A word rejected by an OPTIONAL argument's allocation screen (G-071
restricted-choice screen, or the basic int/double/bool/number/dict type
screen) that subsequently overflows the argument list now reports the
specific rejection instead of "Received more values than can be assigned":
- choiceviolation naming the word and allowed choices, with -badarg/-badval
and the final-validation message template (Leading/Trailing argument
attribution), for choice-screen rejections
- typemismatch naming the declared (normalized) type, with -badarg/-badval,
for basic-type screen rejections
Mechanism: private::get_dict_can_assign_value returns a 'rejection' record
(single-member clauses only; literal-category mismatches deliberately not
recorded); get_dict_form collects first-rejection-per-word from the three
allocation call sites (leader/value split trial, leaders loop, values loop)
into a per-form store; the two toomanyarguments raise sites prefer a
recorded rejection for the unassignable word. Genuinely-surplus words still
report toomanyarguments; words consumed by later slots parse unchanged;
multiform selection (rank_form_failures) untouched.
errorselection.test _GAP pins flipped to the pointed expectations (pre-fix
behaviour pinned in the previous commit). punk::args buildversion
0.12.0 -> 0.12.1.
Closeout: G-082 flipped achieved + archived (index -> GOALS-archive.md,
detail -> goals/archive/ with mechanism/verification/residue recorded);
G-073 note updated to point at the new rejection-record seam;
src/modules/AGENTS.md authoring-ergonomics bullet re-documented (-optional 0
workaround no longer needed on >= 0.12.1; make.tcl keeps it - it runs
against the bootsupport 0.12.0 snapshot). Project version 0.12.28 +
CHANGELOG.
Verified: full punk/args suite 228/224/0-failed (4 intended skips) and
punk/ns 57/57 under Tcl 9.0.3; errorselection.test 7/7 under Tcl 8.7;
make.tcl frobnicate still pointed; goals_lint clean.
