Bug

When an engineer container is reaped, any flushed/preserved log location is not printed into the container log stream. This makes postmortems harder when the operator is viewing the run through docker logs: the container may say it is reaping, but not where the durable logs were written.

Context

During the 2026-07-08 harness outage/debugging run, Claude, Codex, OpenCode, and Goose engineer lanes each failed before useful work. The operator was viewing failure output through Docker. For reaped runs, it was unclear whether logs were flushed eagerly and, if so, where the flush landed because the reaper did not print the destination into the logs being viewed.

Concrete recent run to inspect: coilyco-flight-deck/ward#692 (engineer-goose-ward-692) was reaped after a Goose engineer failure.

Expected behavior

Whenever ward reaps an engineer and flushes, preserves, archives, or otherwise writes logs to a durable host path, the reaper should print that path into the container log stream before exit.

If no durable log flush is available, the reaper should say that explicitly.

Do

  • Inspect the reaper log-flush path for engineer containers.
  • Make the reaper emit the final log destination into the container-visible output.
  • Include both successful flush and no-flush cases.
  • Keep paths useful to the host operator, not only paths inside the container namespace.
  • Add coverage for the reaper output contract if the reaper has tests around teardown/log preservation.

Acceptance

  • A reaped engineer container log includes a line like ward container reap: logs flushed to <host path> or ward container reap: no durable log flush configured.
  • The line appears in docker logs <engineer-container> output.
  • ward exec test passes.

Filed from the read-only director surface after the Goose engineer for ward#692 died and the operator needed to locate the flushed logs.

🔒 Reserved by ward agent --harness codex — container engineer-codex-ward-693 on host kais-macbook-pro-2.local is carrying this issue (reserved 2026-07-08T21:55:13Z). Concurrent ward agent runs are blocked until it finishes or the reservation goes stale (1h TTL); --force overrides.

Do not comment on or edit this issue to steer the run while it is reserved. 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).

WARD-OUTCOME: done

details

workflow: direct-to-main; review summary: skipped (review gate skipped by ~/.ward/config.yaml default)
implementation: added a container-visible reap archive line and tests for success/no-flush cases
retrospective: small code change, but the container ran out of disk during full-suite verification, so the verification path took more cache wrangling than the patch itself
confidence: medium
surprises: ward exec lint passed, the targeted go test ./cmd/ward -run 'TestReapEnvLogFlushLine|TestRunContainerReapAnnouncesLogArchive' passed, and Forgejo task 8005 is running for e296c3d after the push
follow-ups: re-run the full suite on a less space-constrained surface if task 8005 fails
