Occurrences across history
Long before modern instrumentation, chroniclers described abrupt memory seams, lost intention, and uncanny timing clusters. C.I.S.A. now treats these accounts as early evidence streams rather than folklore.

Continuity disruptions through the ages
-
Prehistoric mark recursion
Excavation teams found repeated eye-and-threshold motifs separated by centuries yet arranged in nearly identical sequence: eye, doorway, split path, return mark. Archeologists called it ritual art. C.I.S.A. calls it the oldest known flowchart for "why did I walk over here."

Repeated eye-and-threshold symbols in cave walls suggest a shared interruption narrative. -
Medieval monastery records
Monastic scriptoria accidentally pioneered interruption studies by obsessively documenting routine. Margin notes describe "empty instants," missing words, and repeated initials written twice in nonadjacent lines. Supervisors initially blamed drowsiness until the same error signatures appeared in fully rested scribes.

Scriptoria logs mention "empty instants" where scribes resumed writing mid-line with no remembered pause. -
Oral threshold warnings
Multiple oral traditions warned travelers to speak intention aloud before crossing night boundaries such as river banks, village gates, and tree lines. This practice was framed as spiritual etiquette; operationally, it behaves like a modern anchor script with excellent compliance and zero hardware cost.

Oral histories warned travelers to announce intent before crossing boundaries at night. -
Sleep-window anomalies
Court astronomers and household clerks independently logged synchronized wake events that mapped to narrow minute windows. Officially, records cite atmospheric omens. Unofficially, several notes complain that everyone was awake for no good reason and very offended about it.

Court astronomers recorded synchronized wake events that repeatedly mapped to identical minute windows.
Instrumentation era
The 20th and early 21st centuries transformed interruption research from anecdote to measurable signal. Prototype devices from this period were eventually merged into the C.I.S.A. standard stack. Once synchronized clocks, low-latency sensors, and shared protocol sheets became common, "strange feelings" finally turned into datasets nobody could ignore.



The founding of C.I.S.A.

In 2008, independent labs unified their methodologies under C.I.S.A. to reduce conflicting taxonomies and duplicated experiments. This alliance created standardized protocols, shared archives, and cross-site replication teams that remain active today.
The founding charter deliberately banned heroic language and encouraged boring paperwork, based on the radical premise that subtle phenomena require disciplined notes rather than dramatic personalities. Members may disagree on causes, but they agree on one thing: if it was not timestamped, it did not happen.
