Independent post-build review found three gaps, all one family: input that
changes the composer without a prediction leaves the DISPLAYED cursor stale
for one RTT, and anchoring a new run on it painted ghosts one cell off
(blank-neutral, so they lived out the full TTL: "tehh" on
backspace-then-retype, exactly on the links the feature targets).
Fix: the addon now HOLDS new predictions after any such edit (backspace with
nothing outstanding = deleting echoed text, clearPredictions, and now also
IME/plain-paste 'text' commits, which the hook clears like 'clear') until
the next PARSED write releases the hold. The inline predictChar reconcile
deliberately does not count: only the emitter pass or the public
reconcile() is the display-caught-up contract. Worst case is exactly one
unpredicted keystroke, whose own echo releases the hold. Also patched the
one bypass path the PR had missed: _handleCjkInput now clears predictions
like insertTerminalText and the other bypass sends.
Package suite 230, vm gating 85, E2E 10/10 all green after the change.

terminal-ui.js: _localEchoPolicy ('buffer'|'predict'|'off') computed at the
end of _updateLocalEchoState with _localEchoEnabled keeping its exact 1.12.2
values; _predictHookOnData called as a plain statement between the buffer
block and Normal Mode (visual-only, try/catch, never returns, never touches
_pendingInput); classifyPredictInput + isCodexComposerRow (baseY-based,
measured /^> /-signature gate) on CodemanTerminalInput; construction beside
the LocalEchoOverlay from the separate bundle with graceful absence;
insertTerminalText/clearTerminalInput/setFontSize/applyTerminalSkin clear or
refresh predictions. app.js: fields + tab-switch and SSE-reconnect clears.
voice-input '\r' branch and keyboard-accessory sendKey clear predictions
(both bypass onData). sendEnterKey needs no change: codex falls through to
the immediate-flush branch.
Layer 4 vm tests: classify truth table (20 cases), composer-row gate incl.
the baseY pin, policy matrix with the 1.12.2 invariants untouched, wire
neutrality + throwing-predictor pins. Stale mobile keyboard codex-buffering
tests repointed at claude; new codex twin asserts write-through streaming,
prediction spans and TTL self-heal.
