The Client public API table in ARCHITECTURE.md listed eight methods, six of which do not exist on the only impl Client in the workspace, and it contradicted the sentence directly beneath it. The CLI table invented a top-level ping command and a model list-files subcommand while omitting init, list, status, clear-all, stats and api send. Both tables are rebuilt from the clap definitions and the real method signatures.

The registry CR name format in metadata.md omitted the provider segment, so both the format string and the worked kubectl example named resources that do not exist. The pre-0.5.0 name-only form is now described separately as the migration path it is. ARCHITECTURE.md described the Redis key as mx:model:{name} when it is mx:model:{provider}:{name}, and claimed the registry CRs share a sanitize_model_name helper with the P2P CRs. There is no shared helper: the registry has sanitize_registry_name and P2P has its own sanitize_model_name.

CLI.md documented a default config path the -c loader never reads. That path is real but belongs to the separate cache-config store written by model init, so both are now described distinctly. DEPLOYMENT.md documented MX_STATUS_TTL_SECS, which has no consumer anywhere. The k8s_service_sources example named MX_S3_URI instead of MX_MODEL_URI. The helm README gave the cache directory default as /app/cache where the chart sets /root.

Summary by CodeRabbit

  • Documentation
    • Updated architecture and CLI documentation to reflect current commands, cache management, revision pinning, and configuration discovery.
    • Clarified provider-qualified Kubernetes cache naming and backward-compatible lookup behavior.
    • Removed outdated deployment settings and corrected environment variable guidance for S3 configuration.
    • Updated the documented default cache directory.

The Client public API table in ARCHITECTURE.md listed eight methods, of which
six do not exist on the only impl Client in the workspace, and it contradicted
the sentence directly beneath it. The CLI table invented a top-level ping
command and a model list-files subcommand while omitting init, list, status,
clear-all, stats and api send. Both tables are rebuilt from the clap
definitions and the real method signatures.

  mx:model:{provider}:{name}, with the name-only key retained as legacy

Review Change Stack

Walkthrough

The documentation now describes provider-qualified registry names, current client and CLI APIs, updated configuration-file discovery, and current cache and deployment settings.

Changes

Documentation alignment

Layer / File(s) Summary
Registry and CRD naming
docs/ARCHITECTURE.md, docs/metadata.md
Documents provider-qualified Redis keys and Kubernetes CRD names, including legacy name-only lookup compatibility.
API and CLI references
docs/ARCHITECTURE.md
Updates the client API and CLI command references with current cache, health, model, API, and revision-aware operations.
Configuration and deployment documentation
docs/CLI.md, docs/DEPLOYMENT.md, examples/k8s_service_sources/README.md, helm/README.md
Updates configuration-file discovery, cache configuration, environment variables, S3 settings, and the Helm cache-directory default.

Estimated code review effort: 2 (Simple) | ~10 minutes

Mergeability Score: 🟡 Moderate · up to ced7b

The API documentation still assigns the wrong return type to one revision-aware client method, which could mislead users implementing against the client API; merge should wait for this bounded documentation error to be corrected.

Poem

I hop through docs with ears held high,
New registry names now touch the sky.
CLI paths and cache notes align,
Config trails follow a clearer line.

| `request_model_on_server(name, provider)` | Request a download on the server at the provider's default revision |
| `request_model_on_server_revision(name, provider, revision)` | Same, pinned to a branch, tag, or commit SHA; returns the resolved revision |
| `request_model(name, provider)` | Request a model using the server as source of truth, streaming files locally when shared storage is disabled |
| `request_model_revision(name, provider, revision)` | Same, pinned to a revision; returns the snapshot path and the revision it resolved to |
| `request_model_with_smart_fallback(name, provider, ...)` | Request via the server, falling back to a direct provider download when the connection cannot be established |
| `request_model_with_smart_fallback_revision(name, provider, revision, ...)` | Same, with the direct-download fallback honouring the same pinned revision |

The `_revision` variants take an optional branch, tag, or commit SHA and return a `ModelDownloadResult { path, resolved_revision }`. The non-`_revision` methods delegate to them with no revision pinned.

Document the revision-aware return types separately.

request_model_on_server_revision returns CommonResult<Option<String>>. request_model_revision and request_model_with_smart_fallback_revision return CommonResult<ModelDownloadResult>. Update the summary so it does not apply ModelDownloadResult to every _revision method.
