Input and reference-frame workflow

Uncertain-time interval construction

Represent imprecise event time as a bounded interval and feature-stability problem.

Required inputs

Earliest defensible instant

Latest defensible instant

Evidence for each bound

Requested chart features

Ordered execution

Work the protocol

  1. 1

    Reject false minute precision.

  2. 2

    Construct a closed uncertainty interval.

  3. 3

    Evaluate each requested feature across the interval.

  4. 4

    Retain stable features and withhold unstable ones.

  5. 5

    Version a new interval only when new evidence arrives.

Outputs

  • Time interval
  • Feature stability table
  • Withheld-feature list

Done only when

  • Every feature is stable or withheld.
  • Interval provenance is explicit.
  • No precise-looking chart overrides the source.

Fail closed

Refusal conditions

  • A midpoint is presented as observed.
  • Rectification is treated as source evidence.
  • No basis exists for either interval bound.
