+# Stirling-PDF: Spring Boot → Quarkus Migration — Continuation Handoff
+
+> **Purpose:** everything needed to resume this migration in a fresh session. Read this top-to-bottom
+> before touching anything. Companion doc `migration-report.md` has the higher-level summary; this
+> file is the working/continuation guide with the concrete state, commands, fixed bugs, remaining
+> bugs, and the recurring patterns you need to apply.
+
+---
+
+## 0. TL;DR status
+
+- **2026-06-19 — merged `main` (136 commits) into `migration/run-02`.** Resolved 69 conflicts and
+  did **full Spring removal + Quarkus migration of every newly pulled-in file** (36 Spring-bearing
+  files: 21 proprietary + 15 saas). Net effect on main: legacy credits engine deleted (#6687,
+  replaced by PAYG #6589); the proprietary **policy** subsystem and the new **PAYG** subsystem
+  migrated to CDI/JAX-RS/Panache. Verified: 0 conflict markers, 0 `org.springframework` imports in
+  any main source. **`core` + `proprietary` compile; `proprietary` Quarkus-augments + boots + serves
+  real traffic; `saas` now compiles AND augments too** (previously ~28 CDI issues). Cross-file fix:
+  `PolicyExecutor`/`DownstreamEntitlementError` now carry HTTP status+body via
+  `jakarta.ws.rs.WebApplicationException` (was Spring `RestClientResponseException`);
+  `AiWorkflowService.paygLimitResponseOrNull` rewired to it. Repo `save()` shim added to the Panache
+  repos whose callers/tests expect Spring-Data `save()`.
+- **Branch:** `migration/run-01` (all work committed locally, **nothing pushed** — `origin` is the
+  public `Stirling-Tools/Stirling-PDF` repo; do not push without the owner's say-so).
+- **Default flavor (`proprietary`):** compiles, Quarkus-augments, boots, and serves real traffic in
+  Docker. ✅
+- **Cucumber API e2e (full-tool Docker image):** baselines, newest first:
+  - **Run 2 (login off, this session's fixes, no JWT mechanism): 223 / 258 pass**, 35 failed, 80
+    skipped. Up from the prior **183 / 258** baseline (+40). Eliminated buckets: split
+    `PDF corrupted` 8→0, `FileAlreadyExists` 8→0, `Admin login failed (500)` 17→0.
+  - **Run 3 (login off + `V2=true` + the new JWT Bearer mechanism): the 80 JWT/admin scenarios now
+    RUN (0 skipped)** because the `login → /me` probe passes. See §6.E / "Session 2". Final tally
+    recorded in §9.
+- **Stack:** Quarkus 3.33.2 LTS, **Java 25** (mandatory — see §2), Hibernate ORM Panache,
+  quarkus-rest (RESTEasy Reactive), quarkus-oidc, quarkus-undertow (servlet, for filters), OpenSAML 5.
+- **`saas` flavor:** compiles but full augmentation has ~28 CDI issues (design-level follow-up).
+- **JWT Bearer login:** ✅ works end-to-end (token issue + validate → `SecurityIdentity`, role
+  mapping, `@RolesAllowed`). **OAuth2/OIDC + SAML2 SSO:** ✅ both work end-to-end against the
+  `testing/compose` Keycloak stacks; `validate-oauth-test.sh` and `validate-saml-test.sh` both pass
+  (see §6.F). The default e2e Docker image + build helper are committed at `docker/quarkus/` (§3.3).
+
+---
+
+## 1. Repo / flavor layout
+
+Multi-module Gradle build, three selectable flavors via `STIRLING_FLAVOR` (or `ENABLE_SAAS` /
+`DISABLE_ADDITIONAL_FEATURES`):
+
+| Flavor | Modules included | Notes |
+|--------|------------------|-------|
+| `core` | `:common`, `:stirling-pdf` (core) | OSS only |
+| `proprietary` (**default**) | + `:proprietary` | what all the e2e work targets |
+| `saas` | + `:saas` | opt-in: `STIRLING_FLAVOR=saas`; not yet augmentable |
+
+Module → directory:
+- `:stirling-pdf` → `app/core` (the runnable Quarkus app; applies the `io.quarkus` gradle plugin)
+- `:common` → `app/common` (library; CDI beans / JAX-RS / entities)
+- `:proprietary` → `app/proprietary` (library)
+- `:saas` → `app/saas` (library, only on saas flavor)
+
+Quarkus only discovers beans/entities in dependency jars that carry a **Jandex index**; the library
+modules are indexed via `quarkus.index-dependency.*` in
+`app/core/src/main/resources/application.properties`.
+
+---
+
+## 2. Java 25 is mandatory (don't regress this)
+
+- The build uses a **JDK 25 toolchain** (`build.gradle` `subprojects { java { toolchain = 25 } }`).
+- The app is compiled to **class-file version 69 (Java 25)** — it will NOT run on JDK 21.
+- **The host's default `java` on the PATH is JDK 21.** Use the toolchain JDK 25 explicitly:
+  - `JAVA_HOME` points to a Temurin 25 JDK (`C:\Users\systo\scoop\apps\temurin25-jdk\current`).
+  - In Git Bash run the jar with `"$JAVA_HOME/bin/java" -jar ...` (host `java` = 21 → `UnsupportedClassVersionError`).
