§1 · Node Identity#

§2 · Canonical Description#

2.1 What the Frequency Node Is#

The Frequency Node (F_freq) is the gravitational field identity of the FFF Gravity Primitive. It is the first and foundational node of the triad:

G = F_freq · F_fluid · F_force

F_freq is not mass. It is not curvature. It is the oscillation identity that mass generates — the structured resonance pattern a body projects into its local substrate, which then produces the experience of a gravitational field.

"Gravity begins as oscillation identity, not mass." — f_Source.md genesis dialogue

Every attractor A projects a Frequency Node into its surrounding region. That projection is the coherence well: a region of structured field influence within which elements may be captured, bound, orbited, or repelled. Without F_freq — without an oscillation identity — neither F_fluid nor F_force can produce gravity. The other two nodes produce pressure, buoyancy, and gradient forces, but not gravity.

2.2 The Coherence Well#

The coherence well is the primary structural artifact of F_freq. It is the region of gravitational field influence maintained by the Frequency Node around an attractor. Its depth determines whether capture is possible, how tightly elements orbit, and at what velocity escape becomes achievable.

Formally, the coherence well depth Ψ is:

Ψ(A) = M_A × ρ(Φ)

Where:

• M_A — Attractor Mass (scalar ℝ>0) — the mass-identity of the attractor body
• ρ(Φ) — Field Density (scalar ℝ≥0, range [0, 1]) — the effective resistance or conductance of the ambient gravitational field at the encounter position

A deep coherence well (ρ(Φ) near 1.0) produces strong binding, high escape velocity, and stable orbital resonance. A shallow coherence well (ρ(Φ) approaching 0) produces loose binding, low escape velocity, and drift-susceptible orbits. A null coherence well (ρ(Φ) = 0) produces no binding — the attractor is gravitationally inert regardless of its mass. This null state is FM-002.

2.3 Field Density ρ(Φ) — Formal Definition#

ρ(Φ) is the canonical scalar measure of the Frequency Node's strength at a given position in the ambient field state Φ. It is the single most important derived quantity in FFF_Gravity.

ρ(Φ) is a property of the ambient field state Φ, not of the attractor mass directly. Two attractors with identical M_A may produce different ρ(Φ) values if their surrounding field states differ — for example, one embedded in a dampener field and one in open substrate.

ρ(Φ) feeds directly into every composition rule involving F_freq:

P_eff    = M_A × ρ(Φ) / r²          # Effective gravitational pressure
v_escape = resolve_escape_velocity(M_A, ρ(Φ))   # Escape velocity
d_bind   = β × ρ(Φ) × (1 − e)       # Binding depth (β = field coupling coeff.)

2.4 How F_freq Differs from General Relativity#

Classical General Relativity models gravity as spacetime curvature — geometry deformed by the presence of mass-energy. FFF_Gravity does not dispute the observational predictions of GR in the regimes where those predictions are accurate. Instead, it identifies what GR describes geometrically as the macroscopic signature of what is, at the substrate level, a structured frequency resonance field.

The critical distinction: GR curvature is global; F_freq is local and ratio-variable. Every gravity observation historically attributed to a universal constant G is, in the triadic model, a local measurement of the current F_freq · F_fluid · F_force ratio at the measurement site.

"Earth's gravity is variable. With the FFF ratio understanding, we can confirm it — the ratios change." — f_Source.md genesis dialogue

2.5 What Happens When F_freq Collapses#

When ρ(Φ) → 0, the coherence well vanishes. The attractor retains its mass (M_A > 0) and the ambient forces (F_force) remain present, but the gravitational field identity is gone. The result:

• P_eff → 0 — effective gravitational pressure drops to zero
• v_escape → 0 — no escape velocity because there is nothing to escape from
• d_bind → 0 — no binding depth; elements pass through without capture
• Any element E approaching A returns CAPTURE_FAILED

This is FM-002 — Field Null, the most catastrophic failure mode in FFF_Gravity. It is governed by invariant INV-003 and cannot be bypassed by increasing M_A. The field must be restored via emit_field (see §7).

