+# Known full-suite failures
+
+`python -m pytest -q` does not come back clean on every machine, and it never
+has. Without a list of which failures are expected, a first local run is
+uninterpretable: you cannot tell "you broke something" from "you are on a Mac",
+so the usual result is either chasing a non-bug or ignoring a real one.
+
+This is that list. It is a record of observation, not a permission slip: a test
+here is still a test that does not pass, and the three that remain below are
+all still worth someone's time.
+
+Last measured: `lab @ c499c01b` plus the fixes in this change, macOS 15 on
+Apple Silicon, Python 3.11, with the **default** `$TMPDIR` — see the socket
+entry below for why that qualifier is load-bearing.
+
+```
+3 failed, 10658 passed, 6 skipped
+```
+
+## Get the prerequisites right first
+
+Most "surprise" failures are a missing dependency rather than anything in this
+file. A clean run needs all of:
+
+```bash
+python3.11 -m venv venv
+./venv/bin/python -m pip install -r requirements.txt
+npm ci                              # the browser tests shell out to node
+npx playwright install chromium     # ~30 tests drive a real browser
+mkdir -p data                       # SQLite lives at ./data/app.db
+```
+
+plus `ffmpeg` on `PATH` for the media tests.
+
+If you already have a ChromaDB running, point `CHROMADB_PORT` at a closed port
+for the run. The client reaches Chroma over HTTP regardless of the data
+directory, so a test run will otherwise attach to whatever store is listening,
+including one holding real data.
+
+Miss `npm ci` and roughly 36 browser tests fail on `Cannot find package
+'playwright'`. That is not a regression, it is the missing install.
+
+## The three that remain, and the seven that no longer do
+
+### Test bugs: comparing an unresolved path against a resolved one
+
+Three failures compared an unresolved `/tmp` path against a resolved
+`/private/tmp` one, and are fixed rather than listed:
+
+- `tests/test_code_nav_tools.py` (two tests) built a fixture under
+  `tempfile.mkdtemp(dir="/tmp")` and compared it against the path the code
+  reports, which it resolves.
+- `tests/test_workspace_confine.py::test_glob_confined_e2e` mixed
+  `os.path.realpath(ws)` with an unresolved secret directory, so `relpath`
+  produced `../../../../tmp/<absolute path>` and the assertion that the
+  absolute path was absent matched it as a substring.
+
+Both now resolve consistently. They are recorded here because the shape recurs:
+on macOS, mixing a resolved and an unresolved temp path is a test bug that
+looks like a platform failure.
+
+### Test bugs: a temp path too long to bind a socket to
+
+Four more, same family, invisible unless `$TMPDIR` is long enough:
+
+- `tests/test_shell_routes.py::TestHostDockerAccess` (three tests)
+- `tests/test_cookbook_docker_access.py::test_container_opt_in_with_unix_socket_is_allowed`
+
+```
+OSError: AF_UNIX path too long
+```
+
+Each bound an `AF_UNIX` socket at `tmp_path / "docker.sock"`. macOS gives
+`sun_path` 104 bytes including the terminator, and pytest's `tmp_path` is
+rooted at `$TMPDIR`, which on a stock Mac is a 49-character
+`/var/folders/<2>/<30>/T/`. Add `pytest-of-<user>/pytest-<n>/` and the test's
+own name and the bind path is 115 bytes before the filename.
+
+This is why the counts above depend on where you run from: under a shortened
+`$TMPDIR` the path lands at 103 and the tests pass, and it tips over the moment
+pytest's run counter reaches two digits. Linux allows 108 bytes and roots
+`$TMPDIR` at `/tmp`, so it never bites there and CI stays green.
+
+They now bind through `tests/helpers/unix_sockets.bound_unix_socket`, which
+puts the socket under a short directory. **Measure with the default `$TMPDIR`**
+— `env -u TMPDIR` or an explicit `/var/folders/...` — or this whole file
+records a run nobody else has.
+
+### Optional dependency: ffmpeg without a WebP encoder
+
+- `tests/test_inspect_media_tool.py::test_inspect_media_exports_final_decodable_frame_at_exact_duration`
+
+```
+ffmpeg still extraction failed: Automatic encoder selection failed ...
+Error opening output files: Encoder not found
+```
+
+The test asks ffmpeg for a `.webp` still and asserts `exit_code == 0`. WebP
+encoding is a build option, and Homebrew's ffmpeg does not always carry it. CI
+installs a build that does, which is why this is green there.
+
+**Needs a decision**: skip when the encoder is absent, or fall back to PNG. The
+current shape asserts success from a codec that is not guaranteed present.
+
+### Environmental: real sockets
+
+- `tests/test_integration_api_call_ssrf.py::test_real_socket_falls_back_from_dead_first_to_live_second`
+
+```
+httpcore.ConnectTimeout / httpx.ConnectTimeout
+```
+
+Opens real sockets and depends on a connection to a dead address being refused
+quickly rather than hanging. Sandboxed and restricted-network machines time out
+instead. Genuinely environmental.
+
+### Unexplained: rich-text colour contrast
+
+- `tests/test_document_rich_color_reset_and_contrast.py::test_rich_colors_follow_theme_and_undo_as_one_edit`
+
+A Playwright run times out waiting for `#doc-email-richbody p` to contain a
+`span` after a colour is applied.
+
+**This one is not flaky.** Three consecutive runs failed identically, each at
+about 31 seconds. It was previously written off as timing noise and that was
+wrong. The cause is not established, and until it is, treat it as a possible
+real defect in the rich-text colour path rather than a platform artifact.
+
+## Keeping this current
+
+Re-measure on a clean checkout of `lab` with the prerequisites above, and
+update the header revision, the counts and any entry that changed. A failure
+that appears and is not listed here is a regression until shown otherwise.

+"""Module-graph coverage for the split email library.
+
+``specs/frontend.md`` records that this frontend has "no build-time type
+checking, module graph validation, or script-order validation". That is
+tolerable for a single 11k-line file and not tolerable for a package: splitting
+``emailLibrary.js`` into modules that import each other adds three failure modes
+nothing else here would catch.
+
+1. The compatibility wrapper at ``static/js/emailLibrary.js`` drops an export.
+   Five call sites import that path; a missing name is ``undefined`` at call
+   time, not an error at load time, so the panel just stops responding.
+2. A module in the package fails to evaluate — a stale relative specifier after
+   a move, or a temporal-dead-zone read across an import cycle. The package has
+   cycles by construction: extracted modules call back into ``index.js`` from
+   event handlers. That is safe for hoisted function declarations and *not* safe
+   for a ``const`` read while the graph is still evaluating, and which one you
+   wrote is invisible in a diff.
+3. A new module is missing from the ``sw.js`` precache, so the panel that works
+   online cannot open offline.
+
+The first and third are read off the source. The second needs a real module
+loader, so it runs in a browser: each module is imported *on its own*, in a
+fresh page, because entering the cycle at a submodule rather than at the entry
+module is the order that exposes a dead-zone read.