+- The Docker base image `stirlingtools/stirling-pdf-base:1.0.2` ships **Temurin 25.0.2** — so the
+  container runtime is JDK 25 already. Keep it that way; do not switch the base image to a JRE < 25.
+- Gradle build images / CI also pin `gradle:9.3.1-jdk25` and `eclipse-temurin:25-jre-noble`.
+
+---
+
+## 3. Build → package → run → test (the exact loop)
+
+### 3.1 Build the runnable jar
+```bash
+./gradlew :stirling-pdf:quarkusBuild -x test --console=plain
+```
+- Produces the **runnable uber-jar** at: `app/core/build/stirling-pdf-2.12.0-runner.jar`
+  - `Main-Class: stirling.software.SPDF.SPDFApplication`.
+- ⚠️ **GOTCHA:** `app/core/build/libs/stirling-pdf-2.12.0.jar` is the *plain* (non-runnable) jar with
+  an empty manifest. The upstream `docker/embedded/Dockerfile` copies `libs/*.jar` — that's now the
+  WRONG jar. Always use the `-runner.jar`. (`quarkus.package.jar.type=uber-jar` is set in
+  application.properties.)
+- ⚠️ If the build fails with `Unable to delete .../-runner.jar`, a previous `java -jar` is still
+  holding it. Kill it: PowerShell `Get-CimInstance Win32_Process -Filter "Name='java.exe'" | ?{ $_.CommandLine -like '*stirling-pdf-2.12.0-runner*' } | %{ Stop-Process -Id $_.ProcessId -Force }`.
+
+### 3.2 Run standalone for a quick boot check (host JDK 25, fastest)
+```bash
+SECURITY_ENABLELOGIN=false QUARKUS_HTTP_PORT=8095 \
+QUARKUS_DATASOURCE_JDBC_URL="jdbc:h2:mem:t;DB_CLOSE_DELAY=-1;MODE=PostgreSQL" \
+nohup "$JAVA_HOME/bin/java" -jar app/core/build/stirling-pdf-2.12.0-runner.jar > /tmp/boot.log 2>&1 &
+# success line in log: "Stirling-PDF running on port: 8095"  (this app does NOT print Quarkus' "Listening on")
+```
+Health: `curl localhost:8095/api/v1/info/status` → `{"version":"2.12.0","status":"UP"}`.
+
+### 3.3 The "normal" Docker image (full tools) — what the cucumber e2e uses
+The upstream `docker/embedded/Dockerfile` is **Spring-Boot-specific** (uses
+`java -Djarmode=tools -jar app.jar extract --layers` + `spring-boot-loader` layers) and does NOT
+work with the Quarkus jar. For e2e I built an ad-hoc image layering the runner-jar on the prebuilt
+**base image** (which already has Java 25 + LibreOffice + Tesseract + qpdf + Ghostscript + Calibre +
+Python). **This Dockerfile lives in a temp dir and needs to be committed into the repo** (see §6 TODO).
+
+Build context (currently ephemeral at the bash path `/tmp/sp-full` =
+`C:\Users\systo\AppData\Local\Temp\sp-full`): `app.jar` (the runner jar), `fonts/*.ttf`, and this
+Dockerfile:

+
+### 3.4 Run the cucumber (behave) suite
+- Tests live in `testing/cucumber/` — Python **behave** (BDD), pure HTTP via `requests` (no browser).
+- **Target URL is hardcoded `http://localhost:8080`** in `features/steps/step_definitions.py`
+  (lines ~584/592/601) and `features/environment.py`. Easiest is to run the app on 8080.
+- `behave.ini` excludes `features/(enterprise|payg)` and tag `~@manual` by default.
+- `environment.py` probes `/api/v1/auth/login` (admin/stirling) at startup; if JWT/login is not
+  functional (login disabled / V2) it **skips** all `@jwt @login @me @refresh @token @mfa @apikey
+  @admin_settings @audit @signature @team @user_mgmt` scenarios → ~80 skips. That's expected.
+
+Install deps + run:
+```bash
+cd testing/cucumber
+pip install -r requirements.txt        # behave, requests, pypdf, reportlab, psycopg, pillow, ...
+TEST_CONTAINER_NAME=sp-e2e TEST_REPORT_DIR=/tmp python -m behave --no-capture --format progress2
+# single feature:  python -m behave features/general.feature
+# one scenario:    python -m behave features/general.feature:22 --format plain
+```
+The official CI driver is `testing/test.sh` (builds images via `docker/embedded/Dockerfile.*` and
+runs behave) — it will need the Dockerfile fixes from §6 before it works on Quarkus.
