3f75df0503cd36784600164b3594d3ebf9e63b19 Mon Sep 17 00:00:00 2001 From: "Michael J. Jabbour" Date: Wed, 15 Jul 2026 13:25:17 -0400 Subject: [PATCH 2/8] fix(tui): stop bottom status bar from echoing the turn title MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The bottom persistent status bar's stage text and the top per-turn transcript record (the committed Plan block) both derived from the same turn title, so when nothing more specific was happening the bar fell back to f"Working on {title}" -- a verbatim duplicate of the permanent record already written to scrollback. Introduce current_activity_label() in layered_repl_status.py as the single source of truth for what's happening right now in the bar. Precedence: active agent-lane delegation > an active plan/tool step > a streaming response > a distinct working idle indicator. The turn title is no longer part of this precedence at all -- it stays exclusively in the permanent per-turn record, so the two surfaces never collide. _working_stage() now delegates to the shared helper instead of building its own fallback chain (which included the removed title echo). Lane activity now also outranks a stale _task_tracker.active_step_text() and a lingering stream preview, since delegated work is the most specific signal available. The same layered_repl_status.py diff also carries footer colorization (_footer_fragments/_footer_part, applying class:mode.*/status.risk accents to the plain toolbar text), palette-visibility and queued-message-bar rendering (queued_bar_text, the palette_open/lane_focused hint precedence), and the capability_hint_overrides plumbing into the footer call -- none of which are mentioned by the summary above; they are included here because they already shipped as part of this same file in the original commit and are exercised by its own test coverage. Fix-back (this revision): a prior push of this commit did not build or test standalone -- confirmed by re-running `git worktree add` + a fresh `uv sync` against the commit in isolation, which reproduced: - ImportError: cannot import name 'TOKENS' from amplifier_app_cli.ui.layered_repl_style - pyright: no parameter named "hint_overrides"/"palette_open"/"lane_focused" on format_bottom_toolbar_text (layered_repl_status.py:82,110,111) - a latent AttributeError risk: lane.render_tree(...) has no implementation on AgentLaneSnapshot - (found during isolated re-verification, not in the original review) an additional ImportError in tests/test_layered_repl.py for amplifier_app_cli.ui.layered_repl_keys, and a runtime AttributeError from the still-unimplemented capability_hint_overrides() on LayeredReplApp Root cause: this file was authored and verified against a dirty working tree that already contained later, uncommitted work (a token-based theme system, a capability-hint-label catalog, and a keybinding-table refactor). The production diff for *this* commit only ever touched layered_repl_status.py, but its verification ("1946 passed", "pyright clean") was run against the dirty tree, not the isolated commit -- so the missing dependencies went unnoticed. Fix: add the minimum each existing reference in layered_repl_status.py needs to resolve, without pulling in the larger uncommitted refactor those dependencies eventually belong to: - amplifier_app_cli/ui/layered_repl_style.py: add a `TOKENS` dict with only the four keys layered_repl_status.py and its test coverage reference (dimmer, green, orange, bg_chrome), matching the hex values already used for the same roles in the existing LAYERED_REPL_STYLE. LAYERED_REPL_STYLE itself is untouched. - amplifier_app_cli/ui/footer.py: add `palette_open`, `lane_focused` (threaded into `_hint_levels()` with a literal-string hint tuple in the same style already used for `approval_pending`) and `hint_overrides` (accepted and intentionally unused -- no keybinding-label catalog exists at this revision, matching the existing `del image_paste_available` precedent in the same function). - amplifier_app_cli/ui/agent_lanes.py: add `render_tree()` to AgentLaneSnapshot, reusing the existing `_status_summary`/`_format_cost`/ `_truncate_cells` helpers already used by `render()`. - amplifier_app_cli/ui/layered_repl_terminal.py: add a minimal `capability_hint_overrides()` returning `None` on LayeredReplTerminalMixin -- layered_repl_status.py calls `self.capability_hint_overrides()` at runtime and no concrete implementation existed anywhere in this commit's tree, which crashed 51 tests with AttributeError. - tests/test_layered_repl.py, tests/test_layered_repl_visual_layout.py: revert the handful of assertions (and one net-new test) that had leaked in from the same dirty tree and exercised functionality this commit never implements: the layered_repl_keys/build_layered_key_bindings rename (the production code here still defines _build_key_bindings in layered_repl_layout.py), the composer edge-window/separator-row/queued- container layout, the "[mode] then prompt-marker" ordering swap, the "shift-tab"->"shift+tab" and "ctrl-o expand"->"click or ctrl-o expand" hint-text rewording, palette height/grouping changes, the "mode " footer prefix, the y-shortcut approval keybinding, and "Plan ·" prefix labeling in the committed plan record/plan pane. None of the production code for any of that exists in this commit; restoring the original assertions makes the test diff match what this commit actually ships. The assertions that do test this commit's real behavior change are kept: "Coordinating N agents" (not the echoed title) taking precedence in the working bar and live-agent-tree layout, and the working bar's distinct idle indicator. Verified in total isolation (git worktree add of this commit alone + a fresh uv sync, matching the reviewer's method): uv run pytest -q fully collects and passes, uv run pyright amplifier_app_cli/ui/layered_repl_status.py is clean, and ruff check/format are clean on every file this commit touches.

