 This repository contains the static Swedish web client for the AI-driven life simulator. The intended deployment is a small Nginx pod in the `ai-spel` namespace. The existing Rust service remains authoritative for accounts, game state, and all `/api/...` routes.
 
-The browser and API stay on the same public origin, `https://ai-spel.k3s.k0.nu`. The ingress routes `/` to this frontend service and routes `/api`, `/version`, and `/health` to the Rust service. That keeps the current server-side session cookie same-origin and avoids browser CORS configuration.
+After login, character creation and play use one dialogue history and one text input. The player writes a free biography, receives a temporary AI draft, can request revisions, and approves it by writing `godkänn`. The player then receives a proposed start world and place based on the biography. That draft can also be revised in dialogue and is saved only after a second explicit `godkänn`. Drafts stay in the browser until approval and are lost if the page is reloaded first. The backend creates the character and initializes the world only after their respective approvals.
+
+During play the UI has no persistent location, task, inventory, economy, status, or purchase panels. The player asks for information or writes an action in the same input. Rust validates state changes; the AI can only propose a typed intent. A direct request to travel may establish a new place and an encounter when Rust commits that movement.
+
+The dialogue also offers **Gör om senaste** and **Torrkör senaste**. Both resend the latest player action while leaving the previous dialogue turn out of the AI conversation context. “Gör om” processes a fresh, normal turn. “Torrkör” calls the narrator, generates and validates a temporary Luau rule when needed, and evaluates either that temporary rule or an approved stored rule. It rolls back the complete game transaction and does not save the player turn, AI trace, generated rule, event, ownership, or world progress. The reply identifies which rule was evaluated and marks a temporary rule as such.
+
+If the player asks to find or approach someone and no NPC is present, the direct dialogue scene may propose one person and an opening line. Rust creates that NPC only for the explicit request and commits the first exchange idempotently; a later turn continues the saved conversation. Clear requests about the current location are answered from its saved facts without asking the player to restate what they want to inspect.
+
+The separate `/admin` route provides an authenticated operations view for player search/profile/trace, NPC selection and editing, YAML prompt assets, generated Luau rules with validation results, runtime debug logging, and the append-only audit log. NPC editing covers identity and voice, typed profile fields plus future JSON properties, existing memory reconstructions, and owned items. The UI displays current position and commitments for context. Every NPC read and write goes through Rust, checks `accounts.is_admin=true`, validates domain limits, and writes an audit record in the same transaction as each mutation; the browser never connects directly to PostgreSQL. Profile and memory writes use expected-current values to detect stale edits. The Driftloggar view lets an administrator switch `debug=true` on or off without restarting pods; the setting is stored in PostgreSQL and propagated to running replicas. Verbose pod logs include request, AI-call, validation, and commit metadata but never raw player text, prompts, model responses, sessions, or secrets. Full protected prompt/provider exchanges remain in the audited player trace.
+
+The game is text- and dialogue-based and uses no images. Place descriptions include sound, smell, air/temperature, touch/surface, and spatial-orientation cues. Visible details may also be described in words, but are never required to understand the scene or play. The transcript is screen-reader announced. A clearly labeled **Skicka** button beside the microphone submits typed text; Enter also submits while Shift+Enter inserts a newline. Typed text, speech transcriptions, and the send button all use the same submission flow.
+
+Player-facing speech uses Piper TTS in WebAssembly in the browser after audio is activated by a user gesture. It reads game dialogue, onboarding, account responses, character and world creation, gameplay replies, in-game errors, and microphone disclosures; the `/admin` route is excluded. The audio is decoded and played through the Web Audio API, independently of `speechSynthesis`. The first unauthenticated visit keeps the introduction visible and it can be started with `Läs introduktionen`. New game replies are read automatically and the transcript remains available to screen readers and as text. Returning players hear the latest saved game reply when they reopen the game. The player can change speaking rate; narrator pitch is neutral and character pitch is varied consistently by voice identity. These preferences are stored in browser `localStorage`. If WebAssembly, model loading, or audio playback fails, the same content remains available as text and the dialogue offers a retry.
+
+The Piper engine, ONNX WebAssembly runtime, and all three Swedish medium voice models (Alma, Lisa, and NST) are served by the separate `ai-spel-static` Nginx service from same-origin `/static/piper-wasm-v1/`. Its own Gitea pipeline downloads pinned models, verifies sizes and hashes, and publishes a versioned image and Helm chart independently from frontend changes. The frontend's Piper adapter redirects the library's built-in model URLs to this static service; it does not request voice files from Hugging Face. Voice models are fetched on first use and cached in browser storage when supported. Dialogue text is synthesized on the device and is not sent to a TTS provider. Attribution is available at `/static/piper-wasm-v1/voices/ATTRIBUTION.txt`.
+
+The microphone button beside the text field uses Web Speech API when available and sends only its final Swedish transcript through the same submission path as typed text. Before its first use, the client explains that the browser may process audio through a provider-selected service; the game itself does not receive or store recordings, while the final transcript is saved as ordinary dialogue. Writing `röstinställningar` or saying `röstkommando alternativ` opens temporary voice controls in the dialogue. The player can adjust speaking rate and enable or disable short audio cues. Voice preferences are stored in browser `localStorage`.
+
+When a character or NPC is created, its saved voice identity is masculine, feminine, or neutral. The biography prompt only assigns masculine/feminine when the character is explicitly described that way; otherwise it uses neutral. Piper applies a stable, subtle pitch/rate profile per character, so a character keeps the same sound across visits. Narration always uses neutral pitch.
+
+System voice commands require the prefix `röstkommando`: `upprepa`, `avbryt`, `hjälp`, `alternativ`, or `paus`. Without the prefix, the same words remain ordinary dialogue. Speech recognition and synthesis are browser-dependent; release acceptance must record which real iPhone/Safari/VoiceOver and Android/Chrome/TalkBack combinations were actually checked.
+
+On iPhone and iPad, Safari requires a user gesture to unlock Web Audio. The frontend resumes the audio context during a trusted tap or key press and then reads generated replies automatically. Voice settings include **Testa ljudet**; if a game reply does not start, a **Läs senaste repliken** button appears in the dialogue. First use can take longer while the voice model downloads; progress and errors are announced in the dialogue. Actual iPhone/iPad playback remains a release acceptance check and must not be claimed until tested on a device.
+
+The browser and API stay on the same public origin, `https://ai-spel.k3s.k0.nu`. The ingress routes `/` to this frontend service and routes `/api`, `/graphql`, `/version`, and `/health` to the Rust service. Player dialogue is read through the authenticated, cursor-paginated GraphQL `dialogue(first, before)` query. Admin conversation traces use the audited `adminPlayerTrace(accountId, limit, offset)` GraphQL query. Writes remain explicit Rust command routes. That keeps the current server-side session cookie same-origin and avoids browser CORS configuration.
+
+The public footer displays the frontend, static-service, and API versions. It fetches `/static/version.json` without caching; the static service creates that file from its sole `VERSION` source during the same image build used for the matching Helm chart and release tag.

