- Around line 53-54: The handler RequestPasswordResetCommandHandler::handle is
annotated `@Transactional` but calls DomainEventPublisher.publishAll() inside the
transaction (the publishAll() call), causing events to be emitted before commit;
move event publication out of the transactional body so events are only
published after successful commit. Fix by having handle collect/return the
domain events (or let DomainEventPublisher buffer them) and invoke publication
from a transaction-aware hook (e.g. a `@TransactionalEventListener`(phase =
TransactionPhase.AFTER_COMMIT) or an after-commit callback) or delegate to a
publisher implementation that defers sending until transaction commit; update
codepaths referencing publishAll() in handle to instead hand off events to that
after-commit mechanism.

- Around line 25-32: Add an explicit read-only transaction boundary to the query
handler by annotating the handler with Spring's transactional read-only
semantics: apply `@Transactional`(readOnly = true) to the handle method (or the
GetUserAuthDataQueryHandler class) so that the repository read via
userRepository.findById(...) runs inside a read-only transaction; import
org.springframework.transaction.annotation.Transactional if missing and ensure
the annotation is placed on the handle(...) method that maps toDTO to create
consistent query semantics.
In
`@services/identity-service/src/test/java/com/tickon/identity/auth/application/command/login/LoginCommandHandlerMetricsTest.java`:
- Around line 56-57: The test method names in LoginCommandHandlerMetricsTest
(e.g., successfulLoginIncrementsSuccessCounterAndSessionCreated and the other
two tests around lines 73-74 and 87-88) do not follow the repository's
should_X_When_Y naming convention; rename each test to the
should_{ExpectedOutcome}_When_{Condition} pattern (for example
should_IncrementSuccessCounterAndCreateSession_When_LoginSucceeds) so they match
other tests and keep the class name LoginCommandHandlerMetricsTest unchanged.
In
`@services/identity-service/src/test/java/com/tickon/identity/shared/platform/bus/ObservableQueryBusTest.java`:
- Around line 17-81: Add a unit test to ObservableQueryBusTest that verifies a
null query is rejected: when ObservableQueryBus implements the same null-guard
as ObservableCommandBus, add a test method (e.g.,
should_ThrowIllegalArgumentException_When_QueryIsNull) that calls
bus.execute(null) and asserts an IllegalArgumentException is thrown; reference
the test class ObservableQueryBusTest and the bus.execute(...) invocation so the
new test aligns with the other tests in this file.
In
`@services/identity-service/src/test/java/com/tickon/identity/shared/platform/metrics/IdentityMetricsTest.java`:
- Around line 29-35: Add tests in IdentityMetricsTest to cover edge-case
reason/type parameters: create tests that call metrics.registrationFailed("")
and metrics.loginFailure("") and assert that
registry.find("identity.user.registration.failed").tag("reason","").counter()
and registry.find("identity.user.login.failed").tag("reason","").counter() exist
and have count 1.0; also add tests that call
metrics.registrationFailed("weird/!?%#") and metrics.loginFailure("weird/!?%#")
and assert the registry.find(...).tag("reason","weird/!?%#").counter() (or tag
"type" if applicable) exists and has count 1.0 to validate special-character
handling. Ensure you reference the same metrics instance used elsewhere in the
test class and reuse registry.find(...) calls to locate counters.
- Around line 21-27: The test shows mixed API patterns:
metrics.userRegistered().increment() vs metrics.registrationFailed("reason")
(which increments internally); make them consistent by choosing one pattern and
applying it across IdentityMetrics and tests—either (A) convert
Counter-returning methods like userRegistered() to void methods that perform the
increment internally, or (B) convert tagged/void methods like
registrationFailed(String) to return a Counter so callers invoke .increment();
update the IdentityMetrics method implementations and all callers/tests
(including IdentityMetricsTest assertions that read
registry.find("identity.user.registered").counter()) to match the chosen
convention.

Add null/blank validation for refresh token input.
If command.refreshToken() is null or blank, refreshTokenHasher.hash() may throw an unexpected exception or produce invalid behavior. Validate early for clearer error semantics.

Shallow root cause resolution may miss deeply wrapped exceptions.

Missing null-query guard (inconsistent with ObservableCommandBus).
ObservableCommandBus.execute() throws IllegalArgumentException when command is null (see ObservableCommandBus.java lines 33-35). This bus lacks the same guard, which will cause an NPE at query.getQueryName().
Proposed fix
