v0.7.0 — CNRS-native scientific state

Added a consolidated CnrsScientificState object for science workflows. The state object keeps CNRS-H local jets as the primary representation and carries source expressions, scale units, branch/path metadata, local-domain metadata, claim-status labels, and observation maps.

Added:

• cnrs/cnrs_scientific_state.py
• cnrs/science/state.py
• tests/test_cnrs_scientific_state.py
• examples/science_workflows/cnrs_scientific_state_demo.py
• docs/CNRS_SCIENTIFIC_STATE.md

This release marks the start of the v0.7 line: native scientific objects built on top of the CNRS-H calculus spine.

Release Notes

v0.7.0 — CNRS-H Branch-Aware Local Continuation

v0.7.0 adds a conservative branch-aware continuation rebuild layer. In v0.6.2, continuation paths updated branch-state metadata on CnrsHJet. In v0.7.0, continued_jet_from_symbolic(...) can shift explicit symbolic branches in supported log, sqrt, and pow_branch expressions from path/winding events, then rebuild the finite CNRS-H jet from the continued expression.

Added:

• cnrs/cnrs_h_continuation.py
• cnrs/h/continuation.py
• tests/test_cnrs_h_continuation.py
• examples/science_workflows/cnrs_h_branch_continuation_demo.py
• docs/CNRS_H_BRANCH_CONTINUATION.md

Claim status: local finite-order coefficient recalculation for supported symbolic expressions; not full global analytic continuation or Riemann-surface lifting.

v0.6.2 — CNRS-H Path and Winding Tracking

v0.6.2 adds conservative path/winding scaffolding to the CNRS-H branch-aware layer. It introduces piecewise-linear continuation paths, winding-number diagnostics around isolated branch points, branch-state updates for log/sqrt/power metadata, and CnrsHJet.continue_along(...) for recording path-induced branch changes.

Added

• cnrs/cnrs_h_path.py
• cnrs/h/path.py
• tests/test_cnrs_h_path.py
• examples/science_workflows/cnrs_h_path_winding_demo.py
• docs/CNRS_H_PATH_CONTINUATION.md

Status

This release does not claim full analytic continuation. It supplies local path/winding bookkeeping for finite CNRS-H jets and prepares the toolkit for later coefficient re-expansion and Riemann-surface work.

v0.6.2 — CNRS-H Branch-State Propagation

v0.6.2 moves branch-state bookkeeping into the CNRS-H local jet layer. Branch choices from symbolic log, sqrt, and pow_branch expressions now become metadata on finite CNRS-H coefficient jets, and that metadata is preserved through the native local operations.

Added:

• cnrs.cnrs_h_branch — branch-state merge and extraction helpers.
• tests/test_cnrs_h_branch.py — branch extraction, propagation, composition, and chain-rule metadata tests.
• examples/science_workflows/cnrs_h_branch_state_demo.py.
• docs/CNRS_H_BRANCH_STATE.md.

Updated:

• CnrsHJet now carries branch_state and branch_note.
• jet_from_symbolic(...) extracts local branch state from symbolic expressions.
• Jet differentiation, integration, center shifting, multiplication, composition, and finite chain-rule verification preserve or conservatively merge branch metadata.
• cnrs.h and flat imports expose the branch helpers.

Scope: local branch-state bookkeeping inside finite CNRS-H jets. This is not yet path-dependent analytic continuation, Riemann-surface lifting, or monodromy tracking.
