`on.pull_request.branches` filters on the *base* branch, not the head. With it pinned to `main`, only a pull request merging directly into `main` ran CI -- every stacked pull request, whose base is the branch below it in the stack, got no test, lint or mypy run at all and showed nothing but the Mergify checks. Drop the filter so CI runs for every pull request regardless of base. Change-Id: I1c211a106a57b9f4986bec4b76c0680c1a0f1b61
`__radd__` was annotated `other: wait_base`, which is the one type it can never receive: `wait_base.__add__` always succeeds, so Python never falls back to the reflected operator for two wait strategies. The only caller is `sum()`, which seeds its accumulator with the int 0 — hence the `type: ignore[comparison-overlap]` on `other == 0`, and the dead `return self` branch behind it that `--warn-unreachable` flags. Annotate the parameter as `int` and return `NotImplemented` for a non-zero left operand, so `5 + wait_fixed(1)` raises `TypeError` at the addition rather than building a `wait_combine` that explodes later when called. With the signature corrected, mypy infers `sum([...])` over wait strategies on its own, so four `type: ignore[list-item]` comments in `test_wait_arbitrary_sum` are no longer needed.

`strict = true` is a curated subset, not every check mypy has. These five error codes and three flags are all off under `strict` and all report zero errors on the current tree, so turning them on costs nothing today and catches regressions from here on: - `warn_unreachable` -- dead branches, which are usually a wrong annotation rather than dead code (see the `wait_base.__radd__` fix below this commit) - `disallow_any_unimported` -- silent `Any` leaking in from untyped deps - `extra_checks` -- unsafely overlapping operator signatures, among others - `ignore-without-code` -- keeps `type: ignore` comments specific - `redundant-expr`, `truthy-iterable`, `unused-awaitable`, `exhaustive-match` Deliberately left off: `disallow_any_expr` (655 errors -- unusable for a decorator library) and `disallow_any_decorated` (63 errors, all inherent to `@retry` wrapping untyped test helpers).

`truthy-bool` reports objects tested for truthiness that implement neither `__bool__` nor `__len__`, and so can only ever be true. Three sites: `BaseRetrying._run_wait` and `AsyncRetrying._run_wait` both guarded the wait call with `if self.wait:`. `wait` is typed `WaitBaseT` and defaults to a `wait_none()` instance, so it is never falsy and the `sleep = 0.0` branch has been dead since 17aefd9 -- a leftover from when the surrounding code still used `if self.after is not None:` style guards. Call `self.wait` unconditionally. `if tornado:` guarded the optional import in two places. mypy only ever sees the `try` branch, so it resolves the name to the module and reads the test as always-true. Compute `_HAS_TORNADO` once and branch on that instead; this also keeps `tornado.gen` fully typed, which annotating the name as `ModuleType | None` would have thrown away.

`mutable-override` rejects narrowing a mutable attribute in a subclass:
`RetryAction.REPR_FIELDS = ("sleep",)` inferred `tuple[str]` against the
base's `Sequence[str]`, and `NAME = "retry"` inferred `str` against
`str | None`. Both are unsound in general -- code holding a `BaseAction`
could assign a longer sequence or `None` through the base type.
`BaseAction`'s docstring already calls these class variables, so mark them
`ClassVar` and repeat the base annotation on the override. This documents
the extension point for subclasses outside tenacity too, which hit the
same error when they type check strictly.
