Create pyphi/conf.pyi to provide proper type annotations for the Config class's Option descriptor pattern. Type checkers cannot see through descriptors to the actual value types, so this stub file declares the actual types (int, bool, str, Mapping) for all 35 config options. This is the standard Python approach for typing descriptor patterns and enables type checking without any runtime changes. Fixes ~28 pyright errors across multiple files (compute/parallel.py, cache/__init__.py, cache/cache_utils.py, and others). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <[email protected]>

PyPhi computations involve elements with vastly different costs (e.g.,
mechanism sizes range from 1 to 2^n-1). Uniform chunking causes load
imbalance. Adaptive chunking groups elements by estimated work.
- pyphi/parallel/chunking.py: Work estimation and balanced chunking
- estimate_work_size(): Context-aware cost estimation for mechanisms,
partitions, purviews, cuts
- adaptive_chunk(): Creates equal-work chunks instead of equal-size
- calculate_target_work(): Optimal chunk sizing for worker count
- test/test_chunking.py: Comprehensive tests for chunking logic
Also removes Ray from optional dependencies since local backend uses
stdlib ProcessPoolExecutor.

Replace Ray-based parallel execution with pluggable backend system:
- Unified MapReduce class with backend parameter ("auto", "local")
- Local backend uses ProcessPoolExecutor (~1-5ms vs Ray's 100-500ms)
- Preserve existing API: parallel, ordered, shortcircuit, progress
- Tree-structured execution via existing TreeConstraints system
- Cancel remaining futures on short-circuit
Backend selection:
- "auto": Auto-detect best available (currently always local)
- "local": ProcessPoolExecutor for single-machine parallelization
Co-Authored-By: Claude Opus 4.5 <[email protected]>
- Remove Ray imports and RAY_CONFIG option from conf.py - Add PARALLEL_BACKEND config option (currently only "local") - Add deprecated options handling for old RAY_CONFIG in config files - Delete pyphi/deferred/ray.py (Ray lazy loading) - Delete old pyphi/parallel/progress.py (replaced by backends/progress.py) Co-Authored-By: Claude Opus 4.5 <[email protected]>
- Remove Ray fixtures from conftest.py - Update test_parallel.py for ProcessPoolExecutor backend - Use module-level functions instead of lambdas (pickling requirement) - Update uv.lock with dependency changes Co-Authored-By: Claude Opus 4.5 <[email protected]>
DistanceResult now has a short __str__ representation that uses fmt_number(), making it display concisely when nested inside formatted PyPhi objects. The verbose __repr__ is preserved for standalone REPL inspection. Co-Authored-By: Claude Opus 4.5 <[email protected]>

The previous JSON version check required exact version matches, which caused issues when loading data saved with different dev builds (e.g., 1.2.1.dev1534+g12345 vs 1.2.1.dev1600+gabcde from hatch-vcs). This change: - Adds VALIDATE_JSON_VERSION config option to disable version checking - Allows compatible versions with matching base but different dev suffixes - Improves error message to say "incompatible" instead of "different" Co-Authored-By: Claude Opus 4.5 <[email protected]>
Add comprehensive test coverage for two previously untested modules: test/test_tree.py (43 tests): - TreeSpec dataclass (creation, immutability, equality) - TreeConstraints base class (construction, validation, parameter enforcement) - TreeConstraintsSize (branching by total elements, simulate, get_initial_chunksize) - TreeConstraintsChunksize (branching by chunksize, zero-safety, simulate override) - get_constraints() factory (class selection, error cases, parameter passthrough) test/test_progress.py (20 tests): - LocalProgressBar basic functionality (construction, queue property, auto-start) - Context manager protocol (enter/exit, cleanup, double-close safety) - Progress updates (queue operations, post-close behavior) - Threading behavior (background thread, daemon status, cleanup) Addresses TODO at test/test_parallel.py:372 for tree.py tests. Co-Authored-By: Claude Opus 4.5 <[email protected]>
Expand test coverage for the chunking module: - Add test_complex_context: verify quadratic scaling (size^2) for the "complex" context in estimate_work_size() - Add TestChunkedByWork class with 6 tests for the high-level API: - Basic usage with default parameters - Empty iterable handling - Zero total work edge case - Custom size function support - Context parameter passthrough - Generator materialization Co-Authored-By: Claude Opus 4.5 <[email protected]>
- Add TestGetNumProcesses class with 5 tests for edge cases: - Zero cores raises error - Negative cores calculation (e.g., -1 = all CPUs) - Too-negative cores raises error - Cores exceeding available returns available count - Positive cores returns configured value - Fix test_map_with_shortcircuit: remove unused _parallel parameter and align assertion logic with actual kwargs["ordered"] value. The test was incorrectly using an unrelated random boolean for assertion mode instead of the actual ordered parameter passed to MapReduce. - Replace TODO comment with note pointing to test/test_tree.py Co-Authored-By: Claude Opus 4.5 <[email protected]>
Replace ProcessPoolExecutor with loky's reusable executor to enable cloudpickle serialization. This allows functions defined in __main__ (e.g., Jupyter notebooks) to be sent to worker processes.

Test JSON fixtures were created with version 2.0.0a1 (local tag), but CI derives a different version since this tag isn't on the remote. This disables VALIDATE_JSON_VERSION in conftest.py so tests can load fixtures regardless of version mismatch. Co-Authored-By: Claude Opus 4.5 <[email protected]>
- Configure Towncrier in pyproject.toml with 8 fragment types matching existing CHANGELOG categories (feature, change, config, optimization, fix, doc, refactor, misc) - Add towncrier-check pre-commit hook to validate changelog fragments - Create changelog.d/ directory with README and migrated fragments - Migrate existing unreleased CHANGELOG entries to fragment files - Update AGENTS.md (CLAUDE.md symlink target) with changelog fragment instructions in development workflows Co-Authored-By: Claude Opus 4.5 <[email protected]>
Replace thread-safe queue-based progress tracking with simple tqdm wrapper. The previous implementation used multiprocessing.Manager queues and background threads for per-item updates from workers, which broke tqdm's notebook widget rendering. Changes: - Remove queue/thread complexity from LocalProgressBar - Update progress per-chunk in main thread instead of per-item - Add miniters=1 and mininterval=0 for immediate display updates - Add refresh() call to force widget updates in notebooks - Update tests to match simplified implementation The per-chunk update model is simpler, works with notebook widgets, and has negligible overhead since updates are already infrequent.

Fix get_constraints() to use TreeConstraintsChunksize when chunksize is explicitly provided, even when total is known. Previously, an explicit chunksize=10 would be ignored when total was available, defaulting to TreeConstraintsSize which calculates chunksize as total/branch_factor. This caused fewer chunks than expected (e.g., 2 chunks of 30 instead of 6 chunks of 10), making progress bar updates appear as single jumps rather than incremental updates.

The old name was technically imprecise - we control worker processes, not CPU cores. The new name: - Accurately describes what's being configured (worker processes) - Is consistent with PARALLEL config option naming - Follows common conventions (num_workers, max_workers) Updated all references in code, tests, config files, and error messages to use "workers" terminology instead of "cores".
