Reworks the salvaged command module into a CommandSource(SecretSource) registered as the third bundled source, composing with Bitwarden and 1Password through the apply_all() orchestrator — enable any combination simultaneously. The original PR's secrets.provider single-selector is deliberately dropped: multi-source is first-class and a mutually exclusive provider switch would regress that. - fetch() only fetches; precedence/override/conflicts/environ writes stay in the orchestrator. ErrorKind classification + remediation hints. - apply_command_secrets() kept as a legacy shim (parser/security helpers unchanged: HERMES_SECRET_KEY data-only key passing, cross-key misroute guard, base64-padding disambiguation, timeout + output cap, structured- fields-only failure logging, stderr discarded). - Dispatch tests rewritten for the registry path incl. an explicit two-sources-compose test; selector tests removed with the selector. - cli-config.yaml.example + docs page (command.md), secrets index entry. - contributors mapping for mvalentin@valensys.net -> 0xr00tf3rr3t.

"""E2E tests for the ``command`` secret source.
|
|
|
|
These exercise the REAL resolution path: real helper shell scripts written
|
|
to a temp dir (chmod +x), real ``/bin/sh -c`` subprocesses, and a real temp
|
|
HERMES_HOME with a config.yaml routing ``secrets.provider: command`` through
|
|
``hermes_cli.env_loader._apply_external_secret_sources``.
|
|
|
|
Security invariants under test (ported from the desktop TS provider):
|
|
|
|
* the requested key travels ONLY via the ``HERMES_SECRET_KEY`` env var —
|
|
never interpolated into the shell string (hostile key names are inert);
|
|
* cross-key misroute guard: a single env-shaped line for a DIFFERENT key
|
|
never leaks as the wanted key's value;
|
|
* base64 '=' padding is not misclassified as a dotenv line;
|
|
* hard timeout + degrade-to-empty on every failure mode, never raise;
|
|
* failure logging carries structured fields only — never the command
|
|
string or any secret value.
|
|
|
|
NOTE: tests assert on key NAMES, lengths, and presence — never log secret
|
|
values themselves.
