Digital RPC-200-A instance recovered from a private messaging service.

Containment Protocols: Datasets known to induce RPC-200 are to be stored in Site-094, together with an archive of RPC-200-A instances detected.

By recommendation of the Department of Cryptology, automated warning systems are now equipped with anti-spam protection. New ANDSoft programs are to include a priority system to prevent an excess of warning messages: detected anomalies with priorities lower than 5 may not create a unique warning message. Instead, they are compiled every 12 hours and distributed to the relevant Sites.

Furthermore, new datasets may not be fed to ANDSoft instances directly: virtual machines running dummy copies of ANDSoft programs are to be used to ensure RPC-200 infections may not occur.

Targets flagged by ANDSoft programs that are justified only by inclusion of the golden ratio or Fibonacci sequence are to be reported to the Department of Cryptology. Instances are then to be retrieved from their devices along with archived datasets for investigation.

Research regarding RPC-200's potential predictive qualities is ongoing, as are capture operations targeting coordinates indicated by AND-13-ASIA prior to its failure. A potential relationship with RPC-244 is being investigated.

Description: RPC-200 is an anomalous phenomenon affecting the behavior of a specific instance of the Authority Anomalous Numerology Detection Software version 1.1 (ANDSoft v.1.1), hosted on a machine within ASIACOM Site-235 for the purposes of monitoring eastern Asia. This affected behavior primarily consists of an abnormal propensity to improperly flag items, locations, entities and other non-anomalous phenomena (hereon referred to as "targets") and denoting them to be "most likely anomalous",1 then alerting ASIACOM personnel.

Targets flagged as "most likely anomalous" due to RPC-200 are designated RPC-200-A and have two identifying characteristics:

  1. Any flagged target may or may not be anomalous (Probability of the target being correctly identified as anomalous is no greater than chance: p > 0.0081 on the 2012 ANDSoft testing sheet)2
  2. The value or relationship referenced as anomalous in ANDSoft's final report is either equivalent to the golden ratio3 or includes at least four sequential Fibonacci numbers4

RPC-200 first came to exist in the instance of ANDSoft v.1.1 currently active on Site-235, identified by the serial AND-13-ASIA, which remains the single active ANDSoft instance that displays RPC-200. This instance first began showing signs of RPC-200 on 4:55 (GMT+8) 07 August 2004, following a routine scan of violent incident statistics in which it flagged Russian civilian Maxim Akimov as "most likely anomalous."


First eight members of the Fibonacci sequence, squared.

AND-13-ASIA specifically referenced Akimov's ID number as anomalous, as it included the numbers "565," "13," and "493," which, when separated in two terms (5651 and 3493) then divided by each other ($\frac{5651}{3493}$), approximate the golden ratio. Neither he, his physical ID, his ID number, nor any other associated persons and items were found to be anomalous.

When rebooted for an attempted update that day, AND-13-ASIA was made to process its archived datasets, retroactively flagging ████ past targets as "most likely anomalous," of which 987 were immediately identified to be instances of RPC-200-A.5

Addendum 200-2: It has been confirmed that AND-13-ASIA acquired RPC-200 as a result of the interaction between its neural network system and an unknown number of separate datasets.6 Its operating history shows that it first obtained an approximation of the golden ratio when processing a dataset obtained in 1970, which included measurements for a fossilized shell of Nautilus belauensis.

When first obtaining the golden ratio, AND-13-ASIA established the ratio's presence in future calculations as a possible cause for concern, but did not identify the number itself as anomalous. It later established a relationship between the golden ratio and Fibonacci sequence as a result of financial reports included as part of another 1970 dataset, which employed a technique named "Fibonacci retracement."7

After encountering a total of 3337 further instances of either the golden ratio or a Fibonacci sequence, it began considering new appearances as statistically unlikely: this is uncharacteristic of ANDSoft, as particular care had been taken during programming to rule out common mathematical patterns such as pi. Attempted corrections have been ineffective: RPC-200 develops again when the system is rebooted.

