Held the denim discount ceiling at 25% through the competitor overlap.
Ana recommended tightening to 20% — we held wider. Margin gap grew as forecast; the reversal happened three weeks later.
Context
What was in the room.
The source recommendation and the situation as it was understood at the moment of decision. Frozen — this is what the decision was actually made on.

Tighten the discount ceiling to 20% and review the pricing override log with the denim buyer.
Rationale
Why it was decided.
The accountable owner's reasoning for the verdict. One paragraph; the record of judgement, not a defence of it.
The buying team wanted to match the competitor calendar for two more weeks to protect the seasonal handover. Accepted the risk of a wider margin gap on the read.

What Ana learned
The lesson, in one paragraph.
The pattern Ana takes from this decision into the rest of the organisation's memory.
The lesson
When competitor overlaps run more than 14 days, the marginal cost of matching begins to compound at ~1.2× the linear model. The 20% recommendation was correct — the seasonal-handover argument did not offset the margin drag.
Applied from now on
Competitor-overlap prompts will now attach a compounding-cost table to the recommendation, and Ana will flag the crossover date when linear modelling stops holding.
