 ## Purpose
 
 This file tells automated coding agents (and humans) where to find the single sources of truth for building, testing, and contributing to PhotoPrism.

+- Code Maps: `CODEMAP.md` (Backend/Go), `frontend/CODEMAP.md` (Frontend/JS)
+
+### Specifications (Versioning & Usage)
+
+- Always use the latest spec version for a topic (highest `-vN`), as linked from `specs/README.md` and the portal cheatsheet (`specs/portal/README.md`).
+- Testing Guides: `specs/dev/backend-testing.md` (Backend/Go), `specs/dev/frontend-testing.md` (Frontend/JS)
+- Whenever the Change Management instructions for a document require it, publish changes as a new file with an incremented version suffix (e.g., `*-v3.md`) rather than overwriting the original file.
+- Older spec versions remain in the repo for historical reference but are not linked from the main TOC. Do not base new work on superseded files (e.g., `*-v1.md` when `*-v2.md` exists).
+
+Note on specs repository availability
+- The `specs/` repository may be private and is not guaranteed to be present in every clone or environment. Do not add Makefile targets in the main project that depend on `specs/` paths. When `specs/` is available, run its tools directly (e.g., `bash specs/scripts/lint-status.sh`).

   - Full unit test suite: `make test` (runs backend and frontend tests)
   - Test frontend/backend: `make test-js` and `make test-go`
   - Go packages: `go test` (all tests) or `go test -run <name>` (specific tests only)
+- Go tests live beside sources: for `path/to/pkg/<file>.go`, add tests in `path/to/pkg/<file>_test.go` (create if missing). For the same function, group related cases as `t.Run(...)` sub-tests (table-driven where helpful).
 - Frontend unit tests are driven by Vitest; see scripts in `frontend/package.json`
   - Vitest watch/coverage: `make vitest-watch` and `make vitest-coverage`
 - Acceptance tests: use the `acceptance-*` targets in the `Makefile`
 
+### FFmpeg Tests & Hardware Gating
+
+- By default, do not run GPU/HW encoder integrations in CI. Gate with `PHOTOPRISM_FFMPEG_ENCODER` (one of: `vaapi`, `intel`, `nvidia`).
+- Negative-path tests should remain fast and always run:
+  - Missing ffmpeg binary → immediate exec error.
+  - Unwritable destination → command fails without creating files.
+- Prefer command-string assertions when hardware is unavailable; enable HW runs locally only when a device is configured.
+
+### Fast, Focused Test Recipes
+
+- Filesystem + archives (fast): `go test ./pkg/fs -run 'Copy|Move|Unzip' -count=1`
+- Media helpers (fast): `go test ./pkg/media/... -count=1`
+- Thumbnails (libvips, moderate): `go test ./internal/thumb/... -count=1`
+- FFmpeg command builders (moderate): `go test ./internal/ffmpeg -run 'Remux|Transcode|Extract' -count=1`
+
+### CLI Testing Gotchas (Go)
+
+- Exit codes and `os.Exit`:
+  - `urfave/cli` calls `os.Exit(code)` when a command returns `cli.Exit(...)`, which will terminate `go test` abruptly (often after logs like `http 401:`).
+  - Use the test helper `RunWithTestContext` (in `internal/commands/commands_test.go`) which temporarily overrides `cli.OsExiter` so the process doesn’t exit; you still receive the error to assert `ExitCoder`.
+  - If you only need to assert the exit code and don’t need printed output, you can invoke `cmd.Action(ctx)` directly and check `err.(cli.ExitCoder).ExitCode()`.
+- Non‑interactive mode: set `PHOTOPRISM_CLI=noninteractive` and/or pass `--yes` to avoid prompts that block tests and CI.
+- SQLite DSN in tests:
+  - `config.NewTestConfig("<pkg>")` defaults to SQLite with a per‑suite DSN like `.<pkg>.db`. Don’t assert an empty DSN for SQLite.
+  - Clean up any per‑suite SQLite files in tests with `t.Cleanup(func(){ _ = os.Remove(dsn) })` if you capture the DSN.
+
 ## Code Style & Lint
 
 - Go: run `make fmt-go swag-fmt` to reformat the backend code + Swagger annotations (see `Makefile` for additional targets)
   - Doc comments for packages and exported identifiers must be complete sentences that begin with the name of the thing being described and end with a period.
   - For short examples inside comments, indent code rather than using backticks; godoc treats indented blocks as preformatted.
+- Every Go package must contain a `<package>.go` file in its root (for example, `internal/auth/jwt/jwt.go`) with the standard license header and a short package description comment explaining its purpose.
 - JS/Vue: use the lint/format scripts in `frontend/package.json` (ESLint + Prettier)
 - All added code and tests **must** be formatted according to our standards.
 
+> Remember to update the `**Last Updated:**` line at the top whenever you edit these guidelines or other files containing a timestamp.
+
 ## Safety & Data
 
 - Never commit secrets, local configurations, or cache files. Use environment variables or a local `.env`.
   - Ensure `.env` and `.local` are ignored in `.gitignore` and `.dockerignore`.
 - Prefer using existing caches, workers, and batching strategies referenced in code and `Makefile`. Consider memory/CPU impact; suggest benchmarks or profiling only when justified.
 - Do not run destructive commands against production data. Prefer ephemeral volumes and test fixtures when running acceptance tests.
+
+### Filesystem Permissions & io/fs Aliasing (Go)
+
+- Always use our shared permission variables from `pkg/fs` when creating files/directories:
+  - Directories: `fs.ModeDir` (0o755 with umask)
+  - Regular files: `fs.ModeFile` (0o644 with umask)
+  - Config files: `fs.ModeConfigFile` (default 0o664)
+  - Secrets/tokens: `fs.ModeSecretFile` (default 0o600)
+  - Backups: `fs.ModeBackupFile` (default 0o600)
+- Do not pass stdlib `io/fs` flags (e.g., `fs.ModeDir`) to functions expecting permission bits.
+  - When importing the stdlib package, alias it to avoid collisions: `iofs "io/fs"` or `gofs "io/fs"`.
+  - Our package is `github.com/photoprism/photoprism/pkg/fs` and provides the only approved permission constants for `os.MkdirAll`, `os.WriteFile`, `os.OpenFile`, and `os.Chmod`.
+- Prefer `filepath.Join` for filesystem paths; reserve `path.Join` for URL paths.
+
+### File I/O — Overwrite Policy (force semantics)
+
+- Default is safety-first: callers must not overwrite non-empty destination files unless they opt-in with a `force` flag.
+- Replacing empty destination files is allowed without `force=true` (useful for placeholder files).
+- Open destinations with `O_WRONLY|O_CREATE|O_TRUNC` to avoid trailing bytes when overwriting; use `O_EXCL` when the caller must detect collisions.
+- Where this lives:
+  - App-level helpers: `internal/photoprism/mediafile.go` (`MediaFile.Copy/Move`).
+  - Reusable utils: `pkg/fs/copy.go`, `pkg/fs/move.go`.
+- When to set `force=true`:
+  - Explicit “replace” actions or admin tools where the user confirmed overwrite.
+  - Not for import/index flows; Originals must not be clobbered.
+
+### Archive Extraction — Security Checklist
+
+- Always validate ZIP entry names with a safe join; reject:
+  - absolute paths (e.g., `/etc/passwd`).
+  - Windows drive/volume paths (e.g., `C:\\…` or `C:/…`).
+  - any entry that escapes the target directory after cleaning (path traversal via `..`).
+- Enforce per-file and total size budgets to prevent resource exhaustion.
+- Skip OS metadata directories (e.g., `__MACOSX`) and reject suspicious names.
+- Where this lives: `pkg/fs/zip.go` (`Unzip`, `UnzipFile`, `safeJoin`).
+- Tests to keep:
+  - Absolute/volume paths rejected (Windows-specific backslash path covered on Windows).
+  - `..` traversal skipped; `__MACOSX` skipped.
+  - Per-file and total size limits enforced; directory entries created; nested paths extracted safely.
+
 - Examples assume a Linux/Unix shell. For Windows specifics, see the Developer Guide FAQ:
   https://docs.photoprism.app/developer-guide/faq/#can-your-development-environment-be-used-under-windows
 
