Inline comments:
In `@docs/control-management.md`:
- Line 50: Update the Mental model architecture map to account for the
deployment semantics introduced by plugin.deploy.v1, including artifact storage,
leases, and durable history. Add a distinct Deployment lane or explicitly assign
these responsibilities to an existing lane, while preserving the documented
behavior that deployment stages the JAR for the next restart without hot
reloading or restarting.
In `@README.md`:
- Around line 212-215: Update the README’s request-size documentation to state
that the 4 MiB limit applies to generic JSON requests, while POST
/api/v1/artifacts/votingplugin accepts artifacts up to 64 MiB. Ensure the
management guide’s corresponding HTTP request-limit statement uses the same
route-specific exception.
In `@src/main/java/com/bencodez/votingplugin/control/http/ControlHttpServer.java`:
- Around line 953-954: Update sendArtifact so the input stream opened by
artifactStore.open is enclosed by try-with-resources before sendResponseHeaders
is called, ensuring it closes when response setup throws; preserve the existing
response streaming behavior after headers are sent.
In
`@src/main/java/com/bencodez/votingplugin/control/protocol/DeploymentRequest.java`:
- Around line 31-34: Move the List.copyOf(nodeIds) call in the DeploymentRequest
validation flow to after the loop that checks null, format, and uniqueness, so
null elements produce IllegalArgumentException and are mapped as validation
errors. Preserve the existing validated-copy behavior after the loop.
In `@src/main/resources/web/app.js`:
- Around line 5427-5438: Update the batch submission loop around authorized and
submittedOperations so a NODE_UNAVAILABLE rejection from an individual batch
records that batch’s node IDs and continues to later batches. Preserve fail-fast
behavior for authentication changes, artifact-metadata errors, and
operation-limit failures, and ensure the final deployment status identifies
nodes skipped due to the rejected batch.

🟠 Major · Retry batches after eligibility changes. · src/main/resources/web/app.js:5395-5487
5395-5487: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick winRetry batches after eligibility changes. The batch size is valid, but
deploymentTargets()snapshots eligibility before the upload. If one node becomes unavailable beforeDeploymentOperations.createvalidates the batch, the server rejects the entire batch withNODE_UNAVAILABLE. The catch block then marks every node in that batch as unavailable and skips them, so still-eligible nodes can be omitted. Refresh eligibility and retry or split the rejected batch instead of discarding the entire batch.🤖 Prompt for AI Agents