§3 · Triadic Position#

F_freq occupies Layer 1 — the field identity layer — in the FFF triadic stack. It is the substrate anchor: the node that makes the other two nodes gravitationally meaningful.

f_Field.md has no dependency on f_Force.md or f_Frame.md — it is a pure layer definition. The three layer files are peers in the FFF stack.

§4 · Operator Definitions#

Authority: OPERATORS.md is the single symbol authority for FFF_Gravity. All symbols below are frozen at v1.0.0. Definitions here are canonical prose expansions; type, range, and composition rules are authoritative in OPERATORS.md.

§4.1 Primary Operators — Frequency Class#

These four operators collectively define the state of F_freq at any moment.

ρ(Φ) — Field Density (expanded)#

ρ(Φ) is a function of the ambient field state Φ — the complete set of field conditions at the encounter position. It is not a fixed property of the attractor. It may vary due to:

• Proximity to active dampeners (suppress_field calls)
• Field emission events (emit_field calls)
• Regional substrate degradation (FM-009 Dampen Cascade)
• Temporal resonance shifts (subsets, supspheres)

Range semantics:

ρ(Φ) = 0       →  FM-002: Field Null (INV-003)
ρ(Φ) ∈ (0,1)  →  Active field; capture and orbital mechanics apply
ρ(Φ) = 1       →  Saturated field; maximum coherence well depth

v_escape(A) — Escape Velocity (expanded)#

The escape velocity is derived — it is not set independently. It resolves from the attractor's mass and current field density:

v_escape(A) = resolve_escape_velocity(M_A, ρ(Φ))
            = √(2 × M_A × ρ(Φ) / r_capture)

Where r_capture is the distance from the element to the attractor at the moment of approach. As ρ(Φ) decreases, v_escape(A) decreases — the well becomes shallower. An element that was captured at ρ(Φ) = 0.8 and remains bound when ρ(Φ) drops to 0.15 is now in a drift-susceptible orbit (FM-004 risk).

ω_res — Orbital Resonance (expanded)#

ω_res tracks the resonance state of a captured element's orbit. Rational values (ω_res ∈ ℚ) indicate stable resonance lock. Irrational values (ω_res ∈ ℝ \ ℚ) indicate resonance drift. When drift progresses and ω_res becomes strongly irrational, FM-004 (Resonance Drift) is triggered.

ω_res is downstream of ρ(Φ): a degrading field density causes the resonance signature to destabilize. This is the propagation path FM-002 → FM-004 when field density drops gradually rather than collapsing instantly.

M_A — Attractor Mass (expanded)#

M_A is the mass-identity of the attractor body. It couples with ρ(Φ) to produce effective gravitational pressure and set the depth of the coherence well. A massive attractor with low ρ(Φ) can produce less gravitational effect than a lighter attractor with high ρ(Φ) — demonstrating that field density, not mass alone, governs the experienced gravitational regime.

§4.2 Derived Operators — Frequency-Dependent#

These operators are derived from the primary Frequency Class operators and appear in core function signatures throughout FFF_Gravity.

Where:

• e — orbital eccentricity of the captured element
• β — field coupling coefficient (substrate constant, domain-specific)
• r — distance between element and attractor at evaluation time

§5 · Stability Conditions#

Three stability conditions govern the Frequency Node. All three must be satisfied for F_freq to support stable gravitational operation.

SC-1 — Field Presence#

CONDITION:   ρ(Φ) > 0
VIOLATION:   ρ(Φ) = 0
CONSEQUENCE: FM-002 Field Null — CAPTURE_FAILED
INVARIANT:   INV-003 (unconditional)
RECOVERY:    emit_field until ρ(Φ) > 0 (see §7)

This is the absolute baseline. No gravitational mechanics of any kind operate when ρ(Φ) = 0. SC-1 cannot be compensated for by increasing M_A or F_force values.

