BEFORE invoking, check if the question is specific enough to research directly — if underspecified (e.g., \"what car to buy\" without budget/use-case/region), ask 2-3 clarifying questions to narrow scope. Then pass the refined question as args, weaving the answers in.\n- frontend-design:frontend-design: Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.\n- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- verify: Verify that a code change actually does what it's supposed to by running the app and observing behavior. Use when asked to verify a PR, confirm a fix works, test a change manually, check that a feature works, or validate local changes before pushing.\n- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.\nTRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).\nSKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).\n- init: Initialize a new CLAUDE.md file with codebase documentation\n- review: Review a pull request\n- security-review: Complete a security review of the pending changes on the current branch","skillCount":15,"isInitial":true,"names":["deep-research","frontend-design:frontend-design","update-config","keybindings-help","verify","code-review","simplify","fewer-permission-prompts","loop","schedule","claude-api","run","init","review","security-review"]},"type":"attachment","uuid":"1e29aa0d-ba33-41e2-9ea5-63b917e4fe0b","timestamp":"2026-06-17T04:40:38.341Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"bce9928c-3f8b-4b95-aa53-56af445a9bbc","version":"2.1.179","gitBranch":"feature/558-replace-gorilla-sessions","slug":"replace-the-gorilla-sessions-package-atomic-metcalfe"}

Now I have all the information I need. Let me compile my comprehensive report.\n\n## Comprehensive Authentication and HTTP Server Setup Report\n\nI've completed a thorough exploration of the authentication and HTTP server setup. Here's my detailed findings:\n\n---\n\n### 1. Authentication Structure (`/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/auth.go`)\n\n**Authentication Struct** (lines 119-127):\n```go\ntype Authentication struct {\n    sessionStore   *sessions.CookieStore  // GORILLA SESSIONS - KEY FIELD\n    LdapAuth       *LdapAuthenticator\n    JwtAuth        *JWTAuthenticator\n    LocalAuth      *LocalAuthenticator\n    authenticators []Authenticator\n    SessionMaxAge  time.Duration\n}\n```\n\n**Key Session Management Methods:**\n\n- **Session Creation (line 321-354)**: `SaveSession(rw http.ResponseWriter, r *http.Request, user *schema.User) error`\n  - Creates new session via `auth.sessionStore.New(r, \"session\")` (line 322)\n  - Sets MaxAge, Secure, SameSite, HttpOnly flags\n  - Stores: `username`, `projects`, `roles`, `authSource` in session values\n  - Saves via `auth.sessionStore.Save(r, rw, session)` (line 347)\n\n- **Session Retrieval (line 129-180)**: `AuthViaSession(rw http.ResponseWriter, r *http.Request) (*schema.User, error)`\n  - Gets session via `auth.sessionStore.Get(r, \"session\")` (line 133)\n  - Validates username, projects, roles, authSource from `session.Values`\n  - Returns nil for new sessions\n\n- **Session Destruction (line 610-628)**: `Logout(onsuccess http.Handler) http.Handler`\n  - Gets session via `auth.sessionStore.Get(r, \"session\")` (line 612)\n  - Invalidates by setting `session.Options.MaxAge = -1` (line 619)\n  - Saves invalidated session\n\n**Initialization (lines 182-274)**: `Init(authCfg *json.RawMessage)`\n- Reads `SESSION_KEY` environment variable (base64-encoded 32 random bytes) (line 189)\n- Creates `sessions.CookieStore` with decoded key (line 202 or 208)\n- Parses `SessionMaxAge` from config (line 211-213)\n- Initializes all authenticators (LDAP, JWT, Local) as a chain (line 383-420)\n\n---\n\n### 2. HTTP Router Setup (`/Users/jan/prg/ClusterCockpit/cc-backend/cmd/cc-backend/server.go`)\n\n**Router Library**: **go-chi/chi/v5** (import line 41)\n\n**Server Structure** (lines 60-66):\n```go\ntype Server struct {\n    router        chi.Router\n    server        *http.Server\n    restAPIHandle *api.RestAPI\n    natsAPIHandle *api.NatsAPI\n}\n```\n\n**Router Initialization** (lines 92-390):\n- `chi.NewRouter()` created in `NewServer()` (line 82)\n- Global middleware registered BEFORE routes (lines 126-182):\n  - Request logging\n  - Gzip compression\n  - Error recovery\n  - CORS handling\n  - Security headers (X-Content-Type-Options, X-Frame-Options, CSP, HSTS)\n  - CSRF defense (Sec-Fetch-Site validation)\n\n**Route Groups and Authentication Middleware:**\n\n1. **Public routes** (lines 195-207):\n   - `/login`, `/jwt-login`, `/logout`, `/imprint`, `/privacy`\n   - No authentication required\n\n2. **Secured Routes** (lines 247-273):\n   - Uses middleware: `authHandle.Auth(next, onfailureResponse)` (line 250)\n   - Wraps both session AND JWT auth together\n   - Calls `AuthViaSession()` if JWT fails (auth.go:435)\n   - GraphQL, search, and template routes mounted here\n\n3. **REST API Routes** (lines 276-285):\n   - Uses middleware: `authHandle.AuthAPI(next, onFailureResponse)` (line 281)\n   - JWT-only authentication (`AuthViaJWT` first, no session fallback)\n   - Mounted via `s.restAPIHandle.MountAPIRoutes(securedapi)` (line 284)\n\n4. **Metric Store API Routes** (lines 288-295):\n   - Uses middleware: `authHandle.AuthMetricStoreAPI(next, onFailureResponse)` (line 291)\n   - JWT-only with specific role checks\n\n5. **User API Routes** (lines 299-306):\n   - Uses middleware: `authHandle.AuthUserAPI(next, onFailureResponse)` (line 302)\n\n6. **Config API Routes** (lines 310-317):\n   - Uses middleware: `authHandle.AuthConfigAPI(next, onFailureResponse)` (line 313)\n   - Session-only auth (admin exclusive)\n\n7. **Frontend API Routes** (lines 320-327):\n   - Uses middleware: `authHandle.AuthFrontendAPI(next, onFailureResponse)` (line 323)\n   - Session-only auth\n\n**Key Auth Middleware Pattern** (lines 247-263):\n```go\nsecured.Use(func(next http.Handler) http.Handler {\n    return authHandle.Auth(next,\n        func(rw http.ResponseWriter, r *http.Request, err error) {\n            // on-failure handler: renders login.tmpl\n        })\n})\n```\n\n---\n\n### 3. Configuration Loading\n\n**Main Config** (`/Users/jan/prg/ClusterCockpit/cc-backend/internal/config/config.go`):\n- `SessionMaxAge` field (line 49): `string` type, parsed as Go duration\n- Default: `\"168h\"` (7 days) (line 145)\n- Schema location: `/Users/jan/prg/ClusterCockpit/cc-backend/internal/config/schema.go` (lines 55-58)\n- Read from `config.json` during app startup\n\n**Auth Config** (`/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/schema.go`):\n- Three top-level auth configs: `ldap`, `jwts`, `oidc`\n- JWT config requires `max-age` (duration string)\n- OIDC config optional but has `sync-user-on-login`, `update-user-on-login`\n- LDAP config has `sync-user-on-login`, `update-user-on-login`\n\n**Environment Variables**:\n- `SESSION_KEY`: Base64-encoded 32 random bytes (required if auth enabled)\n- `JWT_PUBLIC_KEY`, `JWT_PRIVATE_KEY`: Ed25519 keys for JWT signing\n- `OID_CLIENT_ID`, `OID_CLIENT_SECRET`: OIDC client credentials\n- `LDAP_ADMIN_PASSWORD`: For LDAP sync operations\n\n---\n\n### 4. User Extraction from Request (Cookie → Session → User)\n\n**Full Extraction Path:**\n\n1. **Middleware Auth Handler** (`auth.go:423-451`): `Auth(onsuccess, onfailure) http.Handler`\n   - First tries: `auth.JwtAuth.AuthViaJWT(rw, r)` (line 428)\n   - If no JWT, tries: `auth.AuthViaSession(rw, r)` (line 435)\n\n2. **Session Extraction** (`auth.go:129-180`): `AuthViaSession(rw, r) (*schema.User, error)`\n   ```\n   Request Cookie (\"session\") \n     → sessionStore.Get(r, \"session\") \n     → session.Values[\"username\"] \n     → Builds *schema.User from session values\n   ```\n   - Reads cookie via gorilla sessions (line 133)\n   - Extracts from `session.Values`: `username`, `projects`, `roles`, `authSource`\n   - Returns fully-formed `*schema.User` object\n\n3. **Context Injection** (`auth.go:404,443`):\n   - `ctx := context.WithValue(r.Context(), repository.ContextUserKey, user)`\n   - User injected into request context with key `ContextUserKey` (\"user\")\n\n4. **User Retrieval in Handlers** (`/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/user.go:505-513`):\n   ```go\n   func GetUserFromContext(ctx context.Context) *schema.User {\n       x := ctx.Value(ContextUserKey)\n       return x.(*schema.User)\n   }\n   ```\n\n**Cookie Structure**:\n- Name: `\"session\"`\n- Contains: Encrypted gob-encoded session data (gorilla sessions format)\n- Options set in `SaveSession()`:\n  - `MaxAge`: From config `SessionMaxAge` (default 168h)\n  - `HttpOnly`: true\n  - `SameSite`: `http.SameSiteLaxMode` (Lax)\n  - `Secure`: true if TLS or `X-Forwarded-Proto: https`, else false\n\n---\n\n### 5. Other Auth Mechanisms and Session Integration\n\nAll auth mechanisms follow the same Authenticator interface pattern and call `SaveSession()` after successful login.\n\n**A. Local Password Authentication** (`/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/local.go:36-48`)\n- `Login()`: Validates bcrypt password, returns user\n- Called via login handler chain (auth.go:356-420)\n- Session created at line 399: `auth.SaveSession(rw, r, user)`\n\n**B. LDAP Authentication** (`/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/ldap.go:122-142`)\n- `Login()`: LDAP bind authentication\n- `CanLogin()`: Checks if `AuthViaLDAP`, or creates user if `SyncUserOnLogin` enabled\n- Calls `handleLdapUser()` for sync/update (line 115, 318)\n- Session created via standard login handler chain (auth.go:399)\n\n**C. JWT Cookie Session Authentication** (`/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/jwtCookieSession.go`)\n- Cross-login via JWT in cookie (`CookieName` from config)\n- `CanLogin()`: Reads JWT cookie, extracts user\n- `Login()`: Verifies JWT signature\n- Session created via standard login handler chain (auth.go:399)\n\n**D.

Let me compile my comprehensive report.\n\n## Comprehensive Authentication and HTTP Server Setup Report\n\nI've completed a thorough exploration of the authentication and HTTP server setup. Here's my detailed findings:\n\n---\n\n### 1. Authentication Structure (`/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/auth.go`)\n\n**Authentication Struct** (lines 119-127):\n```go\ntype Authentication struct {\n    sessionStore   *sessions.CookieStore  // GORILLA SESSIONS - KEY FIELD\n    LdapAuth       *LdapAuthenticator\n    JwtAuth        *JWTAuthenticator\n    LocalAuth      *LocalAuthenticator\n    authenticators []Authenticator\n    SessionMaxAge  time.Duration\n}\n```\n\n**Key Session Management Methods:**\n\n- **Session Creation (line 321-354)**: `SaveSession(rw http.ResponseWriter, r *http.Request, user *schema.User) error`\n  - Creates new session via `auth.sessionStore.New(r, \"session\")` (line 322)\n  - Sets MaxAge, Secure, SameSite, HttpOnly flags\n  - Stores: `username`, `projects`, `roles`, `authSource` in session values\n  - Saves via `auth.sessionStore.Save(r, rw, session)` (line 347)\n\n- **Session Retrieval (line 129-180)**: `AuthViaSession(rw http.ResponseWriter, r *http.Request) (*schema.User, error)`\n  - Gets session via `auth.sessionStore.Get(r, \"session\")` (line 133)\n  - Validates username, projects, roles, authSource from `session.Values`\n  - Returns nil for new sessions\n\n- **Session Destruction (line 610-628)**: `Logout(onsuccess http.Handler) http.Handler`\n  - Gets session via `auth.sessionStore.Get(r, \"session\")` (line 612)\n  - Invalidates by setting `session.Options.MaxAge = -1` (line 619)\n  - Saves invalidated session\n\n**Initialization (lines 182-274)**: `Init(authCfg *json.RawMessage)`\n- Reads `SESSION_KEY` environment variable (base64-encoded 32 random bytes) (line 189)\n- Creates `sessions.CookieStore` with decoded key (line 202 or 208)\n- Parses `SessionMaxAge` from config (line 211-213)\n- Initializes all authenticators (LDAP, JWT, Local) as a chain (line 383-420)\n\n---\n\n### 2. HTTP Router Setup (`/Users/jan/prg/ClusterCockpit/cc-backend/cmd/cc-backend/server.go`)\n\n**Router Library**: **go-chi/chi/v5** (import line 41)\n\n**Server Structure** (lines 60-66):\n```go\ntype Server struct {\n    router        chi.Router\n    server        *http.Server\n    restAPIHandle *api.RestAPI\n    natsAPIHandle *api.NatsAPI\n}\n```\n\n**Router Initialization** (lines 92-390):\n- `chi.NewRouter()` created in `NewServer()` (line 82)\n- Global middleware registered BEFORE routes (lines 126-182):\n  - Request logging\n  - Gzip compression\n  - Error recovery\n  - CORS handling\n  - Security headers (X-Content-Type-Options, X-Frame-Options, CSP, HSTS)\n  - CSRF defense (Sec-Fetch-Site validation)\n\n**Route Groups and Authentication Middleware:**\n\n1. **Public routes** (lines 195-207):\n   - `/login`, `/jwt-login`, `/logout`, `/imprint`, `/privacy`\n   - No authentication required\n\n2. **Secured Routes** (lines 247-273):\n   - Uses middleware: `authHandle.Auth(next, onfailureResponse)` (line 250)\n   - Wraps both session AND JWT auth together\n   - Calls `AuthViaSession()` if JWT fails (auth.go:435)\n   - GraphQL, search, and template routes mounted here\n\n3. **REST API Routes** (lines 276-285):\n   - Uses middleware: `authHandle.AuthAPI(next, onFailureResponse)` (line 281)\n   - JWT-only authentication (`AuthViaJWT` first, no session fallback)\n   - Mounted via `s.restAPIHandle.MountAPIRoutes(securedapi)` (line 284)\n\n4. **Metric Store API Routes** (lines 288-295):\n   - Uses middleware: `authHandle.AuthMetricStoreAPI(next, onFailureResponse)` (line 291)\n   - JWT-only with specific role checks\n\n5. **User API Routes** (lines 299-306):\n   - Uses middleware: `authHandle.AuthUserAPI(next, onFailureResponse)` (line 302)\n\n6. **Config API Routes** (lines 310-317):\n   - Uses middleware: `authHandle.AuthConfigAPI(next, onFailureResponse)` (line 313)\n   - Session-only auth (admin exclusive)\n\n7. **Frontend API Routes** (lines 320-327):\n   - Uses middleware: `authHandle.AuthFrontendAPI(next, onFailureResponse)` (line 323)\n   - Session-only auth\n\n**Key Auth Middleware Pattern** (lines 247-263):\n```go\nsecured.Use(func(next http.Handler) http.Handler {\n    return authHandle.Auth(next,\n        func(rw http.ResponseWriter, r *http.Request, err error) {\n            // on-failure handler: renders login.tmpl\n        })\n})\n```\n\n---\n\n### 3. Configuration Loading\n\n**Main Config** (`/Users/jan/prg/ClusterCockpit/cc-backend/internal/config/config.go`):\n- `SessionMaxAge` field (line 49): `string` type, parsed as Go duration\n- Default: `\"168h\"` (7 days) (line 145)\n- Schema location: `/Users/jan/prg/ClusterCockpit/cc-backend/internal/config/schema.go` (lines 55-58)\n- Read from `config.json` during app startup\n\n**Auth Config** (`/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/schema.go`):\n- Three top-level auth configs: `ldap`, `jwts`, `oidc`\n- JWT config requires `max-age` (duration string)\n- OIDC config optional but has `sync-user-on-login`, `update-user-on-login`\n- LDAP config has `sync-user-on-login`, `update-user-on-login`\n\n**Environment Variables**:\n- `SESSION_KEY`: Base64-encoded 32 random bytes (required if auth enabled)\n- `JWT_PUBLIC_KEY`, `JWT_PRIVATE_KEY`: Ed25519 keys for JWT signing\n- `OID_CLIENT_ID`, `OID_CLIENT_SECRET`: OIDC client credentials\n- `LDAP_ADMIN_PASSWORD`: For LDAP sync operations\n\n---\n\n### 4. User Extraction from Request (Cookie → Session → User)\n\n**Full Extraction Path:**\n\n1. **Middleware Auth Handler** (`auth.go:423-451`): `Auth(onsuccess, onfailure) http.Handler`\n   - First tries: `auth.JwtAuth.AuthViaJWT(rw, r)` (line 428)\n   - If no JWT, tries: `auth.AuthViaSession(rw, r)` (line 435)\n\n2. **Session Extraction** (`auth.go:129-180`): `AuthViaSession(rw, r) (*schema.User, error)`\n   ```\n   Request Cookie (\"session\") \n     → sessionStore.Get(r, \"session\") \n     → session.Values[\"username\"] \n     → Builds *schema.User from session values\n   ```\n   - Reads cookie via gorilla sessions (line 133)\n   - Extracts from `session.Values`: `username`, `projects`, `roles`, `authSource`\n   - Returns fully-formed `*schema.User` object\n\n3. **Context Injection** (`auth.go:404,443`):\n   - `ctx := context.WithValue(r.Context(), repository.ContextUserKey, user)`\n   - User injected into request context with key `ContextUserKey` (\"user\")\n\n4. **User Retrieval in Handlers** (`/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/user.go:505-513`):\n   ```go\n   func GetUserFromContext(ctx context.Context) *schema.User {\n       x := ctx.Value(ContextUserKey)\n       return x.(*schema.User)\n   }\n   ```\n\n**Cookie Structure**:\n- Name: `\"session\"`\n- Contains: Encrypted gob-encoded session data (gorilla sessions format)\n- Options set in `SaveSession()`:\n  - `MaxAge`: From config `SessionMaxAge` (default 168h)\n  - `HttpOnly`: true\n  - `SameSite`: `http.SameSiteLaxMode` (Lax)\n  - `Secure`: true if TLS or `X-Forwarded-Proto: https`, else false\n\n---\n\n### 5. Other Auth Mechanisms and Session Integration\n\nAll auth mechanisms follow the same Authenticator interface pattern and call `SaveSession()` after successful login.\n\n**A. Local Password Authentication** (`/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/local.go:36-48`)\n- `Login()`: Validates bcrypt password, returns user\n- Called via login handler chain (auth.go:356-420)\n- Session created at line 399: `auth.SaveSession(rw, r, user)`\n\n**B. LDAP Authentication** (`/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/ldap.go:122-142`)\n- `Login()`: LDAP bind authentication\n- `CanLogin()`: Checks if `AuthViaLDAP`, or creates user if `SyncUserOnLogin` enabled\n- Calls `handleLdapUser()` for sync/update (line 115, 318)\n- Session created via standard login handler chain (auth.go:399)\n\n**C. JWT Cookie Session Authentication** (`/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/jwtCookieSession.go`)\n- Cross-login via JWT in cookie (`CookieName` from config)\n- `CanLogin()`: Reads JWT cookie, extracts user\n- `Login()`: Verifies JWT signature\n- Session created via standard login handler chain (auth.go:399)\n\n**D. JWT Bearer Token Authentication** (`/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/jwt.go:71-100`)\n- `AuthViaJWT()`: Reads from `X-Auth-Token` or `Authorization: Bearer` header\n- Parses Ed25519-signed JWT\n- Extracts user claims directly (no session created)\n- **Does NOT create sessions** — used for API clients\n\n**E. OpenID Connect (OIDC)** (`/Users/jan/prg/ClusterCockpit/cc-backend/internal/auth/oidc.go`)\n- `OAuth2Callback()`: Exchanges code for token, verifies ID token nonce\n- Extracts claims: `preferred_username`, `name`, `realm_access.roles`, `resource_access` (Keycloak), `projects`\n- Maps role names (`\"user\"`, `\"admin\"`, `\"manager\"`, `\"support\"`) to schema roles (line 238-248)\n- Calls `handleOIDCUser()` for sync/update (line 268)\n- **Creates session** at line 271: `oa.authentication.SaveSession(rw, r, user)`\n- Redirects to `/` (line 278)\n\n---\n\n### 6. Session Middleware Installation Points\n\n**Installation Pattern**: Middleware registered as global router middleware before route definitions:\n- Line 126-182: Global middleware (logging, compression, recovery, CORS, headers, CSRF)\n- Line 250-262: Auth middleware in secured group\n- Line 281, 291, 302, 313, 323: Individual auth middlewares for API routes\n\n**Session store is NOT middleware** — it's instance variable `auth.sessionStore` (gorilla CookieStore) used by auth handlers on-demand via `AuthViaSession()` and `SaveSession()` methods.\n\n---\n\n### 7.

