The stringstartswith(*) arm of get_dict_can_assign_value''s multi-member
tail-clause reservation walk compared the prefix against $tp (the type
string) instead of $rv (the candidate value). Consequences (pinned pre-fix
in the previous commit):
- a later optional clause mixing literal(...) and stringstartswith(...)
members never had genuinely matching trailing words reserved - a greedy
-multiple argument swallowed them and the tail clause was silently lost
- a prefix text that happened to prefix the literal type string (e.g str vs
stringstartswith(str)) wrongly reserved NON-matching words, raising a
spurious toomanyarguments overflow
One-token fix; allocation_tailclause_ssw_reservation_GAP flipped to the
correct expectations (matching words reserved; non-matching words left to
the -multiple argument with no error); literal-only and no-match guards
unchanged. Known remaining approximation (pre-existing, noted in the
buildversion changelog): the walk still requires a literal* member in the
tail clause''s typelist to run at all - a stringstartswith-only tail clause
is not reserved.

No behaviour change (full args suite 224/0-failed, ns 57/57, 8.7 spot check).
Removed (~1100 lines of commented-out code, recoverable via git history):
- old-signature private::check_clausecolumn ("old version")
- _check_clausecolumn2 "interim version" experiment (its collect-all-clause-
failures idea preserved as an in-place note for G-072-era rework)
- pre-parsekey opts ordering loop, pasted opts-logic reference copy in the
values loop, disabled XXXliteral* switch arm, misc debug remnants
MAINTENANCE comments: the leaders/values loop-parity notes expanded into a
dated refactor assessment - shared clause-assignment helper extraction is
indicated (drift is real: G-082 duplicated its selection block, parsekey
idents exist only values-side) but deferred to ride the G-084 parity work
under the G-046 hot-path constraints; mirror-or-justify rule stated at both
loops. The old "synchronize with values loop" todo folded into it.
Documentation accuracy:
- get_dict PUNKARGS + doctools: real result keys (leaders opts values
received solos multis id form, + formstatus when candidacy ran); directive
lists corrected beyond @cmd/@leaders/@opts/@values; false primordial claims
removed ("only supports -flag val pairs, not solo options" / "only the
last value is used")
- parse -help example fixed (dict exists bracketing was broken) and header
dofilestuff example fixed (stray trailing 1 after -type existingfile);
punk::parse -> punk::args::parse; typos
- goal cross-refs annotated at code sites (G-053 -multiple ranges, G-084
values/leaders parsekey incompleteness); wrong test-name comments corrected
to parsekey_repeat_ordering
Flagged, deliberately unfixed (comment only, no pins exist): suspected bug in
the multi-member clause "stringstartswith(*" arm of get_dict_can_assign_value
- it matches against $tp (the type string) instead of $rv (the value), so it
always succeeds.

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

New punk::args::formcheck <id> ?-return dict|summary?: reports the form pairs
of a multiform definition that some argument list could cleanly match
simultaneously (the multipleformmatches inputs). Static pairwise pass over the
resolved FORMS enumerates each form's positional word-slot chains (leaders then
values; -optional and ?-wrapped clause-member branching; -multiple capped;
options excluded - order-free), screens aligned equal-length chains per
position (discriminator words via choiceword_match, type witnesses from a
small table), and CONFIRMS every candidate witness arglist with a real
single-form parse against both forms (parse_status - no raise, no
user-supplied words, no define/resolve cost). Findings are therefore witnessed
- discriminated form pairs cannot false-alarm; misses (exotic types,
option-requiring forms, enumeration caps) are the documented conservative
direction. Classes: type_weakness (discriminator aligned with a permissive
non-validating type - any/none/string/ansistring/globstring/expr/script) vs
structural (forms genuinely share an argument shape).
New @form key -overlapallowed <formname-list> sanctions a KNOWN overlap on
either pair member: the finding reports with sanctioned 1 and leaves the
result's unsanctioned list (the actionable/gate subset). Parse behaviour is
never affected; unknown form names are rejected at definition resolve
(end-of-forms cycle). @form directive doc updated.
tclcore moduledoc 0.3.4: the documented after cancelid/cancelscript overlap
(runtime-liveness ambiguity, 0.3.0 record) sanctioned on the cancelid form -
::after now reports zero unsanctioned findings while 'after cancel <id-shaped>'
still raises multipleformmatches. ::lseq deliberately unsanctioned: formcheck
reports range/start_count (witness {1 count 1}) AND range/count (witness
{1 by 1}) - both real, both rooted in the expr-typed end slot, kept visible
pending an expr syntax-validating type (G-069/G-070).
Tests: new args/formcheck.test (7) - no-finding cases (parse withid/withdef
pair, afterish/sharedform fixtures), class+sanction fixture, unknown-form
rejection, -return summary, ::lseq/::after pins with witnesses re-verified,
sanction parse-neutrality. punk::args suite 210/210, punk::ns 57/57.
G-074 achieved and archived (acceptance review in the detail file); G-055
verification gate gains the formcheck step (unsanctioned must be empty for
regenerated multiform commands).

