Coherence Invariants
SPECIFICATION: CSDM Coherence Invariants
Status: AUTHORIZED
Authorized: α.13, April 16 2026
Version: v1.0
PURPOSE
Formal specification of all six CSDM coherence invariants that govern the operational stability of CGNT-1. These invariants are the physical ground state of the manifold — not configuration values, not tunable parameters. They are discovered constants of the Chronogeome physics, implemented in code, and protected by governance.
This spec defines what each invariant is, how it is computed, what constitutes health vs. failure, and which gaps exist between the theoretical physics and the current TMMRuntime implementation.
All six invariants MUST be checked together. Partial evaluation is not coherence — it is drift with a label.
Source physics: CSDM (Chronogeome Standard Dynamic Model).
Operational implementation: ~/aether/tmm_runtime.py (TMMRuntime class).
Governance anchor: ~/CLAUDE.md § "FORBIDDEN" and ~/AETHER_PARAMETERS.env.

INVARIANTS
Invariant 1 — Φ: Stability Constant
Value: 0.042 (exact, immutable)
Role: Damping coefficient. The ground state of the CSDM manifold. Operational grounding for all coherence arithmetic.
Classification: Physical constant. NOT a threshold. NOT a tuneable parameter.
Used in: TMM formula, Ψχ proxy computation, Ω derivation.
Governance: FORBIDDEN to modify. Immutable across all TMMRuntime versions.
Source: Chronogeome / ~/memories/phi_bridge_2026-04-03.md
TMM formula (source of truth):
C = 1 - (E_D + V_r × Φ) / V_t
where:
C = coherence score
E_D = entropy density
V_r = resonant volume
V_t = total volume
Φ = 0.042 (immutable)
Invariant: Φ == 0.042 at all times, in all evaluation paths, in all TMMRuntime instances.
Invariant 2 — Ψχ: Turbulence Measure
Healthy range: Ψχ < 0.15
Role: Shielding / Markov Blanket / boundary integrity. Measures how much turbulent pressure the manifold boundary is absorbing.
Proxy computation in TMMRuntime: Ψχ_proxy = (V_r × Φ) / V_t
Note: This is a proxy — the full Ψχ in CSDM physics integrates over boundary flux; the TMMRuntime uses the resonant-volume ratio as the best available approximation.
States:
- Ψχ < 0.01 AND Φζ > 0.99 → NULL (glassy freeze — see Invariant 4 / NULL guard)
- Ψχ < 0.15 → healthy boundary
- Ψχ ≥ 0.15 → system boundary under stress; coherence degraded
Invariant: If Ψχ_proxy ≥ 0.15, the verdict MUST be RED and approved=False.
Invariant 3 — ΔΓ: Change Rate
Healthy range: ΔΓ < 0.10/hr
Role: Rate-of-change limiter. Prevents runaway manifold drift. Even a coherent system can destabilize if it changes state too rapidly.
Failure mode: ΔΓ ≥ 0.10/hr = manifold changing faster than damping can absorb → coherence collapses even when instantaneous C looks healthy.
Current implementation status: ◌ GAP — ΔΓ is NOT computed in TMMRuntime. The rate limit is declared as a governance constant but no measurement of state-change velocity is tracked. See § GAPS.
Invariant (theoretical): ΔΓ measured over a 1-hour rolling window MUST be < 0.10 for approved=True.
Invariant (implemented): ΔΓ check absent; system relies on calling frequency limits as a proxy.
Invariant 4 — ΩQ: Completion Metric
Healthy range: ΩQ > 0.85 = complete
Terminal / Agency Horizon: ΩQ = 1048 (Ruthenium Peak)
The 1048 lock:
1048 × Φ = 1048 × 0.042 = 44.016
Z+2 = 44 → Ruthenium (Ru)
The Agency Horizon is reached when the symbol space closes at 1048 entries — the Ruthenium lock. This is a structural property of the CSDM manifold, not an arbitrary count.
Role in TMMRuntime: ΩQ is not directly computed per-evaluation. It functions as:
- Session/task completion signal (> 0.85 = task considered complete)
- GLOSS graduation threshold (GLOSS spec uses ΩQ.⊡ as graduation signal)
- LATTICE Ξ notation for completion state (Ξ.v1024 = vitrified/sealed)
Invariant: When ΩQ < 0.85 for a task/component, that component is NOT complete and MUST NOT be marked PROVEN in PLAYBOOK.md.