The migration is cleanly scoped to `internal/auth/auth.go` (the `sessionStore` field and its 3 methods: `AuthViaSession`, `SaveSession`, `Logout`) plus initialization in `Init()`.\n\nOne architectural point drives the design: **gorilla `CookieStore` is stateless** (all session data lives encrypted in the cookie, so sessions survive restarts as long as `SESSION_KEY` is stable), whereas **scs/v2 is server-side** (only a random token in the cookie; data lives in a store). This changes two things I need your input on.\n\nNote also: scs's idiomatic `LoadAndSave` middleware buffers the *entire* HTTP response in memory to inject the cookie. Given your performance guidance (streaming over buffering) and that the secured group includes the large GraphQL `/query` endpoint, I plan to **avoid `LoadAndSave`** and instead use scs's lower-level API (`Load`/`Put`/`Commit`/`Destroy`) directly inside the existing `SaveSession`/`AuthViaSession`/`Logout` methods — keeping the current on-demand pattern with zero response buffering and no router middleware changes."}],"stop_reason":"tool_use","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":13557,"cache_read_input_tokens":40245,"output_tokens":6997,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":13557,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":6997,"cache_read_input_tokens":40245,"cache_creation_input_tokens":13557,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":13557},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Cc8Di8N38L43caZ78btGe","type":"assistant","uuid":"d2d9ea9c-68f4-4192-bf43-8fa219a67ae1","timestamp":"2026-06-17T04:44:09.553Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"bce9928c-3f8b-4b95-aa53-56af445a9bbc","version":"2.1.179","gitBranch":"feature/558-replace-gorilla-sessions","slug":"replace-the-gorilla-sessions-package-atomic-metcalfe"}

Database Connection Handle\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/dbConnection.go`\n\nThe database connection is exposed via:\n- **Accessor function:** `GetConnection()` at line 112\n- **Type returned:** `*DBConnection` (struct defined at line 26)\n- **DB accessor:** `GetConnection().DB` returns `*sqlx.DB`\n- **SQLite driver imported:** `github.com/mattn/go-sqlite3` (line 17)\n- **Driver names used in sql.Open():**\n  - Default: `\"sqlite3\"` (line 84)\n  - With debug hooks: `\"sqlite3WithHooks\"` (line 82, registered at line 81)\n\n**Code snippet showing the connection access pattern:**\n```go\n// From line 26-29\ntype DBConnection struct {\n    DB     *sqlx.DB\n    Driver string\n}\n\n// From line 112-118\nfunc GetConnection() *DBConnection {\n    if dbConnInstance == nil {\n        cclog.Fatalf(\"Database connection not initialized!\")\n    }\n    return dbConnInstance\n}\n```\n\nTo access the `*sql.DB` from a `*sqlx.DB`, use the `.DB` field which is a built-in property of sqlx.DB, accessed as: `GetConnection().DB.DB` (the first `.DB` is the DBConnection field, the second `.DB` is the sqlx.DB property).\n\n---\n\n### 2. Database Migration Conventions\n\n**Migration directory:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/migrations/sqlite3/`\n\n**All migration files (11 total):**\n1. `01_init-schema.down.sql` / `01_init-schema.up.sql`\n2. `02_add-index.down.sql` / `02_add-index.up.sql`\n3. `03_add-userprojects.down.sql` / `03_add-userprojects.up.sql`\n4. `04_add-constraints.down.sql` / `04_add-constraints.up.sql`\n5. `05_extend-tags.down.sql` / `05_extend-tags.up.sql`\n6. `06_change-config.down.sql` / `06_change-config.up.sql`\n7. `07_fix-tag-id.down.sql` / `07_fix-tag-id.up.sql`\n8. `08_add-footprint.down.sql` / `08_add-footprint.up.sql`\n9. `09_add-job-cache.down.sql` / `09_add-job-cache.up.sql`\n10. `10_node-table.down.sql` / `10_node-table.up.sql`\n11. `11_optimize-indexes.down.sql` / `11_optimize-indexes.up.sql` (MOST RECENT)\n\n**Naming convention:** `NN_description.{up,down}.sql` where NN is zero-padded number\n\n**Most recent migration (migration 11):**\n\n**11_optimize-indexes.up.sql** (lines 1-111):\n- Drops ~30 overly-specific sorting indexes from earlier migrations\n- Creates 9 new covering/partial indexes optimized for common queries:\n  - 2 covering indexes for grouped stats queries (cluster+user/project+starttime)\n  - 3 covering indexes for status/dashboard queries (with job_state grouping)\n  - 3 partial covering indexes for running jobs only (WHERE job_state = 'running')\n- Ends with `PRAGMA optimize;`\n\n**11_optimize-indexes.down.sql** (lines 1-74):\n- Drops all the new indexes created in migration 11\n- Recreates all the old indexes from migration 09\n- Ends with `PRAGMA optimize;`\n\n**Migration 10 (node-table) up.sql** (lines 1-48):\n- Creates `node` table with id, hostname, cluster, subcluster, meta_data (JSON)\n- Creates `node_state` table with time tracking, resource allocation, health states\n- Creates 9 indexes for both tables including compound indexes on cluster/subcluster\n\n**Schema Version:**\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/migration.go`\n- **Line 28:** `const Version uint = 11`\n- **Lines 23-25 contain version history comments**\n\n**Migration system:**\n- Uses `github.com/golang-migrate/migrate/v4` library (line 26 in go.mod, line 14 in migration.go)\n- Migrations embedded at build time using `//go:embed migrations/*` directive (line 30-31)\n- Applied via `iofs.New()` and `migrate.NewWithInstance()` for embedded filesystem loading\n- Schema versions tracked in SQLite's `schema_migrations` table\n\n---\n\n### 3.

Database Connection Handle\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/dbConnection.go`\n\nThe database connection is exposed via:\n- **Accessor function:** `GetConnection()` at line 112\n- **Type returned:** `*DBConnection` (struct defined at line 26)\n- **DB accessor:** `GetConnection().DB` returns `*sqlx.DB`\n- **SQLite driver imported:** `github.com/mattn/go-sqlite3` (line 17)\n- **Driver names used in sql.Open():**\n  - Default: `\"sqlite3\"` (line 84)\n  - With debug hooks: `\"sqlite3WithHooks\"` (line 82, registered at line 81)\n\n**Code snippet showing the connection access pattern:**\n```go\n// From line 26-29\ntype DBConnection struct {\n    DB     *sqlx.DB\n    Driver string\n}\n\n// From line 112-118\nfunc GetConnection() *DBConnection {\n    if dbConnInstance == nil {\n        cclog.Fatalf(\"Database connection not initialized!\")\n    }\n    return dbConnInstance\n}\n```\n\nTo access the `*sql.DB` from a `*sqlx.DB`, use the `.DB` field which is a built-in property of sqlx.DB, accessed as: `GetConnection().DB.DB` (the first `.DB` is the DBConnection field, the second `.DB` is the sqlx.DB property).\n\n---\n\n### 2. Database Migration Conventions\n\n**Migration directory:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/migrations/sqlite3/`\n\n**All migration files (11 total):**\n1. `01_init-schema.down.sql` / `01_init-schema.up.sql`\n2. `02_add-index.down.sql` / `02_add-index.up.sql`\n3. `03_add-userprojects.down.sql` / `03_add-userprojects.up.sql`\n4. `04_add-constraints.down.sql` / `04_add-constraints.up.sql`\n5. `05_extend-tags.down.sql` / `05_extend-tags.up.sql`\n6. `06_change-config.down.sql` / `06_change-config.up.sql`\n7. `07_fix-tag-id.down.sql` / `07_fix-tag-id.up.sql`\n8. `08_add-footprint.down.sql` / `08_add-footprint.up.sql`\n9. `09_add-job-cache.down.sql` / `09_add-job-cache.up.sql`\n10. `10_node-table.down.sql` / `10_node-table.up.sql`\n11. `11_optimize-indexes.down.sql` / `11_optimize-indexes.up.sql` (MOST RECENT)\n\n**Naming convention:** `NN_description.{up,down}.sql` where NN is zero-padded number\n\n**Most recent migration (migration 11):**\n\n**11_optimize-indexes.up.sql** (lines 1-111):\n- Drops ~30 overly-specific sorting indexes from earlier migrations\n- Creates 9 new covering/partial indexes optimized for common queries:\n  - 2 covering indexes for grouped stats queries (cluster+user/project+starttime)\n  - 3 covering indexes for status/dashboard queries (with job_state grouping)\n  - 3 partial covering indexes for running jobs only (WHERE job_state = 'running')\n- Ends with `PRAGMA optimize;`\n\n**11_optimize-indexes.down.sql** (lines 1-74):\n- Drops all the new indexes created in migration 11\n- Recreates all the old indexes from migration 09\n- Ends with `PRAGMA optimize;`\n\n**Migration 10 (node-table) up.sql** (lines 1-48):\n- Creates `node` table with id, hostname, cluster, subcluster, meta_data (JSON)\n- Creates `node_state` table with time tracking, resource allocation, health states\n- Creates 9 indexes for both tables including compound indexes on cluster/subcluster\n\n**Schema Version:**\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/migration.go`\n- **Line 28:** `const Version uint = 11`\n- **Lines 23-25 contain version history comments**\n\n**Migration system:**\n- Uses `github.com/golang-migrate/migrate/v4` library (line 26 in go.mod, line 14 in migration.go)\n- Migrations embedded at build time using `//go:embed migrations/*` directive (line 30-31)\n- Applied via `iofs.New()` and `migrate.NewWithInstance()` for embedded filesystem loading\n- Schema versions tracked in SQLite's `schema_migrations` table\n\n---\n\n### 3.

We are replacing it with\n`github.com/alexedwards/scs/v2`.\n\nThe packages differ architecturally:\n- **gorilla `CookieStore`** is *stateless* — all session data is encrypted into\n  the cookie itself (signed/encrypted with `SESSION_KEY`). Sessions survive\n  restarts as long as the key is stable.\n- **scs/v2** is *server-side* — only a random token lives in the cookie; the data\n  lives in a store. The cookie needs no encryption key.\n\n**Decisions made:**\n- **Store backend: `sqlite3store`** (persist sessions in the existing SQLite DB).\n  Preserves the current \"stay logged in across restarts\" behavior using the DB\n  they already run. Adds dep `github.com/alexedwards/scs/sqlite3store`.\n- **Remove `SESSION_KEY`** entirely — scs generates secure random tokens, so the\n  key is dead code. Drop the env var, the fatal startup check, and config/doc refs.\n\n**Performance note:** scs's idiomatic `LoadAndSave` middleware buffers the entire\nHTTP response in memory to inject the cookie. The secured route group includes the\nlarge GraphQL `/query` endpoint, and CLAUDE.md mandates streaming over buffering.\nTherefore we will **NOT** use `LoadAndSave`. Instead we keep the existing\non-demand pattern and drive scs's lower-level API (`Load`/`Put`/`Commit`/`Destroy`)\ninside the existing methods, and write the cookie ourselves to preserve the exact\ncurrent cookie semantics (per-request `Secure` flag, name, SameSite, HttpOnly).\nThis means **no router/middleware changes** in `cmd/cc-backend/server.go`.\n\n## Changes\n\n### 1.

We are replacing it with\n`github.com/alexedwards/scs/v2`.\n\nThe packages differ architecturally:\n- **gorilla `CookieStore`** is *stateless* — all session data is encrypted into\n  the cookie itself (signed/encrypted with `SESSION_KEY`). Sessions survive\n  restarts as long as the key is stable.\n- **scs/v2** is *server-side* — only a random token lives in the cookie; the data\n  lives in a store. The cookie needs no encryption key.\n\n**Decisions made:**\n- **Store backend: `sqlite3store`** (persist sessions in the existing SQLite DB).\n  Preserves the current \"stay logged in across restarts\" behavior using the DB\n  they already run. Adds dep `github.com/alexedwards/scs/sqlite3store`.\n- **Remove `SESSION_KEY`** entirely — scs generates secure random tokens, so the\n  key is dead code. Drop the env var, the fatal startup check, and config/doc refs.\n\n**Performance note:** scs's idiomatic `LoadAndSave` middleware buffers the entire\nHTTP response in memory to inject the cookie. The secured route group includes the\nlarge GraphQL `/query` endpoint, and CLAUDE.md mandates streaming over buffering.\nTherefore we will **NOT** use `LoadAndSave`. Instead we keep the existing\non-demand pattern and drive scs's lower-level API (`Load`/`Put`/`Commit`/`Destroy`)\ninside the existing methods, and write the cookie ourselves to preserve the exact\ncurrent cookie semantics (per-request `Secure` flag, name, SameSite, HttpOnly).\nThis means **no router/middleware changes** in `cmd/cc-backend/server.go`.\n\n## Changes\n\n### 1.

