Final verification pass complete — everything independently re-verified green. Report:

**Phase 108 — History wire check (final verification pass; verdict: NO BUG, tests-only per D13)**

- Verified all 3 tasks complete in `.agents/phases/complete/108_history_wire_check/`; re-ran every pin and gate myself
- Layer 1 (unit): 2 owner-shape pins in `tests/unit/test_history.py` (2-turn keep-whole + A4 thinking mapping) — pass
- Layer 2 (integration): `test_endpoint_two_turn_history_reaches_the_llm` — captured LLM request = `[system, user Q1, assistant R1, user Q2]`, `history_msgs=2` — pass
- Layer 3 (E2E): `tests/e2e/test_history_wire_check.py` — owner's verbatim 3-message scenario, echo byte-exact (T2: `2 prior messages`+R1 tail; T3: `4 prior messages`+R2 tail) — pass
- `VERDICT.md` present in phase dir: layer outcomes + "no bug — model behavior/user error" + pin names

**Gates (exact results)**
- `uv run pytest --cov=app --cov-report=term-missing` → 2305 passed, TOTAL **99%** (>90%)
- `uv run pytest tests/e2e/test_history_wire_check.py -v --no-cov` → 2 passed (isolation, DB up)
- `uv run pytest tests/e2e/test_llm_history.py -v --no-cov` (phase-74 regression) → 3 passed
- `uv run ruff check .` → clean; `uv run pyright` → 0 errors

**Completion criteria:** all six met — no defects found; diff scoped to `tests/**`, `VERDICT.md`, `.agents/phases/**`, `.agents/reports/**` (no `app/`/`frontend/` changes, consistent with no-bug verdict). Per executor rules, no git commit made — left for the harness.

**Next pending phase:** `109_turn_progress_loader`

# Phase 108 Verdict — History wire check (TODO.md L4)
**Verdict: NO BUG.** The follow-up history wire is proven complete at all
three layers, for the owner's exact scenario, byte-exact via the phase-74
`echo my history` oracle (D14 — no new marker). The reported instance
("What did I just ask you?" → "This is the first question you've asked")
was **model behavior / user error**, exactly the owner's own hypothesis
("Just check if there's a bug, there may not be"). No `app/` or
`frontend/` changes were needed — the phase ships tests-only (D13).
## Layer outcomes
| Layer | What it isolates | Outcome | Pins (evidence) |
|-------|------------------|---------|-----------------|
| 1 — unit: the trimmer | `history_to_messages` (`app/rag/prompts.py`) | **PASS** — the owner's 2-turn history (Q1 "What is my name?" / R1 "Your name is Reese.") under the DEFAULT budgets (40 turns / 24 000 chars, no overrides) survives whole: chronological, roles mapped, thinking → `reasoning_content` only when non-empty (A4) | `tests/unit/test_history.py::test_short_two_turn_history_kept_whole_and_chronological`, `::test_two_turn_history_thinking_mapping` |
| 2 — integration: the endpoint | `POST /api/chat` splice, both branches (`app/api/chat.py`) | **PASS** — the SAME 2-turn history through the real endpoint (follow-up "What did I just ask you?") makes the LLM request exactly `[system, user Q1, assistant R1, user Q2]`; SSE `done`; log line carries `history_msgs=2`. Branch-agnostic by design (phase 74 pinned the splice on both branches) | `tests/integration/test_chat_api.py::test_endpoint_two_turn_history_reaches_the_llm` |
| 3 — E2E: the full browser wire | client record → `conversation.slice(0, -1)` → body → LLM (`frontend/assets/app.js`) | **PASS** — the owner's verbatim 3-message scenario in a real browser: T2's echo = `history: 2 prior messages` + R1's exact 24-char tail; T3's echo = `history: 4 prior messages` + R2's exact tail (tails read from the persisted `bor.chat.v1` record — what the client saved is what it sends). The missing-first-turn bug would render T2 as `0 prior messages` / `last answer tail: none`; it does not | `tests/e2e/test_history_wire_check.py::test_cold_start_echo_shows_no_phantom_history`, `::test_owner_scenario_three_turns_carry_the_full_prior_history` |
## Why "no bug" is sound
- Layers 1 and 2 prove the server drops nothing: a short history is
orders of magnitude under both budgets, and the captured LLM request on
the real endpoint carries the complete prior exchange, chronological.
- Layer 3 proves the client sends what it saved: the echo's `N prior
messages` count and `last answer tail` are computed by the mock from
the request itself, and both matches hold byte-exactly for turns 2 and 3.
- The deterministic mock leaves no room for "the model forgot" at the
wire level — the model (turbo) simply receives the full history and
occasionally mis-reports it. The owner's third message working correctly
is consistent with model non-determinism over a complete wire.
## The pins stay as the permanent guard
A future regression that drops the first turn — in the trimmer, the
endpoint splice, or the client's record→history mapping (including the
phase-49 retry / phase-53 stale-regen pop paths) — fails layer 1, 2, or 3
immediately.

