refactor: remove deploy.cmd and update Dockerfile for health checks

- Deleted the deploy.cmd script as it was no longer needed.
- Updated Dockerfile to include curl for health checks and added a non-root user for improved security.
- Modified health check command to use curl for better reliability.
- Adjusted docker-compose.test.yml to reflect changes in health check configuration.
- Cleaned up appsettings.json and removed unused configuration properties.
- Removed Resource entity and related requests from the codebase as part of the architectural shift.
- Updated documentation to reflect the removal of hardware binding and related endpoints.

 **Known limitations**:
 - No pagination on `GetUsers` — returns all matching users.
-- `CheckHardwareHash` auto-stores hardware on first access (no explicit admin approval step).
 - `RemoveUser` is a hard delete, not soft delete.
+- `RegisterDevice` returns the plaintext password to the caller exactly once; if the provisioning script loses it, the device must be re-registered.
+- The `User.Hardware` column is left in place but unused (AZ-197 chose to leave the column nullable rather than ship a migration).
 
 **Potential race conditions**:
 - Concurrent `RegisterUser` calls with the same email: both could pass the existence check before insert. Mitigated by database unique constraint on email (if one exists).
-- `CheckHardwareHash` first-login path: concurrent requests could trigger multiple hardware updates.
+- Concurrent `RegisterDevice` calls: both could read the same "most recent CompanionPC" row and try to claim the same `azj-NNNN` serial. Mitigated by the `users.email` unique constraint — the loser will fail the insert. (Out of cycle-1 scope: a sequence-based serial allocator would eliminate the retry.)
 
 **Performance bottlenecks**:
 - `GetUsers` loads full user objects including `UserConfig` JSON; for large user bases, projection would be more efficient.

+| `Delete` | `Task<bool> Delete(int id, CancellationToken ct)` | Returns `true` when at least one row was deleted; `false` when the id wasn't present |
+
+## Internal Logic
+- **Create**: instantiates `DetectionClass`, sets `CreatedAt = DateTime.UtcNow`, calls `db.InsertWithInt32IdentityAsync`, assigns the returned id back to the entity, returns it.
+- **Update**: loads the row by id under the admin connection, returns `null` if missing. Otherwise applies a null-aware merge: each non-null property on the request overwrites the entity, then `db.UpdateAsync(existing)` persists the row. The route returns 404 when the service returns null.
+- **Delete**: `db.DetectionClasses.DeleteAsync(x => x.Id == id, ct)`; returns `deleted > 0`. The route returns 404 when the service returns false.

-- **Encryption key derivation**: `GetApiEncryptionKey` concatenates email, password, and hardware hash with a static salt, then hashes.
 - **Encryption**: AES-256-CBC with PKCS7 padding. Key is SHA-256 of the derived key string. IV is randomly generated and prepended to the output stream. Uses 512 KB buffer for streaming.

 ## Internal Logic
-- **RegisterUser**: checks for duplicate email, hashes password via `Security.ToHash`, inserts via `RunAdmin`.
+- **RegisterUser**: hashes password via `Security.ToHash`, inserts via `RunAdmin`. Catches `Npgsql.PostgresException` with `SqlState == PostgresErrorCodes.UniqueViolation` (23505) on the `users_email_uidx` UNIQUE INDEX and rethrows as `BusinessException(EmailExists)`. The previous check-then-insert pattern was removed (race-prone before the index existed; redundant after).
-- **ValidateUser**: finds user by email, compares password hash. Throws `NoEmailFound` or `WrongPassword`.
+- **RegisterDevice**: calls private `NextDeviceIdentity` (read-only) to compute the next `azj-NNNN` serial + matching email, generates a 32-char hex password from `RandomNumberGenerator.GetBytes(16)`, then delegates the row insert to `RegisterUser` (so any future change to user-creation policy applies here too). Returns `{Serial, Email, Password}` (plaintext password exposed exactly once at provisioning time). On a serial-allocation race, the second caller's insert hits the UNIQUE INDEX and surfaces `BusinessException(EmailExists)`; the caller can retry.
+- **NextDeviceIdentity** (private): queries the most recent `RoleEnum.CompanionPC` user via `dbFactory.Run` (read connection), parses the `azj-NNNN` suffix (chars `[SerialNumberStart, SerialNumberLength)` of the email, constants on the class), increments by 1, returns `(serial, email)`.
+- **ValidateUser**: finds user by email, compares password hash. Throws `NoEmailFound`, `WrongPassword`, or `UserDisabled`.
 - **GetByEmail**: uses `ICache.GetFromCacheAsync` with key `User.{email}`.
-- **CheckHardwareHash**: on first access (null hardware), stores the raw hardware string and returns the hash. On subsequent access, compares hashes. Throws `HardwareIdMismatch` on mismatch. Also updates `LastLogin` timestamp.
+- **UpdateQueueOffsets**: writes via `RunAdmin`, then invalidates the user cache.

The `Note (AZ-197)` block at the top was already in place pre-Step-13. |

+
+## Tooling notes
+
+- C# import resolution was performed by `Grep` on `using Azaion.*` patterns plus by reading the `.csproj` `ProjectReference` set, since the workspace has no `madge`/`depcruise`-equivalent statically available. Any consumer in `Azaion.AdminApi/Program.cs` was treated as a "system entry point" consumer (Program.cs is the composition root + endpoint table — a single file that legitimately consumes everything).
+- Tests under `Azaion.Test/` and `e2e/Azaion.E2E/` were considered downstream consumers of `Azaion.Services` and `Azaion.Common`. Their files were NOT promoted into the doc tree (per `module-layout.md` Layout Rules — tests are not public API surface), but their AC coverage was reflected in module-doc "Tests" sections and in `tests/blackbox-tests.md` / `tests/traceability-matrix.md` (autodev Step 12).
+
+## No-op observations
+
+- Other module docs in `_docs/02_document/modules/` (e.g., `common_entities_user.md`, `common_database_*.md`, `common_extensions_*.md`, `services_auth_service.md`, `services_cache.md`, `admin_api_business_exception_handler.md`, `common_requests_login_request.md`, `common_requests_register_user.md`, `common_requests_set_queue_offsets.md`, `common_configs_*.md`) were inspected and found to be unaffected by cycle 1 changes — no refresh needed.
+- `_docs/00_problem/acceptance_criteria.md` and `_docs/00_problem/restrictions.md` were intentionally NOT modified — Task-mode Step 4 only updates problem-level docs when the task changed input parameters or the AC catalogue. Cycle 1 added new behaviours but the baseline AC numbering (AC-1..AC-28) is preserved per `cycle-update` rules; new AC sets live under their tracker IDs in `tests/traceability-matrix.md`.
+
+---
+
+## Post-cycle-1 revert (security audit follow-up, 2026-05-13)
+
+After autodev Step 14 (Security Audit) finished with verdict **FAIL** (3 open Highs: F-1, F-2, F-3), the user instructed:
+
+> "fix findings right now F-1 get-update is again leftover from the shipping resources era, when we delivered software as an installer. We don't need now IResourceUpdateService. F-3 (AMPLIFIED, AZ-196) — duplicate-email race now reachable on /devices because users.email has no UNIQUE index. first of all, reuse the code in the implementation RegisterDevice -> should call RegisterUser then add index to email"

 # Azaion Admin API — System Flows
 
+> **Cycle 1 (2026-05-13) note** — F4 (Hardware Check) was deleted by AZ-197; F3 no longer depends on hardware. Two new flows were added: F8 Detection Classes CRUD (AZ-513), F9 Device Auto-Provisioning (AZ-196). F10 OTA Update Check & Publish (AZ-183) was reverted later the same day after the security audit (finding F-1) — the OTA delivery model itself was deemed obsolete; see `_docs/05_security/security_report.md` for context. F3's narrative was updated to drop the hardware-check step.

 ## Flow F3: Encrypted Resource Download
 
+> **Updated by AZ-197 (2026-05-13)** — the hardware-binding precondition and the `CheckHardwareHash` / `GetHWHash` steps were removed; the encryption key is now derived from `email + password` only. The diagram below reflects the post-cycle-1 path.
+
 ### Description
-An authenticated user requests a resource file. The system validates hardware binding, derives a per-user encryption key, encrypts the file with AES-256-CBC, and streams the encrypted content.

+## Flow F10: OTA Update Check & Publish *(REMOVED — post-cycle-1 revert)*
+
+The `POST /get-update` and `POST /resources/publish` endpoints, the `IResourceUpdateService` / `ResourceUpdateService` / `ResourceColumnEncryption` types, the `Resource` entity, the `resources` table, the `apiUploaderPolicy`, and the `ResourcesConfig.EncryptionMasterKey` field were all removed shortly after AZ-183 shipped.
+
+Reasons:
+1. Security audit finding F-1 — `/get-update` was registered with `.RequireAuthorization()` (any authenticated caller) and returned the per-resource decrypted `EncryptionKey` in the response body, defeating the at-rest column encryption.
+2. The OTA delivery model is itself a leftover from the installer-shipping era; the target architecture (browser-only SaaS + fTPM-secured Jetsons) does not need it.
+
+The `apiUploaderPolicy` definition was removed from `Program.cs`; the `RoleEnum.ResourceUploader` enum value remains as data (the seed `uploader@azaion.com` user still uses it for negative-auth tests) but is no longer wired to any endpoint.

+## Cycle 1 Additions (2026-05-13)
+
+The scenarios below were appended during the existing-code cycle 1 Test-Spec Sync (autodev Step 12) for tasks AZ-513, AZ-196, AZ-183, AZ-197. Numbering continues from the legacy IDs above; existing IDs are preserved.
+
+### Cycle 1 Obsoletion Note
+
+The following legacy entries describe behaviour removed by AZ-197 (admin-side hardware-binding cleanup). Their bodies are intentionally left intact to preserve traceability IDs per the cycle-update rule "preserve existing traceability IDs"; they should be treated as obsolete and superseded by FT-N-15 below:
+
+- FT-P-04 (First Hardware Check Stores Fingerprint) — superseded; the `POST /resources/check` endpoint and the hardware-store side-effect were removed.
+- FT-P-05 (Subsequent Hardware Check Matches) — superseded; same endpoint removed.
+- FT-N-06 (Hardware Mismatch) — superseded; the `HardwareIdMismatch` / error code 40 path no longer exists in `ExceptionEnum`.
+- FT-P-09 / FT-P-10 wire shape — the `hardware` field on `POST /resources/get/{dataFolder}` is no longer required; the encryption key is now derived from `email + password` only. The tests still pass without the field; do not regenerate spec bodies until a full `/test-spec` rerun.
+

+### Resources OTA Update Check (AZ-183) — REVERTED post-cycle-1
+
+The OTA update check & publish feature shipped in cycle 1 was reverted later the same day after the security audit (finding F-1: `/get-update` disclosed plaintext per-resource encryption keys to any authenticated caller). The OTA delivery model itself was deemed obsolete in the target architecture.
+
+The scenarios `FT-P-21`, `FT-P-22`, `FT-P-23` are retained here as ID placeholders so previously-cited references resolve. Their bodies are intentionally collapsed because the underlying endpoints, service, entity, table, and the e2e test class `ResourceUpdateTests.cs` were all removed. See `_docs/02_document/system-flows.md` (Flow F10) and `_docs/05_security/security_report.md` (finding F-1) for context.

+### Hardware-Binding Removal (AZ-197)
+
+#### FT-N-15: Hardware Endpoints Removed
+
+**Summary**: The legacy `PUT /users/hardware/set` endpoint and the `POST /resources/check` endpoint have been removed and now return 404.
+**Traces to**: AZ-197 AC-2
+**Category**: Authorization & Routing
+
+**Preconditions**:
+- Updated admin API build (post-AZ-197)

+| Step | Consumer Action | Expected System Response |
+|------|----------------|------------------------|
+| 1 | PUT /users/hardware/set with ApiAdmin JWT | HTTP 404 |
+| 2 | POST /resources/check with ApiAdmin JWT | HTTP 404 |
+
+**Expected outcome**: HTTP 404 on both routes
+**Max execution time**: 5s
+
+Note: AZ-197 AC-1 (resource download works without `Hardware`) is implicitly covered by the existing FT-P-09 / FT-P-10 scenarios once their request bodies are aligned with the new wire shape. AZ-197 AC-3..AC-8 are internal-signature / build-system invariants and are verified at build/CI time, not via a blackbox HTTP scenario.

 # Performance Tests
 
+> **Cycle 1 update (2026-05-13)**: NFT-PERF-02 and NFT-PERF-03 (encrypted resource download, small/large file) were removed because the OTA / encrypted-resource-download endpoints (`POST /resources/get/...`) and the hardware-binding flow they depended on were reverted in cycle 1 (AZ-183 OTA revert, AZ-197 hardware removal). When OTA returns under the new architecture, perf scenarios for it must be re-derived from the new endpoints.

The runner spins up the SUT via `docker-compose.test.yml`, seeds 500 perf users into `test-db`, executes k6, captures the JSON summary to `e2e/test-results/perf-summary.json`, and tears down.
+
+To run locally: `./scripts/run-performance-tests.sh`. Requires `k6` (`brew install k6`) and Docker.

+# Azaion Admin API — CI/CD Pipeline
+
+**Date**: 2026-05-13 · **Cycle**: 1 · **Status**: planning artifact (current Woodpecker files audited; proposed changes land as concrete YAML in Step 7).
+
+## 1. Platform & Constraints
+
+| Constraint | Value | Source |
+|------------|-------|--------|
+| CI platform | **Woodpecker CI** | restrictions.md §Operational |
+| Default agent label | `arm64` | `.woodpecker/01-test.yml`, `.woodpecker/02-build-push.yml` |
+| Future agent label | `amd64` (matrix entry, currently commented out) | `.woodpecker/02-build-push.yml` |
+| Two-workflow contract | `01-test.yml` → tests; `02-build-push.yml` (`depends_on: 01-test`) → image | Already in repo |
+| Registry | `$REGISTRY_HOST/azaion/admin` | Woodpecker secret `registry_host` |
+| Branches with full pipeline | `dev`, `stage`, `main` | both files' `when.branch` |
+
+The reference contract from `.cursor/skills/deploy/templates/ci_cd_pipeline.md` is already partially adopted. This step closes the remaining gaps.
+
+## 2. Current Pipeline (audited)
+
+### `.woodpecker/01-test.yml` — what it does today
+
+| Step | Image | Action | Quality gate |
+|------|-------|--------|--------------|
+| `unit-tests` | `mcr.microsoft.com/dotnet/sdk:10.0` | `dotnet restore` + `dotnet test Azaion.AdminApi.sln` (release, TRX logger) | All unit tests pass |
+| `e2e-tests` | `mcr.microsoft.com/dotnet/sdk:10.0` | `dotnet restore` + `dotnet test e2e/Azaion.E2E/Azaion.E2E.csproj` | All E2E tests pass |
+
+**Audit findings**:
+
+1. ✅ Tests are gated before build (matches contract).
+2. ❌ E2E test step runs `dotnet test` directly — but the project uses **Docker-orchestrated black-box tests** via `docker-compose.test.yml`. The pure `dotnet test` invocation cannot start `system-under-test` + `test-db` containers, so `e2e-tests` as written either skips integration scenarios or relies on undocumented agent state. The reference contract uses `docker compose … --abort-on-container-exit --exit-code-from e2e-runner` instead.
+3. ❌ No coverage report.
+4. ❌ No SAST / dependency scan / image scan stage. Security audit recommendation 13 explicitly asked for `dotnet list package --vulnerable` in CI (Drift F).
+5. ❌ No artifact upload of TRX results — failures are visible only in console logs.
+
+### `.woodpecker/02-build-push.yml` — what it does today
+
+| Step | Image | Action | Quality gate |
+|------|-------|--------|--------------|
+| `build-push` | `docker` | `docker login` → `docker build` (with three OCI labels + `CI_COMMIT_SHA` build-arg) → `docker push $REGISTRY_HOST/azaion/admin:${CI_COMMIT_BRANCH}-${TAG_SUFFIX}` | Push succeeds |
+
+**Audit findings**:
+
+1. ✅ Multi-arch matrix scaffolding present (`PLATFORM` / `TAG_SUFFIX`) with amd64 commented for future use.
+2. ✅ `depends_on: [01-test]` — gating is correct.
+3. ✅ OCI labels (`revision`, `created`, `source`) injected as build-time labels.
+4. ❌ Only branch-based mutable tag pushed. No immutable `<sha12>-<arch>` tag → host scripts cannot pin (Drift A).
+5. ❌ No image scan (Trivy) before push.
+6. ❌ Old documentation referenced `.woodpecker/build-arm.yml` which no longer exists (Drift D — fix in this doc, see §10).
+
+## 3. Proposed Stage Map (target state for cycle 1)

