+# Native certifiable Voting program
+
+## Objective and non-claim
+
+GovOPlaN may develop a native end-to-end verifiable Voting provider, but the
+current platform and bundled `local_confidential` provider are not certified
+voting products. Certification cannot be obtained by adding a label, tests, or
+general platform security controls. It applies to a precisely bounded Target
+of Evaluation (TOE), version, evaluated configuration, lifecycle, and evidence
+set assessed by an independent laboratory and certification authority.
+
+The native provider must therefore be an isolated assurance component behind
+`voting.provider.<id>`, not an implicit claim over all of GovOPlaN. Voting owns
+the governed ballot lifecycle and evidence projection; the TOE owns ballot
+secrecy, cryptographic casting, verification, tallying, and the evaluated
+ceremony. Policy, Access, Identity Trust, Encryption, Forms Runtime, Workflow
+Engine, Committee, Decisions, Audit, Records, and Reporting may support the
+journey without being silently pulled into the TOE.
+
+## Program stages
+
+### 1. Protection profile and legal target
+
+- identify election classes, jurisdictions, attack potential, voting
+  principles, accessibility duties, and retention obligations;
+- select the applicable BSI Protection Profile/TR and Common Criteria target;
+- engage a recognized evaluation facility before fixing the architecture;
+- write the Security Target, assumptions, threats, organizational policies,
+  security objectives, and evaluated configuration.
+
+### 2. TOE and trust boundaries
+
+- specify client, election server, bulletin board, verifier, tally component,
+  key ceremony, build/release chain, time source, and operator boundaries;
+- define electorate preparation and archival as explicit supporting processes
+  when they are outside the TOE;
+- prohibit node-local authoritative state and undeclared side channels;
+- define compromise, suspension, challenge, annulment, recovery, and evidence
+  export before implementation.
+
+### 3. Protocol and independent review
+
+- select a published, independently reviewed end-to-end verifiable protocol;
+- use reviewed cryptographic libraries and parameter suites rather than
+  designing new cryptography;
+- provide individual and universal verification without exposing vote choice;
+- define coercion-resistance claims truthfully, including what is not solved;
+- commission independent cryptographic and privacy review before production.
+
+### 4. Conformance implementation
+
+- implement canonical ballot/electorate/result/evidence encodings;
+- bind every cast and tally artifact to the frozen definition and electorate;
+- provide deterministic conformance fixtures, malformed-input suites,
+  property tests, fault injection, and cross-implementation verification;
+- preserve receipt privacy and prevent credentials, raw votes, or private keys
+  from entering GovOPlaN evidence projections;
+- expose certification state through `VotingProviderAssuranceDeclaration`.
+
+### 5. Controlled lifecycle
+
+- reproducible, signed builds and reviewed dependencies;
+- role-separated source, release, election, key-custody, and audit authority;
+- vulnerability handling, maintenance impact analysis, SBOM, provenance, and
+  controlled update path for in-progress elections;
+- production ceremonies, backup/restore, disaster recovery, secure deletion,
+  monitoring, incident response, and independently witnessed evidence.
+
+### 6. Evaluation and operation
+
+- laboratory pre-evaluation and gap remediation;
+- formal Common Criteria evaluation/certification of an exact TOE version;
+- target-specific deployment acceptance against the evaluated configuration;
+- certificate and maintenance-report monitoring;
+- fail-closed retirement or profile downgrade when validity expires or the
+  evaluated configuration changes.
+
+## Work-product gates
+
+Native implementation can proceed through fixtures and research profiles, but
+the `external_certified` runtime profile remains unavailable until all of these
+are independently evidenced:
+
+- approved Security Target and TOE boundary;
+- independent protocol/cryptographic review;
+- conformance and adverse-condition evidence;
+- controlled build and release provenance;
+- operational ceremony and recovery evidence;
+- valid product/version/configuration-specific certificate.
+
+Research, evaluation, and certified states are separate. A provider in
+evaluation may support a bounded test profile, but cannot become certified by
+configuration or administrator override.

+# POLYAS provider profile
+
+## Current integration position
+
+POLYAS is the first external provider selected for high-assurance GovOPlaN
+Voting. This is an integration decision, not a certification claim. Until a
+contracted machine interface, sandbox, exact product/version binding, and
+current certificate evidence are available, the integration remains
+operator-assisted and must not advertise the `external_certified` assurance
+profile.
+
+The public POLYAS material documents the Online Voting Manager, spreadsheet
+electoral-roll import, PDF/Excel result export, an election control portal,
+verification tools, SecureLink, and an electoral-board interface. It does not
+document a stable public API that is sufficient for an unattended GovOPlaN
+provider. The initial integration therefore uses the existing external
+provider contract as its target and keeps manual handoffs explicit:
+
+1. GovOPlaN freezes the ballot definition and electorate hashes.
+2. An authorized election officer creates and seals the corresponding POLYAS
+   election using a reviewed export.
+3. GovOPlaN records the POLYAS project reference, exact product/profile, and
+   handoff evidence without storing voter credentials.
+4. Voters enter the provider through its controlled launch or invitation path.
+5. An authorized officer imports signed result and protocol artifacts.
+6. GovOPlaN verifies the frozen binding, records aggregate results and evidence,
+   and retains certification, challenge, and annulment as separate actions.
+
+Operator-assisted imports must be labelled as such. Browser automation or
+screen scraping is not an acceptable production API.
+
+## Provider information required
+
+Before implementing unattended preparation, launch, status, or result
+acquisition, obtain from POLYAS:
+
+- the contracted API/protocol specification and versioning policy;
+- sandbox credentials and representative test-election fixtures;
+- supported ballot methods, weighting, voter groups, replacement, quorum, and
+  threshold semantics;
+- idempotency, revision, sealing, cancellation, outcome-unknown, and retry
+  behavior;
+- invitation and voter-authentication boundaries;
+- signed result, archive, audit, and verification artifact formats;
+- retention, deletion, subprocessor, location, incident, and DPA terms;
+- product/version-specific Security Target, certificate, maintenance reports,
+  validity period, and evaluated configuration;
+- recovery and continuity evidence for an election in progress.
+
+Credentials belong in governed credential envelopes. Raw selections, voter
+credentials, recovery codes, and private provider keys must never cross the
+Voting provider boundary.
+
+## Certification gate
+
+The BSI certificate `BSI-DSZ-CC-0862-V2-2021` for POLYAS CORE 2.5.0, including
+maintained versions described by its maintenance reports, was valid through
+2026-06-24. As of 2026-08-04, that validity date has passed. A new election must
+not be labelled `external_certified` from this historical certificate alone.
+
+The adapter must expose a `VotingProviderAssuranceDeclaration`. The runtime
+accepts `external_certified` only when the declaration pins:
+
+- the exact provider and implementation contract;
+- supported assurance profile and protocol version;
+- certification authority and reference;
+- an independently retrievable evidence reference;
+- a current validity window.
+
+The declaration is frozen with the ballot and revalidated before cast and
+finalization. Expiry, revocation, provider replacement, protocol change, or
+certificate substitution fails closed and requires explicit reconciliation.
