-Bitcoin price tracker UI — Clojure Kit web application. Serves the HTML/Tailwind UI. Connects to btcdata for live price data via WebSocket.
+Bitcoin price tracker UI — Python FastAPI web application. Serves the HTML/Tailwind UI and
+proxies live price data from btcdata over WebSocket.

 ## Build & Development Commands

- `make run` — Start dev server on port 4000
- `make repl` — Start nREPL
- `make test` — Run tests
+- `make run` — Start dev server on port 4000; creates `.venv` and installs `requirements.txt`
+  on first run (the `venv` target, keyed off `requirements.txt`)
+- `cp .env.example .env` — optional; `.env` is `-include`d, so a missing one is not fatal
+- `make run-local` — Same, but with `BTCDATA_URL=$BTCDATA_LOCAL_URL`
 - `make tailwind` — Watch Tailwind CSS for changes
- `make uberjar` — Build production JAR
- `docker compose up -d` — Start btcprice + btcdata containers
+- `make test` — Installs test-only dependencies from `requirements-dev.txt` and runs `pytest tests/`
+- `make venv` — Bootstrap the virtualenv without starting the server

 ## Docker

 Docker runs alongside local dev on different ports:

-| Service  | Local dev      | Docker         |
-|----------|----------------|----------------|
-| btcprice | localhost:4000 | localhost:4041 |
-| btcdata  | localhost:4100 | localhost:4101 |
+| Service  | Local dev      | Docker                               |
+|----------|----------------|--------------------------------------|
+| btcprice | localhost:4000 | localhost:4041 (container port 4040) |
+| btcdata  | localhost:4100 | localhost:4102                       |

-btcprice's docker-compose includes btcdata via `include: ../btcdata/docker-compose.yml`.
+`docker compose up -d` here starts **btcprice only**. Both projects attach to the external
+`btc-network` (`docker network create btc-network` once), and btcdata must be started from
+`../btcdata`. Inside the network btcprice reaches it at `http://btcdata:${DOCKER_BTCDATA_PORT:-4102}`.

-## REPL Commands
+The image does not set `BTCDATA_URL`; deployments must provide it. `BUILD_SHA` is embedded as
+`APP_VERSION` and exposed at `/api/version`. The port in `CMD` is hardcoded to 4040.

-```clojure
-(dev-prep!)   ;; Prepare dev system
-(go)          ;; Start system
-(reset)       ;; Reload code & restart
-(halt)        ;; Stop system
-```
+## CI/CD and production
+
+`.gitea/workflows/build.yml` tests pushes to `main` and `v*` tags on the `anvil` Gitea Actions
+runner, then publishes immutable linux/amd64 images to
+`harbor.pmagnus.cloud/btcprice/btcprice`. It embeds the short Git SHA as `APP_VERSION`.
+
+Flux image automation updates the manifests in the separate `magnus/deploy` repository and Flux
+reconciles k3s. CI has no Kubernetes credentials. Production runs two replicas—one on hostinger and
+one on citadel—and is served at https://btcprice.k8s.pmagnus.cloud through ingress-nginx and
+hostinger Traefik TLS. Deployment changes belong in `../deploy/apps/btcprice`; do not deploy with
+Compose or manual `kubectl apply`.
+
+## Legacy deployment
+
+`./deploy-citadel.sh` — build locally for the remote's arch, `docker save | ssh docker load`,
+`docker compose up -d --no-build` in `/home/pmp/apps/btcprice` on citadel (192.168.50.195).
+Mirrors `../elprice/deploy-citadel.sh`; no registry.
+
+- `docker-compose.citadel.yml` → remote `docker-compose.yml`; `.env.citadel` → remote `.env`.
+- btcdata also runs on citadel, so both attach to the external `btc-network` there and
+  `BTCDATA_URL` is `http://btcdata:4102` (service name, not a LAN address). The deploy script
+  creates the network on the remote if it is missing.
+- Temporary migration fallback at http://192.168.50.195:4041; it is not the production endpoint.