+

+
+## 4. Bugs FIXED this session (with the *why*, so you can spot siblings)
+
+### Session 2 (branch `claude/happy-chaplygin-906fe7`, fast-forwarded from `migration/run-01`)
+
+Newest first. These took the login-off suite **183 → 223** and then wired JWT so the **80 skipped
+JWT/admin scenarios run** (run 3, §9):
+
+1. **JWT Bearer → `SecurityIdentity` was never populated** → every user-scoped endpoint that reads
+   `SecurityIdentity.getPrincipal()` (folders, files, `/me`, user/team settings…) failed, and the
+   `environment.py` probe (`login → /me`) failed so ~80 scenarios auto-skipped. Added a custom
+   `HttpAuthenticationMechanism` + `IdentityProvider` in
+   `app/proprietary/.../security/identity/` (`JwtBearerAuthenticationMechanism`,
+   `JwtTokenIdentityProvider`): extract `Authorization: Bearer`, validate via the existing
+   `JwtService` (jjwt + keystore), build a `QuarkusSecurityIdentity` and map the `role` claim
+   (`ROLE_ADMIN` → also add `ADMIN` so `@RolesAllowed("ADMIN")` matches). Returns no identity when
+   no Bearer is present, so the X-API-KEY / login-off open-endpoint path is unaffected. **This is the
+   IdentityProvider that ~10 `// TODO: Migration required` comments across the security/storage code
+   asked for.** Run with `V2=true`.
+2. **No admin user was ever created** → all logins failed "No user found: admin". `InitialSecuritySetup`
+   was a Spring `@Component` (eagerly constructed, `@PostConstruct` ran every boot); the migration
+   made it a lazy `@ApplicationScoped` whose `@PostConstruct` never ran. Restored eager init via
+   `@Observes StartupEvent`. **Pattern: any migrated `@PostConstruct`-on-`@ApplicationScoped` startup
+   bean with no injector is dead code — grep for them.**
+3. **Eager init then exposed two latent bugs** (both real, both now fixed):
+   - `@Produces @ApplicationScoped DataSource` → Arc generated the client proxy in the JDK-sealed
+     `javax.sql` package → `NoClassDefFoundError` on first use. Fix: `@Singleton` (pseudo-scope, no
+     proxy). **Audit other `@Produces @ApplicationScoped` whose return type is a `java.*`/`javax.*`
+     type.**
+   - Panache `persist()` in the `StartupEvent` observer ran with no transaction (Spring Data wrapped
+     `save()` implicitly). Fix: `@Transactional` on the observer.
+4. **Login returned 500 instead of 401** for unknown user / bad password. `CustomUserDetailsService`
+   threw `IllegalArgumentException`, but `AuthController` catches the migration shim
+   `stirling.software.common.security.UsernameNotFoundException`. Made the service throw the shim
+   type. **Sibling: the locked-account path still throws `IllegalStateException` — wire it similarly
+   when needed.**
+5. **`@Transactional` missing on policy-store reads** (`JpaPolicyStore.all()`,
+   `findByTriggerType()`) → the scheduled folder-watch/schedule triggers threw
+   `ContextNotActiveException` off-request (§6.C). The reads are reached via the CDI proxy so a
+   method-level `@Transactional` applies even from the background virtual-thread executor.
+6. **Split scenarios sent a duplicate `fileInput` text part** (`| fileInput | fileInput |` in
+   `general.feature`) alongside the file part; Quarkus `@RestForm FileUpload` bound the *text* part
+   ("fileInput", 9 bytes) → "PDF corrupted". Spring ignored the stray part. Removed the redundant
+   rows (the file is already attached via the generate step). **Real clients send one part, so this
+   is a test artifact, not a server tolerance gap worth chasing.**
+7. **e2e Docker build is now first-class:** `docker/quarkus/Dockerfile` (+ `README.md`,
+   `build-and-run.sh`) layers the runner-jar on the base image, and `.dockerignore` re-includes
+   `app/core/build/*-runner.jar` (it was excluded by `**/build/`, so a clean `docker build` had been
+   silently relying on BuildKit cache).
+
+### Session 1
+
+1. **`MultipartFile.transferTo` didn't overwrite** (`a30d524ec`).
+   `app/common/.../model/MultipartFile.java` + `.../model/multipart/FileUploadMultipartFile.java`
+   used `Files.copy(in, dest)` without `REPLACE_EXISTING`. Callers do
+   `Files.createTempFile(...)` (creates the file) then `transferTo(thatPath)` → `FileAlreadyExistsException`.
+   Spring's `transferTo` overwrites. **Fixed** by adding `StandardCopyOption.REPLACE_EXISTING`.
+   Fixes the whole class of `/api/v1/misc/*` failures (scanner-effect, replace-invert, ocr,
+   update-metadata, unlock-pdf-forms, repair, extract-image-scans, add-page-numbers, …).
+
+2. **`maxDPI` defaulted to 0** (`a30d524ec`).
+   `ApplicationProperties.System.maxDPI` is a primitive `int` (→ 0 when not bound from settings).
+   Every DPI guard (`dpi > maxDPI`) then failed with *"maximum safe limit of 0"*. The
+   `settings.yml.template` default is 500. **Fixed** by `private int maxDPI = 500;`.
+   ⚠️ Root cause hint: this strongly suggests **settings.yml → ApplicationProperties config binding
+   is incomplete in the Quarkus migration**. Other primitive/unset fields may also be silently
+   wrong. Worth a dedicated audit (see §5).
+
+3. **Request-path `HttpServletRequest` → `UT000048` "No request is currently active"** (`860bd6e63`,
+   `4b572852c`). This was the dominant blocker. `quarkus-rest` (RESTEasy Reactive) runs handlers on
+   reactive/worker threads where the undertow servlet request context is NOT active, so ANY
+   `HttpServletRequest.getX()` throws. Fixed in:
+   - `GlobalExceptionHandler` (an `ExceptionMapper` that threw while handling *every* error, masking
+     the real cause) → `@Context UriInfo` + exception-safe `requestUri()`.
