Changes in version 0.4.2                        

Documentation

  - A vignette carries one task end to end on synthetic or bundled data,
    offline, and is built and run by R CMD check.
  - Runnable @examples added or corrected across 20 help pages. Each
    runs offline in seconds, writes nothing outside tempdir(), and is
    executed by R CMD check; anything needing a device, a download or an
    optional backend is fenced with the reason stated.
  - The README's quick start runs as written: it attaches the package,
    builds its own inputs, and uses only hard dependencies.

                        Changes in version 0.4.1                        

  - De-identification and data-subject handling accept the canonical
    MultiPhysioExperiment. They previously tested for
    MultiRatePhysioExperiment only, which would have rejected a
    container built by the current constructor.

                        Changes in version 0.4.0                        

  - deidentify() now handles PhysioCohort (the multi-subject container):
    it de-identifies each subject timeline and the subject-level colData
    (where cohort PII concentrates), and stores the merged report in the
    cohort metadata slot. The structural subject_id linkage key is
    replaced with a stable positional pseudonym so the container stays
    valid and internally consistent while the real identifier is
    removed. Previously deidentify() aborted on a PhysioCohort.

                        Changes in version 0.3.0                        

  - Add deterministic lifecycle and risk-management template rendering
    with bundled source-edition metadata and verified template
    inventories.
  - Add project-owned risk matrices and normalized
    requirement-risk-control-test traceability with objective-evidence
    hashing.
  - Add read-only ecosystem engineering-readiness checks and
    deterministic JSON, CSV, and Markdown reports.

                        Changes in version 0.2.0                        

  - Add conservative Safe Harbor candidate policies and structured
    de-identification auditing.
  - Add keyed pseudonymization, authenticated encrypted
    re-identification maps, and deterministic within-subject date
    shifting.
  - Add structured header scrubbing and plan-first data-subject workflow
    helpers.

                        Changes in version 0.1.0                        

  - Add deterministic SHA-256 audit chains over complete
    PhysioExperiment records.
  - Add externally authenticated electronic signatures bound to record
    state and audit-chain heads.
  - Add structured verification reports for audit and signature
    failures.