User-reported: 'i join' emitted the bad-@dynamic warning 4 times ('i
join test' 6). Root cause was a real inefficiency, not just noisy
logging: a @dynamic definition whose round-1 tstr output has no
round-2 parameters bypassed argdefcache_unresolved entirely, so every
resolve in the 'i' flow (doc walk, advisory parse, get_spec for the
render, synopsis) redid display masking plus the full round-1 tstr and
re-warned. Such definitions now cache as a zero-param unresolved entry
- consistent with the round-1 freezing legitimately dynamic
definitions already get - so later resolves take the cheap cached
branch and the warning emits once per definition per interp.
Warning wording corrected: @dynamic is not a complete no-op for a
parse-inert definition - deferred display fields still re-expand per
render instead of caching - so the message says removal is appropriate
only if that display behaviour is unintended. Sweep of all 462
registered ids: ::split, ::array, ::join carry the parse-inert tag
(left in place pending the display-refresh decision).
Incidental finds from the sweep: the malformed ::tcl_startOfNextWord
tclcore definition (double-quoted -help with unescaped quotes in the
embedded man-page example) failed to resolve at all - now braced per
the define quoting rules, 'i tcl_startOfNextWord' works; and resolve's
malformed-record error path printed dev diagnostics (full records dump
+ ::testrecord global) - commented per the stray-debug convention.
Tests: new args/dynamic.test (warn-once + cached parse, legit-dynamic
round-2 freshness; stderr captured via channel transform). punk::args
203/204 (1 pre-existing skip), punk::ns 57/57. Live-verified: 'i join'
and 'i join test' each emit the warning exactly once (punk902z src).

Documentation-only. The define -help gains two sections: 'Registration
styles' (direct define vs deferred lappend-PUNKARGS registration - the
lazy scan/on-demand definition mechanics, why moduledocs and the module
template use it, PUNKARGS_aliases, punk::args::status timings) and
'Interpolation (tstr placeholders) and the defspace' (display-field
deferral vs parse-field expansion vs @dynamic; the defspace rule with
the argdoc-child subtlety; the silent-literal fallback; safe patterns
for load-time-computed values). Motivated by the ::after id-shape
harvest misattribution - corrected record in goals/G-055.

cmdhelp ('i'): the -form option defaults to * (was 0) with parse's
list semantics, and both render sites present the form the advisory
parse selected - 'i after cancel <id>' presents the cancel form's
argument table with its synopsis line underlined; 'i lseq 0 10 2'
presents the range form info-scheme. When no form matches, the ranked
candidates are passed to arg_error (best candidate's table, all
candidates marked, message naming each form's failure); when several
forms match, all matching forms are marked under the ambiguity message.
punk::ns::synopsis ('s'): trailing argument words after a multiform
command path underline the form(s) they match - matching forms from the
advisory parse's formstatus, or the best candidate when none fully
matches ('s after cancel someid' marks both cancel forms; 's lseq
0 10 2' marks the range form). Ordinal line position maps lines to
declaration-order forms in both full and summary renders; marking is
skipped under alias-currying excess or an explicit -form.
punk::args 0.11.0: the documented @form -synopsis override now renders
in punk::args::synopsis full and summary output (arg_error honoured it
already) - the adjacent forms.test GAP flipped
(forms_form_synopsis_override_rendered). Candidate ranking extended:
form_literal_affinity treats required RESTRICTED-choice arguments as
discriminators via choiceword_match (the tclcore models express
subcommand words as -choices), so 'after cancel' ranks the cancel
forms first instead of falling back to declaration order.
Real-model findings recorded in the goal detail: 'after cancel someid'
is genuinely ambiguous in the doc-faithful model (cancelid vs
cancelscript - real Tcl disambiguates semantically); 'lseq 1 count 5'
ambiguity traces to the expr-typed operands (noted in G-055 as a
model-tightening candidate alongside TIP 746).
Tests: cmdhelp.test gains the multiform doc-surface pins (autoselected
form presented, noformmatch best-candidate table + candidate naming,
synopsis marking present/absent). punk::ns 57/57, punk::args 198/199

