- Implemented in-house, zero-dependency utility modules in `pi-utils` covering DOM manipulation, markdown parsing, templating, browser automation helpers, and terminal buffers.
- Migrated packages across the repository to consume the new internal utilities and `omptype` schema validators instead of external dependencies.
- Removed multiple external runtime and development dependencies including Zod, Marked, LRU cache, Turndown, and Puppeteer browser packages.
isUnexpectedStopCandidate only counted non-whitespace text blocks, so a stopReason:"stop" turn whose sole content was a signed thinking block bypassed the unexpected-stop guard entirely. #isEmptyAssistantStop treats signed thinking as terminal (not empty), so such stops fell through both recovery handlers and the agent silently stopped mid-task.
Count non-whitespace thinking blocks as candidates and feed the thinking text to the classifier when no text block is present.
Fixes#7499
- Added `features.unexpectedStopDetection` and `unexpectedStopModel` settings for opt-in behavior.
- Added assistant-stop handling to classify stop reasons and resume generation with retry prompts.
- Added unexpected-stop classifier logic with candidate checks, model fallback, and YES/NO parsing.
- Added retry tracking that caps auto-continues at three attempts and logs a warning when exceeded.