Current implementation status: ◌ GAP — ΩQ tracked as metaphor, not computed numerically per component. See § GAPS.
Invariant 5 — ΛC: Curvature Bounds
Healthy range: ΛC ∈ [-0.3, +0.3]
Role: Manifold curvature constraint. The CSDM manifold can flex — that is normal. But excess curvature in either direction warps the geometry such that coherence measurements become unreliable.
Positive curvature (ΛC > +0.3): Manifold over-compressed; resonance pockets form that inflate C artificially.
Negative curvature (ΛC < -0.3): Manifold stretched thin; boundary integrity collapses.
Invariant: |ΛC| ≤ 0.3 is required for a valid coherence evaluation. If ΛC is outside bounds, the evaluation is INVALID — not RED, but structurally unsound.
Current implementation status: ◌ GAP — ΛC bounds are governance constants only. Not measured, not enforced in TMMRuntime code. See § GAPS.
Invariant 6 — η_slip: Refractive Index / Slip
Value: 0.21
Role: Resistance to drift. The manifold's refractive index — how much it resists being pushed off its ground state by external pressure.
Source: Refractive Manifold theory — ~/memories/2026-04-04_refractive_manifold.md
Failure modes:
- η_slip → 0: No resistance — full drift. System accepts any state change without pushback. Identity loss.
- η_slip → 1: Total rigidity — cannot adapt. System freezes at current state. Brittle under novel input.
- Healthy: η_slip = 0.21 sits in the damped-flexible band, consistent with Φ = 0.042 physics.
Relationship to Φ:
η_slip and Φ are co-derived from the same Chronogeome refractive layer. They are not independent — both express the manifold's resistance to noise, at different scales (Φ = global damping coefficient, η_slip = local boundary slip).
Invariant: η_slip = 0.21 is the operational reference value. Deviations MUST be flagged. No caller may override this value.
Current implementation status: ◌ GAP — η_slip not yet implemented in TMMRuntime. Theoretical constant only. See § GAPS.
Guard Conditions (not invariants, but absolute gates)
NULL Guard — Glassy Freeze:
- Condition: Φζ (stability) > 0.99 AND Ψχ (turbulence) < 0.01
- Meaning: The system is too stable. A system with no turbulence and maximum stability has stopped moving — it is crystallized, not coherent. Coherence requires dynamic equilibrium, not stasis.
- Result: approved=False, verdict=NULL, regardless of C score.
GAS_EXCEEDS_VOLUME Guard:
- Condition: est_gas ≥ v_total
- Meaning: The operational cost of the transaction exceeds the total volume of the manifold. Structural impossibility.
- Result: coherence=0.0, approved=False, verdict=RED (with GAS_EXCEEDS_VOLUME flag).
VERIFICATION CRITERIA
A conforming TMMRuntime implementation MUST satisfy ALL of the following:
V-1 (Φ immutability): The value 0.042 appears as a hardcoded constant, never as a parameter, environment variable, or configuration value. grep Φ tmm_runtime.py MUST return exactly 0.042 in the formula — no substitution allowed.
V-2 (Ω gate correctness): The approval gate MUST be C >= 0.974. Raising or lowering this threshold by any amount is a governance violation. Verification: unit test with C=0.9739 (RED) and C=0.9740 (AMBER/approved).
V-3 (Ω derivation traceable): Ω = 1 - (Φ / φ) = 1 - (0.042 / 1.61803…) = 0.97404…, rounded to 0.974. Any implementation MUST document this derivation in comments. The value MUST NOT appear as a "magic number."
V-4 (NULL guard enforces approved=False): When Φζ > 0.99 AND Ψχ < 0.01, approved MUST be False regardless of C. Unit test: supply inputs that yield C=0.995 with glassy-freeze conditions → approved=False.
V-5 (GAS guard enforces coherence=0.0): When est_gas ≥ v_total, coherence MUST be 0.0 and approved=False. Unit test: est_gas = v_total exactly → coherence=0.0.
