feat(core): declare and enforce the manifest and agent-YAML schema - #178
Merged
Merged
Conversation
`global_controller.yaml` and the agent declarations were read with
yaml.safe_load and dozens of .get() calls spread over the controller, the
CLI and the stub generator. An unknown key was ignored, `replicas: "2"`
failed deep inside the instance manager once containers were being
launched, and an argument typed `List[str]` produced a stub that only
failed when the container imported it.
canyonos_core.schema declares every key, its type and its default, and
rejects what it does not know:
- errors.py declares SchemaViolation/SchemaError and renders a violation
as one `path:line: field: message` line, because the host CLI reads the
first ERROR: line out of the in-container deploy as the root cause.
- yaml_lines.py keeps PyYAML's line marks so a violation can point at the
line the key is written on.
- manifest.py parses the manifest into frozen dataclasses, collecting
every violation instead of stopping at the first. Unknown keys get a
suggestion from the keys that exist, a key valid for another service
type says so, and a type error quotes the value it found.
- agent_yaml.py restricts an argument's `type` to a builtin, since the
generated stub imports nothing and pastes the name in verbatim.
- validate_project() checks a manifest and every declaration it points
at, including that a declaration claims its agent's name.
`${VAR}` expansion and the root `.env` import move to
controller/utils/config_env.py so the schema checks values in the form
the Global Controller will act on: a port written `${API_PORT}` is an
integer by the time either looks at it. GlobalController keeps its
staticmethod names and behavior.
Also fixes _write_identity(), which read `.get("url")` straight off
`self.config["database"]`: an empty `database:` block parses as None, and
_database_url() already guarded for it.
examples/text2sql declares `provider: EC2` on every service but shipped
no `ec2:` block, so it cannot deploy and the schema now says so. It gets
the same `${ENV}`-placeholder block examples/portfolio already carries.
…thing `canyonos deploy` reaches the in-container `python -m canyonos_core.cli deploy`, which loaded the config with yaml.safe_load and went straight to generating stubs. A workflow with no `workflow_file` was warned about and skipped, and the deploy reported success with nothing built for it. validate_or_exit() runs the schema over the manifest and every agent declaration, at the top of cmd_deploy and again at the top of _run_build before the declaration index and before any generate_stub, protoc or subprocess call. Each violation is logged as its own single ERROR: line followed by a summary, since the host CLI turns the first such line into the deploy's root cause; the process then exits 1 rather than letting a traceback out. The requirements warn-and-drop goes away: a `requirements` that is not a list of strings is now a violation reported with its line, not a warning followed by a build that silently omits the packages. The EC2 preflight loses its duplicated required-key check for the same reason -- the schema already failed the deploy before anything was built -- and keeps the Docker and gRPC-stub checks it is really there for.
_platform_overrides() forced the platform pin over an app requirement it could not satisfy and printed a "Warning:" the deploy then ignored. The image installed cleanly and failed later, inside the container, on an import -- the exact failure the pins exist to prevent. An app asking for something *newer* still wins with its Note; an app asking for something the platform pin cannot meet now raises DependencyPinConflict, a SchemaError carrying a violation that names the manifest, `agents[<service>].requirements`, the spec it wanted, the platform pin it collides with, and the two ways out. _run_build checks every service's requirements before it builds the first one, so a project with two bad pins learns about both in one run instead of one per run, and reports them through the same one-line renderer the schema violations use.
The schema re-typed a value written as nothing but `${VAR}`, running the
expansion back through the YAML loader, so `api_port: ${PORT}` with PORT=9000
validated as the integer 9000. The Global Controller does no such thing: its
expansion is textual and the field holds the string "9000" at runtime.
`replicas: ${REPLICAS}` was the sharp edge -- it passed the schema as an
integer and then started a single replica, because _get_replica_placements()
only reads an int as a count.
Re-typing cannot be fixed by applying it more widely either: doing it across
the document would turn a password of "true" into a boolean. So the contract
is that a reference belongs in a string-typed field, and one in a numeric or
boolean field is a violation naming the reference as it is written:
agents[0].replicas: expected an integer >= 1, got '${REPLICAS}'
(environment references are only supported in string fields)
No example used a reference outside a string field. The config_env docstring
claimed both sides saw an integer; it now says what expansion really does.
