Build a paid-campaign calendar sequenced around real fatigue signals, not a fixed weekly slot

Build a paid-campaign calendar for the period below. Every scheduled action must be triggered by a stated performance or timing signal — not placed on a fixed cadence just because a calendar needs entries in every week.

CAMPAIGNS RUNNING OR PLANNED
Meta ads for the fall product line (ongoing), Google Search brand campaign (always-on), planned LinkedIn campaign for a new webinar series.

CREATIVE FATIGUE HISTORY
Meta creative historically shows CTR decline starting around day 10-12 of a given ad set; Google Search brand terms rarely fatigue since they're intent-driven.

BUDGET REVIEW CADENCE
Budget reviewed every other Friday with the finance lead.

KEY BUSINESS DATES TO BUILD AROUND
New product line ships Oct 1; no new campaign launches want to overlap with the Oct 1 week's operational load.

For each campaign, schedule the creative refresh based on the fatigue pattern in creative_fatigue_history rather than an arbitrary fixed interval — if history shows this channel's creative typically fatigues (CTR decline of a certain magnitude) around a known point, schedule the refresh check just before that point, and say so explicitly rather than defaulting to a round-number cadence like "every 2 weeks" that isn't actually tied to this channel's real decay pattern. Do not schedule a budget review on the same day as a creative refresh unless there's a specific reason to bundle them — reviewing budget and refreshing creative are different decisions that get made worse when rushed together under one calendar slot. Build key_business_dates into the calendar as hard anchors the rest of the schedule must work around, not as an afterthought layered on top — if a launch or refresh would otherwise land in the same week as a key business date, move it, and say which way you moved it and why. If two campaigns would compete for the same audience's attention in the same week without a stated reason for that overlap, flag it explicitly rather than let a busy week for one audience pass silently.

OUTPUT FORMAT
A week-by-week calendar table: Week | Campaign | Action (launch / refresh check / budget review / pause) | Trigger reason for that timing. Below the table, list any key business date that forced a scheduling move, and any audience-overlap conflict you flagged between two campaigns.
