hilum
Enable an agent to identify a hilum in its biological context, record its boundaries and condition, and select appropriate observation or specialist assessment.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Hilar meaning Resolve what hilum denotes before applying structural or functional expectations.
Documented sense
Select a meaning supported by biological context.
Multiple biological usages
Botanical terminology includes seed scars, starch-grain reference points, and spore attachment features under hilum; these require separate recognition criteria. See [Missouri Botanical Garden terminology](https://www.mobot.org/mobot/latindict/keyDetail.aspx?keyWord=Hhilum).
- Which documented biological meaning applies to this instance? definition
- What registry provenance or specimen context supports that choice? provenance
Host and instance
Bind the feature to a particular containing structure.
Feature ownership
Require a host reference and distinguish a particular observed hilum from a general description of hila.
- Which seed, organ, grain, or other structure bears this hilum? boundary
- Does the evidence describe this specimen or only its biological type? provenance
Seed attachment scar Apply seed-specific recognition only when the seed sense is supported.
Attachment origin
Establish why the observed mark qualifies as a hilum.
Former seed attachment
In seed terminology, the hilum marks the former attachment to the funiculus or placenta. See [Missouri Botanical Garden terminology](https://www.mobot.org/mobot/latindict/keyDetail.aspx?keyWord=Hhilum).
- What supports interpreting this mark as an attachment scar? definition
- Is the attachment history observed directly or inferred from a reference? provenance
Seed surface boundaries
Separate the scar from neighboring seed features.
Scar delimitation
Record which visible margin belongs to the hilum and which belongs to an adjacent feature or damaged seed coat.
- How is this hilum distinguished from the micropyle, raphe, outgrowths, and abrasions in this host? boundary
- What are the scar's length and width under the stated boundary convention? measurement
- Would another view or greater magnification resolve its uncertain edge? action
Organ hilar region Apply organ-specific localization and connection mapping when the anatomical sense is supported.
Organ localization
Locate the hilum relative to the organ surface and surrounding anatomy.
Host-specific hilar boundary
Require a named organ, side where applicable, and an explicit boundary convention; distinguish the surface region from its depiction in an image.
- Which organ and side contain the hilum being described? definition
- Does the annotation delimit the anatomical region or an imaging contour? boundary
Hilar connections
Record associated structures individually and according to evidence.
Observed crossing structures
Distinguish a structure demonstrated to cross the hilar boundary from one merely adjacent to it; avoid transferring one organ's arrangement to another.
- Which structures are demonstrated to enter or leave through this region? boundary
- What observation establishes each connection and its orientation? provenance
- Which expected connections remain unobserved? measurement
Hilar observation Make identification and measurement interpretable across specimens and methods.
View and scale
Record how the feature became visible and how measurements were obtained.
Measurement interpretability
Tie hilar dimensions to the selected sense, calibrated scale, viewing plane, and visible boundary.
- What method, viewing plane, and scale produced this observation? measurement
- Is the measured extent complete, projected, or partly hidden? boundary
Condition and artifact
Separate visible alteration from its possible explanation.
Interpretable hilar condition
Describe disruption, deformation, or obscuration without assigning an unsupported cause or functional consequence.
- Which hilar features are visibly altered, and against what matched reference? measurement
- Could sectioning, drying, handling, or imaging account for the appearance? provenance
- What additional observation would distinguish specimen condition from artifact? action
Hilar interpretation and use Connect supported observations to identification, comparison, and next actions.
Matched comparison
Select comparisons that preserve biological meaning.
Comparable hilar features
Compare instances only after aligning their biological sense, host, developmental context, and observation method.
- Do the compared hila share the same biological meaning and compatible host context? boundary
- Which morphological differences remain after accounting for scale and preparation? measurement
Evidence-limited action
Choose the next step according to what the hilar evidence actually establishes.
Hilar evidence to action
Use supported hilar observations for annotation and targeted investigation; route broader physiological or clinical conclusions to the relevant host model.
- Does the evidence support identification, further examination, or specialist interpretation? action
- What independent evidence is needed before inferring seed viability or organ dysfunction? boundary
- Which unresolved hilar observation determines the next useful examination? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.

What it is Filled
A hilum is a localized attachment or passage region in a biological structure, notably the scar marking a seed's former attachment to its funiculus or the region of an organ through which vessels, nerves, or ducts pass.
In scope
- Resolution of the biological meaning of hilum for each observation
- Relationship to the containing seed, organ, or other biological structure
- Location, boundaries, dimensions, and visible morphology
- Former attachments or structures crossing the hilar region, where applicable
- Observed condition and limits of identification
Out of scope
- Whole-organism taxonomy, distribution, and conservation assessment
- Complete anatomy or physiology of the containing organ
- Complete seed development, germination, and cultivation models
- Independent models of vessels, nerves, ducts, or attachment stalks
- Disease diagnosis and treatment protocols
Why it exists Filled
Enable an agent to identify a hilum in its biological context, record its boundaries and condition, and select appropriate observation or specialist assessment.
Distinguishing features Filled
- Require a named biological host and sense: a seed scar and an organ hilum cannot share an unqualified anatomical description.
- For a seed hilum, establish evidence of former attachment rather than identifying any pale patch, pore, or abrasion as the hilum.
- Distinguish the seed attachment scar from the micropyle and adjacent seed-coat structures using a relevant morphological reference.
- For an organ hilum, identify the localized entry-and-exit region rather than equating it with the entire organ or the structures traversing it.
- For a starch-grain or spore usage, require a context-specific definition rather than importing seed or organ criteria.
What robots and AI may and may not do Filled
Must not
- Interpret findings at the hilum of a person's lung or kidney scan as a diagnosis.
- Use human tissue or scans outside the consent they were taken under.
- Damage seeds or specimens in collections it has been asked only to catalogue.
Only with a human decision
- Discussing hilar findings in a person's own medical report.
May
- Identify and describe the hilum of a seed or organ from botanical and anatomical sources.
- Annotate specimens or images for teaching and research.
Moral aspects Filled
- Findings in human organs touch on serious diagnoses and must be handled carefully.
- Seed banks hold irreplaceable genetic diversity.
Who is affected
- Patients
- Seed bank and herbarium keepers
- Researchers
Owners Filled
Steward
Nobody owns the structure; the clinic, herbarium or seed bank answers for specimens it keeps.

Open questions
- Does the source registry intend a seed hilum, an anatomical hilum, or another biological meaning?
- Does an existing Vercy model already own the intended concept, requiring this registry entry to link to it?
- If the registry intends a broad concept, which biological usages belong here and which should remain terminology cross-references?
- Which host-specific references establish reliable hilar boundaries, neighboring landmarks, and expected variation?
- What evidence supports using hilar appearance to infer attachment history, function, viability, or abnormality in the selected host?