 ## Architecture

- **Framework:** Kit (Integrant-based)
- **Server:** Undertow
- **Routing:** Reitit
- **Templates:** Hiccup + HTMX (WebSocket extension)
+- **Framework:** FastAPI
+- **Server:** Uvicorn
+- **Templates:** Inline HTML strings + HTMX (WebSocket extension)
 - **Styling:** Tailwind CSS v4
- **Data backend:** btcdata (separate service at BTCDATA_URL, default http://localhost:4100)
+- **Data backend:** btcdata (separate service at `BTCDATA_URL`, default `http://localhost:4100`)
 - **No database** — all data comes from btcdata
+- **Probes:** `/api/health` is process-only liveness; `/api/ready` checks btcdata with a 3-second
+  timeout; `/api/version` exposes the build identifier
+
+### btcdata connection
+
+The browser connects only to btcprice: `ws-connect="/ws/price"` and `ws-connect="/ws/strike"`.
+Each endpoint runs `_ws_proxy`, which opens an upstream WebSocket to btcdata's `/api/price/ws`
+and `/api/strike/ws`, converts each JSON message to an HTML fragment (`price_json_to_html`,
+`strike_json_to_html`) and forwards it. `BTCDATA_URL` is the single point of contact;
+`_btcdata_ws_url` rewrites its scheme to `ws`/`wss`.

+btcprice acts as a WebSocket proxy between the browser and btcdata:
+1. Browser connects via HTMX WebSocket to `/ws/price` or `/ws/strike`
+2. btcprice proxies to btcdata's `/api/price/ws` or `/api/strike/ws`
+3. JSON from btcdata is transformed into HTML fragments (in `price_json_to_html` / `strike_json_to_html`)
+4. HTMX swaps the HTML into the DOM by matching element IDs (`price-display`, `strike-display`)
+
+### Key Conventions
+
+- Numbers use Danish locale formatting (dots for thousands, commas for decimals) via `da_fmt()`
+- Price changes are color-coded: green (up), red (down), gray (unchanged)
+- All HTML is built as string concatenation in Python — no template engine