We are replacing it with\n`github.com/alexedwards/scs/v2`.\n\nThe packages differ architecturally:\n- **gorilla `CookieStore`** is *stateless* — all session data is encrypted into\n  the cookie itself (signed/encrypted with `SESSION_KEY`). Sessions survive\n  restarts as long as the key is stable.\n- **scs/v2** is *server-side* — only a random token lives in the cookie; the data\n  lives in a store. The cookie needs no encryption key.\n\n**Decisions made:**\n- **Store backend: `sqlite3store`** (persist sessions in the existing SQLite DB).\n  Preserves the current \"stay logged in across restarts\" behavior using the DB\n  they already run. Adds dep `github.com/alexedwards/scs/sqlite3store`.\n- **Remove `SESSION_KEY`** entirely — scs generates secure random tokens, so the\n  key is dead code. Drop the env var, the fatal startup check, and config/doc refs.\n\n**Performance note:** scs's idiomatic `LoadAndSave` middleware buffers the entire\nHTTP response in memory to inject the cookie. The secured route group includes the\nlarge GraphQL `/query` endpoint, and CLAUDE.md mandates streaming over buffering.\nTherefore we will **NOT** use `LoadAndSave`. Instead we keep the existing\non-demand pattern and drive scs's lower-level API (`Load`/`Put`/`Commit`/`Destroy`)\ninside the existing methods, and write the cookie ourselves to preserve the exact\ncurrent cookie semantics (per-request `Secure` flag, name, SameSite, HttpOnly).\nThis means **no router/middleware changes** in `cmd/cc-backend/server.go`.\n\n## Changes\n\n### 1. Dependencies (`go.mod` / `go.sum`)\n- Add `github.com/alexedwards/scs/v2` and `github.com/alexedwards/scs/sqlite3store`.\n- Remove `github.com/gorilla/sessions` (and transitive `gorilla/securecookie` from go.sum) via `go mod tidy`.\n\n### 2. New DB migration — `sessions` table\nCreate migration #12 in `internal/repository/migrations/sqlite3/`:\n- `12_add-sessions-table.up.sql` — the schema sqlite3store expects:\n  ```sql\n  CREATE TABLE sessions (\n      token  TEXT PRIMARY KEY,\n      data   BLOB NOT NULL,\n      expiry REAL NOT NULL\n  );\n  CREATE INDEX sessions_expiry_idx ON sessions(expiry);\n  ```\n- `12_add-sessions-table.down.sql` — `DROP TABLE IF EXISTS sessions;`\n- Bump `Version` to `12` in `internal/repository/migration.go:28` and add a\n  history comment line matching the existing style.\n\n> Note: `repository.Connect()` only *checks* the version; existing installs must\n> run `-migrate-db`. `-init-db` (`cmd/cc-backend/init.go:83`) already calls\n> `MigrateDB`, so fresh installs get the table automatically.\n\n### 3. `internal/auth/auth.go` — the core swap\nReplace the gorilla import with:\n```go\n\"github.com/alexedwards/scs/v2\"\n\"github.com/alexedwards/scs/sqlite3store\"\n\"github.com/ClusterCockpit/cc-backend/internal/repository\"\n\"encoding/gob\"\n```\n(Drop the now-unused `crypto/rand`, `encoding/base64`, `os` imports if nothing\nelse needs them — verify before removing.)\n\n- **Struct** (line 121): replace `sessionStore *sessions.CookieStore` with\n  `sessionManager *scs.SessionManager`.\n\n- **`Init()`** (lines 189–213): delete the entire `SESSION_KEY` block\n  (lines 189–209). Replace with scs setup:\n  ```go\n  gob.Register([]string{}) // needed to gob-encode user.Projects/Roles in session values\n  sm := scs.New()\n  sm.Store = sqlite3store.New(repository.GetConnection().DB.DB)\n  sm.Cookie.Name = \"session\"\n  sm.Cookie.HttpOnly = true\n  sm.Cookie.SameSite = http.SameSiteLaxMode\n  sm.Cookie.Path = \"/\"\n  if d, err := time.ParseDuration(config.Keys.SessionMaxAge); err == nil && d != 0 {\n      sm.Lifetime = d\n      authInstance.SessionMaxAge = d\n  } // else: keep scs default Lifetime; SessionMaxAge stays 0 -> \"session cookie\"\n  authInstance.sessionManager = sm\n  ```\n  Keep the rest of `Init` (authenticator wiring) unchanged.\n\n- **`SaveSession()`** (lines 321–354): rewrite using scs, but build the cookie\n  manually to keep the per-request `Secure` logic identical:\n  ```go\n  ctx, _ := auth.sessionManager.Load(r.Context(), \"\") // new empty session\n  auth.sessionManager.Put(ctx, \"username\", user.Username)\n  auth.sessionManager.Put(ctx, \"projects\", user.Projects)   // []string\n  auth.sessionManager.Put(ctx, \"roles\", user.Roles)         // []string\n  auth.sessionManager.Put(ctx, \"authSource\", int(user.AuthSource))\n  token, expiry, err := auth.sessionManager.Commit(ctx)\n  // ... error handling identical to current ...\n  secure := !(r.TLS == nil && r.Header.Get(\"X-Forwarded-Proto\") != \"https\")\n  // (keep the existing warn logs for the insecure case)\n  maxAge := 0\n  if auth.SessionMaxAge != 0 { maxAge = int(auth.SessionMaxAge.Seconds()) }\n  http.SetCookie(rw, &http.Cookie{\n      Name: \"session\", Value: token, Path: \"/\",\n      Expires: expiry, MaxAge: maxAge,\n      Secure: secure, HttpOnly: true, SameSite: http.SameSiteLaxMode,\n  })\n  ```\n\n- **`AuthViaSession()`** (lines 129–180): rewrite read path. Keep the same\n  validation/return shape (`*schema.User` with `AuthType: schema.AuthSession`):\n  ```go\n  cookie, err := r.Cookie(\"session\")\n  if err != nil { return nil, nil } // no session cookie == not logged in (mirrors session.IsNew)\n  ctx, err := auth.sessionManager.Load(r.Context(), cookie.Value)\n  if err != nil { return nil, err }\n  username := auth.sessionManager.GetString(ctx, \"username\")\n  if username == \"\" { return nil, nil } // unknown/expired token -> treat as no session\n  // projects: auth.sessionManager.Get(ctx,\"projects\").([]string) with ok-check -> default []string\n  // roles: same; if empty -> invalid; destroy + return error (preserve current behavior)\n  // authSource: auth.sessionManager.GetInt(ctx,\"authSource\"), default AuthViaLocalPassword\n  ```\n  For the \"corrupted session\" branches that currently set `MaxAge=-1` and save,\n  call `auth.sessionManager.Destroy(ctx)` and write an expired `session` cookie\n  (same manual-cookie helper) to clear it client-side.\n\n- **`Logout()`** (lines 610–628): rewrite:\n  ```go\n  if cookie, err := r.Cookie(\"session\"); err == nil {\n      ctx, err := auth.sessionManager.Load(r.Context(), cookie.Value)\n      if err == nil { _ = auth.sessionManager.Destroy(ctx) } // removes row from store\n  }\n  http.SetCookie(rw, &http.Cookie{Name:\"session\", Value:\"\", Path:\"/\", MaxAge:-1, HttpOnly:true, SameSite:http.SameSiteLaxMode})\n  onsuccess.ServeHTTP(rw, r)\n  ```\n\n> Consider a small private helper `writeSessionCookie(rw, token, expiry, secure, maxAge)` to avoid duplicating the `http.SetCookie` block across SaveSession / AuthViaSession-clear / Logout.\n\n### 4. Remove SESSION_KEY references elsewhere\n- `.env:8` and `configs/env-template.txt:11` — remove the `SESSION_KEY=` line.\n- `cmd/cc-backend/init.go` — remove `SESSION_KEY` from the embedded `.env` template string it generates.\n- `internal/api/api_test.go` and `internal/api/nats_test.go` — remove the\n  `t.Setenv(\"SESSION_KEY\", ...)` calls (now no-ops; clean them up).\n- Search docs (`*.md`, `docs/`) for `SESSION_KEY` and update any setup instructions.\n\n## Key files\n- `internal/auth/auth.go` — struct, `Init`, `SaveSession`, `AuthViaSession`, `Logout`\n- `internal/repository/migrations/sqlite3/12_add-sessions-table.{up,down}.sql` (new)\n- `internal/repository/migration.go` — `Version` → 12\n- `go.mod` / `go.sum`\n- `.env`, `configs/env-template.txt`, `cmd/cc-backend/init.go`\n- `internal/api/api_test.go`, `internal/api/nats_test.go`\n\n## Verification\n1. `go build ./...` and `make` (frontend unaffected) succeed; `go vet ./...` clean.\n2. `go mod tidy` removes gorilla/sessions; confirm it's gone from go.mod/go.sum.\n3. `go test ./...` passes (esp. `internal/api`, `internal/auth`, `internal/repository`).\n   Tests that build a temp DB must run migrations so the `sessions` table exists.\n4. Fresh DB: `./cc-backend -init-db -add-user demo:admin:demo` then\n   `./cc-backend -server -dev` — DB reaches version 12.\n5. Existing DB: starting `-server` without migrating must fail with the version-12\n   mismatch message; `./cc-backend -migrate-db` then succeeds.\n6. Manual end-to-end in browser:\n   - Log in (local user) → a `session` cookie is set; a row appears in the\n     `sessions` table (`sqlite3 var/job.db 'select token,expiry from sessions;'`).\n   - Authenticated pages/GraphQL `/query` work; verify `/query` responses are not\n     being buffered/regressed.\n   - **Restart the server, reload** → still logged in (durability preserved).\n   - Log out → `sessions` row removed, cookie cleared, redirected to login.\n   - Confirm cookie flags: `HttpOnly`, `SameSite=Lax`, and `Secure` set only over\n     HTTPS/`X-Forwarded-Proto: https` (matches old behavior).\n   - OIDC/JWT-cookie login paths still establish a session (they call `SaveSession`).\n","planFilePath":"/Users/jan/.claude/plans/replace-the-gorilla-sessions-package-atomic-metcalfe.md"},"caller":{"type":"direct"}}],"stop_reason":"tool_use","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":59472,"cache_read_input_tokens":16403,"output_tokens":31,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":59472,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":31,"cache_read_input_tokens":16403,"cache_creation_input_tokens":59472,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":59472},"type":"message"}],"speed":"standard"},"diagnostics":{"cache_miss_reason":{"type":"tools_changed","cache_missed_input_tokens":63022}}},"requestId":"req_011Cc8ELqucSEYpR9NLEctuP","type":"assistant","uuid":"0bd768bd-4483-4777-ac5a-30e1a2788796","timestamp":"2026-06-17T04:51:12.078Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"bce9928c-3f8b-4b95-aa53-56af445a9bbc","version":"2.1.179","gitBranch":"feature/558-replace-gorilla-sessions","slug":"replace-the-gorilla-sessions-package-atomic-metcalfe"}

That eliminates the scary part of `LoadAndSave` (interfering with flushing/hijacking). So correctness is fine and the code is cleaner. Two things to get right:\n\n**1. Buffering — scope the middleware, never apply it at the router root.**\n`LoadAndSave` wraps the response in a buffered writer for *every* request it covers, regardless of whether a session exists. If you `s.router.Use(...)` it globally, you'd buffer the **high-volume JWT data APIs** — `/api`, `/api/metricstore`, `/userapi`, `/frontend` — which return the large metric payloads. That's the real throughput regression, and it's avoidable: those routes are JWT-authenticated and never touch the session.\n\nSo apply `LoadAndSave` only to the routes that read/write the session:\n- `/login`, `/jwt-login`, `/logout` (tiny login-page responses — buffering is free), and\n- the **secured group** (server.go:247 — `/query`, `/search`, template pages).\n\nThat leaves the metric-store/data APIs completely untouched. GraphQL `/query` POST responses do get buffered, but they're fully materialized before write anyway, so the cost is one transient in-memory copy — acceptable.\n\n**2. Per-request `Secure` flag is lost.** This is the one genuine behavior change. Today `SaveSession` sets `Secure=false` per-request when the connection isn't HTTPS. With `LoadAndSave`, `sm.Cookie.Secure` is a single global setting. We'll need to derive it once at startup (e.g. `Secure = HTTPSCertFile != \"\"`, or a small config flag) — meaning a proxy-terminated-TLS deployment would need that flag set. Minor, but worth a note.\n\nWith `LoadAndSave`, the method bodies also get simpler: `SaveSession` becomes `RenewToken(ctx)` + `Put(...)` on the request context (the middleware commits + sets the cookie); `AuthViaSession` reads via `GetString(ctx, ...)`; `Logout` calls `Destroy(ctx)`. No manual cookie handling.\n\nWant me to update the plan to the `LoadAndSave` approach (scoped to login/logout + secured group, with the global `Secure` setting derived from config)? Once you confirm I'll revise and re-present."}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":131,"cache_creation_input_tokens":3409,"cache_read_input_tokens":76014,"output_tokens":1044,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":3409,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":131,"output_tokens":1044,"cache_read_input_tokens":76014,"cache_creation_input_tokens":3409,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":3409},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Cc8EwT98Piw1UwzGJck3g","type":"assistant","uuid":"45cc5cf1-caee-4cc8-b28f-d7f95266bef1","timestamp":"2026-06-17T04:59:21.616Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"bce9928c-3f8b-4b95-aa53-56af445a9bbc","version":"2.1.179","gitBranch":"feature/558-replace-gorilla-sessions","slug":"replace-the-gorilla-sessions-package-atomic-metcalfe"}

**Non-GraphQL Requests:**\n   - Use **session cookies** (credentials: same-origin by default in fetch API)\n   - No explicit Authorization header is set in fetch calls\n   - Form submissions rely on browser's automatic cookie handling\n   - JWT is only used for GraphQL queries\n\n3. **JWT Token Source:**\n   - Obtained via `/frontend/jwt/?username={username}` endpoint\n   - Only used for GraphQL client initialization\n   - Users with API authority can generate/copy JWT for API access\n\n---\n\n### TASK 5: Deduplicated List of All Backend Paths Called by Web UI\n\n#### By Path

Submissions\n\n**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/web/templates/login.tmpl:31`\n\n| File | Line | Method | Path | Purpose |\n|------|------|--------|------|---------|\n| login.tmpl | 31 | POST | `/login` | User login form submission |\n\n---\n\n### TASK 4: Authentication Method\n\n**Authentication Approach:**\n\n1. **GraphQL Requests (`/query`):** \n   - Uses optional JWT Bearer token in Authorization header\n   - Configuration at `/Users/jan/prg/ClusterCockpit/cc-backend/web/frontend/src/generic/utils.js:31`\n   - `Authorization: Bearer ${jwt}` (only if JWT exists)\n\n2. **Non-GraphQL Requests:**\n   - Use **session cookies** (credentials: same-origin by default in fetch API)\n   - No explicit Authorization header is set in fetch calls\n   - Form submissions rely on browser's automatic cookie handling\n   - JWT is only used for GraphQL queries\n\n3. **JWT Token Source:**\n   - Obtained via `/frontend/jwt/?username={username}` endpoint\n   - Only used for GraphQL client initialization\n   - Users with API authority can generate/copy JWT for API access\n\n---\n\n### TASK 5: Deduplicated List of All Backend Paths Called by Web UI\n\n#### By Path Prefix:\n\n**`/query` (GraphQL)**\n- `POST /query` - GraphQL endpoint (primary data fetching)\n\n**`/frontend/*`**\n- `GET /frontend/logs/?since=&lines=&level=&search=` - Fetch logs\n- `POST /frontend/configuration/` - Update user configuration/preferences (key, value pairs)\n- `GET /frontend/jwt/?username=` - Get JWT token for user\n\n**`/config/*`**\n- `GET /config/users/?via-ldap=false&not-just-user=true` - List users\n- `GET /config/roles/` - List roles\n- `POST /config/users/` - Create user\n- `DELETE /config/users/` - Delete user\n- `POST /config/user/{username}` - Modify user (add/remove role, add/remove project)\n- `GET /config/taggers/` - List taggers\n- `POST /config/taggers/run/` - Run tagger\n- `POST /config/notice/` - Update notice content\n\n**`/monitoring/*` (Page Navigation Links - NOT HTTP requests, client-side routing)**\n- `/monitoring/jobs/` - Jobs list page\n- `/monitoring/job/{jobId}` - Single job detail page\n- `/monitoring/user/{username}` - User detail page\n- `/monitoring/users/` - Users list page\n- `/monitoring/projects/` - Projects list page\n- `/monitoring/tags/` - Tags list page\n- `/monitoring/node/{cluster}/{hostname}` - Node detail page\n- `/monitoring/systems/` - Systems/nodes overview page\n- `/monitoring/analysis/` - Analysis page\n- `/monitoring/status/` - Status/dashboard page\n- `/monitoring/dashboard/{cluster}` - Cluster dashboard\n- `/monitoring/logs` - Logs page\n\n**Authentication & Session**\n- `POST /login` - Login form\n- `POST /logout` - Logout\n- `GET /oidc-login` - OpenID Connect login (referenced in template)\n\n**Other Page Routes**\n- `GET /` - Home page\n- `GET /config` - Configuration page\n- `GET /search` - Search results page\n- `POST /search` - Search submission\n\n---\n\n## Summary Table: Complete Backend Endpoint Inventory\n\n| Endpoint | Method | Used By | Auth Type

