Rebuilt against the post-refactor owners: the chat-completions route now
lives in gateway/platforms/api_server_openai_routes.py, the wake gate in
tools/delegate_tool_dispatch.py, and session_context.py was reshaped —
the original patch aimed at code main no longer has.
Header-less OpenAI-compatible clients get a fingerprint-derived session
id bound as the api_server chat_id. delegate_task's background gate
treated ANY bound session id as wake-capable and dispatched detached
subagents, but for derived ids the wake self-post lands in a session
whose history the client never reloads — the result is undeliverable by
construction.
Bind a wake_capable provenance flag at session-bind time, DEFAULT-DENY
at the central boundary (set_session_vars and _bind_api_server_session
both treat an omitted declaration as denied; a binder that says nothing
grants no wake authority): "1" only from audited producers whose client
can address the id again (explicit X-Hermes-Session-Id — 403-gated on
API_SERVER_KEY — native /api/sessions/{id} routes, /v1/runs); "" for
fingerprint-derived ids. The delegate gate requires the flag (fail-closed,
captured pre-child-construction alongside origin_wake_sid) and keeps the
forced-sync fallback with its honest note.
