On the live cluster ax created the Task before its Workspace in the same apply
and the runner saw an empty AX_WORKSPACES_YAML. Tests now find rendered
documents by kind and name, not position. ops/ax/smoke-run.sh renders a
model-free repo-facts Run with the current runner digest and executes it
through the reconciler.

Agent Substrate's golden-snapshot boot runs the same image with the same task env,
so the runner no longer starts its command by itself: after the workspaces are
ready it waits for POST /ousast/v1/start (run/task checked, once per boot, refused
after a delivered run). The reconciler sends it through svc/atenet-router with
ate-target-actor, which never addresses the golden actor (plane/router.py), and the
bound Model's secretKey variable travels only in that body, into the child's env.

On the live cluster ax hands AX_TASK_YAML with metadata.creationTimestamp and a
status block; the strict authoring schema rejected it, readiness never turned
green and every resume timed out. Other unknown fields still fail. up.sh retries
the first resume while the golden snapshot builds.

The first live run on the local ax cluster and ax's source (docs/runner.md,
docs/sandbox.md, internal/controller/reconciler.go, internal/server/server.go)
showed a lifecycle the task-3/4 code did not model:
- `ax apply` creates a Task Suspended (Ready=False, TaskSuspended); it runs only
after `ax resume task`. The first resume of a new image can fail with
DeadlineExceeded while Agent Substrate builds the golden snapshot, and ax's
server then stores phase Failed; a later resume succeeds.
- ax has no Completed phase and never reads a command's exit back.
- The runner is PID 1 and must keep serving after the command exits; stop and
suspend deliver SIGTERM, to be forwarded to the command's process group.
Our runner imported the task in-process and exited, which stopped the
container ("Container guest is stopped") and made every resume time out.
- ax's controller probes /readyz?check=workspace; the query string made our
handler answer 404.
Runner (Req 4.1-4.4): spec.command runs as a child
`python -m openultrasast.plane.tasks.<name>` in its own process group, cwd the
first workspace, AX_METADATA_URL set; ax's metadata paths are served. After the
child exits the runner reads summary.json (a crash without one becomes failed
with the exit code and stderr tail), delivers the output directory, writes
/workspace/.ousast-state/<task>.done.json and serves until SIGTERM (forwarded
to the group, SIGKILL after OUSAST_TERM_GRACE, exit 0). A boot with the marker
never reruns the command; a failed delivery is retried alone. Workspaces are
prepared on the first boot only. AX_RUNNER_EXIT_AFTER_COMMAND=1 is the
unit-test escape.
Reconciler (Req 2.2, 2.3, 3.1-3.3): `ax resume task` after apply, retrying
DeadlineExceeded/Unavailable with backoff up to OUSAST_RESUME_TIMEOUT (900 s);
completion is the artifact delivery; Failed after a resume went through, a
vanished task, or no delivery within OUSAST_TASK_TIMEOUT (7200 s) fail the
task with ax's condition message; `ax delete task` follows. Ax gains resume()
and phase() returns the condition message. doctor moves to plane/doctor.py
(tasks.md task 0 allows the sibling) to keep reconciler.py under 500 lines.
Tests: the fake ax follows the real lifecycle (Suspended, a failing first
resume that leaves Failed, Running forever, delivery only after a resume went
through), plus Failed-with-message, vanish, resume-timeout and task-timeout
scenarios; runner tests cover the child's cwd/group/metadata URL, stay-up and
SIGTERM in a real subprocess, SIGKILL of a SIGTERM-ignoring group, and the
marker. The opt-in live test now checks resume, Running, suspend and a second
resume instead of a Completed phase. design.md and tasks.md state the
lifecycle; the module audit manifest counts plane.doctor.