Here is the thorough analysis.\n\n## Frontend ↔ Backend endpoint analysis\n\n### How the web UI authenticates\n- **Non-GraphQL `fetch()` calls** (config, frontend, search, logout) send no `Authorization` header → they ride the **session cookie** (same-origin).\n- **GraphQL `/query`** (urql client, `utils.js:28`): it *would* attach `Authorization: Bearer <jwt>` **only if** a `jwt` value exists in the `cc-config` context (`utils.js:24-26`). I traced where that comes from: `cc-config` is the Go-injected `{{ .Config }}` = the user's UI config (`GetUIConfig`), and **nothing anywhere sets a `\"jwt\"` key** in it, and there is no `setContext(\"jwt\", …)` in the frontend. So `jwt` is always `null` → **the web UI's GraphQL calls also use the session cookie.** The Bearer-token branch is **dormant/dead code.**\n\n### Endpoint classification (what's actually wired today)\n\n| Route group | Middleware | Auth | Used by | Conforms? |\n|---|---|---|---|---|\n| `/query` (GraphQL) | `Auth()` | session, JWT fallback | **Web UI** (session) + external clients (JWT) | ✅ |\n| `/search`, `/`, `/config`, `/monitoring/*` pages | `Auth()` | session (JWT fallback) | Web UI | ✅ |\n| `/frontend/*` (logs, jwt, configuration) | `AuthFrontendAPI()` | **session only** | Web UI | ✅ |\n| `/config/*` (admin: users, roles, taggers, notice) | `AuthConfigAPI()` | **session only** | Web UI (admin) | ✅ |\n| `/login`, `/jwt-login`, `/logout` | public / session write | session | Web UI | ✅ |\n| `/api/*` (jobs, users, clusters, nodestate…) | `AuthAPI()` | **JWT only** | External | ✅ |\n| `/api/metricstore` (write/free/debug/healthcheck) | `AuthMetricStoreAPI()` | **JWT only** | External (cc-metric-store etc.) | ✅ |\n| `/userapi/*` (jobs, metrics) | `AuthUserAPI()` | **JWT only** | External | ✅ |\n\n### Verdict\n**The codebase already implements your desired model.** Web-UI traffic is session-authenticated; only the external machine-to-machine APIs (`/api`, `/userapi`, `/api/metricstore`) require JWT. The one purpose-built bridge is `/frontend/jwt/` — a **session-authenticated** endpoint that mints a JWT for a logged-in user to copy and use against the *external* JWT APIs (the \"Gen. JWT\" button in `UserOptions.svelte`). That's exactly the right boundary.\n\nTwo things stand out, neither breaking the model:\n1. **`/query` is dual-auth** (session *and* JWT). This is correct and intentional — the UI uses the session, external GraphQL clients use JWT. It fits \"external uses JWT.\"\n2. **Dead Bearer code in `utils.js:24-31`** — inert today. Could be removed for clarity, but harmless.\n\n### Why this matters for the scs migration (LoadAndSave scoping)\nThe session middleware must wrap **exactly the session-authenticated routes**, and must **not** wrap the JWT-only groups — which is also where the large metric/job payloads live (so buffering stays off the hot path):\n\n- **Wrap with `LoadAndSave`:** secured group (`/query`, `/search`, pages), `/config/*` group, `/frontend/*` group, and the `/login` `/jwt-login` `/logout` handlers.\n- **Do NOT wrap:** `/api/*`, `/api/metricstore`, `/userapi/*`, static files (`/*`, `/img/*`), `/imprint`, `/privacy`.\n\nThe only large session-route that `LoadAndSave` will buffer is GraphQL `/query`. That's the residual cost of the LoadAndSave approach (the JWT data APIs are excluded, so the heaviest payloads are unaffected).\n\nLet me record this in the plan and confirm one design choice with you."}],"stop_reason":"tool_use","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":620,"cache_read_input_tokens":105905,"output_tokens":5018,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":620,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":5018,"cache_read_input_tokens":105905,"cache_creation_input_tokens":620,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":620},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Cc8FkdRZhe1YHUWNsFoem","type":"assistant","uuid":"727fe7fb-aef0-4ff5-a9e1-25ebf6e24dc0","timestamp":"2026-06-17T05:10:39.040Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"bce9928c-3f8b-4b95-aa53-56af445a9bbc","version":"2.1.179","gitBranch":"feature/558-replace-gorilla-sessions","slug":"replace-the-gorilla-sessions-package-atomic-metcalfe"}

We are replacing it with\n`github.com/alexedwards/scs/v2`, backed by the existing SQLite DB.\n\nThe packages differ architecturally:\n- **gorilla `CookieStore`** is *stateless* — all data is encrypted into the cookie\n  (signed with `SESSION_KEY`); sessions survive restarts while the key is stable.\n- **scs/v2** is *server-side* — only a random token lives in the cookie; data lives\n  in a store. No encryption key needed.\n\n**Decisions made:**\n- **Store: `sqlite3store`** in the existing SQLite DB (preserves \"stay logged in\n  across restarts\"). Adds dep `github.com/alexedwards/scs/sqlite3store`.\n- **Remove `SESSION_KEY`** — dead code with server-side tokens.\n- **Use scs's idiomatic `LoadAndSave` middleware** (the clean approach), scoped to\n  only the session-authenticated route groups (see endpoint analysis below).\n- **`/query` stays dual-auth** (session for the web UI, JWT for external GraphQL\n  clients) — no change to `Auth()`.\n- **Frontend cleanup:** remove the dormant Bearer-JWT branch in the urql client.\n\n### Endpoint analysis (frontend=session, external=JWT)\n\nThe codebase already matches this model. Verified: the web UI's GraphQL client only\nattaches `Authorization: Bearer` if a `jwt` exists in the `cc-config` context\n(`web/frontend/src/generic/utils.js:24-31`), but nothing ever injects one — so the\nUI authenticates `/query` via the **session cookie**; the Bearer branch is dead.\n\n| Route group | Auth today | Caller | LoadAndSave? |\n|---|---|---|---|\n| `/query`, `/search`, pages `/`,`/config`,`/monitoring/*` (`Auth()`) | session (+JWT fallback) | web UI (+ external GraphQL) | **YES** |\n| `/frontend/*` logs,jwt,configuration (`AuthFrontendAPI`) | session only | web UI | **YES** |\n| `/config/*` admin (`AuthConfigAPI`) | session only | web UI (admin) | **YES** |\n| `/login`, `/jwt-login`, `/logout` | session write | web UI | **YES** |\n| `/api/*` (`AuthAPI`) | JWT only | external | **NO** |\n| `/api/metricstore` (`AuthMetricStoreAPI`) | JWT only | external | **NO** |\n| `/userapi/*` (`AuthUserAPI`) | JWT only | external | **NO** |\n| static `/*`, `/img/*`, `/imprint`, `/privacy` | none | browser | **NO** |\n\n`LoadAndSave` buffers the full response to inject the cookie. Scoping it to the\nsession groups keeps it **off the JWT data APIs** (`/api`, `/userapi`,\n`/api/metricstore`) where the large metric/job payloads live. The only large\nsession-route it buffers is GraphQL `/query` — the accepted residual cost.\n`/frontend/jwt/` (mints a JWT for a logged-in user to use against the external JWT\nAPIs) is the intended session→JWT bridge and stays as-is.\n\n## Changes\n\n### 1. Dependencies (`go.mod` / `go.sum`)\n- Add `github.com/alexedwards/scs/v2` and `github.com/alexedwards/scs/sqlite3store`.\n- Remove `github.com/gorilla/sessions` (+ transitive `gorilla/securecookie`) via `go mod tidy`.\n\n### 2. New DB migration — `sessions` table\n`internal/repository/migrations/sqlite3/12_add-sessions-table.{up,down}.sql`:\n```sql\n-- up\nCREATE TABLE sessions (\n    token  TEXT PRIMARY KEY,\n    data   BLOB NOT NULL,\n    expiry REAL NOT NULL\n);\nCREATE INDEX sessions_expiry_idx ON sessions(expiry);\n-- down\nDROP TABLE IF EXISTS sessions;\n```\nBump `Version` to `12` in `internal/repository/migration.go:28` + add a history\ncomment. `Connect()` only *checks* the version, so existing installs run\n`-migrate-db`; `-init-db` (`cmd/cc-backend/init.go:83`) already migrates fresh DBs.\n\n### 3. `internal/auth/auth.go` — the core swap\nReplace the gorilla import with `github.com/alexedwards/scs/v2`,\n`github.com/alexedwards/scs/sqlite3store`, `encoding/gob`,\n`.../internal/repository`.

We are replacing it with\n`github.com/alexedwards/scs/v2`.\n\nThe packages differ architecturally:\n- **gorilla `CookieStore`** is *stateless* — all session data is encrypted into\n  the cookie itself (signed/encrypted with `SESSION_KEY`). Sessions survive\n  restarts as long as the key is stable.\n- **scs/v2** is *server-side* — only a random token lives in the cookie; the data\n  lives in a store. The cookie needs no encryption key.\n\n**Decisions made:**\n- **Store backend: `sqlite3store`** (persist sessions in the existing SQLite DB).\n  Preserves the current \"stay logged in across restarts\" behavior using the DB\n  they already run. Adds dep `github.com/alexedwards/scs/sqlite3store`.\n- **Remove `SESSION_KEY`** entirely — scs generates secure random tokens, so the\n  key is dead code. Drop the env var, the fatal startup check, and config/doc refs.\n\n**Performance note:** scs's idiomatic `LoadAndSave` middleware buffers the entire\nHTTP response in memory to inject the cookie. The secured route group includes the\nlarge GraphQL `/query` endpoint, and CLAUDE.md mandates streaming over buffering.\nTherefore we will **NOT** use `LoadAndSave`. Instead we keep the existing\non-demand pattern and drive scs's lower-level API (`Load`/`Put`/`Commit`/`Destroy`)\ninside the existing methods, and write the cookie ourselves to preserve the exact\ncurrent cookie semantics (per-request `Secure` flag, name, SameSite, HttpOnly).\nThis means **no router/middleware changes** in `cmd/cc-backend/server.go`.\n\n## Changes\n\n### 1. Dependencies (`go.mod` / `go.sum`)\n- Add `github.com/alexedwards/scs/v2` and `github.com/alexedwards/scs/sqlite3store`.\n- Remove `github.com/gorilla/sessions` (and transitive `gorilla/securecookie` from go.sum) via `go mod tidy`.\n\n### 2. New DB migration — `sessions` table\nCreate migration #12 in `internal/repository/migrations/sqlite3/`:\n- `12_add-sessions-table.up.sql` — the schema sqlite3store expects:\n  ```sql\n  CREATE TABLE sessions (\n      token  TEXT PRIMARY KEY,\n      data   BLOB NOT NULL,\n      expiry REAL NOT NULL\n  );\n  CREATE INDEX sessions_expiry_idx ON sessions(expiry);\n  ```\n- `12_add-sessions-table.down.sql` — `DROP TABLE IF EXISTS sessions;`\n- Bump `Version` to `12` in `internal/repository/migration.go:28` and add a\n  history comment line matching the existing style.\n\n> Note: `repository.Connect()` only *checks* the version; existing installs must\n> run `-migrate-db`. `-init-db` (`cmd/cc-backend/init.go:83`) already calls\n> `MigrateDB`, so fresh installs get the table automatically.\n\n### 3. `internal/auth/auth.go` — the core swap\nReplace the gorilla import with:\n```go\n\"github.com/alexedwards/scs/v2\"\n\"github.com/alexedwards/scs/sqlite3store\"\n\"github.com/ClusterCockpit/cc-backend/internal/repository\"\n\"encoding/gob\"\n```\n(Drop the now-unused `crypto/rand`, `encoding/base64`, `os` imports if nothing\nelse needs them — verify before removing.)\n\n- **Struct** (line 121): replace `sessionStore *sessions.CookieStore` with\n  `sessionManager *scs.SessionManager`.\n\n- **`Init()`** (lines 189–213): delete the entire `SESSION_KEY` block\n  (lines 189–209).

Keep the same\n  validation/return shape (`*schema.User` with `AuthType: schema.AuthSession`):\n  ```go\n  cookie, err := r.Cookie(\"session\")\n  if err != nil { return nil, nil } // no session cookie == not logged in (mirrors session.IsNew)\n  ctx, err := auth.sessionManager.Load(r.Context(), cookie.Value)\n  if err != nil { return nil, err }\n  username := auth.sessionManager.GetString(ctx, \"username\")\n  if username == \"\" { return nil, nil } // unknown/expired token -> treat as no session\n  // projects: auth.sessionManager.Get(ctx,\"projects\").([]string) with ok-check -> default []string\n  // roles: same; if empty -> invalid; destroy + return error (preserve current behavior)\n  // authSource: auth.sessionManager.GetInt(ctx,\"authSource\"), default AuthViaLocalPassword\n  ```\n  For the \"corrupted session\" branches that currently set `MaxAge=-1` and save,\n  call `auth.sessionManager.Destroy(ctx)` and write an expired `session` cookie\n  (same manual-cookie helper) to clear it client-side.\n\n- **`Logout()`** (lines 610–628): rewrite:\n  ```go\n  if cookie, err := r.Cookie(\"session\"); err == nil {\n      ctx, err := auth.sessionManager.Load(r.Context(), cookie.Value)\n      if err == nil { _ = auth.sessionManager.Destroy(ctx) } // removes row from store\n  }\n  http.SetCookie(rw, &http.Cookie{Name:\"session\", Value:\"\", Path:\"/\", MaxAge:-1, HttpOnly:true, SameSite:http.SameSiteLaxMode})\n  onsuccess.ServeHTTP(rw, r)\n  ```\n\n> Consider a small private helper `writeSessionCookie(rw, token, expiry, secure, maxAge)` to avoid duplicating the `http.SetCookie` block across SaveSession / AuthViaSession-clear / Logout.\n\n### 4.

