- Added `tui.scrollbackRebuild` configuration with interactive startup/controller wiring to apply `setScrollbackRebuild`.
- Exposed prewalk session state in `SegmentContext` and rendered a dedicated prewalk segment/icon in the status line.
- Added divergence-aware TUI full-paint logic that enables scrollback erase-and-replay rebuilds for non-multiplexer divergence cases.
- Updated rendering and streaming tests to verify rebuild behavior (`3J`) and eliminate stale marker expectations under drift scenarios.
- Implemented a unified benchmark normalization layer to handle metrics and artifacts across harbor, edit, and snapcompact benchmarks.
- Integrated the TypeScript edit benchmark directly into the manager, migrating logic and deprecating the standalone package.
- Updated the API and database schema to support standardized benchmark configurations, metrics, and trace-based reporting.
- Enhanced the UI to visualize comparative performance metrics, including pass rate, cost, and latency deltas for benchmark runs.
- Replaced markdown-style headings with concise `¶user:`, `¶think:`, `¶ai:`, and `¶call:` scope markers.
- Updated the serializer to merge consecutive messages or blocks of the same type under a shared prefix.
- Updated the documentation prompt to reflect the new compact formatting and scope rules.
- Added regression tests verifying scope merging and correct formatting of tool calls and intents.
- Made resolveShapeForText choose silver16-bw for CJK-heavy auto transcripts while preserving explicit variants and unsafe glyph protection.
- Added silver16-bw to the snapcompact shape settings submenu and renamed unsupported-glyph warnings.
- Covered auto shape selection, explicit variant precedence, unsafe glyph scans, and settings option parity.
Fixes#4486
fix(compaction): cap snapcompact frame payloads (#3866)
Bound rebuilt snapcompact image payloads by a per-request base64 byte
budget so long sessions stop re-sending multi-megabyte standing image
archives on every provider request; auto-compaction falls back to
context-full summaries when snapcompact output is too large.
Resolved snapcompact.ts conflict against the main font-rendering refactor
by keeping both renderabilityProbeText and the frame-budget helpers.
Fixed historyBlocks to emit the omitted-frame notice before the kept
(newer) images, since the byte budget drops the oldest frames — keeping
reconstructed blocks oldest-to-newest (addresses Codex P2 review).
Fixes#3792
When legacy snapcompact archives exceed the per-request byte budget, retain frames from the newest end of the archived middle and restore oldest-to-newest order for the kept subset.
Bounded persisted snapcompact image archives by base64 byte size so large sessions stop re-sending multi-megabyte frame walls on every provider request.
Auto snapcompact now falls back to context-full summaries when rendered frame payloads exceed the byte budget, and legacy oversized archives omit over-budget frames during LLM context rebuilds.
Fixes#3792
- Added Silver.ttf TrueType font support to `pi-natives` with automated fallback logic for bitmap font rendering.
- Implemented wide code point detection and cell-width calculation to improve CJK character handling and layout.
- Introduced dynamic font-aware preflight probing via `resolveShapeForText` and `renderabilityProbeText` for better font selection.
- Enabled semantic emoji folding and improved text normalization to handle non-Latin characters and emoji filtering.
