explain endpoint response. When Heretic evaluates a session, it collects signals across up to six families and combines them into a single verdict.
Signal ID format
Signal IDs follow the patternfamily-prefix.descriptor — for example, geo.rtt-below-vacuum. The prefix maps to the evidence family that produced the signal, and the descriptor names the specific contradiction or observation. Because signal IDs are stable, you can safely key policy rules on them without worrying about renaming between releases.
Signal catalogue
The table below lists every signal currently in the catalogue. The Tier column tells you how the signal contributes to a verdict: anabsolute signal is sufficient on its own; composite signals are strong but benefit from corroboration; conditional signals apply only when supporting context is present; weak signals contribute but never dominate.
Evidence families
Each signal belongs to one of six evidence families. Heretic reads families independently so that a spoofed value in one family cannot suppress a contradiction detected in another.Signal tiers
The
tier field in every API response tells you the tier for each signal present in that session. You can read it at session.signals[n].tier.The signal catalogue may expand as new measurement techniques are added. Signal IDs are stable and safe to key policy rules on — existing IDs will not be renamed or removed.
