Core no longer assembles a whole trace locally. Every workflow node is uploaded
the moment it completes as its own `execution_node` record, and each execution
closes with exactly one `execution_chain` record; all records of one execution
carry the same `event_id`, so Space groups them back into a single chain.
- every execution starts at an inbound event: event-less Pipeline lanes and
WebUI/API debug runs synthesize their virtual inbound event at the boundary
and are marked debug=true, so a Runner is never a trace origin
- sampling is decided once per event from a stable hash of the event id (the
previous `int(id[:8], 16)` raised on every `platform:`-prefixed id and so
dropped every successful inbound-event chain) and is reported on each record
as sample{mode,denominator}; the default mode is now `all`
- the local trace buffer, the 120s TTL, the per-process trace cap and the shared
open-node mirror are gone, which also removes the truncated-chain upload and
the re-buffered-closed-trace leak they caused
- a broken chain is always uploaded, and its reason falls back to the first
failed node so the chain explains itself
- flush keeps records until the sender accepts them and counts what it drops;
telemetry health replaces the unused send-task queue
- heartbeat reports bound Agent / plugin-processor / event-binding counts
- bound Pipeline and Agent resources (plugins, MCP servers, knowledge bases,
tools with their Host source, skills, models and the Runner schema selectors
that picked them) are reported on the chain record
- failure text is bounded and redacted instead of passing exception text through
- the dead per-query feature counters and their call sites are removed
Wire contract: schema 2 (`execution_node` / `execution_chain`).
Multi-Workspace deployments fail the public plugin icon route closed (404), so plain <img src> icons broke everywhere locally and for the runner picker in production. A shared cached hook fetches the authenticated icon for installed plugins and leaves marketplace surfaces on the cloud URL.
The SDK binds one transfer root inode (mode 0700) and picks it per profile: a shared worker uses /tmp/lbp-rpc while a host without the profile env fell back to data/temp/lbp, so plugin icons and assets died with 'Invalid file transfer capability'. The host now pins the shared root, and a plugin absent from the resolved Workspace answers 404 instead of 500.
The connector stored only uuid/code/message, so the ops reporter stamped every entry with its own sampling time and a stale failure looked freshly broken on each report. Failures now carry failed_at and the payload publishes it.
The execution trace rewrite batches records and uploads them from
ExecutionCounters.flush(), replaced the per-trace direct send, dropped the
window counters, made the execution id the record identity and records the
inbound event stage after the routing stage. The ingress tests still asserted
the old mechanism, so they failed on every Python version.
Assert what the pipeline now emits instead: flush the buffered records and read
them back, require the trace registry to be empty afterwards, assert the
deterministic execution id, expect the route stage before the inbound stage,
and give the dispatch stubs the execution_id parameter the ingress passes.
The shared Cloud deployment runs one Plugin Runtime for every Workspace, but
nothing reported its health: the instance only exposed two aggregate numbers on
its own health probe, and the per-installation failure registry, the desired
state registry and the reconcile outcome lived in memory with no reader.
Add RuntimeOpsReporter, which every 30 seconds reads the Runtime ``/healthz``
probe over HTTP (derived from ``plugin.runtime_ws_url``), merges it with the
connector's desired-state, failure and reconcile summaries, and posts one
sample to the Space control plane on the existing authenticated direction.
Delivery is best-effort and bounded: a single in-flight request, a ten second
timeout, dropped samples counted in ``runtime_ops`` on the instance health
probe, and a failed probe recorded as a drop so the dashboard shows staleness
instead of grading a stale sample as healthy.
Cloud-only: a non-cloud deployment never enables the reporter, and the channel
is independent of product telemetry so ``space.disable_telemetry`` cannot blind
the ops dashboard.
