gateGHG is the production Green Governance control surface of the immo.quick Serverless Edition. Canonical emissions, supply-chain and evidence data are evaluated against fixed boolean conditions. The result is an explicit gate state rather than a probabilistic score.
gateGHG runs as a stateless Deno.serve sidecar inside compliancePipeline. It evaluates canonical ESG/GHG payloads against fixed invariants, produces a gate state and binds the concrete execution into a GateLog record. The specialised ESG cluster beneath it provides domain logic for GHG Protocol, ISO 14064, EU Taxonomy, CSRD/ESRS, CSDDD, EU ETS and additional governance rules.
Canonical payloads are checked for required fields and deterministic input conditions. Missing mandatory data can produce BLOCK or a contract-defined ABSENT state.
scope1_co2e · reporting_period · supplier_leiScope 3 and supplier data can be linked to existing LEI/entity resolution and provenance evidence. Missing provenance prevents positive closure without inventing an external blacklist.
supplier_identity_resolved · provenance_boundEncoded rules execute as referenceable boolean determinations. Successful states can use existing certificate/warranty-token paths; missing or conflicting conditions remain visible.
rule_id → true | falseA human override does not overwrite the original BLOCK/ABSENT state. It creates a new bound evidence record with caller_did, caller_role, executed_at and a relationship to the origin artifact.
retention_years = 10The concrete GateLog execution is bound with HMAC-SHA256 to gate name, input hash, details hash and executed_at. Processing-time measurements remain outside the signing path.
HMAC(key, gate:input:details:executed_at)The website makes no HSM anchoring claim. Current GateLog key material is described as an isolated environment secret; automated rotation is part of the declared operating model.
Deterministic computation cannot turn poor or incomplete input data into truth. External entity/UBO/Scope 3 sources therefore remain an explicit input boundary.
ANCHOR_PLACEHOLDER_MODE
No production witness or multi-jurisdiction finality is claimed while the required witness contracts are not active.
The gate pattern is designed as a Deno.serve function. It receives a canonicalized payload containing transaction metadata, energy labels, supply-chain attributes and certificate data, and evaluates only defined boolean conditions.
Transaction metadata · energy labels · supply-chain attributes · certificates.
No scores. No free-form weighting. Only defined true/false evaluations.
Exactly one deterministic gate verdict for the defined input state.
Input hash, output hash, HMAC, formula version, caller binding, execution time and retention.
Optional Merkle/anchor path where additional proof sealing is required.
PASSThe defined conditions of the gate pattern are satisfied.
WARNThe state is not necessarily blocking, but requires defined attention or follow-up review.
BLOCKAt least one defined blocking condition is not satisfied.
Processing-time measurements are excluded from the signing path. The same canonical payload under the same deterministic rules produces the same gate decision; identical input/output content produces identical hashes. The HMAC additionally binds the concrete execution through executed_at. It therefore should not be described as a time-independent identical value across separate executions.
The existing orchestration remains the primary structure. Green Governance is not inserted as an artificial additional stage in a sequential 0–7 chain.
Production Green Governance control surface: a deterministic, state-bound sidecar gate type within the existing Serverless orchestration.
gateLegalConflictWhere a trade-off between environmental/policy duties and other legal duties is detected, the conflict can be handed to the existing legal-conflict logic.
CommitmentAttestationCan be used where resulting proofs should additionally be bound as a commitment or included in a Merkle structure.
SovereignAnchor · ANCHOR_PLACEHOLDER_MODECurrent architecture status: placeholder mode. Witness contracts are absent. This page therefore makes no claim of production witness/anchor finality.
The current ESG/Green Governance cluster of the Serverless Edition consists of specialised sidecar gates. They process canonical inputs against fixed boolean conditions and return PASS, WARN, BLOCK or, where the relevant gate contract provides for it, ABSENT. The sidecars are orchestrated within compliancePipeline rather than represented as an artificial sequential Gate 0–7 chain.
gateGHGPROD · ACTIVEProduction umbrella ESG/GHG sidecar for canonical emissions, provenance and evidence data. It orchestrates the relevant specialised determination logic and binds the outcome into the existing GateLog and Execution Rights architecture.
gateGHGProtocolACTIVEValidates completeness, source attribution and the documented mathematical calculation path of greenhouse-gas raw data.
gateISO14064ACTIVEEvaluates documented GHG measurement methodology and formal evidence, including available auditor signatures. The gate contract can return ABSENT where required formal evidence is missing.
gateEUTaxonomyACTIVEEvaluates activity, NACE and investment data against encoded technical screening criteria and DNSH conditions and can use GHG data from the sidecar cluster as a dependency.
Open existing gate →gateCSRDACTIVEEvaluates structural integrity of sustainability reporting and routes climate-related data to the relevant ESG sidecars for specialised deeper checks.
Open existing gate →gateCSDDD_SUPPLY_CHAINACTIVELinks supplier identity and provenance with human-rights and environmental due-diligence conditions; LEI/entity states can be incorporated through the existing identity/register logic.
gateEUETSACTIVEEvaluates encoded reporting, allocation and allowance conditions for installations subject to emissions trading. Uncovered emissions states can produce HARD_BLOCK under the gate contract.
gateGovernanceRulesACTIVECompiled ruleset for declared climate targets, climate-risk disclosure and financial-product classification. Checks run as efficient sub-functions inside the existing ESG gates.
The following labels are system-internal names for encoded governance rules. They do not claim that German or European statutes or regulations exist under these names. External legal and standards sources remain referenced separately.
Internal invariant for provenance-bound sustainability data. Subsequent changes remain visible only as a new attributable state; the original evidence state is not overwritten.
ORIGINAL_STATE != OVERRIDDEN_STATEInternal provenance invariant for Scope 3 and supplier data. Incoming data is treated as supportable within the defined chain only where identity, provenance and required evidence bindings resolve.
PROVENANCE_CLOSURE = REQUIREDInternal environmental invariant linking encoded climate/environmental conditions to available measurement and legal states. Article 20a GG can be referenced as an external constitutional source at the Gate 0 layer; the internal rule does not replace constitutional assessment.
ENVIRONMENTAL_INVARIANT → GATE 0 REVIEWCompare an explicit LLM inference scenario with a deterministic immo.quick gate path. Every assumption remains visible, every formula reproducible, and every result is labelled as derived. Change the parameters and test the scenario yourself.
Under the stated parameters, the modelled energy demand of the deterministic path is lower than the selected LLM comparison scenario.
Reserved for values actually measured against a documented system boundary.
External scientific or official reference values with disclosed provenance.
User-set scenario assumptions. Editable, but never presented as measured truth.
Results calculated arithmetically from the visible inputs.
Reference note: Standard/reasoning LLM values are published scenario references, not universal model constants. Germany 2024: 363 g CO₂/kWh according to the German Environment Agency (Umweltbundesamt). The immo.quick energy value remains explicitly labelled as a technical estimate until backed by a documented measurement series. Cost values remain configurable scenario assumptions. Household and tree equivalents are illustrative only and are not core ESG metrics.
