Root AGENTS.md § Code Shape Rules replaces "module-level constants are fine — they cache after
_apply_profile_override() sets HERMES_HOME" (true for `hermes -p x <cmd>`, inverted under the
multiplex gateway and the Desktop/dashboard `serve` backend, where os.environ holds the LAUNCH
profile) with the invariant: a profile = home + secret scope + terminal scope, bound per profile
ACTIVITY, and every execution point with no turn on the stack binds it explicitly. Names the real
seams: gateway/run.py::_profile_runtime_scope, tui_gateway @_profile_scoped +
_session_profile_runtime_scope (+ _profile_runtime_scope_tokens, launch_profile_policy ->
set_multiplex_active), cron/scheduler_provider.py::_profile_cron_scope,
gateway/run_agent_cache.py::_run_release_in_profile_scope, tools/environments/local.py::
served_profile_child_env, agent/memory_provider.py::spawn_context_thread. Adds a routing-table row
for profiles / multiplex / secret scope.
Area AGENTS.md paragraphs, one per seam, for gateway/ (activity-not-turn binding, hooks per
profile, adapter YAML never reaches os.environ, unserved shared-ingress reported via
_note_unserved_secondary_platform + needs_attention at the single writer), tui_gateway/ (RPC
binding is home AND secret AND terminal; HOME-only is half-bound; teardown chokepoint), cron/
(per-home tick lock, ticker scope incl. pre-loop code, kanban notifier routing, worker liveness by
(pid, worker_started_at) fingerprint, descendant fence as a path), hermes_cli/ (DEFAULT_CONFIG
key <-> reader parity, service-install matrix, -p vs multiplex home binding), tools/ (check_fn
reads through get_secret and is cached per hermes_home_key, one env builder per spawn, MCP trust
per profile), plugins/ (lifecycle hooks are bound by the caller; never cache the home from
initialize()), apps/desktop/src/ (pooled serve per (connection, profile); remote topologies),
agent/ (end-of-session flush is caller-bound; set_multiplex_active gates fail-closed).
Corrects the statements the multiplex model made wrong, in the same PR: root module-constant
sentence; hermes_cli "sets HERMES_HOME before any import" (+ cli-internals.md);
ADDING_A_PLATFORM.md §2 raw os.getenv loader (now an _ENV_STEPS row through config.py::_getenv)
and §4 platform_env_map in gateway/run.py (now _PLATFORM_ALLOWLIST_ENV in pairing.py + registry
allowed_users_env); platform_registry.py "may set os.environ (guard with not os.getenv)";
cron/AGENTS.md hardcoded ~/.hermes/cron/.tick.lock; gateway-internals.md agent:main as THE key
format, ~/.hermes/hooks/, single-profile `gateway stop`, plus a new "Multiplexed profiles"
section; tools/AGENTS.md os.getenv check_fn sample; "installed per turn" wording; "one temp
HERMES_HOME" E2E wording; multi-profile-gateways.md intro lists system units, Windows tasks, s6
and the Desktop backend.
