-- **The image is built from the checkout instead of pulled**: `docker-compose.yml` no longer references the `autumn27/artex` namespace, whose repository is gone and whose name its holder could republish at any time. `install.sh` and `update.sh` build the image locally.
-- **`update.sh` refuses to rebuild stale code**: when `git pull --ff-only` fails on a diverged clone (including every clone made before the 2026-10-23 history rewrite), it now stops with recovery commands instead of warning, rebuilding the old tree and printing "Build complete".
-
-### Fixed

-- **Ollama base URL on the environment path**: `ARTEX_LLM_BASE_URL=http://host:11434` is normalized to the `/v1` root the same way the saved-profile path already was, so a LAN Ollama server configured through the environment no longer answers 404 on chat.
+Ollama support, a setup token for the first-run claim, secret scrubbing for child processes, a Docker image that builds from a fresh clone, Go 1.26.10 and Node 22, and race and shellcheck runs in CI. Entries marked "direct commit" landed on `main` without a pull request.
 
 ### Added
 
 - **Ollama support**: an `ollama` LLM profile format for a local or LAN Ollama server. Keyless by design: no API key is needed, `OPENAI_API_KEY` is never inherited, the base URL defaults to `http://127.0.0.1:11434/v1` and is normalized to the `/v1` root, and the profile works in the failover pool, task LLM chains, model listing and connection tests. Contributed by @glauberportella (#128).
+- **Setup token for first-run setup**: while no admin password is set, the server generates a random 128-bit one-time token at startup and prints it to its log (`docker compose logs artex | grep "Setup token"`). The `/setup` page has a field for it, `POST /api/auth/init` requires it (`setup_token`, compared in constant time, 403 when missing or wrong), and it is cleared once the password is stored (#137).
+- **`ARTEX_BIND_ADDR`**: the address `docker-compose.yml` publishes the web UI on, default `127.0.0.1` (#137).
+
+### Security
+
+- **First-run claim**: before, anyone who reached port 8787 on a fresh install before the operator could set the admin password. Init now needs the setup token above, and Docker installs publish 8787 on `127.0.0.1` by default; set `ARTEX_BIND_ADDR=0.0.0.0` in `.env`, or use a reverse proxy or SSH tunnel, for remote access (#137).
+- **Startup secrets removed from the environment**: `ARTEX_PG_DSN`, `ANTHROPIC_API_KEY` and `OPENAI_API_KEY` are unset inside `server.New` after they are read and before the MCP discovery goroutine and the task resume loop start, so agent shells, MCP stdio servers and custom tools spawned afterwards no longer inherit them (#136). The binary passes the option that enables this, but `New` did not apply its options, so the scrub from #136 never ran until #146 fixed it (#146). See Known issues for what this does not cover.
+- **Saved API keys go only to their own endpoint**: `POST /api/llm/test` and `POST /api/llm/models` used a saved key (the profile's, or the global one) for any `base_url` in the request body, so a crafted request could send it to another host. A saved key is now sent only when the request's provider and normalized base URL match the ones it was saved for; otherwise the request must carry `api_key` (#142).
+- **`ARTEX_LLM_PROVIDER` is matched case-insensitively**: `Ollama` or a value with surrounding spaces fell through to the Anthropic default and sent `ANTHROPIC_API_KEY` to the configured base URL (#140).
+
+### Fixed
+
+- **Ollama base URL on the environment path**: `ARTEX_LLM_BASE_URL=http://host:11434` is normalized to the `/v1` root the same way the saved-profile path already was, so a LAN Ollama server configured through the environment no longer answers 404 on chat (direct commit 1c35c9c).
+- **Malformed `config.json` is an error**: `config.Load` used to ignore a parse error and treat the file as missing, which surfaced as a misleading "no database config found" or a silently ignored `skill_dir`. A read or parse error is now returned with the file path and startup exits (#141).
+- **`install.sh` escapes what it writes**: the local install writes `config.json` string values through a JSON escaper and requires a numeric port; the Docker install escapes `\`, `|` and `&` in the Postgres password and API key before the `.env` substitution (#141).
