name: paperlab_case_thread_continuity description: | Maintain consistency for recurring field, facility, and design cases across PaperLab books. Use when a book uses a repeated scenario as a teaching thread and assumptions must not drift silently.

PaperLab Case Thread Continuity

When to Use

USE WHEN: chapters reuse the same field, facility, well, pipeline, process, or economic case across theory, notebooks, exercises, and capstone studies.

Pair with:

paperlab_chapter_flow_editor for narrative transitions,
paperlab_book_knowledge_graph for case graph links,
paperlab_notebook_regression_baselines for computed case outputs.

Registry Fields

Track recurring case parameters with:

case id and public display name,
parameter name and unit,
base value and uncertainty range,
source or chapter of origin,
scenario tag,
intended teaching role,
confidentiality status.

Drift Classes

Class	Meaning
intentional-scenario	value changes because scenario changes
rounding	harmless numerical rounding
stale-value	old value remains after later update
naming-drift	same object has multiple names
contradiction	incompatible values without explanation

Output Schema

{
  "case_id": "ultima_thule",
  "parameter": "export_pressure_bara",
  "values": [
    {"chapter": "ch26", "value": 120.0, "unit": "bara"},
    {"chapter": "ch31", "value": 150.0, "unit": "bara"}
  ],
  "classification": "intentional-scenario",
  "required_note": "Explain that Chapter 31 evaluates the high-pressure export case."
}

Safety Rules

Protect private case identifiers and document names.
Do not collapse uncertainty ranges to one number.
Do not erase scenario variation that supports teaching.
