Codeman maintainer a30524060a feat(predictive-echo): PredictiveEchoAddon + Layers 1-3 test suites (0.2.0)
Mosh-style write-through prediction: the consumer sends every keystroke
unchanged; the addon paints predicted glyphs and reconciles against the
parsed buffer. Confirm = cell match + cursor advance (placeholder-safe,
repaint-safe); two-pass mismatch cascade with neutral blanks (measured:
codex clears its placeholder on first echo); TTL bound; baseY-based line
reads; scroll/resize/off-row clears. Zero edits to zerolag-input-addon.ts.

Tests: 30 addon-law specs + renderer geometry (fake performance clock for
TTL/grace), 6 replay suites running the real algorithm through a real
@xterm/headless parser fed by the recorded codex fixtures, and a
500-iteration seeded fuzz with per-op span/record + grid invariants.
227 total, the pre-existing 175 untouched.

arkonandClaude Opus 4.6 a8a6c1a648 test: add comprehensive overlay tests for visual fixes and setPrompt
New cell-dimensions.test.ts (8 tests): DPR conversion, charTop/charHeight,
null cases. Overlay renderer tests (+12): cellH+1 seam fix, span centering,
no-transform, ligature disabling, multi-line cursor. Addon tests (+9):
setPrompt() strategy switching, tab-switch cycle, ghost artifact prevention.

arkonandClaude Opus 4.6 d14ac9de65 feat: add xterm-zerolag-input standalone library
Extract Claudeman's local echo overlay into a reusable xterm.js addon
at packages/xterm-zerolag-input/. Provides instant keystroke feedback
via a DOM overlay, eliminating perceived input latency over high-RTT
connections (SSH, mobile, cloud IDEs).

- Zero dependencies, compatible with xterm v5.x and @xterm/xterm v5.4+
- Configurable prompt detection (character, regex, or custom function)
- Flushed text tracking for tab-switch / deferred echo scenarios
- Per-character grid-aligned rendering matching xterm's canvas output
- 56 tests passing (prompt finder, overlay renderer, full addon lifecycle)
- Dual CJS/ESM build with full TypeScript declarations

Claudeman source is unchanged — migration to consume this lib is a
separate follow-up.