+# Pull-request deployment workflow
+
+## Intended result
+
+Production deployment should happen only after a change has followed this path:
+
+```text
+feature branch
+  -> local test and local application run
+  -> pull request with automated checks
+  -> owner reviews the result and approves by merging
+  -> merge to main
+  -> Gitea Actions builds and publishes an immutable image
+  -> Flux updates magnus/deploy
+  -> Flux reconciles Kubernetes
+  -> production verification
+```
+
+For this single-user repository, clicking **Merge** after reviewing the diff and successful checks
+is the approval. The merge creates the `push` event which starts the existing production build.
+
+## Findings (2026-09-17)
+
+- The default branch is `main`.
+- Gitea reports no branch-protection rule for this repository. A contributor can therefore push
+  directly to `main`, bypassing a pull request and approval.
+- `.gitea/workflows/pr.yml` now runs tests for pull requests targeting `main`; it has no publish
+  step and receives no Harbor credentials.
+- `.gitea/workflows/build.yml` remains restricted to pushes to `main` and `v*` tags. A merged PR
+  therefore starts the existing image publication and automatic Kubernetes deployment path.
+- Recent `main` workflow runs show that the existing post-merge build and publish workflow works.
+- The workflow runs `pytest`, builds a linux/amd64 image, and publishes immutable
+  `main-<UTC timestamp>` and SHA-qualified tags to
+  `harbor.pmagnus.cloud/btcprice/btcprice`.
+- Flux watches the plain `main-<UTC timestamp>` tags. Its image automation writes the selected tag
+  into `magnus/deploy`, after which Flux reconciles the Kubernetes cluster.
+- Kubernetes runs two replicas with rolling updates, health/readiness probes, and one pod per node.
+- Gitea currently has only one user (`magnus`). Mandatory reviewer approval is therefore not
+  appropriate: Gitea does not provide meaningful independent self-approval. The owner's explicit
+  merge action is the approval, while branch protection and CI remain the enforceable gates.
+
+## Required one-time configuration
+
+### 1. Pull-request validation workflow (implemented)
+
+`.gitea/workflows/pr.yml` validates every pull request targeting `main`. It checks out the proposed
+commit and runs the tests without publishing an image or receiving Harbor credentials. The
+production Docker image is built locally before the PR and again by `build.yml` after merge.
+
+```bash
+python -m pip install -r requirements-dev.txt
+python -m pytest tests/
+```
+
+The contributor performs the Docker build locally before opening the PR. Keeping it out of the PR
+job avoids giving proposed code credentials for the private Harbor base images. After merge, the
+trusted `build.yml` workflow builds the production image with Harbor credentials.
+
+Keep image publication restricted to the existing `push` event for `main` and `v*` tags. PR code,
+especially code from an untrusted fork, must not receive the Harbor credentials.
+
+The workflows are intentionally separated:
+
+- `pr.yml`: `pull_request` trigger; tests only; no secrets and no push.
+- `build.yml`: existing `push` trigger; tests, image build, Harbor scan gate, and image push.
+
+### 2. Protect `main` in Gitea (configuration still required)
+
+In `magnus/btcprice`, open **Settings -> Branches -> Branch protection rules** and protect `main`.
+Configure the rule to:
+
+- disable direct pushes (and force pushes);
+- require pull requests before merge;
+- set required approvals to zero while the repository has only one user;
+- block merge when a review requests changes;
+- require the PR validation status check;
+- require the branch to be up to date before merge;
+- restrict bypass/whitelist permissions to emergency administrators only.
+
+Create the PR workflow and let it run once before selecting its status-check context in the branch
+rule; this avoids guessing Gitea's generated context name. With required approvals set to zero, the
+owner reviews the diff and approves it by clicking **Merge** after the required check passes. If a
+second trusted user is added later, change the rule to require one approval and dismiss stale
+approvals when new commits are pushed.
+
+## Per-change procedure
+
+### 1. Create a feature branch
+
+Start from the latest production branch:
+
+```bash
+git switch main
+git pull --ff-only
+git switch -c feature/<short-description>
+```
+
+Make and commit the change on this branch. Do not commit `.env`; it contains local configuration.
