Multiform per-form failure statuses (formstatus records, noformmatch errorcode
classes + -formerrors) are now sound suffix-viability verdicts: 'incomplete'
(viable) iff every supplied word was validly consumed as a prefix of the form
and the failure is pure exhaustion at end-of-input; anything already supplied
contradicting the form reports 'invalid'. Mechanism: viability-probe mode on
private::get_dict_form suppressing only the position-guarded pure-exhaustion
raises (count min-shortfalls, missing-required checks, adhoc option value at
end) while final validation of the consumed words stands as the soundness
backstop; multiform candidacy and parse_status's single-form formstatus record
confirm each classify-'incomplete' failure with one probe re-parse. Rendered
noformmatch form lines marked '(viable - needs more arguments)'/'(not viable)'
after the stable "form '<fid>':" anchor. Consumer contract documented in the
parse ('Multiform failure contract') and parse_status argdocs. Documented
conservatism: input ending inside a multi-member type clause reports invalid.
New testsuite formviability.test (acceptance scenarios, option position
guards, single-form record soundness, clause conservatism, message marking);
forms.test verdict pins deliberately updated (ms/idle incomplete->invalid for
type-screen rejections). punkshell 0.41.3 (patch: refined multiform error
classification/reporting at the shell surface).
Goal G-152 activated (user-directed) and flipped achieved 2026-08-02 with
acceptance verified via runtests (args subtree green; full-suite parity with
stashed baseline); entry archived to GOALS-archive.md, detail file to
goals/archive/ with verification evidence; consumer pointers pushed to
G-044/G-150 notes.