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.

Root cause: get_dict_can_assign_value blanket-satisfied the member check
for any argument carrying choices, so an optional restricted-choice value
(the lseq '..'/'to' noise word) consumed any word whenever arity
permitted, starving later elements/clauses and failing validation with a
confusing trailing-choices error ('lseq 0 10 2' shape).
Fix: an allocation choice screen using choiceword_match (the shared G-040
implementation - exact/alias/prefix/nocase semantics; -choicemultiple
words screened per list member within min/max), applied only where
allocation has an alternative: -optional arguments and further
occurrences of -multiple arguments. Required arguments are deliberately
not screened - the word must fill them and validation's choiceviolation
reporting stays informative (the existing parsestatus/cmdhelp/choices
pins forced and now document both refinements). -choicerestricted 0
behaviour unchanged.
Results: the allocation.test GAPs flipped ('1 2 3' and '1 2 by 3' parse
with correct clause shapes {{} 3}/{by 3}; '1 2 3 4' gets the plain
excess-values rejection instead of blaming the unrelated optional);
prefix normalization survives the screen; all noise-word variants and
if-shape guards unchanged. lseq moduledoc matrix parses per lseq.n under
-form range, and 'i lseq 0 10 2' works end-to-end. Remaining lseq
divergences trace to G-041 form selection or the -type expr laxity
recorded in G-055 - not allocation.
Also corrected an increment-1 mis-premise: parse_status ALREADY accepts
-form before the withid/withdef tail per its documented synopsis - the
probe had passed it trailing. GAP replaced by
parsestatus_form_option_order (correct-order acceptance incl. the form
key, trailing rejection). No code change was needed for that acceptance
clause.

G-071 flipped proposed -> active (user direction 2026-07-12).
New allocation.test (7 tests) with reduced fixtures isolating the failing
shape from the tclcore moduledoc: the lseq-range shape (start ?sep? end
?by-step clause?) reproduces the moduledoc failures exactly. Current
mis-allocation pinned as GAP tests ("1 2 3" -> invalid blaming sep,
"1 2 by 3" -> incomplete blaming end, "1 2 3 4" correctly invalid but
misblaming sep), noise-word variants and the if-shape noise-word clauses
pinned as regression guards, parse_status -form absence pinned as GAP.
Also silenced four more unconditional debug puts on get_dict allocation
retreat paths ((111)/(222)/(333)/(444)) - these printed to stderr during
NORMAL successful parses at every optional-skip retreat, polluting
interactive help/parse output for noise-word-modelled commands. Behaviour
unchanged; the retreat logic they marked is exactly this goal fix target.

Probing (punk902z kit, Tcl 9.0.2) of the tclcore moduledoc models against
the real builtins, driven by user concerns about variable-length clauses
with optional elements before G-041 activation. Findings recorded in the
G-041 detail file (auto-selection evidence on real commands, the
allocator prerequisite, parse_status -form gap) and the G-055 detail file
(modelability over-acceptance list: try compound handler types,
reserved-word clause allocation, "-" fallthrough constraints, switch
two-argument option suppression, unvalidated -type expr, TIP 746
version-conditionality for lseq operands; plus the user doc-direction
guidance that definitions split into @form entries where source docs
simplify).
Key result: the per-form models are doc-faithful (lseq.n synopsis maps
1:1; switch separate/block parse correctly under explicit -form; try
mixed on/trap interleaving and finally positioning all agree with the
real command) - but the value allocator mishandles an optional
single-word choice value followed by a required value plus trailing
optional-member clause, so lseq range arglists without the ../to noise
word ("0 10 2", "0 10 by 2") fail in-form. No lseq form accepts them, so
G-041 form selection alone cannot fix "i lseq 0 10 2" - allocator fix
flagged as a candidate prerequisite goal.

