Destinations · measurement baseline
Metric availability
Nine fields across nine documented destinations create 81 modeled classifications. They do not guarantee current non-null measurement coverage.
Eighty-one cells
Availability matrix
Each cell is an exact modeled state. Field values remain separate from their availability classification.

State rules
availableThe modeled baseline says the platform exposes this field.
delayed(2-3d)The field is expected after a two-to-three-day evidence delay.
estimableSuitable evidence could support a derived value.
neverThe platform does not expose this field.
unverifiedNo observed Postdom response has verified this field.
Baseline and observation
Verification boundary
Classification, not coverage
The original baseline was recorded on 21 August 2026. Operational setup was checked on 22 August 2026; no fresh per-platform analytics were available. Later rows retain their own evidence dates or remain explicitly unverified.
LinkedIn, Bluesky, Snapchat, and Threads remain unverified across all nine normalized fields. TikTok and Instagram saves remain unverified; YouTube saves is never and its retention fields are delayed. For the difference between null and zero, read the completion-rate glossary.
Value preservation
Agent behavior
Preserve zero
Zero is numeric evidence and remains zero.
Preserve null
Never and unverified include reasons. Other nulls may not.
Where classified as estimable, follower_delta is still normalized to null. Destinations classified as unverified remain unverified. Do not invent a derived value.