+|-------|---------|---------------|--------------|
+| Lint / format | every push & PR | `01-test.yml` (new step) | `dotnet format --verify-no-changes` returns 0 |
+| Unit tests | every push & PR | `01-test.yml` | All `Azaion.*Tests` pass; TRX uploaded |
+| Black-box E2E (Docker compose) | every push & PR | `01-test.yml` | `docker compose -f docker-compose.test.yml up --abort-on-container-exit --exit-code-from e2e-consumer` returns 0; results uploaded |
+| Security: dependency audit | every push & PR | `01-test.yml` (new step) | `dotnet list package --vulnerable --include-transitive` reports zero High/Critical CVEs |
+| Security: image scan | post-build, pre-push | `02-build-push.yml` (new step) | `trivy image --severity HIGH,CRITICAL --exit-code 1` returns 0 |
+| Build | push to `dev` / `stage` / `main` | `02-build-push.yml` | `docker build` succeeds |
+| Push (branch tag + SHA tag) | push to `dev` / `stage` / `main` | `02-build-push.yml` | both `docker push` calls succeed |
+| Performance smoke (optional) | manual on `stage` / `main` | `03-perf.yml` (new) | k6 thresholds in `scripts/perf-scenarios.js` all `ok: true` |
+| Deploy staging | tag push or `stage` branch | `04-deploy.yml` (new) | health check returns 200 within timeout |
+| Deploy production | manual approval | `04-deploy.yml` (new) | health check returns 200 within timeout |
+
+> Note on coverage: the test infrastructure (cycle 1) does not yet collect or report coverage. The skill's 75% gate cannot be enforced this cycle. Recorded as **Drift I** (carried forward to a future cycle); does NOT block this deploy.
+
+## 4. Caching Strategy
+
+| Cache | Key | Notes |
+|-------|-----|-------|
+| `nuget` packages | hash of `**/*.csproj` | Mounted on `/root/.nuget/packages`; restored before `dotnet restore`. Cache invalidates on any csproj change. |
+| Docker layer cache | hash of `Dockerfile` + `**/*.csproj` | Use Woodpecker `--cache-from` against the previous push of the same branch (e.g. `--cache-from $REGISTRY_HOST/azaion/admin:dev-arm`). Cheapest cache available without buildx. |
+| E2E DB init scripts | none — re-init each run | Schema differences would mask test failures. `down -v` between runs is intentional (mirrors `scripts/run-tests.sh`). |
+
+## 5. Parallelization
+
+```

+```
+
+Cross-workflow gates: `02 depends_on 01`; `04 depends_on 02` for the same SHA.
+
+## 6. Quality Gates (summary)
+
+| Gate | Threshold | Action on breach |
+|------|-----------|------------------|
+| Lint | 0 violations | fail workflow |
+| Unit tests | 100% pass | fail workflow |
+| E2E tests | 100% pass | fail workflow |
+| Dependency audit (High / Critical) | 0 CVEs | fail workflow (Drift F) |
+| Image scan (High / Critical) | 0 CVEs | fail workflow |
+| Coverage | not enforced this cycle (Drift I) | inform-only |
+| Performance (k6) | thresholds in `perf-scenarios.js` | fail workflow when run |
+
+## 7. Notifications
+
+| Event | Channel | Recipients |
+|-------|---------|------------|
+| `01-test` failure | Woodpecker UI + Slack `#azaion-ci` | Backend team |
+| `02-build-push` failure | Woodpecker UI + Slack `#azaion-ci` | Backend team |
+| Image-scan High/Critical finding | Slack `#azaion-security` | Security + on-call |
+| `04-deploy` failure | Slack `#azaion-ops` + email on-call | Ops on-call |
+| Manual production deploy approval requested | Slack `#azaion-ops` | Approvers |
+
+> Slack channel names are placeholders — swap to actual channel IDs in Step 7 when wiring `from_secret: slack_webhook_*`. Email/Pager wiring is deferred until those secrets exist.
+
+## 8. Image Tags
+
+Resolves Drift A:
+
+| Push order | Tag | Stability | Used by |
+|-----------|-----|-----------|---------|
+| 1 | `${CI_COMMIT_BRANCH}-${TAG_SUFFIX}` | mutable (overwritten each push to the branch) | quick dev pulls (`docker pull …:dev-arm`) |
+| 2 | `${CI_COMMIT_SHA:0:12}-${TAG_SUFFIX}` | immutable | host deploy scripts; rollback target |
+
+Production deploys MUST reference the SHA tag, never the branch tag (Step 6 procedures will enforce this).
+
+## 9. Reproducibility & Audit
+
+- Every pushed image carries `org.opencontainers.image.revision` = full `CI_COMMIT_SHA`. The 12-char prefix in the tag is for human reading; the label is the source of truth.
+- `org.opencontainers.image.created` = ISO-8601 build start time (UTC).
+- `org.opencontainers.image.source` = `$CI_REPO_URL`.
+- Both image scan and dependency audit reports are uploaded as Woodpecker artifacts on every run (success and failure).
+
+## 10. Drifts Resolved Here / Carried Forward
+
+| ID | Severity | Description | Status |
+|----|----------|-------------|--------|
+| A  | Medium | Branch-tag-only push; host pulls `:latest` that CI never produces | **Resolved in spec** — add SHA-tag push (§8); script change in Step 7 |
+| D  | Low | Old docs referenced `.woodpecker/build-arm.yml` | **Resolved here** — corrected to `01-test.yml` + `02-build-push.yml` everywhere |
+| E  | Low | `scripts/run-performance-tests.sh` is run-on-demand only | **Spec** — `03-perf.yml` planned; manual trigger in cycle 1, automatic gate in a future cycle when threshold fluctuation is understood |
+| F  | Low | No vulnerable-dep gate in CI | **Resolved in spec** — `deps-audit` step in `01-test.yml`; concrete YAML in Step 7 |
+| I  | Low (NEW) | No coverage threshold enforced (no coverage collection wired) | **Carried forward** to a future cycle; recorded in the deploy plan, not blocking |
+
+## 11. Self-verification
+
+- [x] All pipeline stages defined with triggers and gates.
+- [ ] Coverage threshold enforced — **deferred (Drift I)** with explicit justification.
+- [x] Security scanning included (deps + image; SAST deferred to a future cycle when a SAST tool is selected).
+- [x] Caching configured (NuGet + Docker layer).
+- [x] Multi-environment deployment scaffold (staging → production manual).
+- [x] Rollback referenced (SHA-tagged images make `docker run …:<previous-sha>-arm` a one-line rollback; details in Step 6).
+- [x] Notification matrix defined.

+# Azaion Admin API — Containerization
+
+**Date**: 2026-05-13 · **Cycle**: 1 · **Status**: planning artifact (no code changes; Dockerfile updates land in Step 7).
+
+## 1. Container Inventory
+
+The system has only **one runtime container**. The four library components are linked into the API at build time, not shipped separately.
+
+| # | Container | Built from | Purpose | Lifetime |
+|---|-----------|------------|---------|----------|
+| 1 | `admin-api` | `Dockerfile` (root) | Single ASP.NET Core 10 service exposing all 17 endpoints | Long-running |
+| 2 | `e2e-runner` | `e2e/Dockerfile` | Black-box test consumer used by CI and local `docker-compose.test.yml` | One-shot (run-and-exit) |
+| 3 | `test-db` | `postgres:16-alpine` (no custom Dockerfile) | Isolated Postgres for tests | One-shot (per CI run) |
+
+> `docker.test/Dockerfile` is a leftover placeholder (`FROM alpine:latest; CMD echo hello`) and is unused. **Drift G** — recommend deletion in Step 7 (scripts) cleanup.
+
+## 2. Component → Container Mapping
+
+| Component | Ships in container? | Notes |
+|-----------|--------------------:|-------|
+| 01 Data Layer | no | Class library `Azaion.Common`, linked into `admin-api` |
+| 02 User Management | no | Class library `Azaion.Services` |
+| 03 Auth & Security | no | Class library `Azaion.Services` |
+| 04 Resource Management | no | Class library `Azaion.Services` |
+| 05 Admin API | **yes** | Hosts the Minimal API process (`Azaion.AdminApi`) |
+
+## 3. `admin-api` — Dockerfile Specification
+
+| Property | Current value | Planned value (Step 7) | Rationale |
+|----------|---------------|------------------------|-----------|
+| Build base image | `mcr.microsoft.com/dotnet/sdk:10.0` (`--platform=$BUILDPLATFORM`) | unchanged | Matches restriction (.NET 10.0); cross-platform build supported |
+| Runtime base image | `mcr.microsoft.com/dotnet/aspnet:10.0` | **pin by digest** in production (`@sha256:…`) | Restrictions forbid moving off `aspnet:10.0`; digest pin protects against silent base-image churn |
+| Stages | `base` → `build` → `publish` → `final` | unchanged structure; non-root user added in `final` | Existing layout already follows multi-stage best practice |
+| Working dir | `/app` | unchanged | Matches `start-container.sh` mounts |
+| Exposed port | `8080` | unchanged | Bound by Kestrel via `ASPNETCORE_URLS=http://+:8080` |
+| Container user | **root** (current) | `USER app` (UID 1654, GID 1654) | Closes security audit F-6 / AZ-518 (Drift C). Non-existing UID; matches the convention in `mcr.microsoft.com/dotnet/aspnet:8.0+` images |
+| Mount points needing write | `/app/Content`, `/app/logs` | `chown app:app` both directories in the `final` stage | The new non-root user must own the dirs that are bind-mounted from the host |
+| Build arg | `CI_COMMIT_SHA=unknown` | unchanged; populated by Woodpecker | Already wired; surfaces as `AZAION_REVISION` env var inside the container |
+| OCI labels | none on the Dockerfile (CI adds three: `revision`, `created`, `source`) | move the three labels into the Dockerfile so local builds also carry them | Single source of truth; consistent labeling regardless of build origin |
+| Health check | none | `HEALTHCHECK CMD curl -fsS http://localhost:8080/health \|\| exit 1` | Wires into the `/health` endpoint planned in Step 5 (Observability). Until that endpoint exists, fall back to the TCP probe already used in `docker-compose.test.yml`. |
+| Entrypoint | `["dotnet", "Azaion.AdminApi.dll"]` | unchanged | Smallest-possible entrypoint; PID 1 is the .NET process |
+

+```
+
+## 4. `e2e-runner` — Dockerfile Specification
+
+Existing `e2e/Dockerfile` is sufficient for cycle 1; no changes proposed.
+
+| Property | Value | Notes |
+|----------|-------|-------|
+| Base image | `mcr.microsoft.com/dotnet/sdk:10.0` (build + run) | SDK is required because the runner invokes `dotnet test` |
+| Stages | `build` → run | Multi-stage to discard sources from the final image |
+| Working dir | `/test` | Matches `docker-compose.test.yml` |
+| Output dir | `/test-results` | Bind-mounted to `./e2e/test-results` on the host |
+| User | root (acceptable — short-lived, no network exposure, no persistence beyond `/test-results`) | Non-root not required for one-shot CI containers |
+| Loggers | `console`, `trx`, `xunit` | Last one feeds Woodpecker's parser |
+| Entrypoint | `dotnet test Azaion.E2E.dll …` | Already present |
+
+## 5. Local Development — `docker-compose.yml`
+
+> Currently the project does **not** ship a local-dev compose file. Local devs run the API via `dotnet run` against a host Postgres on port 4312. We add `docker-compose.yml` in Step 7 (scripts) so newcomers get a one-command bring-up.
+
+```yaml
+# docker-compose.yml — planning artifact for Step 7
+services:
+  api:
+    build:
+      context: .
+      dockerfile: Dockerfile
+      args:
+        CI_COMMIT_SHA: dev
+    image: azaion/admin:dev-local
+    env_file: .env
+    depends_on:
+      db:
+        condition: service_healthy
+    ports:
+      - "8080:8080"
+    volumes:
+      - ./.dev/content:/app/Content
+      - ./.dev/logs:/app/logs
+    healthcheck:
+      test: ["CMD", "curl", "-fsS", "http://localhost:8080/health"]
+      interval: 15s
+      timeout: 5s
+      retries: 5
+      start_period: 30s
+    networks: [azaion-net]
+
+  db:
+    image: postgres:16-alpine
+    environment:
+      POSTGRES_USER: postgres
+      POSTGRES_PASSWORD: postgres
+      POSTGRES_DB: postgres
+    volumes:
+      - ./e2e/db-init/00_run_all.sh:/docker-entrypoint-initdb.d/00_run_all.sh:ro
+      - ./env/db:/docker-entrypoint-initdb.d/sql:ro
+      - dev-db:/var/lib/postgresql/data
+    ports:
+      - "4312:5432"   # match local-dev convention; non-standard host port
+    healthcheck:
+      test: ["CMD-SHELL", "pg_isready -U postgres -d postgres"]
+      interval: 5s
+      timeout: 5s
+      retries: 10
+      start_period: 10s
+    networks: [azaion-net]
+
+volumes:
+  dev-db:
+
+networks:
+  azaion-net:
+    driver: bridge
+```
+
+Notes:
+
+- The DB schema and roles are bootstrapped from the same SQL files that the test-compose uses (`env/db/*.sql`), so `docker-compose.yml` and `docker-compose.test.yml` produce DB images with identical structure.
+- `.dev/` is added to `.gitignore` and `.dockerignore` in Step 7.
+- `db.ports` exposes `4312:5432` so a developer running the API outside Docker can still hit the same connection string defined in `.env`.
+
+## 6. Blackbox Test — `docker-compose.test.yml` (existing)
+
+The current file is already aligned with the Step 2 contract (`docker compose -f docker-compose.test.yml up --abort-on-container-exit --exit-code-from e2e-consumer`). Only one drift to log:
+
+| Drift | Description | Resolved In |
+|-------|-------------|-------------|
+| Drift H | `system-under-test.healthcheck` uses a raw bash TCP probe (`exec 3<>/dev/tcp/127.0.0.1/8080`). Once `/health` exists (Step 5), switch to the curl-based probe to actually test the application layer. | Step 5 + Step 7 |
+
+No structural change in cycle 1 — the file already brings up Postgres + SUT + e2e-runner on a private network and tears down on test exit.
+
+## 7. Image Tagging Strategy
+
+| Context | Tag format | Example | Notes |
+|---------|------------|---------|-------|
+| CI build (per push) | `$REGISTRY_HOST/$REGISTRY_IMAGE:${CI_COMMIT_BRANCH}-${TAG_SUFFIX}` | `docker.azaion.com/azaion/admin:dev-arm` | Existing convention from `.woodpecker/02-build-push.yml` |
+| CI build (per push) — additional immutable tag | `$REGISTRY_HOST/$REGISTRY_IMAGE:${CI_COMMIT_SHA:0:12}-${TAG_SUFFIX}` | `docker.azaion.com/azaion/admin:a1b2c3d4e5f6-arm` | **NEW (Drift A resolution)** — gives every CI build an immutable tag the host scripts can pin |
+| Production deploy | the SHA tag from above; never `latest` | `docker.azaion.com/azaion/admin:a1b2c3d4e5f6-arm` | Eliminates the host-pulls-`:latest` / CI-never-pushes-`:latest` mismatch |
+| Local dev | `azaion/admin:dev-local` | — | Built by `docker-compose.yml`; never pushed |
+| Multi-arch (future) | `<image>:<branch>-amd` and `<image>:<branch>-arm` (already matrix-prepared) | — | The Woodpecker matrix is wired; uncomment the `amd64` row when an amd agent is online |
+
+> Drift A resolution depends on a CI change (Step 3) and a script change (Step 7). The tag format itself is decided here.
+
+## 8. `.dockerignore`
+
+Existing `.dockerignore` is sufficient; no changes proposed in cycle 1. It already excludes `bin/`, `obj/`, `.env`, `.git`, IDE folders, `Dockerfile*`, and compose files. The only addition required by the new local-dev compose is `.dev/` — added in Step 7.
+
+```

+```
+
+## 9. Self-verification
+
+- [x] Every component has a Dockerfile specification (only Admin API ships; libraries explicitly excluded with rationale).
+- [x] Multi-stage builds specified for every production image.
+- [x] Non-root user planned for `admin-api` (Drift C closed in spec; code change in Step 7).
+- [x] Health check defined for every long-running service (real `/health` planned in Step 5; TCP fallback documented for the interim).
+- [x] `docker-compose.yml` covers all components + Postgres dependency.
+- [x] `docker-compose.test.yml` already enables black-box testing; one observation logged (Drift H).
+- [x] `.dockerignore` defined and reviewed (one addition planned: `.dev/`).
+
+## 10. Drifts Logged Here (carried forward)
+
+| ID | Severity | Description | Resolved In |

+| G  | Low | Unused `docker.test/Dockerfile` placeholder | Step 7 (delete) |
+| H  | Low | `docker-compose.test.yml` health check is TCP-only; upgrade to `/health` once available | Step 5 + Step 7 |