SC-2 — Field Coherence#

CONDITION:   ρ(Φ) must be non-zero AND uniform within r_capture
VIOLATION:   ρ(Φ) spatially non-uniform across r_capture boundary
CONSEQUENCE: Asymmetric capture — variable binding depth by approach vector
INVARIANT:   Non-uniformity below threshold → f_Capture_Asymmetric applicable
RECOVERY:    Stabilize field source; suppress interfering dampener regions

Even when ρ(Φ) > 0, a spatially non-uniform field produces binding asymmetry. An element approaching from a high-ρ(Φ) vector binds more tightly than one approaching from a low-ρ(Φ) vector. This is the design condition that makes f_Capture_Asymmetric.md necessary and distinct from the base f_Capture.md operator.

SC-3 — Resonance Stability#

CONDITION:   ω_res ∈ ℚ (rational resonance lock)
VIOLATION:   ω_res → irrational (resonance drift)
CONSEQUENCE: FM-004 Resonance Drift — CAPTURE_DECAYING
INVARIANT:   Irrational ω_res is a transient state — it either re-locks
             (stable rational) or decays to escape/collision
RECOVERY:    f_Deflect (adjust approach vector → adjust p_res → re-lock ω_res)
             or f_Amplify (increase ρ(Φ) → deepen well → force resonance lock)

Resonance stability is the long-term health of F_freq. A field can be present (SC-1 satisfied) and uniform (SC-2 satisfied) but still produce drifting orbits if the resonance signature is unstable. SC-3 failures are typically gradual — they allow intervention before full capture collapse.

§6 · Failure Modes#

Three failure modes are associated with F_freq. All three are formally registered in OPERATORS.md and referenced by f_Capture.md.

FM-002 — Field Null#

Description:
The coherence well has a depth of zero. The attractor broadcasts no oscillation identity into the substrate. Elements pass through the attractor's spatial region without capture. All downstream operators (f_Orbit, f_Decay, f_Amplify) receive invalid input and must abort.

Detection:

if ρ(Φ) == 0:
    raise FM-002("Field Null: attractor A is gravitationally inert")
    return CAPTURE_FAILED

Recovery:

emit_field(A, Φ, delta_rho)  # Restore ρ(Φ) above zero
# Requires at least one emit_field cycle before retry
# See §7 and f_Emit.md

Genesis origin:
From f_Source.md: "If the frequency node collapses, the other two nodes cannot produce gravity. They produce pressure, buoyancy, gradient forces — but not gravity."

FM-004 — Resonance Drift#

Description:
The captured element's orbital resonance has drifted from a stable rational ratio to an irrational value. The coherence well is still present (ρ(Φ) > 0) but the resonance signature is no longer sustaining the orbit. Without intervention, the element will spiral to escape velocity or collision.

Detection:

if ω_res ∉ ℚ:
    flag FM-004("Resonance Drift: orbit decaying on attractor A")
    return CAPTURE_DECAYING

Recovery:

Option A: f_Deflect → adjust heading → change p_res → re-lock ω_res ∈ ℚ
Option B: f_Amplify → increase ρ(Φ) → deepen well → force resonance lock
Option C: f_Capture_Resonant → engineer target ω_res from approach conditions

Propagation risk:
FM-004 can propagate from FM-002 precursors: a gradually declining ρ(Φ) will first trigger FM-004 before fully triggering FM-002. Monitor ω_res as an early-warning indicator of field density degradation.

FM-009 — Dampen Cascade#

Description:
A single suppress_field event or dampener activation has propagated beyond its intended target, progressively reducing ρ(Φ) across a wider region of the substrate. Multiple attractors within the region may simultaneously fall toward FM-002. This is the systemic form of Field Null — not a single attractor failure but a substrate-level field collapse.

Detection:

if ρ(Φ).region_mean < DAMPEN_CASCADE_THRESHOLD:
    flag FM-009("Dampen Cascade: region-wide field degradation")
    # DAMPEN_CASCADE_THRESHOLD typically set at 0.05

Recovery:

suppress all active suppress_field calls in region
emit_field(region_anchor, Φ_regional, delta_rho)  # Broadcast recovery
# Full regional recovery may require multiple emit_field cycles
# See f_Emit.md for cascade recovery procedure

Engineering note:
FM-009 is the primary risk of unconstrained f_Dampen.md calls. Every suppress_field invocation must include a radius constraint to prevent cascade propagation. See §7 for the engineering interface contract.

