HUX-04/HUX-08: after a successful tool execution the hux-runtime plugin now registers freshly written files as typed artifacts (create or immutable version by conversation-scoped title, bounded to 1 MiB, deterministic idempotency keys) and records up to three deduplicated web sources from real network/web_search output. Emitters are fail-open and can never break the tool result. Delivered through the plugin ConfigMap; 95% branch coverage; quality contract updated.

HUX runtime integration
This plugin wraps Hermes's real tool_execution middleware boundary. It is
inert unless HUX_RUNTIME_ENABLED=1; HUX_TOOL_ENFORCEMENT=1 additionally
requires every exact tool call to be released by HUX before next_call runs.
The process needs these read-only files:
HUX_SUBJECT_FILE: router-publishedusr_<64 lowercase hex>binding;HUX_WORKER_KEY_FILE: mode0400, used only for worker-trust loopback calls;HUX_CONTEXT_KEY_FILE: the WebUI-created, owner-only, single-link 32-byte context key. Chat and the runtime use the samehux.context.id.v1helper.
Set HUX_TENANT_SLOT=slot-N, HUX_BASE_URL=http://127.0.0.1:8790, and a
bounded HUX_TIMEOUT_SECONDS (default 3). The HUX service and plugin must be
in the same pod. HUX_PROJECT_SOURCE defaults to profile:default and must
match the source used by WebUI context creation. No HUX port belongs in a
Service or ingress.
Every turn first calls the worker-trust, idempotent
POST /hux/v1/context/bootstrap. The sidecar must verify every supplied ID
against the same context key before registering the deterministic project,
session, and conversation. Deployment remains default-off until that route is
present in the converged backend.
Hermes currently exposes interruption through on_session_end(interrupted=True)
but does not give plugins the authoritative process-registry state or reverted
side-effect list required by hux_hook.on_stop. The plugin therefore records a
failed/interrupted run and never claims cancellation. A real bridge requires a
new post-interrupt hook fired only after the runtime has killed and reaped every
registered tool process, with run_id, session_id, turn_id,
process_registry_empty, and redacted side-effect receipts.
Quality registration must include services/hermes/plugins/hux-runtime/*.py
as source and testing/tests/test_hermes_hux_runtime_plugin.py as its focused
test. The current focused gate is 54 passing tests with every production file
above 95% line and branch coverage.
Post-tool emitters (HUX-04 / HUX-08)
emitters.sync_after_tool runs only after a successful tool execution and
never raises into the tool path. A successful write_files tool whose
arguments name a real, non-symlink file of at most 1 MiB creates (or, when a
same-titled artifact already exists in the conversation, appends an immutable
version to) a typed artifact through the loopback API; the service's secret
scrubbing and restricted forcing still apply. A successful network or
web_search tool records up to three deduplicated web sources found in the
first 64 KiB of real tool output. Both use deterministic idempotency keys, so
retries never duplicate records.