New bare @normalize directive: opts a definition into indent normalization
of BLOCK-FORM multi-line field values (first line whitespace-only, as
authored by opening a braced literal with a newline). The structural first
newline and a whitespace-only trailing line are dropped, the content
lines' common leading whitespace is the block's base indent, the first
content line is unindented fully and subsequent lines are re-based to the
standard 4-space continuation convention (deeper relative indents
preserved; whitespace-only inner lines become empty). Fields in a record's
-unindentedfields are exempt. Implemented as a resolve pre-pass over the
split records (private::normalize_records / rebase_multiline_value);
@normalize with options is an error.
Head-form values are never altered - their base indent is unknowable
(continuations uniformly at 6 may be base-4 with the deliberate +2
relative convention, or base-6 flush; re-basing would flatten the former).
The idempotence test caught exactly that on a file-style definition during
implementation, narrowing the user-confirmed re-base semantics to block
form only - which also makes @normalize a proven no-op on conforming
file-style definitions.
Consumer proof (punk 0.2.5, per the recorded user decision):
::punk::helptopic::define_docs converts from interim left-margin authoring
to indented block-form values under @normalize, dropping its
-unindentedfields declarations; 'i help' and 'i help_chunks' verified
aligned in punk902z src, including the blank-line separator in the
combined basehelp+extra block.
Tests: new normalize.test (5 tests: block re-base, block left-margin,
head-form boundary, exemption byte-exactness, file-style idempotence);

An unquoted trailing -& element on a definition record line continues the
record on the next line. Implemented in
private::split_definition_records: the token is dropped and the next line
joins after a single space with its leading whitespace collapsed - exactly
how the Tcl parser joins backslash-newline continuations before a braced
definition ever reaches the splitter - so a -& record assembles
byte-identical to its backslash-continued equivalent. Motivation:
constructed (string-built) definitions cannot author backslash-newline
ergonomically (the building code's own quoting consumes it); -& is plain
text and survives any construction.
Collision rules (analysis and decision recorded in the goal detail file):
bare word preceded by whitespace (or whole line), trailing whitespace
tolerated; braced/quoted -& is data ({-&} escapes a literal trailing
value); mid-line -&, word-suffix abc-&, and -& inside still-open
braced/quoted values are data. Element-count disambiguation rejected
(action-at-a-distance; positional rule is locally decidable). Backslash
authoring unchanged - continuation is additive.

arg_error's cmd-help display transform (undent " "+help, max 4 - the

An argument whose choice pool (-choices plus -choicegroups members,
deduplicated) has 1-3 members and -choicerestricted true (the default) now
renders those words unitalicised joined by | in synopses - e.g 'after cancel'
shows literal cancel, a 3-choice option shows (left|centre|right) - matching
the display style of literal()/literalprefix() type-alternates. Larger or
unrestricted choice sets keep the italicised argname/<type> display, and an
explicit -typesynopsis always takes precedence (textblock::frame -type
unchanged). New shared helper punk::args::private::synopsis_choice_literals
feeds both synopsis render paths (leaders/values via
synopsis_form_arg_display, options inline in synopsis); applies only to
single-element -type lists. Superseded commented-out single-choice sketches
removed; define doc for -choices documents the rule.
tests: synopsis.test 4 -> 13 - characterization coverage for
literal/literalprefix/stringstartswith/stringendswith type-alternates,
option alternate parenthesization, multi-element clause display (?type?
members, argname tail-word hints), -typesynopsis value-element lists and
option passthrough incl documenter ANSI, plus the new choice-literal rule
(leader/option/value positions, choicegroups counting, >3 and unrestricted
fallbacks, -typesynopsis precedence). rendering.test choicelabel fixtures
padded to 4 choices so markercol keeps matching the choices cell rather
than the now-literal synopsis line.
Known residue (deliberate): option-path -typesynopsis ?-trim edge cases
remain (todo comments at the render site) - resolve-time rejection deferred;
any future normalization surgery belongs to punk::ansi::ansistring/opunk::Str.