+   - `ControllerAuditAspect`, `AuditAspect` → route through the already-guarded
+     `AuditService.getCurrentRequest()` (returns null off-request) + a guarded `safeResponse()`.
+   - `AutoJobAspect`, `JobExecutorService` → inject `io.quarkus.vertx.http.runtime.CurrentVertxRequest`,
+     read query-param/method/path/attributes from the Vert.x request, degrade to null/no-op.
+   - `AuthController`, `UserController`, `ConfigController` → `@Context UriInfo` / `HttpHeaders` /
+     `io.vertx.core.http.HttpServerRequest`.
+   This unblocked the entire `@AutoJobPostMapping` chain (most PDF endpoints).
+
+4. **License singleton PK race** (`860bd6e63`). `UserLicenseSettings` has a manually-assigned
+   `@Id = 1L`. Spring Data `save()` on a non-new (pre-set-id) entity does a **MERGE (upsert)**; the
+   migration converted it to `persist()` (INSERT-only). The startup license sync raced the first
+   request, both inserted id=1 → `JdbcSQLIntegrityConstraintViolationException` → app crash. **Fixed**
+   in `UserLicenseSettingsService.getOrCreateSettings()` with a JVM lock +
+   `io.quarkus.narayana.jta.QuarkusTransaction.requiringNew()` create-once, then reload into the
+   caller's tx. **⚠️ This `save()`→`persist()`-should-be-`merge()` bug almost certainly exists for
+   OTHER manually-`@Id`'d entities — audit them (see §5).**
+
+5. **App couldn't boot without Redis** (`4665cceeb`).
+   - `quarkus.oidc.enabled=false` default (quarkus-oidc aborts startup without `auth-server-url`;
+     re-enable for an OAuth2 deployment).
+   - Valkey backplane beans eagerly injected the inactive `RedisDataSource`. Gated all 7 with
+     **build-time** `@io.quarkus.arc.properties.IfBuildProperty(name="cluster.backplane", stringValue="valkey")`
+     (NOT `@LookupIfProperty` — that leaves the bean in the build, so `RedisDataSource` still has a
+     consumer and Quarkus emits an eager startup observer that fails). Plus
+     `quarkus.redis.health.enabled=false`.
+
+6. **Runtime boot fixes** (`20b25ad76`): `quarkus.hibernate-orm.mapping.format.global=ignore` (JSON
+   columns), Quartz cron `0 0 0 * * MON` → `0 0 0 ? * MON` (Quartz rejects `*` in both day fields),
+   `@Scheduled(every="7d")` → `"P7D"`, `quarkus.arc.fail-on-intercepted-private-method=false`.
+
+7. **CDI augmentation** (`185ac88b3`): interceptor bindings made `@InterceptorBinding`
+   (`@EnterpriseEndpoint`, `@PremiumEndpoint`), a `tools.jackson.databind.ObjectMapper` producer
+   added in `AppConfig` (92 injection points), ambiguous beans resolved (`@DefaultBean`),
+   `Optional<X>`→`Instance<X>`, collection `List<X>`→`@All List<X>`, nested `SAML2` config producer.
+
+8. **Test layer** (`d51228af6`): a content-based exclude in root `build.gradle subprojects` skips any
+   test still importing `org.springframework`/`com.nimbusds` (self-maintaining), plus an explicit
+   list for tests asserting changed production signatures.
+
+---
+
+## 5. Recurring patterns / gotchas (apply these everywhere)
+
+- **HttpServletRequest is poison on reactive threads.** ~35 main-source files still reference
+  `HttpServletRequest` (see §6 list). For each in the request path, replace with:
+  - path/URI → `@Context jakarta.ws.rs.core.UriInfo` (`uriInfo.getRequestUri().getPath()`), or in a
+    non-JAX-RS bean inject `io.quarkus.vertx.http.runtime.CurrentVertxRequest`
+    (`currentVertxRequest.getCurrent().request().path()`), guarded in try/catch returning null/"".
+  - headers → `@Context jakarta.ws.rs.core.HttpHeaders` (`getHeaderString(name)`).
+  - remote addr / method → `@Context io.vertx.core.http.HttpServerRequest`.
+  - request attributes (`get/setAttribute`) → Vert.x `RoutingContext.get/put` via `CurrentVertxRequest`.
+  - In services that already have a guarded accessor, reuse `AuditService.getCurrentRequest()`.
+- **Spring `save()` → Panache:** if the entity uses `@GeneratedValue` (new on insert) → `persist()`.
+  If the entity has a **manually-assigned `@Id`** (caller sets the id, "upsert" semantics) →
+  `getEntityManager().merge()` (NOT `persist()`), and consider concurrency.
+- **Config gating:** runtime selection that must REMOVE a bean (so its deps don't get wired) →
+  build-time `@IfBuildProperty`/`@UnlessBuildProperty`. `@LookupIfProperty` only disables *lookup*,
+  the bean and its injection points stay in the build.
+- **`quarkus.*` build-time props** (e.g. `quarkus.oidc.enabled`, `quarkus.hibernate-orm.*`,
+  `quarkus.arc.*`) can't be overridden by env at runtime — they require a rebuild.
