fix

For pull_request_target tasks, use the pull request head SHA from the event payload as the default checkout ref so actions/checkout resolves the submitted PR content instead of the base branch tip.

-## Job log line format
-
-Gitea stores one log row per line and its web UI decodes the payload, so getting the encoding
-wrong never fails a test here, it only shows up in the browser.
-
-**A row cannot contain a real newline.** `FormatLog` rewrites `\n` to a literal backslash-n and
-truncates at 64 KiB on a byte boundary.
-
-**The payload of a line starting with a recognised prefix is decoded**, with the escape set
-depending on the prefix:
-
-| prefix | decodes |
-| --- | --- |
-| `##[error]` `##[warning]` `##[notice]` `##[debug]` `##[group]` `##[endgroup]` `##[add-matcher]` | `%25` `%0D` `%0A` `%3B` `%5D` |
-| `::error::` `::warning::` `::notice::` `::debug::` (with or without ` key=value` properties), `::group::` `::endgroup::` `::add-matcher::` | `%25` `%0D` `%0A` |
-| `##[command]` `[command]`, or no recognised prefix | nothing |
-
-### Rules
-
-- **Emitting a command line?** Escape the payload with `runner.EscapeCommandData`. One escaper
-  covers both forms: it escapes `%` first, so a literal `%3B` becomes `%253B` that the extra
-  `##[…]` rules cannot match, and a raw `;` or `]` is never decoded. It is also what makes
-  multi-line work, `\n` becomes `%0A` and the UI turns it back into a line break.
-- **Forwarding a command from step output?** Leave the payload alone, it arrived escaped and is
-  decoded once. Decoding here double-decodes and destroys multi-line.

 Mount a volume on `/data` if you want the registration file and optional config to survive container recreation (see [scripts/run.sh](scripts/run.sh)).
 
-> **`/data` does not hold the image cache.** It is the runner's working directory and contains only the `.runner` registration file and, optionally, your config file. Images pulled for jobs live in the *Docker daemon's* data root, which for the `dind` flavours is inside the container (`/var/lib/docker`, or `/home/rootless/.local/share/docker` for `dind-rootless`). To keep the image cache across restarts, give that path its own volume as well — otherwise every new container re-pulls the job images. With the `basic` flavour the images live on whichever daemon you point the runner at, so there is nothing extra to persist.
-
 ### Image flavours
 
 The image is published in three flavours, all built from the single multi-stage [Dockerfile](Dockerfile) in this repository. They differ only in how a Docker daemon is made available to the jobs the runner executes; the `gitea-runner` binary inside them is identical.
@@ -123,167 +121,49 @@ Two processes have to run side by side here (the Docker daemon and the runner),
 
 Same idea as `dind`, but built on `docker:dind-rootless` so the bundled daemon and the runner run as an unprivileged user (`rootless`, UID 1000) rather than `root`. `DOCKER_HOST` is preset to `unix:///run/user/1000/docker.sock` so the runner talks to the rootless daemon. This reduces the blast radius compared to the privileged `dind` flavour, but rootless Docker carries the usual rootless limitations (networking, cgroups, storage drivers, and some operations that need additional host configuration such as `/etc/subuid` / `/etc/subgid` mappings and unprivileged user-namespace support).
 
-> **The UID is fixed at 1000.** It comes from the `rootless` user baked into the upstream `docker:dind-rootless` base image, and the bundled daemon always listens on `/run/user/1000/docker.sock` inside the container, so running this flavour as a different user (`--user 1001`) does not work. If you need the runner to talk to a *host* rootless daemon that runs under some other UID, use the `basic` flavour instead and bind-mount that daemon's socket (see [examples/vm/rootless-docker.md](examples/vm/rootless-docker.md)); pointing `DOCKER_HOST` at a host socket from inside `dind-rootless` will not work. Changing the UID otherwise means rebuilding the image from a base with a different `rootless` user.
-
 > **Note on Podman:** these images target the Docker daemon. The bundled `dind`/`dind-rootless` daemons are `dockerd`, not Podman, and the `basic` flavour expects a Docker-compatible socket. Running them under rootless Podman is not a supported configuration, though pointing the `basic` flavour at a Podman socket that emulates the Docker API may work for some workloads.
 