+### HTTP Download — Security Checklist
+
+- Use the shared safe HTTP helper instead of ad‑hoc `net/http` code:
+  - Package: `pkg/service/http/safe` → `safe.Download(destPath, url, *safe.Options)`.
+  - Default policy in this repo: allow only `http/https`, enforce timeouts and max size, write to a `0600` temp file then rename.
+- SSRF protection (mandatory unless explicitly needed for tests):
+  - Set `AllowPrivate=false` to block private/loopback/multicast/link‑local ranges.
+  - All redirect targets are validated; the final connected peer IP is also checked.
+  - Prefer an image‑focused `Accept` header for image downloads: `"image/jpeg, image/png, */*;q=0.1"`.
+- Avatars and small images: use the thin wrapper in `internal/thumb/avatar.SafeDownload` which applies stricter defaults (15s timeout, 10 MiB, `AllowPrivate=false`).
+- Tests using `httptest.Server` on 127.0.0.1 must pass `AllowPrivate=true` explicitly to succeed.
+- Keep per‑resource size budgets small; rely on `io.LimitReader` + `Content-Length` prechecks.
+
 If anything in this file conflicts with the `Makefile` or the Developer Guide, the `Makefile` and the documentation win. When unsure, **ask** for clarification before proceeding.
 
-## Agent Tips 
+## Agent Quick Tips (Do This)
 
-### Backend Development
+### Testing & Fixtures
 
-The following conventions summarize the insights gained when adding new configuration options, API endpoints, and related tests. Follow these conventions unless a maintainer requests an exception.
+- Go tests live next to their sources (`path/to/pkg/<file>_test.go`); group related cases as `t.Run(...)` sub-tests to keep table-driven coverage readable.
+- Prefer focused `go test` runs for speed (`go test ./internal/<pkg> -run <Name> -count=1`, `go test ./internal/commands -run <Name> -count=1`) and avoid `./...` unless you need the entire suite.
+- Heavy packages such as `internal/entity` and `internal/photoprism` run migrations and fixtures; expect 30–120s on first run and narrow with `-run` to keep iterations low.
+- For CLI-driven tests, wrap commands with `RunWithTestContext(cmd, args)` so `urfave/cli` cannot exit the process, and assert CLI output with `assert.Contains`/regex because `show` reports quote strings.
+- In `internal/photoprism` tests, rely on `photoprism.Config()` for runtime-accurate behavior; only build a new config if you replace it via `photoprism.SetConfig`.
+- Generate identifiers with `rnd.GenerateUID(entity.ClientUID)` for OAuth client IDs and `rnd.UUIDv7()` for node UUIDs; treat `node.uuid` as required in responses.
+- Shared fixtures live under `storage/testdata`; `NewTestConfig("<pkg>")` already calls `InitializeTestData()`, but call `c.InitializeTestData()` (and optionally `c.AssertTestData(t)`) when you construct custom configs so originals/import/cache/temp exist. `InitializeTestData()` clears old data, downloads fixtures if needed, then calls `CreateDirectories()`.
+- For slimmer tests that only need config objects, prefer the new helpers in `internal/config/test.go`: `NewMinimalTestConfig(t.TempDir())` when no database is needed, or `NewMinimalTestConfigWithDb("<pkg>", t.TempDir())` to spin up an isolated SQLite schema without seeding all fixtures.
+- When you need illustrative credentials (join tokens, client IDs/secrets, etc.), reuse the shared `Example*` constants (see `internal/service/cluster/examples.go`) so tests, docs, and examples stay consistent.
 
-- Config precedence and new options
-  - Global precedence: `options.yml` overrides CLI flags and environment variables, if present. Don’t special‑case a single option.
-  - Adding a new option:
-    - Add a field to `internal/config/options.go` with `yaml:"…"` and a `flag:"…"` tag.
-    - Register a CLI flag and env mapping in `internal/config/flags.go` (use `EnvVars(...)`).
-    - Expose a getter on `*config.Config` in the relevant file (e.g., cluster options in `config_cluster.go`).
-    - Add name/value to `rows` in `*config.Report()`, after the same option as in `internal/config/options.go` for `photoprism show config` to report it (obfuscate passwords with `*`).
-    - If the value must persist (e.g., a generated UUID), write it back to `options.yml` using a focused helper that merges keys.
-    - Tests: cover CLI/env/file precedence and persistence. When tests need a new flag, add it to `CliTestContext` in `internal/config/test.go`.
-  - Example: `PortalUUID` precedence = `options.yml` → CLI/env (`--portal-uuid` / `PHOTOPRISM_PORTAL_UUID`) → generate UUIDv4 and persist.
-  - CLI flag precedence: when you need to favor an explicit CLI flag over defaults, check `c.cliCtx.IsSet("<flag>")` before applying additional precedence logic.
-  - Persisting generated options: when writing to `options.yml`, set `c.options.OptionsYaml = filepath.Join(c.ConfigPath(), "options.yml")` and reload the file to keep in‑memory
+### Roles & ACL
 
