Subprocesses spawned by the terminal tool, execute_code, Docker backend, and the codex app-server could inherit Hermes-internal secrets that the name-based `_HERMES_PROVIDER_ENV_BLOCKLIST` can't enumerate, because they're injected into `os.environ` at runtime under dynamic names: - `AUXILIARY_<TASK>_API_KEY` / `AUXILIARY_<TASK>_BASE_URL` — per-task side-LLM credentials bridged from `config.yaml[auxiliary]` by gateway/run.py and cli.py (vision, web_extract, approval, compression, plugin-registered tasks). Often separate, higher-spend keys plus base URLs pointing at private endpoints. - `GATEWAY_RELAY_*_SECRET` / `_KEY` / `_TOKEN` — relay-auth material provisioned by gateway/relay. Additionally, agent/transports/codex_app_server.py built its spawn env from a raw `os.environ.copy()`, bypassing the centralized `hermes_subprocess_env()` helper entirely — handing every codex subprocess the full Tier-1 secret set (GH_TOKEN, gateway bot tokens, Modal/Daytona infra tokens, dashboard session token) unfiltered. This is the #29157 sibling spawn-site gap; copilot_acp_client already routes through the helper. Fix — single chokepoint: - Add `_is_hermes_internal_secret(key)` in tools/environments/local.py as the single source of truth for the dynamic secret patterns. Matches AUXILIARY_*_API_KEY / _BASE_URL and GATEWAY_RELAY_*_SECRET/_KEY/_TOKEN; leaves non-secret AUXILIARY_*_PROVIDER/_MODEL and GATEWAY_RELAY routing hints visible. - Wire the predicate into every spawn path unconditionally (ignores skill env_passthrough opt-in AND inherit_credentials — a model-driving CLI never needs these): `_sanitize_subprocess_env` (both loops), `_make_run_env` (foreground), `hermes_subprocess_env` (Tier-1), and the Docker forward filter. - Add the static GATEWAY_RELAY_* names to `_HERMES_PROVIDER_ENV_BLOCKLIST` so the exact-match path catches them independently of the predicate. - Add the GATEWAY_RELAY_ID/_SECRET/_DELIVERY_KEY triplet to `_ALWAYS_STRIP_KEYS` (Tier-1) so it is stripped unconditionally on EVERY spawn surface — including the codex/copilot `inherit_credentials=True` path that skips the Tier-2 blocklist. `_SECRET`/`_DELIVERY_KEY` are already predicate-matched; `_ID` has no secret suffix, so enumerating it here is what closes its leak on the inherit path (self-review W1). - Defense in depth: env_passthrough.py `_is_hermes_provider_credential()` now consults the same predicate, so a skill can't register these names as passthrough and tunnel them into an execute_code / terminal child. - Route codex_app_server through `hermes_subprocess_env(inherit_credentials=True)` — strips Tier-1 + dynamic-internal secrets while provider creds (which codex needs to authenticate) still flow. Consolidates PRs #53715 (necoweb3 — the _is_hermes_internal_secret backbone + Docker filter), #53503 (srojk34 — env_passthrough guard), and #55709 (srojk34 — codex routing). Retires #52348 (claudlos): its copilot half is already on main, and its codex half used the full-strip `_sanitize_subprocess_env` which would break codex provider auth — the correct tier is `inherit_credentials=True`. Tests: TestHermesInternalDynamicSecrets (terminal + predicate + passthrough override), TestInternalDynamicSecrets (hermes_subprocess_env both tiers), TestSpawnEnvSecretStripping (codex spawn env), plus env_passthrough defense-in-depth cases.
