All gates green; working tree holds exactly the phase's changes for the harness to commit.

## Phase 179 — Final verification report

- **Verified (all 3 tasks already complete in `complete/`)**: repro + CONFIRMED verdict, `asyncio.to_thread` fix, dedicated E2E suite.
- `app/api/sync.py::_run_sync`: both git ops (`clone_or_pull`, `file_commit_dates`) now `await asyncio.to_thread(...)`; phase-134 boundary note + module docstring document worker-thread-runs-to-completion and the A3 DB-calls-stay-on-loop note.
- **Tests / lint / coverage** (full suite 100% green):
  - `uv run pytest tests/integration/test_sync_git_freeze.py -v` → **4 passed** (post-fix probe <1.5 s during 3 s stub)
  - `uv run pytest tests/e2e/test_sync_git_freeze.py -v --no-cov` → **2 passed in 25.65 s in isolation** (wall guard 120 s holds)
  - `uv run pytest --cov=app --cov-report=term-missing` → **4173 passed**, `app/` coverage **99%** (`app/api/sync.py` 100%)
  - `uv run ruff check .` → All checks passed; `uv run pyright` → **0 errors**
- **Completion criteria**: ① integration probe green + verdict (CONFIRMED, mechanism, measured 3.04 s→0.003 s) in docstring — **met**; ② off-loop git ops + boundary/A3 notes — **met**; ③ full suite green, coverage 99% >90%, ruff+pyright clean — **met**; ④ E2E green in isolation (responsive-poll + cancel-during-clone contracts) — **met**; ⑤ atomic commit + move to `complete/` — **harness-owned** (pipeline rule overrides per-phase self-commit; all changes staged-ready in the working tree).
- **Documentation**: full README (1526 l) + AGENTS.md review — phase-179 bullets present and accurate (verified against fixture constants, `.env.example` fully covered by the config reference, pages table matches `app/main.py` shell routes, quick-reference commands/artifacts exist); **consistent — no further changes needed**.
- **Notable**: task-03 pipeline sessions died on context overflow but their harness validation passed; this pass independently re-ran every gate to confirm. No live infra touched; no git index commands run.
- **Next pending phase**: `180_markdown_inline_links_images`.

**Task 01 complete — verdict: CONFIRMED.**
- **`tests/integration/test_sync_git_freeze.py`** (new, test-only; no `app/` change): deterministic in-process repro of the owner's TODO L3 suspicion — 3.0 s blocking stubs on `app.api.sync.clone_or_pull`/`file_commit_dates` (the L233 module names), env-fallback `BOR_GIT_SOURCES` source, real one-commit fixture repo, house `sync_client`/hygiene-fixture patterns, admin/anonymous 403 pins.
- **Verdict recorded in the module docstring**: the sync's synchronous `clone_or_pull → run_git → subprocess.run` runs ON the single uvicorn event loop (`create_task`, no `to_thread`/`create_subprocess_exec` anywhere in `app/`/`scripts/` — grep-verified), stalling the whole HTTP surface. Measured: status probe mid-clone **3.04 s** (≥2.5 floor; slept inside the stub's recorded window), `/api/health` **3.02 s**, idle baseline **0.001 s**, run lands `success` (freeze ≠ failure).
- **Deviation (documented in docstring + S2)**: under `TestClient` the trigger's own `202` is also held ≈3.2 s (the `create_task` body outruns the response dispatch on the shared portal loop), so the trigger POST rides a side thread and the main thread probes — one loop, two concurrent clients, the real uvicorn topology. **Task 02 note**: post-fix both the probe assertion flips to <1.5 s and S2's held-`202` assertion must be flipped/removed (the `to_thread` await yields the loop, freeing the trigger response).
- **Gates (all green)**: `uv run pytest tests/integration/test_sync_git_freeze.py -v` → 3 passed; `uv run pytest --cov=app --cov-report=term-missing` → **4172 passed**, `app/` coverage **99%** (>90%); `uv run ruff check .` → clean; `uv run pyright` → 0 errors.
- **Docs**: no doc impact (test-only task; nothing user-visible changed).
- **Next pending task**: `179_git_clone_server_freeze/02_offloop_git_ops.md` (the `asyncio.to_thread` fix + probe flip).

