- Updated the `ai` package E2E tests to retrieve environment variables via `e2eApiKey` to ensure they only execute when E2E testing is enabled.
- Refactored the `scripts/ci-test-ts` runner to conditionally apply the `--only-failures` flag based on provided arguments.
- Removed configurable tab width support and the `display.tabWidth` setting across all packages.
- Deleted obsolete utility functions `getIndentation`, `getIndentationNoescape`, and `setDefaultTabWidth`.
- Standardized tab expansion logic to use a fixed `DEFAULT_TAB_WIDTH` globally.
- Cleaned up related configuration schemas, test suites, and internal API signatures to remove path-dependency.
- Added `chunkSize` configuration to coding-agent test buckets to prevent OOM errors in CI.
- Updated `codingAgentTestCommands` to generate multiple test processes when a bucket exceeds its chunk limit.
- Refactored `commandsForMode` to support flattened arrays of chunked test commands.
- Removed the `--only-failures` flag from workspace test commands so CI runs complete test passes.
- Raised native test mode parallelism from 1 to 4 for native and integration package execution.
- Removed the mnemopi Bun preload file and added explicit `./setup` imports in the changed test suites.
- Deleted the `RUN_EMBEDDINGS` flag path and shifted `MNEMOPI_NO_EMBEDDINGS` handling into per-suite before/after hooks.
- Excluded `packages/mnemopi` from the fast parallel CI test bucket with a note about missing fastembed models.
- Updated workspace-mode CI to run `workspaceTestCommand` with 8 workers instead of 4.
- Raised the documented ARC runner CPU limit from 8 to 16 in caching docs.
- Added explicit environment variable blacklists for credential and cache-related prefixes and names used by CI test runs.
- Added a helper that also strips provider API, OAuth, and bearer token variables by pattern.
- Updated test command spawning to pass a filtered environment, making suites run without inherited secret credentials.
- Added a setup-system-deps action with preloaded-runner guards and apt fallbacks.
- Updated CI workflows to download Linux x64 native artifacts and gate on native job success.
- Renamed coding-agent fast mode to singleton in scripts and test partitioning logic.
- Added settings test-state begin/restore helpers with recursive cleanup in affected tests.
- Added a mode-based `ci-test-ts.ts` runner with `--dry-run` support.
- Partitioned coding-agent tests into fast/ui/runtime/native/heavy buckets and separated workspace/native runs.
- Added coding-agent bucket modes that fail CI when a target bucket has no matching tests.
- Updated CI scripts/workflow to run the new TS buckets, use `omp-kata`, and gate releases on them.