-- Database access
-  - The app uses GORM v1. Don’t use `WithContext`; for executing raw SQL, prefer `db.Raw(stmt).Scan(&nop)`.
-  - When provisioning MariaDB/MySQL objects, quote identifiers with backticks and limit the character set; avoid building identifiers from untrusted input.
-  - Reuse `conf.Db()` and `conf.Database*()` getters; reject unsupported drivers early with a clear error.
+- Map roles via the shared tables: users through `acl.ParseRole(s)` / `acl.UserRoles[...]`, clients through `acl.ClientRoles[...]`.
+- Treat `RoleAliasNone` ("none") and an empty string as `RoleNone`; no caller-specific overrides.
+- Default unknown client roles to `RoleClient`; `acl.ParseRole` already handles `0/false/nil` as none for users.
+- Build CLI role help from `Roles.CliUsageString()` (e.g., `acl.ClientRoles.CliUsageString()`); never hand-maintain role lists.
+- When checking JWT/client scopes, use the shared helpers (`acl.ScopePermits` / `acl.ScopeAttrPermits`) instead of hand-written parsing.
 
-- Rate limiting
-  - Reuse the existing limiter in `internal/server/limiter` (e.g., `limiter.Auth` / `limiter.Login`).
-  - For 429s, use `limiter.AbortJSON(c)` when applicable; avoid creating new limiter stacks.
+### Import/Index
 
-- API handlers
-  - Use existing helpers: `api.ClientIP(c)`, `header.BearerToken(c)`, `Abort*` functions for errors.
-  - Compare secrets/tokens using constant‑time compare; don’t log secrets.
-  - Set `Cache-Control: no-store` on responses containing secrets.
-  - Register new routes in `internal/server/routes.go`. Don’t edit `swagger.json` directly—run `make swag` to regenerate.
-  - Portal mode: set `PHOTOPRISM_NODE_TYPE=portal` and `PHOTOPRISM_PORTAL_TOKEN`.
-  - Pagination defaults: for new list endpoints, prefer `count` default 100 (max 1000) and `offset` ≥ 0; document both in Swagger and validate bounds in handlers.
-  - Document parameters explicitly in Swagger annotations (path, query, and body) so `make swag` produces accurate docs.
-  - Swagger: `make fmt-go swag-fmt && make swag` after adding or changing API annotations.
-  - Focused tests: `go test ./internal/api -run Cluster -count=1` (or limit to the package you changed).
+- ImportWorker may skip files if an identical file already exists (duplicate detection). Use unique copies or assert DB rows after ensuring a non‑duplicate destination.
+- Mixed roots: when testing related files, keep `ExamplesPath()/ImportPath()/OriginalsPath()` consistent so `RelatedFiles` and `AllowExt` behave as expected.
 
-- Registry & secrets
-  - Store portal/node registry data under `conf.PortalConfigPath()/nodes/` as YAML with file mode `0600`.
-  - Keep node secrets out of logs and omit them from JSON responses unless explicitly returned on creation/rotation.
+### CLI Usage & Assertions
 