- tests: parsestatus.test new (12); usagemarking.test G-049 GAP pins flipped + -parsestatus parity/badarg render tests (17); cmdhelp.test G-049 GAP pins flipped + cmdhelp_return_dict_* (25); punk/args + punk/ns trees green on Tcl 9.0.3 and 8.7; full source-tree suite baseline unchanged (exec-14.3 only)
- punkshell 0.5.0: CHANGELOG entry; src/tests/modules/AGENTS.md test-index blurbs updated

Argument resolution no longer tstr-expands display-only content (-help on
@cmd/@examples/argument records, @formdisplay bodies): ${...} there is masked with
inert tokens (spec key DISPLAY_DEFERRED) and expanded at display time via
private::expand_display_fields (hooks in arg_error/eg/resolved_def/@default copyfrom;
separate display cache for non-dynamic defs; @dynamic re-expands per render preserving
provider refresh; reentrancy guard substitutes raw sources when expansion of the same
id re-enters). First parse of heavily documented commands drops accordingly
(punk::ansi::mark_columns first call ~4.3s -> ~12ms; tclcore ::lseq resolve
~184ms -> ~2ms) and -help content that calls punk::args-parsing commands - including
against its own definition id - resolves cleanly instead of stalling or looping.
-choicelabels stays eager (punk::ns reads it from parse specs in the subcommand walk).
Record splitter factored to private::split_definition_records.
Also per G-046 acceptance:
- @dynamic multiline -help substitutions align at the insertion column
(rendering_atdynamic_multiline_help_insertion GAP flipped)
- prefix/alias choice normalization keeps single-element-clause values plain-string
({\Deleted} list-wrap shape bug; choicegroups_imap_prefix_shape GAP flipped)
- -return string renderer aligns cmd-help continuations under the Description: label
(characterization updated) and its Example: line shows the example, not the doc url
- punk::ns cmdhelp shows plain info-scheme usage when no argument words are supplied
for a leader/value-requiring definition ('i string is', 'i punk::args::define') -
advisory parse runs -errorstyle minimal so the discarded error no longer renders a
second usage table (timing parity with pre-change: ~5.3s/4.1s on punk91 src)
Tests: deferredhelp.test (new); suites green on tcl903 + tcl87; full source-tree run
baseline-clean (exec-14.3 only). GOALS.md: G-046 -> achieved 2026-07-10 (activated
this session at user direction); design + verification evidence in the detail file.

First 'i <ensemble>' in a fresh shell (e.g 'i ansistring') rendered the autogenerated
ensemble help without subcommand-help markers/choicelabels: ensemble_subcommands_definition
tested punk::args::id_exists against argdocs whose registered namespace
(::punk::args::register::NAMESPACES) had not yet been lazily loaded - the punk::ns
doc-lookup entry path only loads the ensemble command's parent namespace. The generator
now runs update_definitions for the namespaces its id checks could resolve in.
Self-healed on later calls (autodef regenerates per 'i' invocation), which is why the
defect went unnoticed; no prior test pinned the load ordering.
Tests: punk/args ensembledef.test (new), punk/ns cmdhelp.test

TIP 746 (Tcl 9.1) removed lseq's expr-operand behaviour. punk::lib::range
(lseq branch) now normalizes int[+-]int offsets via offset_expr so callers
like `range 0 [llength $list]-1` keep working (punk::ansi::grepstr broke
under 9.1b0, taking example-block highlighting and the punk::args
examples.test with it). The lseq branch is also aligned with the tcl8
fallback contract: default 'by' now infers direction (descending ranges
previously returned empty under tcl9) and 'by 0' returns empty (Tcl 9.1
lseq changed by-0 to return one element).
Direct lseq expression operands expr-wrapped: punk::lib lzipn_tcl9b/c,
cols, cols2; punk::args zero_based_posns.
check::has_tclbug_safeinterp_compile falls back to interp invokehidden
tcl:unsupported:disassemble - Tcl 9.1 safe interps hide tcl::unsupported::*.
New modules/punk/lib range.test pins the range contract on 9.0 and 9.1;
core tests AGENTS.md documents native-tclsh vs punk-exe exec.test baselines.