+
+### 2. Test and run the branch locally before opening the PR
+
+Run the automated tests:
+
+```bash
+make test
+```
+
+For a functional check, start `btcdata` in one terminal:
+
+```bash
+cd ../btcdata
+make run
+```
+
+Then start this branch of `btcprice` in another terminal:
+
+```bash
+cd ../btcprice
+make run
+```
+
+Open `http://localhost:4000` and confirm that both live price streams update. Also check the
+application endpoints:
+
+```bash
+curl --fail http://localhost:4000/api/health
+curl --fail http://localhost:4000/api/ready
+curl --fail http://localhost:4000/api/version
+```
+
+`/api/health` checks the btcprice process; `/api/ready` also verifies that btcdata is reachable.
+The local version normally reports `development`.
+
+Finally, exercise the production build path:
+
+```bash
+docker build \
+  --build-arg BUILD_SHA="$(git rev-parse --short HEAD)" \
+  -t btcprice:pr-check .
+```
+
+If Docker validation needs the complete local stack, create `btc-network` once, start btcdata's
+Compose project, and run `docker compose up --build` in this repository. This application then
+listens at `http://localhost:4041`.
+
+Record the tests and manual behavior checked in the PR description.
+
+### 3. Push and open the pull request
+
+```bash
+git push -u origin feature/<short-description>
+tea pulls create \
+  --repo magnus/btcprice \
+  --base main \
+  --head feature/<short-description> \
+  --title "<concise change title>"
+```
+
+The PR should explain the change, risk, local verification, and rollback considerations. Wait for
+the PR validation job to pass, then review and merge it. Any new commit triggers validation again.
+
+### 4. Approve and merge
+
+As repository owner, check the diff, confirm the automated result, and verify the stated manual
+test. Clicking **Merge** is the approval step in this single-user setup. Prefer **squash merge** for
+small, single-purpose PRs or use another consistent merge policy.
+
+Do not press merge if the check is failing or the PR branch is behind `main`. Do not deploy with
+`kubectl apply` or `deploy-citadel.sh`; those bypass the GitOps audit trail.
+
+### 5. Observe the deployment
+
+After merge, observe this sequence:
+
+1. Gitea Actions tests the merge commit.
+2. It publishes `main-<UTC timestamp>` and `main-<UTC timestamp>-<short SHA>`.
+3. Harbor scans the image and permits the companion tag after policy approval.
+4. Flux image reflection selects the newest plain `main-<UTC timestamp>` tag.
+5. Flux commits the updated image reference to `magnus/deploy`.
+6. Flux applies that Git state and Kubernetes performs a rolling update.
+
+The CI job intentionally has no Kubernetes credentials. A successful image build is not by itself
+proof of a successful rollout, so verify production separately:
+
+```bash
+curl --fail https://btcprice.k8s.pmagnus.cloud/api/health
+curl --fail https://btcprice.k8s.pmagnus.cloud/api/ready
+curl --fail https://btcprice.k8s.pmagnus.cloud/api/version
+```
+
+The production version should equal the short SHA of the merged btcprice commit. Also confirm in
+the deployment repository or cluster that both replicas became Ready. If rollout access is
+available, useful checks are:
+
+```bash
+flux get kustomizations
+kubectl -n btcprice rollout status deployment/btcprice
+kubectl -n btcprice get pods -o wide
+```
+
+## Failure and rollback behavior
+
+- If PR validation fails, fix the feature branch; nothing has been published or deployed.
+- If the post-merge build fails, Kubernetes keeps running the previous image. Fix forward through a
+  new PR; do not manually push a replacement under an existing immutable tag.
+- If Harbor rejects the image, Flux cannot select it and production stays on the previous image.
+- If a new image deploys but is bad, revert the Flux image commit in `magnus/deploy`, or commit the
+  last known-good immutable tag there. Flux then restores that version. Follow up with a revert or
+  fix PR in this repository so future automation does not reintroduce the bad build.
+
+## Security boundary
+
+The separation is intentional:
+
+- PR jobs validate untrusted proposed code without deployment or registry credentials.
+- The protected `main` branch is the release authorization boundary.
+- Gitea Actions may write images to Harbor only after merge.
+- Flux alone has authority to update the GitOps repository and reconcile Kubernetes.
+- Kubernetes changes remain reviewable and recoverable through Git history.