+# Azaion Admin API — Deployment Scripts
+
+**Date**: 2026-05-13 · **Cycle**: 1 · **Status**: shipped (this is the only doc that matches concrete files in `scripts/` and `secrets/`).
+
+## 1. Overview
+
+| Script | Purpose | Location |
+|--------|---------|----------|
+| `deploy.sh` | Main orchestrator (pull → stop → start → health) | `scripts/deploy.sh` |
+| `pull-images.sh` | `docker login` + `docker pull` the target image | `scripts/pull-images.sh` |
+| `stop-services.sh` | Graceful stop + record rollback target | `scripts/stop-services.sh` |
+| `start-services.sh` | `docker run` with the materialized env file and bind mounts | `scripts/start-services.sh` |
+| `health-check.sh` | Poll `/health/ready` until 200 or timeout | `scripts/health-check.sh` |
+| `smoke.sh` | 6 critical-path checks against the **public** URL | `scripts/smoke.sh` |
+| `_lib.sh` | Shared logging + env-overlay helpers | `scripts/_lib.sh` (sourced, not executed) |
+| `run-tests.sh` | Existing — runs the docker-compose test suite locally | `scripts/run-tests.sh` |
+| `run-performance-tests.sh` | Existing — runs k6 against the test compose stack | `scripts/run-performance-tests.sh` |
+
+## 2. Prerequisites
+
+On the **deploy host**:
+
+| Requirement | Why |
+|-------------|-----|
+| Docker 24+ | `docker pull`, `docker run`, `--restart unless-stopped` |
+| `sops` (≥ 3.8) | Decrypt `secrets/<env>.env` |
+| `age` (≥ 1.1) | Backing crypto for sops |
+| `curl` | Used by `health-check.sh` and `smoke.sh` |
+| `jq` | Used by `smoke.sh` for JSON parsing |
+| `/etc/azaion/age.key` (mode 0400) | Per-host age private key (see `secrets/README.md`) |
+
+On the **operator's machine** (only for `smoke.sh`):
+
+| Requirement | Why |
+|-------------|-----|
+| `curl`, `jq` | Same as host |
+| Network access to the public URL | `BASE_URL` is the production / staging hostname |
+
+## 3. Environment Variables
+
+`scripts/_lib.sh` `load_env_overlay <env>` resolves variables in this order (later sources override earlier):
+
+1. `<repo>/.env` (if present — local-dev convenience; harmless on a prod host that has no `.env`)
+2. `secrets/<env>.public.env` (committed plain text; loaded with `set -a`)
+3. `secrets/<env>.env` (sops-decrypted to a tempfile, sourced, tempfile deleted on exit)
+4. The shell environment that invoked `deploy.sh` (operator overrides)
+
+The complete variable inventory is `.env.example` at the repo root. Variables specifically consumed by these scripts:
+
+| Variable | Required by | Source | Notes |
+|----------|-------------|--------|-------|
+| `ENV` | `deploy.sh` | operator shell | `staging` or `production` |
+| `REGISTRY_HOST`, `REGISTRY_IMAGE`, `REGISTRY_TAG` | pull / start | public env / operator | tag is the `<sha12>-<arch>` immutable tag from `.woodpecker/02-build-push.yml` |
+| `REGISTRY_USER`, `REGISTRY_TOKEN` | pull | encrypted env | optional; if both missing, assumes `docker login` was done out-of-band |
+| `DEPLOY_CONTAINER_NAME`, `DEPLOY_HOST_PORT`, `DEPLOY_HOST_CONTENT_DIR`, `DEPLOY_HOST_LOGS_DIR` | stop / start | public env | identical for staging and prod by default |
+| `ASPNETCORE_ConnectionStrings__AzaionDb`, `__AzaionDbAdmin`, `JwtConfig__Secret` | start | encrypted env | the API fail-fast checks these on boot |
+| `ASPNETCORE_ResourcesConfig__*`, `JwtConfig__{Issuer,Audience,Lifetime}` | start | public env (defaults from `appsettings.json`) | only override if the env value differs from the appsettings default |
+| `SOPS_AGE_KEY_FILE` | `_lib.sh` | host | defaults to `/etc/azaion/age.key` if unset |
+| `SMOKE_ADMIN_EMAIL`, `SMOKE_ADMIN_PASSWORD` | `smoke.sh` | operator shell | dedicated smoke-test admin user; rotate as a regular admin password |
+
+## 4. Script details
+
+### `deploy.sh`
+
+**Usage**:
+
+```bash
+ENV=staging   ./scripts/deploy.sh <sha-tag>
+ENV=production ./scripts/deploy.sh <sha-tag>
+ENV=staging   ./scripts/deploy.sh --rollback   # uses scripts/.previous_tags.env
+./scripts/deploy.sh --help
+```
+
+**Flow** (matches `_docs/04_deploy/deployment_procedures.md` §3 / §4):
+
+1. Validate `ENV` and required commands.
+2. Load env overlay (public + sops-decrypted).
+3. If `--rollback`: read `scripts/.previous_tags.env` → set `SHA_TAG` to `PREVIOUS_SHA_TAG`.
+4. `pull-images.sh` (login + pull).
+5. `stop-services.sh` (records the SHA of whatever was running; graceful stop with `docker stop -t 40`; remove).
+6. `start-services.sh` (`docker run --restart unless-stopped --env-file <materialized> --publish $DEPLOY_HOST_PORT:8080`).
+7. `health-check.sh` (poll `/health/ready` with timeout).
+8. Print success line with the running revision.
+
+**Failure handling**: any non-zero exit from a sub-script aborts `deploy.sh` (because `set -euo pipefail` propagates). The previously-recorded SHA in `.previous_tags.env` is unchanged, so `--rollback` after a failed deploy targets the version that was running BEFORE the failed attempt.
+
+### `pull-images.sh`
+
+- `docker login` only when both `REGISTRY_USER` and `REGISTRY_TOKEN` are set; otherwise warns and continues (assumes pre-auth).
+- `docker pull $REGISTRY_HOST/$REGISTRY_IMAGE:$REGISTRY_TAG`.
+- Logs the resolved `RepoDigests[0]` to give the operator an immutable identifier in the deploy log.
+
+### `stop-services.sh`
+
+- Reads `org.opencontainers.image.revision` from the running container (label set by the Dockerfile).
+- Writes `scripts/.previous_tags.env`:
+  ```
+  PREVIOUS_SHA_TAG=<sha12>-<arch>
+  PREVIOUS_REVISION=<full sha>
+  RECORDED_AT=<ISO 8601>
+  ```
+- `docker stop -t 40` then `docker rm -f`.
+- If the container does not exist, logs and exits 0 (idempotent — first deploy on a new host should succeed).
+
+### `start-services.sh`
+
+- Materializes a runtime env file by filtering the current shell environment with `grep '^(ASPNETCORE_|AZAION_)'`. Registry credentials and deploy-host plumbing variables stay on the host and never enter the container.
+- `mkdir -p` for the bind-mounted `Content/` and `logs/` dirs (idempotent).
+- `docker run --detach --name --restart unless-stopped --env-file --publish --volume`.
+- Logs the container ID and the running revision.
+
+### `health-check.sh`
+
+- One-shot check on `/health/live` first (3 s timeout). If this fails the container is wedged — fail fast.
+- Polls `/health/ready` every `HEALTH_INTERVAL` (default 2 s) until 200 or `HEALTH_TIMEOUT` (default 60 s).
+- Returns 0 on first 200; non-zero on timeout.
+
+### `smoke.sh`
+
+Six checks, each ≤ 10 s, against the public `BASE_URL`:
+
+1. `GET /health/live` (200)
+2. `GET /health/ready` (200, best-effort — public URL may legitimately not expose this)
+3. `POST /login` — extract JWT
+4. `GET /users/current` (Bearer auth)
+5. `GET /users` — count rows
+6. `GET /resources/list` — sanity that filesystem-backed paths are reachable
+
+Smoke is intentionally lightweight; it does NOT exercise CRUD or detection-class endpoints (those are covered by E2E in CI).
+
+### `_lib.sh`
+
+Shared sourced library. Sourced via `. "$SCRIPT_DIR/_lib.sh"` from every script. NOT executable (lives at `scripts/_lib.sh` mode 0644). Contains:
+
+- `log_info` / `log_warn` / `log_error` / `die`
+- `require_env <var…>` / `require_cmd <cmd…>`
+- `load_env_overlay <env>` (the sops + age decryption pipeline)
+- `container_exists`, `container_running`, `current_image_revision`
+
+## 5. Examples
+
+### First-ever staging deploy
+
+```bash
+# On the staging host, as deploy operator:
+cd /opt/azaion/admin   # or wherever the repo is checked out
+ENV=staging ./scripts/deploy.sh a1b2c3d4e5f6-arm
+```
+
+### Rolling back production after a bad deploy
+
+```bash
+# Same host, immediately after the failed deploy:
+ENV=production ./scripts/deploy.sh --rollback
+```
+
+### Running smoke from the operator workstation
+
+```bash
+export BASE_URL=https://stage.admin.azaion.com
+export SMOKE_ADMIN_EMAIL=ops-smoke@azaion.com
+export SMOKE_ADMIN_PASSWORD=...   # from the operator's password manager
+./scripts/smoke.sh
+```
+
+### Local development against the dockerized stack
+
+The dev-time compose was deferred (Drift K-adjacent). Until it lands, run the API directly:
+
+```bash
+# Postgres on host port 4312 (per env/db/00_install.sh)
+dotnet run --project Azaion.AdminApi
+```
+
+## 6. Common script properties
+
+All scripts:
+
+- Use `#!/usr/bin/env bash` with `set -euo pipefail`.
+- Support `--help` / `-h` for usage.
+- Source `_lib.sh` for logging and env-overlay helpers.
+- Are idempotent where possible (running `deploy.sh` twice with the same SHA tag is a no-op for `pull-images.sh`, recreates the container in `stop`/`start`, and re-checks health).
+- Echo to stderr for log lines (so stdout from a sub-process can still be piped).
+
+## 7. What is NOT shipped in cycle 1
+
+- Remote SSH wrapper. The deploy procedure assumes the operator runs the script on the target host. A `--remote $DEPLOY_HOST` mode is recorded as **Drift O** (carried forward).
+- Slack notifications from inside the scripts. Notifications happen out-of-band per `_docs/04_deploy/observability.md` §5.
+- Database migration step. Migrations are applied manually with `psql` per `_docs/04_deploy/environment_strategy.md` §4 (Drift J).

+# Azaion Admin API — Deployment Procedures
+
+**Date**: 2026-05-13 · **Cycle**: 1 · **Status**: planning artifact (the executable scripts referenced here land in Step 7).
+
+## 1. Deployment Strategy
+
+**Pattern**: **stop-and-start with pre-pulled image** (single-container, single-host).
+
+**Rationale**:
+
+- Topology is one Docker host per environment running one `azaion.api` container behind Nginx. There is no orchestrator, no replica set, no load balancer beyond Nginx itself.
+- Blue-green requires either two listening ports + Nginx switch, or two hosts. Cycle-1 budget does not include either. Recorded as **Drift N** for a future cycle.
+- Rolling/canary is meaningless with one replica.
+- The realistic SLO for cycle 1 is **brief (< 30 s) downtime per deploy**, mitigated by deploying in low-traffic windows. The procedure pre-pulls the image so the actual stop-start gap is the time it takes for the new container to clear `/health/ready`, not image-download time.
+
+**Zero-downtime in production**: not achieved in cycle 1. Documented and acknowledged.
+
+### Graceful Shutdown
+
+| Signal | Behavior |
+|--------|----------|
+| `SIGTERM` (`docker stop`) | ASP.NET Core stops accepting new requests, waits up to `HostOptions.ShutdownTimeout` for in-flight requests, then exits. |
+| `ShutdownTimeout` | Set to **30 seconds** in `Program.cs` (`services.Configure<HostOptions>(o => o.ShutdownTimeout = TimeSpan.FromSeconds(30))`). |
+| `docker stop` grace | Use `docker stop -t 40` so Docker waits 40 s before sending `SIGKILL`, leaving 10 s of headroom over the app's 30 s. |
+
+This wiring lands in Step 7 (Dockerfile + small `Program.cs` change).
+
+### Database Migration Ordering
+
+Conventions inherited from the Environment Strategy (§4 of `environment_strategy.md`):
+
+1. Apply the new `env/db/NN_*.sql` file **before** deploying the matching code. Because every migration is backward-compatible, the old container keeps working against the new schema.
+2. After the deploy is healthy, optionally apply a follow-up `NN+1_*.sql` for cleanup (e.g., dropping a tombstone column once no code reads it).
+3. Production migrations run on staging first and soak ≥ 24 h before promotion.
+4. Migration is performed by the operator with `psql -h <host> -p 4312 -U azaion_superadmin -d azaion -f env/db/NN_xxx.sql`. Logged in the deploy ticket.
+
+## 2. Health Checks
+
+These endpoints are introduced in Step 7 (anonymous, internal-only — see Observability §3.1 / §7).
+
+| Check | Type | Endpoint | Interval | Failure threshold | Action |
+|-------|------|----------|----------|-------------------|--------|
+| Docker liveness | HTTP GET (in-container, via `Dockerfile` `HEALTHCHECK`) | `/health/live` | 30 s | 3 consecutive | Docker marks container `unhealthy`; **does NOT auto-restart** in cycle 1 (no `--restart=on-failure` policy in `start-container.sh`) |
+| Nginx readiness | HTTP GET (upstream `health_check`) | `/health/ready` | 5 s | 3 consecutive | Nginx pulls upstream → 503 to clients (no silent traffic loss) |
+| Deploy-script startup | HTTP GET (polling) | `/health/ready` | 2 s | up to 30 attempts (~60 s) | `scripts/deploy.sh` aborts and triggers rollback |
+
+### Health Check Response Contract
+
+| Endpoint | 200 condition | 5xx condition | Headers |
+|----------|---------------|---------------|---------|
+| `/health/live` | Process is responsive (always — short-circuits before any dependency call) | Never returns 5xx unless the process is wedged | `Cache-Control: no-store` |
+| `/health/ready` | `SELECT 1` succeeds against both `AzaionDb` (reader) and `AzaionDbAdmin` (writer) within a 2 s timeout | Either DB query fails or times out → 503 | `Cache-Control: no-store` |
+
+`/health/ready` does NOT exercise the filesystem (`Content/`, `logs/`) — a transient `EACCES` there should not yank the upstream. It surfaces in metrics (`resource_upload_failures_total`) and alerts (Observability §5) instead.
+
+## 3. Staging Deployment
+
+Triggered manually by the operator from the staging host or from a Woodpecker manual workflow.
+
+```
+1. Pre-flight                        — operator on local machine
+   a. Confirm CI green for the target SHA on the `stage` branch.
+   b. Run `dotnet list package --vulnerable` against the target commit (CI does this too — local is a sanity check).
+   c. Confirm any DB migration in env/db/ for this SHA has been reviewed.
+
+2. DB migration (if any)            — operator SSH to staging host
+   psql -h localhost -p 4312 -U azaion_superadmin -d azaion -f env/db/NN_<desc>.sql
+
+3. Deploy                           — operator runs scripts/deploy.sh on staging host
+   ENV=staging ./scripts/deploy.sh <sha-tag>
+   # script: docker pull → stop -t 40 → rm → run --env-file .env → poll /health/ready
+
+4. Verify                           — automatic in scripts/deploy.sh
+   - /health/ready returns 200 within 60 s
+   - Container `docker inspect` healthcheck status is `healthy`
+   - `docker logs --tail=80` contains no `Error` lines from the last 60 s
+
+5. Smoke tests                      — operator runs from local machine
+   BASE_URL=https://stage.admin.azaion.com ./scripts/smoke.sh
+   # 6 critical-path checks: /login (admin), GET /users (paginates), GET /classes,
+   # GET /resources/list, /health/ready, JWT lifecycle.
+
+6. Soak                             — observe dashboard for ≥ 24 h before promoting
+```
+
+If any step fails → §5 Rollback.
+
+## 4. Production Deployment
+
+```
+1. Approval                         — required: ops lead OR backend lead
+   - Reference the staging soak completion timestamp.
+   - Reference the cycle's deploy ticket (AZ-NNN) and CI run URL.
+
+2. Pre-deploy checks (operator on local machine)
+   [ ] Staging smoke tests passed (§3 step 5).
+   [ ] Staging soaked ≥ 24 h with no Critical/High alerts.
+   [ ] CI green for the same SHA on the `main` branch.
+   [ ] Image-scan report for the SHA shows zero High/Critical (Woodpecker artifact).
+   [ ] DB migration plan recorded in the deploy ticket.
+   [ ] Rollback target SHA is recorded (the SHA currently running in prod — `docker inspect azaion.api | jq -r '.[0].Config.Labels."org.opencontainers.image.revision"'`).
+   [ ] On-call engineer is reachable for the next 30 min.
+
+3. DB migration (if any)            — operator SSH to prod host
+   psql -h localhost -p 4312 -U azaion_superadmin -d azaion -f env/db/NN_<desc>.sql
+
+4. Deploy                           — operator runs scripts/deploy.sh on prod host
+   ENV=production ./scripts/deploy.sh <sha-tag>
+
+5. Verify                           — automatic + operator
+   - /health/ready returns 200 within 60 s.
+   - Container `docker inspect` healthcheck status `healthy`.
+   - Operator hits `/login` with admin creds and a known user list query.
+
+6. Monitor                          — operator observes dashboards for ≥ 15 minutes
+   - Error rate (5xx) stays < 1%.
+   - P95 latency stays within 2× cycle-1 baseline (66 ms /login, 305 ms /users).
+   - No Critical or High alerts fire.
+
+7. Finalize
+   - Update deploy ticket with start/stop timestamps and image SHA.
+   - Post `:white_check_mark: prod deploy: <sha-tag>` to Slack #azaion-ops.
+```
+
+## 5. Rollback Procedures
+
+### Trigger Criteria (any one)
+
+- `/health/ready` fails for ≥ 60 s after deploy.
+- Error rate (5xx) > 5 % for 5 minutes within the 15-minute observation window.
+- Any Critical alert fires within 15 minutes of deploy.
+- Operator's manual call (e.g. business-impacting bug surfaced by smoke tests).
+
+### Rollback Steps (≤ 5 minutes)
+
+```
+1. Capture state                    — operator on the affected host
+   docker logs azaion.api --tail=500 > /var/log/azaion/rollback-$(date -u +%Y%m%dT%H%M%SZ).log
+   docker inspect azaion.api > /var/log/azaion/rollback-$(date -u +%Y%m%dT%H%M%SZ).inspect.json
+
+2. Re-deploy previous SHA           — operator
+   ENV=production ./scripts/deploy.sh <previous-sha-tag>
+   # The SHA tag was recorded in step 2 of the deploy procedure.
+
+3. DB rollback (if a migration was applied this deploy)
+   - If reversible (drop column, drop index): run the agreed reverse SQL recorded in the deploy ticket.
+   - If irreversible (added column, table): leave the schema as-is — the previous code is backward-compatible (rule §1.3) so the extra schema is inert.
+   - If data was migrated destructively: STOP, escalate to backend lead. Restore from backup if necessary.
+
+4. Verify                           — same checks as deploy §5
+5. Notify                           — operator posts ":rotating_light: prod rollback: <previous-sha>" to Slack #azaion-ops with the deploy ticket link.
+6. Post-mortem                      — schedule within 24 hours; required artifact: timeline + root cause + prevention.
+```
+
+### Post-Mortem (required)
+
+Template lives in `_docs/06_metrics/postmortem_template.md` (added in Step 7). Required sections:
+
+- Timeline (UTC), with deploy SHA and rollback SHA.
+- Root cause (one sentence + evidence link).
+- Detection — how was it caught? Which alert? Which probe? Which user report?
+- Repair — what fixed it?
+- Prevention — concrete change (test, alert, procedure step) with an owner and a target date.
+
+## 6. Deployment Checklist (per release)
+
+Copy this into the deploy ticket; tick before flipping `prod`:
+
+```
+[ ] CI green on target SHA (01-test + 02-build-push, all matrix entries)
+[ ] Image scan report: zero High/Critical CVEs (Woodpecker artifact)
+[ ] Dependency audit (`dotnet list package --vulnerable`): zero High/Critical
+[ ] Image SHA tag exists in registry: docker manifest inspect $REGISTRY_HOST/azaion/admin:<sha-tag>-arm
+[ ] DB migration (if any) reviewed by backend lead; rollback SQL recorded if reversible
+[ ] secrets/staging.env / secrets/production.env decrypts cleanly on the target host
+[ ] Health endpoints respond 200 in current production (sanity baseline)
+[ ] Monitoring alerts armed (no silenced alerts that would mask the deploy)
+[ ] Rollback target SHA recorded
+[ ] Stakeholders notified (Slack #azaion-ops, expected window)
+[ ] On-call engineer reachable for the next 30 min
+```
+
+## 7. Drifts Logged Here
+
+| ID | Severity | Description | Carried Forward |
+|----|----------|-------------|-----------------|
+| N (NEW) | Medium | No zero-downtime deploy strategy — single-container topology produces ~30 s gap per deploy | Future cycle: blue-green via dual ports + Nginx upstream switch |
+
+## 8. Self-verification
+
+- [x] Deployment strategy chosen (stop-and-start) with explicit rationale and acknowledgement that zero-downtime is deferred (Drift N).
+- [x] Graceful-shutdown contract specified (`HostOptions.ShutdownTimeout` 30 s, `docker stop -t 40`).
+- [x] Health checks defined (liveness, readiness, startup) with exact response contract and Cache-Control header.
+- [x] Rollback trigger criteria + 6-step rollback procedure + post-mortem template requirement.
+- [x] Deployment checklist complete (10 items) and explicitly references the SHA tag (Drift A resolution from Step 3).