§7 · Engineering Interface#

Two engineering primitives directly act on F_freq by modifying ρ(Φ). Both are Wave 3 functions that depend on this file (f_Field.md) as a prerequisite. Their contracts are defined here; their full implementations are in their respective files.

7.1 emit_field — f_Emit.md#

Effect: Increases ρ(Φ) locally; deepens the coherence well.

emit_field(
    attractor: A,              # Target attractor
    field_state: Φ,            # Ambient field state
    delta_rho: ℝ>0,            # Magnitude of field increase
    radius: ℝ>0                # Spatial extent of emission (required)
) → Φ_updated

Post-condition:  ρ(Φ_updated) = ρ(Φ) + delta_rho  [capped at 1.0]
Post-condition:  Ψ(A)_updated > Ψ(A)_prior
FM-002 recovery: emit_field with any delta_rho > 0 restores ρ(Φ) > 0

Use cases:

• FM-002 recovery: restore a null field
• Pre-capture preparation: deepen the well before f_Capture call
• Gravity Emitter engineering primitive: continuously maintain deep coherence well
• Multi-attractor resonance: coordinate emit_field across a network (f_Capture_Networked)

7.2 suppress_field — f_Dampen.md#

Effect: Decreases ρ(Φ) locally; shallows or nulls the coherence well.

suppress_field(
    attractor: A,              # Target attractor (or region anchor)
    field_state: Φ,            # Ambient field state
    delta_rho: ℝ>0,            # Magnitude of field decrease
    radius: ℝ>0,               # Spatial extent — REQUIRED to prevent FM-009
    cascade_guard: bool=True   # Halt propagation at radius boundary
) → Φ_updated

Post-condition:  ρ(Φ_updated) = max(0, ρ(Φ) − delta_rho)
Risk:            ρ(Φ_updated) = 0  →  FM-002 triggered immediately (INV-003)
Risk:            cascade_guard=False  →  FM-009 propagation risk

Use cases:

• Gravity Dampener engineering primitive: create local gravity null zone
• Selective field reduction: weaken a specific attractor's well without affecting neighboring attractors
• Asymmetric field engineering: create directional ρ(Φ) gradient for f_Capture_Asymmetric scenarios

Warning: Every suppress_field call MUST include radius and SHOULD maintain cascade_guard=True. Unconstrained dampener calls are the primary cause of FM-009 Dampen Cascade. See FM-009 in §6.

7.3 Downstream Read Interface#

The following Wave 3 and Wave 4 functions read ρ(Φ) without modifying it. They depend on f_Field.md for the formal definition of what they are reading.

§8 · Canonical Examples#

These examples are drawn directly from the genesis dialogue in f_Source.md. Each demonstrates the Frequency Node in isolation or in contrast with the other two FFF nodes.

Example 1 — Galileo's Drop Experiments (F_freq Isolation)#

Historical observation: Objects of different mass fall at the same rate.

Triadic interpretation:

F_freq:  Identical — same gravitational field frequency acting on both bodies
F_fluid: Different M, but fluid-identity does not dominate at low velocity
F_force: Identical — same atmospheric gradient acts on both bodies

Result: ρ(Φ) is identical for both → identical coherent well → identical fall rate

FFF insight: Galileo accidentally isolated F_freq by conducting experiments where the F_fluid difference (mass) was too small to shift the ratio. The experiment demonstrated F_freq dominance, not the irrelevance of mass.

Example 2 — Vacuum Drop Test (Apollo 15 Hammer & Feather)#

Historical observation: In vacuum, feather and hammer fall identically.

