Stage writable event-field overrides by tool call id so they can be applied at the correct point in the turn lifecycle. Capture input overrides from tool_call_complete, capture output overrides from tool_result, and clear staged overrides defensively at turn start and shutdown.
Also honor user_message text overrides when starting a turn, add the helper that applies staged overrides to the agent at dispatch boundaries, and cover the behavior with tests for staged input/output overrides.

The root cause was a two-part bug:
1. Engine slot management (tui_engine.zig): The app rebuilds its full
component list on every new transcript entry. The old approach drained
every slot then re-added them all, resetting every component's render
baseline. When earlier content had scrolled into native scrollback
(viewport_top > 0), the engine's viewport-escape rule escalated any
cut above the viewport top to a scrollback-clearing full redraw — the
visible flash on every streamed block while a tool call was expanded.
Fix: replace drain+rebuild with syncComponents(), which reconciles the
live slot list in place by finding the longest common prefix and suffix
(matched by component pointer). Prefix and suffix slots keep their
baselines verbatim; only the changed region in the middle gets new
empty slots. A pure insertion (the dominant case: a new transcript
entry appended just before the pinned input+footer suffix) stays on
the differential path with no clear. A structural change (slot
replaced or removed) sets force_full for correctness.
2. RenderCache dirty signal (tui_component.zig): firstLineChanged()
was returning the retained changed_from diff index even when the cache
was clean. A first-paint store records changed_from == 0, so a clean
but previously-rendered component was pegging the differential cut to
line 0 on every subsequent frame, making unchanged slots above the
insertion point drag the cut all the way up. Fix: when the cache is
clean, firstLineChanged() returns null unconditionally. The recorded
changed_from is now internal render bookkeeping only, not a live
signal.
Additional changes:
- ToolUse.collapsed_tail_lines raised from 5 to 8 lines.
- ToolUse collapsed-view test updated to use 12 output lines and
collapsed_tail_lines symbolically so the numbers self-document.
- tui_app.zig: override-slot test comment and assertion clarified to
reflect that the override owns the slot pointer (not just renders it),
and the SWAPPED-AT-DETAILS render check replaced with a pointer-equality
check.
- lua_event_bridge.zig: minor related fixes.
- New tests: syncComponents middle-insertion no-clear, syncComponents
structural removal forces full, syncComponents override swap; streaming
expanded-tools no-clear regression test in tui_app.
Add addUserText helper; update all call sites2026-06-10T18:17:27Ztt@tjp.lol2026-06-10T16:06:07Zurn:sha1:bb85e867bc938138f29fb45230169af1ba60761c
Conversation.addUserMessage now takes a []ContentBlock (symmetric with
addAssistantMessage). Introduce a thin addUserText wrapper in agent.zig
for the plain-text case and update every call site in agent.zig and
anthropic_messages_json.zig accordingly.