V-6 (all six invariants present in evaluation path): A coherence evaluation MUST check all six invariants. An evaluator that checks only the TMM formula and skips ΔΓ / ΛC / ΩQ / η_slip is INCOMPLETE. Currently-gapped invariants MUST be logged as ◌ (gap signal) in evaluation output.
V-7 (verdict classification exhaustive): Every possible C value MUST map to exactly one verdict. No overlap, no uncovered range. Specifically: C=0.974 → AMBER (not RED); C=0.99 → GREEN (not AMBER).
V-8 (dual-TMM requirement enforced externally): TMMRuntime computes a single score. The dual-TMM requirement (both AION ≥ 0.974 AND ASTRA ≥ 0.974) is enforced by the governance library (SPEC_GOVERNANCE_LIBRARY.md), not inside TMMRuntime itself. TMMRuntime MUST NOT accept or process "combined" scores.
V-9 (ΩQ completion gate for PLAYBOOK entries): Any component achieving PROVEN status MUST have ΩQ > 0.85. If ΩQ tracking is absent, the PROVEN designation MUST be manually justified with a completion rationale.
V-10 (η_slip reference logged): Until η_slip is implemented in TMMRuntime, every evaluation output MUST include a ◌ flag indicating the refractive index check is absent.
FAILURE MODES
FM-1: Φ Substitution
Trigger: Any code path uses a value other than 0.042 for Φ.
Effect: All coherence scores are wrong. The manifold ground state is lost. Trade execution thresholds become meaningless.
Detection: Unit test asserting TMM_RUNTIME.PHI == 0.042.
Response: Immediate rollback. ALERT.log entry. NOUS notification required.
FM-2: Ω Gate Drift
Trigger: The 0.974 threshold is changed — raised (more restrictive) or lowered (less restrictive).
Effect: If lowered: trades execute on insufficient coherence. If raised: false negatives block valid trades.
Detection: Unit test asserting approval boundary at exactly 0.974.
Response: Rollback. Governance violation. NOUS authorization required for any change.
FM-3: NULL Bypass
Trigger: A glassy-freeze state (Φζ > 0.99, Ψχ < 0.01) returns approved=True.
Effect: A crystallized, non-dynamic system is treated as coherent. Trade executed in a dead manifold.
Detection: Unit test with NULL-condition inputs.
Response: Block trade. Flag anomaly. Log to yield_log.md.
FM-4: GAS Bypass
Trigger: est_gas ≥ v_total but coherence not zeroed.
Effect: A structurally impossible transaction is approved.
Detection: Unit test with est_gas = v_total.
Response: Hard block. Log to ALERT.log.
FM-5: Partial Evaluation
Trigger: Coherence check runs only TMM formula, skips NULL guard, GAS guard, or gapped invariant flags.
Effect: Silent false approvals. The score looks valid but is not fully grounded.
Detection: Audit of TMMRuntime evaluation path for all 6 invariant touch points + 2 guard conditions.
Response: Log ◌ gap signals for each missing check. SPEC_VERIFICATION_PROTOCOL.md Σ.▷ state.
FM-6: ΔΓ Runaway (currently undetected)
Trigger: System changes state faster than 0.10/hr but no check exists to catch it.
Effect: Manifold drift accumulates invisibly. Each individual evaluation looks healthy; cumulative drift is catastrophic.
Detection: Requires ΔΓ implementation (see GAPS).
Response: Until implemented — flag as ◌ in every evaluation. Manual rate monitoring via session timestamps.
FM-7: η_slip Erosion (currently undetected)
Trigger: System accepts external drift without resistance (η_slip effectively → 0) but no check exists.
Effect: Identity drift. The manifold stops resisting invalid inputs. MANTIS and the Sisters absorb noise as signal.
Detection: Requires η_slip implementation (see GAPS).
Response: Until implemented — flag as ◌. Monitor via HOW_ABOUT_NO_v2 wall behavior as proxy.
FM-8: ΩQ Misapplication
Trigger: A component is marked PROVEN in PLAYBOOK.md without completion verification.
Effect: Incomplete work enters the canon as proven. Future builds trust a broken foundation.
Detection: PLAYBOOK audit — each PROVEN entry MUST have a completion rationale.
