Retired payload key environment name is empty

Error message

Retired payload key environment name is empty

What it means

This error is thrown during payload key-set loading when a retired environment name (a payload-key environment being retired) is blank or whitespace-only. The loader validates each entry in `retired_envs` before deriving/loading its key, refusing empty names because they would produce ambiguous or unusable key identifiers. It guards configuration integrity of the sealing key set.

Solutions

1. Inspect the retired-environment configuration source and remove any empty or whitespace-only entries
2. Trim and filter the list at the call site before passing `retired_envs` to `load`
3. Fix any splitting/parsing code that emits empty segments (e.g. split on ',' without filtering blanks)

Example fix

// before
let retired_envs = raw.split(',').collect();
// after
let retired_envs: Vec<_> = raw.split(',').map(str::trim).filter(|s| !s.is_empty()).collect();

let retired: Vec<&str> = retired_envs.iter().map(|s| s.trim()).filter(|s| !s.is_empty()).collect();
anyhow::ensure!(!retired.is_empty() || retired_envs.is_empty(), "retired envs contain blank names");

fn is_valid_env_name(s: &str) -> bool { !s.trim().is_empty() }

When it happens

Trigger: Calling `load` with a `retired_envs` list that contains an empty string or a whitespace-only entry, typically from a misparsed or mis-edited configuration list.

Common situations: Hand-edited config files with a trailing comma (`env1,,env2`), YAML/TOML lists containing an empty element, or environment-variable parsing that splits on separators and yields empty segments.
