Common is our abstract core library - the Rust crate that holds the trait definitions, the ActionEffect system, and the DTOs every other element in the fleet shares. If a shape is spoken across the IPC boundary, it lives here. This file records what we built in our voice, version by version. Format adapted from Keep a Changelog.

We turned Common into the single source of truth for the language-feature provider surface and the transport vocabulary the rest of the fleet consumes.

• PascalCase enforcement across 34 Rust files in Source/LanguageFeature/, Source/Transport/, and Source/TreeView/ (514 insertions, 705 deletions). Brought Common in line with the project-wide naming rule end-to-end.
• EvaluatableExpression + InlineValues provider types in ProviderType.rs so the workbench's debug surface has the shapes it reaches for at evaluation time.
• 19 LanguageFeature provider methods standardised: ProvideCallHierarchy, ProvideCodeActions, ProvideCodeLenses, ProvideCompletions, ProvideDefinition, ProvideDocumentFormatting, ProvideDocumentHighlights, ProvideDocumentLinks, ProvideDocumentRangeFormatting, ProvideDocumentSymbols, ProvideFoldingRanges, ProvideHover, ProvideInlayHints, ProvideLinkedEditingRanges, ProvideOnTypeFormatting, ProvideReferences, ProvideRenameEdits, ProvideSelectionRanges, ProvideSemanticTokensFull.
• Transport-layer refactor giving us CircuitBreaker.rs, IPC.rs, and gRPC.rs as the named primitives every other element consumes.
• 36 new TypeScript declaration files (.d.ts + .d.ts.map) for the Workers API surface so the renderer side gets accurate types.

• README expansion: +243 lines of comprehensive documentation covering the trait surface, the DTO conventions, and the transport vocabulary.

@cloudflare/workers-types rolled forward through the cycle. No source changes; pure dependency stabilisation.

@cloudflare/workers-types 4.20240721 → 4.20240925 series. Documentation styling refreshed (98 CSS lines in TypeDoc assets). Minor updates in Source/Function/Access.ts and Source/Function/Encrypt.ts.

We stood up Common's Cloudflare Workers library with a crypto-operations focus, plus the first 8 generated TypeScript declaration files (Function/*.d.ts, Interface/*.d.ts). Source/Function/Access.ts moved to PascalCase in the same window.

CODE_OF_CONDUCT.md refresh, README expanded by 12 lines, continuous @cloudflare/workers-types rolls. Maintenance-heavy cycle - no major new features.

• License expansion from 42 to 131 lines (AGPL-3.0 addition, October 4).
• TypeScript declarations restructured: 172 insertions across 18 Target/*.d.ts files in the new format.

• PascalCase conversions across Source/Interface/*.ts.
• 146 deletions of old-format declarations, 172 insertions of new format - the cutover was atomic.

We refreshed the documentation UI assets (icons.js, main.js, style.css) and rolled @cloudflare/workers-types continuously. Stable cycle, mostly dependency maintenance.

Full TypeDoc rebuild: 1,802 insertions in style.css and asset bundle.

69 files changed, 1,802 insertions - the first full documentation generation pass.

The first scaffold:

• Source/Function/Access.ts and Source/Function/Encrypt.ts - the initial crypto-operation surface.
• Cloudflare Workers API type definitions.
• TypeDoc documentation pipeline.
• GitHub Actions workflows + Dependabot configuration.
