punk::args::parse/get_dict with the default -form * (or any multi-form
selection) now attempts every permitted form instead of effectively
parsing form 0 only. Exactly one clean match auto-selects (result gains
a 'form' key; 'formstatus' reports every candidate when candidacy ran).
No match raises a 'noformmatch' validation error naming each candidate
form's first-line failure, ranked best-candidate first (leading-literal
affinity with the supplied words, then incomplete before invalid, then
declaration order). Several clean matches raise 'multipleformmatches'
naming the forms - deliberately no silent preference (recorded in the
goal detail); callers pass -form to disambiguate.
-form now accepts the documented list of form names/indices across
get_dict, parse, parse_status and arg_error via a shared resolver
(private::form_selection). arg_error renders the argument table for the
first listed form and marks all listed forms' synopsis entries; parse's
error render passes the ranked candidate list so the closest form's
argument table shows under the no-match message.
parse_status: 'form' is now the matched (or best-candidate) form - the
per-argument statuses and badarg marking are built for it - and the new
documented 'formstatus' key carries per-form status/failureclass/badarg/
message (caller-attributed), the per-form compatibility surface the
G-044 completion/hinting consumer needs on partial argument lists.
Engine restructure: the single-form parse body of get_dict extracted
verbatim to private::get_dict_form (argspecs resolved in the caller's
context before selection; no caller-frame use inside - verified).
Single-form definitions take the direct path unchanged.
Tests: forms.test GAP pins flipped (forms_parse_autoselect,
forms_parse_formlist_restriction) plus new coverage: shared-prologue
arity discrimination, noformmatch ranking + errorcode payload,
multipleformmatches + explicit -form disambiguation, formstatus in
results and parse_status. punk::args 198 pass / 1 pre-existing skip,
punk::ns 53/53, punk::lib 35/35.

## [0.12.14] - 2026-07-13
- punk::args 0.10.0 (G-041 increment): multi-form argument definitions now parse by automated form selection - punk::args::parse without -form attempts every form and auto-selects the one that cleanly matches ('lseq'-style multiform commands no longer fail with the first form's error when the arguments fit a later form). No matching form raises an error naming each candidate form's failure (best candidate first); arguments matching several forms raise an error naming them, with -form (which now accepts the documented list of form names/indices) restricting to the intended form. Parse results and parse_status report the selected form and every candidate's status ('form'/'formstatus' keys).
## [0.12.13] - 2026-07-13
- G-051 achieved: punk::ns 0.4.0 - the help system's doc walk now accepts the same choice-word abbreviations parsing accepts: 'i string is tr' resolves to the 'string is true' documentation exactly as 'string is tr 1' executes (unique prefixes, aliases, nocase; ambiguous/denied/unknown words stay at the parent exactly when parse rejects them). cmdinfo also reports the truthful cmdtype 'doconly' (was 'notfound') for documentation-only levels such as 'string is <class>' and documented TclOO method docids. punk::lib 0.4.1 adapts its script analysis to the new value with identical behaviour.

#0.10.0 - G-041 multi-form candidacy: punk::args::parse/get_dict with the default -form * (or any multi-form selection) now attempts every permitted form instead of effectively parsing form 0 only - a clean match against exactly one form is auto-selected, no match raises a 'noformmatch' PUNKARGS VALIDATION error naming each candidate form's first-line failure (candidates ranked best-first: leading-literal affinity with the supplied words, then incomplete before invalid, then declaration order - private::form_selection/form_literal_affinity/rank_form_failures), and several clean matches raise 'multipleformmatches' naming the forms (no silent preference - deliberate, callers pass -form to disambiguate). -form now accepts a list of form names/indices as documented (get_dict, parse, parse_status, arg_error; supplied order preserved - arg_error renders the argument table for the first listed form and marks all listed forms' synopsis entries; parse's error render passes the ranked candidates). Parse results gain a 'form' key (the parsed form; keys appended after 'id' - positional consumers unaffected) and, when candidacy ran, a 'formstatus' key reporting every attempted form's outcome; parse_status 'form' is now the matched/best-candidate form (per-argument statuses and badarg marking built for it) and gains the documented 'formstatus' key (per-form status/failureclass/badarg/message with caller attribution) - the per-form compatibility surface the G-044 completion/hinting consumer needs. Engine body extracted verbatim to private::get_dict_form (single-form parse; argspecs resolved before selection - no caller-frame use). forms.test GAP pins flipped (auto-selection, -form list restriction) + new coverage (shared-prologue arity discrimination, noformmatch ranking/errorcode, multipleformmatches, formstatus in results and parse_status).
#0.9.0 - G-071: allocation choice screen - get_dict_can_assign_value no longer blanket-accepts any word for an argument with a RESTRICTED choice set; where allocation has an alternative (the argument is -optional, or a further occurrence of a -multiple argument) the candidate word is screened with choiceword_match (the shared G-040 implementation: exact/alias/prefix/nocase semantics; -choicemultiple words screened per list member within min/max), and a non-matching word yields onward to later elements/clauses instead of being consumed and failing validation. Fixes the lseq-class in-form failures: an optional choice noise word between required values plus a trailing optional-member clause ('lseq 0 10 2', '0 10 by 2', '1 5 by 0' now parse; noise-word variants and prefix normalization unchanged; genuinely invalid arglists now get the plain excess-values rejection instead of blaming the unrelated optional). REQUIRED arguments are deliberately not screened - the word must fill them and validation's choiceviolation reporting stays informative. -choicerestricted 0 behaviour unchanged. allocation.test GAPs flipped; parse_status -form documented-order behaviour pinned (a prior mis-premise: -form was already supported before the withid/withdef tail per its synopsis).
#0.8.3 - G-071: silenced four more unconditional debug puts on get_dict's allocation retreat paths ("get_dict cannot assign val:... (111)/(222)/(333)/(444)") - these fired on stderr during NORMAL successful parses whenever an optional element's candidate word was rejected and allocation retreated (e.g. every noise-word skip when parsing if/lseq-modelled commands), polluting interactive output. Same class as the 0.2.3/0.8.2 finds. The retreat logic they marked is the target of the G-071 allocator-correctness work; behaviour unchanged, output only. New allocation.test characterization suite (reduced lseq-range/if-shape fixtures): current mis-allocation and misblame pinned as GAP tests (flip with G-071), noise-word variants and if-shape guards pinned as regression guards, parse_status -form absence pinned as GAP.
#0.8.2 - fixed stray debug output: an unconditional 'puts' in private::get_dict_can_assign_value ("checking tp '<type>' against value '<value>'") fired on multi-element clause type checks (e.g. parsing 'try ... trap ... on ...' style arglists against the tclcore moduledoc), polluting interactive output - now commented like its 0.2.3 companion. Found during G-041 prework probing (real-vs-model divergence sweep of if/switch/try/lseq).
