The code registry cannot tell a plugin-only name from one the gateway
reads straight off os.environ (TELEGRAM_GROUP_ALLOWED_USERS), so the
note was false for real settings. Every UPPER_SNAKE name simply lands
in .env; the docs say so.
Production code must not depend on website/docs being present; the
"Hermes does not read this name" note now keys only on the code
registry (OPTIONAL_ENV_VARS / _EXTRA_ENV_KEYS / setup-hidden suffixes).
`hermes config set TELEGRAM_GROUP_ALLOWED_USERS ...` (and ~290 other documented
variables Hermes reads straight from os.getenv without registering them in
OPTIONAL_ENV_VARS) still landed as a config.yaml top-level scalar with a notice,
while the setup flows write .env and one-shot CLI readers never bridge YAML
scalars — two writers, two readers. #112250 routed the registered names; this
closes the class with a shape rule: any bare ^[A-Z][A-Z0-9_]*$ key is an
environment setting.
- set: writes .env, drops a stale config.yaml copy, never writes UPPER_SNAKE
into config.yaml (--force included); the env writer's denylist
(HERMES_YOLO_MODE, PATH, ...) now refuses cleanly instead of the YAML detour
bridging the value into os.environ; a name neither registered nor in the
environment-variables reference gets a one-line note but is still saved.
- get: .env first; a leftover top-level config.yaml copy is reported as stale.
- unset: removes the .env entry and the stale copy.
- Registered names, credentials (credential lifecycle + masking), dotted paths
and lowercase bare keys are unchanged.
Fixes#111848 (first half landed in #112250).
`hermes config set FEISHU_HOME_CHANNEL oc_x` wrote the top level of config.yaml
while the platform setup flows and /sethome write the same name to .env via
save_env_value, so two writers fed two readers: the gateway bridges the yaml copy
into the environment only when .env lacks the name, one-shot CLI readers never
bridge, and the two copies diverged silently (#111848). Only credential-shaped
names were routed to .env because `_is_env_config_key` is the provider-credential
predicate.
Follow-up to KoNit-K's cherry-picked fix (#111850), which routed the
`setup_hidden_env` suffix family: the predicate now lives in the topical sibling
`hermes_cli/config_env_routing.py` and covers every bare name Hermes itself
registers as an environment variable (OPTIONAL_ENV_VARS, _EXTRA_ENV_KEYS — "env
var names written to .env" — plus the setup-hidden suffixes for plugin adapters
nobody enumerated), so `*_ALLOWED_USERS`, `WHATSAPP_MODE`, `MATRIX_PASSWORD` and
the rest of the adapter-saved family take the same file. `set` and `unset` also
drop a stale same-named top-level config.yaml copy so the reporter's drift cannot
come back, and `get` resolves .env first then that copy — the gateway's own read
order. Provider credentials keep the credential_lifecycle rotation path.