-# btcprice
-
-Bitcoin price tracker UI. Serves an HTML page with live price updates streamed from [btcdata](../btcdata) via WebSocket using HTMX.
-
-## Quick Start
-
-```bash
-# Start btcdata first (provides price data)
-cd ../btcdata && make run
-
-# Local dev
-make run       # starts on port 4000
-make tailwind  # watch Tailwind CSS (separate terminal)
-
-# Docker (starts both btcprice + btcdata)
-docker compose up -d   # btcprice on 4041, btcdata on 4101
-```
-
-## Environment Variables
-
-| Variable | Default | Description |
-|---|---|---|
-| `PORT` | `4000` | HTTP server port |
-| `BTCDATA_URL` | `http://192.168.50.42:4100` | btcdata service URL (browser connects via WebSocket) |
-
-## How It Works
-
-The server renders an HTML page with HTMX and the WebSocket extension (`hx-ext="ws"`). HTMX connects directly to btcdata's WebSocket endpoint (`BTCDATA_URL/api/price/ws`), which sends HTML fragments. HTMX swaps the received `<div id="price-display">` into the DOM automatically. Price changes are color-coded (green up, red down). Reconnection is handled by HTMX with exponential backoff.

+# btcprice
+
+Bitcoin price tracker UI. Serves an HTML page with live price updates streamed from
+[btcdata](../btcdata), which this server proxies over WebSocket and renders as HTML fragments
+for HTMX.
+
+## Quick Start
+
+```bash
+# Start btcdata first (provides price data)
+cd ../btcdata && make run
+
+# Local dev — creates .venv and installs requirements on first run
+make run       # starts on port 4000
+make tailwind  # watch Tailwind CSS (separate terminal)
+```
+
+Optionally `cp .env.example .env` to override `BTCDATA_URL`; without it the code default
+(`http://localhost:4100`) applies. `make run-local` requires a `.env` defining
+`BTCDATA_LOCAL_URL`.
+
+Run the test suite with `make test`. Test-only packages are kept in `requirements-dev.txt` and are
+not installed in the production image.
+
+## Docker
+
+`docker compose up -d` starts **btcprice only** — it does not bring up btcdata. Both compose
+files attach to the external `btc-network`, so create it once and start btcdata separately:
+
+```bash
+docker network create btc-network      # once
+cd ../btcdata && docker compose up -d
+cd ../btcprice && docker compose up -d
+```
+
+| Service  | Local dev      | Docker                                |
+|----------|----------------|---------------------------------------|
+| btcprice | localhost:4000 | localhost:4041 (container port 4040)  |
+| btcdata  | localhost:4100 | localhost:4102                        |
+
+Inside `btc-network`, btcprice reaches btcdata as `http://btcdata:4102`.
+
+## CI images
+
+Pushes to the `main` branch and tags matching `v*` run
+`.gitea/workflows/build.yml`. The workflow tests the application and publishes linux/amd64 images
+to `harbor.pmagnus.cloud/btcprice/btcprice`. Branch builds receive an immutable
+`main-<UTC timestamp>` tag (for Flux selection) and a SHA-qualified companion tag; release tags
+receive the version without `v` and a SHA-qualified companion tag. The image embeds the short Git
+SHA, available from `/api/version`.
+
+The workflow requires the repository secrets `HARBOR_ROBOT_USER` and `HARBOR_ROBOT_TOKEN`. It only
+pushes images and intentionally has no Kubernetes credentials.
+
+## Production deployment
+
+Production is GitOps-managed at **https://btcprice.k8s.pmagnus.cloud**:
+
+```text
+git push → Gitea Actions on anvil → Harbor → Flux → k3s → ingress-nginx → Traefik TLS
+```
+
+Flux image automation commits the newest approved `main-<UTC timestamp>` image to the separate
+`magnus/deploy` repository. The manifests are in `../deploy/apps/btcprice`, and two replicas run with
+one pod on each k3s node. CI never receives cluster credentials. Do not deploy production with
+Docker Compose or manual `kubectl apply`; rollback by reverting the immutable image change in the
+GitOps repository.
+
+btcdata remains an external dependency running on citadel. Kubernetes represents it with a
+selectorless Service and EndpointSlice, so pods use `http://btcdata:4102` without embedding its IP in
+the Deployment.
+
+## Legacy deployment (citadel)
+
+```bash
+./deploy-citadel.sh
+```
+
+Same method as `../elprice/deploy-citadel.sh`: builds the image locally for the target's
+architecture (citadel is x86_64 → `linux/amd64`), copies `docker-compose.citadel.yml` and
+`.env.citadel` to `/home/pmp/apps/btcprice` on the host as `docker-compose.yml` / `.env`,
+pipes the image over SSH with `docker save | docker load`, and runs
+`docker compose up -d --no-build`. No registry involved.
+
+The temporary migration fallback listens on **http://192.168.50.195:4041** and proxies to the
+btcdata running on citadel as well. It is retained only for the validation/rollback window; the
+Kubernetes hostname is the production endpoint. Both attach to the external `btc-network` there, so `BTCDATA_URL` is
+`http://btcdata:4102` (set in `.env.citadel`) — the service name inside the network, not a LAN
+address. The deploy script creates `btc-network` on the host if it does not exist yet.
+
+Overridable: `BTCPRICE_DEPLOY_HOST`, `BTCPRICE_DEPLOY_DIR`, `BTCPRICE_IMAGE_NAME`,
+`BTCPRICE_PLATFORM`, `BTCPRICE_NETWORK`.
+
+## Environment Variables
+
+| Variable | Default | Description |
+|---|---|---|
+| `BTCDATA_URL` | `http://localhost:4100` | btcdata service URL the server proxies to |
+| `APP_VERSION` | `development` | Build identifier returned by `/api/version` |
+| `BTCDATA_LOCAL_URL` | — | Used by `make run-local` instead of `BTCDATA_URL` |
+| `DOCKER_BTCDATA_PORT` | `4102` | btcdata's port inside `btc-network` (local compose only) |
+| `BTCPRICE_PORT` | `4041` | Host port in the citadel deployment (`.env.citadel`) |
+
+The HTTP port is not configurable via environment: `make run` hardcodes 4000 and the Docker
+image's `CMD` hardcodes 4040.
+
+## Health endpoints
+
+- `/api/health` is a process-only liveness check and remains healthy during a btcdata outage.
+- `/api/ready` checks `${BTCDATA_URL}/api/health` with a three-second timeout and returns 503 when
+  btcdata is unavailable.
+- `/api/version` returns the build SHA embedded by CI.
+
+## How It Works
+
+The browser loads a page with HTMX and the WebSocket extension, which connects back to
+**btcprice** at `/ws/price` and `/ws/strike` — the browser never contacts btcdata directly.
+
+Each of those endpoints opens an upstream WebSocket to btcdata (`/api/price/ws` and
+`/api/strike/ws`), converts each JSON message to an HTML fragment (`price_json_to_html`,
+`strike_json_to_html`), and forwards it to the browser. HTMX swaps the received
+`<div id="price-display">` / `<div id="strike-display">` into the DOM. Price changes are
+color-coded (green up, red down). Reconnection is handled by HTMX.