Three things the same pass tidied, because they share these files:
- The field readers move to schema/_checks.py. agent_yaml.py was reaching
into manifest.py for five private helpers, and its `_AGENT_KEYS` meant
something different from manifest.py's; it is `_DECLARATION_KEYS` now.
- The eleven to_dict() methods go. Nothing in the runtime called them -- the
controller re-reads the YAML -- and 2c consumes the parsed model itself.
- validate_project() checked the declarations only when the manifest parsed,
so a project with a problem in each took two deploys to find them both.
Only the last step, binding each agent to the declaration that names it,
needs a manifest; the rest now runs either way.
A YAML parse failure is also collapsed onto one line with the line number
PyYAML marked, since a violation the host CLI reports has to be one line.
…to edit There is no `build` subcommand and cmd_deploy calls _run_build first thing, so validating in both was one call too many. The single gate lives in _run_build and now runs *before* _load_config, so a config file that is not YAML at all is rendered as a violation with its line rather than escaping as a yaml.safe_load traceback. It hands back the parsed manifest, which the dependency-pin check then walks by index, so a conflict reads `agents[0].requirements` like every other violation instead of naming the service and leaving the reader to find it. With the build checking every service's pins up front, generate_docker and generate_workflow_docker no longer need to know the manifest at all; their signatures go back to what they were. render_violation leaves out the field when the problem is the file rather than a key in it, which the parse-failure violation is: it used to render an empty one as a bare `: :`.
…a rejection Three things the schema got slightly wrong about its own messages and bounds. `otel.destinations[].timeout` is a duration, and the exporter has always taken a float for it, but the schema checked it with the integer reader -- so `timeout: 2.5` was rejected by the gate and then would have been accepted by the code it gates. A `_number` reader now covers it, with the same bounds the exporter enforces: int or float, not a bool, strictly positive. `_describe_rejected` (was `_describe_unsupported`) was wired into the integer and boolean readers only, so a string field whose reference expanded to nothing reported `redis.host: expected a non-empty string, got the string ''` -- true, and no help at all in finding which variable to set. Strings and string lists quote the reference as written now, like the numbers do. render_violation appended `:line` to an empty path, which would have rendered a pathless violation as `:5: field: message`. Nothing produces one today; the guard costs a word.

_run_build logged "Agent file not found" / "Workflow file not found", skipped the service and carried on, so a manifest pointing at a file nobody had written yet produced a deploy that exited 0 with that service simply absent from it. A project with no source root at all built nothing and said "No Docker images to build." Both are the silent pass this branch exists to remove, one layer further in. validate_project() takes an optional `source_dir`. Given one, an agent's `entrypoint` and a workflow's `workflow_file` must exist under it: config/global_controller.yaml: agents[0].entrypoint: /home/me/app/agents/example_agent.py does not exist A source root that is missing entirely is one violation naming the directory rather than one per service, since the cause is the same for all of them. Left out, nothing on disk is checked, so callers that only have the YAML -- the 2c validator among them -- are unaffected. _run_build passes its own source root, and the two now-unreachable skips are gone. The layout it shares with the gate is computed once, in _project_layout() (which _declarations_dir() becomes), rather than twice from cwd. The `if not entrypoint:` / `if not workflow_file:` / `if not image:` warnings further up that loop are unreachable for the same reason -- the schema makes all three required -- but they are left alone here as cheap guards.
The violation quoted the absolute path it had joined, so a reader had to translate /home/me/proj/agents/example_agent.py back to the `entrypoint: agents/example_agent.py` they had written. Paths are rendered relative to where the build runs -- the project root -- like every other violation, and left absolute only when they fall outside it, where there is no shorter honest form. config/global_controller.yaml: agents[0].entrypoint: agents/example_agent.py does not exist .car/config/global_controller.yaml: agents: the project source directory .car/app does not exist, ... Also drops the three `if not entrypoint/workflow_file/image` warn-and-skip guards left in the build loop. The schema requires all three and has checked each one by the time that loop runs, so they were unreachable, and a dead skip in a loop whose whole point is that it no longer skips anything is the wrong thing for the next reader to find.

