fix(observer): project each run into its channel and scope the link to it - #570
khaliqgant wants to merge 3 commits into
Conversation
…o it
The observer link a run printed opened an arbitrary workspace channel with
nothing about the flow: no run published anything to Relaycast (only agent
chat was projected), and the link was minted workspace-wide after the run
had already finished.
- kernel: run.start {watch: true} streams the new run's entries on the
starting connection from run.spawned on, registered before the first
append so each entry arrives exactly once. The only way to observe a run
whose id the caller does not know yet.
- sdk: a run projection publishes run start, every step transition and the
terminal outcome into wf-<runId>, each message carrying the run snapshot
under metadata.relayflow. YAML runs fold the journal stream; authored runs
use the executor's progress events. Resume replays history silently.
- cli: the observer token is scoped to the run's channel and printed on
stderr as soon as the run exists, then again after RUN as before.
- Fail open throughout: a projection or mint failure is one [observer]
line; a daemon that predates watch is started again without it.
- tests: isolate the agent-relay workspace store so no test publishes into
a developer's real workspace.

Suggested reviewers: Merge Risk: 🟡 Moderate · up to Runs are unaffected. For YAML flows with LLM or agent steps, however, the observer dashboard stops receiving step updates after the first out-of-band step and then jumps straight to the final status. That undermines the main purpose of this change. Keep the journal listener attached until the run finishes before merging. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

- Around line 213-222: Keep the journal entry listener registered through
outcome classification so entries emitted while parked workers resume are
captured. Update startWatched so it does not remove the listener when runStart
returns; in executeCheckedFlow and resumeFlow, register it before starting or
resuming and remove it only after classifyOutcome completes, including on

Summary by cubic
Fixes the observer link
flows runprinted, which opened an arbitrary workspace channel with nothing about the flow: the token was workspace-wide, nothing projected the run, and the link only appeared after the run finished. Now each run projects its lifecycle into itswf-<runId>channel and the link is scoped to that channel, printed on stderr as soon as the run exists.run.start {watch: true}streams the new run's entries on the starting connection fromrun.spawned, registered before the first append so there is nothing to replay. This is the only way to observe a run whose id the caller does not yet know.wf-<runId>, each message carrying the run snapshot undermetadata.relayflow(v1). YAML runs fold the journal stream (epoch summaries reset step state); authored runs use the executor's progress events plus a newonRunStartedhook. Publication goes through a per-session publisher agent, retired history-preserving after its queue drains — including when the create response was lost.RUNas before.[observer]line and never touches the run. A daemon that predateswatchrefuses the field while decoding, before any run exists, so the CLI starts again without it and prints that the run was not projected. A refusedrun.watchon resume is ignored.tests/isolate-workspace.tspointsAGENT_RELAY_HOMEat an empty dir and clearsRELAYCAST_WORKSPACE_KEY, so SDK tests never mint real tokens or publish into a developer's real workspace.docs/OBSERVER-RUN-PROJECTION.mdrecords the design and its fail-open boundaries.Written for commit 63c71cc. Summary will update on new commits.
