Contract file errors: load

Codes that start with seampact/load/ come from reading your YAML files. They print as api.yaml:5:13: error seampact/load/yaml-boolean: ...: file, line, column, code.

Code	Cause and fix
seampact/load/yaml-syntax	The YAML cannot be parsed. Fix it at that position: look for a missing ], } or quote, or a wrong indent.
seampact/load/workspace-shape	The file must start with api: or workspace:. Often a YAML syntax error is the real cause: fix the yaml-syntax line first.
seampact/load/yaml-boolean	A plain off, no or yes is a boolean in YAML 1.1. Quote it: 'off'.
seampact/load/yaml-ambiguous-scalar	A value such as 1_00 reads as a number or a string depending on the parser. Quote it.
seampact/load/yaml-number-format	The number is not plain decimal. Write it in plain decimal, or quote it.
seampact/load/scalar-type	The value has the wrong type, for example a number where a mapping goes. Write what the message names.
seampact/load/duplicate-key	A key appears twice in one mapping. Remove one: the message points at the first.
seampact/load/file-missing	A $include or $ref file does not exist. Create it or fix the path.
seampact/load/include-cycle	Files include each other. Break the loop.
seampact/load/path-escape	A path leaves the workspace. Move the file inside, or put a workspace.yaml above every file the contract reads.
seampact/load/pack-not-found	A pack name matches no installed package or file. Install the pack package, or write the pack as a path: ./packs/name.yaml.
seampact/load/declaration-twice	Two layers declare the same name, even when the copies are identical. Remove one copy.
seampact/load/name-not-visible	A shared file or base uses a name only an api declares. Move the declaration into the shared file or the base.
