Mainline

Integrated frontends

These lanes are present in the integrated LawVM development line. “Integrated” describes repository presence; release stability, legal authority, and replay maturity each require separate evidence.

Finland

The reference replay lane for a declared Finnish corpus: source archives, Finnish amendment-language compilation, point-in-time state, provenance, and comparison-surface classification.

Authority / source: Enacted Statute Book material is the replay source; the Finlex updated/derived text is a fallible comparison surface. Source state: bounded source-complete subset.

Claim ceiling: Bounded replay construction evidence over a declared Finnish corpus, compared with a declared derived/updated surface.

Boundary: Official status remains with Finnish sources and institutions; source XML/HTML differences, corrigenda, manual frontiers, and unresolved deterministic or source/timeline checks remain explicit.

Pilot-ready use: Bounded consolidation QA and FI/SV expression-inventory work; recurring institutional operation is not yet proven.

Local need: Bilingual legal review, Finlex workflow knowledge, and an institutional pilot sponsor.

Next gate: Close current deterministic and source/timeline identity frontiers.

Estonia

An authoritative-consolidation consistency frontend over Riigi Teataja sources, with a reviewable comparison path and one externally confirmed correction.

Authority / source: Riigi Teataja operates an official consolidation regime; LawVM uses a bounded source-complete subset for consistency checking.

Claim ceiling: Replay can produce reviewable consolidation candidates; one reported omission was confirmed and corrected.

Boundary: The official consolidation remains a comparison surface, not an infallible reference or automatic replay authority.

Pilot-ready use: A bounded publisher-consistency audit with source-linked candidate review.

Local need: Riigi Teataja source and drafting expertise plus an agreed recurring-disposition workflow.

Next gate: Stabilize source and replay semantics for recurring evidence production.

United Kingdom

A legislation.gov.uk workbench for effects, versions, extent, commencement, source chains, replay diagnostics, and comparison-surface/pathology classification.

Authority / source: Official effects and version data are evidence inputs to a bounded source-complete subset, not silent replay authority.

Claim ceiling: Phase-owned effect/version and bounded replay evidence with explicit source and manual-compilation accounting.

Current maturity: Observe-only effects, version, source-chain, and commencement diagnostics for a bounded corpus; not an automatic consolidation service.

Boundary: No broad claim that every UK law has a complete source chain or fully replayed current text.

Pilot-ready use: Effects, version, source-chain, and outstanding-change diagnostics for a bounded corpus.

Local need: Publication-workflow expertise and a source-complete benchmark tranche.

Next gate: Close source-chain and manual-compilation frontiers without turning effect metadata into silent authority.

New Zealand

An API-backed source corpus with typed effects and five operation-family dry-run checks against before/after witnesses.

Authority / source: Official version data supplies before/after witnesses; source state remains acquisition-oriented rather than a complete replay universe.

Claim ceiling: Emitted dry-run candidates can be compared with before/after witnesses for selected operation families; no aggregate accuracy rate is claimed.

Boundary: End-to-end operation coverage remains limited and actual canonical replay is deliberately blocked.

Pilot-ready use: API/source conformance and witnessed dry-run expansion for selected operation families.

Local need: A pinned, denominator-complete transition corpus and local drafting review.

Next gate: Increase pinned witness-denominator coverage before promotion.

Norway

Structured amendment indexing, replay experiments, verification, commencement blockers, and source inspection over modern public-source chains.

Authority / source: Official amendment sources drive an acquisition-stage modern-source lane.

Claim ceiling: Structured-source and replay experiments over available modern public sources.

Boundary: Historical source access is weak before roughly 2001, and contingent commencement often blocks deterministic state.

Pilot-ready use: Modern-source and commencement-readiness assessment for a bounded domain.

Local need: Historical source access and authoritative interpretation of contingent commencement.

Next gate: Acquire historical sources and explicit commencement evidence.

Sweden

Official SFS artifact preservation, act parsing, current-text ingestion, and first-pass operation artifacts. It also exercises shared Swedish-language and parallel-expression infrastructure.

Authority / source: Official SFS amendment artifacts drive an acquisition-stage source lane.

Claim ceiling: Official-source preservation, parsing, and first-pass operation artifacts; broad replay fidelity is unmeasured.

Boundary: Broad current-law replay fidelity is not yet established; public historical sources are strongest from roughly 1999 onward.

Pilot-ready use: Official-artifact preservation, structure inventory, and transition-source feasibility.

Local need: A source-complete transition sample and Swedish drafting-language adjudication.

Next gate: Build source-complete transition subsets and dry-run witnesses.

Assess Sweden Discuss a pilot Contact

European Union

CELEX/ELI acquisition, consolidation, treaty, impact, and act-modeling experiments across a multilingual legal system.

Authority / source: CELEX/ELI sources support an acquisition-stage, source-only lane with authority declared per expression and artifact.

Claim ceiling: Exploratory CELEX/ELI acquisition and legal-resource modeling.

Boundary: Exploratory modeling and acquisition only; outside the Finland replay-construction claim.

Pilot-ready use: CELEX/ELI identity, manifestation, expression, and relationship conformance for a bounded corpus.

Local need: A scoped legal domain, authoritative expression rules, and effect-evidence review.

Next gate: Define bounded effect and expression evidence subsets.

United States federal

United States Code import, source bootstrap, amendment-source discovery, classification, and scale experiments over a fragmented publication regime.