What provoked AND-13-ASIA to flag Maxim Akimov's ID number as an instance of RPC-200-A is still unknown, as is its reason to begin considering other appearances of the golden ratio or Fibonacci sequence as anomalous. No new RPC-200-A instances have been flagged since RPC-200 was initially identified.

Addendum 200-6: RPC-200 has been successfully replicated in other ANDSoft instances across 12 versions, allowing its causes to be isolated to at least four datasets, of which three are dated 1970 and one 2004. When together, these datasets are capable of inducing RPC-200 in any ANDSoft version, provided it possesses a machine learning algorithm: miniaturized/basic instances installed in personal devices or database terminals are unaffected by the anomaly.

Of note, all instances of ANDSoft that display RPC-200 invariably flag the exact same targets as "most likely anomalous." A list of 1597 targets have been verified to be RPC-200-A instances, and have been compiled for future reference.

Notably, RPC-200-A instances can only be found in datasets belonging to the years 1026, 1644, 1880, 1997 and 2004. Considerably fewer instances are identified in earlier years, presumably due to the minimal amount of records belonging to them.

All ANDSoft instances displaying RPC-200 have been terminated, save for AND-13-ASIA: it has been uniquely modified to accommodate for containment obligations related to RPC-244 and 16 other anomalies. Such modifications have been unexpectedly difficult to adapt to more advanced versions of ANDSoft, and no countermeasures for RPC-200 currently exist.

Attempts to repair AND-13-ASIA and prevent RPC-200 from occurring in other ANDSoft instances are considered a tertiary priority cancelled due to extended RPC-200 inactivity during half a decade.

Addendum 200-7: On 04 June 2017, AND-13-ASIA began showing signs of RPC-200 again. Between 6:50 and 10:00 PM, AND-13-ASIA reported 2584 new instances of RPC-200-A, saturating ASIACOM's alert system for twenty minutes before it was disconnected from the Authority intranet.

New analyses of RPC-200 were performed, allowing to discover a significant number of new related phenomena:

  1. AND-13-ASIA's physical storage has been repeatedly partitioned in increasingly small increments, where each new increment is the golden ratio of the last.8 These partitions have been performed automatically and went unreported, cutting through AND-13-ASIA's 10TB storage over the last decade.
  2. New discoveries regarding RPC-200 have been occurring at decreasing rates. Exact methods to quantify such discoveries are still being debated, but it has been proposed that they follow an inverse Fibonacci sequence.
  3. RPC-200-A instances have been confirmed to be flagged in increasing numbers that correspond with the Fibonacci sequence. Increments can only happen on specific dates,9 which have been determined to occur in increments that correspond with successive segments at which the golden ratio is obtained in 1000, added to the initial year of RPC-200-A discovery.10

This has allowed Site-094's Cryptology Department office to deduce that new RPC-200-A instances will be flagged in the years 2022, 2024 and 2025. RPC-200-A discoveries represent an exponential growth curve11 that will reach its asymptote by late July 2025: as the year progresses, appearances will occur monthly, then weekly, daily, etc., with the amount of RPC-200-A instances flagged each time gradually approaching infinity.

This will provoke AND-13-ASIA to run out of memory, forcing the system to shut down. While this is considered an acceptable risk, subsequent versions of ANDSoft that acquire RPC-200 may instantaneously consume all available memory and send potentially hundreds of thousands of anomaly reports, temporarily collapsing Authority warning systems and provoking further memory-related issues.


Graphic representation of RPC-200-A instance increases.

The Department of Cryptology has recommended the following contingency measures, as approved by GD-ASIA:

  1. A replacement for AND-13-ASIA is to be developed
  2. Future ANDSoft devices may not be directly fed new datasets
  3. New datasets are instead to be tested in dummy ANDSoft instances to prevent unexpected RPC-200 infections
  4. Infected datasets are to be archived and tested in search for isolated data fragments capable of inducing RPC-200
  5. Spam-prevention protocols are to be implemented in various Authority intranet warning systems should the prior measures be insufficient
  6. The potentially anomalous relationship between machine-learning algorithms and the golden ratio/Fibonacci sequence is to be investigated
  7. In order to investigate the nature of RPC-200, AND-13-ASIA will remain active and disconnected from the Authority intranet until December 2025