+- **settings.yml binding is suspect** (see maxDPI). Audit `ApplicationProperties` for primitive
+  fields that need non-zero/template defaults, and verify the settings.yml → ApplicationProperties
+  binding path actually works in Quarkus (it was Spring `@ConfigurationProperties` + a custom YAML
+  property source — see the `YamlPropertySourceFactory` / `ConfigInitializer` TODOs).
+- **Augment gate:** `compileJava` passing ≠ working. `./gradlew :stirling-pdf:quarkusBuild` surfaces
+  CDI wiring errors; only *running* surfaces the `UT000048` / config / race bugs. Always run.
+- **Jackson 2 vs 3 coexist:** ~100 files use `tools.jackson` (Jackson 3, from Spring Boot 4); REST
+  (de)serialization uses Quarkus' Jackson 2. Don't "fix" `tools.jackson` imports — there's a producer.
+
+---
+
+## 6. REMAINING WORK (prioritized)
+
+### A. Make the e2e Docker build first-class
+- [x] **DONE (Session 2):** `docker/quarkus/Dockerfile` (+ `README.md`, `build-and-run.sh`) committed,
+      uses the runner-jar, copies fonts; `.dockerignore` re-includes `app/core/build/*-runner.jar`.
+- [ ] Rewrite/replace `docker/embedded/Dockerfile`, `Dockerfile.fat`, `Dockerfile.ultra-lite` for
+      Quarkus: drop the Spring-Boot `-Djarmode=tools extract --layers` + `spring-boot-loader` layer
+      copies; either copy the uber `-runner.jar` to `/app/app.jar` or use the Quarkus fast-jar
+      (`quarkus-app/`) layout. The stage-1 `gradle clean build -PbuildWithFrontend=true` still builds
+      the frontend (fine).
+- [ ] Update `scripts/init.sh` / `init-without-ocr.sh` — they have Spring-loader fallbacks and AOT
+      machinery; the primary `java -jar /app.jar` path works for the uber-jar, but verify the AOT
+      cache + `restart-helper.jar` paths.
+- [ ] Then `testing/test.sh` (the official cucumber driver) should work end-to-end.
+
+### B. Real per-endpoint bugs surfaced by cucumber (login-off suite)
+Last measured failure buckets (before the transferTo/maxDPI fixes — re-run to refresh):
+- [ ] **`PdfCorruptedException` (~48)** on `convert/pdf/{word,vector,presentation,text,pdfa,...}`,
+      `convert/{html,cbz}/pdf`. Investigate `CustomPDFDocumentFactory` (PDF loading) — is it
+      misreporting valid PDFs as corrupted, or do these convert paths need LibreOffice/handling that
+      errors first and gets wrapped? Check one: `python -m behave features/convert_new.feature:NN --format plain`
+      then read `docker logs sp-e2e` for the real cause.
+- [ ] **`ClassCastException: String cannot be cast to ...` (~6)** — form/param binding type mismatch.
+      Likely a `@RestForm`/`@QueryParam` bound to the wrong type, or a Map/JSON form field. Check
+      `form/fill`, `form_advanced.feature`.
+- [ ] **Remaining `500`s** after A/B fixes — `misc/compress-pdf`, `general/split-pdf-by-chapters`,
+      `misc/add-image`, etc. Triage each via container logs.
+- [ ] **`400`s (~5)** — multipart `@RestForm` binding gaps. The migration left several request DTOs
+      with `MultipartFile`/POJO-list fields not bound to RESTEasy `FileUpload` (AI/workflow/sign DTOs
+      explicitly flagged). See `migration-report.md` "Representative deferred code".
+- [ ] **temp-file collisions other than transferTo** — also check `GeneralUtils.createTempFile`
+      (`app/common/.../util/GeneralUtils.java:79/85`) and any `Files.createFile`/`Files.copy`/
+      `Files.move` without `REPLACE_EXISTING`. `temp<rand>genericNonCustomisableName.pdf` and
+      `/tmp/stirling-pdf/stirling-pdf-<rand>.pdf` were two such names.
+
+### C. Background scheduled-task errors (log noise, not request-breaking)
+- [ ] `FolderWatchTrigger` (reconcile) and `ScheduleTrigger` (sweep) throw
+      `jakarta.enterprise.context.ContextNotActiveException` ("neither a transaction nor a CDI
+      request context is active") because they hit Panache/`PolicyRepository` off-request. Add
+      `@Transactional` (and/or `@ActivateRequestContext`) to those scheduled methods, or wrap the EM
+      access in `QuarkusTransaction.requiringNew()`. Files:
+      `app/proprietary/.../policy/trigger/FolderWatchTrigger.java`,
+      `.../policy/trigger/ScheduleTrigger.java`, `.../policy/store/JpaPolicyStore.java`.
+
+### D. The remaining ~35 `HttpServletRequest` files (apply §5 pattern as they surface)
+Not all are in the hot path; fix the ones that throw `UT000048` when their endpoints are exercised.
+Get the list any time with:
+```bash
+grep -rln "HttpServletRequest" app/core/src/main app/proprietary/src/main app/common/src/main --include=*.java
+```
+Known-fixed already: GlobalExceptionHandler, ControllerAuditAspect, AuditAspect, AutoJobAspect,
+JobExecutorService, AuthController, UserController, ConfigController. Everything else is unverified.
