7.4.Name resolution (Since 1.1.0)

A gloss token's name (after removing a trailing ! and any (args)) resolves against the lexicon, case-insensitively:

1. Exact match. If exactly one entry has that name, it is used. A draft entry resolves when it is the only match. If more than one entry has that name (a concrete entry and a draft included), the script is in error (ambiguous gloss name).
2. Explicit variation NAME#var. If no entry is named NAME#var exactly, the token falls back to the entry named NAME (the same exact-match rule applies), never to a sibling variation. If neither exists, the name is unknown.
3. Bare variation family. A name without # that matches no entry exactly, but heads entries named NAME#…, picks one member uniformly at random, choosing among concrete (non-draft) members when any exist, otherwise among all members. The pick is re-rolled on every compose, and a producer serializing the script MUST keep the bare NAME.
4. Otherwise the name is unknown (unknown gloss), which is an error.

Expression names (@name) resolve the same way, without variations: one match is used; none is unknown expression; more than one is ambiguous expression name.

Aliases and composed glosses are lexicon-level entries, defined here only for resolution:

• An alias name resolves to its main gloss (one hop) and uses that gloss's keyframes. A source dependency is recorded against the main gloss.
• A composed gloss stores a script and the keyframes composed from it. In a sequence it is placed like any gloss. The script of a composed gloss MUST NOT reference another composed gloss (no chains, so no cycles) and MUST NOT use a bare variation family (it must be stable); each is an error. When a composed gloss is composed, its keys are re-based so the first keyframe is frame 0 (no lead-in or tail-out), expression markers are baked into the pose keyframes of the affect groups h b f m as instead of being kept as references, and NAME! fills from the registry defaults. A script that places nothing is an error.