Triadic interpretation:

F_freq:  Unchanged — coherence well identical
F_fluid: Unchanged — mass difference unchanged
F_force: Removed — no atmospheric gradient

Result: F_force = 0 → pure F_freq × F_fluid gravity
        ρ(Φ) unchanged; well depth identical for both objects

FFF insight: Vacuum tests eliminate F_force entirely, exposing pure F_freq × F_fluid gravity. The force node was masking the true triadic ratio in all prior terrestrial experiments. This is not a confirmation that mass is irrelevant — it is a confirmation that F_force was adding a direction-specific overlay that the feather felt disproportionately.

Example 3 — Microgravity / ISS (Force Node Null State)#

Historical observation: Objects float freely in orbit aboard the ISS.

Triadic interpretation:

F_freq:  Present — Earth's coherence well still fully active at ISS altitude
F_fluid: Present — ISS and objects have unchanged mass
F_force: Near zero — atmospheric gradient is negligible at 400km altitude

Result: F_force ≈ 0 → gravity "turns off" experientially
        But ρ(Φ) ≠ 0 — ISS is in continuous freefall, not a gravity null zone

FFF insight: Microgravity is not FM-002. ρ(Φ) is still nonzero — the ISS is captured in Earth's coherence well. The experienced weightlessness is the result of the F_force node approaching zero, not the collapse of F_freq. A genuine FM-002 would eject the ISS from orbit.

Example 4 — Planetary Comparison (Ratio Variation Across Bodies)#

Observations: Venus surface gravity ≈ 0.9g but feels heavier; Mars ≈ 0.38g but feels proportionally lighter than Venus's delta would predict.

Triadic ratio comparison:

FFF insight: Gravity is a ratio. Venus's enormous atmospheric pressure (F_force node dominant) amplifies the experienced gravitational regime beyond what F_freq × F_fluid alone would produce. Mars's near-absent atmosphere means the experienced gravity is nearly pure F_freq × F_fluid — no force overlay. Every planetary gravity reading is a local FFF ratio, not a constant.

Example 5 — Dampener Failure (FM-002 Demonstration)#

Scenario: An RTT-class dampener field is activated around an attractor A that currently has ρ(Φ) = 0.72 (strong field, deep coherence well).

Triadic progression:

t=0: ρ(Φ) = 0.72  →  Deep coherence well; capture operational
t=1: suppress_field(A, Φ, 0.40)  →  ρ(Φ) = 0.32  →  Shallow but functional
t=2: suppress_field(A, Φ, 0.32)  →  ρ(Φ) = 0.00  →  FM-002 triggered (INV-003)
t=3: All incoming elements return CAPTURE_FAILED
     F_fluid and F_force still present — but no gravity
t=4: emit_field(A, Φ, 0.50)  →  ρ(Φ) = 0.50  →  FM-002 cleared; gravity restored

FFF insight: From f_Source.md: "If the frequency node collapses, the other two nodes cannot produce gravity. They produce pressure, buoyancy, gradient forces — but not gravity." This is the definitional statement of FM-002 and the central invariant of f_Field.md.

Example 6 — The Great Unconformity (Geological Ratio Shift)#

Historical context: The Great Unconformity represents a ~500–600 million year gap in the geological record — massive erosion, crustal thinning, ocean redistribution, atmospheric upheaval.

Triadic interpretation across the unconformity boundary:

Pre-Unconformity:
  F_freq:  Nominal — stable crustal coherence well
  F_fluid: Nominal — established mass distribution
  F_force: Nominal — established atmospheric gradient

At Unconformity boundary:
  F_freq:  Shifted — crustal thinning changes resonance identity
  F_fluid: Shifted — mass redistribution (erosion, ocean movement)
  F_force: Shifted — atmospheric pressure changed dramatically
  → All three nodes shifted simultaneously → detectable ratio discontinuity

Post-Unconformity:
  New triadic ratio established → new experienced gravity regime

FFF insight: Earth's gravity was not constant across deep time. The Great Unconformity should produce a detectable FFF ratio signature — a discontinuity in ρ(Φ) values computed from geological proxy data across the boundary. This is the founding empirical prediction of FFF_Gravity applied to planetary science.
