ward#1013
What to build
When a director surface cannot reach the host dispatch broker, ward should fail with one actionable diagnostic instead of a loaded live-repair problem. This issue does not require proving the current host broker is healthy.
Acceptance criteria
warded psor the ward-native equivalent reports broker-unavailable errors with the broker address source, connection failure, and one next remediation step.WARD_DISPATCH_BROKER_ADDRconnection.Non-goals
Decision for headless carry
Kai confirmed ward#1013 is too loaded and likely to make an engineer miss the goal. This child carries one deliverable: actionable diagnostics for director broker-unavailable failures.
P1 clarity note from Kai on 2026-07-15: an advisor pre-flight research step should handle the exact remediation wording and diagnostic taxonomy before implementation. The engineer should not invent a live-repair flow. The deliverable remains actionable broker-unavailable diagnostics, with advisor research used to pin the message shape.
WARD-TRIAGE: warded control plane coherence milestone
This issue is part of the
warded control plane coherencesprint. The release thesis is to makewardedfeel like one dependable control plane for agent work: higher safe parallelism, coherent config defaults, reliable broker/container behavior, human-feedback gates, and enough structured evidence for the next actor after a paused or failed run.For this sprint,
headlessmeans an engineer should be able to carry the issue from current issue context to a merged change without new human decisions. If the issue discovers a missing decision, split or demote the unclear part instead of guessing.WARD-TRIAGE: coherence-core label
This issue is part of the
coherence-corereview set for thewarded control plane coherencesprint. Treat it as release-spine work: it should directly improve the safety, capacity, configuration coherence, observability, or recovery loop that makes director burndown trustworthy.Core does not mean broader scope. Keep the implementation narrow, verify current
mainbefore reusing prior failed PRs, and split any design fork or lower-confidence follow-up out of the core path.WARD-DIRECTOR: demoted from headless
This issue is not immediately dispatchable in the headless lane because the latest clarity note requires advisor pre-flight research to settle the remediation wording and diagnostic taxonomy. The
headlesslabel has been removed while the issue remainscoherence-core. Re-enter the headless lane after that research leaves a self-contained implementation contract.🔎 ward agent advisor
ward agent advisor --harness codexran a one-shot standard research pass on this question:Advisory recommendation
Keep this issue as a narrow same-repo implementation in
coilyco-flight-deck/ward. The right fix is a small typed dispatch-broker diagnostic layer, not a host repair flow and not a capacity-system rewrite.Current behavior to change
The current read-only broker paths already have most of the plumbing, but unreachable broker handling is too fail-open:
maybeForwardAgentDispatchToHostBrokerreturns(false, nil)whenWARD_DISPATCH_BROKER_ADDRis set buthostDispatchBrokerReachablefails, so ref-mode engineer/advisor/QA dispatch can fall through to the local launch path.forwardFreeformEngineerLaunchToHostBrokerhas the same fallback after the freeform issue is filed.prWorkflowForwardedalso skips the broker on unreachable address and falls back to the direct PR workflow path.ward agent list/ aliaspsandward agent logsswallowerrDispatchBrokerUnavailableand fall back to local host reads, which hides the surface problem.TestForwardAgentDispatchToHostBrokerSkipsUnreachableBrokerandTestPRWorkflowForwardedSkipsUnreachableBrokerpin the behavior this issue wants to retire.Recommended taxonomy
Use three explicit operator-facing states:
broker-unreachable:WARD_DISPATCH_BROKER_ADDRis present, but TCP connect fails immediately, such as connection refused, no route, DNS/host failure, or wrong gateway address.broker-timeout: dialing or waiting for the broker response exceeds the bounded timeout/context. This is different from refusal because the address may exist but the broker or gateway is wedged.capacity-defer: the broker is reachable and host ward answered, but the host-side launch refused because the engineer pool is full. This should stay backpressure, not broker failure.Suggested output shape for broker contact failures:
For a dial deadline:
For capacity:
The remediation should deliberately stop there. Do not tell a sealed engineer to restart or debug the live host broker. The PR body should explicitly say live host-broker health was not verified from the sealed engineer container.
Implementation contract
Recommended option: add a typed helper rather than scattering string-only errors.
hostDispatchBrokerReachable(ctx, addr) boolwith a richer probe/result, for exampleprobeHostDispatchBroker(ctx, addr) dispatchBrokerDiagnosticor(ok bool, diag *dispatchBrokerDiagnostic).kind,addrSource(WARD_DISPATCH_BROKER_ADDR),addr, original connection error text, and one remediation string.errDispatchBrokerUnavailableas the sentinel if useful, but attach kind/source/detail in a structured type so callers can render consistent text and tests can assert classification without brittle full-string matching.WARD_DISPATCH_BROKER_ADDRis set andWARD_READONLY=1, brokered dispatch should be mandatory. If probing or sending fails with broker-unavailable/timeout, return a handled error and do not fall through to local launch.warded psshould be satisfied by the existingward agent list/psalias.

Live verification note for the PR
The PR body should say something like:
Live host broker health was not verified from the sealed engineer container; verification was limited to unit fixtures for refused/timeout broker addresses and existing broker response tests. A real host-surface check requires an observable director session on the host.Researched and posted automatically by
ward agent advisor --harness codex(ward#179). This is one-shot research, not a carried change - verify before acting on it.— Codex, via

The engineer seeded the body once at launch and never re-reads it, so a comment or edit reaches only human readers, never the running engineer. A correction goes to a new issue, dispatched fresh. That is the only channel that reaches a run in flight. Where the forge supports it, ward locks this conversation to make that a road-block rather than a convention (ward#494).

details
workflow: pull-request-and-merge; review summary: skipped (review gate intentionally skipped because temporary ward default pending brokered QA)
felt: steady but broad enough to touch the dispatch gate, read surfaces, and diagnostics together; the only surprise was the lint pass forcing the diagnostic kind switch and a flatter list path.
confidence: high
surprises: Forgejo's merge API returned a blank JSON stub even though the PR merged cleanly.
follow-ups: none unless you want the same broker diagnostic wording mirrored in other read-only surfaces.