We are replacing it with\n`github.com/alexedwards/scs/v2`, backed by the existing SQLite DB.\n\nThe packages differ architecturally:\n- **gorilla `CookieStore`** is *stateless* — all data is encrypted into the cookie\n  (signed with `SESSION_KEY`); sessions survive restarts while the key is stable.\n- **scs/v2** is *server-side* — only a random token lives in the cookie; data lives\n  in a store. No encryption key needed.\n\n**Decisions made:**\n- **Store: `sqlite3store`** in the existing SQLite DB (preserves \"stay logged in\n  across restarts\"). Adds dep `github.com/alexedwards/scs/sqlite3store`.\n- **Remove `SESSION_KEY`** — dead code with server-side tokens.\n- **Use scs's idiomatic `LoadAndSave` middleware** (the clean approach), scoped to\n  only the session-authenticated route groups (see endpoint analysis below).\n- **`/query` stays dual-auth** (session for the web UI, JWT for external GraphQL\n  clients) — no change to `Auth()`.\n- **Frontend cleanup:** remove the dormant Bearer-JWT branch in the urql client.\n\n### Endpoint analysis (frontend=session, external=JWT)\n\nThe codebase already matches this model. Verified: the web UI's GraphQL client only\nattaches `Authorization: Bearer` if a `jwt` exists in the `cc-config` context\n(`web/frontend/src/generic/utils.js:24-31`), but nothing ever injects one — so the\nUI authenticates `/query` via the **session cookie**; the Bearer branch is dead.\n\n| Route group | Auth today | Caller | LoadAndSave? |\n|---|---|---|---|\n| `/query`, `/search`, pages `/`,`/config`,`/monitoring/*` (`Auth()`) | session (+JWT fallback) | web UI (+ external GraphQL) | **YES** |\n| `/frontend/*` logs,jwt,configuration (`AuthFrontendAPI`) | session only | web UI | **YES** |\n| `/config/*` admin (`AuthConfigAPI`) | session only | web UI (admin) | **YES** |\n| `/login`, `/jwt-login`, `/logout` | session write | web UI | **YES** |\n| `/api/*` (`AuthAPI`) | JWT only | external | **NO** |\n| `/api/metricstore` (`AuthMetricStoreAPI`) | JWT only | external | **NO** |\n| `/userapi/*` (`AuthUserAPI`) | JWT only | external | **NO** |\n| static `/*`, `/img/*`, `/imprint`, `/privacy` | none | browser | **NO** |\n\n`LoadAndSave` buffers the full response to inject the cookie. Scoping it to the\nsession groups keeps it **off the JWT data APIs** (`/api`, `/userapi`,\n`/api/metricstore`) where the large metric/job payloads live. The only large\nsession-route it buffers is GraphQL `/query` — the accepted residual cost.\n`/frontend/jwt/` (mints a JWT for a logged-in user to use against the external JWT\nAPIs) is the intended session→JWT bridge and stays as-is.\n\n## Changes\n\n### 1. Dependencies (`go.mod` / `go.sum`)\n- Add `github.com/alexedwards/scs/v2` and `github.com/alexedwards/scs/sqlite3store`.\n- Remove `github.com/gorilla/sessions` (+ transitive `gorilla/securecookie`) via `go mod tidy`.\n\n### 2. New DB migration — `sessions` table\n`internal/repository/migrations/sqlite3/12_add-sessions-table.{up,down}.sql`:\n```sql\n-- up\nCREATE TABLE sessions (\n    token  TEXT PRIMARY KEY,\n    data   BLOB NOT NULL,\n    expiry REAL NOT NULL\n);\nCREATE INDEX sessions_expiry_idx ON sessions(expiry);\n-- down\nDROP TABLE IF EXISTS sessions;\n```\nBump `Version` to `12` in `internal/repository/migration.go:28` + add a history\ncomment. `Connect()` only *checks* the version, so existing installs run\n`-migrate-db`; `-init-db` (`cmd/cc-backend/init.go:83`) already migrates fresh DBs.\n\n### 3. `internal/auth/auth.go` — the core swap\nReplace the gorilla import with `github.com/alexedwards/scs/v2`,\n`github.com/alexedwards/scs/sqlite3store`, `encoding/gob`,\n`.../internal/repository`. Drop now-unused `crypto/rand`, `encoding/base64`, `os`\n(verify before removing).\n\n- **Struct** (line 121): `sessionStore *sessions.CookieStore` → `sessionManager *scs.SessionManager`.\n- **Add accessor** so the router can install the middleware:\n  `func (auth *Authentication) SessionManager() *scs.SessionManager { return auth.sessionManager }`\n- **`Init()`** (lines 189–213): delete the whole `SESSION_KEY` block; replace with:\n  ```go\n  gob.Register([]string{}) // user.Projects / user.Roles are []string in session values\n  sm := scs.New()\n  sm.Store = sqlite3store.New(repository.GetConnection().DB.DB)\n  sm.Cookie.Name = \"session\"\n  sm.Cookie.Path = \"/\"\n  sm.Cookie.HttpOnly = true\n  sm.Cookie.SameSite = http.SameSiteLaxMode\n  sm.Cookie.Secure = config.Keys.HTTPSCertFile != \"\" // see note\n  if d, err := time.ParseDuration(config.Keys.SessionMaxAge); err == nil && d != 0 {\n      sm.Lifetime = d\n      authInstance.SessionMaxAge = d\n  } // else keep a long default lifetime (config says 0 == \"no expiry\")\n  authInstance.sessionManager = sm\n  ```\n  > Note on `Secure`: scs sets the flag globally (no per-request option like the old\n  > code). Deriving it from `HTTPSCertFile` is actually *stricter* than today — the\n  > current code only ever sets `Secure=false` and never `true` (gorilla's default is\n  > `false`), so the flag is effectively never set now. Reverse-proxy-TLS deployments\n  > that want `Secure` can get a follow-up config flag.\n- **`SaveSession(rw, r, user)`** (lines 321–354): the login routes are wrapped by\n  `LoadAndSave`, so operate on the request context; the middleware commits + writes\n  the cookie:\n  ```go\n  if err := auth.sessionManager.RenewToken(r.Context()); err != nil { // session-fixation guard\n      cclog.Errorf(\"session renew failed: %s\", err.Error()); http.Error(...); return err\n  }\n  auth.sessionManager.Put(r.Context(), \"username\", user.Username)\n  auth.sessionManager.Put(r.Context(), \"projects\", user.Projects)\n  auth.sessionManager.Put(r.Context(), \"roles\", user.Roles)\n  auth.sessionManager.Put(r.Context(), \"authSource\", int(user.AuthSource))\n  return nil\n  ```\n- **`AuthViaSession(rw, r)`** (lines 129–180): read from the context loaded by the\n  middleware; keep the same `*schema.User`/error return shape:\n  ```go\n  if !auth.sessionManager.Exists(r.Context(), \"username\") { return nil, nil } // mirrors session.IsNew\n  username := auth.sessionManager.GetString(r.Context(), \"username\")\n  if username == \"\" { /* corrupted */ _ = auth.sessionManager.Destroy(r.Context()); return nil, errors.New(\"invalid session data\") }\n  projects, _ := auth.sessionManager.Get(r.Context(), \"projects\").([]string) // default []string\n  roles, _ := auth.sessionManager.Get(r.Context(), \"roles\").([]string)\n  if len(roles) == 0 { _ = auth.sessionManager.Destroy(r.Context()); return nil, errors.New(\"invalid session data\") }\n  authSource := auth.sessionManager.GetInt(r.Context(), \"authSource\") // 0 default == AuthViaLocalPassword\n  return &schema.User{Username: username, Projects: projects, Roles: roles, AuthType: schema.AuthSession, AuthSource: schema.AuthSource(authSource)}, nil\n  ```\n- **`Logout()`** (lines 610–628): `_ = auth.sessionManager.Destroy(r.Context())` then\n  call `onsuccess` (middleware clears the cookie). Drop all gorilla calls.\n\n### 4. `cmd/cc-backend/server.go` — install LoadAndSave (scoped)\nGrab the manager once: `sm := authHandle.SessionManager()`. Wrap **only** the\nsession groups (all inside the existing `if !config.Keys.DisableAuthentication`\nguards so disabled-auth keeps no sessions):\n- `/login`, `/jwt-login`, `/logout`: wrap each handler, e.g.\n  `s.router.Post(\"/login\", sm.LoadAndSave(authHandle.Login(loginFailureHandler)).ServeHTTP)`.\n- Secured group (line 247): add `secured.Use(sm.LoadAndSave)` **before** the\n  `authHandle.Auth` middleware (LoadAndSave must load the session into ctx first).\n- Config group (line 310): add `configapi.Use(sm.LoadAndSave)` before `AuthConfigAPI`.\n- Frontend group (line 320): add `frontendapi.Use(sm.LoadAndSave)` before `AuthFrontendAPI`.\n- **Leave `/api`, `/api/metricstore`, `/userapi`, static files unwrapped.**\n\n### 5. Frontend cleanup — `web/frontend/src/generic/utils.js`\nIn `init()` remove the dormant Bearer path: delete the `jwt` lookup (lines 24–26)\nand the conditional `fetchOptions` Authorization header (line 31); construct the\nurql `Client` with just `url` + `exchanges`. **Keep** the user-facing\n`/frontend/jwt/` fetch at line ~583 (the \"Gen. JWT\" copy feature for external API\nuse). Rebuild with `make frontend`.\n\n### 6. Remove SESSION_KEY everywhere\n- `.env:8`, `configs/env-template.txt:11`: delete the `SESSION_KEY=` line.\n- `cmd/cc-backend/init.go`: remove `SESSION_KEY` from the embedded `.env` template.\n- `internal/api/api_test.go`, `internal/api/nats_test.go`: remove the\n  `t.Setenv(\"SESSION_KEY\", ...)` calls.\n- Update any `*.md`/docs referencing `SESSION_KEY`.\n\n## Key files\n- `internal/auth/auth.go` — struct, `SessionManager()`, `Init`, `SaveSession`, `AuthViaSession`, `Logout`\n- `cmd/cc-backend/server.go` — scoped `LoadAndSave` wiring\n- `internal/repository/migrations/sqlite3/12_add-sessions-table.{up,down}.sql` (new) + `migration.go` (`Version` → 12)\n- `web/frontend/src/generic/utils.js` — drop dead Bearer branch\n- `go.mod`/`go.sum`, `.env`, `configs/env-template.txt`, `cmd/cc-backend/init.go`, `internal/api/{api,nats}_test.go`\n\n## Verification\n1. `go build ./...`, `make` (incl. `make frontend`), `go vet ./...` clean.\n2. `go mod tidy` removes gorilla/sessions; confirm gone from go.mod/go.sum.\n3. `go test ./...` passes (esp. `internal/api`, `internal/auth`, `internal/repository`).\n4. Fresh DB: `./cc-backend -init-db -add-user demo:admin:demo` then `-server -dev` → DB at version 12.\n5. Existing DB: `-server` without migrating fails with the version-12 message; `-migrate-db` then succeeds.\n6. Manual end-to-end (browser, `-dev`):\n   - Log in → `session` cookie set; a row appears: `sqlite3 var/job.db 'select token,expiry from sessions;'`.\n   - Web UI works: dashboard/job views (GraphQL `/query` via session), `/search`,\n     `/config/*` admin actions, `/frontend/configuration/` saves, `/frontend/logs/`.\n   - **Restart server, reload** → still logged in (durability preserved).\n   - Log out → `sessions` row removed, cookie cleared, back to login page.\n   - Cookie flags: `HttpOnly`, `SameSite=Lax` (and `Secure` when serving HTTPS).\n   - External JWT still works: `/query` with a Bearer token, and `/api/*` /\n     `/userapi/*` endpoints (these are NOT session-wrapped) — confirm large\n     `/api/jobs/metrics/{id}` responses are not buffered/regressed.\n   - OIDC / JWT-cookie login still establishes a session (they call `SaveSession`).\n","planFilePath":"/Users/jan/.claude/plans/replace-the-gorilla-sessions-package-atomic-metcalfe.md"},"caller":{"type":"direct"}}],"stop_reason":"tool_use","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":8576,"cache_read_input_tokens":111832,"output_tokens":152,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":8576,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":152,"cache_read_input_tokens":111832,"cache_creation_input_tokens":8576,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":8576},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Cc8GGJQQXWhTTKs3yxf33","type":"assistant","uuid":"422cfff1-a5f6-4391-a009-6f87d44ab3f1","timestamp":"2026-06-17T05:16:26.369Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"bce9928c-3f8b-4b95-aa53-56af445a9bbc","version":"2.1.179","gitBranch":"feature/558-replace-gorilla-sessions","slug":"replace-the-gorilla-sessions-package-atomic-metcalfe"}

Pure overhead vs. streaming.\n- **Allocations / GC**: each large query allocates and then discards a big buffer — exactly the allocation churn CLAUDE.md says to avoid on the hot path.\n- **Latency**: marginal. gqlgen's `transport.POST` already marshals the whole response before writing, so buffering adds a memcopy, not a re-architecture of TTFB.\n\nSo: not a showstopper at small scale, but it directly contradicts the \"streaming over buffering, minimize allocations\" directive — and `/query` is the single hottest session-authenticated route.\n\n## The fix — don't buffer the read paths\nThe key insight: **the session is only ever *written* at login/logout.** Every other session route (`/query`, `/search`, pages, `/config/*`, `/frontend/*`) only *reads* it to authenticate. Buffering is only needed when you write a cookie. So:\n\n- **login / jwt-login / logout** (session written, tiny login-page responses): use `LoadAndSave` — buffering is free here.\n- **secured / config / frontend** (session read-only): use a tiny **non-buffering** middleware that just loads the session into the request context (`sm.Load`, no commit, no cookie write, no `ResponseWriter` wrap). `AuthViaSession` then reads from context exactly as planned.\n\n```go\nfunc loadSession(sm *scs.SessionManager, next http.Handler) http.Handler {\n    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {\n        token := \"\"\n        if c, err := r.Cookie(sm.Cookie.Name); err == nil { token = c.Value }\n        ctx, err := sm.Load(r.Context(), token) // expiry enforced here\n        if err != nil { http.Error(w, \"session load failed\", 500); return }\n        next.ServeHTTP(w, r.WithContext(ctx)) // no commit, no buffering -> /query streams\n    })\n}\n```\n\nThis keeps the clean middleware structure you wanted **and** leaves `/query` fully streaming. The only tradeoff: a \"corrupted session\" detected on a read path is cleared best-effort via a manual expired-cookie write instead of an auto-commit (trivial; we don't use idle-timeout, and absolute expiry is enforced at `Load`).\n\nWhich approach do you want?"}],"stop_reason":"tool_use","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":272,"cache_read_input_tokens":120408,"output_tokens":4397,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":272,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":4397,"cache_read_input_tokens":120408,"cache_creation_input_tokens":272,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":272},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Cc8GT8ZdDXUu8YsJDWQfs","type":"assistant","uuid":"f5c76c9d-4216-42de-8202-5ffde3a02232","timestamp":"2026-06-17T05:19:42.201Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"bce9928c-3f8b-4b95-aa53-56af445a9bbc","version":"2.1.179","gitBranch":"feature/558-replace-gorilla-sessions","slug":"replace-the-gorilla-sessions-package-atomic-metcalfe"}

We are replacing it with\n`github.com/alexedwards/scs/v2`, backed by the existing SQLite DB.\n\nThe packages differ architecturally:\n- **gorilla `CookieStore`** is *stateless* — all data is encrypted into the cookie\n  (signed with `SESSION_KEY`); sessions survive restarts while the key is stable.\n- **scs/v2** is *server-side* — only a random token lives in the cookie; data lives\n  in a store. No encryption key needed.\n\n**Decisions made:**\n- **Store: `sqlite3store`** in the existing SQLite DB (preserves \"stay logged in\n  across restarts\").

Verified: the web UI's GraphQL client only\nattaches `Authorization: Bearer` if a `jwt` exists in the `cc-config` context\n(`web/frontend/src/generic/utils.js:24-31`), but nothing ever injects one — so the\nUI authenticates `/query` via the **session cookie**; the Bearer branch is dead.\n\n| Route group | Auth today | Caller | LoadAndSave? |\n|---|---|---|---|\n| `/query`, `/search`, pages `/`,`/config`,`/monitoring/*` (`Auth()`) | session (+JWT fallback) | web UI (+ external GraphQL) | **YES** |\n| `/frontend/*` logs,jwt,configuration (`AuthFrontendAPI`) | session only | web UI | **YES** |\n| `/config/*` admin (`AuthConfigAPI`) | session only | web UI (admin) | **YES** |\n| `/login`, `/jwt-login`, `/logout` | session write | web UI | **YES** |\n| `/api/*` (`AuthAPI`) | JWT only | external | **NO** |\n| `/api/metricstore` (`AuthMetricStoreAPI`) | JWT only | external | **NO** |\n| `/userapi/*` (`AuthUserAPI`) | JWT only | external | **NO** |\n| static `/*`, `/img/*`, `/imprint`, `/privacy` | none | browser | **NO** |\n\n`LoadAndSave` buffers the full response to inject the cookie, so it is used **only**\non the tiny login/logout write-paths.