-- Testing patterns
-  - Use `t.TempDir()` for isolated config paths and files. After changing `ConfigPath` post‑construction, reload `options.yml` into `c.options` if needed.
-  - Prefer small, focused unit tests; use existing test helpers (`NewConfig`, `CliTestContext`, etc.).
-  - API tests: use `NewApiTest()`, `PerformRequest*`, `AuthenticateAdmin` / `AuthenticateUser`, and `OAuthToken` for client-scope scenarios.
-  - Permissions: cover public=false (401), CDN headers (403), admin access (200), and client tokens with insufficient scope (403).
-  - Auth mode in tests: use `conf.SetAuthMode(config.AuthModePasswd)` (and defer restore) instead of flipping `Options().Public`; this toggles related internals used by tests.
-  - Fixtures caveat: user fixtures often have admin role; for negative permission tests, prefer OAuth client tokens with limited scope rather than relying on a non‑admin user.
-  
-- Known tooling constraints
-  - Python may not be available in the dev container; prefer `apply_patch`, Go, or Make targets over ad‑hoc scripts.
-  - `make swag` may fetch modules; ensure network availability in CI before running.
+- Wrap CLI tests in `RunWithTestContext(cmd, args)` so `urfave/cli` cannot exit the process; assert quoted `show` output with `assert.Contains`/regex for the trailing ", or <last>" rule.
+- Prefer `--json` responses for automation. `photoprism show commands --json [--nested]` exposes the tree view (add `--all` for hidden entries).
+- Use `internal/commands/catalog` to inspect commands/flags without running the binary; when validating large JSON docs, marshal DTOs via `catalog.BuildFlat/BuildNode` instead of parsing CLI stdout.
+- Expect `show` commands to return arrays of snake_case rows, except `photoprism show config`, which yields `{ sections: [...] }`, and the `config-options`/`config-yaml` variants, which flatten to a top-level array.
+
+### API & Config Changes
+
+- Respect precedence: `options.yml` overrides CLI/env values, which override defaults. When adding a new option, update `internal/config/options.go` (yaml/flag tags), register it in `internal/config/flags.go`, expose a getter, surface it in `*config.Report()`, and write generated values back to `options.yml` by setting `c.options.OptionsYaml` before persisting. Use `CliTestContext` in `internal/config/test.go` to exercise new flags.
+- When touching configuration in Go code, use the public accessors on `*config.Config` (e.g. `Config.JWKSUrl()`, `Config.SetJWKSUrl()`, `Config.ClusterUUID()`) instead of mutating `Config.Options()` directly; reserve raw option tweaks for test fixtures only.
+- Logging: use the shared logger (`event.Log`) via the package-level `log` variable (see `internal/auth/jwt/logger.go`) instead of direct `fmt.Print*` or ad-hoc loggers.
+- Cluster registry tests (`internal/service/cluster/registry`) currently rely on a full test config because they persist `entity.Client` rows. They run migrations and seed the SQLite DB, so they are intentionally slow. If you refactor them, consider sharing a single `config.TestConfig()` across subtests or building a lightweight schema harness; do not swap to the minimal config helper unless the tests stop touching the database.
+- Favor explicit CLI flags: check `c.cliCtx.IsSet("<flag>")` before overriding user-supplied values, and follow the `ClusterUUID` pattern (`options.yml` → CLI/env → generated UUIDv4 persisted).
+- Database helpers: reuse `conf.Db()` / `conf.Database*()`, avoid GORM `WithContext`, quote MySQL identifiers, and reject unsupported drivers early.
+- Handler conventions: reuse limiter stacks (`limiter.Auth`, `limiter.Login`) and `limiter.AbortJSON` for 429s, lean on `api.ClientIP`, `header.BearerToken`, and `Abort*` helpers, compare secrets with constant time checks, set `Cache-Control: no-store` on sensitive responses, and register routes in `internal/server/routes.go`. For new list endpoints default `count=100` (max 1000) and `offset≥0`, document parameters explicitly, and set portal mode via `PHOTOPRISM_NODE_ROLE=portal` plus `PHOTOPRISM_JOIN_TOKEN` when needed.
+- Swagger & docs: annotate only routed handlers in `internal/api/*.go`, use full `/api/v1/...` paths, skip helpers, and regenerate docs with `make fmt-go swag-fmt swag` or `make swag-json` (which also strips duplicate `time.Duration` enums). When iterating, target packages with `go test ./internal/api -run Cluster -count=1` or similarly scoped runs.
+- Testing helpers: isolate config paths with `t.TempDir()`, reuse `NewConfig`, `CliTestContext`, and `NewApiTest()` harnesses, authenticate via `AuthenticateAdmin`, `AuthenticateUser`, or `OAuthToken`, toggle auth with `conf.SetAuthMode(config.AuthModePasswd)`, and prefer OAuth client tokens over non-admin fixtures for negative permission checks.
+- Registry data and secrets: store portal/node registry files under `conf.PortalConfigPath()/nodes/` with mode `0600`, keep secrets out of logs, and only return them on creation/rotation flows.
+
+### Formatting (Go)
+
+- Go is formatted by `gofmt` and uses tabs. Do not hand-format indentation.
+- Always run after edits: `make fmt-go` (gofmt + goimports).
+
+### API Shape Checklist
+
+- When renaming or adding fields:
+  - Update DTOs in `internal/service/cluster/response.go` and any mappers.
+  - Update handlers and regenerate Swagger: `make fmt-go swag-fmt swag`.
+  - Update tests (search/replace old field names) and examples in `specs/`.
+  - Quick grep: `rg -n 'oldField|newField' -S` across code, tests, and specs.
+
+### API/CLI Tests: Known Pitfalls
+
+- Gin routes: Register `CreateSession(router)` once per test router; reusing it twice panics on duplicate route.
+- CLI commands: Some commands defer `conf.Shutdown()` or emit signals that close the DB. The harness re‑opens DB before each run, but avoid invoking `start` or emitting signals in unit tests.
+- Signals: `internal/commands/start.go` waits on `process.Signal`; calling `process.Shutdown()/Restart()` can close DB. Prefer not to trigger signals in tests.
+
+### Download CLI Workbench (yt-dlp, remux, importer)
+
+- Code anchors
+  - CLI flags and examples: `internal/commands/download.go`
+  - Core implementation (testable): `internal/commands/download_impl.go`
+  - yt-dlp helpers and arg wiring: `internal/photoprism/dl/*` (`options.go`, `info.go`, `file.go`, `meta.go`)
+  - Importer entry point: `internal/photoprism/get/import.go`; options: `internal/photoprism/import_options.go`
+
+- Quick test runs (fast feedback)
+  - yt-dlp package: `go test ./internal/photoprism/dl -run 'Options|Created|PostprocessorArgs' -count=1`
+  - CLI command: `go test ./internal/commands -run 'DownloadImpl|HelpFlags' -count=1`
+
+- FFmpeg-less tests
+  - In tests: set `c.Options().FFmpegBin = "/bin/false"` and `c.Settings().Index.Convert = false` to avoid ffmpeg dependencies when not validating remux.
+
+- Stubbing yt-dlp (no network)
+  - Use a tiny shell script that:
+    - prints minimal JSON for `--dump-single-json`
+    - creates a file and prints its path when `--print` is requested
+  - Harness env vars (supported by our tests):
+    - `YTDLP_ARGS_LOG` — append final args for assertion
+    - `YTDLP_OUTPUT_FILE` — absolute file path to create for `--print`
+    - `YTDLP_DUMMY_CONTENT` — file contents to avoid importer duplicate detection between tests
+
+- Remux policy and metadata
+  - Pipe method: PhotoPrism remux (ffmpeg) always embeds title/description/created.
+  - File method: yt‑dlp writes files; we pass `--postprocessor-args 'ffmpeg:-metadata creation_time=<RFC3339>'` so imports get `Created` even without local remux (fallback from `upload_date`/`release_date`).
+  - Default remux policy: `auto`; use `always` for the most complete metadata (chapters, extended tags).
+
+- Testing workflow: lean on the focused commands above; if importer dedupe kicks in, vary bytes with `YTDLP_DUMMY_CONTENT` or adjust `dest`, and remember `internal/photoprism` is heavy so validate downstream packages first.
+
+### Sessions & Redaction (building sessions in tests)
+
+- Admin session (full view): `AuthenticateAdmin(app, router)`.
+- User session: Create a non‑admin test user (role=guest), set a password, then `AuthenticateUser`.
+- Client session (redacted internal fields; `siteUrl` visible):
+  ```go
+  s, _ := entity.AddClientSession("test-client", conf.SessionMaxAge(), "cluster", authn.GrantClientCredentials, nil)
+  token := s.AuthToken()
+  r := AuthenticatedRequest(app, http.MethodGet, "/api/v1/cluster/nodes", token)
+  ```
+  Admins see `advertiseUrl` and `database`; client/user sessions don’t. `siteUrl` is safe to show to all roles.
+
+### Preflight Checklist
+
+- `go build ./...`
+- `make fmt-go swag-fmt swag`
+- `go test ./internal/service/cluster/registry -count=1`
+- `go test ./internal/api -run 'Cluster' -count=1`
+- `go test ./internal/commands -run 'ClusterRegister|ClusterNodesRotate' -count=1`
+- Tooling constraints: `make swag` may fetch modules, so confirm network access before running it.
+
+### Cluster Operations
+
+- Keep bootstrap code decoupled: avoid importing `internal/service/cluster/node/*` from `internal/config` or the cluster root, let nodes talk to the Portal over HTTP(S), and rely on constants from `internal/service/cluster/const.go`.
+- Config init order: load `options.yml` (`c.initSettings()`), run `EarlyExt().InitEarly(c)`, connect/register the DB, then invoke `Ext().Init(c)`.
+- Theme endpoint: `GET /api/v1/cluster/theme` streams a zip from `conf.ThemePath()`; only reinstall when `app.js` is missing and always use the header helpers in `pkg/service/http/header`.
+- Registration flow: send `rotate=true` only for MySQL/MariaDB nodes without credentials, treat 401/403/404 as terminal, include `clientId` + `clientSecret` when renaming an existing node, and persist only newly generated secrets or DB settings.
+- Registry & DTOs: use the client-backed registry (`NewClientRegistryWithConfig`)—the file-backed version is legacy—and treat migration as complete only after swapping callsites, building, and running focused API/CLI tests. Nodes are keyed by UUID v7 (`/api/v1/cluster/nodes/{uuid}`), the registry interface stays UUID-first (`Get`, `FindByNodeUUID`, `FindByClientID`, `RotateSecret`, `DeleteAllByUUID`), CLI lookups resolve `uuid → clientId → name`, and DTOs normalize `database.{name,user,driver,rotatedAt}` while exposing `clientSecret` only during creation/rotation. `nodes rm --all-ids` cleans duplicate client rows, admin responses may include `advertiseUrl`/`database`, client/user sessions stay redacted, registry files live under `conf.PortalConfigPath()/nodes/` (mode 0600), and `ClientData` no longer stores `NodeUUID`.
+- Provisioner & DSN: database/user names use UUID-based HMACs (`photoprism_d<hmac11>`, `photoprism_u<hmac11>`); `BuildDSN` accepts a `driver` but falls back to MySQL format with a warning when unsupported.
+- If we add Postgres provisioning support, extend `BuildDSN` and `provisioner.DatabaseDriver` handling, add validations, and return `driver=postgres` consistently in API/CLI.
+- Testing: exercise Portal endpoints with `httptest`, guard extraction paths with `pkg/fs.Unzip` size caps, and expect admin-only fields to disappear when authenticated as a client/user session.