Requirement 1.1 (Task/Workspace/Model use only fields ax documents) and
Requirement 1.4 (no ax field repurposed) were violated: manifests accepted
metadata.namespace and a Workspace git `commit`, and the reconciler dumped
every git field into what `ax apply` receives.
Facts from ax's source (pkg/apis/v1alpha1/ax.proto, internal/workspace/setup.go):
- ObjectMeta is `name` and `atespace` (plus server-set creation_timestamp);
no `namespace`, no `annotations`.
- GitRepo is `name`, `repo`, `branch`, `dir`, `depth`; no `commit`.
- The API server decodes with protojson.UnmarshalOptions{}: an unknown field
is an error at `ax apply` (confirmed on the live cluster: a rendered
Workspace+Model applied cleanly; the same Workspace with `commit` was
refused with `unknown field "commit"`).
- ValidateModel checks only metadata; any spec.provider string is accepted.
Changes:
- manifests: metadata takes `name`, `atespace`, `annotations` (our extension,
never sent to ax); git entries take exactly ax's five fields (depth int);
`commit` in spec.git is rejected with a pointer to the new Workspace
annotation `openultrasast.io/git-commits: "<git name>=<40-hex>,..."`,
validated for unknown git names and non-hex shas.
- reconciler: rendered docs carry only ax fields; each bound Workspace's pins
reach the Task as env OUSAST_GIT_PINS = {"<workspace>/<git name>": "<sha>"}.
A test walks every rendered doc against ax's field lists.
- runner: pins come from OUSAST_GIT_PINS; git is fetched as setup.go does
(init/remote/fetch with --depth when depth > 0/checkout FETCH_HEAD, default
branch main, cloneDestination's dir and placeholder-name rules), then the
pin is checked out. A pinned entry without a branch fetches the commit.
- workspaces: emits the annotation, `dir: repo` and `depth: 1` instead of
`commit`, so generated case workspaces keep <path>/repo at depth 1.
- design.md: ax field names verbatim; pins and model binding as stripped
openultrasast.io/* annotations carried to the task by env.

ai-service-plane task 3, Requirements 4.1-4.4 (with 2.2 and 2.3 honoured by the
exit-code contract):
- src/openultrasast/plane/runner.py: the ax-task-runner entrypoint. Reads the Task
from AX_TASK_YAML and the bound Workspaces from AX_WORKSPACES_YAML (task-1 loaders),
serves /healthz and /readyz on port 80 (AX_RUNNER_PORT; 0 picks a free port,
AX_RUNNER_HTTP=0 disables it for unit tests), materialises each workspace at its
bound path (spec.files verbatim; spec.git at <path>/<name>, exported from the
OUSAST_CASE_CACHE checkout whose origin matches, else a shallow clone at the pin;
a repo already present on a resumed volume is kept) and only then answers 200 on
/readyz. Runs spec.command by importing openultrasast.plane.tasks.<name> with the
remaining elements as argv; sets OUSAST_WORKSPACE_DIR from the first binding when
the Task's env leaves it unset. A crash writes summary.json with status failed and
the traceback. When OUSAST_ARTIFACT_URL is set, the whole OUSAST_OUTPUT_DIR is
POSTed as an uncompressed tar (Content-Type application/x-tar, X-Ousast-Task,
X-Ousast-Run) with three attempts and backoff; a failed delivery rewrites
summary.json to failed and exits 2. Exit codes: done 0, failed 2, unfinished 3.
- plane/Dockerfile.runner: python:3.12-slim + git, `pip install .` (no extras), a
shell wrapper at /usr/local/bin/ax-task-runner exec'ing the module; built and
loaded into kind by ops/ax/up.sh, not by the tests.
- tests/test_plane_runner.py (+ tests/plane_stub_task.py registered as the task
module): env contract on a files workspace, readyz 503 then 200, delivery to a
local receiver with the headers and tar checked, delivery failure -> failed and
exit 2 after three attempts, crash -> failed with traceback, exit codes per
status, case-cache export at the pin, shallow-clone fallback, resume keeps the
checkout.
- model/audit.py: SPEC_OWNED row for plane.runner; module-audit measurement
regenerated (122 modules, no orphans, note kept).
