Briefing

DEC-0042 requires hover and documentation Markdown to be represented through generic frontend models so LSP does not know PBS semantic or documentation internals.

Objective

Migrate LSP hover handling to generic frontend hover models while preserving PBS signature, kind, origin, detail, and Markdown documentation behavior.

Dependencies

• Depends on PLN-0111.
• Should run after PLN-0113 so generic symbol kinds and documentation fields are established.

Scope

• Define or finalize generic hover/documentation DTOs.
• Map PbsEditorialResolvedSymbol to generic hover output inside the PBS boundary.
• Update LSP hover composition to consume generic values.
• Preserve Markdown output and existing no-symbol fallback.

Non-Goals

• Changing the PBS [Doc] language feature.
• Reformatting authored Markdown.
• Implementing go-to-definition or references.
• Migrating signature help request handling, except for shared signature DTOs used in hover.

Execution Method

1. Inspect PbsEditorialResolvedSymbol, PbsEditorialSignature, and formatHoverMarkdown(...).
2. Ensure generic FrontendHover can represent:
   • display name;
   • symbol kind;
   • detail;
   • origin;
   • signatures;
   • documentation Markdown.
3. Add PBS mapping from PbsEditorialResolvedSymbol to FrontendHover inside the frontend language service.
4. Update CompilerLanguageServiceBridge.hover(...) to call generic hover capability and format generic hover values.
5. Keep Markdown composition deterministic: signature block, kind/origin metadata, then documentation.
6. Preserve empty/no-symbol fallback when hover capability is absent.

Acceptance Criteria

• LSP hover no longer consumes PbsEditorialResolvedSymbol.
• PBS documentation Markdown appears unchanged in hover.
• Authored Markdown is not reflowed or reparsed by LSP.
• Missing capability returns deterministic no-symbol hover behavior.

Tests

• PBS hover/editorial tests.
• LSP hover mapping tests asserting Markdown payloads.
• Documentation Markdown regression tests from DEC-0039 coverage.
• Missing hover capability fallback test.