+PhotoPrism — Backend CODEMAP
+
+**Last Updated:** September 24, 2025
+
+Purpose
+- Give agents and contributors a fast, reliable map of where things live and how they fit together, so you can add features, fix bugs, and write tests without spelunking.
+- Sources of truth: prefer Makefile targets and the Developer Guide linked in AGENTS.md.
+
+Quick Start
+- Inside dev container (recommended):
+  - Install deps: `make dep`
+  - Build backend: `make build-go`
+  - Run server: `./photoprism start`
+  - Open: http://localhost:2342/ or https://app.localssl.dev/ (Traefik required)
+- On host (manages Docker):
+  - Build image: `make docker-build`
+  - Start services: `docker compose up -d`
+  - Logs: `docker compose logs -f --tail=100 photoprism`
+
+Executables & Entry Points
+- CLI app (binary name across docs/images is `photoprism`):
+  - Main: `cmd/photoprism/photoprism.go`
+  - Commands registry: `internal/commands/commands.go` (array `commands.PhotoPrism`)
+  - Catalog helpers: `internal/commands/catalog` (DTOs and builders to enumerate commands/flags; Markdown renderer)
+- Web server:
+  - Startup: `internal/commands/start.go` → `server.Start` (starts HTTP(S), workers, session cleanup)
+  - HTTP server: `internal/server/start.go` (compression, security, healthz, readiness, TLS/AutoTLS/unix socket)
+  - Routes: `internal/server/routes.go` (registers all v1 API groups + UI, WebDAV, sharing, .well-known)
+  - API group: `APIv1 = router.Group(conf.BaseUri("/api/v1"), Api(conf))`
+
+High-Level Package Map (Go)
+- `internal/api` — Gin handlers and Swagger annotations; only glue, no business logic
+- `internal/commands/catalog` — DTOs (App, Command, Flag, Node), builders (BuildFlat/BuildNode, CommandInfo, FlagsToCatalog), and a templated Markdown renderer (RenderMarkdown) for the CLI commands catalog. Depends only on `urfave/cli/v2` and stdlib.
+- `internal/server` — HTTP server, middleware, routing, static/ui/webdav
+- `internal/config` — configuration, flags/env/options, client config, DB init/migrate
+- `internal/entity` — GORM v1 models, queries, search helpers, migrations
+- `internal/photoprism` — core domain logic (indexing, import, faces, thumbnails, cleanup)
+- `internal/workers` — background schedulers (index, vision, sync, meta, backup)
+- `internal/auth` — ACL, sessions, OIDC
+- `internal/service` — cluster/portal, maps, hub, webdav
+- `internal/event` — logging, pub/sub, audit
+- `internal/ffmpeg`, `internal/thumb`, `internal/meta`, `internal/form`, `internal/mutex` — media, thumbs, metadata, forms, coordination
+- `pkg/*` — reusable utilities (must never import from `internal/*`), e.g. `pkg/fs`, `pkg/log`, `pkg/service/http/header`
+
+HTTP API
+- Handlers live in `internal/api/*.go` and are registered in `internal/server/routes.go`.
+- Annotate new endpoints in handler files; generate docs with: `make fmt-go swag-fmt && make swag`.
+- Do not edit `internal/api/swagger.json` by hand.
+- Swagger notes:
+  - Use full `/api/v1/...` in every `@Router` annotation (match the group prefix).
+  - Annotate only public handlers; skip internal helpers to avoid stray generic paths.
+  - `make swag-json` runs a stabilization step (`swaggerfix`) removing duplicated enums for `time.Duration`; API uses integer nanoseconds for durations.
+- Common groups in `routes.go`: sessions, OAuth/OIDC, config, users, services, thumbnails, video, downloads/zip, index/import, photos/files/labels/subjects/faces, batch ops, cluster, technical (metrics, status, echo).
+
+Configuration & Flags
+- Options struct: `internal/config/options.go` with `yaml:"…"` (for `defaults.yml`/`options.yml`), `json:"…"` (clients/API), and `flag:"…"` (CLI flags/env) tags.
+  - For secrets/internals: `json:"-"` disables JSON processing to prevent values from being exposed through the API (see `internal/api/config_options.go`).
+  - If needed: `yaml:"-"` disables YAML processing; `flag:"-"` prevents `ApplyCliContext()` from assigning CLI values (flags/env variables) to a field, without affecting the flags in `internal/config/flags.go`.
+  - Annotations may include edition tags like `tags:"plus,pro"` to control visibility (see `internal/config/options_report.go` logic).
+- Global flags/env: `internal/config/flags.go` (`EnvVars(...)`)
+  - Available flags/env: `internal/config/cli_flags_report.go` + `internal/config/report_sections.go` → surfaced by `photoprism show config-options --md/--json`
+  - YAML options mapping: `internal/config/options_report.go` + `internal/config/report_sections.go` → surfaced by `photoprism show config-yaml --md/--json`
+  - Report current values: `internal/config/report.go` → surfaced by `photoprism show config` (alias `photoprism config --md`).
+  - CLI commands catalog: `internal/commands/show_commands.go` → surfaced by `photoprism show commands` (Markdown by default; `--json` alternative; `--nested` optional tree; `--all` includes hidden commands/flags; nested `help` subcommands omitted).
+- Precedence: `defaults.yml` < CLI/env < `options.yml` (global options rule). See Agent Tips in `AGENTS.md`.
+- Getters are grouped by topic, e.g. DB in `internal/config/config_db.go`, server in `config_server.go`, TLS in `config_tls.go`, etc.
+- Client Config (read-only)
+  - Endpoint: GET `/api/v1/config` (see `internal/api/api_client_config.go`).
+  - Assembly: Built from `internal/config/client_config.go` (not a direct serialization of Options) plus extension values registered via `config.Register` in `internal/config/extensions.go`.
+  - Updates: Back-end calls `UpdateClientConfig()` to publish "config.updated" over websockets after changes (see `internal/api/config_options.go` and `internal/api/config_settings.go`).
