Peritheos 0.18.0

Installation change: pip install peritheos installs EOS calculations,
structures and parameters. Use pip install "peritheos[datasets]" to add the
matching optional observation package. Existing installations that use bundled
observation values should install the extra when upgrading.

Added

• Add typed supporting-study dataset access through list_studies(),
  get_study_document() and get_study_dataset(). Admit the two unchanged
  Barker (1987) numerical resources after a source-specific redistribution
  assessment: seven liquid comparison rows and 32 selected figure readouts.
  Preserve theory/experiment roles, unspecified solid phase, graphical bounds,
  source copyright and not_reproduced status. No executable Barker EOS is added.
  Core installs retain public context; the version-matched optional package
  supplies values, scoped notices and exact review/resource bindings.

Changed

• Replace all ten inherited peak lists (452 rows) with 1,154 independently
  calculated X-ray reference lines. Preserve originals privately, all EOS and
  observation evidence, and explicit proxy/occupancy limits. Add six CC0 COD
  CIF inputs and an independent ideal model; three published numerical-parameter
  models retain source-license caveats. Correct the SnO2 structure citation,
  update the Fe3S proxy from COD, and ship reproducible inputs and scoped notices.
  The seven Holland/THERMOCALC collection cases remain unresolved.

• Replace the two ICSD-linked post-perovskite structural inputs with freshly
  acquired CC0 COD 9009217. Preserve original records privately and all existing
  cell/site numbers, EOS parameters, observations and scientific dispositions.
  Clarify ab initio coordinates using the observed high-pressure cell and the
  Fe-bearing material's pure-MgSiO3 topology proxy. Ship the unchanged COD CIF,
  update source bindings and notices, and reduce unresolved runtime compilation
  cases from 19 to 17 without extending the data grant to publications or EOSs.

• Review all 685 EOS and 234 structural/diffraction components without changing
  scientific files. Add source/runtime bindings, component/source-group indexes
  and installed compilation notices; preserve the pinned Dioptas upstream MIT
  attribution in both packages. Keep source grants separate from numerical-content
  assessments and explicitly identify the remaining 17 collection/acquisition
  components still present in the runtime export. Observation selection and
  historical release rights statements remain unchanged.

• Split experimental observation values from the default Python distribution.
  peritheos retains structures, EOS parameters, uncertainties, calibration and
  source/validation summaries; peritheos[datasets] adds the version-matched
  peritheos-datasets package. Select 451 material dataset entries after the
  numerical redistribution review: preserve the 44 earlier source declarations,
  add 363 scoped factual-content assessments, one verified Zenodo CC BY 4.0
  extraction and three author datasets with separately assessed literature inputs.
  Add four independently calculated Campbell polynomial entries, preserving the
  original integration tables as held evidence and their approximation mismatch.
  Trace all 21 selected Morard cold rows to Ohfuji (2007) and Ono/Kikegawa (2006)
  without changing original values, errors or source declarations.
  Admit ten views of the shared Shen/Smith experimental numerical collection and
  the fixed AIP copper/Anderson gold excerpts after individual collection-rights
  assessments, retaining original source terms and scientific qualifications.
  Admit 21 Sakai/Ismailova/iridium numerical extractions after source-specific
  applicability assessments; retain all original NC/ND notices and the Sakai
  S8 literature-index hold. Add an independently generated 37-edge primary-source
  lineage graph and two views of a new 1717-row NNO relative pressure integral;
  preserve their partial scope, unresolved 0.0143-log-unit source difference,
  missing absolute Gibbs inputs and original scientific dispositions. These
  additions bring the catalog to 456 entries. Hold five entries in total, including the four
  original Campbell integration views. Record the existing Sakai S9 first-pressure
  normalization without changing source values. Retain general redistribution
  caveats and exact installed review/manifest bindings. Preserve complete
  repository evidence and original numerical values; build separate, standalone
  source archives without mutating the checkout.
  Missing optional data report installation/source guidance. No runtime network
  access or automatic download is introduced. This changes default observation
  availability; the two distributions are released together at the same version.

Fixed

• Replace the He thesis brucite structural reference with the explicitly CC0
  Zigan/Rothbauer COD 1000054 CIF. Preserve original evidence privately and
  exclude the superseded CIF and copied coordinates/refinement from future
  distributions. Retain all EOS coefficients, observations and dispositions;
  update structural provenance, license notices and inventory.

• Remove the four Fei publisher/source raster figures from the source tree and
  future distributions. Replace three plots that embedded them with numerical
  readout/calculation plots. Preserve original hashes, calibrated pixel readouts,
  scientific findings and private evidence; numerical replay no longer requires
  the source rasters and does not claim a fresh source-image verification.
  Update the licensing inventory without rewriting published release evidence.

• Exclude the original Tateno KCl XLSX and redundant Chidester ThO2 supplement
  ZIP from the source tree and both distribution formats. Preserve originals
  privately and retain unchanged numerical CSVs, source hashes and manifests.
  Keep numerical KCl replay available; make fresh workbook inspection an
  explicit checksum-verified operation with a separately supplied original.

• Verify the current COD CC0 source declaration against the bundled vanadium
  and superhydrous-phase-B CIF payloads. Add an installed, scoped CIF notice
  and source/hash review receipt; retain all CIF bytes and legacy headers.
  Keep He (2023) thesis-derived brucite source terms explicitly unresolved,
  including the limitations of failed live repository requests.

• Ship full Rust dependency licenses, COPYRIGHT/NOTICE files, additional
  source-header attributions and the audited standard-library copyright
  document in both distribution formats and license metadata. Verify source
  archives against Cargo.lock, map all five target graphs, pin the official
  wheel compiler and reject stale notices or unexpected bundled native code.
  Document custom-toolchain rebuilding and provide an unsigned Morard
  author-data permission template without changing existing grants.