Every other session route just reads username/roles to\n> authenticate, so it needs the data loaded into the request context but never\n> writes a cookie — hence no need to wrap/buffer the response.\n\n## Changes\n\n### 1. Dependencies (`go.mod` / `go.sum`)\n- Add `github.com/alexedwards/scs/v2` and `github.com/alexedwards/scs/sqlite3store`.\n- Remove `github.com/gorilla/sessions` (+ transitive `gorilla/securecookie`) via `go mod tidy`.\n\n### 2. New DB migration — `sessions` table\n`internal/repository/migrations/sqlite3/12_add-sessions-table.{up,down}.sql`:\n```sql\n-- up\nCREATE TABLE sessions (\n    token  TEXT PRIMARY KEY,\n    data   BLOB NOT NULL,\n    expiry REAL NOT NULL\n);\nCREATE INDEX sessions_expiry_idx ON sessions(expiry);\n-- down\nDROP TABLE IF EXISTS sessions;\n```\nBump `Version` to `12` in `internal/repository/migration.go:28` + add a history\ncomment. `Connect()` only *checks* the version, so existing installs run\n`-migrate-db`; `-init-db` (`cmd/cc-backend/init.go:83`) already migrates fresh DBs.\n\n### 3. `internal/auth/auth.go` — the core swap\nReplace the gorilla import with `github.com/alexedwards/scs/v2`,\n`github.com/alexedwards/scs/sqlite3store`, `encoding/gob`,\n`.../internal/repository`. Drop now-unused `crypto/rand`, `encoding/base64`, `os`\n(verify before removing).\n\n- **Struct** (line 121): `sessionStore *sessions.CookieStore` → `sessionManager *scs.SessionManager`.\n- **Add accessor** so the router can install the middleware:\n  `func (auth *Authentication) SessionManager() *scs.SessionManager { return auth.sessionManager }`\n- **`Init()`** (lines 189–213): delete the whole `SESSION_KEY` block; replace with:\n  ```go\n  gob.Register([]string{}) // user.Projects / user.Roles are []string in session values\n  sm := scs.New()\n  sm.Store = sqlite3store.New(repository.GetConnection().DB.DB)\n  sm.Cookie.Name = \"session\"\n  sm.Cookie.Path = \"/\"\n  sm.Cookie.HttpOnly = true\n  sm.Cookie.SameSite = http.SameSiteLaxMode\n  sm.Cookie.Secure = config.Keys.HTTPSCertFile != \"\" // see note\n  if d, err := time.ParseDuration(config.Keys.SessionMaxAge); err == nil && d != 0 {\n      sm.Lifetime = d\n      authInstance.SessionMaxAge = d\n  } // else keep a long default lifetime (config says 0 == \"no expiry\")\n  authInstance.sessionManager = sm\n  ```\n  > Note on `Secure`: scs sets the flag globally (no per-request option like the old\n  > code). Deriving it from `HTTPSCertFile` is actually *stricter* than today — the\n  > current code only ever sets `Secure=false` and never `true` (gorilla's default is\n  > `false`), so the flag is effectively never set now. Reverse-proxy-TLS deployments\n  > that want `Secure` can get a follow-up config flag.\n- **`SaveSession(rw, r, user)`** (lines 321–354): the login routes are wrapped by\n  `LoadAndSave`, so operate on the request context; the middleware commits + writes\n  the cookie:\n  ```go\n  if err := auth.sessionManager.RenewToken(r.Context()); err != nil { // session-fixation guard\n      cclog.Errorf(\"session renew failed: %s\", err.Error()); http.Error(...); return err\n  }\n  auth.sessionManager.Put(r.Context(), \"username\", user.Username)\n  auth.sessionManager.Put(r.Context(), \"projects\", user.Projects)\n  auth.sessionManager.Put(r.Context(), \"roles\", user.Roles)\n  auth.sessionManager.Put(r.Context(), \"authSource\", int(user.AuthSource))\n  return nil\n  ```\n- **`AuthViaSession(rw, r)`** (lines 129–180): read from the context loaded by the\n  read middleware; keep the same `*schema.User`/error return shape. On a read path\n  there is no commit, so a corrupted session is cleared best-effort by writing an\n  expired `session` cookie (small helper) rather than `Destroy`:\n  ```go\n  if !auth.sessionManager.Exists(r.Context(), \"username\") { return nil, nil } // mirrors session.IsNew\n  username := auth.sessionManager.GetString(r.Context(), \"username\")\n  if username == \"\" { expireSessionCookie(rw); return nil, errors.New(\"invalid session data\") }\n  projects, _ := auth.sessionManager.Get(r.Context(), \"projects\").([]string) // default []string\n  roles, _ := auth.sessionManager.Get(r.Context(), \"roles\").([]string)\n  if len(roles) == 0 { expireSessionCookie(rw); return nil, errors.New(\"invalid session data\") }\n  authSource := auth.sessionManager.GetInt(r.Context(), \"authSource\") // 0 default == AuthViaLocalPassword\n  return &schema.User{Username: username, Projects: projects, Roles: roles, AuthType: schema.AuthSession, AuthSource: schema.AuthSource(authSource)}, nil\n  ```\n  where `expireSessionCookie(rw)` writes `&http.Cookie{Name:\"session\", Path:\"/\", MaxAge:-1, HttpOnly:true, SameSite:http.SameSiteLaxMode}`.\n- **`Logout()`** (lines 610–628): logout is wrapped by `LoadAndSave`, so\n  `_ = auth.sessionManager.Destroy(r.Context())` then call `onsuccess` — the\n  middleware removes the store row and clears the cookie. Drop all gorilla calls.\n- **Add the non-buffering read middleware** on the manager (or a small free func):\n  ```go\n  func (auth *Authentication) LoadSession(next http.Handler) http.Handler {\n      return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {\n          token := \"\"\n          if c, err := r.Cookie(auth.sessionManager.Cookie.Name); err == nil { token = c.Value }\n          ctx, err := auth.sessionManager.Load(r.Context(), token) // absolute expiry enforced here\n          if err != nil { http.Error(w, \"session load failed\", http.StatusInternalServerError); return }\n          next.ServeHTTP(w, r.WithContext(ctx)) // no commit, no ResponseWriter wrap -> no buffering\n      })\n  }\n  ```\n\n### 4. `cmd/cc-backend/server.go` — hybrid wiring\nGrab the manager once: `sm := authHandle.SessionManager()`. All wiring stays inside\nthe existing `if !config.Keys.DisableAuthentication` guards.\n- **Write paths — `LoadAndSave`** (tiny responses): `/login`, `/jwt-login`,\n  `/logout`, e.g. `s.router.Post(\"/login\", sm.LoadAndSave(authHandle.Login(loginFailureHandler)).ServeHTTP)`.\n- **Read paths — `authHandle.LoadSession`** (no buffering), added **before** the\n  existing auth middleware so the session is in ctx when `AuthViaSession` runs:\n  - Secured group (line 247): `secured.Use(authHandle.LoadSession)` before `authHandle.Auth`.\n  - Config group (line 310): `configapi.Use(authHandle.LoadSession)` before `AuthConfigAPI`.\n  - Frontend group (line 320): `frontendapi.Use(authHandle.LoadSession)` before `AuthFrontendAPI`.\n- **Leave `/api`, `/api/metricstore`, `/userapi`, static files unwrapped** (JWT-only / public).\n\n> `/query` lives in the secured group → covered by the non-buffering `LoadSession`,\n> so large GraphQL payloads stream unchanged.\n\n### 5. Frontend cleanup — `web/frontend/src/generic/utils.js`\nIn `init()` remove the dormant Bearer path: delete the `jwt` lookup (lines 24–26)\nand the conditional `fetchOptions` Authorization header (line 31); construct the\nurql `Client` with just `url` + `exchanges`. **Keep** the user-facing\n`/frontend/jwt/` fetch at line ~583 (the \"Gen. JWT\" copy feature for external API\nuse). Rebuild with `make frontend`.\n\n### 6. Remove SESSION_KEY everywhere\n- `.env:8`, `configs/env-template.txt:11`: delete the `SESSION_KEY=` line.\n- `cmd/cc-backend/init.go`: remove `SESSION_KEY` from the embedded `.env` template.\n- `internal/api/api_test.go`, `internal/api/nats_test.go`: remove the\n  `t.Setenv(\"SESSION_KEY\", ...)` calls.\n- Update any `*.md`/docs referencing `SESSION_KEY`.\n\n## Key files\n- `internal/auth/auth.go` — struct, `SessionManager()`, `Init`, `SaveSession`, `AuthViaSession`, `Logout`\n- `cmd/cc-backend/server.go` — scoped `LoadAndSave` wiring\n- `internal/repository/migrations/sqlite3/12_add-sessions-table.{up,down}.sql` (new) + `migration.go` (`Version` → 12)\n- `web/frontend/src/generic/utils.js` — drop dead Bearer branch\n- `go.mod`/`go.sum`, `.env`, `configs/env-template.txt`, `cmd/cc-backend/init.go`, `internal/api/{api,nats}_test.go`\n\n## Verification\n1. `go build ./...`, `make` (incl. `make frontend`), `go vet ./...` clean.\n2. `go mod tidy` removes gorilla/sessions; confirm gone from go.mod/go.sum.\n3. `go test ./...` passes (esp. `internal/api`, `internal/auth`, `internal/repository`).\n4. Fresh DB: `./cc-backend -init-db -add-user demo:admin:demo` then `-server -dev` → DB at version 12.\n5. Existing DB: `-server` without migrating fails with the version-12 message; `-migrate-db` then succeeds.\n6. Manual end-to-end (browser, `-dev`):\n   - Log in → `session` cookie set; a row appears: `sqlite3 var/job.db 'select token,expiry from sessions;'`.\n   - Web UI works: dashboard/job views (GraphQL `/query` via session), `/search`,\n     `/config/*` admin actions, `/frontend/configuration/` saves, `/frontend/logs/`.\n   - **Restart server, reload** → still logged in (durability preserved).\n   - Log out → `sessions` row removed, cookie cleared, back to login page.\n   - Cookie flags: `HttpOnly`, `SameSite=Lax` (and `Secure` when serving HTTPS).\n   - External JWT still works: `/query` with a Bearer token, and `/api/*` /\n     `/userapi/*` endpoints (these are NOT session-wrapped) — confirm large\n     `/api/jobs/metrics/{id}` responses are not buffered/regressed.\n   - OIDC / JWT-cookie login still establishes a session (they call `SaveSession`).\n","planFilePath":"/Users/jan/.claude/plans/replace-the-gorilla-sessions-package-atomic-metcalfe.md"},"caller":{"type":"direct"}}],"stop_reason":"tool_use","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":2559,"cache_read_input_tokens":126532,"output_tokens":619,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":2559,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":619,"cache_read_input_tokens":126532,"cache_creation_input_tokens":2559,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":2559},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Cc8GteKiwb8A1XZcFr7bL","type":"assistant","uuid":"35f6e3dc-213c-40ae-95de-948834ff39a3","timestamp":"2026-06-17T05:24:45.043Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"bce9928c-3f8b-4b95-aa53-56af445a9bbc","version":"2.1.179","gitBranch":"feature/558-replace-gorilla-sessions","slug":"replace-the-gorilla-sessions-package-atomic-metcalfe"}

We are replacing it with\n`github.com/alexedwards/scs/v2`, backed by the existing SQLite DB.\n\nThe packages differ architecturally:\n- **gorilla `CookieStore`** is *stateless* — all data is encrypted into the cookie\n  (signed with `SESSION_KEY`); sessions survive restarts while the key is stable.\n- **scs/v2** is *server-side* — only a random token lives in the cookie; data lives\n  in a store. No encryption key needed.\n\n**Decisions made:**\n- **Store: `sqlite3store`** in the existing SQLite DB (preserves \"stay logged in\n  across restarts\"). Adds dep `github.com/alexedwards/scs/sqlite3store`.\n- **Remove `SESSION_KEY`** — dead code with server-side tokens.\n- **Hybrid middleware (performance-correct):** `LoadAndSave` only on the session\n  *write* paths (login/jwt-login/logout — tiny responses); a custom **non-buffering**\n  read-only load middleware on the session *read* paths (secured/config/frontend).\n  The session is only ever written at login/logout, so the large `/query`\n  GraphQL responses stream with **zero buffering** (no `ResponseWriter` wrap).\n- **`/query` stays dual-auth** (session for the web UI, JWT for external GraphQL\n  clients) — no change to `Auth()`.\n- **Frontend cleanup:** remove the dormant Bearer-JWT branch in the urql client.\n\n### Endpoint analysis (frontend=session, external=JWT)\n\nThe codebase already matches this model. Verified: the web UI's GraphQL client only\nattaches `Authorization: Bearer` if a `jwt` exists in the `cc-config` context\n(`web/frontend/src/generic/utils.js:24-31`), but nothing ever injects one — so the\nUI authenticates `/query` via the **session cookie**; the Bearer branch is dead.\n\n| Route group | Auth today | Caller | LoadAndSave? |\n|---|---|---|---|\n| `/query`, `/search`, pages `/`,`/config`,`/monitoring/*` (`Auth()`) | session (+JWT fallback) | web UI (+ external GraphQL) | **YES** |\n| `/frontend/*` logs,jwt,configuration (`AuthFrontendAPI`) | session only | web UI | **YES** |\n| `/config/*` admin (`AuthConfigAPI`) | session only | web UI (admin) | **YES** |\n| `/login`, `/jwt-login`, `/logout` | session write | web UI | **YES** |\n| `/api/*` (`AuthAPI`) | JWT only | external | **NO** |\n| `/api/metricstore` (`AuthMetricStoreAPI`) | JWT only | external | **NO** |\n| `/userapi/*` (`AuthUserAPI`) | JWT only | external | **NO** |\n| static `/*`, `/img/*`, `/imprint`, `/privacy` | none | browser | **NO** |\n\n`LoadAndSave` buffers the full response to inject the cookie, so it is used **only**\non the tiny login/logout write-paths. The read paths (incl. GraphQL `/query`, which\nwraps large job-metric payloads) use a non-buffering load middleware and stream\nnormally. The JWT data APIs (`/api`, `/userapi`, `/api/metricstore`) get no session\nmiddleware at all. `/frontend/jwt/` (mints a JWT for a logged-in user to use against\nthe external JWT APIs) is the intended session→JWT bridge and stays as-is.\n\n> Why no buffering on reads: the session is mutated only at login (`SaveSession`)\n> and logout (`Destroy`).

Everything builds, all tests pass, the frontend builds, and `gorilla/sessions` is fully removed.\n\n## What changed\n\n**1. DB migration #12** (`internal/repository/migrations/sqlite3/12_add-sessions-table.{up,down}.sql`, `migration.go` `Version`→12)\n- New `sessions` table (`token`, `data`, `expiry` + expiry index) for `sqlite3store`.\n\n**2. `internal/auth/auth.go` — gorilla → scs/v2**\n- `sessionStore *sessions.CookieStore` → `sessionManager *scs.SessionManager`.\n- `Init()`: drops the whole `SESSION_KEY` block; sets up `scs.New()` with `sqlite3store` on the existing DB, cookie name/Path/HttpOnly/SameSite=Lax, `Secure` derived from `HTTPSCertFile`, and `Lifetime` from `SessionMaxAge` (long default when 0 = \"no expiry\").\n- `SaveSession`: `RenewToken` (fixation guard) + `Put` user fields — commit/cookie handled by `LoadAndSave`.\n- `AuthViaSession`: reads from the request context (loaded by `LoadSession`); corrupted sessions cleared via `expireSessionCookie`.\n- `Logout`: `Destroy(ctx)`.\n- New `SessionManager()` accessor and the **non-buffering `LoadSession`** read middleware.\n\n**3. `cmd/cc-backend/server.go` — hybrid wiring**\n- `LoadAndSave` on `/login`, `/jwt-login`, `/logout` (session writes, tiny responses).\n- `LoadSession` (no buffering) on the secured, `/config`, and `/frontend` groups so GraphQL `/query` streams unbuffered.\n- `/api`, `/api/metricstore`, `/userapi`, static files left unwrapped (JWT-only/public).\n\n**4. `web/frontend/src/generic/utils.js`** — removed the dormant Bearer-JWT branch; the urql client now always uses the session cookie. Kept the user-facing \"Gen. JWT\" feature.\n\n**5. `SESSION_KEY` removed** from `.env`, `configs/env-template.txt`, `init.go`'s embedded template, and both test files.\n\n## Verification done\n- `go mod tidy` (gorilla gone), `go build ./...`, `go vet`, `gofmt` — clean.\n- `go test ./...` — all pass; the API/NATS tests run `auth.Init()` against the migrated test DB, exercising the sqlite3store path.\n- `npm run build` — frontend builds.\n\n## Two notes for you\n- **Migration required on existing installs**: starting `-server` against a pre-v12 DB will fail the version check until `./cc-backend -migrate-db` is run; in-flight gorilla cookies become invalid at cutover (users re-login once).\n- **`Secure` flag behavior change**: it's now set globally when this process terminates TLS (`HTTPSCertFile` set). The old per-request logic actually never set `Secure=true` (gorilla's default is false), so this is a net improvement. Reverse-proxy-TLS deployments that want `Secure` would need a follow-up config flag — say the word and I'll add one.\n\nWant me to commit this on the current `feature/558-replace-gorilla-sessions` branch?"}],"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":88,"cache_read_input_tokens":166926,"output_tokens":1153,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":88,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2,"output_tokens":1153,"cache_read_input_tokens":166926,"cache_creation_input_tokens":88,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":88},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Cc8HUx6WHveRy6iFbfnVS","type":"assistant","uuid":"1dc1c943-0458-40d6-bc70-d5e66cad07e0","timestamp":"2026-06-17T05:32:35.040Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"bce9928c-3f8b-4b95-aa53-56af445a9bbc","version":"2.1.179","gitBranch":"feature/558-replace-gorilla-sessions","slug":"replace-the-gorilla-sessions-package-atomic-metcalfe"}