**Task 02 complete — fix landed, all gates green.**
- `app/api/sync.py::_run_sync`: both per-source git ops now `await asyncio.to_thread(...)` (`clone_or_pull`, `file_commit_dates`); module docstring gained the phase-179 freeze paragraph (TODO L3 CONFIRMED + mechanism + A3 note that the short-lived `SessionLocal`/`effective_sources` calls stay on the loop, deliberately out of scope); the phase-134 boundary comment, `_check_cancelled` and `_run_sync` docstrings now state the worker-thread-runs-to-completion semantics (cancel unblocks the run at the `await`, loop free, `cancelled` terminal unchanged). `check_models`, the local-kind branch and `scripts/git_sync.py` untouched.
- `tests/integration/test_sync_git_freeze.py`: probe flipped to post-fix (`< 1.5 s`), plus pins that the probe lands *inside* the clone window (`finished_at is None`), that the git stub's thread ident differs from the loop's (`to_thread` worker, not the loop), the UI's second poll ~1 s in, the prompt `202`, and a NEW `test_cancel_during_a_clone_lands_cancelled_with_a_free_loop` (202 prompt, `cancelled` terminal inside the still-running clone, `error` null / `detail` `{}`, import never ran). Docstring records CONFIRMED → FIXED with measured numbers: probe 0.0031 s, 2nd poll 0.0027 s, health 0.0033 s, trigger 202 0.026 s, cancel 0.0037 s / terminal 0.0056 s (pre-fix: 3.04 / 3.02 / ~3.2 s).
- Fixed two suites that silently depended on the old synchronous scheduling: `test_sync_api.py` (`test_double_trigger_while_running_returns_409` now `_wait_phase(...)`-polls for `phase=="import"` instead of assuming it; import delay 0.5→1.5 s) and `tests/unit/test_sync_button.py` (new `_pump_until` helper — the loop-thread actions' `Event.wait()` deadlocked once the prelude yielded the loop; 5 action sites + driver docs updated).
- Gates: `uv run pytest tests/integration/test_sync_git_freeze.py -v --no-cov` → **4 passed** (×3 runs, stable); `uv run pytest --cov=app --cov-report=term-missing` → **4173 passed**, `app/` coverage **99%** (>90%; `app/api/sync.py` **100%**); `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors, 0 warnings. E2E spot-checks in isolation: `test_sync_cancel` 3 passed, `test_sync_button` 3 passed, `test_sync_status_freshness` 4 passed, `test_force_push_resync` 2 passed.
- Docs: README "Sync from the UI" gained the "a long clone never freezes the server" bullet + the cancel bullet's worker-thread wording; AGENTS.md gained rule 11 ("Never block the event loop", `asyncio.to_thread`, pointing at the pinned integration test).
- Note: no live-infra touched; no git index/history commands run — all changes left in the working tree.
- Next pending task: `179_git_clone_server_freeze/03_e2e_freeze_contract.md` (the dedicated `tests/e2e/test_sync_git_freeze.py` Playwright suite with the real generated `file://` repo).

**`git` on `PATH` is an E2E prerequisite** (phase 28): the git-source
suites drive real `clone_or_pull` / `file_commit_dates` calls against
generated local `file://` fixture repos. The heaviest is phase 179's
`tests/e2e/test_sync_git_freeze.py`: it builds a ~150 MiB pack-free repo
(30 commits × 5 MiB of seeded pseudo-random bytes) so a fresh

changes only WHO waits: the run's await on the git worker is
unblocked immediately by ``_task.cancel()`` (so the run reaches that
next boundary) and every other request — the 2 s status poll
included — is served while the git thread finishes on its own. The
observable contract is phase 134's, unchanged: stop at the next
boundary, ``cancelled`` terminal, no corruption.