+- **`scripts/backup.sh --keep 0` is rejected**: it used to delete every dump, including the one just written, and still report success. Values with a leading zero are rejected too (#139).
+- **`backups/` is ignored again**: a missing newline had merged it into the previous `.gitignore` line, so database dumps showed up as untracked files (#138).
+
+### Build and CI
+
+- **The image is built from the checkout instead of pulled**: `docker-compose.yml` no longer references the `autumn27/artex` namespace, whose repository is gone and whose name its holder could republish at any time. `install.sh` and `update.sh` build the image locally (direct commit 1ed154e).
+- **A fresh clone builds the image**: the Dockerfile copied a prebuilt `dist/<arch>/artex` that a clean checkout does not have. It is now a multi-stage build: a Node 22 stage runs the frontend static export, a Go 1.26 stage runs `build.sh` with the release binaries job's flags (CGO-free cross-compile, `-trimpath`, version stamp), and the runtime stage copies the result (#147).
+- **`update.sh` refuses to rebuild stale code**: when `git pull --ff-only` fails on a diverged clone (including every clone made before the 2026-10-23 history rewrite), it now stops with recovery commands instead of warning, rebuilding the old tree and printing "Build complete" (direct commit 1ed154e).
+- **CI runs the race detector and shellcheck**: `go test -race -p 1` over every package with tests except `./server`, and `shellcheck -S warning` on `install.sh`, `update.sh`, `start.sh` and `scripts/backup.sh` (#144). The race run uses its own database (direct commit 0477751).
+
+### Upgrades
+
+- **Go 1.26.10** in `go.mod` (was 1.26.3), and **`golang.org/x/net` v0.62.0** (was v0.58.0), which raised x/crypto to 0.58.0, x/text to 0.43.0, x/sys to 0.49.0, x/sync to 0.24.0, x/mod to 0.41.0 and x/tools to 0.51.0 (#145).
+- **Node 22 in the runtime image**: NodeSource `setup_22.x` instead of the end-of-life `setup_20.x`, matching CI and the release workflow (#143).
+
+### Known issues
+
+- **The JWT signing key is not in the Docker volume**: the server writes `jwt.key` to the directory of the executable (`config.BaseDir()`), which is `/app` in the image, while the Dockerfile and `docker-compose.yml` comments say it lives in `/app/data`. The key therefore sits in the container's writable layer: recreating the container (for example `docker compose up -d --build` after an update) generates a new key and signs every user out. A key found at `data/jwt.key` is moved to `/app/jwt.key` on start and removed from the volume.
+- **The secret scrub has limits**: `os.Unsetenv` changes only the Go runtime's copy, so a process running as the same user can still read `/proc/<pid>/environ` of the server (and, in Docker, of PID 1, `start.sh`). Other variables that may carry credentials, such as `ARTEX_LLM_PROXY`, are not scrubbed.
+- **The LLM test and model-list endpoints still take `proxy` from the request**, so a saved key can travel through a request-supplied proxy when the base URL is plain HTTP.
+- **Postgres passwords with URL-special characters** (`@`, `/`, `#`, `?`) break the `ARTEX_PG_DSN` that `docker-compose.yml` builds by interpolation, and Compose interpolates `$` in `.env`.
+- **The build context includes local secrets**: `.dockerignore` does not exclude `.env`, `config.json` or `jwt.key`, so the build stage's `COPY . .` puts them in a build-stage layer of the local builder cache. They are not copied into the final image.
+- **Image supply chain**: the recon tools are downloaded at pinned versions but not checksum-verified, sqlmap tracks its default branch, and the Playwright packages are installed at `@latest`. Draft #127 proposes checksum verification.
+- **No Docker image is published for this release**: the release workflow's `docker` job only runs when `DOCKERHUB_ENABLED` is set, and it still downloads prebuilt binaries into `dist/` that the Dockerfile no longer uses. Build the image from the checkout with `docker compose up -d --build`.
+- **CI gaps**: `./server` is not run under `-race`; there is no `govulncheck` step and no `docker build` job. Four tests skip themselves (fresh-database or timing failures, see #9).
+- **Reported and not fixed in this release**: `list_task_credentials` emits an invalid `"required": [""]` schema that strict LLM providers reject (#130), and the MCP Streamable HTTP client fails against servers that only support protocol version 2025-11-25 (#131; fix proposed in #132).
