CASE-1993 CLOSED opened 1993-02-09 · last reviewed 1994-11-02

Nineteen Hours at ARGENT

Post-incident assembly of the loss-of-reference event. Closed with procedural changes; not closed with comfort.

Uncertainty is part of the file. Fictional institutional record — not a real-world claim.

Known

  • External reference was lost for approximately nineteen hours.
  • Local oscillators continued; disagreement was not treated as an instrument state.
  • Procedural changes followed (SEN-93-112).

Unknown

  • Whether any observations from the window remain mis-timestamped in secondary copies.

Open questions

  • Do any secondary copies still carry timestamps from the unverified window?

Competing explanations

  1. Single failed oscillator — rejected as incomplete.
  2. Organisational confidence in an unverified reference — retained as the teaching finding.

Evidence

  1. SEN-93-112
  2. SEN-16-007
  3. SEN-98-003

Counter-evidence / limits

  • No public evidence that a single failed oscillator alone caused the nineteen-hour window.

  2. 1994-11-02 — Closed; teaching note retained in SEN-93-112

Current status / finding

Closed. Root cause was organisational confidence in an unverified reference, not a single failed oscillator.

Institutional fiction. Uncertainty is retained on purpose — do not read a finding as a real-world claim.

Timeline consistency — ARGENT loss of reference

Four dated notes about the 1993 ARGENT incident were indexed without order. One ordering makes the procedural finding legible.

Objective Enter the event codes in chronological order, comma-separated (e.g. W,X,Y,Z).

Clues

  • W — 1994-11-02 — Closure: timing treated as instrumented state (SEN-93-112)
  • X — 1993-02-08 — Incident window
  • Y — 1993-02-09 — Case opened
  • Z — 2016-03-22 — Experiment Delta holdover results filed (later teaching use)
Hint

The incident precedes the case opening by one day.

Second hint

Closure is 1994; Delta is a later related experiment, not part of the incident week.

Accessible path (no interaction required)

Chronological order: X (1993-02-08), Y (1993-02-09), W (1994-11-02), Z (2016).
