refresh or invalidate prompt_evidence, force_detect, and last_detect_generation
whenever the pane’s report state changes, before prompt admission runs. Ensure
agent_prompt_is_ready and agent.send use evidence consistent with the current
report state, including transitions to Blocked and back to idle.
- Around line 488-495: Update the readiness logic in the dispatch workflow to
use the resolved current agent consistently for both agent selection and
positive-evidence requirements; do not let a stale agent_session override
runtime detection when status.agent changes. Ensure a non-strict Gemini send
does not inherit Claude’s readiness requirement.

17268-17268: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winAdd app-level coverage for divider-adjacent cursor positions.
A typed divider inside the live composer is valid when the cursor remains on the divider with a blank row after it, and when the cursor moves directly to the next row. Add both geometries to this test, keep the closing rail below the cursor, and assert readiness in strict and non-strict modes through both prompt APIs.
The lower-level detector test already covers the direct-after-divider case. It does not cover the cursor-on-divider case or the app-level admission path.

- Line 598: Update the stale-composer check around `row_is_rail` so an adjacent
rail-shaped row alone does not classify the composer as stale; use a
Claude-specific completion signal or other semantic state instead of
visible-text heuristics. Preserve the stale-composer regression and cover live
input with a full-width divider immediately after the prompt and later input
before the lower rail.

Claude startup screens could receive prompt text before a live input composer existed. Prompt admission now requires live composer evidence for Claude and Codex, with optional
strict:true/--strictfor other agents. The default fallback for other agents is preserved.Readiness follows the current agent and integration reports. Visible multiline Claude composers, including typed divider lines, are supported without a 16-row limit. CLI, UHP fixtures, documentation, and regression tests are updated.
Addresses the prompt-admission proposal in #425.
Validation: the full locked suite passed 2,098 unit tests and 16 integration tests (5 existing tests ignored) before the divider follow-up. That follow-up passed all 14 Claude-related tests, formatting, and strict Clippy. Claude theme-picker rejection is covered by a fixture; the earlier isolated live launch verified normal composer detection.
No outstanding findings block merging.
Summary
This PR requires live composer evidence before submitting prompts to Claude and Codex, adds optional strict admission for other agents, and updates the CLI, UHP fixtures, documentation, and regression tests. The latest change clears Claude readiness for URL elicitation dialogs.