+  - ACL/mode aware: Values are filtered by user/session and may differ for public vs. authenticated users.
+  - Don’t expose secrets: Treat it as client-visible; avoid sensitive data. To add fields, extend client values via `config.Register` rather than exposing Options directly.
+  - Refresh cadence: The web UI (non‑mobile) also polls for updates every 10 minutes via `$config.update()` in `frontend/src/app.js`, complementing the websocket push.
+
+Database & Migrations
+- Driver: GORM v1 (`github.com/jinzhu/gorm`). No `WithContext`. Use `db.Raw(stmt).Scan(&nop)` for raw SQL.
+- Entities and helpers: `internal/entity/*.go` and subpackages (`query`, `search`, `sortby`).
+- Migrations engine: `internal/entity/migrate/*` — run via `config.MigrateDb()`; CLI: `photoprism migrate` / `photoprism migrations`.
+- DB init/migrate flow: `internal/config/config_db.go` chooses driver/DSN, sets `gorm:table_options`, then `entity.InitDb(migrate.Opt(...))`.
+
+AuthN/Z & Sessions
+- Session model and cache: `internal/entity/auth_session*` and `internal/auth/session/*` (cleanup worker).
+- ACL: `internal/auth/acl/*` — roles, grants, scopes; use constants; avoid logging secrets, compare tokens constant‑time; for scope checks use `acl.ScopePermits` / `ScopeAttrPermits` instead of rolling your own parsing.
+- OIDC: `internal/auth/oidc/*`.
+
+Media Processing
+- Thumbnails: `internal/thumb/*` and helpers in `internal/photoprism/mediafile_thumbs.go`.
+- Metadata: `internal/meta/*`.
+- FFmpeg integration: `internal/ffmpeg/*`.
+
+Background Workers
+- Scheduler and workers: `internal/workers/*.go` (index, vision, meta, sync, backup, share); started from `internal/commands/start.go`.
+- Auto indexer: `internal/workers/auto/*`.
+
+Cluster / Portal
+- Node types: `internal/service/cluster/const.go` (`cluster.RoleInstance`, `cluster.RolePortal`, `cluster.RoleService`).
+- Node bootstrap & registration: `internal/service/cluster/node/*` (HTTP to Portal; do not import Portal internals).
+- Registry/provisioner: `internal/service/cluster/registry/*`, `internal/service/cluster/provisioner/*`.
+- Theme endpoint (server): GET `/api/v1/cluster/theme`; client/CLI installs theme only if missing or no `app.js`.
+- See specs cheat sheet: `specs/portal/README.md`.
+
+Logging & Events
+- Logger and event hub: `internal/event/*`; `event.Log` is the shared logger.
+- HTTP headers/constants: `pkg/service/http/header/*` — always prefer these in handlers and tests.
+
+Server Startup Flow (happy path)
+1) `photoprism start` (CLI) → `internal/commands/start.go`
+2) Config init, DB init/migrate, session cleanup worker
+3) `internal/server/start.go` builds Gin engine, middleware, API group, templates
+4) `internal/server/routes.go` registers UI, WebDAV, sharing, well‑known, and all `/api/v1/*` routes
+5) Workers and auto‑index start; health endpoints `/livez`, `/readyz` available
+
+Common How‑Tos
+- Add a CLI command
+  - Create `internal/commands/<name>.go` with a `*cli.Command`
+  - Add it to `PhotoPrism` in `internal/commands/commands.go`
+  - Tests: prefer `RunWithTestContext` from `internal/commands/commands_test.go` to avoid `os.Exit`
+
+- Add a REST endpoint
+  - Create handler in `internal/api/<area>.go` with Swagger annotations
+  - Register it in `internal/server/routes.go`
+  - Use helpers: `api.ClientIP(c)`, `header.BearerToken(c)`, `Abort*` functions
+  - Validate pagination bounds (default `count=100`, max `1000`, `offset>=0`) for list endpoints
+  - Run `make fmt-go swag-fmt && make swag`; keep docs accurate
+  - Tests: `go test ./internal/api -run <Name>` and focused helpers (`NewApiTest()`, `PerformRequest*`)
+
+- Add a config option
+  - Add field with tags to `internal/config/options.go`
+  - Register CLI flag/env in `internal/config/flags.go` via `EnvVars(...)`
+  - Expose a getter (e.g., in `config_server.go` or topic file)
+  - Append to `rows` in `*config.Report()` after the same option as in `options.go`
+  - If value must persist, write back to `options.yml` and reload into memory
+  - Tests: cover CLI/env/file precedence (see `internal/config/test.go` helpers)
+
+- Touch the DB schema
+  - Use GORM auto-migration, or add a custom migration in `internal/entity/migrate/<dialect>/...` and run `go generate` or `make generate` (runs `go generate` for all packages) 
+  - Bump/review version gates in `migrate.Version` usage via `config_db.go`
+  - Tests: run against SQLite by default; for MySQL cases, gate appropriately
+
+Testing
+- Full suite: `make test` (frontend + backend). Backend only: `make test-go`.
+- Focused packages: `go test ./internal/<pkg> -run <Name>`.
+- CLI tests: `PHOTOPRISM_CLI=noninteractive` or pass `--yes` to avoid prompts; use `RunWithTestContext` to prevent `os.Exit`.
+- SQLite DSN in tests is per‑suite (not empty). Clean up files if you capture the DSN.
+- Frontend unit tests via Vitest are separate; see `frontend/CODEMAP.md`.
+
+Security & Hot Spots (Where to Look)
+- Zip extraction (path traversal prevention): `pkg/fs/zip.go`
+  - Uses `safeJoin` to reject absolute/volume paths and `..` traversal; enforces per-file and total size limits.
+  - Tests: `pkg/fs/zip_extra_test.go` cover abs/volume/.. cases and limits.
+- Force-aware Copy/Move and truncation-safe writes:
+  - App helpers: `internal/photoprism/mediafile.go` (`MediaFile.Copy/Move` with `force`).
+  - Utils: `pkg/fs/copy.go`, `pkg/fs/move.go` (use `O_TRUNC` to avoid trailing bytes).
+- FFmpeg command builders and encoders:
+  - Core: `internal/ffmpeg/transcode_cmd.go`, `internal/ffmpeg/remux.go`.
+  - Encoders (string builders only): `internal/ffmpeg/{apple,intel,nvidia,vaapi,v4l}/avc.go`.
