2026-08-27 Infrastructure TypeScript lint consistency audit

Work Done

• Audited all seven TypeScript projects in the mono chore/linters worktree.
• Confirmed that current Nx lint runs Biome and Oxlint complexity for six projects, with the intentional Oxlint-only apps/docs exception for external/generated Astro content.
• Ran all seven TypeScript Nx lint targets without cache; all passed.
• Identified incomplete Nx cache inputs, missing Biome pre-commit coverage, mixed Biome lint/check semantics, and parse-error skipping.
• Reported exact findings and recommended a shared typescriptLint named input.

Lessons Learned: Pitfalls

• A project being selected by nx affected does not prove its lint cache key includes every file that the lint command reads.
• Root linter configuration files must be explicit Nx inputs for nx affected and cache invalidation to work reliably.
• The branch’s committed dashboard lint script omitted Biome; the current worktree fixed it with an uncommitted edit.

Lessons Learned: Improvements

• Document the intended TypeScript lint contract: Biome plus Oxlint for normal projects, and Oxlint only for generated/external docs.
• Provide one shared Nx lint input that covers project lint files and both root linter configs.
• State whether Biome formatting and assist checks belong in the lint target or a separate CI format-check target.