Phase 179 (task 02) — the sync's git operations run OFF the event
loop. Before it, ``clone_or_pull`` and ``file_commit_dates`` were
called as plain synchronous functions from inside ``_run_sync`` — the
coroutine ``POST /api/sync`` spawns with ``asyncio.create_task`` — so
their blocking ``subprocess.run`` (``scripts/git_sync.py``, ``run_git``)
parked the app's SINGLE uvicorn loop thread for the whole git op:
nothing else got scheduled, the ENTIRE HTTP surface stalled (the UI's
2 s ``GET /api/sync/status`` poll included) and the server resumed
only when git returned. That is the owner's ``TODO.md`` L3 suspicion
("a long git clone seems to freeze the server?"), CONFIRMED by the
in-process repro in ``tests/integration/test_sync_git_freeze.py`` — a
3 s stubbed clone made the status probe take ≈ 3.0 s (and
``GET /api/health`` too). Both git steps now go through
``asyncio.to_thread``, so the loop stays free for the whole clone
while the clone/pull and the commit-date walk occupy a worker thread.
Nothing else changes: the pipeline sequence, the error surfaces and
the cancel terminals above are exactly as documented — only the
SCHEDULING of the git calls moved (``scripts/git_sync.py`` itself is
untouched, and it stays the single git-invocation site). Known
BOUNDED non-fix (phase 179 decision A3): the run's short-lived
``SessionLocal()`` / ``effective_sources`` / version-bump calls stay

"""Phase 179 (task 03) E2E (Playwright, mock-only): the owner's suspicion
pinned end to end against the REAL pipeline — no stub anywhere.
``TODO.md`` L3, verbatim: *"A long git clone seems to freeze the server?
Investigate to find out if this is true."*
**VERDICT (task 01): CONFIRMED. → FIXED (task 02).** The sync's git
steps (``app/api/sync.py::_run_sync`` →
``scripts/git_sync.clone_or_pull`` → ``run_git`` → ``subprocess.run``,
plus the ``file_commit_dates`` walk) used to run ON the app's SINGLE
uvicorn event loop, so a long clone parked the loop thread and NOTHING
was served until git returned — not the 2 s ``GET /api/sync/status``
poll the Sources page lives on, not ``GET /api/health``, not the page's
own assets. The server did not fail; it FROZE. Both git steps now run
in a worker thread (``asyncio.to_thread``), and this module is the real
clone proving the fixed contract (task 02's
``tests/integration/test_sync_git_freeze.py`` pins the same contract
with a 3 s stub in-process; here the clone is a real ``git`` subprocess
cloning a real local repo).
**The timing fixture (locked A4): a GENERATED local ``file://`` repo.**
``BIG_COMMITS`` commits, each adding one ``bulk/blob-<k>.md`` of
``BIG_FILE_BYTES`` **seeded pseudo-random** bytes
(``random.Random(k).randbytes`` — deterministic, and near-INCOMPRESSIBLE:
repeated prose would deflate to nothing and the clone would be
instant), each commit replacing the previous bulk blob so the HISTORY
carries the whole ~150 MiB of objects while the checked-out tip stays
two small files. ``notes/sentinel.md`` (the marker
``RESE-FREEZE-SENTINEL-9d3a``) is the tip's file — the KB assertion
target. The source repo is deliberately left **unpacked** (every
mutating git call runs with ``-c gc.auto=0``, and the fixture asserts
the object store is still pack-free): a ``file://`` clone of a
pack-free repo makes git build the pack for the transfer, which is what
a first clone of a fresh repo really costs.
**Calibration (authoring host, 2026-10-14).** Three consecutive FRESH
``git clone file://<fixture>`` runs: **8.68 / 8.71 / 8.74 s** (median
8.7 s) — the A4 bar is ≥ 5 s, so the fixture carries ~1.7× the required
window. The task's starting point ("start ~200 × ~1 MiB") was tuned to
30 × 5 MiB at the same ~150 MiB total: the clone cost of a pack-free
repo is dominated by the delta search over the object set, so fewer,
larger objects keep the build (~7 s) and the clone stable, and the tip
MUST stay small — see the next paragraph.
**Why the tip is two small files:** the clone is the timing fixture,
NOT the mock import. A 150 MiB working tree would push ~75 000 chunks
through the mock embedder and this module into many minutes; the two
tip files keep the import to ~2 s while the git prelude stays the ~9 s
window every assertion measures.
