Overview / Motivation
Auto-filed by the /daily 2026-07-08 problem sweep (transcript-mined; emitting agent: /daily orchestrator).
Goal
Decide (in-pipeline) whether a WARN-grade ladder-without-retention check is worth mechanizing; ship it if yes.
Workflow gap
- Bug observed: Transcript ef9063d8 (issue-1133) 09:21:43Z: the planner surfaced an optional verify_plan check for ladder-without-retention but judged a regex detector fragile ("plans phrase ladders many ways") and deferred it — the /daily classifier routes deferred-but-concrete candidates for the pipeline planner to decide with the file open.
- Why it is a workflow gap: The #1112 ENOSPC class is now rule-covered but has no mechanical backstop; verify_plan checks are WARN-capable, so a low-precision detector can still be net-positive.
- Confidence (emitter): medium
Proposed change (candidate diff sketch — refine in planning)
A c-series WARN check: plan mentions a per-rung/checkpoint ladder token set AND no retention/disk-bound token within the compute-sizing section => WARN with the #1133 rule pointer. The spawned planner may deflect with a reasoned no-change report.
Scope / surfaces
- Primary target:
scripts/verify_plan.py - Grep the workflow surface for the pattern before editing and update every hit; list them in the plan.
Constraints / invariants
- Workflow-surface only — never experiment code,
configs/, ortasks/. scripts/workflow_lint.py --check-asks+--check-referencespass; ruff on touched files passes.- This session runs under
EPM_WORKFLOW_FIX_SESSION=1and carries aworkflow_fix_target:Provenance line — it MUST NOT auto-route its own subagents' workflow-fix candidates (recursion guard).
Provenance
- workflow_fix_target: scripts/verify_plan.py
- origin: transcript-mined by /daily 2026-07-08 problem sweep
- evidence: mine-C U2 (ef9063d8 09:21:43Z)
