Option naming across the surfaces

The 1.x API cannot rename options, so this page records the canonical name of each option and the aliases accepted on each surface. Removals are scheduled for 2.0 (Task 17.1). The deprecation mechanism is documented in docs/guide/deprecation.md.

Concept	Rust	CLI	Python	WASM	Alias / note
Symmetry tolerance (Angstrom)	SymmetryOptions::symprec	--symprec	symprec=	symprec	tolerance is the spelling in the docs; symprec is kept
Angle tolerance (degrees)	SymmetryOptions::angle_tolerance (radians in Rust)	--angle-tolerance (degrees)	angle_tolerance= (radians, Python convention)	angle_tolerance	CLI converts degrees at the boundary
Matcher length tolerance	MatcherOptions::ltol	--ltol	ltol=	ltol in options JSON	relative length
Matcher site tolerance	MatcherOptions::stol	--stol	stol=	stol	Angstrom
Matcher angle tolerance	MatcherOptions::angle_tol	--angle-tol	angle_tol=	angle_tol	degrees
Grid spacing	PoreOptions::spacing	--spacing	spacing=	spacing	Angstrom
Probe radius	PoreOptions::probe_radius	--probe	probe=	probe	Angstrom
Number of workers	ParallelOptions::threads	--threads	set_threads(n)	n/a (browser threads)	process-wide in Python
Format hint	reader hint argument	extension or - stdin	format_hint=	hint	content sniffing when empty
Random seed	seed	--seed	seed=	seed in options JSON	required for determinism
Temperature (K)	WidomOptions::temperature	--temperature	temperature=	temperature	adsorption only
Pressure (bar)	GcmcOptions::pressures	--pressures	pressures=	pressures	adsorption only

Deprecated aliases

No alias is removed in 1.x. The following aliases are candidates for removal in 2.0 and are accepted now:

• Python: interpolate_structures (preferred: interpolate).
• Python: mof_read_database and mof_screen (the Rust names are read_core_mof and screen_database; the Python mof_ prefix is kept).
• WASM: every *_info name (the object-returning form is preferred for new code; the old names remain).
• CLI: --angle-tol and --angle-tolerance are synonyms in the matcher.

Rules for new options

1. One concept, one canonical name per surface; the table above is the source of truth.
2. A new surface keeps the Rust name unless it conflicts with the host language convention (for example, Python exposes radians while the CLI and Rust boundary use radians internally and degrees at the CLI flag).
3. Any alias must be additive, documented here, and must warn once through the deprecation mechanism.