_run_build validated the manifest with `${VAR}` refs expanded, then threw the
parsed model away and re-read the raw YAML for the build. A reference in a
string field passed the gate in its expanded form and reached the generators
as the literal: `entrypoint: ${AGENT_FILE}` validated as a real file and then
failed in shutil.copy2 on one called `${AGENT_FILE}`, and a requirement
written that way went into requirements.txt as `${...}`.
cli._load_config now imports the root `.env` and expands refs through
controller/utils/config_env.py, the helper the schema and the Global
Controller already share, so there is one expansion path and the build acts
on what was validated. The Global Controller keeps its own loader and is
unchanged.
PyYAML keeps the last value of a duplicated key without a word, so `replicas:` written twice in one service deployed whichever came second, and a second `agents:` block replaced the first entirely. Both passed the schema, since by the time it looked there was only one key left to check. The line-tracking loader now refuses a mapping that repeats a scalar key, raising at the second occurrence, so it renders as one violation pointing at the line to delete: global_controller.yaml:5: is not valid YAML: found duplicate key 'replicas' (first set on line 4) in "...", line 5, column 5 Keys are compared by tag and text, so `1` and `"1"` -- an int and a string, two different keys to YAML -- are not mistaken for a repeat. The manifest and agent declarations both load through this loader, so both are covered.
_platform_overrides matched an app requirement to a platform pin by lowercasing the name, but pip treats `grpcio_tools`, `Grpcio-Tools` and `grpcio.tools` as one package. `grpcio_tools<1` missed the `grpcio-tools` pin, so instead of failing the build as a conflict it was silently overridden -- the exact outcome the conflict check exists to prevent. Both sides are normalized with packaging's canonicalize_name (PEP 503), so every spelling of a pinned package is compared against its pin. The newer- wins path is unchanged and matches the same way.
Conflicts:
- cli.py _load_config: both kept. The root .env import and ${VAR} expansion
run first, then #116's structural checks, unchanged, on the expanded config.
- global_controller.py _write_identity: main's payload. #104 dropped
database_url from it, which removes the line the `or {}` guard protected.
The config_env delegation merged cleanly.
- test_global_controller_identity.py: main's version. The empty-database
test covered that same line.
The gate in _run_build still runs before _load_config. #116 overlaps with it:
- #116's missing-sources block in _run_build is removed. The gate already
reports a missing entrypoint or workflow_file, one line per violation.
That block also required an `entrypoint` on `type: database` services, so
on main any manifest with a database fails to build.
- The schema now rejects everything #116's _load_config checks reject, so
none of those RuntimeErrors can escape as a traceback once the gate has
passed: ports must be 1-65535, a local workflow may not have replicas > 1,
and resources are positive numbers (cpu 0.5 now passes, gpu 0 fails).
test_build_fails_when_stub_cannot_be_generated now asserts the gate's
exit 1 instead of #116's RuntimeError.
- Provider case is left strict: `LOCAL` is still rejected at the gate even
though _load_config would normalize it.
The schema declares #108's new top-level `logs` flag as a boolean, default
true, the same default both runtimes read. The portfolio example set
`env_file: .env` twice. PyYAML silently kept the second copy; the
duplicate-key check rejects it, so the second copy is removed.
#116 made `provider` case-insensitive in cli._load_config, rewriting `LOCAL` or `ec2` to the `local` / `EC2` the runtimes compare against. The gate runs first and still demanded the exact spelling, so the merged path rejected what #116 set out to accept. The schema now takes any casing and normalizes the parsed value the same way. A lowercase `ec2` still requires the `ec2:` block and an instance_type, and a real misspelling is rejected as before. Nothing has read the top-level `database:` block since #104 moved telemetry under `otel:`, so accepting it silently would leave a user believing their runs were recorded there. It is rejected with a message saying why, not the generic unknown-key text: database: is no longer used; telemetry is configured under otel: -- remove it DatabaseSpec and Manifest.database go with it. No example still carried the key.