+  - Tests guard HW runs with `PHOTOPRISM_FFMPEG_ENCODER`; otherwise assert command strings and negative paths.
+- libvips thumbnails:
+  - Pipeline: `internal/thumb/vips.go` (VipsInit, VipsRotate, export params).
+  - Sizes & names: `internal/thumb/sizes.go`, `internal/thumb/names.go`, `internal/thumb/filter.go`.
+
+- Safe HTTP downloader:
+  - Shared utility: `pkg/service/http/safe` (`Download`, `Options`).
+  - Protections: scheme allow‑list (http/https), pre‑DNS + per‑redirect hostname/IP validation, final peer IP check, size and timeout enforcement, temp file `0600` + rename.
+  - Avatars: wrapper `internal/thumb/avatar.SafeDownload` applies stricter defaults (15s, 10 MiB, `AllowPrivate=false`, image‑focused `Accept`).
+  - Tests: `go test ./pkg/service/http/safe -count=1` (includes redirect SSRF cases); avatars: `go test ./internal/thumb/avatar -count=1`.
+
+Performance & Limits
+- Prefer existing caches/workers/batching as per Makefile and code.
+- When adding list endpoints, default `count=100` (max `1000`); set `Cache-Control: no-store` for secrets.
+
+Conventions & Rules of Thumb
+- Respect package boundaries: code in `pkg/*` must not import `internal/*`.
+- Prefer constants/helpers from `pkg/service/http/header` over string literals.
+- Never log secrets; compare tokens constant‑time.
+- Don’t import Portal internals from cluster instance/service bootstraps; use HTTP.
+- Prefer small, hermetic unit tests; isolate filesystem paths with `t.TempDir()` and env like `PHOTOPRISM_STORAGE_PATH`.
+- Cluster nodes: identify by UUID v7 (internally stored as `NodeUUID`; exposed as `uuid` in API/CLI). The OAuth client ID (`NodeClientID`, exposed as `clientId`) is for OAuth only. Registry lookups and CLI commands accept uuid, clientId, or DNS‑label name (priority in that order).
+
+Filesystem Permissions & io/fs Aliasing
+- Use `github.com/photoprism/photoprism/pkg/fs` permission variables when creating files/dirs:
+  - `fs.ModeDir` (0o755 with umask), `fs.ModeFile` (0o644 with umask), `fs.ModeConfigFile` (0o664), `fs.ModeSecretFile` (0o600), `fs.ModeBackupFile` (0o600).
+- Do not use stdlib `io/fs` mode bits as permission arguments. When importing stdlib `io/fs`, alias it (`iofs`/`gofs`) to avoid `fs.*` collisions with our package.
+- Prefer `filepath.Join` for filesystem paths across platforms; use `path.Join` for URLs only.
+
+Cluster Registry & Provisioner Cheatsheet
+- UUID‑first everywhere: API paths `{uuid}`, Registry `Get/Delete/RotateSecret` by UUID; explicit `FindByClientID` exists for OAuth.
+- Node/DTO fields: `uuid` required; `clientId` optional; database metadata includes `driver`.
+- Provisioner naming (no slugs):
+  - database: `photoprism_d<hmac11>`
+  - username: `photoprism_u<hmac11>`
+  HMAC is base32 of ClusterUUID+NodeUUID; drivers currently `mysql|mariadb`.
+- DSN builder: `BuildDSN(driver, host, port, user, pass, name)`; warns and falls back to MySQL format for unsupported drivers.
+- Go tests live beside sources: for `path/to/pkg/<file>.go`, add tests in `path/to/pkg/<file>_test.go` (create if missing). For the same function, group related cases as `t.Run(...)` sub-tests (table-driven where helpful).
+- Public API and internal registry DTOs use normalized field names:
+  - `database` (not `db`) with `name`, `user`, `driver`, `rotatedAt`.
+  - Node-level rotation timestamps use `rotatedAt`.
+  - Registration returns `secrets.clientSecret`; the CLI persists it under config `NodeClientSecret`.
+  - Admin responses may include `advertiseUrl` and `database`; non-admin responses are redacted by default.
+
+Frequently Touched Files (by topic)
+- CLI wiring: `cmd/photoprism/photoprism.go`, `internal/commands/commands.go`
+- Server: `internal/server/start.go`, `internal/server/routes.go`, middleware in `internal/server/*.go`
+- API handlers: `internal/api/*.go` (plus `docs.go` for package docs)
+- Config: `internal/config/*` (`flags.go`, `config_db.go`, `config_server.go`, `options.go`)
+- Entities & queries: `internal/entity/*.go`, `internal/entity/query/*`
+- Migrations: `internal/entity/migrate/*`
+- Workers: `internal/workers/*`
+- Cluster: `internal/service/cluster/*`
+- Headers: `pkg/service/http/header/*`
+
+Downloads (CLI) & yt-dlp helpers
+- CLI command & core:
+  - `internal/commands/download.go` (flags, defaults, examples)
+  - `internal/commands/download_impl.go` (testable implementation used by CLI)
+- yt-dlp wrappers:
+  - `internal/photoprism/dl/options.go` (arg wiring; `FFmpegPostArgs` hook for `--postprocessor-args`)
+  - `internal/photoprism/dl/info.go` (metadata discovery)
+  - `internal/photoprism/dl/file.go` (file method with `--output`/`--print`)
+  - `internal/photoprism/dl/meta.go` (`CreatedFromInfo` fallback; `RemuxOptionsFromInfo`)
+- Importer:
+  - `internal/photoprism/get/import.go` (work pool)
+  - `internal/photoprism/import_options.go` (`ImportOptionsMove/Copy`)
+- Testing hints:
+  - Fast loops: `go test ./internal/photoprism/dl -run 'Options|Created|PostprocessorArgs' -count=1`
+  - CLI only: `go test ./internal/commands -run 'DownloadImpl|HelpFlags' -count=1`
+  - Disable ffmpeg when not needed: set `FFmpegBin = "/bin/false"`, `Settings.Index.Convert=false` in tests.
+  - Stub yt-dlp: shell script that prints JSON for `--dump-single-json`, creates a file and prints path for `--print`.
+  - Avoid importer dedup: vary file bytes (e.g., `YTDLP_DUMMY_CONTENT`) or dest.
+
+Useful Make Targets (selection)
+- `make help` — list targets
+- `make dep` — install Go/JS deps in container
+- `make build-go` — build backend
+- `make test-go` — backend tests (SQLite)
+- `make swag` — generate Swagger JSON in `internal/api/swagger.json`

