Data quality flag — this report contains a known defect
A median_salary Trend value was displayed where job_postings_count was intended (e.g. 'snowflake mentions moved +15000 this week, to 172500' — 172500 is a median salary, not a mention count). Root cause: Trend queries in ReportingAgent filtered by period but not by metric. Fixed 2026-08-15 (see docs/MAINTENANCE.md, tests/test_metric_isolation.py). The underlying job_postings_count data for W30 was never wrong -- only this report's narrative text. Left unedited rather than silently corrected; flagged here instead.
Week of Jul 20–26, 2026: software engineer mentions rose from 0 to 29. Weekly counts here swing widely, so read this as a snapshot, not a trend.
Window: Jul 20–26, 2026 to Jul 20–26, 2026.

- Only the configured sources are represented. Everything else is absent, not zero.