`doctor.py` still imported `REDIS_PORT` from `dashboard_stack`, which #141 removed when the local Redis port became configurable, so `import cli` failed and the `canyonos` entry point could not start at all. The Redis check now resolves the port the way `dashboard_stack` does, `local_redis_port(default_config_path())`: the host port the local node's Redis is actually published on. The hint names that port instead of a hardcoded 6379. A new test imports `cli` in a fresh interpreter, so the entry point cannot break again unnoticed; inside the suite, another test's imports had let the broken one pass.

YAML spells infinity and NaN `.inf` and `.nan`, and both are floats, so a `resources.cpu: .nan` or an otel `timeout: .inf` passed the number check. An integer too long for a float got further still: it passed the bounds check and then raised OverflowError converting on the way out, escaping the gate as a traceback. The number reader converts once, inside a try, and requires the result to be finite; anything else is an ordinary violation. Integer fields already refused all three, since none of them is an int, and now have tests saying so.
The source-path check used posixpath.isabs plus a drive-letter test, so `\outside\agent.py` and `\\server\share\agent.py` read as relative names inside the project and passed. They are now rejected like any other path anchored outside the project, whichever OS the manifest was written on. The leading backslash is tested explicitly because newer Pythons no longer treat a drive-relative `\x` as absolute.
`ec2.security_group_ids: []` passed the required check, since the key was present. The ec2 reader then saw an empty tuple, returned no Ec2Spec and recorded no violation, so an EC2 service validated with Manifest.ec2 None. A required string list now has to be non-empty. Only security_group_ids is required; `requirements` is optional and may still be an empty list, and a test pins that.
_platform_overrides kept one Requirement per canonical name, so a package listed twice counted only by its last line. `["protobuf<5", "protobuf>=7"]` read as a request for something newer and built; the same two lines in the other order failed as a conflict. Repeated requirements for one package are now combined into a single specifier set before the comparison, since only their intersection can be installed. The request counts as newer only if every bound that rules out the pin is a lower bound above it. One upper bound below the pin makes it a conflict, in either order. requirements.txt is unchanged: it still carries each line as the app wrote it.
`protobuf>6.33.5` rules out the platform pin and nothing older, so every version it allows is newer, the same as `>=` above the pin. The newer-request test demanded a bound past the pin for every operator, so `>PIN` was reported as a conflict and failed the build. `>` now counts at the pin itself. `>=PIN` and `==PIN` include the pin and still keep it quietly; tests pin both sides.

Almost all of the comments I made were about small gaps and holes in the code. Would be open to hardening the actual code instead of these checks so more values are able to be accepted, your judgement tho

write_agent_specs read the raw YAML, so a service named ${AGENT_NAME}
wrote the Redis key agent:${AGENT_NAME}: while the schema and the build
saw the expanded name. cli, the Global Controller and the spec writer now
share config_env.load_config.
generate_stub read the raw YAML, so a blank `arguments:`, `functions:` or
`type:` passed the schema and crashed the generator, and a ${VAR} the schema
expanded was written into the stub literally. The stub, the Docker context
and the build's name lookup now all use load_agent_declaration.
Every name the stub writes as source must be a Python identifier; an
argument cannot be `self` or repeat. A type may be any annotation built
from builtins (`list[str]`, `dict[str, int]`, `int | None`, `None`).
The schema kept its own copy of the destination contract and it drifted: it rejected GRPC, HTTP and http/protobuf, which the exporter accepts, and let through numeric header values, an empty list and names that collide once trimmed, which the exporter rejects at runtime. The rules now live in schema/otel_destinations.py and both the manifest schema and the exporter use them.
…ssing
A required field whose variable is unset kept the literal ${VAR} and
passed, so examples/text2sql validated with no EC2_* set and the literal
region reached boto3. A required field or list item that still names an
unset variable is now reported as such.
The required ec2: keys were also enforced for projects where no service
uses EC2; only an EC2 deploy reads the block, so only then is it checked
beyond its key names. The optional ec2 fields are checked even when a
required one is missing.