**Timing paragraph.** The clone window (~8.7 s measured) holds ~4 of the
UI's 2 s status polls. The tests poll at that same 2 s cadence
(``page.request``, the owner's poll) and every one must complete in
**< 1.5 s** — ~150× the measured round trip (~10 ms) and ~6× below the
clone itself, so a git op that slides back onto the event loop (task 01
measured ≈ the full clone) can never pass. The asserted minimum prelude
span (4 s) is the pin that the CLONE really was the long pole, and the
minimum poll count inside it (2) is the pin that the polls really landed
inside it — a fixture that got fast fails loudly instead of passing
vacuously.
Run in isolation (DB must be up: ``podman compose up -d db``; ``git`` on
PATH — a documented environment prerequisite, phase 28):
uv run pytest tests/e2e/test_sync_git_freeze.py -v --no-cov
Isolation (the combined-run convention, the ``test_sync_cancel``
pattern): a per-module app on a dedicated port (the conftest session app
is never started in this isolated run), the deterministic mock LLM on
the conftest port (``E2E_REAL_LLM=1`` is SKIPPED — the CLONE, not the
LLM import, is the timing fixture), a dedicated ``BOR_SOURCES_DIR`` for
the checkout, ``BOR_GIT_SOURCES=file://<big repo>`` (the env-fallback
row), and the shared E2E Postgres truncated before AND after every test.
Wall-time guard: the whole module (the fixture build + two full clones
+ page setup) is budgeted at < 120 s and pinned by the module-scoped
``_wall_guard`` (measured ≈ 30 s end to end on the authoring host) — if
the suite drifts, cut ``BIG_COMMITS``, not the guard.
Test → observable mapping (Playwright Mapping Rule):
1. ``test_status_polls_responsive_during_long_clone`` — the owner's
frozen-server check, end to end: a sync whose first action is the
~8.7 s real clone keeps the whole HTTP surface answering. Every
2 s-cadence ``GET /api/sync/status`` issued inside the git prelude
completes in < 1.5 s while the run reports ``running`` with no phase
and no file (the clone/pull prelude), the page's OWN poll loop keeps
landing 200s (≥ 2 inside the prelude — a frozen loop starves it), the
Sources page stays in its live "Syncing…" state with the Cancel
control still available and NO error surface, and the run lands
``success`` with the sentinel document in the KB (the real clone's
content, reachable through the drill-down catalog).
2. ``test_cancel_during_clone_reaches_terminal`` — phase 134's
cooperative cancel under the off-loop scheduling: with the checkout
deleted (so the run re-clones — a long git phase again), the UI's
Cancel click round-trips in < 1.5 s and the run settles into the
``cancelled`` terminal (``error: null``, ``detail: {}``, no import
ever started) WHILE the abandoned git worker is still writing its
clone (the checkout's worktree is still absent) — the status polls
issued during that window all complete in < 1.5 s, which is
decision A2's observable: the thread runs to completion, the loop
serves everyone else. The UI settles to the neutral "Sync cancelled"
(retry-ready button, no banner, no modal) and the KB stays empty for
the source (the abandoned clone's result is never imported).

"""Integration: phase 179 — the owner's suspicion (``TODO.md`` L3,
verbatim): *"A long git clone seems to freeze the server? Investigate
to find out if this is true."*
**VERDICT (task 01): CONFIRMED. → FIXED (phase 179 task 02,
``asyncio.to_thread``).** A long ``git clone`` during a sync DID block
the app's event loop, and while it was blocked the ENTIRE HTTP surface
was stalled — including ``GET /api/sync/status``, the endpoint the UI
polls every 2 s, and even the dependency-free ``GET /api/health``. The
server did not fail; it FROZE — and the UI's status poll, the one
request that must stay live to watch a long sync, was among the
victims. Both git steps now run in a worker thread, and the probes
below are flipped to pin the server staying responsive.
**Mechanism (pre-fix, no ``to_thread`` anywhere).** ``POST /api/sync``
spawns the run with ``asyncio.create_task(_run_sync())``
(``app/api/sync.py``) — the coroutine runs on the app's SINGLE uvicorn
event loop. ``_run_sync`` called the per-source git steps as plain
synchronous calls — ``root = clone_or_pull(...)`` →
``scripts/git_sync.py::clone_or_pull`` → ``run_git`` →
``subprocess.run``. There was no ``asyncio.to_thread`` and no
``create_subprocess_exec`` anywhere in ``app/`` or ``scripts/``, so a
long clone parked the loop thread itself: no other coroutine —
including the ASGI dispatch of ANY incoming request, even sync-``def``
threadpool endpoints like ``/api/health`` — could be scheduled until
git returned.