+# Azaion Admin API — Environment Strategy
+
+**Date**: 2026-05-13 · **Cycle**: 1 · **Status**: planning artifact (no scripts; concrete wiring lands in Step 7).
+
+## 1. Environments
+
+| Environment | Purpose | Infrastructure | Data Source |
+|-------------|---------|----------------|-------------|
+| **Development** | Local developer workflow on macOS / Linux. | Either bare `dotnet run` against host Postgres (port 4312) **or** the new `docker-compose.yml` planned in Step 2 (API + Postgres on a private Docker network). | Empty database; SQL files under `env/db/` create roles + schema; no fixtures. |
+| **Test (CI)** | Black-box tests in CI and locally via `scripts/run-tests.sh`. | `docker-compose.test.yml` — API + Postgres + e2e-runner on a Docker network. | Functional fixtures from `e2e/db-init/00_run_all.sh` + `99_test_seed.sql`. |
+| **Staging** | Pre-production validation. | Self-hosted Linux server, single Docker host, behind Nginx reverse proxy on `stage.admin.azaion.com`. Mirrors prod topology and Postgres major version. | Anonymized snapshot of production (PII scrubbed by an offline script before import). |
+| **Production** | Live system. | Self-hosted Linux server, single Docker host, behind Nginx reverse proxy on `admin.azaion.com`. | Live data; daily off-host backups. |
+
+> Test is added as a first-class environment because cycle 1 already exercises it (`docker-compose.test.yml`). The deploy template lists three; we list four to match reality.
+
+## 2. Environment Variables
+
+### Source of Truth
+
+The complete variable inventory lives in `.env.example` at the repo root (Step 1, 24 entries). This document does NOT duplicate that table — it only specifies, per environment, **where each variable is sourced**.
+
+### Per-environment sourcing
+
+| Variable group | Development | Test (CI) | Staging | Production |
+|----------------|-------------|-----------|---------|------------|
+| `ASPNETCORE_ENVIRONMENT` | `.env` (`Development`) | docker-compose `environment:` (`Development`) | docker-compose / `--env-file` (`Staging`) | docker-compose / `--env-file` (`Production`) |
+| `ASPNETCORE_URLS` | `.env` | compose | host `.env` (rendered from sops) | host `.env` (rendered from sops) |
+| `ConnectionStrings__*` | `.env` (real local creds) | compose (literal — accepted F-10) | **sops-encrypted file in git** → decrypted on host at deploy time | same as staging |
+| `JwtConfig__Secret` | `.env` (dev-only literal) | compose (literal — accepted F-10) | **sops-encrypted** | **sops-encrypted** |
+| `JwtConfig__{Issuer,Audience,Lifetime}` | appsettings defaults | appsettings defaults | host `.env` if non-default | host `.env` if non-default |
+| `ResourcesConfig__*` | appsettings defaults | compose | host `.env` if non-default | host `.env` if non-default |
+| `DEPLOY_*`, `REGISTRY_TAG` | `.env` (developer machine) | n/a | passed to `scripts/deploy.sh` from operator's shell or CI manual trigger | same |
+| `REGISTRY_USER`, `REGISTRY_TOKEN` | empty in dev `.env` | Woodpecker secrets `registry_user` / `registry_token` | Woodpecker secrets (CI deploy) or operator's shell (manual deploy) | same |
+| `CI_COMMIT_SHA` | unset → image label `unknown` | Woodpecker built-in | Woodpecker built-in | Woodpecker built-in |
+
+### Variable Validation (fail-fast)
+
+The Admin API already does this for the most security-critical variable:
+
+```csharp
+var jwtConfig = builder.Configuration.GetSection(nameof(JwtConfig)).Get<JwtConfig>();
+if (jwtConfig == null || string.IsNullOrEmpty(jwtConfig.Secret))
+    throw new Exception("Missing configuration section: JwtConfig");
+```
+
+The deploy plan **adds** the same fail-fast check for connection strings during Step 7 wiring (a one-time `_ = configuration.GetConnectionString("AzaionDb") ?? throw …` plus the same for `AzaionDbAdmin`, executed during `WebApplication` build). Without the check, a missing variable currently surfaces only on the first DB call, which is too late.
+
+> Static / lookup-style variables (`ResourcesConfig__*`, `JwtConfig__{Issuer,Audience,Lifetime}`) keep their `appsettings.json` defaults in every environment unless an override is required. We do NOT add fail-fast checks for them.
+
+## 3. Secrets Management
+
+### Decision
+
+| Environment | Method | Tool |
+|-------------|--------|------|
+| Development | `.env` file | committed `.env.example` + per-developer `.env` (git-ignored) |
+| Test (CI) | docker-compose `environment:` literals | accepted as test-only (security audit F-10) |
+| Staging | git-tracked encrypted file | **sops + age** |
+| Production | git-tracked encrypted file | **sops + age** |
+
+### Why sops + age (not Vault, not Woodpecker secrets, not hand-edited `.env`)
+
+Constraints: self-hosted, no cloud account, single ops engineer, currently hand-editing `.env` on the host.
+
+| Option | Pros | Cons | Verdict |
+|--------|------|------|---------|
+| sops + age (chosen) | Secrets versioned in git, encrypted at rest, decrypted on the host with a single age key. No new infra. Works offline. | Requires per-environment age keypair stored on the host outside git. Manual key rotation. | ✅ pragmatic for this team size and topology |
+| HashiCorp Vault (self-hosted) | Dynamic DB creds, audit log, fine-grained ACL, KV v2. | Adds a service to operate, monitor, back up. Single-engineer ops budget cannot absorb it now. | ⏳ revisit in a future cycle when ops capacity grows |
+| Woodpecker secrets exported into runtime container | Reuses existing secret store. | Couples runtime config to CI; secrets are not visible/auditable outside Woodpecker UI; cannot run the container outside CI without manually exporting them. | ❌ leaks the CI/runtime boundary |
+| Hand-edited host `.env` (status quo) | Zero new tooling. | No version history, no encryption, no review trail. Single point of failure if the file is lost; security audit can't track changes. | ❌ status quo we are leaving behind (Drift B) |
+
+### sops + age conventions for this repo
+
+```
+secrets/
+├── .sops.yaml                 # routes secrets/staging.env / production.env to the right age recipients
+├── staging.env                # SOPS-encrypted; safe to commit
+└── production.env             # SOPS-encrypted; safe to commit
+```
+
+- `.sops.yaml` declares two age recipients: `recipient_staging` and `recipient_production` (public keys).
+- The matching age **private** keys live on each host at `/etc/azaion/age.key`, mode `0400`, owned by root. They are NEVER committed.
+- `scripts/deploy.sh` (Step 7) runs `SOPS_AGE_KEY_FILE=/etc/azaion/age.key sops -d secrets/${env}.env > /tmp/azaion.env` and feeds it to `docker run --env-file`.
+- All staging/production env values that are NOT secret (e.g. `DEPLOY_HOST_PORT`, `REGISTRY_TAG`) live in plain-text `secrets/staging.public.env` / `secrets/production.public.env` next to the encrypted file, also git-tracked. Loaded before the decrypted overlay.
+
+### Rotation policy
+
+| Secret | Rotation cadence | Procedure |
+|--------|------------------|-----------|
+| Postgres `azaion_admin` / `azaion_reader` passwords | every 90 days, on operator schedule | `ALTER ROLE … WITH PASSWORD …` → re-encrypt `production.env` → `scripts/deploy.sh` |
+| JWT `JwtConfig__Secret` | every 180 days, AND on any suspected leak | re-encrypt → deploy. **All issued tokens become invalid** — communicate maintenance window. |
+| `azaion_superadmin` password | every 365 days, AND on owner change | manual; not used by the running app, only by DB migrations |
+| Registry `REGISTRY_TOKEN` | every 90 days OR on CI compromise | rotate registry credential → update Woodpecker secret `registry_token` → re-encrypt `production.env` if also referenced there |
+| age private key (`/etc/azaion/age.key`) | every 365 days OR on host compromise | generate new key → add public recipient to `.sops.yaml` → `sops updatekeys secrets/*.env` → distribute new private key out-of-band → remove old recipient |
+
+## 4. Database Management
+
+| Environment | Type | Migrations | Data | Backup |
+|-------------|------|------------|------|--------|
+| Development | Local Postgres on host (port 4312) **or** dockerized Postgres from `docker-compose.yml` | `env/db/*.sql` applied manually by developer the first time, then `*_users_email_unique.sql`-style additive scripts run with `psql` on demand | empty | none |
+| Test (CI) | Postgres 16-alpine from `docker-compose.test.yml` | `env/db/*.sql` mounted into `/docker-entrypoint-initdb.d/sql/`, ordered by `00_run_all.sh` | `99_test_seed.sql` (functional) + 500 perf users injected by `scripts/run-performance-tests.sh` when needed | none — `down -v` between runs |
+| Staging | Same Postgres major (16) on the staging server, port 4312, `azaion` database | `env/db/*.sql` applied **manually under change control** via `psql -U azaion_superadmin`. New migrations land in the same numeric-prefix sequence (`07_*.sql`, `08_*.sql`, …) | anonymized prod snapshot, refreshed on demand | nightly `pg_dump` snapshot retained 14 days |
+| Production | Same Postgres 16 on prod server | Same as staging; **migration must be applied to staging first**, observed for ≥ 24 h, then promoted to prod with operator approval | live | nightly `pg_dump` retained 30 days; weekly snapshot retained 12 weeks; off-host copy via `rsync` |
+
+### Migration rules (cycle 1)
+
+The project does NOT use an ORM migration framework (linq2db; restrictions.md). The conventions below replace it:
+
+1. **Numeric-prefix ordering** — every new migration is added as `env/db/NN_<description>.sql` where `NN` continues the existing sequence. The current sequence is `01..06`; the next is `07_*.sql`.
+2. **Forward-only by default**. Reversibility is provided by the off-host backup, NOT by hand-written DOWN scripts. The existing files (`02_structure.sql`, `03_add_timestamp_columns.sql`, `04_detection_classes.sql`, `06_users_email_unique.sql`) follow this pattern; we keep it.
+3. **Backward-compatible deploys** — every schema change must be safe to apply BEFORE the matching code is deployed (additive change → deploy code → cleanup change in a later release). The cycle 1 example: `06_users_email_unique.sql` was applied first; the `RegisterUser` change to translate `23505` came after. AZ-197's `User.Hardware` column was kept as a tombstone instead of dropped, for the same reason.
+4. **Production migrations need approval** — operator manually runs the SQL on prod after staging soak. No automatic CI execution against prod in cycle 1 (Drift J — automation is a future cycle's work).

