Recovered child-session instructions describe the earlier human
authorization to remove EMA's eager Numba signature while retaining
`jit(nopython=True, nogil=True)`, verify defaults, and finish the commit
plan without staging or committing. This is recovered context, not a
verbatim quote of the earlier human authorization.

## Response

> `git diff HEAD~1..HEAD -- piker/fsp/_momo.py`

Removed EMA's eager Numba signature and now-unused Numba type imports.
Retained nopython/nogil compilation, the numerical kernel, historical
comments, and pre-existing staged and unstaged edits.

> `git diff HEAD~1..HEAD -- tests/test_fsp_momo.py`

Added production-dispatcher regressions for omitted positional and
keyword arguments, explicit None and numeric parameters, and the
previously corrected one-sample continuation. Expected outputs are
hand-computed recurrences, rather than the Python implementation.

Before the fix, the first case failed with:

```text
TypeError: No matching definition for argument type(s)
array(float64, 1d, C), omitted(default=None), omitted(default=None)
```

After the fix, the focused run outside the socket-restricted sandbox
reported:

```text
38 passed in 0.66s
```

Ruff passed for the modified momentum module and new regression file.
Combined-worktree results do not attest to isolated commit boundaries.
