What the record says
Availability. No current finding is published for Cross-layer lead and lag because the source status is stale.
This report is scoped to cross-layer. It does not merge unlike instruments or infer a cause from co-movement.
How it was measured
each signal collapsed to a daily mean and DIFFERENCED (day-over-day change), then for every CROSS-layer pair the lag in [-7,7] days maximising |Pearson r|. Significance against a CIRCULAR-SHIFT null: one series is rotated against the other over every admissible offset (shifts within 7d of zero excluded), which preserves each series' own autocorrelation while destroying true alignment; p = (#{null >= observed}+1)/(n+1), exact and deterministic. Holm-Bonferroni step-down at alpha=0.05 across all pairs.
What this cannot establish
- Current finding withheld: freshness deadline has passed
- Lead-lag association can establish temporal co-movement but cannot establish that one layer caused another.
Palimpsest addition
Instrument brief
availability-brief · Evidence stale
Palimpsest withholds a current finding for cross-layer: the source status is stale. This is an availability brief, not a measurement.
Key number
- withheld headline metric · withheld because the source is not live
Current number and denominator
- No current number is published for cross-layer because the newsroom status is stale. The retained metric is withheld.
- No current finding is published for Cross-layer lead and lag because the source status is stale.
Same-edition board context
- Same-edition elevated layers: none declared. Other live lead or high signal ids: event-flags, ddti, undertext, ooni-gfw, in-path-interference, censored-planet, inside-view, ioda-outages, vantage-fusion, erasure-observatory, wayback, app-storefront, apple-censorship, cny-fix-gap, data-darkness, generative-firewall.
- No editorial_priority or MAD score is treated as a finding on this reading.
What this reading does not show
- Current finding withheld: freshness deadline has passed
- The brief does not assign motive, identify a person, merge unlike denominators, or treat a missing reading as a zero.

Counterreadings
- A current or withheld instrument value is not independent corroboration of any publisher article, and it is not a cause.
- Co-movement with another live signal on this edition is layer context, not a shared rate or a coordinated action.
Limitations
- Current finding withheld: freshness deadline has passed
- The companion copies newsroom templates only; it adds no interview, article body, or generative prose.
