Module commands 

The command registry: every control word and environment the tier-1 surface knows, each with its parse behavior, plus the known tier-2 vocabulary so unsupported constructs fail as precise, named, tier-tagged errors (the coverage ratchet’s unit — G0-4’s normative counting rules).

The tier-1 surface is the §11.4 seed vocabulary united with the G0-4 rank extension (construct_table.tsv in franken_manim); the two T1-by-rank preamble commands the Reference’s default template defines — \minus and \mathds — are built in here as the seed of the default preamble pack (generalized macro packs land with their own bead).

Enums

ConstructStatus

Parse-level support status of a construct, queryable in the construct table’s own naming scheme (\frac, env:array, script:sup, char:U+00F6, …). This is what the coverage ratchet and the corpus goldens consume.

Tier

Construct tiers, per the G0-4 harvest.

Constants

LAYOUT_PENDING_TRACKING

Where parse-supported constructs whose layout has not landed yet are tracked (environments, drawn/stretchy constructions, macro packs).

TIER2_TRACKING

Where unsupported-but-known constructs are tracked.

UNTIERED_TRACKING

Where unknown (untiered) constructs should be reported.

Functions

construct_status

Parse-level support status for a construct named in the G0-4 construct table’s scheme: \frac (control word), \\, – i.e. a backslash plus one non-letter char (control symbol), env:name, script:sup, script:sub, prime, tie, alignment-tab, math-island, or char:U+XXXX.