This\n10\tshould not take long. For optimal database performance after the migration it is\n11\trecommended to apply the new `optimize-db` flag, which runs the sqlite `ANALYZE`\n12\tand `VACUUM` commands. Depending on your database size (more then 40GB) the\n13\t`VACUUM` may take up to 2h. You can also run the `ANALYZE` command manually.\n14\tWhile we are confident that the memory issue with the metricstore cleanup move\n15\tpolicy is fixed, it is still recommended to use delete policy for cleanup.\n16\tThis is also the default.\n17\t\n18\t## Changes in 1.5.4\n19\t\n20\t### Security fixes\n21\t\n22\t- **JWT HMAC empty-key bypass (critical)**: `jwtSession.go` now refuses to\n23\t  register when `CROSS_LOGIN_JWT_HS512_KEY` is unset. Previously, an empty HMAC\n24\t  key allowed unauthenticated admin token forgery because `golang-jwt` verifies\n25\t  any HS256/HS512 signature against an empty key.\n26\t- **SQL injection via metric names (critical)**: Metric names supplied through\n27\t  GraphQL (`[String!]`) were interpolated raw into `json_extract` SQL expressions.\n28\t  Names are now validated against `^[a-zA-Z0-9_]+$` in\n29\t  `jobsMetricStatisticsHistogram` and `buildFloatJSONCondition`.\n30\t- **Path traversal via line-protocol tags (critical)**: `cluster` and `host`\n31\t  tags from the metric line protocol flowed unvalidated into `path.Join` for\n32\t  checkpoint/WAL file paths, enabling arbitrary file writes outside the\n33\t  checkpoint root via NATS (unauthenticated) or `POST /api/write`. Path-traversal\n34\t  sequences are now rejected in `DecodeLine` before the tags become path\n35\t  components.\n36\t- **CORS `AllowCredentials` disabled**: CORS middleware no longer sets\n37\t  `AllowCredentials: true`, which was incompatible with `AllowedOrigins: [\"*\"]`\n38\t  and could enable cross-origin credential theft.\n39\t- **HSTS header added**: `Strict-Transport-Security` is now set for all\n40\t  HTTPS connections.\n41\t- **Security response headers**: Added `X-Content-Type-Options: nosniff`,\n42\t  `X-Frame-Options: DENY`, `Referrer-Policy: same-origin`, and a conservative\n43\t  `Content-Security-Policy` (blocks `frame-ancestors`, `object-src`, `base-uri`)\n44\t  to harden against clickjacking and base-tag injection.\n45\t- **Stored XSS in job message**: `job.metaData.message` is now rendered as\n46\t  escaped text (CSS `white-space: pre-wrap`) instead of raw `{@html ...}` in\n47\t  `Job.root` and `JobFootprint`.\n48\t- **SQL injection in tag queries**: The tag-scope `IN` list and manager project\n49\t  subquery in `CountTags` are now parameterized instead of interpolating\n50\t  `user.Username` / `user.Projects` values sourced from OIDC/LDAP.\n51\t- **GraphQL DoS hardening**: Query cost is bounded with `FixedComplexityLimit`\n52\t  (5000). Non-positive `items-per-page` and `page` values are rejected with HTTP\n53\t  400 to prevent integer underflow into unbounded `LIMIT`/`OFFSET` queries.\n54\t- **CSRF defense-in-depth**: State-changing requests with a cross-site\n55\t  `Sec-Fetch-Site` header are now rejected (fails open for non-browser clients),\n56\t  complementing the existing `SameSite=Lax` session cookie.\n57\t- **NATS API security warning**: A startup warning is now logged when NATS\n58\t  subscriptions are enabled, reminding operators that the NATS API has no\n59\t  application-layer authentication and that publish ACLs must be restricted at\n60\t  the broker.\n61\t\n62\t### Bug fixes\n63\t\n64\t- **Roofline legend placement**: Roofline plot legends now use fixed\n65\t  coordinates instead of dynamic placement, preventing the legend from\n66\t  overlapping data points or being rendered off-canvas (#546).\n67\t- **Subcluster usage tab labels**: Subcluster names in the status dashboard\n68\t  usage tabs are no longer force-capitalized; the original cluster-defined\n69\t  casing is preserved.\n70\t- **NodeListRow host filter**: The running-jobs query in the node list row now\n71\t  filters by exact node hostname (`eq`) instead of substring match\n72\t  (`contains`), avoiding incorrect matches when one hostname is a prefix of\n73\t  another.\n74\t- **WAL files not reset on shutdown**: On graceful shutdown the metricstore wrote\n75\t  a final binary snapshot but never rotated the per-host `current.wal` files (the\n76\t  `RotateWALFilesAfterShutdown` helper was defined but never called). The stale\n77\t  WAL files were replayed and then appended to again on the next start, so they\n78\t  grew without bound across restarts and were only ever reset at the next periodic\n79\t  checkpoint. `Shutdown` now rotates the WAL files for all successfully\n80\t  snapshotted hosts.\n81\t\n82\t### Dependencies\n83\t\n84\t- **Go module upgrades**: Refreshed Go module dependencies to their latest\n85\t  compatible versions.\n86\t\n87\t## Changes in 1.5.3\n88\t\n89\t### Bug fixes\n90\t\n91\t- **OIDC role extraction**: Fixed role extraction from OIDC tokens where roles\n92\t  were not correctly parsed from the token claims. Roles are now always\n93\t  requested from the token regardless of other configuration.\n94\t- **OIDC user sync role changes**: `SyncUser` and `UpdateUser` callbacks now\n95\t  allow all role changes, removing a restriction that prevented role updates\n96\t  during OIDC-driven user synchronization.\n97\t- **OIDC projects array**: Projects array from the OIDC token is now submitted\n98\t  and applied when syncing user attributes.\n99\t- **WAL message drops during checkpoint**: WAL writes are now paused during\n100\t  binary checkpoint creation. Previously, disk I/O contention between\n101\t  checkpoint writes and WAL staging caused over 1.4 million dropped messages\n102\t  per checkpoint cycle.\n103\t- **WAL rotation skipped for all nodes**: `RotateWALFiles` used a non-blocking\n104\t  send on a small channel. With thousands of nodes, the channel filled instantly\n105\t  and nearly all hosts were skipped, leaving WAL files unrotated. Replaced with\n106\t  a blocking send using a shared 2-minute deadline.\n107\t- **Log viewer auto-refresh**: Fixed the log viewer component not auto-refreshing\n108\t  correctly.\n109\t- **SameSite cookie setting**: Relaxed the SameSite cookie attribute to improve\n110\t  compatibility with OIDC redirect flows.\n111\t- **WAL not rotated on partial checkpoint failure**: When binary checkpointing\n112\t  failed for some hosts, WAL files for successfully checkpointed hosts were not\n113\t  rotated and the checkpoint timestamp was not advanced. Partial successes now\n114\t  correctly advance the checkpoint and rotate WAL files for completed hosts.\n115\t- **Unbounded WAL file growth**: If binary checkpointing consistently failed for\n116\t  a host, its `current.wal` file grew without limit until disk exhaustion. A new\n117\t  `max-wal-size` configuration option (in the `checkpoints` block) allows setting\n118\t  a per-host WAL size cap in bytes. When exceeded, the WAL is force-rotated.\n119\t  Defaults to 0 (unlimited) for backward compatibility.\n120\t\n121\t- **Doubleranged filter fixes**: Range filters now correctly handle zero as a\n122\t  boundary value. Improved validation and UI text for \"more than equal\" and\n123\t  \"less than equal\" range selections.\n124\t- **Lineprotocol body parsing interrupted**: Switched from `ReadTimeout` to\n125\t  `ReadHeaderTimeout` so that long-running metric submissions are no longer\n126\t  cut off mid-stream.\n127\t- **Checkpoint archiving continues on error**: A single cluster's archiving\n128\t  failure no longer aborts the entire cleanup operation. Errors are collected\n129\t  and reported per cluster.\n130\t- **Parquet row group overflow**: Added periodic flush during checkpoint\n131\t  archiving to prevent exceeding the parquet-go 32k column-write limit.\n132\t- **Removed metrics excluded from subcluster config**: Metrics removed from a\n133\t  subcluster are no longer returned by `GetMetricConfigSubCluster`.\n134\t\n135\t### MetricStore performance\n136\t\n137\t- **WAL writer throughput**: Decoupled WAL file flushing from message processing\n138\t  using a periodic 5-second batch flush (up to 4096 messages per cycle),\n139\t  significantly increasing metric ingestion throughput.\n140\t- **Improved shutdown time**: HTTP shutdown timeout reduced; metricstore and\n141\t  archiver now shut down concurrently. Overall shutdown deadline raised to\n142\t  60 seconds.\n143\t\n144\t### New features\n145\t\n146\t- **Manual checkpoint cleanup flag**: New `-cleanup-checkpoints` CLI flag\n147\t  triggers checkpoint cleanup without starting the server, useful for\n148\t  maintenance windows or automated cleanup scripts.\n149\t- **Explicit node state queries in node view**: Node health and scheduler state\n150\t  are now fetched independently from metric data for fresher status information.\n151\t\n152\t### Development tooling\n153\t\n154\t- **Make targets for formatting and linting**: New `make fmt` and `make lint`\n155\t  targets using `gofumpt` and `golangci-lint`. Configuration added in\n156\t  `.golangci.yml` and `gopls.json`.\n157\t\n158\t### New tools\n159\t\n160\t- **binaryCheckpointReader**: New utility tool (`tools/binaryCheckpointReader`)\n161\t  that reads `.wal` or `.bin` checkpoint files produced by the metricstore\n162\t  WAL/snapshot system and dumps their contents to a human-readable `.txt` file.\n163\t  Useful for debugging and inspecting checkpoint data. Usage:\n164\t  `go run ./tools/binaryCheckpointReader <file.wal|file.bin>`\n165\t\n166\t### Logging improvements\n167\t\n168\t- **Reduced tagger log noise**: Missing metrics and expression evaluation errors\n169\t  in the job classification tagger are now logged at debug level instead of\n170\t  error level.\n171\t\n172\t## Changes in 1.5.2\n173\t\n174\t### Bug fixes\n175\t\n176\t- **Memory spike in parquet writer**: Fixed memory spikes when using the\n177\t  metricstore move (archive) policy with the parquet writer. The writer now\n178\t  processes data in a streaming fashion to avoid accumulating large allocations.\n179\t- **Top list query fixes**: Fixed top list queries in analysis and dashboard\n180\t  views.\n181\t- **Exclude down nodes from HealthCheck**: Down nodes are now excluded from\n182\t  health checks in both the REST and NATS handlers.\n183\t- **Node state priority order**: Node state determination now enforces a\n184\t  priority order. Exception: idle+down results in idle.\n185\t- **Blocking ReceiveNats call**: Fixed a blocking NATS receive call in the\n186\t  metricstore.\n187\t\n188\t### Database performance\n189\t\n190\t- **Reduced insert pressure**: Bulk insert operations (node state updates, user\n191\t  and job cache syncs) now use explicit transactions and deferred inserts,\n192\t  significantly reducing write contention on the SQLite database.\n193\t- **SyncJobs wrapped in transaction**: `SyncJobs` now runs inside a transaction\n194\t  for better consistency and reduced lock contention.\n195\t- **Configurable busy timeout**: New `busy-timeout` configuration option for the\n196\t  SQLite connection. This allows tuning how long the driver waits for a locked\n197\t  database before returning an error, which improves resilience under concurrent\n198\t  write load.\n199\t- **Increased default SQLite timeout**: The default SQLite connection timeout\n200\t  has been raised to reduce spurious timeout errors under load.\n201\t- **Optimized stats queries**: Improved sortby handling in stats queries, fixed\n202\t  cache key passing, and simplified a stats query condition that caused an\n203\t  expensive unnecessary subquery.\n204\t\n205\t### MetricStore performance\n206\t\n207\t- **Sharded WAL consumer**: The WAL consumer is now sharded for significantly\n208\t  higher write throughput.\n209\t- **NATS contention fix**: Fixed contention in the metricstore NATS ingestion\n210\t  path.\n211\t\n212\t### NATS API\n213\t\n214\t- **Nodestate health checks in NATS API**: The NATS node state handler now\n215\t  performs the same metric health checks as the REST API handler, including\n216\t  per-subcluster health checks and `MonitoringStateFailed` fallback for nodes\n217\t  without health data.\n218\t\n219\t### Logging improvements\n220\t\n221\t- **Better error context**: Several repository functions now include the calling\n222\t  function name in error messages for easier diagnosis.\n223\t- **Reduced log noise**: `ErrNoRows` (no results found) is no longer logged as\n224\t  an error in `scanRow`; common \"no rows\" paths are now silent.\n225\t- **Debug-level missing metrics**: Warning about missing metrics in the metric\n226\t  store has been downgraded to debug level to reduce log noise in normal\n227\t  operation.\n228\t- **Checkpoint archiving log**: Added an informational log message when the\n229\t  metricstore checkpoint archiving process runs.\n230\t- **Auth failure context**: Auth failure log messages now include more context\n231\t  information.\n232\t\n233\t### Behavior changes\n234\t\n235\t- **DB-based metricHealth**: Replaced heuristic-based metric health with\n236\t  DB-based metric health for the node view, providing more accurate health\n237\t  status information.\n238\t- **Removed minRunningFor filter remnants**: Cleaned up remaining `minRunningFor`\n239\t  references from the GraphQL schema and query builder.\n240\t\n241\t### Frontend\n242\t\n243\t- **Streamlined statsSeries**: Unified stats series calculation and rendering\n244\t  across plot components.\n245\t- **Clarified plot titles**: Improved titles in dashboard and health views.\n246\t- **Bumped frontend dependencies**: Updated frontend dependencies to latest\n247\t  versions.\n248\t\n249\t### Dependencies\n250\t\n251\t- **cc-lib upgraded**: Updated to latest cc-lib version.\n252\t\n253\t## Known issues\n254\t\n255\t- The new dynamic memory management is not bullet proof yet across restarts.\n256\t  Buffers that are kept outside the retention period may be lost across a\n257\t  restart. We will fix that in a subsequent patch release.\n258\t- To use the new log viewer (which is only working when starting cc-backend with\n259\t  systemd) in the admin interface the user under which the cc-backend process is\n260\t  running has to be allowed to execute the journalctl command.\n261\t- The user configuration keys for the ui have changed. Therefore old user\n262\t  configuration persisted in the database is not used anymore. It is recommended\n263\t  to configure the metrics shown in the ui-config section and remove all records\n264\t  in the table after the update.\n265\t- Currently energy footprint metrics of type energy are ignored for calculating\n266\t  total energy.\n267\t- With energy footprint metrics of type power the unit is ignored and it is\n268\t  assumed the metric has the unit Watt.\n269\t\n270\t## Changes in 1.5.1\n271\t\n272\t### Database\n273\t\n274\t- **New migration (version 11)**: Optimized database index count and added covering indexes for stats queries for significantly improved query performance\n275\t- **Migration 9 fix**: Removed redundant indices from migration 9 that are superseded by migration 11\n276\t- **Optional DB optimization flag**: Added `-optimize-db` CLI flag to run `ANALYZE` on demand; removed automatic ANALYZE on startup\n277\t- **Selective stats queries**: Stats queries are now selective, reducing unnecessary computation\n278\t- **User list paging**: Added paging support to the user list for better scalability\n279\t- **SQLite configuration hardening**: Sanitized SQLite configuration with new configurable options; fixes large heap allocations in the SQLite driver\n280\t- **Query cancellation**: Long-running database queries can now be cancelled\n281\t- **Resource leak fix**: Added missing `defer Close()` calls for all query result sets\n282\t\n283\t### Bug fixes\n284\t\n285\t- **Segfault when taggers misconfigured**: Fixed crash when `enable-job-taggers` is set but tagger rule directories are missing\n286\t- **GroupBy stats query complexity**: Reduced complexity for `groupBy` statistics queries\n287\t- **Ranged filter conditions**: Fixed GT and LT conditions in ranged filters\n288\t- **Energy filter preset**: Reduced energy filter preset to a more practical default\n289\t- **JSON validity check**: Fixed wrong field being checked for JSON validity\n290\t- **Tagger float rounding**: Fixed rounding of floats in tagger messages\n291\t- **Node view null safety**: Added null-safe checks in node view to prevent runtime errors\n292\t- **Public dashboard null safety**: Added null-safe checks in the public dashboard to prevent runtime errors\n293\t\n294\t### Frontend\n295\t\n296\t- **Bumped patch versions**: Updated frontend dependencies to latest patch versions\n297\t\n298\t### Documentation\n299\t\n300\t- **New DB config options**: Added new database configuration options to README\n301\t\n302\t---\n303\t\n304\t_The sections below document all features and changes introduced in the 1.5.0 major release, which 1.5.1 is based on._\n305\t\n306\t## Breaking changes\n307\t\n308\t### Configuration changes\n309\t\n310\t- **JSON attribute naming**: All JSON configuration attributes now use `kebab-case`\n311\t  style consistently (e.g., `api-allowed-ips` instead of `apiAllowedIPs`).\n312\t  Update your `config.json` accordingly.\n313\t- **Removed `disable-archive` option**: This obsolete configuration option has been removed.\n314\t- **Removed `clusters` config section**: The separate clusters configuration section\n315\t  has been removed.

This should be transparent to users but affects how middleware and\n323\t  routes are composed. A proper 404 handler is now in place.\n324\t- **MetricStore moved**: The `metricstore` package has been moved from `internal/`\n325\t  to `pkg/` as it is now part of the public API.\n326\t- **MySQL/MariaDB support removed**: Only SQLite is now supported as the database backend.\n327\t- **Archive to Cleanup renaming**: Archive-related functions have been refactored\n328\t  and renamed to

