Case 01 · Doorway Effect
Threshold Intent Collapse
Finding: Intent recall dropped 42% within 900 ms of crossing domestic thresholds; recovery was replaced by fabricated rationale in 3/5 participants.
Analyst note: Participants remembered practical reasons only after prompting, then changed those reasons during follow-up.
Case 02 · 3:17 Spike
Nocturnal Synchrony
Finding: Diary and wearable alignment showed abnormal wake clustering at 03:17 ±2 minutes across 28 nights in unrelated households.
Analyst note: Environmental controls removed obvious triggers; subjects still woke "as if resuming a task they could not name."
Case 03 · Blink Suppression
Textual Re-entry Artifact
Finding: High-contrast reading tasks produced repeated line reacquisition after long blinks, despite reported forward progression.
Analyst note: Confidence increased while actual progression fell; PDE appears to prefer smooth narration over line numbers.
Case 04 · Corridor Loop
Spatial Sequence Rewrite
Finding: Participants traversed identical corridor nodes while reporting monotonic movement; camera data contradicted all self-reports.
Analyst note: One red novelty marker reduced loop duration by 18%, suggesting sameness is operationally dangerous.
Case 05 · Device Drift
Unowned Digital Actions
Finding: Short text insertions appeared during user-absent windows under five seconds, with cadence matching local typing signatures.
Analyst note: Insertions were grammatical, semantically odd, and described by users as "technically mine, behaviorally unclaimed."
Case 06 · Name Retrieval Failure
Social Label Dropout
Finding: Familiar-name retrieval dropped in high-transition social settings; subjects reported brief "blank static" before substitution.
Analyst note: One-second pause-and-anchor scripts reduced substitutions without improving confidence ratings.
