# Java Analyzer Prep — SCANNER-ANALYZERS-JAVA-21-008

Status: Draft (2025-11-20)
Owners: Java Analyzer Guild
Scope: Resolver + AOC writer emitting entrypoints/components/edges with reason codes/confidence; depends on 21-007 outputs.

## Dependencies
- 21-007 manifest metadata collector outputs (signers, manifest attributes) required to seed resolver inputs.
- CoreLinksets/Concelier build health to allow Java analyzer test runs.

## Proposed resolver outputs
- `entrypoints[]`: `{id, path, manifest_main_class?, agent_class?, start_class?, module}`.
- `components[]`: modules/JARs with `{purl?, sha256, module_name?, signed?, signer_ids[]}`.
- `edges[]`: `{from_entrypoint, to_component, reason_code (jpms|cp|spi|reflect|jni|runtime), confidence, evidence}`.
- Deterministic ordering: sort edges by (from_entrypoint, to_component, reason_code).

## Tests/fixtures
- Place fixtures under `src/Scanner/__Tests/Fixtures/java/21-008/*` covering jpms, classpath, SPI, reflection, JNI cases.
- Regression tests: `ResolverOutputs_AreDeterministic` and `EdgesIncludeReasonAndConfidence`.

## Open decisions
- Exact confidence scale (0–1 vs categorical) to align with downstream Surface.
- Whether to emit runtime edges in this task vs deferring to 21-010.

## Handoff
Use this doc as the PREP artefact for 21-008; update once 21-007 outputs and confidence scale are finalized.