+# ADR 0001: Run Piper in an ES module worker
+
+## Decision
+
+Bundle the Piper worker as an ES module and start it with `new Worker(url, { type: 'module' })`.
+
+## Context
+
+Piper loads ONNX Runtime Web and its WebAssembly loader dynamically. The current IIFE/classic worker bundle reports `TypeError: "undefined" cannot be parsed as a URL` during WASM backend initialization, even though the pinned same-origin ONNX loader and binary are available. This is consistent with module-relative URL metadata being lost in the classic bundle.
+
+## Consequences
+
+The browser must support module workers. Current supported browser targets already require modern WebAssembly and worker support. CI asserts that the worker is built and started in module mode; production acceptance remains the real deployed browser flow.

+# ADR 0002: Run ONNX with one thread inside the Piper worker
+
+## Decision
+
+Configure ONNX Runtime Web to use one thread and stop backend initialization after 60 seconds. Piper already runs in a dedicated worker, so ONNX does not need to create another worker pool.
+
+## Context
+
+On iPad, the threaded ONNX WASM file downloaded fully, but the runtime did not report that initialization had completed. Nested worker startup and shared-memory setup are a likely compatibility boundary on mobile Safari. The available production assets currently include the threaded ONNX build.
+
+## Consequences
+
+This removes ONNX's additional worker pool and bounds initialization failures with a visible error. It may reduce inference throughput on desktop devices. CI and Kubernetes release verification must confirm that Piper still initializes and speaks on supported browsers; iPad acceptance remains a manual device check.

+# ADR 0003: Limit Piper WASM to one thread and reset failed workers
+
+## Decision
+
+The Piper worker reports one available processor to Piper and configures ONNX Runtime for one thread. If a synthesis request fails, the browser client terminates that worker; the next player retry creates a fresh worker and ONNX module.
+
+## Context
+
+Piper TTS Web 1.0.3 sets `env.wasm.numThreads` from `navigator.hardwareConcurrency` during `TtsSession.init()`, after the application had configured ONNX Runtime. On iPad this could undo the single-thread setting and request a larger WASM worker pool. The library also retains a singleton session if ONNX initialization fails, so retrying in the same worker can reuse a failed initialization.
+
+## Consequences
+
+The one-thread limit reduces parallel inference but lowers memory pressure on mobile Safari. Failed initialization no longer poisons future attempts in the same worker. This cannot guarantee that every device has enough memory for the 63 MB medium voice model; the CI release and Kubernetes checks validate packaging and deployment, while actual iPad memory behavior still requires device verification.

+# ADR 0004: Pause browser-local AI by default
+
+## Status
+
+Accepted
+
+## Decision
+
+Browser-local Gemma/Wllama assistance is disabled by the `FEATURE_FLAGS.localAI` flag in `index.html`. The adapter is loaded dynamically only when the flag is true. When it is false, the browser does not load the adapter, request model/runtime assets, initialize local inference, attach local hints to dialogue requests, or produce local offline replies. The normal text dialogue remains available through the Rust API.
+
+## Rationale
+
+Pause model execution while the rest of the game and narrator experience is stabilized. Keep the implementation available for a deliberate future reactivation without downloading model resources or sending local inference hints in the meantime.
+
+## Consequences
+
+- Re-enabling local AI requires an explicit code change and frontend release.
+- Tests and the static frontend check must enforce the default-off behavior and lazy loading.
+- Existing Gemma asset publication and documentation may remain in place; the browser does not request those assets while the flag is off.
