phase: 192_verbatim_inline_midturn
Phase 192 — final verification pass complete. - **Verified (all 4 tasks already complete):** additive `verbatim_block` SSE frame (`VerbatimBlockPiece` → `ChatVerbatimBlockEvent` → chat dispatch, after the round's `tool`/`tool_result`, before the next round); `hydrateVerbatimNow` matched-only mid-turn pass + app.js branch; `dropPlacedTwin` per-locator done/restore dedupe; the dedicated E2E suite. - **Root cause of the rejected attempt:** my own concurrent background `pytest` run deadlocked the harness validation run on the shared Postgres (`psycopg.errors.DeadlockDetected`). No code defect — re-ran every gate **exclusively**. - `uv run pytest -q --cov=app --cov-report=term-missing` → **exit 0**, `TOTAL 7181 16 99%` (>90%) - `uv run pytest tests/e2e/test_verbatim_inline_midturn.py --no-cov` → **6 passed** (isolated) - `uv run pytest tests/e2e/test_verbatim_show_text.py tests/e2e/test_chat_history.py --no-cov` → **18 passed** (`test_chat_history.py` byte-unedited; the phase-182 suite's "no eighth type" pin was tightened, not loosened, to seven + `verbatim_block` with frame-order asserts) - `uv run ruff check .` → All checks passed (exit 0) · `uv run pyright` → **0 errors** - **Completion criteria:** single frame per success + zero per refusal ✅ · `BOR_ANSWER_TEXT=0` wire byte-identical (integration spelled baseline + E2E App B) ✅ · fence hydrates in place / unfenced lands at the call moment, before `done` ✅ · append+fence → 1 panel, two ranges → 2 panels ✅ · restore 1 panel/locator, `done.answer_text` + record key + `verbatim_blocks=N` unchanged ✅ · suite green, coverage 99%, lint/types clean ✅ · no-show_text turn byte-identical ✅ · commit → left to the harness (no git index/history commands run). - **Docs:** README reviewed line-by-line (2399 lines) + AGENTS.md in full; mechanically verified all 86 `BOR_*` settings, every `.env.example` var, table defaults, internal anchors (0 broken), ports 8123/8901, tree depth 1–8, pagination 25/1–100, 17 palette colors, `0029`/`0030` migrations, and every cited test file. Fixed 1 inconsistency: the verbatim "Parity" bullet claimed the live turn/reload/shared page share "the same three globals" — now names the settle-path trio and states that `hydrateVerbatimNow` is the ONE chat-only addition (a shared page has no stream). - **Notable:** `run_agent`'s four repeated piece unions were collapsed into the ONE exported `AgentPiece` alias, so a future piece type is spelled in one place; `test_frontend_edit_message.py`'s `runTurn` byte-pin was regenerated, not weakened. - **Next pending phase:** `193_sync_remaining_count`.

|

#: on screen while the answer has NOT streamed a single token, so

#: "the panel landed mid-turn" is pinned by the DOM itself, not by a poll.

#: Arms, discriminated by markers in the question (all disjoint from every

#: other trigger, ordering convention intact):
|
||||
#
|
||||
#: * default — no fence anywhere: the mid-turn block is APPENDED at the
|

#: answer position (``appendUnlocatedVerbatim``).
|
||||
#: * ``MIDTURN_FENCE_BEFORE_MARKER`` — the fence rides round 1, so the
|
||||
#: placeholder EXISTS when the frame lands: the mid-turn
|
||||
#: ``hydrateVerbatimNow`` pass resolves it IN PLACE.
|
||||
#: * ``MIDTURN_FENCE_AFTER_MARKER`` — the fence rides the final answer
|
||||
#: (the realistic shape: the model quotes after the call), so the
|
||||
#: mid-turn panel is appended and the ``done`` pass re-homes it onto
|
||||
#: the fence and drops the twin (task 03's ``dropPlacedTwin``).