Authority / source: Official source-law and codification artifacts support an acquisition-stage, source-only lane.

Claim ceiling: Source acquisition, bootstrap, import, and classification evidence for one bounded federal title or subject.

Boundary: Historical replay requires complete amendment-source and codification relationships for the selected scope.

Pilot-ready use: Source, codification, and classification readiness for one bounded title or subject.

Local need: Authoritative source-law/codification mapping and a deliberately narrow evaluation corpus.

Next gate: Resolve amendment-source and codification relationships for a bounded title.

Recently integrated

New source regimes in the shared line

These four frontends were integrated on 14 August 2026. Their source, parsing, replay, and local-review ceilings remain independent; the merge itself grants no legal or execution authority.

Japan

Archives e-Gov catalogs, revision histories and XML, bulk XML, attachments, and House enacted text. The lane carries loss-preserving source structure into typed amendment lowering, temporal selection, replay, and review dossiers for bounded families.

Authority / source: e-Gov and enacted-text sources support a source-owned history and transition lane.

Claim ceiling: Observed source histories, typed lowering, and bounded replay dossiers for supported families; broad corpus replay is not claimed.

Pilot-ready use: e-Gov source, version, XML-structure, attachment, temporal, and bounded-family replay assessment.

Local need: Japanese amendment-clause expertise and a larger set of independently witnessed transitions.

Next gate: Expand the witnessed corpus and promote only source-complete operation families.

Assess Japan Discuss a pilot Contact

South Korea

Combines typed, resumable official-source acquisition with observed-state histories and bounded Korean amendment parsing, lowering, and replay families. Configuration, transport, unsupported syntax, and comparison residuals stay explicit.

Authority / source: Declared official-source lanes and preserved observed snapshots remain distinct from comparison and replay claims.

Claim ceiling: Observed source histories and bounded typed amendment-replay families over witnessed snapshots; broad corpus completeness is not claimed.

Pilot-ready use: Credentialed acquisition, observed-state history, and bounded-family replay assessment for one declared lane.

Local need: Authorized API credentials, a measured source-complete corpus, and Korean legal-source expertise.

Next gate: Complete the official-source corpus and widen only independently witnessed families.

Assess South Korea Discuss a pilot Contact

Poland

Archives official ELI/Sejm identities and manifestations, lowers supported Polish amendment clauses to typed operations, drives the shared replay seam, and keeps commencement, correction, checkpoint, and comparison evidence separate.

Authority / source: Official ELI/Sejm sources own source identity and amendment evidence; checkpoint and comparison surfaces never repair replay.

Claim ceiling: Source-first Polish evidence with typed amendment lowering and conservative replay for supported, source-complete families.

Pilot-ready use: ELI identity, manifestation, clause-family, commencement, and bounded replay assessment.

Local need: Polish amendment-language review and independently pinned before/after witnesses.

Next gate: Expand corpus-wide family coverage while preserving every unsupported construction as a typed residual.

Assess Poland Discuss a pilot Contact

Switzerland

A bounded federal Fedlex frontend for post-30 May 2022 material: Work–Expression–Manifestation identity, impact inventory, applicability-dated transition bundles, German/French/Italian alignment, typed admission, and a read-only replay audit.

Authority / source: Fedlex sources support a bounded source-complete post-2022 subset; acquisition records and comparison expressions do not grant replay authority.

Claim ceiling: Swiss federal source, impact, cross-language admission, and exact read-only replay evidence for a bounded fixture cohort; no broad replay profile.

Pilot-ready use: Fedlex identity, impact, applicability date, expression completeness, structural alignment, and bounded transition assessment.

Local need: Swiss federal drafting expertise and German/French/Italian legal review for a bounded tranche.

Next gate: Expand source-complete transition cohorts without promoting comparison text or partial language groups.

Structured-operation regime

Open Law Library

This frontend tests LawVM against a cooperative XML source language whose publisher declares explicit codify:* operations. It is a frontend for a publication regime, not a claim about every jurisdiction using the platform.

Open Law Library

LawVM parses supported codification instructions, replays them against the prior XML tree, checks that writes stay inside declared targets, and compares the result with a publication snapshot. Unsupported lifecycle or action families remain owned findings.

Authority / source: For the public Maryland demo, local clones of law-xml provide the structured source and law-xml-codified provides a declared publication comparison surface.

Claim ceiling: Audit whether a supported declared codify:* operation produced the observed publication snapshot without unexplained mutation.

Boundary: The bounded claim covers structural conformance of declared operations. Maryland legal correctness, prose-derived Register amendments, and publisher authority require separate sources and competent review.

Pilot-ready use: Archive-free structural evidence pack and publication-operation conformance over a pinned repository snapshot.

Local need: Publisher documentation and jurisdiction-specific review for annotation, applicability, and lifecycle semantics.

Next gate: Freeze a reproducible public corpus snapshot and close the remaining structured-operation semantics.

How to compare frontends

The axes that matter

Source

Are official artifacts inventoried, archived reproducibly, and complete for a declared subset?

Structure and effects

Is source structure loss-preserving? Are amendment effects merely candidates, typed, dry-run checked, or promoted?

Replay and point-in-time state

Is mutation unauthorized, shadow-only, bounded and promoted, or broad? Can point-in-time state be materialized?

Verification

Are there contract tests, independent before/after witnesses, corpus accounting, or an externally confirmed disposition?
