+// Command normalize-recording-cutover-depletion
+//
+// Data-only normalization of recording population metrics for a cut-over flock
+// where pre-cutover mortality (culling + dead) was booked via stock adjustments
+// (which do NOT feed the recording population). It applies an "opening depletion"
+// offset to the CUMULATIVE depletion of every recording in a project_flock_kandang,
+// recomputing the population-dependent metric columns DIRECTLY on the `recordings`
+// table.
+//
+// It does NOT touch recording_depletions, stock_allocations, product_warehouses,
+// project_flock_populations, or adjustment_stocks — so inventory/FIFO stay intact
+// (the existing adjustments keep owning the stock movement).
+//
+// Recomputed columns (per recording, ordered by record_datetime,id):
+//
+//	cumDepByDate = running SUM(recording_depletions.qty) up to that recording (INVARIANT)
+//	new_tcq            = initialChickin - cumDepByDate - opening
+//	cum_depletion_rate = (cumDepByDate + opening) / initialChickin * 100
+//	feed_intake        = feed_intake_old * (old_total_chick_qty / new_tcq)   [null->null]
+//	fcr_value          = fcr_value_old   * (old_total_chick_qty / new_tcq)   [null->null]
+//
+// cum_intake and egg-based metrics are left untouched (see plan).
+//
+// Idempotent: only rows where total_chick_qty IS DISTINCT FROM new_tcq are updated.
+// Self-check: run with -opening=0; consistent rows are no-ops, any row that changes
+// was already inconsistent (stale) and gets reconciled to follow the depletion data.
+//
+// Usage:
