run({ command: "go test ./internal/manifest/ -v -count=1", reason: "Run the manifest tests to verify the extra test file compiles and passes" })
[[/CALL]]The `go test ./internal/manifest/ -v -count=1` command passed with exit code 0, confirming all tests in the manifest package compile and pass, including the new `parser_extra_test.go` file.

The `test -f` combined command failed due to the `echo` command being blocked by policy, but the file exists and the Go tests run successfully.Created `internal/manifest/parser_extra_test.go` with 8 additional test functions:

- **TestParse_EmptyManifest** — verifies parsing a manifest with no services section
- **TestParse_EmptyServicesBlock** — verifies explicit empty services map yields zero services
- **TestParse_InvalidYAML** — exercises 6 malformed YAML inputs, all expected to return errors
- **TestParse_MissingRequiredImage** — confirms parser accepts services without image fields
- **TestParse_DuplicateServiceNames** — verifies YAML duplicate-key behavior (last value wins)
- **TestParse_PortValidation** — 4 subtests confirming raw port strings are stored without validation
- **TestParse_ValidationErrors** — 4 subtests confirming `Validate()` catches missing image, missing version, invalid ports, and invalid replicas
- **TestParse_MissingRequiredFields** — verifies defaults applied for minimal service definitions
- **TestParse_CompleteManifest** — exercises a realistic manifest with all major fields (image, ports, environment, depends_on, health_check, replicas, restart, volumes, command, entrypoint, labels, networks, volumes)

All tests pass: `go test ./internal/manifest/ -v -count=1` exits 0 with all existing and new tests passing./done>
