Narrative Time-to-Contain (NTC)
How quickly a forming story is buried. Past a threshold, a narrative reaches escape velocity and cannot be recalled.
Formula
Thresholds & Bands
| Band | Range | State |
|---|---|---|
| Fast | < 12 | ok |
| Slow | 12-36 | warn |
| Viral | > 36 | crit |
Why This Metric Matters
Narrative Time-to-Contain is the Directorate's single most sensitive indicator of information-environment control. Once a hostile narrative crosses the 36-hour mark, PANACEA modeling shows it achieves a self-reinforcing amplification loop that no downstream intervention can reliably collapse. Rapid containment preserves the credibility architecture that every other PANOPTICON program depends on. A slow NTC degrades public trust scaffolding, increases Compliance Index volatility, and forces costly escalation to kinetic narrative-suppression protocols.
Threshold Justification
The 12-hour fast-containment ceiling was derived from Chorus sentiment-propagation models calibrated against 847 narrative events between 2024 and 2026. Below 12 hours, counter-narrative injection achieves greater than 94% suppression before secondary amplification. The 36-hour critical boundary marks the empirically observed inflection point beyond which recall probability drops below 30%, per PANACEA Bulletin PAN-ANA-2025-071.
Historical Context
At initial deployment in Q2 2024, median NTC stood at 28 hours. Following the integration of Chorus real-time sentiment scraping and automated counter-narrative generation, the median fell to 9.4 hours by Q4 2025. Seasonal spikes remain correlated with regulatory-calendar events and product-launch windows, where hostile-narrative volume increases by approximately 3x baseline.
Collection Method
NTC is computed by PANACEA's Chorus subsystem, which ingests streaming data from social-media firehoses, broadcast-transcript feeds, and VITALNET biometric sentiment proxies. Narrative detection triggers are defined by threshold crossings in the Chorus Hostility Index. Containment is confirmed when the narrative's reach-velocity falls below the self-sustaining propagation threshold for two consecutive measurement windows.
Known Failure Modes
NTC can produce falsely optimistic readings when a narrative is suppressed on monitored channels but migrates to unindexed platforms outside Chorus's ingestion perimeter. Encrypted messaging networks and peer-to-peer distribution remain persistent blind spots. Additionally, coordinated narrative launches timed to coincide with Chorus maintenance windows have historically produced delayed detection, inflating apparent containment speed for events that were in fact detected late.