Task 01 complete — all gates green, no `app/` changes needed.
**Implemented**
- Layer 1 (unit): 2 new owner-shape pins in `tests/unit/test_history.py` — `test_short_two_turn_history_kept_whole_and_chronological` (owner's exact Q1/R1 under default 40-turn/24k budgets → kept whole, chronological, roles mapped) and `test_two_turn_history_thinking_mapping` (non-empty `thinking` → `reasoning_content`; empty/absent → key ABSENT, A4).
- Layer 2 (integration): `test_endpoint_two_turn_history_reaches_the_llm` in `tests/integration/test_chat_api.py` (next to the phase-74 block) — real `POST /api/chat` with the owner's 2-turn history + "What did I just ask you?"; SSE completes (`done`), captured LLM request is exactly `[system, user Q1, assistant R1, user Q2]`, log line carries `history_msgs=2`. Branch-agnostic by design (phase 74 pinned the splice on both branches); uses the file's standard `seeded_kb` idiom, noted in the docstring.
**Verdict inputs for task 03**
- Layer 1: PASS (no bug in `history_to_messages`) · Layer 2: PASS (no bug in endpoint splice) — server wire proven complete; tests-only, no fix.
**Results**
- `uv run pytest tests/unit/test_history.py tests/integration/test_chat_api.py -v` → 56 passed
- `uv run pytest --cov=app --cov-report=term-missing` → 2305 passed, TOTAL **99%** (>90%)
- `uv run ruff check . && uv run pyright` → clean / 0 errors
**Next pending task:** `02_client_e2e_owner_scenario.md` (layer 3 — new E2E `tests/e2e/test_history_wire_check.py`).

**Task 02 complete — layer 3 (client wire) GREEN, no fix needed.**
- Implemented `tests/e2e/test_history_wire_check.py` (new, 2 tests) — phase-74 fixture/app-server/auth idiom, localStorage `bor.chat.v1` record reads for the expected tails:
- `test_cold_start_echo_shows_no_phantom_history` — first message echoes `0 prior messages` / `last answer tail: none` / `thinking: no`
- `test_owner_scenario_three_turns_carry_the_full_prior_history` — owner's verbatim Q1/Q2/Q3 (marker appended to T2/T3); T2 echo = `2 prior messages` + R1's exact 24-char tail, T3 echo = `4 prior messages` + R2's exact tail — the regression pin for the owner's missing-first-turn symptom
- Layer-3 outcome: **PASS on first run** — the full browser wire (record → `slice(0,-1)` → body → LLM) carries the complete prior conversation; no client defect found (with layers 1-2 already green → basis for "no bug" verdict for task 03's VERDICT.md)
- Tests: `uv run pytest tests/e2e/test_history_wire_check.py -v --no-cov` → **2 passed** (isolation, DB up)
- Regression: `uv run pytest tests/e2e/test_llm_history.py -v --no-cov` → **3 passed**; `uv run pytest tests/unit/test_history.py` → 18 passed
- Full suite: `uv run pytest --cov=app --cov-report=term-missing` → all passed, **TOTAL 99%** (>90% gate)
- Lint/types: `uv run ruff check . && uv run pyright` → clean (0 errors)
- No `app/` changes; no commits made (left in working tree for the harness)
- Next pending task: `03_verdict_fix_or_pin.md` (VERDICT.md + final gate + commit)

