Overview / Motivation

Auto-filed by the workflow-fix-on-bug protocol from a workflow-fix candidate raised on task #922 (emitting agent: experiment-implementer, round 1).

Goal

Make tests/test_shared_vm_thread_caps.py green on main: delete the fixed entry from GRANDFATHERED_895 and either fix or explicitly grandfather (with issue refs) the current main-side violators.

Workflow gap

• Bug observed: test_grandfathered_895_block_is_current and test_no_new_torch_before_dotenv_vm_entrypoints FAIL on current main — scripts/issue779_heldout_recon_scatter.py was fixed (dotenv now precedes torch) but never removed from GRANDFATHERED_895, and several post-#895 entrypoints (issue779_arm_headline_summaries2.py, issue810_analyze.py, ...) violate the detector without being grandfathered.
• Why it is a workflow gap: a workflow-invariant test that is red on main FAILs every task's Step 9c test-verdict regardless of the diff under review, training sessions to dismiss it as noise.
• Confidence (emitter): high

Proposed change (candidate diff sketch — refine in planning)

• "scripts/issue779_heldout_recon_scatter.py", # in GRANDFATHERED_895 — root cause fixed on main

• (removed — dotenv-before-torch fixed on main)

• plus: reorder load_dotenv() before torch/numpy in the listed violators OR add them

• to GRANDFATHERED_TORCH_BEFORE_DOTENV with their owning-issue refs.

Scope / surfaces

• Primary target: tests/test_shared_vm_thread_caps.py
• Grep the workflow surface for the pattern before editing (grep -rln 'GRANDFATHERED_895' .claude/ CLAUDE.md scripts/ tests/) and update every hit; list them in the plan. The violator scripts themselves (scripts/issue_.py) are experiment entrypoints — the fix there is the mechanical dotenv-before-torch reorder OR an explicit grandfather entry, whichever the planner judges lower-risk per file.

Constraints / invariants

• Workflow-surface only for the test file; violator-script edits limited to the import-order reorder.
• Full test file green on main after the change; ruff passes.
• This session runs under EPM_WORKFLOW_FIX_SESSION=1 and carries a workflow_fix_target: Provenance line — it MUST NOT auto-route any of its own subagents' workflow-fix candidates (recursion guard).