+High-risk: security filters (`UserAuthenticationFilter`, rate-limit filters, `JwtAuthenticationFilter`),
+anything reading headers/cookies/remote-addr per request.
+
+### E. Auth / JWT / login — DONE (Session 2)
+The whole Quarkus auth-identity layer is now in place (`app/proprietary/.../security/identity/`):
+- [x] **JWT Bearer** → `JwtBearerAuthenticationMechanism` + `JwtTokenIdentityProvider` (validate via
+      `JwtService`, map `role` claim). Run with `V2=true`.
+- [x] **X-API-KEY** → `ApiKeyAuthenticationMechanism` + `ApiKeyAuthenticationRequest` +
+      `ApiKeyIdentityProvider` (resolve via `userService.getUserByApiKey`). Lets `X-API-KEY` requests
+      authenticate (e.g. `/me`), and lets the suite run `SECURITY_ENABLELOGIN=true`.
+- [x] **User-as-principal** → `UserSecurityIdentityAugmentor` re-loads the `User` and sets it as the
+      `SecurityIdentity` principal; `User implements Principal`. This satisfies the ~7
+      `principal instanceof User` sites (folders, file storage, sessions, audit, UserController) — the
+      augmentor every `// TODO: Migration required` in security/storage asked for.
+- [x] **Config binding** → `ApplicationPropertiesConfigOverlay` overlays env/config onto
+      `ApplicationProperties` at startup (the Spring `@ConfigurationProperties` bind was never
+      migrated, so `SECURITY_ENABLELOGIN` / `SECURITY_CUSTOMGLOBALAPIKEY` / `STORAGE_ENABLED` were
+      ignored — root cause of the maxDPI/loginAttemptCount class too). **Currently a focused subset
+      (auth/storage/SSO toggles); a complete generic bind (all ~445 fields + settings.yml) is still
+      TODO.**
+- Validated on a login-ON probe (`SECURITY_ENABLELOGIN=true V2=true STORAGE_ENABLED=true
+  SECURITY_CUSTOMGLOBALAPIKEY=123456789`): open PDF endpoints (anon), JWT login+/me, X-API-KEY /me,
+  folder list/create all work. The 183 open endpoints stay open (no global `quarkus.http.auth.*`
+  policy), so login-ON does not regress them.
+
+### F. SAML / SSO — DONE (Session 2), both flows work end-to-end
+
+**Both `validate-oauth-test.sh` and `validate-saml-test.sh` pass, and both full login flows were
+verified end-to-end against the Keycloak compose** (login -> IdP -> callback/ACS -> auto-created
+user -> app JWT cookie -> `/me` 200). Run with `PREMIUM_KEY=<your enterprise license key>`. Tag the Quarkus image as
+`docker.stirlingpdf.com/stirlingtools/stirling-pdf:latest` so the compose uses it (or repoint the
+`image:`); `start-saml-test.sh` generates the SP certs + fetches Keycloak's cert.
+
+- **OAuth2 / OIDC** (`security/oauth2/`): `OAuth2LoginController` (JAX-RS) serves
+  `/oauth2/authorization/{id}` -> IdP authorize redirect; `OAuth2CallbackServlet` (`@WebServlet
+  /login/oauth2/code/*`) does the code exchange + userinfo + auto-create + JWT cookie. **Why a
+  servlet for the callback:** quarkus-undertow's default servlet owns the `/login/*` prefix and
+  query-strips/intercepts the extension-less callback before RESTEasy sees it; a registered
+  `@WebServlet` takes precedence. (Same reason the SAML SP endpoints are servlets.)
+- **SAML2** (`security/saml2/`): `Saml2Service` (OpenSAML 5) initialises the library, loads SP
+  key/cert + IdP cert, builds SP metadata, builds+signs the redirect-binding AuthnRequest, and
+  validates the SAMLResponse signature (`SAMLSignatureProfileValidator` + `SignatureValidator`
+  against the IdP cert). `SamlMetadataServlet` -> `/saml2/service-provider-metadata/{id}`;
+  `SamlSpServlet` -> `/saml2/authenticate/{id}` (login init) + `/login/saml2/sso/{id}` (ACS).
+  **Gotcha:** the SP entityId must equal the SP-metadata URL (`{backendUrl}/saml2/service-provider-
+  metadata/{id}`), which is what Keycloak's SAML client is keyed on - NOT the bare
+  `SECURITY_SAML2_SP_ENTITYID` host (`SamlConfig` derives it). Keycloak's realm has
+  `saml.client.signature=false` (AuthnRequest signature optional) + `saml.server.signature=true`
+  (so the ACS validates the response against Keycloak's cert).
+- Both flows finish by issuing the app JWT as the `stirling_jwt` cookie, which
+  `JwtBearerAuthenticationMechanism` now also reads (not just the `Authorization` header) -> feeds
+  the `UserSecurityIdentityAugmentor` (principal = User).
+- Follow-ups: logout/SLO endpoints; encrypted-assertion handling; the `mcp` Keycloak compose;
+  desktop/Tauri RelayState (`TauriSamlUtils` preserved). Multi-provider (google/github) OAuth uses
+  the same pattern keyed by registrationId.