Tests-first coverage pass (user-directed) before any changes to the
definition-parsing/indentation machinery. punk/args suite: 128 tests, 15 files.
- rendering.test (15): nesting independence (plain + tstr definitions render
identically regardless of source-block indentation), relative-indent
preservation (2-space help and 1-space choicelabel conventions, single and
multiline - preservation, not enforcement), -unindentedfields (arg -help
works left-margin; @cmd accepts-but-ignores it - GAP pinned), constructed
(string-built) definition absolute-indent characterization ('constructed'
to avoid confusion with the @dynamic directive), multiline ${[cmd]}/${$var}/
resolved_def insertions (aligned at insertion column, nesting-independent),
and @dynamic ${$DYN_X} double substitution: stable across repeated
resolutions, provider refresh honoured in help text, choice display and
parse acceptance, textblock::frame-style art choicelabels byte-aligned -
but multiline -help insertions land lines 2+ at insertion-4 (GAP pinned:
the second-round subst path lacks paramindent re-alignment)
- choicegroups.test (5): group/-choices union parsing, cross-group prefixes,
duplicate-entry dedup, per-group titled choice tables (the punk::imap4
multi-table display), imap4-style {\Deleted}/{$MDNSent} values with labels
incl. through tstr-bearing blocks; GAP pinned: prefix-normalization
list-quotes special-character choices (exact '\Deleted' stores the plain
string, prefix '\De' stores a one-element list) - value shape depends on
input style
- defquoting.test (3): container quoting rules pinned - braced values fully
literal ($, [], two-char \n, bare backslashes), quoted values get Tcl
backslash semantics (\n -> newline, \ -> \) with $/[] still literal, and
\$\{...\} renders a literal ${...} in tstr-processed blocks
- examples.test (6): helpers::example box/title/-tstr toggle (no-dedent
direct-call contract pinned), ${[example ...]} insertion into @cmd help
(bars at insertion column, content +2, automatic 'Example: eg <id>' row),
@examples -> punk::args::eg with #<nodisplay>/@#<nodisplay> stripping
(ANSI-tolerant), strip_nodisplay_lines unit, live tclcore ::lseq smoke
- punk::args 0.3.1: helpers::example -title path called bare [a] (resolvable
only where a punk shell's global alias exists - errored under plain tclsh);
now punk::ansi::a. Found by examples.test in the runtests environment.
- investigated punk::ansi::mark_columns first-call slowness (3.94s first,
60us after): argdoc -help calls a proc that calls mark_columns, whose parse
resolves the same still-resolving definition - hazard already documented
in-source with candidate fixes; recorded in CHANGELOG for goal
consideration, deliberately not patched

Activated and completed under user direction (2026-07-08). Aliases for choice
values are now first-class: accepted at parse, normalized to their canonical
choice in results, folded into the canonical entry in usage display, and
resolved identically by the punk::ns doc-lookup walk.
- punk::args 0.3.0:
* -choicealiases {alias canonical ...} on argument lines; dict shape
validated in the option switch, alias->existing-choice and no-collision
cross-validated after spec merge (surfaces at resolve time - define is
lazy)
* the choice-word matching chain extracted from get_dict into the shared
resolver punk::args::choiceword_match {word nocase allchoices
choicealiases choiceprefix denylist reservelist} -> {matched exact
canonical}; get_dict delegates to it (writeback/lset logic stays at the
call site) - one implementation for parser and doc walk
* exact aliases match under any -choiceprefix/-nocase setting; alias names
join the prefix-calculation pool when -choiceprefix is true; deny applies
to the matched NAME (denied alias requires the full alias; a canonical
reached via its alias is exempt from the canonical's own deny entry)
* display: aliases fold into the canonical entry as an '(alias: x)' /
'(aliases: x|y)' label note (single convergence point covers all render
paths); alias names join the display prefix calculation so highlighted
minimal prefixes stay truthful
* define doc gains the -choicealiases section
- punk::ns 0.1.2: cmd_traverse resolves subcommand words via choiceword_match
- -choiceprefixdenylist/-choiceprefixreservelist now honoured in doc lookup
(the two pinned parity GAP tests flipped to agreement), aliases normalize
before choiceinfo lookup, -nocase honoured in the walk
- punk 0.2.3: punk::help adopts the feature - 'i help' lists one entry per
registered topic (topics+help, tcl, env+environment, console+term|terminal);
topic words accept aliases and unique prefixes with the user-decided
minimum-prefix policy recorded in ::punk::helptopic: denylist {help}
(h/he/hel stay command words), reservelist {c to tc} (fall through to
command lookup; e/en and te/ter fall through naturally as ambiguous).
Argless 'help' output byte-identical to the strict-80 baseline.
- tests: choices.test +5 (alias exact/prefix normalization, noprefix exact-
only, nocase, the punk::help policy matrix, resolve-time validation);
cmdflow.test parity tests flipped from GAP to agreement + alias-traverse and
display-fold assertions (+flowaliased fixture)
- suites: punk/args 98 pass + 1 skip, punk/ns 28 pass, punk/lib 21 pass
- G-040 flipped active -> achieved 2026-07-08; detail file records
implementation and verification
- project 0.4.10 (CHANGELOG entry)