`cc-backend` version 1.5.4\n\nSupports job archive version 3 and database version 11.\n\nThis is a security and bugfix release of `cc-backend`, the API backend and\nfrontend implementation of ClusterCockpit.\nFor release specific notes visit the [ClusterCockpit Documentation](https://clusterockpit.org/docs/release/).\nIf you are upgrading from v1.5.1 no database migration is required.\nIf you are upgrading from v1.5.0 you need to do another DB migration. This\nshould not take long. For optimal database performance after the migration it is\nrecommended to apply the new `optimize-db` flag, which runs the sqlite `ANALYZE`\nand `VACUUM` commands. Depending on your database size (more then 40GB) the\n`VACUUM` may take up to 2h. You can also run the `ANALYZE` command manually.\nWhile we are confident that the memory issue with the metricstore cleanup move\npolicy is fixed, it is still recommended to use delete policy for cleanup.\nThis is also the default.\n\n## Changes in 1.5.4\n\n### Security fixes\n\n- **JWT HMAC empty-key bypass (critical)**: `jwtSession.go` now refuses to\n  register when `CROSS_LOGIN_JWT_HS512_KEY` is unset. Previously, an empty HMAC\n  key allowed unauthenticated admin token forgery because `golang-jwt` verifies\n  any HS256/HS512 signature against an empty key.\n- **SQL injection via metric names (critical)**: Metric names supplied through\n  GraphQL (`[String!]`) were interpolated raw into `json_extract` SQL expressions.\n  Names are now validated against `^[a-zA-Z0-9_]+$` in\n  `jobsMetricStatisticsHistogram` and `buildFloatJSONCondition`.\n- **Path traversal via line-protocol tags (critical)**: `cluster` and `host`\n  tags from the metric line protocol flowed unvalidated into `path.Join` for\n  checkpoint/WAL file paths, enabling arbitrary file writes outside the\n  checkpoint root via NATS (unauthenticated) or `POST /api/write`. Path-traversal\n  sequences are now rejected in `DecodeLine` before the tags become path\n  components.\n- **CORS `AllowCredentials` disabled**: CORS middleware no longer sets\n  `AllowCredentials: true`, which was incompatible with `AllowedOrigins: [\"*\"]`\n  and could enable cross-origin credential theft.\n- **HSTS header added**: `Strict-Transport-Security` is now set for all\n  HTTPS connections.\n- **Security response headers**: Added `X-Content-Type-Options: nosniff`,\n  `X-Frame-Options: DENY`, `Referrer-Policy: same-origin`, and a conservative\n  `Content-Security-Policy` (blocks `frame-ancestors`, `object-src`, `base-uri`)\n  to harden against clickjacking and base-tag injection.\n- **Stored XSS in job message**: `job.metaData.message` is now rendered as\n  escaped text (CSS `white-space: pre-wrap`) instead of raw `{@html ...}` in\n  `Job.root` and `JobFootprint`.\n- **SQL injection in tag queries**: The tag-scope `IN` list and manager project\n  subquery in `CountTags` are now parameterized instead of interpolating\n  `user.Username` / `user.Projects` values sourced from OIDC/LDAP.\n- **GraphQL DoS hardening**: Query cost is bounded with `FixedComplexityLimit`\n  (5000). Non-positive `items-per-page` and `page` values are rejected with HTTP\n  400 to prevent integer underflow into unbounded `LIMIT`/`OFFSET` queries.\n- **CSRF defense-in-depth**: State-changing requests with a cross-site\n  `Sec-Fetch-Site` header are now rejected (fails open for non-browser clients),\n  complementing the existing `SameSite=Lax` session cookie.\n- **NATS API security warning**: A startup warning is now logged when NATS\n  subscriptions are enabled, reminding operators that the NATS API has no\n  application-layer authentication and that publish ACLs must be restricted at\n  the broker.\n\n### Bug fixes\n\n- **Roofline legend placement**: Roofline plot legends now use fixed\n  coordinates instead of dynamic placement, preventing the legend from\n  overlapping data points or being rendered off-canvas (#546).\n- **Subcluster usage tab labels**: Subcluster names in the status dashboard\n  usage tabs are no longer force-capitalized; the original cluster-defined\n  casing is preserved.\n- **NodeListRow host filter**: The running-jobs query in the node list row now\n  filters by exact node hostname (`eq`) instead of substring match\n  (`contains`), avoiding incorrect matches when one hostname is a prefix of\n  another.\n- **WAL files not reset on shutdown**: On graceful shutdown the metricstore wrote\n  a final binary snapshot but never rotated the per-host `current.wal` files (the\n  `RotateWALFilesAfterShutdown` helper was defined but never called). The stale\n  WAL files were replayed and then appended to again on the next start, so they\n  grew without bound across restarts and were only ever reset at the next periodic\n  checkpoint. `Shutdown` now rotates the WAL files for all successfully\n  snapshotted hosts.\n\n### Dependencies\n\n- **Go module upgrades**: Refreshed Go module dependencies to their latest\n  compatible versions.\n\n## Changes in 1.5.3\n\n### Bug fixes\n\n- **OIDC role extraction**: Fixed role extraction from OIDC tokens where roles\n  were not correctly parsed from the token claims. Roles are now always\n  requested from the token regardless of other configuration.\n- **OIDC user sync role changes**: `SyncUser` and `UpdateUser` callbacks now\n  allow all role changes, removing a restriction that prevented role updates\n  during OIDC-driven user synchronization.\n- **OIDC projects array**: Projects array from the OIDC token is now submitted\n  and applied when syncing user attributes.\n- **WAL message drops during checkpoint**: WAL writes are now paused during\n  binary checkpoint creation. Previously, disk I/O contention between\n  checkpoint writes and WAL staging caused over 1.4 million dropped messages\n  per checkpoint cycle.\n- **WAL rotation skipped for all nodes**: `RotateWALFiles` used a non-blocking\n  send on a small channel. With thousands of nodes, the channel filled instantly\n  and nearly all hosts were skipped, leaving WAL files unrotated. Replaced with\n  a blocking send using a shared 2-minute deadline.\n- **Log viewer auto-refresh**: Fixed the log viewer component not auto-refreshing\n  correctly.\n- **SameSite cookie setting**: Relaxed the SameSite cookie attribute to improve\n  compatibility with OIDC redirect flows.\n- **WAL not rotated on partial checkpoint failure**: When binary checkpointing\n  failed for some hosts, WAL files for successfully checkpointed hosts were not\n  rotated and the checkpoint timestamp was not advanced. Partial successes now\n  correctly advance the checkpoint and rotate WAL files for completed hosts.\n- **Unbounded WAL file growth**: If binary checkpointing consistently failed for\n  a host, its `current.wal` file grew without limit until disk exhaustion. A new\n  `max-wal-size` configuration option (in the `checkpoints` block) allows setting\n  a per-host WAL size cap in bytes. When exceeded, the WAL is force-rotated.\n  Defaults to 0 (unlimited) for backward compatibility.\n\n- **Doubleranged filter fixes**: Range filters now correctly handle zero as a\n  boundary value. Improved validation and UI text for \"more than equal\" and\n  \"less than equal\" range selections.\n- **Lineprotocol body parsing interrupted**: Switched from `ReadTimeout` to\n  `ReadHeaderTimeout` so that long-running metric submissions are no longer\n  cut off mid-stream.\n- **Checkpoint archiving continues on error**: A single cluster's archiving\n  failure no longer aborts the entire cleanup operation. Errors are collected\n  and reported per cluster.\n- **Parquet row group overflow**: Added periodic flush during checkpoint\n  archiving to prevent exceeding the parquet-go 32k column-write limit.\n- **Removed metrics excluded from subcluster config**: Metrics removed from a\n  subcluster are no longer returned by `GetMetricConfigSubCluster`.\n\n### MetricStore performance\n\n- **WAL writer throughput**: Decoupled WAL file flushing from message processing\n  using a periodic 5-second batch flush (up to 4096 messages per cycle),\n  significantly increasing metric ingestion throughput.\n- **Improved shutdown time**: HTTP shutdown timeout reduced; metricstore and\n  archiver now shut down concurrently. Overall shutdown deadline raised to\n  60 seconds.\n\n### New features\n\n- **Manual checkpoint cleanup flag**: New `-cleanup-checkpoints` CLI flag\n  triggers checkpoint cleanup without starting the server, useful for\n  maintenance windows or automated cleanup scripts.\n- **Explicit node state queries in node view**: Node health and scheduler state\n  are now fetched independently from metric data for fresher status information.\n\n### Development tooling\n\n- **Make targets for formatting and linting**: New `make fmt` and `make lint`\n  targets using `gofumpt` and `golangci-lint`. Configuration added in\n  `.golangci.yml` and `gopls.json`.\n\n### New tools\n\n- **binaryCheckpointReader**: New utility tool (`tools/binaryCheckpointReader`)\n  that reads `.wal` or `.bin` checkpoint files produced by the metricstore\n  WAL/snapshot system and dumps their contents to a human-readable `.txt` file.\n  Useful for debugging and inspecting checkpoint data. Usage:\n  `go run ./tools/binaryCheckpointReader <file.wal|file.bin>`\n\n### Logging improvements\n\n- **Reduced tagger log noise**: Missing metrics and expression evaluation errors\n  in the job classification tagger are now logged at debug level instead of\n  error level.\n\n## Changes in 1.5.2\n\n### Bug fixes\n\n- **Memory spike in parquet writer**: Fixed memory spikes when using the\n  metricstore move (archive) policy with the parquet writer. The writer now\n  processes data in a streaming fashion to avoid accumulating large allocations.\n- **Top list query fixes**: Fixed top list queries in analysis and dashboard\n  views.\n- **Exclude down nodes from HealthCheck**: Down nodes are now excluded from\n  health checks in both the REST and NATS handlers.\n- **Node state priority order**: Node state determination now enforces a\n  priority order. Exception: idle+down results in idle.\n- **Blocking ReceiveNats call**: Fixed a blocking NATS receive call in the\n  metricstore.\n\n### Database performance\n\n- **Reduced insert pressure**: Bulk insert operations (node state updates, user\n  and job cache syncs) now use explicit transactions and deferred inserts,\n  significantly reducing write contention on the SQLite database.\n- **SyncJobs wrapped in transaction**: `SyncJobs` now runs inside a transaction\n  for better consistency and reduced lock contention.\n- **Configurable busy timeout**: New `busy-timeout` configuration option for the\n  SQLite connection. This allows tuning how long the driver waits for a locked\n  database before returning an error, which improves resilience under concurrent\n  write load.\n- **Increased default SQLite timeout**: The default SQLite connection timeout\n  has been raised to reduce spurious timeout errors under load.\n- **Optimized stats queries**: Improved sortby handling in stats queries, fixed\n  cache key passing, and simplified a stats query condition that caused an\n  expensive unnecessary subquery.\n\n### MetricStore performance\n\n- **Sharded WAL consumer**: The WAL consumer is now sharded for significantly\n  higher write throughput.\n- **NATS contention fix**: Fixed contention in the metricstore NATS ingestion\n  path.\n\n### NATS API\n\n- **Nodestate health checks in NATS API**: The NATS node state handler now\n  performs the same metric health checks as the REST API handler, including\n  per-subcluster health checks and `MonitoringStateFailed` fallback for nodes\n  without health data.\n\n### Logging improvements\n\n- **Better error context**: Several repository functions now include the calling\n  function name in error messages for easier diagnosis.\n- **Reduced log noise**: `ErrNoRows` (no results found) is no longer logged as\n  an error in `scanRow`; common \"no rows\" paths are now silent.\n- **Debug-level missing metrics**: Warning about missing metrics in the metric\n  store has been downgraded to debug level to reduce log noise in normal\n  operation.\n- **Checkpoint archiving log**: Added an informational log message when the\n  metricstore checkpoint archiving process runs.\n- **Auth failure context**: Auth failure log messages now include more context\n  information.\n\n### Behavior changes\n\n- **DB-based metricHealth**: Replaced heuristic-based metric health with\n  DB-based metric health for the node view, providing more accurate health\n  status information.\n- **Removed minRunningFor filter remnants**: Cleaned up remaining `minRunningFor`\n  references from the GraphQL schema and query builder.\n\n### Frontend\n\n- **Streamlined statsSeries**: Unified stats series calculation and rendering\n  across plot components.\n- **Clarified plot titles**: Improved titles in dashboard and health views.\n- **Bumped frontend dependencies**: Updated frontend dependencies to latest\n  versions.\n\n### Dependencies\n\n- **cc-lib upgraded**: Updated to latest cc-lib version.\n\n## Known issues\n\n- The new dynamic memory management is not bullet proof yet across restarts.\n  Buffers that are kept outside the retention period may be lost across a\n  restart. We will fix that in a subsequent patch release.\n- To use the new log viewer (which is only working when starting cc-backend with\n  systemd) in the admin interface the user under which the cc-backend process is\n  running has to be allowed to execute the journalctl command.\n- The user configuration keys for the ui have changed. Therefore old user\n  configuration persisted in the database is not used anymore. It is recommended\n  to configure the metrics shown in the ui-config section and remove all records\n  in the table after the update.\n- Currently energy footprint metrics of type energy are ignored for calculating\n  total energy.\n- With energy footprint metrics of type power the unit is ignored and it is\n  assumed the metric has the unit Watt.\n\n## Changes in 1.5.1\n\n### Database\n\n- **New migration (version 11)**: Optimized database index count and added covering indexes for stats queries for significantly improved query performance\n- **Migration 9 fix**: Removed redundant indices from migration 9 that are superseded by migration 11\n- **Optional DB optimization flag**: Added `-optimize-db` CLI flag to run `ANALYZE` on demand; removed automatic ANALYZE on startup\n- **Selective stats queries**: Stats queries are now selective, reducing unnecessary computation\n- **User list paging**: Added paging support to the user list for better scalability\n- **SQLite configuration hardening**: Sanitized SQLite configuration with new configurable options; fixes large heap allocations in the SQLite driver\n- **Query cancellation**: Long-running database queries can now be cancelled\n- **Resource leak fix**: Added missing `defer Close()` calls for all query result sets\n\n### Bug fixes\n\n- **Segfault when taggers misconfigured**: Fixed crash when `enable-job-taggers` is set but tagger rule directories are missing\n- **GroupBy stats query complexity**: Reduced complexity for `groupBy` statistics queries\n- **Ranged filter conditions**: Fixed GT and LT conditions in ranged filters\n- **Energy filter preset**: Reduced energy filter preset to a more practical default\n- **JSON validity check**: Fixed wrong field being checked for JSON validity\n- **Tagger float rounding**: Fixed rounding of floats in tagger messages\n- **Node view null safety**: Added null-safe checks in node view to prevent runtime errors\n- **Public dashboard null safety**: Added null-safe checks in the public dashboard to prevent runtime errors\n\n### Frontend\n\n- **Bumped patch versions**: Updated frontend dependencies to latest patch versions\n\n### Documentation\n\n- **New DB config options**: Added new database configuration options to README\n\n---\n\n_The sections below document all features and changes introduced in the 1.5.0 major release, which 1.5.1 is based on._\n\n## Breaking changes\n\n### Configuration changes\n\n- **JSON attribute naming**: All JSON configuration attributes now use `kebab-case`\n  style consistently (e.g., `api-allowed-ips` instead of `apiAllowedIPs`).\n  Update your `config.json` accordingly.\n- **Removed `disable-archive` option**: This obsolete configuration option has been removed.\n- **Removed `clusters` config section**: The separate clusters configuration section\n  has been removed.

Run `./cc-backend -migrate-db` after upgrading; the new\n`sessions` table is created automatically (a fresh `-init-db` also creates it).\nExisting login sessions are invalidated by the upgrade, so users have to log in\nagain once. See the behavior changes below regarding the session cookie `Secure`\nflag and the removal of the `SESSION_KEY` environment variable.\nFor release specific notes visit the [ClusterCockpit Documentation](https://clusterockpit.org/docs/release/).\n\n## Changes in 1.6.0\n\n### Behavior changes\n\n- **Session backend replaced (`gorilla/sessions` → `alexedwards/scs`)**: Browser\n  sessions are now managed by `github.com/alexedwards/scs/v2` with server-side\n  storage in the SQLite database (new `sessions` table, database version 12)\n  instead of `gorilla/sessions` client-side cookie storage. Only an opaque random\n  token is stored in the cookie; the session payload lives server-side. Sessions\n  still survive backend restarts. This requires the database migration noted above\n  and invalidates existing sessions.\n- **Session cookie `Secure` flag**: The `Secure` attribute on the session cookie\n  is now derived from the server configuration — it is set when cc-backend\n  terminates TLS itself (`https-cert-file` and `https-key-file` configured) and\n  unset otherwise. Previously the flag was effectively never set. Deployments that\n  terminate TLS at a reverse proxy and want the `Secure` flag should serve\n  cc-backend over HTTPS directly for now.\n- **`SESSION_KEY` removed**: The `SESSION_KEY` environment variable is no longer\n  used and should be removed from your `.env`. Server-side sessions use random\n  tokens, so no cookie-signing secret is required.

Previously the flag was effectively never set. Deployments that\n  terminate TLS at a reverse proxy and want the `Secure` flag should serve\n  cc-backend over HTTPS directly for now.\n- **`SESSION_KEY` removed**: The `SESSION_KEY` environment variable is no longer\n  used and should be removed from your `.env`. Server-side sessions use random\n  tokens, so no cookie-signing secret is required.

Run `./cc-backend -migrate-db` after upgrading; the new\n7\t`sessions` table is created automatically (a fresh `-init-db` also creates it).\n8\tExisting login sessions are invalidated by the upgrade, so users have to log in\n9\tagain once. See the behavior changes below regarding the session cookie `Secure`\n10\tflag and the removal of the `SESSION_KEY` environment variable.\n11\tFor release specific notes visit the [ClusterCockpit Documentation](https://clusterockpit.org/docs/release/).\n12\t\n13\t## Changes in 1.6.0\n14\t\n15\t### Behavior changes\n16\t\n17\t- **Session backend replaced (`gorilla/sessions` → `alexedwards/scs`)**: Browser\n18\t  sessions are now managed by `github.com/alexedwards/scs/v2` with server-side\n19\t  storage in the SQLite database (new `sessions` table, database version 12)\n20\t  instead of `gorilla/sessions` client-side cookie storage. Only an opaque random\n21\t  token is stored in the cookie; the session payload lives server-side. Sessions\n22\t  still survive backend restarts. This requires the database migration noted above\n23\t  and invalidates existing sessions.\n24\t- **Session cookie `Secure` flag**: The `Secure` attribute on the session cookie\n25\t  is now derived from the server configuration — it is set when cc-backend\n26\t  terminates TLS itself (`https-cert-file` and `https-key-file` configured) and\n27\t  unset otherwise. Previously the flag was effectively never set.

Run `./cc-backend -migrate-db` after upgrading; the new\n`sessions` table is created automatically (a fresh `-init-db` also creates it).\nExisting login sessions are invalidated by the upgrade, so users have to log in\nagain once. See the behavior changes below regarding the session cookie `Secure`\nflag and the removal of the `SESSION_KEY` environment variable.\nFor release specific notes visit the [ClusterCockpit Documentation](https://clusterockpit.org/docs/release/).\n\n## Changes in 1.6.0\n\n### Behavior changes\n\n- **Session backend replaced (`gorilla/sessions` → `alexedwards/scs`)**: Browser\n  sessions are now managed by `github.com/alexedwards/scs/v2` with server-side\n  storage in the SQLite database (new `sessions` table, database version 12)\n  instead of `gorilla/sessions` client-side cookie storage. Only an opaque random\n  token is stored in the cookie; the session payload lives server-side. Sessions\n  still survive backend restarts. This requires the database migration noted above\n  and invalidates existing sessions.\n- **Session cookie `Secure` flag**: The `Secure` attribute on the session cookie\n  is now derived from the server configuration — it is set when cc-backend\n  terminates TLS itself (`https-cert-file` and `https-key-file` configured) and\n  unset otherwise. Previously the flag was effectively never set. Deployments that\n  terminate TLS at a reverse proxy and want the `Secure` flag should serve\n  cc-backend over HTTPS directly for now.\n- **`SESSION_KEY` removed**: The `SESSION_KEY` environment variable is no longer\n  used and should be removed from your `.env`. Server-side sessions use random\n  tokens, so no cookie-signing secret is required. It is ignored if left in place.\n\n### Dependencies\n\n- **Added** `github.com/alexedwards/scs/v2` and\n  `github.com/alexedwards/scs/sqlite3store`.\n- **Removed** `github.com/gorilla/sessions` (and `github.com/gorilla/securecookie`).\n\n## Changes in 1.5.4\n\nSupports job archive version 3 and database version 11.","numLines":42,"startLine":1,"totalLines":604}},"sourceToolAssistantUUID":"97738359-cd9b-463c-b624-dce272a8d434","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"bce9928c-3f8b-4b95-aa53-56af445a9bbc","version":"2.1.179","gitBranch":"feature/558-replace-gorilla-sessions","slug":"replace-the-gorilla-sessions-package-atomic-metcalfe"}