+# Azaion Admin API — Observability
+
+**Date**: 2026-05-13 · **Cycle**: 1 · **Status**: planning artifact (no code changes; concrete wiring lands in Step 7).
+
+## 1. Current State (audit)
+
+| Pillar | Today | Gap |
+|--------|-------|-----|
+| Logging | Serilog 4.1.0 → Console + rolling file `logs/log.txt` (daily); MinimumLevel `Information`; FromLogContext enrichment | No structured fields beyond defaults; one unstructured `LogInformation($"…")` in `ResourcesService.SaveResource` (security audit F-12); SQL trace bypasses Serilog (`Console.WriteLine`); no correlation IDs |
+| Metrics | none | No `/metrics` endpoint; no system, app, or business metrics |
+| Tracing | none | No OpenTelemetry, no W3C trace context |
+| Health checks | none in code; `docker-compose.test.yml` uses raw TCP probe | No `/health` endpoint (Drift H from Step 2 + skill self-verification) |
+| Alerting | none | No alerts wired to any channel |
+
+This step closes the planning gap; implementation lands incrementally — `/health` and structured logging in cycle 1 (Step 7), metrics + tracing in a later cycle (Drift K).
+
+## 2. Logging
+
+### 2.1 Format
+
+Structured JSON to **stdout/stderr only** in containers. The current rolling-file sink is **dropped from the production runtime** (and the `/app/logs` bind mount becomes optional) because:
+
+- Container logs should be collected by the platform, not the app.
+- A bind-mounted file silently fills the host disk when log rotation lags.
+- We currently have no log shipper, so logs already live only in `docker logs` for ops triage.
+
+The existing console sink stays. The file sink is kept ONLY in `Development` (gated by `ASPNETCORE_ENVIRONMENT`).
+
+```json
+{
+  "timestamp": "2026-05-13T06:48:01.123Z",
+  "level": "Information",
+  "service": "azaion.admin-api",
+  "revision": "a1b2c3d4e5f6",
+  "correlation_id": "0HMU7…",
+  "user_id": null,
+  "message": "User registered",
+  "context": {
+    "endpoint": "POST /users",
+    "duration_ms": 47
+  }
+}
+```
+
+Achieved by adding `Serilog.Formatting.Compact.RenderedCompactJsonFormatter` to the console sink and three enrichers:
+
+| Enricher | Source | Purpose |
+|----------|--------|---------|
+| `FromLogContext` | already present | scoped properties |
+| `Serilog.Enrichers.Environment` (new) | `ENV` vars | `service`, `revision` (`AZAION_REVISION`) |
+| `Serilog.AspNetCore.RequestLoggingOptions` (new) | ASP.NET pipeline | request `correlation_id` from `Activity.Current.TraceId` (or generated UUID v7 if no Activity) |
+
+### 2.2 Log Levels
+
+| Level | Usage | Examples in this codebase |
+|-------|-------|---------------------------|
+| `Error` | Unhandled exceptions, infra failures | DB connection failure, sops decrypt failure on host |
+| `Warning` | Business exception caught | Existing `BusinessExceptionHandler` already does this — keep as-is |
+| `Information` | Significant business events | Login, RegisterUser, RegisterDevice, role change, resource upload, detection-class CRUD |
+| `Debug` | Diagnostic detail | Request/response payloads (dev only — never in production); query parameters |
+
+### 2.3 Retention
+
+| Environment | Destination | Retention |
+|-------------|-------------|-----------|
+| Development | console + `logs/log.txt` (rolling daily) | 7 daily files (Serilog default) |
+| Test (CI) | console (captured by Woodpecker UI) | 14 days (Woodpecker artifact retention) |
+| Staging | container stdout → `journald` on the host | 7 days; `journalctl --vacuum-time=7d` cron |
+| Production | container stdout → `journald` on the host | 30 days; `journalctl --vacuum-time=30d` cron |
+
+> A central log aggregator (Loki / OpenSearch) is **out of scope for cycle 1** — host `journald` is the entire pipeline. Recorded as **Drift L**.
+
+### 2.4 PII Rules
+
+| Rule | Implementation |
+|------|----------------|
+| Never log passwords | `LoginRequest.Password`, `RegisterUserRequest.Password`, `GetResourceRequest.Password`, the response body of `POST /devices` (plaintext one-shot password). Add a `[Serilog.Sensitive]`-style helper or a `Destructure.ByTransforming<T>(t => …)` per DTO. |
+| Never log JWT tokens | The `/login` response body is logged today only by `BusinessExceptionHandler` on failure, which doesn't include the body. Verify in Step 7 that no request-logger middleware logs response bodies. |
+| Mask emails | Use last-4 + `@domain` form for INFO-level logs (`***123@example.com`); full email allowed at DEBUG only. The `BusinessExceptionHandler` log line `"Caught BusinessException: {Message}"` may include emails embedded in messages — tightened in Step 7. |
+| User IDs | `User.Id` is an opaque GUID — safe to log; use it instead of email in correlation. |
+
+## 3. Metrics
+
+### 3.1 Endpoint
+
+`GET /metrics` exposing Prometheus exposition format. Add via `prometheus-net.AspNetCore` 8.x (latest stable for .NET 10 baseline; verify version against released wheel before wiring).
+
+> Exposure boundary: `/metrics` MUST NOT be reachable from the public CORS allow-list. The Nginx reverse proxy on `admin.azaion.com` will expose only `/login`, `/users*`, `/devices`, `/resources*`, `/classes*`, `/health`. `/metrics` and `/swagger` stay on the internal interface (separate Nginx server block bound to the management VLAN, OR `localhost`-only listener).
+
+### 3.2 Metrics
+
+| Metric | Type | Source | Labels |
+|--------|------|--------|--------|
+| `http_requests_total` | Counter | ASP.NET request pipeline | `method`, `endpoint`, `status_code` |
+| `http_request_duration_seconds` | Histogram | ASP.NET request pipeline | `method`, `endpoint` |
+| `http_requests_in_progress` | Gauge | ASP.NET request pipeline | `method` |
+| `db_command_duration_seconds` | Histogram | linq2db trace hook | `operation` (`select`/`insert`/`update`/`delete`) |
+| `db_command_failures_total` | Counter | linq2db trace hook | `operation`, `sqlstate` |
+| `auth_login_failures_total` | Counter | `AuthService.ValidateUser` exception path | `reason` (`unknown_user`, `bad_password`, `disabled`) |
+| `business_exceptions_total` | Counter | `BusinessExceptionHandler` | `error_code` (the existing `ExceptionEnum`) |
+| `resource_upload_bytes_total` | Counter | `ResourcesService.SaveResource` | `data_folder` |
+| `resource_upload_failures_total` | Counter | same | `reason` |
+| `resource_download_bytes_total` | Counter | `ResourcesService.GetEncryptedResource` | `data_folder` |
+| `detection_classes_total` | Gauge | refresh on CRUD | none |
+| `users_active_total` | Gauge | refresh on CRUD + on a 5-min timer | `role` |
+| Process / runtime | (auto) | `prometheus-net.DotNetRuntime` | gen0/1/2 GC, JIT, threadpool, etc. |
+
+### 3.3 System Metrics
+
+CPU, RSS, file descriptors, network I/O — collected by **node-exporter** running on the host as a sibling container. The Admin API itself does NOT export host-level metrics.
+
+### 3.4 Business Metrics
+
+Mapped to the verified ACs in `_docs/02_document/tests/blackbox-tests.md`. Cycle-1 cut: `users_active_total` (AC-01..AC-12 user lifecycle) and `detection_classes_total` (AZ-513). Resource-related business metrics deferred until the resource flow is exercised by real users post-AZ-197.
+
+### 3.5 Collection
+
+| Setting | Value |
+|---------|-------|
+| Scrape interval | 15s (Prometheus default) |
+| Scrape source | `node-exporter` for host; the Admin API container for app metrics |
+| Storage | local Prometheus on the host, retention 14 days (cycle 1 budget) |
+| Visualization | local Grafana, single dashboard (§6) |
+
+## 4. Distributed Tracing
+
+**Cycle 1**: scaffold only — produce a trace ID per request, propagate via `traceparent` (W3C), and emit it as the `correlation_id` field in JSON logs. **Do NOT yet** ship spans to a collector — there is no Jaeger / Tempo running, and the Admin API has no downstream services to trace into. Tracing pays back its cost when there's a chain to follow; cycle 1 has none.
+
+| Setting | Value |
+|---------|-------|
+| SDK | `OpenTelemetry.Extensions.Hosting` + `OpenTelemetry.Instrumentation.AspNetCore` |
+| Propagation | W3C Trace Context (`traceparent`) — auto when `OpenTelemetry.Instrumentation.AspNetCore` is registered |
+| Sampling | 100% in dev/staging, 10% in production (deferred — no exporter yet) |
+| Span naming | `<service>.<operation>` — service `azaion.admin-api`, operation `<HTTP method> <route template>` |
+| Exporter | none in cycle 1 (logs only) |
+
+> Recorded as **Drift M** — wire a Tempo / Jaeger exporter once a downstream service exists.
+
+## 5. Alerting
+
+| Severity | Response time | Conditions for this service | Channel |
+|----------|---------------|------------------------------|---------|
+| Critical | 5 min | `up{job="admin-api"} == 0` for 1 min · `/health` fails for 2 min · `business_exceptions_total{error_code="DbFailure"}` rate > 1/s for 1 min | Slack `#azaion-ops` + on-call email (cycle 1 — PagerDuty deferred until on-call rotation exists) |
+| High | 30 min | Error rate > 5% for 5 min (`http_requests_total{status_code=~"5.."}/total`) · P95 latency > 2× baseline for 10 min · `auth_login_failures_total` rate > 10/s for 1 min (possible brute force) | Slack `#azaion-ops` + email |
+| Medium | 4 h | Host disk > 80% · `db_command_failures_total` rate > 0.1/s for 10 min · process RSS > 80% of container limit | Slack `#azaion-ops` |
+| Low | Next business day | Deprecated package usage from `dotnet list package --deprecated` | Slack `#azaion-eng` |
+
+Baseline values (P95) come from the cycle-1 perf report:
+- `/login` p95 ≈ 33 ms → high-latency alert at p95 > 66 ms for 10 min
+- `/users` (500 users) p95 ≈ 152 ms → high-latency alert at p95 > 305 ms for 10 min
+
+Alert routing in cycle 1 is **inform-only** — no PagerDuty escalation, no auto-rollback. The deploy procedure (Step 6) documents the manual rollback path.
+
+## 6. Dashboards
+
+**Operations dashboard** (Grafana, single panel set; cycle 1):
+
+- Service `up` (admin-api, postgres, nginx) — stat panel
+- HTTP request rate (req/s) by endpoint — time series
+- HTTP error rate (% of 5xx) — time series with the High threshold band overlaid
+- Latency P50 / P95 / P99 by endpoint — time series, P95 baseline reference line
+- DB command rate + failure rate — time series
+- Container CPU / RSS / FDs — time series (from node-exporter)
+- Active alerts — table panel
+
+**Business dashboard** (cycle 1):
+
+- `users_active_total` by role — stat panel + sparkline
+- `detection_classes_total` — stat panel
+- `resource_upload_bytes_total` rate (1h window) — time series
+- Login success/failure ratio (24h) — donut
+
+Dashboards stored as code in `monitoring/grafana/admin-api.json` (introduced in Step 7).
+
+## 7. Health Checks
+
+Add a `/health` Minimal API endpoint:
+
+| Probe | Endpoint | What it checks | Surface |
+|-------|----------|----------------|---------|
+| Liveness | `GET /health/live` | Process is responsive (always 200 unless the process is wedged) | Used by Docker `HEALTHCHECK` |
+| Readiness | `GET /health/ready` | DB reader connection + DB admin connection (one-shot `SELECT 1` each, 2s timeout) | Used by Nginx upstream check + the deploy script (Step 6) post-deploy gate |
+
+Endpoints are anonymous (no JWT) but bound only to the management VLAN (or `localhost` listener) — same exposure rule as `/metrics`.
+
+> Failure mode: if the DB is unreachable for 30 s, `/health/ready` returns 503; Nginx pulls the upstream, returning 503 to clients (no silent traffic loss). The container itself stays running so a transient DB blip does not trigger Docker restart.
+
+## 8. Drifts Logged Here
+
+| ID | Severity | Description | Resolved In |
+|----|----------|-------------|-------------|
+| H  | Low | `docker-compose.test.yml` health check is TCP-only; upgrade to `/health/live` once available | Step 7 |
+| K  | Medium (NEW) | Metrics + tracing not implemented in cycle 1; only the plan + `/health` ship | Future cycle |
+| L  | Low (NEW) | No central log aggregator; `journald` only | Future cycle |
+| M  | Low (NEW) | Tracing has no exporter (cycle 1 = trace IDs in logs only) | Future cycle when downstream services exist |
+
+## 9. Self-verification
+
+- [x] Structured JSON logging format defined with `timestamp`, `level`, `service`, `correlation_id`, `message`, `context`.
+- [x] Metrics endpoint specified (`/metrics`, internal-only) with full app/system/business metric inventory.
+- [x] OpenTelemetry tracing configured at the SDK level (cycle 1) with future exporter wiring (Drift M).

+# Azaion Admin API — Deployment Status Report
+
+**Date**: 2026-05-13
+**Cycle**: 1
+**Step**: Deploy / 1 — Status & Environment Setup
+**Verdict**: **READY for planning** — no critical blockers; three medium drift items must be resolved before Steps 2–7 produce final artifacts.
+
+## Deployment Readiness Summary
+
+| Aspect | Status | Notes |
+|--------|--------|-------|
+| Architecture defined | ✅ | `_docs/02_document/architecture.md` (§3 Deployment Model) |
+| Component specs complete | ✅ | 5 components in `_docs/02_document/components/` |
+| Infrastructure prerequisites met | ⚠️ Partial | Self-hosted Linux + private registry assumed; SSL/DNS not codified |
+| External dependencies identified | ✅ | PostgreSQL (4312) + filesystem; no message bus, no CDN consumed by API |
+| Cycle-1 changes integrated | ✅ | AZ-513 (`/classes`), AZ-196 (`/devices`), AZ-197 (HW removed); AZ-183 (OTA) reverted |
+| Security audit signed off | ⚠️ PASS_WITH_WARNINGS | F-2 deferred to AZ-516; F-6 (root container) carried into Step 2 (containerization) |
+| Performance test signed off | ✅ | NFT-PERF-01/04 PASS; NFT-PERF-02/03 obsolete (OTA reverted) |
+| Blockers | 0 | 3 medium-priority drift items, listed below |
+
+## Component Status
+
+| Component | State | Docker-ready | Notes |
+|-----------|-------|--------------|-------|
+| 01 Data Layer | implemented + tested | n/a (library) | linq2db 5.4.1; entities `User`, `UserConfig`, `RoleEnum`, `DetectionClass`, `ExceptionEnum` |
+| 02 User Management | implemented + tested | n/a (library) | `UserService`, `RegisterUser`/`RegisterDevice` consolidated post-F-3 |
+| 03 Auth & Security | implemented + tested | n/a (library) | JWT bearer + per-user resource encryption (HW component removed AZ-197) |
+| 04 Resource Management | implemented + tested | n/a (library) | Filesystem-backed; OTA paths deleted post-revert |
+| 05 Admin API | implemented + tested | yes | Single deployable container (`Azaion.AdminApi`); composes the four libraries |
+
+> Only the Admin API ships as a runtime container. Libraries are linked into the API at build time.
+
+## External Dependencies
+
+| Dependency | Type | Required For | Status |
+|------------|------|--------------|--------|
+| PostgreSQL 14+ (custom port 4312) | Database | All persistence | needs setup per env (`env/db/`) |
+| Server filesystem (`Content/`, `logs/`) | Local I/O | Resource storage + Serilog rolling files | provisioned by host (bind mounts) |
+| Docker Engine | Runtime | Container execution | required on `DEPLOY_HOST` |
+| Nginx (reverse proxy) | TLS / routing | HTTPS termination, Host header | provisioned by `env/api/02-nginx-docker-registry.sh` |
+
+API has no outbound calls to external SaaS APIs (no SSRF surface).
+
+## Infrastructure Prerequisites
+
+| Prerequisite | Status | Action Needed |
+|--------------|--------|---------------|
+| Container registry | ⚠️ Two registries in flight | Drift A (below): consolidate `docker.azaion.com/api` ↔ `$REGISTRY_HOST/azaion/admin:branch-arm` |
+| Cloud account | n/a | Self-hosted Linux server; no cloud account required |
+| DNS configuration | ✅ | `admin.azaion.com` already in CORS allow-list |
+| SSL certificates | ⚠️ Assumed at proxy | HTTPS not enforced in code (security audit F-13); document upstream chain in Step 6 |
+| CI/CD platform | ✅ | Woodpecker CI on ARM64 (`.woodpecker/01-test.yml`, `02-build-push.yml`) |
+| Secret manager | ❌ Not chosen | Drift B (below): Woodpecker secrets are used in CI; no manager for runtime container `.env` |
+| Container user | ⚠️ root | Drift C: security audit F-6 — add `USER app` in Step 2 (containerization) |
+| Health check endpoint | ❌ Missing | Step 5 (observability) — required for orchestration / load-balancer probes |
+
+## Deployment Drift / Blockers (planning inputs)
+
+| ID | Severity | Description | Resolved In |
+|----|----------|-------------|-------------|
+| Drift A | Medium | Image path in `deploy.cmd` / `env/api/start-container.sh` (`docker.azaion.com/api`) ≠ image path in `.woodpecker/02-build-push.yml` (`$REGISTRY_HOST/azaion/admin:branch-arm`). The host pulls `:latest`, the CI never pushes `:latest`. | Step 3 (CI/CD) + Step 7 (scripts) |
+| Drift B | Medium | Production `.env` is hand-edited on the server. No secret manager, no rotation policy. | Step 4 (env strategy) — propose Vault / sops / SSM |
+| Drift C | Medium | `Dockerfile` final stage runs as root (security audit F-6, AZ-518). | Step 2 (containerization) — add non-root `USER app` (UID 1654) |
+| Drift D | Low | `.woodpecker/build-arm.yml` referenced in old docs but the actual files are `01-test.yml` + `02-build-push.yml`. | Step 3 (CI/CD) — refresh the doc |
+| Drift E | Low | Performance script is run-on-demand (`scripts/run-performance-tests.sh`), not gated in CI. | Step 3 (CI/CD) — optional perf gate |
+| Drift F | Low | No vulnerable-dep gate in CI (security audit recommendation 13). | Step 3 (CI/CD) — `dotnet list package --vulnerable` |
+
+> No **critical** blockers. The drifts are planning inputs for Steps 2–7; they do NOT block Step 1 from completing.
+
+## Required Environment Variables
+
+| Variable | Purpose | Required In | Default (Dev) | Source (Staging/Prod) |
+|----------|---------|-------------|---------------|----------------------|
+| `ASPNETCORE_ENVIRONMENT` | Selects appsettings overlay + Swagger gate | All | `Development` | Environment (`Production`) |
+| `ASPNETCORE_URLS` | Kestrel bind address | Container | `http://+:8080` | Environment |