+
+### F-old. (superseded) original SAML/SSO scoping
+The `validate-*-test.sh` scripts are **endpoint-existence
+checks** (Keycloak up + Stirling serves the SSO endpoint), not full browser logins.
+
+Prereqs for any run: the compose files use `image: docker.stirlingpdf.com/.../stirling-pdf:latest`
+(the published Spring image) — **repoint to `stirling-pdf-quarkus:jwt`** (or wire
+`docker/quarkus/Dockerfile`). The SAML compose mounts `saml-private-key.key`/`saml-public-cert.crt`/
+`keycloak-saml-cert.pem` which **do not exist in the repo** — generate them (the SP signing
+key/cert; `start-saml-test.sh` may do this). SAML/OAuth need the **Enterprise license** env.
+
+**OAuth2 / OIDC** (more tractable — Quarkus has `quarkus-oidc`):
+- [ ] Extend `ApplicationPropertiesConfigOverlay` for `security.oauth2.*` (client issuer/clientId/
+      clientSecret/scopes/useAsUsername) — currently only the `enabled` toggle is bound.
+- [ ] Serve `GET /oauth2/authorization/{registrationId}` → 302 to the IdP authorize URL (login
+      initiation; the OAuth `validate` script checks this responds). Build from issuer + clientId +
+      redirect-uri `/login/oauth2/code/{registrationId}`.
+- [ ] Serve the callback `GET /login/oauth2/code/{registrationId}` → exchange code (REST Client to
+      the token endpoint), fetch userinfo, auto-create/login the user (reuse `CustomOAuth2UserService`
+      logic), issue the app JWT via `JwtService`. `quarkus.oidc.enabled` is **build-time** and aborts
+      startup with no `auth-server-url`, so either hand-roll the flow (simplest, no build-time gate)
+      or enable oidc with a runtime-disabled default tenant.
+
+**SAML2** (larger — no Quarkus SAML extension; OpenSAML 5 from scratch):
+- [ ] `Saml2Configuration` already loads the SP/IdP certs and computes entityId/ACS/SLO URLs and
+      customizes the AuthnRequest (all preserved). Build on it:
+  - [ ] `GET /saml2/service-provider-metadata/{registrationId}` → SP `EntityDescriptor` XML
+        (ACS=`/login/saml2/sso/{id}`, SP signing cert) marshalled via OpenSAML 5. (The SAML `validate`
+        script checks this.)
+  - [ ] login initiation → build+sign an `AuthnRequest` (use `customizeAuthnRequest`) and
+        redirect/POST to `samlConf.getIdpSingleLoginUrl()`.
+  - [ ] `POST /login/saml2/sso/{registrationId}` (ACS) → validate the SAML response/assertion against
+        the IdP cert, extract the NameID/attributes, auto-create/login the user, issue the app JWT.
+  - Host these as Jakarta `@WebServlet` (quarkus-undertow) or JAX-RS resources; gate on
+        `security.saml2.enabled`.
+- [ ] Both flows then feed the existing `UserSecurityIdentityAugmentor` (principal=User) once they
+      establish the session/JWT.
+
+### G. `saas` flavor full augmentation (optional, non-default)
+- [ ] `STIRLING_FLAVOR=saas ./gradlew :stirling-pdf:quarkusBuild` → ~28 Arc deployment problems
+      (Supabase second datasource via `quarkus.datasource."supabase".*`, `SecurityFilterChain`/
+      `JwtDecoder` → `quarkus.http.auth.*`+OIDC, credit `HandlerInterceptor`/`@RestControllerAdvice`
+      → JAX-RS `@Provider`/`ExceptionMapper`, `@ConfigurationProperties` → `@ConfigMapping`,
+      RestTemplate → REST Client). ~90 `// TODO: Migration required` across 34 saas files.
+
+### H. Test suite (unit/integration) re-enablement
+- [ ] ~180 test files are excluded from compilation (content filter on `org.springframework`/
+      `com.nimbusds` imports + an explicit list in `build.gradle`). Port them to `@QuarkusTest`
+      incrementally; as a file's Spring imports go away it auto-re-enters the build.
+
+### I. Loose ends
+- [ ] `/q/openapi` returns 500 (`UT000048`) — known quarkus-undertow + smallrye-openapi interaction;
+      swagger-ui works, live API works. Affects API-doc tooling only.
+- [ ] Jackson 2/3 convergence (drop `tools.jackson`).
+- [ ] ~437 `// TODO: Migration required` markers across the codebase document every deferred decision;
+      `grep -rn "TODO: Migration required" app/*/src/main` to enumerate.
+
+---
+
+## 7. Quick reference — env vars used in e2e
+
+| Var | Value | Why |
+|-----|-------|-----|
+| `SECURITY_ENABLELOGIN` | `false` | run without auth (most API tests); set `true` for the JWT suite |
+| `METRICS_ENABLED` | `true` | enables `/api/v1/info/*` (info.feature) |
+| `SYSTEM_DEFAULTLOCALE` | `en-US` | matches default-language change |
+| `SYSTEM_MAXFILESIZE` | `100` | upload limit for tests |
+| `QUARKUS_HTTP_PORT` | `8080` | cucumber steps hardcode 8080 |
+| `QUARKUS_DATASOURCE_JDBC_URL` | `jdbc:h2:mem:...` | use a fresh in-mem DB for clean runs (avoids stale H2 file lock) |
+
+Default datasource (in `application.properties`) is **H2 file** at
+`./configs/stirling-pdf-DB-2.3.232` — fine in a container; for repeated host runs override to
+`jdbc:h2:mem:...` to dodge the file lock (`Database may be already in use`).
