Purpose

This document adds a strong warning about recursion in Mass Number fields.

Mass Numbers are holder packets for modeling moves. They can store representation shifts, invariants, thresholds, obstructions, proof engines, Underverse shadows, and surface projections.

Because abstraction itself can become recursive, every Mass Number field that points to another abstraction must also define a reverse-collapse path.

Forward abstraction without reverse collapse is unsafe.

Core warning

WARNING:
Do not allow Mass Number fields to recursively reference other Mass Numbers,
surfaces, adapters, or abstraction layers unless every recursive edge has:

1. a depth bound,
2. a type boundary,
3. a receipt hash,
4. a reverse-collapse target,
5. an Underverse failure packet,
6. a Warden stop condition.

Why this matters

A Mass Number compresses process.

That compression is useful only if it can be unfolded safely.

If a Mass Number field recursively points to another Mass Number field, and that field points back into the first, the system can enter abstraction recursion:

MassNumber
  -> Surface
  -> Adapter
  -> MassNumber
  -> Surface
  -> Adapter
  -> ...

This can look insightful while actually producing unbounded semantic expansion.

The danger is not only infinite recursion.

The danger is ungrounded abstraction that cannot return to a concrete surface, invariant, packet, or test.

Reverse collapse

Every abstraction path must have a reverse-collapse path.

Forward path:

raw object
  -> Mass Number
  -> Surface
  -> higher abstraction

Reverse-collapse path:

higher abstraction
  -> Surface feature
  -> Mass Number field
  -> concrete object / example / invariant / test

If reverse collapse fails, the abstraction remains HOLD and must not be promoted.

Definition

Reverse collapse = the required operation that maps an abstract Mass Number field
back into a finite, inspectable, testable lower-level representation.

Reverse collapse can target:

concrete example
surface feature
invariant
counterexample
packet schema
bounded metric
source artifact
Lean theorem
simulation trace
validation receipt

Unsafe recursion patterns

R1: Surface echo

MassNumber.surface_projection -> Surface.source_mass_number_id -> same MassNumber

Risk:

the surface explains itself by pointing to the Mass Number that created it

Required fix:

surface must expose at least one concrete feature: ridge, hole, seam, basin,
flow line, scar field, rupture, or contour.

R2: Adapter echo

MassNumber.proof_engine -> CognitiveProcessAdapter -> MassNumber.proof_engine

Risk:

the process adapter claims legitimacy by recursively citing its own abstraction

Required fix:

adapter must cite a source artifact, proof structure, code trace, worked example,
or explicit inference label.

R3: Underverse echo

MassNumber.underverse_shadow -> UnderversePacket -> MassNumber.underverse_shadow

Risk:

failure is explained only by more failure language

Required fix:

Underverse packet must record finite residue: class, metric, forbidden tag,
failed representation tag, Warden status, and receipt hash.

R4: Culture/math echo

cultural form -> invariant -> Mass Number -> cultural form

Risk:

interpretation becomes self-confirming

Required fix:

state the invariant that survives transformation and at least one observed
carrier: body, rhythm, text, ritual, institution, symbol, artifact, or rule.

R5: Physics-native echo

physics metaphor -> surface -> Mass Number -> physics metaphor

Risk:

fictional or metaphorical physics is promoted as real physics

Required fix:

label as representation grammar, impossible-event adapter, toy model, or
physical claim. Physical claims require external evidence and SI accounting.

Recursion safety packet

Every recursive Mass Number field must be accompanied by:

RecursionSafetyPacket = {
  field_id,
  recursion_depth,
  max_depth,
  source_type,
  target_type,
  reverse_collapse_target,
  invariant_anchor,
  surface_anchor,
  underverse_failure_class,
  warden_stop_condition,
  receipt_hash
}

Hot-path numeric values must use fixed-point or integer-coded fields.

Depth policy

Default depth policy:

max_depth = 3

Recommended interpretation:

Depth 0:
  concrete object / source artifact

Depth 1:
  Mass Number packet

Depth 2:
  Surface projection

Depth 3:
  higher abstraction / cross-domain adapter

Anything beyond depth 3 requires explicit Warden approval.

Reverse-collapse test

A Mass Number recursion passes only if the system can answer:

1. What did this abstraction come from?
2. What surface feature does it render as?
3. What invariant does it preserve?
4. What example or source artifact anchors it?
5. What would falsify or break it?
6. What Underverse packet is emitted if reverse collapse fails?
7. What stop condition prevents unbounded recursion?

If any answer is missing, do not promote.

Warden rule

if MassNumberField.references_abstraction == true
and reverse_collapse_target == null:
  emit UnderversePacket.recursive_abstraction_without_ground
  block promotion

if recursion_depth > max_depth:
  emit UnderversePacket.recursion_depth_exceeded
  quarantine field

if field resolves only to itself:
  emit UnderversePacket.self_referential_echo
  require concrete surface anchor

Surface rule

Every recursive abstraction must eventually land on a surface.

No surface, no promotion.

Valid surface anchors include:

ridge
hole
wall
seam
basin
flow line
scar field
contour
rupture
NaN tear
threshold
forbidden region

Underverse rule

If reverse collapse fails, do not leave the abstraction inside the active manifold.

failed reverse collapse
  -> Underverse packet
  -> Warden review
  -> quarantine / snip / downgrade

Compact doctrine

Mass Numbers may recurse, but recursion must be bounded, typed, receipted, and
reversible. Every abstraction must support reverse collapse back into a concrete
surface feature, invariant, source artifact, packet, or test. If the abstraction
cannot reverse-collapse, it becomes an Underverse packet rather than an active
field.