 ### Configuration
 
-The runner reads a YAML file. Without one, every option keeps its default.
+The runner is configured with a YAML file. Generate a starting point (this matches what ships in the tree):
 
 ```bash
-./gitea-runner config init             # write config.yaml, with no option set
-./gitea-runner config generate | less  # read what the options do
-./gitea-runner -c config.yaml daemon   # -c also works on register and cache-server
+./gitea-runner generate-config > config.yaml
 ```
 
-`config generate` prints [config.example.yaml](internal/pkg/config/config.example.yaml). Every value in it is commented out, so copy the lines you want to change into your own file and uncomment them.
-
-#### Editing a config file
-
-`config` edits a file in place, which is handy in provisioning scripts:
+Pass it with `-c` / `--config` on any command that loads configuration (`register`, `daemon`, `cache-server`):
 
 ```bash
-./gitea-runner config set runner.capacity 4
-./gitea-runner config set runner.timeout 90m  # written as 1h30m0s
-./gitea-runner config set runner.envs.MY_VAR value
-./gitea-runner config add runner.labels 'ubuntu:docker://node:22'
-./gitea-runner config remove runner.labels 'ubuntu:docker://node:22'
-./gitea-runner config get runner.labels
+./gitea-runner -c config.yaml register
+./gitea-runner -c config.yaml daemon
+./gitea-runner -c config.yaml cache-server
 ```
 
-A key is its dotted YAML path. An unknown key, a value of the wrong type, or `add`/`remove` on anything but a list is refused before the file is touched. `set` replaces a whole list when you give it several values.
+Every option is described in [config.example.yaml](internal/pkg/config/config.example.yaml) (the same content `generate-config` prints).
 
-An edit keeps the comments and the key order of the file. Indentation becomes two spaces, and a blank line between two values is dropped.
+#### Without a config file
 
-`config get`, `set`, `add` and `remove` use `config.yaml` (or `config.yml`) from the working directory, then from the directory of the binary, and print their choice to stderr. `config init` writes `config.yaml` in the working directory, and refuses to overwrite an existing config without `--force`. Pass `-c` for another path.
+If you omit `-c`, built-in defaults apply (same as an empty YAML document). A small set of **deprecated** environment variables can still override parts of that default config, but **only when no `-c` path was given**; they are ignored if you use a config file:
 
-#### Environment variables
-
-Earlier releases let a few environment variables (`GITEA_DEBUG`, `GITEA_TRACE`, `GITEA_RUNNER_CAPACITY`, `GITEA_RUNNER_FILE`, `GITEA_RUNNER_ENVIRON`, `GITEA_RUNNER_ENV_FILE`) override parts of the config. They are gone, use the YAML file for all settings. The Docker images still read their own variables, such as `RUNNER_STATE_FILE`, see [scripts/run.sh](scripts/run.sh) and the container documentation below.
-
-### Labels
-
-Labels decide **which jobs a runner accepts** and **how it runs them**. A job's `runs-on` is matched against the runner's label names; the first match wins and selects the execution environment for that job.
-
-A label is written as:
-
-```text
-<name>[:<schema>[:<args>]]
-```
-
-| Part | Meaning |
+| Variable | Effect |
 | --- | --- |
-| `name` | The name a workflow refers to in `runs-on`, e.g. `ubuntu-latest`. |
-| `schema` | Either `docker` or `host`. Defaults to `host` when omitted. |
-| `args` | Only used by the `docker` schema: the image to run the job in. |
+| `GITEA_DEBUG` | If true, sets log level to `debug` |
+| `GITEA_TRACE` | If true, sets log level to `trace` |
+| `GITEA_RUNNER_CAPACITY` | Concurrent jobs (integer) |
+| `GITEA_RUNNER_FILE` | Registration state file path (default `.runner`) |
+| `GITEA_RUNNER_ENVIRON` | Extra job env vars as comma-separated `KEY:VALUE` pairs |
+| `GITEA_RUNNER_ENV_FILE` | Path to an env file merged into job env (same idea as `runner.env_file` in YAML) |
 
-Two schemas are supported:
-
-- **`docker://<image>`** — the job runs inside a container created from `<image>`:
-
-  ```text
-  ubuntu-latest:docker://docker.gitea.com/runner-images:ubuntu-latest
-  ```
-
-- **`host`** — the job's steps run directly on the machine the runner is on, using the tools installed there:
-
-  ```text
-  macos:host
-  ```
-
-So with the labels
-
-```text
-ubuntu-latest:docker://docker.gitea.com/runner-images:ubuntu-latest,macos:host
-```
-
-a workflow with `runs-on: ubuntu-latest` is executed in the `runner-images:ubuntu-latest` container, and one with `runs-on: macos` is executed directly on the host.
-
-Names may themselves contain a colon (for example `pool:e57e18d4-10d4-406f-93bf-60f127221bdd`); only `host` and `docker` are treated as schemas.
-
-If a job's `runs-on` matches none of the runner's labels, the job still runs, in the default `docker.gitea.com/runner-images:ubuntu-latest` image. Images maintained for this purpose are listed at [gitea/runner-images](https://gitea.com/gitea/runner-images).
-
-Labels are chosen at registration time (`--labels`, or the interactive prompt) and can be changed afterwards by editing `runner.labels` in the config file, or in the Gitea UI under the runner's settings.
+Prefer a YAML file for all settings.
 