**Measured PRE-fix (task 01, 3.0 s stubbed clone).** The
``GET /api/sync/status`` probe issued into the middle of the clone took
**≈3.0 s** (measured 3.04 s — the full remainder of the git op plus the
runner's yield-less tail); the ``GET /api/health`` probe in the same
window took **≈3.0 s** (measured 3.02 s — any endpoint on the loop
stalls); the trigger's own ``202`` was held ≈ 3.2 s. Idle, the same
endpoints answer in **milliseconds** (measured ≈ 0.001 s).
**Measured POST-fix (task 02, the same 3.0 s stubbed clone, the same
scenario).** The status probe issued into the middle of the clone took
**≈ 0.003 s** (0.0031 s), the second poll one second later the same
(0.0027 s), ``GET /api/health`` **≈ 0.003 s** (0.0033 s), the trigger's
``202`` **≈ 0.026 s**, and a ``POST /api/sync/cancel`` issued mid-clone
**≈ 0.004 s** with the ``cancelled`` terminal landing **≈ 0.006 s**
later — still INSIDE the abandoned clone's sleep, which is the proof
that the run no longer waits for the git worker while the worker itself
finishes on its own. The stub records the thread it ran on: pre-fix it
was the event-loop thread (identical idents), post-fix it is an
``asyncio`` worker thread (different ident) — asserted, so a git op that
slides back onto the loop fails this file even on a machine fast enough
to hide the latency.
**What phase 179 does NOT change:** the pipeline sequence, the run's
terminals (the stubbed run still lands ``success`` with the same
``detail``), and the phase-134 cooperative-cancel contract — a cancel
registered while a git op is in flight stops the run at the next
boundary (or right at the ``to_thread`` await, which is now the
common case), lands the ``cancelled`` terminal with ``error`` null and
``detail`` empty, and never resumes the pipeline with the abandoned
clone's result. Python threads are not interruptible: the git worker
runs its ``subprocess`` to completion, but the EVENT LOOP is free the
whole time.
**TestClient mechanics (why the trigger still rides a side thread).**
The shared app loop here is anyio's ``BlockingPortal`` thread. Firing
``POST /api/sync`` from the test thread would make the mid-clone probe
unfalsifiable — on a regressed (blocking) run the POST itself would be
held for the whole clone and only return once the git window had
CLOSED, so a later probe would be served instantly and pass on a frozen
server. With the trigger on its own thread the MAIN thread is a free
second client — the UI's 2 s poll — and the probe provably lands
mid-clone (the stub's ``finished_at is None`` pin). The trigger's own
latency is asserted too, in the post-fix direction (prompt, not held).
**The repro is deterministic and in-process:**
``app.api.sync.clone_or_pull`` / ``app.api.sync.file_commit_dates`` (the
module-level names imported in ``app/api/sync.py`` — patching the
``scripts.git_sync`` originals would NOT affect the runner) are
monkeypatched with stubs that record a ``time.monotonic()`` start/end,
the thread they ran on, and ``time.sleep(3.0)`` — the stub is a PLAIN
SYNC function, exactly like the real ``clone_or_pull``, because the
point under test is WHERE it runs. The git source rides the env fallback
(``BOR_GIT_SOURCES=file://<tmp repo>``, a fresh ``Settings`` on the
resolver's module — the dev ``.env`` never leaks in); the tmp repo is a
real one-commit git repo (the ``test_sync_cancel._git`` helper shape)
although the stub never actually clones it.
House patterns (``test_sync_api.py``): the ``sync_client`` fixture is a
**context-managed** ``TestClient`` — one app event loop across requests,
exactly how the app runs under uvicorn (without the context manager a
fresh loop per request would cancel the background task); the module
status/task/cancel-event reset + the ``git_sources`` / ``sources_meta``
/ ``folder_summaries`` global-state hygiene fixtures around every test;
the import / overview / folder-summary layers monkeypatched in
``app.api.sync`` so only the CLONE is the timing fixture.
