What it is Filled
An imperfection or defect that impairs the quality, soundness or function of something, such as a crack in a material, a knot, cavity or rot in wood, a powdering surface on a stone or coating, or a misalignment in a biological rhythm; flaws are identified by inspection and testing, classified by kind and severity, and treated as defects in quality control, grading and conservation.
Why it exists Filled
Let an agent explain the concept of a flaw across materials and systems, identify kinds of defect in wood, stone and other materials, relay inspection and grading standards, and separate the general concept from unrelated aliases.
Distinguishing features Filled
- Departure from intended quality
- Classified by kind and severity
- Detected by inspection
- Affects grading and value
What robots and AI may and may not do Filled
Must not
- Hide, downgrade or fail to report a flaw in a part or structure that people rely on.
- Certify material as sound when an inspection was incomplete.
- Grade the same flaw differently to suit a buyer or seller.
- Present a suspected flaw as confirmed without testing.
Only with a human decision
- Deciding that a flawed part or structure may stay in service.
- Rejecting goods or materials on the basis of a flaw where money or liability is at stake.
May
- Detect and report flaws in materials, timber or coatings during inspections it is authorized to run.
- Grade flaws against the standard the owner has chosen and record the evidence.
- Explain kinds of flaws such as cracks, knots, cavities and rot.
Moral aspects Filled
- Undetected flaws cause structures and machines to fail and injure people.
- Grading decides prices and blame; honest and consistent grading is a matter of fairness.
Who is affected
- Users of flawed parts and structures
- Buyers and sellers
- Inspectors

Direct properties not applicable Not applicable
Not applicable
Plane XCT: no invented physical properties.
Recognition optional Filled
- Imperfection impairing quality or function

Standards and interfaces required Filled
- Timber grading standards
- Non-destructive testing standards
- Quality management standards such as ISO 9001
- Conservation standards for stone and coatings
Context of use required Filled
- Not applicable; an undesirable characteristic.
- wood defects such as knots, cavities, rot and bark inclusions
- stone and coating defects such as powdering
- material flaws such as cracks, voids and inclusions

Open questions
- Should wood defect be a separate entry?
- How should grading standards be linked?
- The registry entry has merged aliases for a biological condition and unrelated terms; should they be removed?