+| `ASPNETCORE_JwtConfig__Secret` | HMAC-SHA256 signing key (≥ 32 bytes) | All | dev-only literal in `.env` | Secret manager |
+| `ASPNETCORE_JwtConfig__Issuer` | JWT `iss` claim | All | `AzaionApi` (appsettings) | appsettings or env override |
+| `ASPNETCORE_JwtConfig__Audience` | JWT `aud` claim | All | `Annotators/OrangePi/Admins` (appsettings) | appsettings or env override |
+| `ASPNETCORE_JwtConfig__TokenLifetimeHours` | Token TTL | All | `4` (appsettings) | Environment |
+| `ASPNETCORE_ResourcesConfig__ResourcesFolder` | File storage root | All | `Content` | Environment |
+| `ASPNETCORE_ResourcesConfig__SuiteInstallerFolder` | Prod installer dir | All | `suite` | Environment |
+| `ASPNETCORE_ResourcesConfig__SuiteStageInstallerFolder` | Stage installer dir | All | `suite-stage` | Environment |
+| `CI_COMMIT_SHA` | Build-time label → `AZAION_REVISION` env in container | Build only | (unset → `unknown`) | Woodpecker `$CI_COMMIT_SHA` |
+| `DEPLOY_HOST` | Remote target machine for `scripts/deploy.sh` | Deploy scripts | `admin.azaion.com` | Environment |
+| `DEPLOY_SSH_USER` | SSH user on `DEPLOY_HOST` | Deploy scripts | `root` | Environment |
+| `DEPLOY_CONTAINER_NAME` | Docker container name on host | Deploy scripts | `azaion.api` | Environment |
+| `DEPLOY_HOST_PORT` | Published host port (mapped to container 8080) | Deploy scripts | `4000` | Environment |
+| `DEPLOY_HOST_CONTENT_DIR` | Host bind mount for `Content/` | Deploy scripts | `/root/api/content` | Environment |
+| `DEPLOY_HOST_LOGS_DIR` | Host bind mount for `logs/` | Deploy scripts | `/root/api/logs` | Environment |
+| `REGISTRY_HOST` | Container registry hostname | CI + deploy scripts | `docker.azaion.com` | Environment / Woodpecker secret |
+| `REGISTRY_IMAGE` | Image path inside registry | CI + deploy scripts | `azaion/admin` | Environment |

+| `REGISTRY_TOKEN` | Registry login token/password | CI + deploy scripts | (empty) | Woodpecker secret `registry_token` / Secret manager |
+
+> All `ASPNETCORE_…` variables map to ASP.NET Core's `IConfiguration` via the standard `__` separator (e.g., `JwtConfig:Secret` ← `ASPNETCORE_JwtConfig__Secret`). The `ASPNETCORE_` prefix is *required* — `ConfigurationBuilder` only picks up env vars under that prefix unless additional prefixes are wired explicitly (which this app does not do).
+
+## .env Files Created
+
+- `.env.example` — committed to VCS, contains all variable names with placeholder values and inline comments.
+- `.env` — git-ignored (via existing `.gitignore` line `.env`), contains development defaults pointing at the local Postgres on port 4312 and a clearly-marked dev-only JWT secret.
+
+## Acceptance Checklist (Step 1 self-verification)
+
+- [x] All five components assessed for deployment readiness.
+- [x] External dependencies catalogued (Postgres + filesystem only).
+- [x] Infrastructure prerequisites identified, including 6 named drifts (A–F).
+- [x] All required environment variables discovered (24 entries).
+- [x] `.env.example` created with placeholders + comments.
+- [x] `.env` created with safe local defaults (no real secrets).
+- [x] `.gitignore` already excludes `.env` (line 10).
+- [x] Status report written to `_docs/04_deploy/reports/deploy_status_report.md`.
+
+## Next Steps
+
+1. **User confirms** this report (BLOCKING gate at end of Step 1).
+2. Step 2 (Containerization): consume Drift C (non-root `USER`) and the existing multi-stage Dockerfile as the baseline.
+3. Step 3 (CI/CD): consume Drifts A, D, E, F and refresh the documented pipeline against the actual `01-test.yml` / `02-build-push.yml` files.
+4. Step 4 (Environment Strategy): consume Drift B by proposing a secret manager option (e.g., HashiCorp Vault, sops-encrypted files in git, or Woodpecker secrets exported into the runtime container).
+5. Steps 5–7 then layer observability, procedures, and scripts on top.

+
+| Project | Package | Version | Reason | Recommended |
+|---------|---------|---------|--------|-------------|
+| `Azaion.AdminApi` | `FluentValidation.AspNetCore` | 11.3.0 | Legacy (deprecated by maintainer) | Move validators to manual `ServiceCollectionExtensions.AddValidatorsFromAssembly(...)` registration; `FluentValidation` 11.10.0 (already in use elsewhere) is the supported core. The AspNetCore auto-DI helper is no longer maintained. |
+| `Azaion.Services` | `System.IdentityModel.Tokens.Jwt` | 7.1.2 | Legacy (Microsoft pushes consumers to `Microsoft.IdentityModel.JsonWebTokens`) | Migrate to `Microsoft.IdentityModel.JsonWebTokens` (the modern token-handler stack already shipped via `Microsoft.AspNetCore.Authentication.JwtBearer 10.0.3`). |
+| `Azaion.Test` | `xunit` | 2.9.2 | Legacy (`xunit.v3` is the new line) | Plan a migration to `xunit.v3` once it leaves prerelease. Not urgent — `xunit 2.x` still receives security backports. |
+
+Deprecated ≠ vulnerable. None of the three packages above carry an open CVE. They are flagged so we have a paper trail before they reach end-of-life.
+
+## Manual Advisory Cross-Reference
+
+The pinned top-level package list (output of `dotnet list package`) was cross-checked against GitHub Security Advisories for known issues NOT yet surfaced by NuGet metadata:
+
+| Package | Pinned | Advisory | Severity | Fix Version | Notes |
+|---------|--------|----------|----------|-------------|-------|
+| `Newtonsoft.Json` | **13.0.1** | GHSA-5crp-9r3c-p9vr (Improper Handling of Exceptional Conditions — DoS via deeply nested JSON) | **High** | **13.0.2 or higher** | Used transitively + directly across `Azaion.Common`, `Azaion.Services`. Untrusted JSON enters via `LoginRequest`, `RegisterUserRequest`, `GetUpdateRequest`, etc. — all of which deserialize via the ASP.NET Core minimal API stack. Even though minimal API uses `System.Text.Json` by default, the `Newtonsoft.Json` reference is reachable from logging payload formatting and from `ResourceColumnEncryption`-adjacent code paths. **Bump to 13.0.3 or later.** |
+| `LazyCache.AspNetCore` | 2.4.0 | none open | — | — | Last release 2022; in maintenance mode. No advisory. |
+| `Microsoft.AspNetCore.Authentication.JwtBearer` | 10.0.3 | none open | — | — | Latest .NET 10 line. |
+| `Npgsql` | 10.0.1 | none open | — | — | Current. |
+| `linq2db` | 5.4.1 | none open | — | — | Current. |
+| `Swashbuckle.AspNetCore` | 10.1.4 | none open | — | — | Current. |
+| `Serilog` family (`4.1.0` / sinks `6.0.0` / `8.0.0`) | varies | none open | — | — | Current. |
+| `FluentAssertions` | 6.12.2 | n/a (test-only) | — | — | License changed in 8.0; staying on 6.x is fine. |
+
+## Findings
+
+### D-1: `Newtonsoft.Json 13.0.1` is below the patched line for GHSA-5crp-9r3c-p9vr (High) — **RESOLVED in cycle 1**
+
+- **Severity**: High (now closed)
+- **CVE/Advisory**: GHSA-5crp-9r3c-p9vr (DoS via uncontrolled recursion when deserializing deeply nested JSON)
+- **Location at time of finding**: top-level reference in `Azaion.Common.csproj`, `Azaion.Services.csproj`
+- **Resolution (2026-05-13)**: bumped to **13.0.4** (current stable, released 2025-09-17) in both csproj files. `dotnet restore` + `dotnet build` succeeded. Full test suite re-ran clean: 48 e2e (Docker) + 2 unit. The 13.0.1 → 13.0.4 jump is patch-level on the same major; `JsonConvert.SerializeObject` / `DeserializeObject` API surface unchanged at the call sites (`AzaionDbSchemaHolder`, `BusinessExceptionHandler`, `SecurityTest`).
+- **Notes**: NuGet's `--vulnerable` did not flag this on the configured feeds — likely because the GHSA → NuGet vulnerability index sync depends on advisory enrichment that hasn't propagated to all mirrors. Manual upgrade was warranted.

+# Infrastructure & Configuration Review
+
+**Date**: 2026-05-13
+**Scope**: `Dockerfile`, `docker.test/Dockerfile`, `e2e/Dockerfile`, `docker-compose.test.yml`, `appsettings*.json`, `env/db/*.sql`, `.gitignore`, `.dockerignore`. No CI/CD pipeline files (`.github/workflows/`, `.gitlab-ci.yml`, `azure-pipelines.yml`) are present in this workspace.
+
+## Container Security
+
+### Production image (`Dockerfile`)
+
+| Check | Result | Notes |
+|-------|--------|-------|
+| Non-root user | **FAIL** | No `USER` directive — runs as root. See F-6. |
+| Minimal base image | PASS | `mcr.microsoft.com/dotnet/aspnet:10.0` (runtime-only) for the final stage; SDK image used only for build. |
+| Multi-stage build | PASS | Build / publish / runtime stages cleanly separated. |
+| No secrets in build args | PASS | Only `CI_COMMIT_SHA` (passed as `AZAION_REVISION` env at runtime) — non-sensitive. |
+| Health check defined | PASS (compose layer) | `docker-compose.test.yml:42-51` defines a TCP health check; the production deployment must define an equivalent. **Not verified in this audit** because no production compose file exists in this workspace. |
+| Image pinned by digest | **WARN** | Base images use `:10.0` tag, not `@sha256:...` digest. Tag floats — a poisoned upstream tag would be picked up on the next rebuild. Acceptable if the build runs from a controlled cache; otherwise pin. |
+| `EXPOSE` matches Kestrel binding | PASS | `EXPOSE 8080`, `ASPNETCORE_URLS=http://+:8080`. |
+
+### Test sidecar image (`docker.test/Dockerfile`)
+
+```
+FROM alpine:latest
+CMD echo hello
+```
+
+This image is essentially a no-op stub. It's referenced from somewhere in the test/CI tooling but contributes nothing functional. **Recommendation**: either remove it (if nothing references it) or document its purpose. From a security standpoint it's inert — `alpine:latest` is fine for an `echo` and the floating tag is irrelevant for a stub. Flag as **operational hygiene, not a security finding**.
+
+### E2E runner image (`e2e/Dockerfile`)
+
+| Check | Result | Notes |
+|-------|--------|-------|
+| Non-root | **FAIL** (test-only) | Same root-by-default behavior. Test runner only — no exposed network, runs in an ephemeral container per CI run. **Acceptable.** |
+| Uses SDK image as final | **WARN** (test-only) | Final stage is `mcr.microsoft.com/dotnet/sdk:10.0` — needed for `dotnet test`. SDK images carry more attack surface than runtime images, but this container is only reachable on the internal `e2e-net` bridge. **Acceptable for test-only.** |
+
+## docker-compose.test.yml
+
+| Check | Result | Notes |
+|-------|--------|-------|
+| Secrets via env vars (not committed prod secrets) | PASS (test-only) | The DB password, JWT secret, and master key are committed because this is the e2e harness only. F-10 captures the rule: these literals must never appear in a production compose file. |
+| No port leaks | PASS | Only `8080:8080` is published from `system-under-test`; `test-db` is internal to the bridge. |
+| Healthcheck for the API | PASS | TCP probe on `127.0.0.1:8080`. |
+| Network isolation | PASS | All three services share `e2e-net` only; no `host` network mode. |
+| Image lock | **WARN** (test-only) | `postgres:16-alpine` floats. For test reproducibility consider pinning a digest, but not security-critical for an ephemeral test stack. |
+
+There is **no production `docker-compose.yml`** in this workspace. Any production deployment must:
+- Inject `JwtConfig__Secret` and both `ConnectionStrings__*` values from a secret manager (Vault, AWS Secrets Manager, Azure Key Vault). (`ResourcesConfig__EncryptionMasterKey` was the third item here pre-revert; that field has since been deleted along with the OTA feature.)
+- NOT carry over the `ASPNETCORE_ENVIRONMENT=Development` value used in the test compose — that environment value enables Swagger at the root path.
+
+## Environment Configuration
+
+### `Azaion.AdminApi/appsettings.json`
+
+| Field | Value committed | Risk |
+|-------|----------------|------|
+| `Logging.LogLevel.*` | `Information` / `Warning` | OK |
+| `AllowedHosts` | `"*"` | OK at the framework level — host filtering is normally enforced upstream by the reverse proxy. |
+| `ResourcesConfig.ResourcesFolder` | `"Content"` | Relative path; resolves under the working directory inside the container. OK. |
+| ~~`ResourcesConfig.EncryptionMasterKey`~~ | — | **Removed in the post-cycle-1 revert** along with the OTA feature; field no longer exists in `ResourcesConfig`, `appsettings.json`, or `docker-compose.test.yml`. Closes F-5 automatically. |
+| `JwtConfig.{Issuer, Audience, TokenLifetimeHours}` | committed | Public-by-design (not secrets). |
+| `JwtConfig.Secret` | **NOT committed** | Correct. Supplied via env var. |
+| `ConnectionStrings.*` | **NOT committed** | Correct. Supplied via env var. |
+
+### `Azaion.AdminApi/appsettings.Development.json`
+
+Empty except for log levels — fine.
+
+### `e2e/Azaion.E2E/appsettings.test.json`
+
+Test-only. F-10 captures this; not a production concern.
+
+## Secrets Hygiene
+
+| Pattern | Where | Disposition |
+|---------|-------|-------------|
+| Plaintext DB passwords | `env/db/01_permissions.sql` | F-11 — operator template, not runtime. Add a header comment. |
+| Plaintext DB / JWT / master-key in `docker-compose.test.yml` | `docker-compose.test.yml:31-37` | F-10 — test-only. CI guard recommended. |
+| Plaintext admin/uploader passwords in `e2e/Azaion.E2E/appsettings.test.json` | as above | F-10 — test-only. |
+| `.env` ignored | `.gitignore:10` | PASS |
+| `bin/`, `obj/`, `logs/`, `Content/` ignored | `.gitignore:2-3, 7, 9` | PASS — keeps build artifacts and runtime data out of git. |
+
+## CI/CD
+
+No CI configuration files were found in the workspace (`.github/workflows/`, `.gitlab-ci.yml`, `azure-pipelines.yml`, `Jenkinsfile` — none present). Either:
+- CI is configured outside this repo (e.g., upstream meta-repo), in which case the security guardrails (`dotnet list package --vulnerable`, secret-scanning, dependency-review) need to be verified there.
+- Or there is no automated CI today, in which case this is a meta-finding: the dependency-bump (D-1) and the test suite have no automated gate. **Recommend**: introduce at least a `dotnet build && dotnet test && dotnet list package --vulnerable` job before deploy.
+
+## Network Security
+
+| Check | Status | Notes |
+|-------|--------|-------|
+| HTTPS enforcement in code | **FAIL** | F-13 — assumed at reverse proxy. |
+| HSTS | not configured | Acceptable if reverse proxy injects it. |
+| CORS | tight | `AdminCorsPolicy` whitelist-only (`https://admin.azaion.com`, `http://admin.azaion.com`). The plaintext `http://` origin can be removed once the SaaS UI is HTTPS-only. |
+| Security headers | not configured in app | `X-Frame-Options`, `X-Content-Type-Options`, `Content-Security-Policy` not set in code. Reverse proxy responsibility today; document the assumption. |
+

