Description

Session Goal

Stabilize the accounting automation flow for debt, metrics, and front report generation, while diagnosing path-resolution and front-factory issues that were preventing reliable execution.

Key Activities

• Reviewed the correct execution order for the accounting pipeline: materialize debt artifacts first, then generate metrics, and only after that build the front report.
• Identified that the front report depends on metrics_dir, which in turn depends on debt artifacts already being generated.
• Diagnosed two workflow failures:
  • a Python module import error caused by an incorrect working directory
  • a mislocated CSV path for debt open-items generation
• Collected and refined ready-to-run CLI commands for producing prudential, executive, full, and minimal front reports.
• Investigated a local bug in build_kpi_cards() where fallback selection used or across values returned by _pick_row(), triggering pandas Series truthiness errors.
• Proposed a safer implementation using a _first_present() helper to avoid ambiguous boolean evaluation and make KPI fallback logic deterministic.

Achievements

• Clarified the dependency chain for the accounting run and the minimum validation checks needed before freezing a run.
• Narrowed the path-resolution issues to specific execution context and CSV location problems.
• Isolated the KPI card crash to a concrete pandas truthiness bug and defined a conservative patch strategy.
• Established a practical rerun path for generating front reports once metrics are validated.

Pending Tasks

• Apply the _first_present() patch in build_kpi_cards() and rerun the front factory.
• Verify that load_context() is not leaving debt metrics empty due to the suspicious path reference.
• Re-run the accounting pipeline end-to-end in the correct order and confirm the generated HTML outputs for prudential, executive, and full front reports.