**Phase 108 task 03 complete — verdict: NO BUG (tests-only, no code fix needed).**
- Wrote `.agents/phases/todo/108_history_wire_check/VERDICT.md`: all three layers PASS — the history wire is proven complete at the trimmer, the endpoint, and the full browser wire; the owner's reported instance was model behavior/user error. Pins named as the permanent guard.
- Verified tasks 01-02 work (diffs + code review): unit pins `test_short_two_turn_history_kept_whole_and_chronological`, `test_two_turn_history_thinking_mapping`; integration pin `test_endpoint_two_turn_history_reaches_the_llm` (LLM request = `[system, user Q1, assistant R1, user Q2]`); E2E `test_history_wire_check.py` (owner's verbatim 3-message scenario, byte-exact echoes: T2 `2 prior messages` + R1 tail, T3 `4 prior messages` + R2 tail).
**Gate results (all re-run by me this session, DB up):**
- `uv run pytest --cov=app --cov-report=term-missing` (superset of `uv run pytest`; testpaths = unit+integration) → exit 0, no failures, **TOTAL 99%** (>90%)
- `uv run pytest tests/e2e/test_history_wire_check.py -v --no-cov` → **2 passed** in isolation
- `uv run pytest tests/e2e/test_llm_history.py -v --no-cov` (phase-74 regression) → **3 passed** in isolation
- `uv run ruff check . && uv run pyright` → **All checks passed!** / **0 errors**
- Scope check: diff limited to `tests/**`, `VERDICT.md`, `.agents/phases/**` (harness-moved task files) — no `app/`/`frontend/` changes
**Deviations:** no `git add`/commit made and no phase-dir move — harness protocol overrides task 03's commit/move steps (matches phase 107's recorded precedent); all changes left in the working tree. No defects found in prior work.
**Next pending:** phase `109_turn_progress_loader` (first task in `.agents/phases/todo/109_turn_progress_loader/`).

"""Phase 108 (task 02) E2E (Playwright): the owner's exact follow-up
scenario, byte-exact on the FULL browser wire.
Story: n/a — owner bug report 2026-09-16 (TODO.md L4): "I've noticed at
least one instance where a follow-up chat is missing the first message
and response as context. So if I ask 'What is my name' and then 'What
did I just ask you?' the model responds 'This is the first question
you've asked'. But if I send a third message 'What was the previous
question' the model responds correctly … Just check if there's a bug,
there may not be."
This is LAYER 3 of the phase's three-layer wire check (D13): layers 1-2
(the trimmer + the endpoint, task 01) prove the SERVER; this file proves
the CLIENT — the localStorage ``bor.chat.v1`` record →
``conversation.slice(0, -1)`` mapping → request body → the LLM — with
the owner's exact 3-message scenario. The oracle is the phase-74
``echo my history`` marker, reused unmodified (D14): the mock answers
``history: N prior messages; last answer tail: <last 24 chars of the
most recent prior assistant message, or "none">; thinking: yes|no`` —
N = non-system messages before the LAST user message (the current
question excluded). The marker is checked BEFORE the mock's
DEFLECT_MODE branch, so the echo fires on BOTH turn branches — the
owner's questions are personal, the gate branch is irrelevant to the
pin, and no branch is asserted.
The expected tails come from the ``bor.chat.v1`` record the client
persisted (the SAME array task 02's mapping sends as ``history`` —
what the record shows IS what the model received), read AFTER each turn
persists, exactly the ``test_llm_history.py`` idiom.
Run in isolation (DB must be up: ``podman compose up -d db``):
uv run pytest tests/e2e/test_history_wire_check.py -v --no-cov
Each test pins:
* ``test_cold_start_echo_shows_no_phantom_history`` — a FRESH
conversation: the first message's echo shows ``0 prior messages`` /
``last answer tail: none`` / ``thinking: no`` — no phantom prior
turns leak into the first turn's history block.
* ``test_owner_scenario_three_turns_carry_the_full_prior_history`` —
the owner's exact 3 messages (turns 2-3 carry the echo marker, the
owner's words preserved verbatim as the prefix):
T1 ``What is my name?`` → R1 (read raw from the record); T2
``What did I just ask you? echo my history`` → the echo must show
``2 prior messages`` + R1's exact 24-char tail; T3 ``What was the
previous question? echo my history`` → ``4 prior messages`` + R2's
exact tail. THE regression pin for the owner's symptom: the missing-
first-turn bug renders T2's echo as ``0 prior messages`` /
``last answer tail: none``.
No thinking is ever triggered (none of the owner's questions carries
the ``think out loud`` marker), so every echo reads
``thinking: no``.