+# btcprice GitOps migration plan
+
+**Status (2026-09-15):** Phases 1–6 implemented and verified. The GitOps deployment is live with
+one Ready replica on each k3s node, trusted TLS, working HTTP/WebSockets, and a successful unattended
+source-to-production update. Compose remains online for the required 24-hour validation/rollback
+window; Phase 7 is intentionally pending.
+
+**Target path**
+
+```text
+git push (magnus/btcprice)
+  -> Gitea Actions on anvil
+  -> Harbor image + Trivy scan
+  -> Flux image policy commits magnus/deploy
+  -> Flux reconciles k3s
+  -> ingress-nginx
+  -> hostinger Traefik TLS
+  -> https://btcprice.k8s.pmagnus.cloud
+```
+
+Production deployment must not use `docker compose`, `kubectl apply` from CI, or a CI-held
+kubeconfig. The existing Compose instance on citadel is retained only during validation and as a
+short rollback path.
+
+## Access and secret handling
+
+Use `/Users/pmagnus/pi/system/.env` for Gitea, Harbor, host and Cloudflare credentials. The file is
+mode `0600` and must remain outside Git.
+
+```bash
+set -a
+. ../system/.env
+set +a
+```
+
+Rules:
+
+- never echo tokens/passwords or put them in command arguments;
+- pass secrets via API headers, stdin, or temporary `0600` files;
+- use the Harbor CI robot for image pushes, the existing cluster pull robot for pulls, and Harbor
+  admin only for project policy changes;
+- use the Gitea token for API administration, not from application or workflow code;
+- do not copy `../system/.env` into this repository, an image, a pod, or `magnus/deploy`.
+
+## Audited starting point (2026-09-15)
+
+Already working:
+
+- `magnus/btcprice` uses `main`; `.gitea/workflows/build.yml` tests and publishes immutable amd64
+  images from `anvil`.
+- The latest Gitea run for commit `dd67eb7` succeeded.
+- Harbor project `btcprice` is private, scans on push, blocks High-or-worse vulnerable images, has a
+  retention policy and weekly garbage collection. The latest image is scanned successfully:
+  `main-20260915160353` / `main-20260915160353-dd67eb7`.
+- The repository has `HARBOR_ROBOT_USER` and `HARBOR_ROBOT_TOKEN` Actions secrets.
+- The image exposes `/api/health`, dependency-aware `/api/ready`, and `/api/version`.
+- Flux and all image automation controllers are healthy. The `hello` canary proves unattended image
+  update, reconciliation, two-node scheduling, ingress, and TLS.
+- k3s has two Ready amd64 nodes: `srv1893094` and `citadel`.
+- Both nodes already have Harbor pull credentials.
+- ingress-nginx is managed by Flux and is reached through hostinger Traefik on NodePort 30080.
+- btcdata still runs under Compose on citadel and answers on `100.75.8.131:4102`.
+- The old btcprice Compose container remains available on citadel port 4041.
+
+Current gaps:
+
+- `magnus/deploy` has no btcprice resources or image policy.
+- `btcprice.k8s.pmagnus.cloud` currently reaches Traefik but receives its default certificate and an
+  nginx 404; the TLS domain and Kubernetes Ingress do not exist yet.
+- Local `../deploy` can lag Flux's automated commits. Always run `git pull --ff-only` before editing.
+- Harbor's release retention rule currently keeps `v*`, while the workflow strips the leading `v`
+  (`v1.2.3` becomes `1.2.3`). Correct that mismatch before relying on release retention.
+- The Gitea btcprice repository is currently public. Confirm that this is intentional; it does not
+  expose the Actions secrets, but it does expose source and workflow definitions.
+
+## Phase 1 — close pre-deployment policy gaps
+
+1. In Harbor, change the release retention rule to match the tags the workflow actually emits
+   (plain semantic versions and their SHA-qualified companion tags), or change the workflow to retain
+   the `v` prefix. Prefer changing retention so existing image naming remains stable.
+2. Confirm `buildcache` remains explicitly retained and excluded from application deployment policy.
+3. Confirm the exact latest digest is pullable on both k3s nodes after its Trivy scan passes.
+4. Run `make test` locally and confirm the published image reports `dd67eb7` from `/api/version`.
+5. Decide whether `magnus/btcprice` should remain public.
+
+**Gate:** no Kubernetes manifests are merged until tests pass, the latest immutable image is approved
+by Harbor, and both nodes can pull it.
+
+## Phase 2 — represent the external btcdata dependency in Kubernetes
+
+Create the following in `../deploy/apps/btcprice/`:
+
+- `namespace.yaml`
+- `btcdata-service.yaml`
+- `btcdata-endpointslice.yaml`
+
+Use namespace `btcprice`. Define a selectorless ClusterIP Service named `btcdata` on port `4102` and
+an EndpointSlice with:
+
+- label `kubernetes.io/service-name: btcdata`;
+- address type `IPv4`;
+- endpoint `100.75.8.131`;
+- TCP port `4102`.
+