+PhotoPrism — Frontend CODEMAP
+
+Purpose
+- Help agents and contributors navigate the Vue 3 + Vuetify 3 app quickly and make safe changes.
+- Use Makefile targets and scripts in `frontend/package.json` as sources of truth.
+
+Quick Start
+- Build once: `make -C frontend build`
+- Watch for changes (inside dev container is fine):
+  - `make watch-js` from repo root, or
+  - `cd frontend && npm run watch`
+- Unit tests (Vitest): `make vitest-watch` / `make vitest-coverage` or `cd frontend && npm run test`
+
+Directory Map (src)
+- `src/app.vue` — root component; UI shell
+- `src/app.js` — app bootstrap: creates Vue app, installs Vuetify + plugins, configures router, mounts to `#app`
+- `src/app/routes.js` — all route definitions (guards, titles, meta)
+- `src/app/session.js` — `$config` and `$session` singletons wired from server-provided `window.__CONFIG__` and storage
+- `src/common/*` — framework-agnostic helpers: `$api` (Axios), `$notify`, `$view`, `$event` (PubSub), i18n (`gettext`), util, fullscreen, map utils, websocket
+- `src/component/*` — Vue components; `src/component/components.js` registers global components
+- `src/page/*` — route views (Albums, Photos, Places, Settings, Admin, Discover, Help, Login, etc.)
+- `src/model/*` — REST models; base `Rest` class (`model/rest.js`) wraps Axios CRUD for collections and entities
+- `src/options/*` — UI/theme options, formats, auth options
+- `src/css/*` — styles loaded by Webpack
+- `src/locales/*` — gettext catalogs; extraction/compile scripts in `package.json`
+
+Runtime & Plugins
+- Vue 3 + Vuetify 3 (`createVuetify`) with MDI icons; themes from `src/options/themes.js`
+- Router: Vue Router 4, history base at `$config.baseUri + "/library/"`
+- I18n: `vue3-gettext` via `common/gettext.js`; extraction with `npm run gettext-extract`, compile with `npm run gettext-compile`
+- HTML sanitization: `vue-3-sanitize` + `vue-sanitize-directive`
+- Tooltips: `floating-vue`
+- Video: HLS.js assigned to `window.Hls`
+- PWA: `@lcdp/offline-plugin/runtime` installs when `baseUri === ""`
+- WebSocket: `src/common/websocket.js` publishes `websocket.*` events, used by `$session` for client info
+
+HTTP Client
+- Axios instance: `src/common/api.js`
+  - Base URL: `window.__CONFIG__.apiUri` (or `/api/v1` in tests)
+  - Adds `X-Auth-Token`, `X-Client-Uri`, `X-Client-Version`
+  - Interceptors drive global progress notifications and token refresh via headers `X-Preview-Token`/`X-Download-Token`
+
+Auth, Session, and Config
+- `$session`: `src/common/session.js` — stores `X-Auth-Token` and `session.id` in storage; provides guards and default routes
+- `$config`: `src/common/config.js` — reactive view of server config and user settings; sets theme, language, limits; exposes `deny()` for feature flags
+- Route guards live in `src/app.js` (router `beforeEach`/`afterEach`) and use `$session` + `$config`
+
+Models (REST)
+- Base class: `src/model/rest.js` provides `search`, `find`, `save`, `update`, `remove` for concrete models (`photo`, `album`, `label`, `subject`, etc.)
+- Pagination headers used: `X-Count`, `X-Limit`, `X-Offset`
+
+Routing Conventions
+- Add pages under `src/page/<area>/...` and import them in `src/app/routes.js`
+- Set `meta.requiresAuth`, `meta.admin`, and `meta.settings` as needed
+- Use `meta.title` for translated titles; `router.afterEach` updates `document.title`
+
+Theming & UI
+- Themes: `src/options/themes.js` registered in Vuetify; default comes from `$config.values.settings.ui.theme`
+- Global components: register in `src/component/components.js` when they are broadly reused
+
+Testing
+- Vitest config: `frontend/vitest.config.js` (Vue plugin, alias map to `src/*`), `tests/vitest/**/*`
+- Run: `cd frontend && npm run test` (or `make test-js` from repo root)
+- Acceptance: TestCafe configs in `frontend/tests/acceptance`; run against a live server
+
+Build & Tooling
+- Webpack is used for bundling; scripts in `frontend/package.json`:
+  - `npm run build` (prod), `npm run build-dev` (dev), `npm run watch`
+  - Lint/format: `npm run lint`, `npm run fmt`
+  - Security scan: `npm run security:scan` (checks `--ignore-scripts` and forbids `v-html`)
+- Make targets (from repo root): `make build-js`, `make watch-js`, `make test-js`
+
+Common How‑Tos
+- Add a page
+  - Create `src/page/<name>.vue` (or nested directory)
+  - Add route in `src/app/routes.js` with `name`, `path`, `component`, and `meta`
+  - Use `$api` for data, `$notify` for UX, `$session` for guards
+
+- Add a REST model
+  - Create `src/model/<thing>.js` extending `Rest` and implement `static getCollectionResource()` + `static getModelName()`
+  - Use in pages/components for CRUD
+
+- Call a backend endpoint
+  - Use `$api.get/post/put/delete` from `src/common/api.js`
+  - For auth: `$session.setAuthToken(token)` sets header; router guards redirect to `login` when needed
+
+- Add translations
+  - Wrap strings with `$gettext(...)` / `$pgettext(...)`
+  - Extract: `npm run gettext-extract`; compile: `npm run gettext-compile`
+
+Conventions & Safety
+- Avoid `v-html`; use `v-sanitize` or `$util.sanitizeHtml()` (build enforces this)
+- Keep big components lazy if needed; split views logically under `src/page`
+- Respect aliases in `vitest.config.js` when importing (`app`, `common`, `component`, `model`, `options`, `page`)
+
+Frequently Touched Files
+- Bootstrap: `src/app.js`, `src/app.vue`
+- Router: `src/app/routes.js`
+- HTTP: `src/common/api.js`
+- Session/Config: `src/common/session.js`, `src/common/config.js`
+- Models: `src/model/rest.js` and concrete models (`photo.js`, `album.js`, ...)
+- Global components: `src/component/components.js`
+
+See Also
+- Backend CODEMAP at repo root (`CODEMAP.md`) for API and server internals
+- AGENTS.md for repo-wide rules and test tips