 #### Registration vs config labels
 
 If `runner.labels` is set in the YAML file, those labels are used during `register` and the `--labels` CLI flag is ignored.
 
-The `daemon` command also accepts `--labels` (which defaults to the `GITEA_RUNNER_LABELS` environment variable), so the labels of an already registered runner can be changed without deleting its registration file. The most explicit source wins:
-
-```
---labels / GITEA_RUNNER_LABELS   >   runner.labels in the config file   >   labels in the .runner file
-```
-
-Whenever the resulting labels differ from the ones in the registration file, they are written back to it and re-declared to the Gitea instance on startup.
-
-> **Note:** A runner that only exposes `host` labels still needs access to a Docker daemon (e.g. a mounted `/var/run/docker.sock`) whenever a job uses a `docker://` action or a service container. `host` labels only change where the job's own steps run; container-based steps and actions are still executed with Docker.
-
-#### Service containers
-
-A job's `services` are started before its steps run. When a service's image or its `options` declare a healthcheck, the runner waits for it to report healthy, so a workflow does not have to poll for its own services:
-
-```yaml
-services:
-  postgres:
-    image: postgres:17
-    options: >-
-      --health-cmd pg_isready
-      --health-interval 5s
-      --health-retries 10
-```
-
-A service that reports unhealthy fails the job right away, with its container log. One that never becomes healthy fails it after `container.service_ready_timeout` (default `5m`, negative disables the wait). A service that exits without declaring a healthcheck only gets its log and a warning.
-
-A job in a container reaches a service by its id on the job network, on the port the service listens on, for example `psql -h postgres -p 5432`. The started containers also fill the `job` context: `job.container.{id,network}` and `job.services.<id>.{id,network,ports}`, where `ports` maps a container port to the host port Docker published it on, for the services that publish one.
-
-Unlike GitHub, a job whose steps run on the host (a `host` label without `container:`) starts no service containers, so `job.services` and `job.container` stay empty. Give such a job a `container:` when it needs services.
-
-#### Proxy
-
-Set these variables in the runner's environment, with systemd `Environment=`, `docker run -e`, or Kubernetes `env:`:
-
-```sh
-http_proxy=http://proxy.example:3128
-https_proxy=http://proxy.example:3128
-no_proxy=gitea.internal,.example.local
-```
-
-The runner uses them for its own requests and gives them to every job, in lower and upper case.
-
-These hosts are added to `no_proxy` for jobs, so they are always reached directly:
-
-- the cache server
-- `localhost`, `127.0.0.1` and `::1`
-- the job's service containers
-- the Docker daemon, when it is reached over `tcp://`
-
-Gitea is not added. Add it to `no_proxy` yourself if it should be reached directly.
-
-To change a value for one job, set it in a step's `env:` or in the job's `container.env`. Setting it at workflow or job level has no effect. To change it for the whole runner, set it in `runner.envs`. A `no_proxy` set there is added to the list above instead of replacing it.
-
-Images are pulled by the Docker daemon, which needs its own proxy setting. In the `dind` images the daemon runs in the same container and reads the variables above. For any other daemon, see [the Docker documentation](https://docs.docker.com/engine/daemon/proxy/). The runner logs a warning at startup if it has a proxy and the daemon does not.
-
-Dockerfile actions are built with these variables as build arguments, so their `RUN` steps can reach the network.
-
-A password in a proxy URL is hidden in job logs. Any step can still read it, because the step is given the proxy URL in its environment.
-
 #### Caching (`actions/cache`)
 
 Each runner starts its own cache server automatically. Cache entries are local to that runner — runners do not share a cache by default.
 
-**Cache service v2**
-
-`actions/cache@v4.2` and later can use the *cache service v2* API. The runner serves it from the same store as v1, on by default, and it works with `external_server`. Turn it off with:
-
-```yaml
-cache:
-  v2: false
-```
-
-Those actions refuse any host they do not take for GitHub. Rather than misreport the server URL, the runner edits that check out of the action's own bundle and keeps the untouched copy beside it; a bundle it does not recognise is left alone and keeps to v1. The same edit lets the stock `actions/upload-artifact` and `actions/download-artifact` work from `v4.4.0` on, without the `gitea-upload-artifact` fork.
-
