                        Changes in version 0.4.0                        

  - Add sci_report(), an end-to-end readiness report that composes the
    SCI, the decision band and its critical gate, the per-pillar
    breakdown, the findings most worth acting on, and the pillars that
    offer the biggest improvement into one object with a readable print
    method. Pass targets for a distance-to-goal section, or a profile
    configuration as config for an authority-calibrated report. This is
    the single call that answers "where do we stand and what do we fix
    next" from an evidence table.

                        Changes in version 0.3.0                        

  - Add sci_targets() and sci_gap_to_target(). The first records the
    readiness goal a submission is aiming for, either a band name such
    as "ready" or a numeric SCI, with optional per-pillar minimums. The
    second measures how far a scored run is from that goal and, for each
    pillar, reports the SCI points that closing it would add, ordered so
    the biggest lever comes first. Where sci_diff() answers "are we
    moving in the right direction", this answers "how far are we from
    filing, and what should we fix next".

                        Changes in version 0.2.1                        

  - Add sci_snapshot(), sci_diff(), and sci_snapshot_history() for
    tracking readiness over time. A snapshot records the SCI, band, and
    pillar and indicator scores for one run under a label; sci_diff()
    reports what moved between two runs (overall SCI change, band
    change, per-pillar deltas, and which indicators improved, regressed,
    were added, or removed); and sci_snapshot_history() binds a series
    into a tidy table for a trend plot. This turns the SCI from a
    single-run report card into a way to answer whether a submission is
    on trajectory to file.

                        Changes in version 0.2.0                        

  - Add a non-compensatory gate to the SCI. An open critical finding
    (severity critical, result fail) now caps the reported band at
    conditional by default, so a strong score in one pillar cannot wash
    out a critical failure in another. The numeric SCI is left
    unchanged; only the band is capped, and compute_sci() records
    n_critical, gated, and a gate_reason. The gate is configurable
    through sci_config_default(gate = ...) and applies automatically
    through the standard pipeline. The default is a starting point
    sponsors should calibrate, not validated truth.
  - Add indicator_contributions(), which breaks a pillar score down into
    per-indicator contributions, ranks indicators by how many SCI points
    a fix could recover, and attaches a short remediation hint to each
    one.
  - Add sci_what_if(), which recomputes the pillar score and the SCI
    exactly as if one indicator had a different score, for planning
    remediation.
  - Add sci_confidence_interval(), a bootstrap confidence interval for
    the SCI so a readiness decision can account for measurement noise,
    with a format_sci_ci() helper for the compact SCI = 82.0
    [76.0, 88.0] form and a print method that flags when the interval
    straddles two decision bands.
  - Document confidence-interval interpretation in the scoring vignette.
  - Add vignette: "Case study: scoring a CDISC pilot for submission
    readiness", a worked walkthrough of the SCI on the example pharma
    evidence from r4subdata.
  - Add validation helpers: sci_degradation_curve() records how the SCI
    responds as passing checks are turned into failures,
    sci_monotone_check() confirms a curve never rises, and
    conformance_findings() produces an independent severity-weighted
    finding count for concurrent-validity checks.
  - Add vignette: "Validating the Submission Confidence Index", covering
    construct, discriminant, concurrent, and robustness validity, and
    documenting a calibration finding about how severity discounts
    passing credit.
  - Clarified the package DESCRIPTION: "R4SUB" expands to "Ready for
    Submission" (previously "R for Regulatory Submission", inconsistent
    with the rest of the ecosystem).

                        Changes in version 0.1.1                        

  - Add vignette: "Submission Confidence Index (SCI) Scoring" covering
    compute_pillar_scores(), compute_sci(), sci_explain(),
    sci_sensitivity_analysis(), and custom weight configuration.

                 Changes in version 0.1.0 (2026-03-03)                  

  - Initial CRAN release.
