What this PR does

The cron scheduler currently records last_status as a binary "ok" or
"error". This misclassifies a real and frequent class of runs: agent-mode
jobs that hit max_turns and write a properly-structured handoff memo
asking for the next session to take over. The memo IS the work, not a
failure.

This PR adds a third state: "handoff". The scheduler detects a
[HANDOFF] marker at the start of the agent's final response, strips the
marker before delivery, and records last_status="handoff". The CLI
renders this in yellow, distinct from green (ok) and red (error).

Changes

cron/scheduler.py (+24 lines)

• New module constant HANDOFF_MARKER = "[HANDOFF]"
• In _process_job (right after run_job returns), detect the marker:

  is_handoff = False
  if isinstance(final_response, str):
      stripped_resp = final_response.strip()
      if stripped_resp.startswith(HANDOFF_MARKER):
          final_response = stripped_resp[len(HANDOFF_MARKER):].lstrip()
          is_handoff = True

• Pass handoff=True to mark_job_run only when the marker is
  present (preserves exact call shape for existing tests using
  assert_called_with).

cron/jobs.py (+22 lines)

• mark_job_run gains a kwarg-only handoff: bool = False parameter
• Three-state branch replaces the old if success else "error":

  if not success:
      job["last_status"] = "error"      # real failure (also: handoff=True ignored)
  elif handoff:
      job["last_status"] = "handoff"    # planned checkpoint
  else:
      job["last_status"] = "ok"          # clean finish

• Defensive: success=False overrides handoff=True — a real failure
  is never reclassified as a planned stop.

hermes_cli/cron.py (+6 lines)

• last_status == "handoff" rendered in yellow (vs green ok, red
  error).
• Inline comment explains the 3-state semantics for the next reader.

tests/cron/test_handoff_marker.py (new, 5.0KB, 7 tests + 1 skipped)

• test_mark_job_run_success_ok — backward compat, success=True → ok
• test_mark_job_run_failure_error — backward compat, success=False → error
• test_mark_job_run_handoff — new behavior, success=True, handoff=True → handoff
• test_mark_job_run_handoff_with_failure_is_error — defensive, real failure wins
• test_mark_job_run_default_handoff_false — default kwarg
• test_handoff_marker_constant_exists — regression
• test_handoff_marker_distinctive — won't collide with common agent first-line responses
• test_process_job_strips_handoff_marker — skipped, pending _process_job
  signature inspection in upstream

445 passed, 1 skipped in 21.11s

No regressions in the existing 444-test cron suite. The single skip
is the integration test in this PR that requires _process_job signature
inspection (left as a follow-up since the scheduler's internal
bookkeeping has shifted between versions).

Why not bump agent.max_turns instead

We deliberately chose a structural fix over a config knob. Bumping
max_turns from 150 → 200 would only delay the same class of failure
(mid-fix budget exhaustion). The handoff-marker approach makes the
checkpoint a first-class concept: agents are taught to plan 1-2 fixes
and then handoff explicitly, with the scheduler recognizing this
intentional stop. The behavior is robust to any future max_turns value.

Backward compatibility

Zero breaking changes:

• mark_job_run(..., handoff=False) — new kwarg-only parameter, defaults
  to False. Existing callers see no change.
• _process_job does NOT add handoff=is_handoff to the call when
  is_handoff is False, so assert_called_with exact-match tests in
  the existing suite continue to pass.
• The CLI color update is render-only.
• No JSON schema changes — last_status field can now have a third value
  "handoff", but existing values ("ok" | "error" | null) are
  unchanged.

Real-world bug: how the symptom manifests

Without this PR, an agent-mode cron that hits max_turns (e.g. 150) and
writes a handoff memo would be reported to Telegram with the prefix
⚠️ Cron job failed: .... The user can't tell at-a-glance whether the
cron "ran successfully and asked for a new session" vs. "crashed with
no output". Aggregating cron health (e.g. "how many failed last week?")
also conflates planned handoffs with actual failures.

Reproduction transcript (without the fix):

$ hermes cron list
  family-budget-nightly-sweep [active]
    Last run:  2026-06-17T00:13:12 UTC  error: RuntimeError: 🚨 **Tool budget
                                                              exhausted in this
                                                              session.**...

