The runner's own `container.options` and the workflow's were joined into one string before parsing, so the host-escape filter added in https://gitea.com/gitea/runner/pulls/1058 dropped the administrator's options along with the workflow's. Setups that need `--device` or `--security-opt` from the config file had no way left to get them short of enabling privileged mode.
`NewContainerInput` now carries the two sources apart, as `RunnerOptions` and `WorkflowOptions`, down to the point where the filter runs. With privileged mode off, the host-escape fields are reset to what the runner's own options parse to on their own, so only the workflow's contribution is dropped.
Three further ways a workflow's options reached past its container, all resolved on the runner before anything reaches the daemon:
1. `--env-file` and `--label-file` name files that are read on the runner, so any file it could read became container environment or labels. Both are refused from a workflow now, and still serve the runner's own options.
2. A bare `--env NAME` was resolved from the runner's own environment by docker's validator. That lookup is gone, for every source. Use `runner.envs` or `runner.env_file` to pass a variable on.
3. A volume driver decides for itself what it mounts, and the local driver's `device=` option turns a name `valid_volumes` allows into a bind of any host path. A workflow's mounts may no longer carry one.
`--isolation`, `--volume-driver` and the two paths `--security-opt systempaths=unconfined` lands in were also missing from the fields a workflow may not set.
Last, the `--network and --net in the options will be ignored.` warning fired for every container, because the runner's own network mode is fed into the parsed options before the check runs.

`container.options` is parsed with docker/cli's `addFlags`, which omits the flags docker/cli registers on the `create` and `run` commands themselves. Those were rejected as unknown — most visibly `--platform`.
| Flag | Behavior | Why |
| --- | --- | --- |
| `--platform` | overrides the runner-wide container architecture | the only way to pick an image architecture per job, e.g. across a matrix |
| `--pull always\|missing\|never` | `always` forces a pull, `never` skips it | `force_pull` is runner-wide config today, with no per-job control |
Both are resolved in `NewContainer` because the image pull runs before the container is created and the two have to agree.
`--name`, `--quiet` and `--disable-content-trust` are now accepted and ignored, and `--use-api-socket` is rejected pointing at `container.docker_host`, so a valid `docker create` line no longer fails outright.
