a phase imidate handler — Tier-D iminoester functional-class naming.

orthonym.assembly.handlers.imidate.name_imidate(features, mol=None, style='pin')#

a phase Tier-D iminoester functional-class handler.

Emits “alkyl alkanimidate” PIN per IUPAC. Style parameter is ignored per internal notes (single PIN per compound).

Algorithm (per AUDIT): 1. Get iminoester atom-match: (C_carbonyl, =NH, O, C_alkyl) tuple. 2. Identify the alkyl word (R’): atoms reachable from C_alkyl

excluding the C_carbonyl -> O path. Generate substituent name via carbon-count lookup.

  1. Identify the chain stem (R): atoms reachable from C_carbonyl excluding =NH and =O paths. Generate chain stem with -imidate suffix.

  2. Emit two-word name: “{alkyl} {stem}imidate”.

Returns None if either branch fails (gate-fail per -04 contract; dispatch_inner cascades to next entry).
