paceENSDF returns intensity at state[9] (percent), not state[8] (ENSDF
normalization field, ~1.0 for all branches). This was causing ~50/50
split for Tc99 instead of the correct 99.9984%/0.0016%.
Branch intensity, endpoint, and transition are constant per branch and
already documented in the CSV header. No need to repeat them as columns
for every energy row.
- Cross out B3 in TODO.md with completion details
- Export BranchConfig in __init__.py public API
- Update README to mention per-branch transition types and intensity cutoff
- Add --intensity-cutoff CLI option to filter negligible branches
- Fetch DecayInfo from paceENSDF and construct SpectrumConfig with
branches including per-branch transition types
- Normalize branch intensities to sum to 1.0, filter by cutoff
- Display branch info in dry-run output and logging
- Add intensity_cutoff to SpectrumConfig
- Add transition_type field to BranchInfo and extract per-branch
forbiddenness codes from paceENSDF (not defaulting all to 'A')
- Fix _multi_branch_call to use np.maximum instead of np.where mask
so branches smoothly approach zero at endpoint
- Rewrite _plot_multi_branch_spectra and _plot_multi_branch_debug Panel 1
to plot raw (un-normalized) branch contributions so total = sum of branches
- Remove independent unit-area normalization that made small branches
appear larger than total
- Add commit hash (6 chars) and UTC timestamp to all plots via text boxes
- Add nuclear data header (nuclide, endpoint, transition, corrections) to plots
- Two display modes:
- DEBUG (-vv): 4-panel debug view with all correction factors
- Normal (default): single spectrum plot with nuclear data header
- CLI: --plot now passes show_components=(args.verbose >= 2)
- Remove --mode, --transition-type, and --decay-index CLI flags
(parameters now come from ENSDF data or custom JSON input)
- Clarify energy units in all CLI help text (MeV throughout, keV for detector params)
- Enhance logging verbosity:
- -v (INFO): shows source, component initialization, workflow steps
- -vv (DEBUG): shows detailed internals of all spectrum components
(parameters, evaluation counts, input/output ranges)
- Improve CSV headers with element notation (e.g. Tc99 -> Ru99)
- Add CONVENTIONS.md documenting energy unit and logging conventions
- Update TODO.md with completion status
- Remove empty beta_spectrum/components/recoil.py (0-line stub)
- Remove recoil.py from README.md project tree and components table
- Update TODO.md: replace specific recoil section with generic 'Additional
Corrections' deferred item, update Current Status to 0.3.0 with actual
implementation list, mark A4 as complete, set A3 as next step

- Run black and ruff for formatting and linting
- Add proper type annotations to all source files
- Fix return types for numpy operations (np.asarray with dtype=np.float64)

- Add create_config_from_source() unified interface for both sources
- Add bs_pnpi CLI with --nuclide, --input, --output, --plot, and detector options
- Add 23 comprehensive tests for nuclear_data module
- Add sample JSON input file
- Update __init__.py and pyproject.toml with new exports and entry point
- Add paceENSDF as optional dependency
Add CurveFitter with scipy least_squares, configurable loss functions
(soft_l1, huber, cauchy), profile likelihood, confidence intervals, and
goodness-of-fit metrics. Add CWExtractor for extracting shape factors
from beta spectra via Kurie analysis, parametrization fitting, and
g_V/g_A extraction. Includes 32 new tests (18 fitter + 14 CW extractor).
Bump version to 0.3.0.
The resummation was previously applied to all energy points when the
flag was set, causing resummed and standard modes to differ everywhere.
Per spec, it should only replace C(beta)*ln(W0-W) with the resummed
power-law form when (W0-W) < delta_cut (~1e-3).
Adds delta_cut parameter (default 1e-3) and corrects the resummation
switch test to verify identical results far from endpoint.
- Add Z (nuclear charge) and A (mass number) parameters to RadiativeCorrection
- Implement O(Z*alpha^2) finite nuclear size correction per Sirlin 1987:
- Energy-dependent part: ln(m_p) - (5/12)*ln(2W) + 43/18
- Nuclear-structure-dependent part: Delta_F(Z,A) from modified Gaussian model
- Add small-beta Taylor expansion for numerical stability at threshold (beta < 1e-6)
- Extract _safe_beta() and _safe_tanh_inv_beta_over_beta() helper methods
- Remove unused log_wright_bessel import
- Add 14 new tests: Z-dependence, numerical stability, A parameter coverage
- Update docs/06-radiative-corrections.md with new API usage examples
All 70 tests pass. 14 new tests in 3 new test classes.
Implemented all planned corrections:
- finite-size e/m L0 and U
- atomic screening and exchange
- radiative (electron only so far)
Added plotter and csv_export