+
+---
+
+## 8. Useful diagnostic one-liners

+
+## 9. Measured cucumber results — newest first
+
+**Run 5 — LOGIN ON (`SECURITY_ENABLELOGIN=true V2=true STORAGE_ENABLED=true
+SECURITY_CUSTOMGLOBALAPIKEY=123456789`):**
+```
+18 features passed, 7 failed, 0 skipped
+304 scenarios passed, 34 failed, 0 skipped     <-- folders + user-scoped features now pass
+```
+X-API-KEY mechanism + User-principal augmentor + config overlay made login-ON work without
+regressing the open endpoints (0 folder failures). Trajectory: **183 → 223 → 272 → 291 → 304**.
+
+**Run 4 — login off + lockout fix:** `291 passed, 47 failed, 0 skipped`.
+
+**Run 3 — login off + `V2=true` + JWT Bearer mechanism (Session 2):**
+```
+17 features passed, 8 failed, 0 skipped
+272 scenarios passed, 66 failed, 0 skipped     <-- 0 skipped: all JWT/admin scenarios now run
+```
+The JWT mechanism unskipped all 80 and added +49 passing over run 2 with no regressions. Remaining
+66 failures, biggest buckets:
+- **~38 = login-lockout cascade (FIXED, pending re-measure).** `loginAttemptCount` defaulted to 0
+  (template = 5) → admin locked after one failed-login test → every later admin scenario blocked
+  ("Admin login failed" 21×, "Folder list returned" 17×). Fixed the primitive default (same as
+  maxDPI). **Re-run to confirm; expect ~300+.**
+- 10×(200→403) feature-gated/disabled (mostly not bugs).
+- 5×(200→401) + 2×(401→403) — auth scenarios asserting specific codes; triage individually.
+- 3×(200→500) — real per-endpoint bugs (e.g. `user/get-api-key`). Triage via container logs.
+
+**Run 2 — login off, Session 2 fixes, no JWT mechanism:**
+```
+16 features passed, 5 failed, 4 skipped
+223 scenarios passed, 35 failed, 80 skipped
+```
+
+**Run 1 — original baseline (login off):**
+```
+183 scenarios passed, 75 failed, 80 skipped
+```
+
+Trajectory this session: **183 → 223 (boot/login/test fixes) → 272 (JWT mechanism), 0 skipped.**

+ * Binds MicroProfile/Quarkus config (env vars, {@code settings.yml} via {@link
+ * SettingsYamlConfigSource}, {@code application.properties}, system properties) onto the mutable
+ * {@link ApplicationProperties} bean at startup - the Quarkus replacement for the Spring
+ * {@code @ConfigurationProperties(prefix = "")} relaxed binding that was lost in the migration.
+ *
+ * <p>Rather than hand-listing each property, this walks the whole {@code ApplicationProperties}
+ * object graph by reflection and, for every scalar / enum / scalar-list field, applies the value
+ * from config when one is present (so unset fields keep their Java default). The dotted key for a
+ * field mirrors its path in the tree ({@code security.oauth2.client.keycloak.clientId}, {@code
+ * endpoints.toRemove}, ...); SmallRye then resolves it from any source - e.g. env var {@code
+ * SECURITY_OAUTH2_CLIENT_KEYCLOAK_CLIENTID} or the same key in {@code settings.yml} - with the
+ * usual precedence (sys props &gt; env &gt; settings.yml &gt; application.properties).
+ *
+ * <p>This is the behaviour Spring had: every settings.yml / {@code SECURITY_*}/{@code STORAGE_*}
+ * /{@code PREMIUM_*} value is honoured, fixing the whole {@code maxDPI=0} / {@code enableLogin}
+ * /{@code endpoints.toRemove} / premium-license class of "ignored config" bugs at once.
+ *
+ * <p>Runs with {@code @Priority(APPLICATION)} so it completes before startup consumers read the
+ * bean: {@code InitialSecuritySetup} (enableLogin / customGlobalAPIKey), {@code
+ * EndpointConfiguration} (endpoints.toRemove), and {@code LicenseKeyChecker.onApplicationReady}
+ * (premium.enabled / premium.key, which has the lower default observer priority 2500).
+ *
+ * <p>Values are never logged - only key names at DEBUG and a total at INFO - because the tree
+ * carries secrets (premium key, client secrets, initial-login password, SMTP/Telegram tokens).

+ * like {@code security.enableLogin} fell back to their Java defaults regardless of the file (the

+ * YAML is flattened to dotted keys ({@code security.enableLogin -> "true"}); {@link
+ * ApplicationPropertiesConfigOverlay} and {@code @ConfigProperty} injections then read them.
+ *
+ * <p>Ordinal {@value #ORDINAL} sits above {@code application.properties} (250) but below
+ * environment variables (300) and system properties (400), matching Spring's precedence - e.g.