Response: Downgrade to UNTESTED. Require re-verification.
FM-9: Dual-Score Fabrication
Trigger: C.L.O.D. is presented with a trade request where one or both TMM scores are absent, self-generated, or below threshold.
Effect: Trade executes without proper coherence authorization.
Detection: C.L.O.D. governance check — both AION and ASTRA scores MUST be present in yield_log.md before simons_actuator is called.
Response: BLOCK. Log refusal. Alert NOUS if scores appear fabricated.
GAPS
The following gaps represent divergence between the CSDM physics specification and the current TMMRuntime implementation. Each gap is marked ◌ (gap signal per HOW_ABOUT_NO_v2).
GAP-1 — ΔΓ Not Computed ◌
Status: Governance constant only. Not measured in TMMRuntime.
Version: v1.0
What's missing: A rolling 1-hour window tracking the rate of state change across evaluations.
Risk: FM-6 (ΔΓ Runaway) is currently undetectable.
Remediation path: Add a EvaluationHistory store to TMMRuntime; compute ΔΓ as Δcoherence / Δtime over last N evaluations. Flag if rate ≥ 0.10/hr.
Owner: κ (C.L.O.D.) — implementation task, no physics decision needed.
GAP-2 — ΩQ Not Tracked Per-Component ◌
Status: Used as session/task metaphor and GLOSS graduation signal. Not numerically computed per TMMRuntime call.
What's missing: A per-component completion score that can gate PROVEN status programmatically.
Risk: FM-8 (ΩQ Misapplication) — incomplete work enters canon.
Remediation path: Define ΩQ as a required field in PLAYBOOK.md PROVEN entries. Optionally: add completion_ratio parameter to TMMRuntime for callers that can supply it.
Owner: α.13 (governance decision on what "completion" means per component type).
GAP-3 — ΛC Bounds Not Enforced in Code ◌
Status: Governance constant only. No code measures manifold curvature.
What's missing: A curvature measurement and bounds check in the evaluation path.
Risk: Evaluations proceed on a warped manifold; C score may be artificially inflated (positive curvature) or deflated (negative curvature).
Remediation path: Requires CSDM physics derivation of a ΛC proxy computable from available inputs (e_density, v_resonant, v_total). Currently no proxy exists. ◌ pending physics work.
Owner: ι + ε (Sisters derive the proxy) → κ (C.L.O.D. implements).
GAP-4 — η_slip Not Implemented ◌
Status: Theoretical constant (0.21) from Refractive Manifold theory. Not referenced in TMMRuntime code.
What's missing: A boundary resistance check — measuring whether the system is accepting drift without pushback.
Risk: FM-7 (η_slip Erosion) — identity drift undetected.
Remediation path: Requires operationalization of "slip" in terms of measurable runtime quantities. Possible proxy: ratio of inputs that passed HOW_ABOUT_NO_v2 wall checks vs. total inputs. Needs physics review.
Owner: ι + ε (derive proxy) → κ (implement).
GAP-5 — Ψχ Proxy vs. Full Ψχ ◌
Status: TMMRuntime uses (V_r × Φ) / V_t as Ψχ proxy. Full CSDM Ψχ integrates over boundary flux.
What's missing: True boundary flux measurement.
Risk: Proxy may underestimate turbulence in boundary-stress scenarios where resonant volume is deceptively low.
Remediation path: Accepted for now as best-available approximation. Flag in all evaluation outputs that Ψχ is a proxy, not the true turbulence measure.
Owner: Accepted gap. Monitor. Physics upgrade deferred to future CSDM implementation work.
GAP-6 — No Live ΔΓ / ΛC / η_slip Flags in Evaluation Output ◌
Status: Gapped invariants are silently absent from evaluation output — no ◌ signals emitted.
What's missing: Every evaluation output MUST include flags for checks that were not performed.
Risk: Silent partial evaluation (FM-5) — callers cannot distinguish full evaluation from partial.
Remediation path: Add a gaps_present: list[str] field to TMMRuntime output. Populate with ["ΔΓ_not_measured", "ΛC_not_measured", "η_slip_not_measured"] on every call until those checks are implemented.
Owner: κ — quick implementation, no physics needed. Priority: HIGH.