+The application then uses only:
+
+```text
+BTCDATA_URL=http://btcdata:4102
+```
+
+Do not embed citadel's IP in the Deployment. This abstraction lets btcdata move into Kubernetes later
+without changing btcprice.
+
+Test from disposable pods pinned once to `srv1893094` and once to `citadel`:
+
+- `http://btcdata:4102/api/health` returns 200;
+- `/api/kraken-minute` and `/api/kraken-hour` return JSON;
+- WebSocket connections to `/api/price/ws` and `/api/strike/ws` receive data.
+
+**Gate:** all HTTP and WebSocket checks pass from both nodes.
+
+## Phase 3 — add the btcprice workload to `magnus/deploy`
+
+First synchronize the GitOps checkout:
+
+```bash
+git -C ../deploy pull --ff-only
+git -C ../deploy switch main
+```
+
+Add this structure:
+
+```text
+apps/btcprice/
+  namespace.yaml
+  btcdata-service.yaml
+  btcdata-endpointslice.yaml
+  deployment.yaml
+  service.yaml
+  ingress.yaml
+  pdb.yaml
+  kustomization.yaml
+infrastructure/image-automation/
+  btcprice-image.yaml
+```
+
+Also update:
+
+- `apps/kustomization.yaml` to include `btcprice`;
+- `infrastructure/image-automation/kustomization.yaml` to include `btcprice-image.yaml`.
+
+### Deployment specification
+
+Use:
+
+- image `harbor.pmagnus.cloud/btcprice/btcprice:<known-good-main-tag>`;
+- Flux marker `# {"$imagepolicy": "flux-system:btcprice"}` on the image;
+- two replicas and container port `4040`;
+- `BTCDATA_URL=http://btcdata:4102`;
+- `terminationGracePeriodSeconds: 30`;
+- rolling update with `maxUnavailable: 1` and `maxSurge: 0`;
+- initial resources of approximately `50m` CPU / `64Mi` memory requested and `250m` CPU / `256Mi`
+  memory limited, then tune from observed metrics.
+
+Guarantee one replica on each node with:
+
+- required node affinity allowing only hostnames `srv1893094` and `citadel`;
+- required pod anti-affinity on `kubernetes.io/hostname`, matching
+  `app.kubernetes.io/name: btcprice`.
+
+Hard anti-affinity plus two replicas and two eligible nodes gives one pod per node. `maxSurge: 0`
+prevents rollout deadlock because a third pod cannot satisfy that anti-affinity.
+
+Use probes:
+
+- startup: `GET /api/health`;
+- liveness: `GET /api/health`;
+- readiness: `GET /api/ready`, with Kubernetes timeout longer than the application's three-second
+  upstream timeout.
+
+Never use dependency-aware readiness as liveness; a btcdata outage must not restart healthy
+btcprice processes.
+
+### Service, disruption budget, and ingress
+
+- ClusterIP Service: port `80` to named container port `4040`.
+- PDB: `minAvailable: 1`.
+- Ingress class: `nginx`.
+- Host: `btcprice.k8s.pmagnus.cloud`.
+- Path: `/`, `Prefix`, backend `btcprice:80`.
+- No Kubernetes TLS secret: TLS terminates at hostinger Traefik.
+- Add ingress-nginx proxy read/send timeouts suitable for long-lived WebSockets (for example 3600
+  seconds). WebSocket upgrade support itself is automatic.
+
+## Phase 4 — add Flux image automation
+
+Follow the existing `hello` convention in `../deploy/infrastructure/image-automation/`:
+
+- `ImageRepository` named `btcprice` in `flux-system`;
+- image `harbor.pmagnus.cloud/btcprice/btcprice`;
+- existing pull-only secret `harbor-pull`;
+- one-minute scan interval;
+- `ImagePolicy` matching only plain branch tags:
+
+```yaml
+filterTags:
+  pattern: '^main-(?P<ts>[0-9]{14})$'
+  extract: '$ts'
+policy:
+  numerical:
+    order: asc
+```
+
+This intentionally excludes SHA-qualified tags, releases, and `buildcache`. The existing
+`ImageUpdateAutomation/apps` object will update files under `./apps`, commit to `magnus/deploy`, and
+cause Flux to reconcile. CI receives no GitOps write key or kubeconfig.
+
+Validate manifests before pushing:
+
+```bash
+kubectl kustomize ../deploy/apps/btcprice >/dev/null
+kubectl kustomize ../deploy/apps >/dev/null
+kubectl kustomize ../deploy/infrastructure/image-automation >/dev/null
+```
+
+Commit and push only to `magnus/deploy`; do not manually apply the resources. Watch Flux and verify
+that all Kustomizations remain Ready.
+
+## Phase 5 — enable ingress TLS
+
+On hostinger, edit the file-provider configuration mounted at:
+
+```text
+/home/pmp/apps/netbird/traefik-dynamic.yaml
+```
+
+Add this entry under `http.routers.k8s-ingress.tls.domains`:
+
+```yaml
+- main: "btcprice.k8s.pmagnus.cloud"
+```
+
+Use `SUDO_HOSTINGER` from `../system/.env` only if privilege escalation is required. Back up the file
+first and preserve permissions. Do **not** restart Traefik: its file provider hot-reloads, and a
+restart can interrupt ACME and NetBird traffic.
+
+Wait for issuance and verify externally:
+
+```bash
+curl --fail https://btcprice.k8s.pmagnus.cloud/api/health
+curl --fail https://btcprice.k8s.pmagnus.cloud/api/ready
+```
+
+The certificate must be publicly trusted and named for `btcprice.k8s.pmagnus.cloud`; do not accept the