Jabbour" Date: Wed, 15 Jul 2026 13:50:02 -0400 Subject: [PATCH 3/8] fix(tui): narrow transcript reflow deferral to active streaming only MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit TranscriptReflowController deferred rewrapping already-printed transcript history for the entire duration of a running turn, not just while output was actively being appended. `_reflow_stream_active` gated on `execution_state["running"]`, which stays true for a whole turn -- including long stretches with nothing new printed yet (e.g. mid-tool-call waiting on a shell command). A resize during that idle window was silently held until the turn completed, creating a visible width seam between stale-wrapped history and the correctly-wrapped live preview. Narrow the gate to check only whether a stream preview is actively present (genuinely being painted), dropping the turn-wide running check. A running turn with no live append now reflows immediately on resize; a turn with an actively streaming preview still defers the rebuild, preserving the original guarantee of never repainting history under live output. Adds regression coverage in tests/test_resize_reflow.py: - reflow is not deferred when running but nothing is streaming (new) - reflow is still deferred while a stream preview is present (guard) Fixes: "resize doesn't work perfectly" mid-turn report. 🤖 Generated with [Amplifier](https://github.com/microsoft/amplifier) Co-Authored-By: Amplifier <240397093+microsoft-amplifier@users.noreply.github.com> --- amplifier_app_cli/ui/layered_repl.py | 189 ++++++++- tests/test_resize_reflow.py | 585 +++++++++++++++++++++++++++ 2 files changed, 773 insertions(+), 1 deletion(-) create mode 100644 tests/test_resize_reflow.py diff --git a/amplifier_app_cli/ui/layered_repl.py b/amplifier_app_cli/ui/layered_repl.py index 9fd2e49f..343482e2 100644 --- a/amplifier_app_cli/ui/layered_repl.py +++ b/amplifier_app_cli/ui/layered_repl.py @@ -5,6 +5,7 @@ import asyncio import sys from collections.abc import Callable +from dataclasses import replace from time import monotonic from typing import Any from typing import TextIO @@ -18,6 +19,7 @@ from amplifier_app_cli.session_store import SessionStore from .agent_lanes import AgentLaneViewModel +from .block_render_cache import BlockRenderCache from .bottom_stdout import TranscriptOutput from .bottom_stdout import TranscriptOutputBridge from .clipboard import ImageAttachment @@ -45,6 +47,11 @@ from .repl import SlashCommandCompleter from .terminal_transcript import TerminalTranscript from .text_clipboard import copy_text_to_clipboard +from .transcript_blocks import AnswerBlock +from .transcript_blocks import ToolBlock +from .transcript_blocks import tool_block_from_activity +from .transcript_reflow import TranscriptReflowController +from .ui_events import TranscriptClickAction from .ui_events import UiEventDispatcher @@ -79,6 +86,8 @@ def __init__( self._get_render_profile = bindings.get_render_profile self._get_is_running = bindings.get_is_running self._get_queued_count = bindings.get_queued_count + self._get_queued_preview = bindings.get_queued_preview + self._pop_last_queued = bindings.pop_last_queued self._bundle_name = config.bundle_name self._session_id = config.session_id self._task_tracker = services.task_tracker @@ -96,6 +105,7 @@ def __init__( self._steering_queue = services.steering_queue self._get_task_title = bindings.get_task_title self._on_cycle_mode = bindings.on_cycle_mode + self._on_cycle_permission = bindings.on_cycle_permission self._on_rewind = bindings.on_rewind self._evidence_model = services.evidence_model self._clipboard_detector = ( @@ -140,7 +150,7 @@ def __init__( self._owner_loop: asyncio.AbstractEventLoop | None = None self._terminal_file = sys.stdout self._typed_output = TranscriptOutput( -

Governance/classifier hardening: `_parse_verdict` now tolerates provider thinking blocks (root cause of every tool call failing closed — the evaluator's own reasoning_effort triggered Anthropic extended thinking, and the 1-block contract rejected the response); fail-closed path now logs the swallowed exception and carries bounded detail (StageEvaluation.detail). Still fails closed on genuinely malformed content. Width-reflow scroll-anchor fix: reflow_to_width() preserves the anchor offset WITHIN the anchor span (was snapping to span start, jumping merged raw spans to top on width-only resize — Linux-manifesting, caught in DTU validation). New deterministic unit test. Test-debt cleanup: 20 stale-format failures reconciled to v3 rendering, stale keybinding test ported to the new surface, footer hint cap 3→4 with ctrl-p perms hint added (footer + composer placeholder), goldens regenerated and reviewed. Ctrl-P permission hint completes the ADR-0005 amendment shipped in 9d00f25. Validation evidence: local suite 1951 passed / 0 failed / 0 errors, ruff clean, pyright 0 errors; independently validated in an isolated Linux DTU (full suite 1951/0/0, scripted real-TUI PTY check PASS with ctrl-p hint rendered, width-reflow fix deterministic under tmux 3.7b).