With the fix, the same run reports handoff (yellow) and the Telegram
delivery shows the handoff memo without the ⚠️ Cron job failed: prefix.

cc @colingreig — this complements #45322 (your feat(cron): per-job max_turns override + record budget stops as PARTIAL).

Your design note says: "A distinct partial status value (for separate TUI rendering) would be a reasonable follow-up but is intentionally out of scope here to keep the change focused." — this PR implements exactly that follow-up:

Aspect	#45322	#48072 (this)
Signal	turn_exit_reason field (auto-detect)	[HANDOFF] marker (agent opt-in)
last_status	stays ok + banner	new handoff enum value
CLI render	green ok	yellow handoff
300-char floor	yes (defensive)	no (trust agent)

They're complementary, not redundant:

• feat(cron): per-job max_turns override + record budget stops as PARTIAL #45322 catches budget exhaustion automatically (no agent cooperation)
• This PR catches explicit agent handoff (planned checkpoint, regardless of budget)
• Both can fire: budget hit + agent wrote [HANDOFF] → our patch wins (detected first)

Merge order: Either order is safe. We touch cron/scheduler.py:_process_job and cron/jobs.py:mark_job_run separately from #45322's run_job changes — no overlapping hunks. A post-merge rebase on top of #45322 is straightforward.

Diff: +201 / -4 across 4 files. 445 tests pass locally. Pre-rebase of base f9c8d95e → 016bce1 (current main) done locally; will force-push shortly.

+1 from production — and one more state missing

Hit the same class of bug this morning (2026-07-09 21:03, daily-health-report 742eb8db275e): agent hit some stop condition, response was truncated to "Now writing the markdown report and HTML in parallel", mark_job_run(success=True) ran clean — last_status=ok, Telegram delivery went out (interrogated later, delivery was of the truncated text), and the promised md + html artifacts were never produced. Today the user had to manually ask to discover it. Third occurrence in ~2 months.

This PR's handoff 3rd state is genuinely useful for the "agent cleanly wrote a handoff memo" case. But it doesn't catch the case we keep hitting: agent didn't write a [HANDOFF] marker, didn't write the artifact, but success=True because the LLM stream finished. That's a 4th state distinct from handoff:

status	meaning	render
ok	agent finished cleanly, work done	green
handoff	agent wrote [HANDOFF] memo, intentionally stopped	yellow
error	LLM/transport/script raised	red
data_missing (missing from this PR)	agent finished but the cron job's declared artifacts are absent/empty	red-with-amber

The 4th state requires per-job required_artifacts list (prompt-declared, or job-config-declared), which is a separate surface from mark_job_run's marker. Happy to take that as a follow-up PR if maintainers want — would use this PR as the seam.

Even without the 4th state, the handoff branch lands as the first non-binary signal — please don't let it sit. Suggestion for prioritization: land this PR as-is, then a second PR that:

• adds required_artifacts: list[str] | None to job config
• adds data_missing to the 3-state branch
• adds a last_artifact_check audit timestamp on jobs

Two PRs kept narrow is much easier to merge than one PR with three concerns. Will defer to your call.

Thanks for the focused handoff-status proposal. The feature is still absent on current main: mark_job_run() remains binary at cron/jobs.py:1485.

Problems

• The implementation is based on an obsolete scheduler layout. Current cron/scheduler.py:3637-3642 makes _process_job a thin wrapper; the shared execute→save→deliver→mark path is run_one_job() at cron/scheduler.py:3452-3532, also used by external providers. The marker/status logic must be ported there rather than salvaging the old body.
• The only pipeline test is skipped in tests/cron/test_handoff_marker.py:131. It needs to exercise the current shared path and assert marker-free delivery plus persisted handoff status.

Suggested changes

• Rework the patch around run_one_job() while preserving its interruption and empty-response guards.
• Replace the skipped skeleton with an active end-to-end unit test for the marker path.

Automated hermes-sweeper review.

[teknium1]

This is the only test tying the marker to scheduler behavior, but it is permanently skipped and targets the old _process_job body. Please replace it with an active run_one_job()/tick() test that verifies marker-free delivery and the handoff status write through current main's shared pipeline.
