The engine orchestrator. compute_pnl, compute_balance_sheet,
compute_trial_balance, compute_gl, drill_down. All controllers,
wizards, AI tools must route through these methods; no direct
SQL aggregation from anywhere else.
Internal pipeline: validate -> fetch hierarchy -> SQL aggregate
-> resolve line_specs -> optional comparison + anomaly. Uses raw
SQL for the per-account aggregate (the perf-critical step), ORM
for everything else.
Per-company report lookup with global fallback (company_id desc
nulls last). Balance sheet uses 1970 epoch as date_from for
cumulative-since-inception semantics.

Persistent definition of a Fusion financial report. Each report (P&L,
balance sheet, trial balance, GL) has one row in fusion.report holding
its metadata + line specs (stored as JSON for layout flexibility).
V19 conventions: models.Constraint inline, no _sql_constraints. Per-
company uniqueness on (company_id, code).
