In @.github/workflows/test.yml:
- Line 16: Update the actions/checkout step in the workflow to set
persist-credentials to false, ensuring pull-request verification does not retain
Git credentials while preserving the existing checkout behavior.
In `@src/caprover.ts`:
- Around line 122-126: Update the request timeout handling around
request.setTimeout in deploy to enforce a five-minute wall-clock deadline with
an independent timer, rather than relying on socket inactivity. Destroy the
request with the existing timeout error when the deadline expires, and clear the
timer when the request closes.
- Line 58: Update the deployment transport selection around the url.protocol
check so remote CapRover deployments require HTTPS, while HTTP remains available
only for explicitly trusted local or restricted-network targets. Preserve the
existing x-captain-app-token and deployment behavior for permitted connections,
and reject or block untrusted remote HTTP URLs before sending requests.
In `@tests/deploy.test.ts`:
- Line 94: Update the tests that set process.env.GITHUB_WORKSPACE to use
vi.stubEnv instead of direct mutation, and call vi.unstubAllEnvs in afterEach
cleanup so the original environment value is restored even when a test fails.

83-83: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick winLimit the buffered CapRover response size.
The client stores every response chunk without a limit. A faulty CapRover endpoint can continuously send data, reset the inactivity timeout, and consume runner memory until the action hangs or terminates.
Track the accumulated byte count. Reject and destroy the response when it exceeds a small API-response limit. This limit does not impose a wall-clock deadline on healthy archive uploads.
Proposed response limit

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Restore image precedence when both deployment inputs are set.
When a workflow supplies both inputs, this validation fails the action instead of deploying image. Keep image as the selected mode and ignore tar-file in this case.
src/inputs.ts#L44-L46: remove the mutual-exclusion error and preserveimageas the selected deployment mode.tests/inputs.test.ts#L53-L63: replace the rejection test with an assertion thatimagetakes precedence.README.md#L89-L89: document thatimagetakes precedence overtar-file.
As per PR objectives: image precedence when both inputs are provided.

Summary
Replaces the Docker action and globally installed CapRover CLI with a bundled Node 24 action that calls the small subset of the CapRover API used for deployments.
Behavior preserved
imagedeploys the requested imagebrancharchives and deploys that Git ref./deploy.tarimageandbranchare supplied,imageretains the current precedenceArchitecture
src/dist/index.jsbundle/api/v2Tests
16 tests cover required inputs, input trimming, all existing deployment modes, image precedence, Git archiving, special-character paths, multipart uploads, app-token headers, trailing server slashes, API errors, missing tar files, temporary archive cleanup, and interrupted responses.
Manual verification
Ran the committed
dist/index.jsas an action process against a local CapRover-compatible HTTP server. Verified action input handling, multipart upload,/api/v2endpoint construction, authentication headers, and the accepted deployment response.This PR intentionally keeps the v1 input contract. The simplified v2 UX follows in a stacked PR.
