Carbon claims.
Proved, not presumed.
LamSteward CarbonEvidence turns offset records, capture and removal evidence, activity data and reporting facts into one reproducible AirTight record. AI helps find, extract and explain; deterministic tools calculate; people approve.

RAG: CarbonEvidence Pack v1.0 + Northstar evidence◆ LOCAL
Can retirement R-24018 support the FY2026 market-instrument statement?
✦
Grounded answer
The record has project, vintage, serial range and retirement evidence. Ownership transfer is unresolved, so it should remain pending and must not be netted against the physical inventory.

The LamSteward product suite
Eight tools. One governed carbon record.
The CarbonEvidence Content Pack grounds retrieval, extraction, drafting, drawing, reporting, specialist behaviour and review. Users move between tools without losing source, method, statement or approval context.
The focused product wedge
Offset, capture and reporting—without collapsing the claims.
LamSteward connects evidence across the carbon lifecycle while preserving what each record can and cannot prove. It is an evidence and reporting control system, not a marketplace, verifier or capture controller.
Trace measured carbon flows.
Keep source, capture process, transport, storage or utilization, monitoring, mass balance and method versions in one reviewable chain.
Does not control equipment or assert engineering fitness.Reproduce every material number.
Link activity data to evidence, factor, formula, estimate, reviewer, approval and frozen software/content versions.
Does not provide an assurance opinion or legal determination.THE THREE-STATEMENT RULEPhysical inventory≠Contractual / market instruments≠Action impactNo silent netting
◆The first promise · AirTight
Sensitive evidence stays
inside your boundary.
AirTight blocks every outbound call and refuses to start if the boundary is not working. Activity data, commercial terms, supplier evidence, capture records, retirement documents and assurance work remain on hardware you control.

CarbonEvidence in action
The report is the output. The control system is the product.
A governed workflow connects evidence, deterministic calculation, separate statements, review and export. Approved results remain reproducible from frozen factor, method, pack and software versions.

The primary value layer
The CarbonEvidence Pack turns tools into
a reporting control system.
LamFia contributes less than half of the product value as the enabling application foundation. Most differentiated value comes from LamSteward’s evidence model, deterministic carbon workflows, governed templates, source/rights controls and specialist review rules.

The second promise · Markdown-first
The format you keep.
The language AI speaks.
Your work never disappears into a vendor database. Documents, prompts, agent definitions and text-defined diagrams remain readable files on your disk, with LGMD adding typed diagrams, assets and provenance without breaking the plain-text fallback.
- Author once. Export PDF, Word, slides or sheets.
- Diff every change. Use ordinary version control.
- Leave without extraction. Your content was always yours.
Desktop is the product
Install it. Open your workspace.
Start on your own hardware.
The signed desktop application is the default experience. A connected service inside your own cluster is available for enterprises with a platform team; cloud engines are optional and only used through policy-controlled hybrid routing.
Questions, answered plainly
What a climate team asks first.
The product claim should be testable on your own data and your own hardware.
Run one assurance-ready carbon cycle.
Use your own offset, capture, activity and reporting evidence. Measure time-to-answer, evidence coverage, reproducibility and review effort in a 4–6 week Carbon Evidence Readiness Sprint.