- fixed "@opts -any 1" (arbitrary/adhoc option passthrough): an option not in
the definition crashed get_dict with "can't read argname" at the name-mapping
stage - adhoc opts now fall back to their raw supplied name, under which
argstate/arg_checks were already populated at scan time (real consumers:
vendored tomlish definitions declare -any 1)
- commented out a debug puts stderr (">>>_get_dict_can_assign_value NOT
alloc_ok...") that fired on every failed clause type assignment (visible on
any multiform parse miss; its happy-path twin was already commented)
- new forms.test (8 tests): @form spec structure (form_names, shared
{a b}-prologue blocks), explicit -form by name/index with cross-form
rejection, multiform synopsis rendering, and GAP pins for G-041 - default
parse is effectively form-0-only, -form rejects the documented list-of-forms
usage, and @form -synopsis overrides are stored in the spec but ignored by
synopsis rendering
- new validation.test (11 tests): -type validation matrix, -range/-minsize/
-maxsize, -nocase choice normalization, option -multiple accumulation,
required-option enforcement, unknown-option rejection vs -any adhoc
passthrough (the bugfix's regression test), -- end-of-options marker,
@values -max enforcement, received-key clause ordinals, solos list, and
default-vs-received distinction
- src/tests/AGENTS.md: note that tcltest compares the -body return value -
bodies ending in a loop must end with an explicit 'set result'
- suites: punk/args 93 pass + 1 skip (was 70+1), punk/ns 18 pass; full
source-tree run 569/581 with only the known exec-14.3 baseline failure

- GOALS.md: G-040 punk::args choice aliasing with parse normalization, display
folding, and doc-lookup parity (user-approved); detail file records the
prefix/deny/reserve collapse analysis from the punk::help work, the
cmd_traverse divergence, the c/to/tc minimum-prefix policy question, and the
test-first sequencing
- new punk/ns cmdflow.test (10 tests): cmdwhich/cmdinfo/cmd_traverse docid
flow - direct, via-alias and subhelp-choiceinfo resolution (exact + unique
prefix), unknown-word fallback to parent docid, -choiceprefix 0 exact-only,
space-delimited ids, cmdhelp -return string smoke; the parse-vs-doc-walk
divergence (deny/reserve lists honoured by punk::args::parse, ignored by the
cmd_traverse walk) pinned as GAP tests pending G-040
- choices.test: 4 new unrestricted-mode (-choicerestricted 0) tests - prefix
normalization to the canonical choice, unknown/ambiguous passthrough,
denylist and reservelist passthrough, and the punk::help collapse recipe
(prefix+deny+reserve on a -multiple leader)
- punk::args 0.2.2 (doc-only): define doc -choice* fields now state the
-choicerestricted 0 passthrough semantics, -choiceprefix result
normalization + minimal-prefix display highlighting, denylist behaviour for
shorter prefixes in both restricted modes, and the reservelist phantom-entry
idiom for per-choice minimum-prefix control