Both are durations the runtimes sleep or wait on, and local_controller reads CANYONOS_POLL_INTERVAL as a float; the schema required an integer.
…pins - The schema now parses each requirements entry as one PEP 508 requirement. An option line like `-r deps.txt`, or two packages in one entry, used to skip the pin check and be written verbatim into requirements.txt. - Environment markers are evaluated for the image (Python IMAGE_PYTHON_VERSION on Linux), so a requirement that does not apply there no longer counts as a conflict. - `!=PIN` next to a lower bound above the pin is still a newer ask.
local_redis_port returned whatever the manifest held, and doctor's int()
crashed on `abc`, `${VAR}` or null, and on an agents entry that is not a
mapping. It now returns the default port unless the config holds a usable
one, which the dashboard's CANYONOS_REDIS_PORT also relies on.
…project The path checks only looked at what the manifest wrote, so a symlink inside the project pointing elsewhere passed, and the build's copy2 followed it into the image.
… parse - A service with an unknown type, or without a name, now has the rest of its fields checked too; before, the first problem hid the others. - The YAML loader records the line of each list item, so a service, destination, function, argument or requirement that is wrong points at its own line instead of line 0 or the list's key. - check_project returns the parsed manifest with its violations, so validate_or_exit no longer parses the manifest a second time.

- An argument type must evaluate, so `int[str]` or `None | None` is rejected instead of failing when the stub's `def` runs. - An agent or argument named Future, inspect or isinstance is rejected; it shadowed the name every generated method body reads. - A bad `env` entry is named with its key and line, not "got a mapping". - A dependency conflict carries the line of the requirement to edit. - A `project_id:` left null is filled in place instead of a second key being appended, which the next build rejected as a duplicate. - Markers are evaluated for the image's architecture, taken from the same CANYONOS_DOCKER_PLATFORM the build uses; a marker on a value the image does not fix, such as the Python patch version, is checked, not guessed from the machine running the build.

What was done
Config mistakes are now caught and explained before anything is built, instead of failing mid-deploy.
Details
Core now checks global_controller.yaml and the agent YAMLs against a schema before any deploy step runs.
• Early validation: Mistakes like unknown or duplicate keys, wrong types, or missing required blocks are reported as clear errors that name the file, line and field. This happens before any build step.
• No more silent skips: If an entrypoint, workflow_file or app/ is missing, the deploy now fails. Before, the service was skipped and the deploy still showed green.
• ${VAR} only in string fields: Using one in a numeric field is now an error.
• Dependency conflicts fail the build: If an app pins a package below the platform's version, the build stops with the exact conflict. Before, it quietly forced the platform version and the image crashed at startup.
• Older checks moved into the schema: Port range, replicas and resources checks from #116 now give file and line errors instead of tracebacks. The unused database: key is now rejected.
Not in this PR: the runtime (
GlobalController, the runtimes) still consumes the raw dict; the schema gates the deploy. Follow-ups: list-formreplicas(handled by the controller, broken in the instance manager) is rejected by the schema;.env.examplefor the EC2 examples.How to test it
A wrong type fails before anything is built:
stubs/stays empty; no Dockerfile or image is produced. Onmainthe same deploy launched containers and failed inside the instance manager.A file the manifest points at but the project does not hold (
rm agents/example_agent.py):A pin the platform cannot satisfy (
requirements: ["protobuf<5"]on an agent):requirements: ["protobuf>=7"]still wins with itsNote:line, unchanged.Other things to poke at:
replias: 2→unknown key 'replias' (did you mean 'replicas'?);replicas:written twice in one service →found duplicate key 'replicas' (first set on line N);entrypoint:on atype: workflowentry →key 'entrypoint' is not valid for type 'workflow';replicas: ${REPLICAS}→ rejected, set or unset;redis_port: 70000→ one line, no traceback;type: List[str]on an argument in an agent YAML → rejected with file, line andagent.functions[0].arguments[0].type;provider: EC2withoutec2:→ rejected before the build; a YAML syntax error → one line with the file and line, no traceback.Summary by CodeRabbit
