- Replaced legacy `compaction.strategy` and `remoteEnabled` settings with `compaction.methodOrder` across session maintenance, schema, and tests.
- Added automatic fallback mechanism to try subsequent compaction methods upon failure or unsupported model capabilities.
- Added mouse drag-and-drop reordering support and click handlers to multi-select settings submenus.
- Updated documentation and test suites to reflect ordered compaction strategy preferences and fallback chains.
- Replaced time-based sleeps and polling loops with event-driven promise resolvers and fake timers across agent and tool tests.
- Migrated test suites to share in-memory auth storage and fixtures using lifecycle hooks.
- Updated catalog model definitions, metadata, and configurations.
- 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.
Move the dead-end rearm probe below the mid-run turn-persistence barrier so prepareCompaction sees the just-finished assistant and tool result.
Delay message-end persistence in the regression and require compaction at the second tool boundary, before another provider request can be sent.
Fixes#7151
The dead-end mark parked the live tool-loop context permanently, but the array keeps growing: a later smaller tool result can move the oversized turn to the summarizable side. Recheck prepareCompaction each boundary and re-attempt once a cut point appears, instead of suppressing until provider overflow.
Added a regression proving maintenance re-attempts once a cut point becomes available.
Fixes#7151
Remember no-progress mid-turn compaction results for the live agent-loop context so later tool boundaries skip identical rescue work. The weak context key naturally resets for the next user turn.
Added a scripted regression covering one warning and one attempt per oversized tool-loop turn.
Fixes#7151