+current self-signed `TRAEFIK DEFAULT CERT`.
+
+## Phase 6 — acceptance and unattended deployment test
+
+### Initial deployment
+
+Confirm:
+
+- both Flux application and infrastructure Kustomizations are Ready;
+- `ImageRepository`, `ImagePolicy`, and `ImageUpdateAutomation` are Ready;
+- exactly two btcprice pods are Ready, one on each node;
+- Service endpoints contain both pods;
+- `/`, CSS, favicon, chart APIs, health, readiness, and version endpoints work externally;
+- `/ws/price` and `/ws/strike` remain connected and update through ingress;
+- the running `/api/version` equals the expected image's embedded short SHA.
+
+### Full pipeline test
+
+Push a harmless visible change to `magnus/btcprice` and observe, without manual deployment actions:
+
+1. Gitea queues the workflow on `anvil`.
+2. Tests pass.
+3. Harbor receives the timestamp and SHA-qualified tags.
+4. Trivy approves the artifact.
+5. Flux image reflection selects the new plain timestamp tag.
+6. Flux commits the image change to `magnus/deploy`.
+7. kustomize-controller rolls out the Deployment.
+8. `/api/version` changes to the pushed source SHA.
+
+### Failure tests
+
+- Delete each pod in turn; one endpoint remains available and the missing node gets a replacement.
+- During a rollout, verify browser WebSockets reconnect after old pods terminate.
+- Temporarily make btcdata unreachable in a controlled window; readiness becomes false, liveness
+  remains true, and no restart loop occurs.
+- Verify a Harbor-rejected image cannot become a healthy rollout.
+- Revert a GitOps image commit and confirm Flux restores the prior immutable image.
+
+**Acceptance criterion:** a normal source push changes production with no SSH, Compose, or manual
+`kubectl` deployment, while Git records the deployed image.
+
+## Phase 7 — cut over from Compose
+
+Keep `http://192.168.50.195:4041` running in parallel for at least 24 hours after all acceptance tests
+pass. It must not own the new Kubernetes hostname.
+
+Then on citadel:
+
+1. Record the legacy image ID and effective environment for rollback without recording secrets.
+2. Stop only `/home/pmp/apps/btcprice`; do not stop btcdata, Frankfurter, PostgreSQL, or remove
+   `btc-network`.
+3. Verify no clients still use port 4041.
+4. Keep `deploy-citadel.sh`, `docker-compose.citadel.yml`, and `.env.citadel` for one defined rollback
+   window, clearly marked legacy/manual-only.
+5. After that window, remove the legacy deployment files and update `README.md`, `CLAUDE.md`, and
+   `../system/infrastructure.md` so GitOps is the only production path.
+
+## Rollback
+
+Application rollback:
+
+1. Suspend the btcprice `ImagePolicy` or image automation if it would immediately reselect the bad
+   tag.
+2. Revert the automated image commit in `magnus/deploy`, or commit the previous known-good immutable
+   tag.
+3. Let Flux reconcile and verify readiness/version.
+4. Re-enable automation only after the bad tag is no longer selectable.
+
+Migration rollback while Compose is retained:
+
+1. Remove or suspend the btcprice Ingress through Git and let Flux reconcile.
+2. Restart only the recorded btcprice Compose service on citadel.
+3. Restore clients temporarily to port 4041.
+4. Diagnose without deleting Harbor artifacts or rewriting Git history.
+
+## Known limitation and follow-up
+
+Two frontend replicas do not make the full system highly available: btcdata and its database remain
+single-node dependencies on citadel. If citadel fails, the hostinger btcprice pod may serve static
+content but readiness and live data fail. Migrate btcdata and decide PostgreSQL storage/availability
+in a separate change; then replace the selectorless Service and EndpointSlice with a normal
+Kubernetes Service.

magnusandClaude Opus 5	864674bd09	Point citadel btcprice at the local btcdata over btc-network omarchy is gone, but the citadel deployment still set BTCDATA_URL=http://192.168.50.42:4102 and ran standalone on its own compose network. Every request that proxies to btcdata failed with httpx.ConnectError: All connection attempts failed. btcdata now runs on citadel too, so attach btcprice to the external btc-network there and reach it by service name at http://btcdata:4102. deploy-citadel.sh creates the network on the remote if missing, as btcdata's own deploy script already does.

magnusandClaude Opus 5	2af8b6f62d	Add citadel deployment Port of ../elprice/deploy-citadel.sh: build the image locally for the remote's architecture, ship it over SSH with docker save \| docker load, and run docker compose up -d --no-build in /home/pmp/apps/btcprice. The deployment compose is standalone rather than joining btc-network, because citadel runs no btcdata — BTCDATA_URL points at the instance already running on omarchy (http://192.168.50.42:4102).