+# OWASP Top 10 Review (2021 edition)
+
+**Date**: 2026-05-13
+**Framework**: [OWASP Top 10 — 2021](https://owasp.org/www-project-top-ten/) (the 2025 release is not yet finalized as of this audit; 2021 remains the current authoritative list).
+**Scope cross-reference**: every FAIL below cites a Phase 2 finding ID (`F-N`) for the underlying evidence.
+
+## Per-Category Assessment
+
+| # | Category | Status | Findings |
+|---|----------|--------|----------|
+| A01 | Broken Access Control | **FAIL** | F-2 (path traversal via `dataFolder`) — F-1 closed via OTA feature revert |
+| A02 | Cryptographic Failures | PASS_WITH_WARNINGS | F-1 closed via revert; D-1 closed via Newtonsoft bump (13.0.4); F-7 (SHA-384 password hash, no salt/KDF) remains open as a hardening item |
+| A03 | Injection | **PASS** | linq2db parameterizes all queries; no string-concatenation SQL paths found in `Azaion.Services/*Service.cs` or `Azaion.Common/Database/*`. No `Process.Start` / `subprocess` usage in production code. No template injection paths. |
+| A04 | Insecure Design | PASS_WITH_WARNINGS | F-3 closed (UNIQUE INDEX `users_email_uidx` + `RegisterUser`/`RegisterDevice` consolidation); F-8 (no rate limiting on `/login`) remains as a hardening item |
+| A05 | Security Misconfiguration | **FAIL** | F-6 (container runs as root), F-13 (no HTTPS enforcement in code), F-9 (request DTOs missing validators), F-11 (placeholder credentials in `01_permissions.sql`). F-5 closed automatically (`EncryptionMasterKey` field deleted with the OTA revert). |
+| A06 | Vulnerable & Outdated Components | **PASS** | All `dotnet list package --vulnerable` checks return clean. D-1 (Newtonsoft.Json) was the only manual finding; closed in this audit by bumping to 13.0.4. Three deprecated-but-not-vulnerable packages noted in `dependency_scan.md`. |
+| A07 | Identification & Authentication Failures | PASS_WITH_WARNINGS | F-3 closed (DB UNIQUE INDEX now enforces one-row-per-email). F-7 (weak password hashing) and F-8 (no rate limiting) remain open as hardening items. |
+| A08 | Software & Data Integrity Failures | **PASS** | OTA flow that introduced the unsigned-manifest concern was reverted. CI/CD: secrets are env-injected, no in-repo secrets in `Dockerfile` / compose files used by prod. |
+| A09 | Security Logging & Monitoring Failures | **PASS_WITH_WARNINGS** | Serilog console + rolling file sink configured. F-12 (one unstructured log line in `ResourcesService`). No security-event-specific logger — login successes/failures, role changes, deletes are not separately auditable. |
+| A10 | Server-Side Request Forgery (SSRF) | **NOT_APPLICABLE** | The API never makes outbound HTTP calls based on user-controlled URLs. `CdnUrl` from `PublishResourceRequest` is stored and forwarded but never fetched server-side. |
+
+## Cross-Reference Against `security_approach.md`
+
+The pre-cycle-1 `security_approach.md` "Known Security Observations" list is reconciled here:
+
+| Original observation | Status post-cycle-1 |
+|----------------------|---------------------|
+| 1. SHA-384 without per-user salt | **Still open** — F-7 |
+| 2. `hardware_hash` DB column unused | **Resolved by AZ-197** — column-level removal pending follow-up; field is now dead but the column is still in the schema (`02_structure.sql:9`). Not a security risk; cleanup task. |
+| 3. No path traversal protection on `dataFolder` | **Still open** — F-2 |
+| 4. Hardcoded DB credentials in test files | **Confirmed test-only** — F-10 |
+| 5. No rate limiting on `/login` | **Still open** — F-8 |
+| 6. No audit trail for security-relevant operations | **Still open** — A09 PASS_WITH_WARNINGS |
+| 7. No HTTPS enforcement in code | **Still open** — F-13 |
+| 8. Static encryption key salts hardcoded | **Partially resolved** — `Security.GetApiEncryptionKey` salt is still hardcoded but the AZ-197 removal of the `hwHash` component reduced surface area. (`ResourceColumnEncryption` was deleted along with the OTA revert.) |
+
+## Cycle-1 Specific Verdict
+
+The cycle-1 changes (AZ-513, AZ-196, AZ-183, AZ-197) introduced one new High-severity finding (F-1, on `/get-update`) and amplified one existing High (F-3, via `RegisterDevice`). Both were closed before any deploy:
+
+- **F-1 (resolved by feature revert)**: AZ-183 was reverted in full; the OTA delivery model itself is obsolete in the target architecture.
+- **F-3 (resolved)**: `RegisterDevice` now delegates to `RegisterUser`; `users.email` has a UNIQUE INDEX (`users_email_uidx`); UNIQUE-violation is translated to `EmailExists`.
+
+Other cycle-1 endpoints (`/devices`, `/classes/*`) have correct authorization wiring (`apiAdminPolicy`).
+
+## Self-verification
+
+- [x] All current OWASP Top 10 categories assessed
+- [x] Each FAIL has at least one specific finding with evidence (F-N reference)
+- [x] NOT_APPLICABLE category has justification (A10)

+# Security Audit Report
+
+**Date**: 2026-05-13
+**Scope**: Azaion Admin API workspace (`/Users/obezdienie001/dev/azaion/suite/admin`) — full audit triggered by autodev cycle 1 completion (AZ-513, AZ-196, AZ-183, AZ-197).
+**Verdict**: **PASS_WITH_WARNINGS** (Critical: 0; High: 1 open — F-2 path traversal pre-existing; deferred to a separate ticket. F-1, F-3, D-1 closed in this audit.)
+
+## Summary
+
+| Severity | Count | Closed in this audit |
+|----------|-------|----------------------|
+| Critical | 0     | 0 |
+| High     | 3     | 3 — D-1 (`Newtonsoft.Json` 13.0.1 → 13.0.4), F-1 (OTA feature reverted — endpoints, service, entity, table, request DTOs, response DTO, e2e tests, master-key config field all deleted), F-3 (`RegisterDevice` reuses `RegisterUser`; UNIQUE INDEX `users_email_uidx` added) |
+| Medium   | 5     | 0 |
+| Low      | 5     | 0 |
+
+## Open / Deferred
+
+- **F-2** (path traversal via `dataFolder` route segment) remains open. It is pre-existing and unrelated to cycle-1 changes. Recommended: file as a separate ticket and close in a focused refactor (the fix needs both validation and a deployment-time review of `Content/` permissions). Not a blocker on this cycle.

+## Findings (severity-ranked)
+
+| # | Severity | Category | Location | Title |
+|---|----------|----------|----------|-------|
+| F-1 | **High** (CLOSED via revert) | A01 / A02 | (deleted) `Program.cs` `/get-update`, `ResourceUpdateService.cs` | `/get-update` exposed plaintext `EncryptionKey` to any authenticated caller. **Resolution**: the entire OTA feature was deleted — endpoints, `IResourceUpdateService`, `ResourceColumnEncryption`, `Resource` entity, `resources` table, `EncryptionMasterKey` config field, `apiUploaderPolicy`, `ResourceUpdateTests.cs`. AZ-183 is reverted; the OTA delivery model itself is obsolete in the target architecture. |
+| F-2 | **High** (open) | A01 | `ResourcesService.cs:20-25` + `Program.cs:201,213,219,224` | Path traversal via `dataFolder` route segment (pre-existing) — deferred to a separate ticket |
+| F-3 | **High** (CLOSED) | A04 / A07 | `env/db/06_users_email_unique.sql`, `UserService.cs` | `users.email` lacked UNIQUE → duplicate-row race in `RegisterUser` and `RegisterDevice`. **Resolution**: added migration `env/db/06_users_email_unique.sql` (`CREATE UNIQUE INDEX users_email_uidx ON public.users (email)`); refactored `RegisterUser` to drop the check-then-insert pattern and translate `Npgsql.PostgresException(SqlState=23505)` to `BusinessException(EmailExists)`; refactored `RegisterDevice` to delegate the row insert to `RegisterUser`. |
+| D-1 | **High** (CLOSED) | A06 | `Azaion.Common.csproj`, `Azaion.Services.csproj` | `Newtonsoft.Json 13.0.1` < patched line for GHSA-5crp-9r3c-p9vr — **bumped to 13.0.4** |
+| F-4 | Medium | A02 | `Program.cs:158-162` | `/devices` returns plaintext device password (accepted by design — needs `Cache-Control: no-store` and Swagger trim) |
+| F-5 | Medium | A05 | `ResourceUpdateService.cs:86-97` | `EncryptionMasterKey` validated lazily on first call instead of at startup |
+| F-6 | Medium | A05 | `Dockerfile:1,20-25` | API container runs as root |
+| F-7 | Medium | A02 / A07 | `Security.cs:11-12` | SHA-384 password hashing without per-user salt or KDF (pre-existing) |
+| F-8 | Medium | A04 / A07 | `Program.cs:137-143` | No rate limiting on `/login` (pre-existing) |
+| F-9 | Low | A05 | `LoginRequest.cs`, `SetUserQueueOffsetsRequest.cs` | DTOs lack `AbstractValidator<T>` |
+| F-10 | Low | — | `docker-compose.test.yml`, `appsettings.test.json` | Hardcoded credentials/JWT secret in test fixtures (test-only, accepted) |
+| F-11 | Low | A05 | `env/db/01_permissions.sql:2,7,12` | Placeholder DB passwords as setup template — needs header comment |
+| F-12 | Low | A09 | `ResourcesService.cs:63` | Unstructured `LogInformation($"...")` defeats Serilog property capture |
+| F-13 | Low | A02 | `Program.cs` | No HTTPS enforcement / HSTS in code (assumed at reverse proxy) |
+
+Detailed evidence and remediation steps for each finding are in `static_analysis.md` (F-N) and `dependency_scan.md` (D-N).
+
+## Cycle-1 Specific Verdict
+
+The four cycle-1 tasks introduced one **new** High finding (F-1) and amplified one pre-existing High (F-3). Both were closed before deploy:
+
+- **F-1 (resolved by revert)**: `/get-update` and `/resources/publish` are deleted; the entire OTA feature (AZ-183) is reverted. The user assessment was that the feature is itself a leftover from the installer-shipping era and is no longer needed in the target architecture (browser-only SaaS + fTPM-secured Jetsons).
+- **F-3 (resolved)**: `RegisterDevice` now delegates to `RegisterUser`; `users.email` has a UNIQUE INDEX; `RegisterUser` translates UNIQUE-violation to `EmailExists`. The duplicate-row race is closed atomically.
+- AZ-513 (`/classes` CRUD) and AZ-197 (hardware removal) introduce no new security findings. AZ-197 closes the prior `Hardware Fingerprint Binding` section of `security_approach.md` — the corresponding code, error codes, and DTOs are all gone.
+
+## Dependency Vulnerabilities
+
+| Package | CVE / Advisory | Severity | Status |
+|---------|---------------|----------|--------|
+| `Newtonsoft.Json` 13.0.1 → 13.0.4 | GHSA-5crp-9r3c-p9vr (DoS via deeply nested JSON) | High | **Closed in this audit** |
+
+`dotnet list package --vulnerable` returns clean for all five projects against the configured NuGet feeds. Three deprecated-but-not-vulnerable packages are tracked as forward-looking hygiene items in `dependency_scan.md` (`FluentValidation.AspNetCore` 11.3.0, `System.IdentityModel.Tokens.Jwt` 7.1.2, `xunit` 2.x).
+
+## Recommendations
+
+### Closed in this audit
+- **F-1**: OTA feature reverted in full (see "Findings" above).
+- **F-3**: UNIQUE INDEX added; `RegisterUser`/`RegisterDevice` consolidated; UNIQUE-violation translated to `EmailExists`.
+- **D-1**: `Newtonsoft.Json` bumped to 13.0.4.
+
+### Immediate (Critical / High — open)
+
+1. **F-2** (deferred): Add `dataFolder` validation (`[A-Za-z0-9_-]+` only, plus `Path.GetFullPath(combined).StartsWith(...)` post-check) in `ResourcesService.GetResourceFolder`. Pre-existing finding; file as a separate ticket.
+
+### Short-term (Medium)
+
+4. **F-4**: Add `Cache-Control: no-store, no-cache` to the `/devices` response and document the operator runbook entry (no body logging at the reverse proxy).
+5. **F-5**: Validate `ResourcesConfig.EncryptionMasterKey` at startup in non-Development environments.
+6. **F-6**: Add `USER app` to the final stage of `Dockerfile`; verify `Content/` and `logs/` are writable to `app` (UID 1654).
+7. **F-7**: Migrate password hashing to Argon2id with per-user salt (rolling rehash on next login).
+8. **F-8**: Enable ASP.NET Core 10 rate limiter on `/login` (e.g., 10 req/IP/min).
+
+### Long-term (Low / hardening)
+
+9. **F-9**: Add validators for `LoginRequest`, `SetUserQueueOffsetsRequest`.
+10. **F-11**: Add a header comment to `env/db/01_permissions.sql` flagging it as a template, or rename to `*.example.sql`.
+11. **F-12**: Convert the one unstructured log line in `ResourcesService.SaveResource` to structured form.
+12. **F-13**: Document the upstream HTTPS / HSTS / security-header chain in a deployment runbook; consider `app.UseHsts()` once the chain is documented.
+13. **CI gate**: introduce a build that runs `dotnet build && dotnet test && dotnet list package --vulnerable` and fails the pipeline on any vulnerability finding.
+
+## Verdict Logic
+
+- **PASS_WITH_WARNINGS** because exactly one pre-existing **High** finding remains open (F-2 path traversal). The two cycle-1-attributable Highs (F-1 regression, F-3 amplified) and the dependency High (D-1) were all closed during the audit.
+
+## Tracker Follow-Ups
+
+The following items should be filed as separate Jira tasks in the AZ project (per `.cursor/rules/tracker.mdc`). Do not write to the tracker as part of this audit — surface them to the user for prioritization first.

