* test(#4134): fail-first regression — refuse punctuation-fragment milestone names
A first-milestone ROADMAP.md H1 that puts the version after the name
(# Roadmap: Project — Name (v1.13)) leaves exactly ')' after the heading's
own version token, which the ADR-3180 §7.2 pinned name rule returns as a
COMPLETE-scope milestone name. Failing-first coverage:
- getMilestoneInfo: name-then-version H1 (STATE-anchored + ROADMAP-only
fallback) must yield TRUNCATED {version, name: null}, never ')'
- the refusal is level-agnostic (H2/H3)
- punctuation-family remainders (')', '()', '**', '.,;:', ']}', emoji-only)
- listMilestoneHeadings enumerates the heading with name: null
- init manager CLI reports milestone_name: null and no lone ')' anywhere
- property (seed 20260905, 300 runs): a word-char remainder is always a
name, a punctuation-only remainder never is
- negative space: canonical delimiter forms, parenthetical names (#3171),
trailing markers, digit-only names, CRLF headings, version-last-no-parens
control
* fix(#4134): refuse punctuation-only milestone heading names
extractMilestoneHeadingName returns everything after the heading's own
version token as the name (ADR-3180 §7.2 pinned rule), which assumes
version-then-name. A name-then-version heading — the H1 a first-ever
ROADMAP.md drifts into ('# Roadmap: Project — Name (v1.13)') — leaves
exactly ')' after the token, and that fragment was returned as a
COMPLETE-scope milestone name, propagating into init.* JSON output and
buildStateFrontmatter's STATE.md writes.
A remainder with no letter or digit anywhere (any script) is heading
structure, not a curated name: refuse it as name: null so callers report
the honest §7.2 rule-6 answer (version kept, TRUNCATED scope). Names
that merely contain punctuation are unaffected — '(' stays an ordinary
name character (#3171) — and digit-only names qualify.
Also closes the template gap that lets the shape occur: the roadmapper
agent's output_formats now templates the version-free canonical H1
('# Roadmap: [Project Name]', per templates/roadmap.md) instead of
leaving a first milestone's title line to invention. The new section
shifts the file's existing bare-gsd-tools prose mention from line 647
to 660, so its line-keyed PROSE_ALLOWLIST entry moves with it.
Emitted-Drift-Ack-Growth: gsd-roadmapper.md — deliberate +498 bytes: new '### 0. Top-Level Title (H1)' output_formats section templating the canonical version-free H1, closing the first-milestone template gap that lets an H1 drift into 'Name (vX.Y)' and corrupt milestone_name extraction (#4134)
