Compo 19.00 — Hierarchy signal model

Signal identity before contribution

00 / contract

explicit subject eligibility + explicit owner-qualified signal binding + exact evidence snapshot → HierarchySignalObservation explicit signal↔signal dependency declaration → HierarchySignalDependency 19.00 stops here. NO contribution normalization NO channel weights NO correlation coefficient NO composite rank NO hierarchy confidence NO MetricResult

Root signal layer only

01 / ownership

OWNS

19.00

Explicit signal-subject eligibility, signal kinds, owner-qualified bindings, evidence/observation identity, dependency declarations, signal-set policy and immutable HierarchySignalSystemSeed.

DOES NOT OWN

Downstream + foreign

19.01–19.03 contribution math; 19.04 correlation-aware aggregation, composite rank/confidence; Topic18 subordination; Compo13 dominance; Compo4 visual mass; final-layout ranking.

Boundary: Topic19 describes observed multi-signal visual hierarchy. It may compare later with Topic18 declared hierarchy, but it cannot rewrite Topic18 roles or relations.

Subjects are explicit

02 / subject set

HierarchySignalSubject {
  hierarchySignalSubjectRef,
  scopeRef,
  subjectRef,
  eligibilityResolutionRef,
  status,
  mutationAllowed: false
}

HierarchySignalSubjectSetPolicy {
  selectionMode: EXPLICIT_ELIGIBLE_SUBJECTS_ONLY,
  maxSubjects: 1..4096,
  overflowPolicy: N_A_NO_TRUNCATION,
  fullCartesianProductAllowed: false
}

No appearance-based admission.

Элемент не становится Topic19 subject автоматически из-за размера, центра кадра, контраста, z-index, Topic18 PRIMARY role или Compo13 dominance. Eligibility должна быть объявлена явно.

Six signal kinds, zero implicit priority

03 / taxonomy

Signal	19.00 stores	19.00 does not infer
SIZE	owner-qualified size-related payload	visual mass, scale class, contribution strength
TONE	tone/luminance-related payload	contrast importance or target desirability
COLOR	color-related payload	salience, harmony or dominance
ISOLATION	isolation/separation payload	focality or whitespace quality
POSITION	position-related payload	center/top = important
SEMANTIC_PRIORITY	explicit semantic-priority payload	Topic18 role or semantic truth from appearance

No taxonomy order: SIZE before TONE in the enum is serialization only. It is not a weight, precedence rule or default ranking.

Bindings preserve foreign ownership

04 / channel contract

HierarchySignalBinding {
  signalKind,
  representationKind:
    SCALAR | VECTOR | CATEGORY | ORDINAL | BOOLEAN | OWNER_DEFINED,
  signalChannelRef,
  measurementMethodRef,
  unitRef,
  referenceFrameRef,
  measurementContextRef,
  signalSourceOwnerRef,
  bindingSourceRef,
  bindingSourceOwnerRef,
  provenance,
  mutationAllowed: false
}

same number + different owner/unit/frame/context ≠ same signal binding ≠ measurement owner transfer ≠ contribution definition ≠ normalization policy

Evidence stays evidence

05 / observation

VALID

Exact lineage

Subject, binding, snapshot, representation and owner-qualified source all match. Equal duplicate payloads may resolve to one observation.

NO GUESS

Conflict / missing

Conflicting compatible evidence → N_A. Missing evidence → N_A. Confidence cannot silently choose a winner.

HierarchySignalObservation {
  hierarchySignalSubjectRef,
  hierarchySignalBindingRef,
  signalKind,
  evidenceRefs[],
  observationPayloadRef,

  contributionRef: null,
  normalizedContribution: null,
  rankContribution: null,

  status,
  reasonCode,
  mutationAllowed: false
}

Confidence firewall: evidence confidence is diagnostic. It is not the future composite hierarchy confidence.

Declare dependency, do not estimate it

06 / anti-double-counting input

Kind	Direction	Meaning
DERIVED_FROM	directed	Target signal explicitly derives from a source signal/evidence chain.
SHARED_RAW_EVIDENCE	symmetric	Two observations reuse raw evidence lineage.
SHARED_MEASUREMENT_BASIS	symmetric	Two signals depend on the same measurement basis/transform.
OWNER_DECLARED_CORRELATION	symmetric	Source owner explicitly declares correlation; 19.00 stores no coefficient.
AUTHOR_DECLARED_DEPENDENCY	explicit	Project/brief dependency declaration with no numeric strength.

dependencyStrength = null correlationCoefficient = null deduplicationWeight = null 19.04 owns numeric correlation handling. 19.00 only preserves dependency topology + lineage.

Explicit set, no channel explosion

07 / bounded registry

SIGNALS

Explicit only

Only explicit observations enter HierarchySignalSet.

DEPENDENCIES

Explicit only

No automatic correlation discovery or dependency guessing.

NO CARTESIAN

Subject × channel

A missing channel is not synthesized for every subject.

HierarchySignalSystemSeed {
  hierarchySignalSubjectSetRef,
  hierarchySignalSetRef,

  sizeContributionAttachmentRef: null,
  toneColorContributionAttachmentRef: null,
  isolationPositionSemanticContributionAttachmentRef: null,
  correlationAwareHierarchyAttachmentRef: null,
  compositeRankRef: null,
  confidenceRef: null,
  metricResultRefs: [],

  mutationAllowed: false
}

N_A, INVALID and zero stay different

08 / status

Case	Status	Meaning
Missing subject eligibility	N_A	Cannot include subject without guessing.
Eligibility conflict	N_A	Explicit sources disagree.
Missing signal evidence	N_A	Signal observation is unavailable, not zero.
Conflicting signal evidence	N_A	No averaging or confidence winner in 19.00.
Representation mismatch	INVALID	Payload violates its explicit binding.
Dependency self-edge	INVALID	Dependency relation is structurally invalid.
Legitimate scalar payload 0	OK	Zero may be a valid raw observation if binding semantics allow it.

Contribution owners remain downstream

09 / owners

19.00	Signal subjects, bindings, observations, dependency declarations, signal-set identity.
19.01	SIZE contribution.
19.02	TONE / COLOR contribution.
19.03	ISOLATION / POSITION / SEMANTIC_PRIORITY contribution.
19.04	Correlation-aware aggregation, anti-double-counting, composite rank, confidence and tests.
Topic18	Declared generic hierarchy / subordination remains foreign-owned.
Compo13	Dominance / focal ranking remains foreign-owned.
Compo4	Visual mass remains foreign-owned.

No hidden rank in the root layer

10 / firewalls

HierarchySignalObservation != contribution score signal evidence confidence != hierarchy confidence dependency declaration != correlation coefficient dependency declaration != penalty missing signal != zero contribution Topic18 declared hierarchy != Topic19 observed visual hierarchy SEMANTIC_PRIORITY signal != Topic18 PRIMARY role SIZE signal != Topic16 scale ratio/class TONE/COLOR signal != dominance score ISOLATION/POSITION signal != focal ranking 19.00 owns_metrics = [] 19.00 independent numeric votes = 0 19.00 composite rank = null

19.00 regression suite

12 / deterministic tests

Tests cover explicit eligibility, six signal kinds, representation validation, exact owner/binding lineage, evidence conflict preservation, explicit dependency orientation, symmetric dependency identity, no auto-correlation, bounded signal sets, immutable root seed, zero metrics and Topic18/19.01–19.04 ownership firewalls.

Tests not run yet.