+# Static Analysis (SAST)
+
+**Date**: 2026-05-13
+**Method**: targeted code review of the cycle-1 surface (`/devices`, `/classes` CRUD, `/get-update`, `/resources/publish`) plus regression sweep over the pre-existing endpoints `/login`, `/users/*`, `/resources/*`. No automated SAST tool was run — all findings are manually identified with file/line evidence.
+
+**Post-audit status (2026-05-13)**: F-1 closed via revert of AZ-183 (OTA feature deleted end-to-end); F-3 closed via UNIQUE INDEX `users_email_uidx` + `RegisterUser`/`RegisterDevice` consolidation; F-5 closed automatically as a consequence of F-1; D-1 closed via `Newtonsoft.Json` 13.0.4 bump. F-2 (path traversal) remains open — pre-existing, deferred to a separate ticket.
+
+## Findings
+
+### F-1: `/get-update` exposes per-resource plaintext `EncryptionKey` to any authenticated caller (HIGH — cycle-1 regression — **CLOSED via revert**)
+
+- **Severity**: High
+- **Status**: **CLOSED** (2026-05-13) — the entire OTA feature was deleted: `/get-update` and `/resources/publish` endpoints, `IResourceUpdateService` / `ResourceUpdateService` / `ResourceColumnEncryption`, the `Resource` entity, the `resources` table, the `apiUploaderPolicy` policy, the `ResourcesConfig.EncryptionMasterKey` config field, and the `e2e/Azaion.E2E/Tests/ResourceUpdateTests.cs` test class. AZ-183 is reverted; the OTA delivery model is itself obsolete in the target architecture (browser-only SaaS + fTPM-secured Jetsons).
+- **Category**: Broken Access Control / Cryptographic Failures
+- **Original locations** (now deleted):
+  - `Azaion.AdminApi/Program.cs:301-312` — endpoint registration used `.RequireAuthorization()` (any logged-in user).
+  - `Azaion.Services/ResourceUpdateService.cs:39-48` — every `ResourceUpdateItem` returned to the caller contained `EncryptionKey = ResourceColumnEncryption.Decrypt(resource.EncryptionKey, MasterKey)`.
+- **Description**: The `resources.encryption_key` column was encrypted at rest with `ResourcesConfig.EncryptionMasterKey` precisely to mitigate DB compromise. But the application API decrypted and serialized that key into the HTTP response for any caller holding a valid JWT. A low-privilege user could submit `POST /get-update {Architecture, DevStage, CurrentVersions: {}}` and receive — for every published resource — `(CdnUrl, Sha256, EncryptionKey)`. With `EncryptionKey + CdnUrl`, the attacker could pull the encrypted blob from the CDN and decrypt it locally.
+- **Impact (had it shipped)**: Confidentiality of every published resource (firmware, model weights, installer payloads) reduced to "any authenticated session".
+- **Resolution rationale**: rather than tightening the policy or filtering the response, the user assessment is that the OTA delivery model itself is no longer needed — the suite is now installed/updated through the browser. Removing the surface eliminates the vulnerability and reduces the attack surface; F-5 (lazy-loaded `EncryptionMasterKey`) is also closed automatically.
+
+### F-2: Path traversal via `dataFolder` route segment (HIGH — pre-existing, re-flagged)
+
+- **Severity**: High
+- **Category**: Broken Access Control / Injection (Path)
+- **Locations**:
+  - `Azaion.Services/ResourcesService.cs:20-25` — `Path.Combine(ResourcesFolder, dataFolder)` accepts `..` and absolute paths without validation.
+  - Consumed by `Program.cs:201, 213, 219, 224` — `/resources/{dataFolder?}` (any-auth upload), `/resources/list/{dataFolder?}` (any-auth read), `/resources/clear/{dataFolder?}` (admin), `/resources/get/{dataFolder?}` (any-auth read).
+- **Description**: `Path.Combine("Content", "../../etc")` resolves to `etc`, escaping the configured root. A non-admin caller can:
+  - List arbitrary directories via `/resources/list/../../`.
+  - Read encrypted contents of arbitrary files via `/resources/get/../../<path>` provided they know a filename.
+  - Write into arbitrary directories the process can write to via `/resources/<traversal>` upload.
+- **Impact**: Server-side file disclosure and arbitrary file write bounded by process privileges. Pre-existing — already noted in `_docs/00_problem/security_approach.md` "Known Security Observations" #3 — but the cycle-1 audit re-confirms it is unmitigated.
+- **Remediation**:
+  - Sanitize `dataFolder`: reject any value containing `..`, `/`, `\`, or starting with a drive letter; alternatively, allow only `[A-Za-z0-9_-]+` segments.
+  - Verify that the resolved absolute path starts with the resolved `ResourcesFolder` absolute path — `Path.GetFullPath(combined).StartsWith(Path.GetFullPath(root))` — and reject otherwise.
+
+### F-3: `users.email` lacks a UNIQUE constraint — race in both `RegisterUser` and (cycle-1) `RegisterDevice` (HIGH — **CLOSED**)
+
+- **Severity**: High
+- **Status**: **CLOSED** (2026-05-13).
+- **Resolution**:
+  - Added migration `env/db/06_users_email_unique.sql` containing `CREATE UNIQUE INDEX IF NOT EXISTS users_email_uidx ON public.users (email);`. The migration is wired into `e2e/db-init/00_run_all.sh`.
+  - `Azaion.Services/UserService.cs` — `RegisterUser` no longer check-then-inserts. It catches `Npgsql.PostgresException` with `SqlState == PostgresErrorCodes.UniqueViolation` (23505) and rethrows as `BusinessException(EmailExists)`. The race is closed atomically by the index.
+  - `RegisterDevice` was refactored to delegate the row insert to `RegisterUser` (the user's explicit guidance: "reuse the code in the implementation RegisterDevice -> should call RegisterUser"). Two concurrent provisioning calls that race on the same serial now hit the UNIQUE INDEX and surface `BusinessException(EmailExists)`; the caller can retry.
+- **Residual risk**: a Postgres sequence for device serials (`device_serial_seq`) would also remove the serial-allocation race window and avoid the retry. Out of scope for this audit fix; can be added as a follow-up.
+
+### F-4: `/devices` returns plaintext device password in the JSON body (MEDIUM — accepted by design, hardening required)
+
+- **Severity**: Medium
+- **Category**: Cryptographic Failures / Data Exposure
+- **Locations**:
+  - `Azaion.AdminApi/Program.cs:158-162`
+  - `Azaion.Services/UserService.cs:84-89` (assembles `RegisterDeviceResponse`)
+- **Description**: The endpoint deliberately returns the plaintext device password "exactly once" so the provisioning script can write it to `device.conf`. ApiAdmin-only, so abuse blast radius is bounded — but the password is reachable via:
+  - Reverse-proxy access logs that capture response bodies
+  - Browser DevTools / network history when triggered from the admin UI
+  - Swagger UI's "Try it out" response panel in any environment where Swagger is exposed (today: `IsDevelopment()` only — verified).
+- **Impact**: Credentials may persist in unintended log sinks beyond their intended one-shot consumption.
+- **Remediation**:
+  - Set response headers `Cache-Control: no-store, no-cache`, `Pragma: no-cache` on this endpoint specifically.
+  - Document an SRE runbook entry: do NOT enable response-body logging on the reverse proxy for `POST /devices`.
+  - Optional: add an `X-One-Shot-Credential: true` header so log scrubbers can match-and-mask.
+
+### F-5: `EncryptionMasterKey` validation is lazy — first failing request, not startup (MEDIUM — **CLOSED**)
+
+- **Severity**: Medium
+- **Status**: **CLOSED** (2026-05-13) — `ResourcesConfig.EncryptionMasterKey` and the `ResourceUpdateService.MasterKey` getter were both deleted along with the OTA feature (see F-1). The lazy-validation surface no longer exists; `appsettings.json` and `docker-compose.test.yml` no longer reference the field.
+
+### F-6: API container runs as root (MEDIUM)
+
+- **Severity**: Medium
+- **Category**: Security Misconfiguration
+- **Location**: `Dockerfile:1, 20-25`
+- **Description**: `mcr.microsoft.com/dotnet/aspnet:10.0` defaults to `root`. There is no `USER` directive after `FROM base AS final`. CIS Docker Benchmark §4.1 calls this out: a process running as root inside the container has more privileges than necessary, and a container escape (CVE-2024-21626 class) becomes a root-on-host exploit.
+- **Impact**: Defense-in-depth weakness. No specific exploit, but failure mode is severe.
+- **Remediation**: Add `USER app` to the final stage (the .NET 10 base image already provisions a non-root `app` user, UID 1654). The Content/log directory permissions need to be checked once the change is made.
+
+### F-7: SHA-384 password hashing without per-user salt or KDF (MEDIUM — pre-existing)
+
+- **Severity**: Medium
+- **Category**: Cryptographic Failures
+- **Locations**:
+  - `Azaion.Services/Security.cs:11-12` — `ToHash()` hashes raw UTF-8 bytes with SHA-384.
+  - `Azaion.Services/UserService.cs:44, 110, 78` — used for `RegisterUser`, `ValidateUser`, `RegisterDevice` (cycle-1 added the `RegisterDevice` call site).
+- **Description**: SHA-384 is a fast cryptographic hash, not a password-hashing algorithm. No per-user salt, no work factor, no memory hardness. A leaked `password_hash` column lets an offline attacker grind ~10⁹ candidates per second per GPU.
+- **Impact**: Database leak directly compromises all user passwords in tractable time.
+- **Remediation**: Migrate to Argon2id (e.g., `Konscious.Security.Cryptography.Argon2`) or bcrypt (`BCrypt.Net-Next`) with per-user salt. Two-phase rollout: rehash on next successful login until the SHA-384 column is empty, then drop it.
+
+### F-8: No rate limiting on `/login` (MEDIUM — pre-existing)
+
+- **Severity**: Medium
+- **Category**: Auth Failures
+- **Location**: `Azaion.AdminApi/Program.cs:137-143`
+- **Description**: Combined with F-7, an attacker who can reach `/login` can brute-force credentials. ASP.NET Core 10 ships `AddRateLimiter()` out of the box.
+- **Remediation**: Add a fixed-window or sliding-window limiter scoped to `/login` (e.g., 10 requests / IP / minute, with exponential backoff).
+
+### F-9: `LoginRequest`, `SetUserQueueOffsetsRequest` lack server-side validation (LOW — pre-existing)
+
+- **Severity**: Low
+- **Category**: Security Misconfiguration
+- **Locations**:
+  - `Azaion.Common/Requests/LoginRequest.cs` — no validator class
+  - `Azaion.Common/Requests/SetUserQueueOffsetsRequest.cs` — no validator class
+- **Description**: Other request DTOs use `AbstractValidator<T>` (`RegisterUserValidator`, `GetUpdateValidator`, etc.). These two are unguarded — `LoginRequest` accepts any-length email/password, `SetUserQueueOffsetsRequest` accepts any email shape and any offsets payload.
+- **Remediation**: Add validators with `EmailAddress()` + `MinimumLength(12)` (matching `RegisterUserValidator`) and bounds checks for `Offsets`.
+
+### F-10: Hardcoded credentials and JWT secret in test fixtures (LOW — accepted)
+
+- **Severity**: Low
+- **Category**: Hardcoded Credentials
+- **Locations**:
+  - `docker-compose.test.yml:31-33, 37` — DB credentials, JWT secret, encryption master key as compose env vars.
+  - `e2e/Azaion.E2E/appsettings.test.json:4-7` — `AdminPassword`, `UploaderPassword`, `JwtSecret`.
+- **Description**: These are e2e-only and consistent across the harness. They are NOT used in production builds. Flagged here for visibility only — they MUST NEVER drift into the prod compose / appsettings.
+- **Remediation**: Add a CI guard: fail the pipeline if any of these literals appear in `Azaion.AdminApi/appsettings.json` or `Azaion.AdminApi/appsettings.Production.json`.
+
+### F-11: `env/db/01_permissions.sql` ships placeholder DB passwords as a setup template (LOW)
+
+- **Severity**: Low
+- **Category**: Hardcoded Credentials (template / docs)
+- **Location**: `env/db/01_permissions.sql:2, 7, 12` — `superadmin-pass`, `admin-pass`, `readonly-pass`.
+- **Description**: The file is the operator setup template. The e2e harness immediately overrides these with `test_password` (`e2e/db-init/99_test_seed.sql:1-2`), so the placeholders never reach a runtime. But the file lives at `env/db/` with no header comment marking it template-only.
+- **Remediation**: Add a top-of-file comment `-- TEMPLATE: replace placeholder passwords before applying to any environment.` Consider renaming to `01_permissions.example.sql`.
+
+### F-12: Unstructured logging in `ResourcesService.SaveResource` (LOW)
+
+- **Severity**: Low
+- **Category**: Logging Failures (operational)
+- **Location**: `Azaion.Services/ResourcesService.cs:63` — `logger.LogInformation($"Resource {data.FileName} Saved Successfully")`.
+- **Description**: String interpolation defeats Serilog's structured property capture; the `FileName` is not searchable as a field. Not a security issue, but flagged because the security-event-logging principle (audit trail) requires structured fields.
+- **Remediation**: `logger.LogInformation("Resource {FileName} saved successfully", data.FileName);`
+
+### F-13: No HTTPS enforcement in application code (LOW — pre-existing, design)
+
+- **Severity**: Low
+- **Category**: Cryptographic Failures
+- **Location**: `Azaion.AdminApi/Program.cs` — no `app.UseHttpsRedirection()`, no `Hsts`.
+- **Description**: HTTPS is assumed at the reverse proxy. Acceptable design choice if and only if the reverse proxy and its config are part of the secure boundary.
+- **Remediation**: Document the assumption in a deployment runbook; consider `UseHsts()` when the upstream chain terminates TLS.
+
+## Self-verification

+- [x] All source directories scanned (`Azaion.AdminApi/`, `Azaion.Services/`, `Azaion.Common/`, `env/db/`, `Dockerfile`)
+- [x] Each finding has file path and (where relevant) line numbers

+# Performance Test Report — Cycle 1
+
+**Date**: 2026-05-13

+```
+
+## Environment
+
+- Host: macOS 25.4.0 (Apple Silicon)
+- Docker Desktop, single host, no resource throttling
+- SUT: `system-under-test` container built from repo `Dockerfile`, running on `http://localhost:8080`
+- DB: `test-db` (postgres:16-alpine), in-process to the same Docker host
+- Seed: functional fixtures from `e2e/db-init/00_run_all.sh` + `99_test_seed.sql`, plus 500 dummy `perf-user-NNNNN@perf.azaion.com` rows inserted by `run-performance-tests.sh` after SUT readiness check
+- k6 v2.0.0 (Homebrew bottle, arm64)
+
+## Caveats / coverage gaps
+
+1. **Single-host run** — perf was measured with k6 and the SUT on the same machine, no network RTT, no inter-AZ latency. Production numbers will be higher; the 15×/6.5× headroom should absorb that comfortably for an internal admin API.
+2. **No DB warmup phase** — both p99/max values include cold-cache outliers (login max 630ms, user-list max ~2s). The p95 already excludes those, but a future iteration could add a 5–10s warmup ramp.
+3. **No realistic load on the user-list filter path** — only the unfiltered `GET /users` is exercised. Adding a `?searchEmail=` variant would catch the case where the LinqToDB `WhereIf` fails to fold into the SQL.
+4. **No `/classes` CRUD perf coverage** — cycle 1 added these endpoints (AZ-513) but the perf spec was not extended. Recommend adding a NFT-PERF-05 in the next test-spec sync.
+5. **`acceptance_criteria.md` is stale post-cycle-1** — AC-13/14/15/16 (hardware binding) and AC-17–24 (resource management) reference deleted features. Step 12 (Test-Spec Sync) of cycle 1 missed this. Surface in Step 17 retro and clean up in cycle 2.
+
+## Recommendations for next cycle
+
+- **Cycle 2 test-spec sync must prune AC-13..24** and add an AC for `/classes` CRUD.
+- **Add NFT-PERF-05** for `POST /classes` and `PATCH /classes/{id}` to cover the new write paths.
+- **CI gate**: wire `scripts/run-performance-tests.sh` into the deploy pipeline so threshold breaches block release. Today it is run-on-demand only.
+
+## Verdict logic
+
+PASS — all thresholds met, no failed checks, no errors, no warn-band scenarios. Auto-chain to Step 16 (Deploy).

+
+## Detection
+
+How was the issue first noticed?
+
+- Alert: which one? Was the threshold appropriate? Did it fire in time?
+- User report: how did the user reach us? How long after the incident started?
+- Smoke test: which step? (1–6 from `scripts/smoke.sh`)
+
+## Impact
+
+- User impact (number of failed requests, revenue, data loss — be specific)
+- Internal impact (engineering time, lost productivity)
+- Regulatory / compliance impact (if any)
+
+## Root cause
+
+One paragraph. Include the specific commit / config change / external event. Link to the failing test / log line that proves the cause.
+
+> Avoid "human error" as a root cause — it's almost never a useful answer. Focus on the system gap that allowed the human action to cause harm.
+
+## Repair
+
+- What action mitigated the user impact? (Rollback, config change, restart, etc.)
+- What action fully resolved the issue? (Code fix, infrastructure change, etc.)
+- Were there any side-effects of the repair? (Data loss, missed messages, etc.)
+
+## Detection gaps
+
+What would we want the system to have done instead?
+
+- New alert(s) needed? With what threshold?
+- New health check needed? At what level?
+- Better dashboard panel?
+- New smoke-test step?

+## First-time bootstrap on a fresh host
+
+```bash
+# 1. Install sops + age on the host
+sudo apt-get install -y sops age
+
+# 2. Generate the host's age keypair
+sudo install -d -m 0700 /etc/azaion

+## Rotation
+
+See `_docs/04_deploy/environment_strategy.md` §3 for the per-secret rotation cadence and procedure.
+
+## What goes where
+
+- **Public env (staging.public.env / production.public.env)** — anything that is NOT a secret: hostname, port, container name, JWT issuer/audience, resource folder names. Reviewable in PRs.
+- **Encrypted env (staging.env / production.env)** — DB connection strings (with passwords), `JwtConfig__Secret`, `REGISTRY_USER`, `REGISTRY_TOKEN`, anything else sensitive. NEVER readable in plain text outside the host.
+
+## Schema (variables that MUST be in the encrypted file)
+
+```
+ASPNETCORE_ConnectionStrings__AzaionDb=Host=...;Port=4312;Database=azaion;Username=azaion_reader;Password=...
+ASPNETCORE_ConnectionStrings__AzaionDbAdmin=Host=...;Port=4312;Database=azaion;Username=azaion_admin;Password=...
+ASPNETCORE_JwtConfig__Secret=<>= 32 random bytes>
+REGISTRY_USER=<registry account>
+REGISTRY_TOKEN=<registry token>
+```
+
+The deploy script will fail-fast if any of the first three are missing once the container starts.
