* test(3594): adversarial parser fixtures + frontmatter/roadmap matrix + property-style suite
Lands the adversarial parser-input corpus that CONTRIBUTING.md
§"QA Matrix Requirements / Parser and project-file inputs" and
TEST-EXAMPLES.md §"Parser Adversarial Fixtures" describe.
New tests/fixtures/adversarial/ layout:
frontmatter/
duplicate-keys.md — same key twice (collapses last-wins)
crlf-mixed.md — CRLF endings throughout
unclosed-block.md — `---` open with no close
unicode-keys-and-values.md — non-ASCII + emoji + Greek
null-byte-value.md — U+0000 in a value
huge-bounded.md — 2000-item array, ~30KB
roadmap/
phase-heading-inside-fenced-code.md — #2787 fence shadowing
nested-fenced-code.md — outer + inner ``` blocks
unicode-phase-titles.md — JP / Greek / emoji titles
repeated-phase-ids.md — phase 1 declared twice
decimal-phase-mixed.md — 2 vs 2.1 vs 2.10 vs 21
markdown-headings-inside-html-comment.md — comment shadowing
Test files (all node:test, no try/finally in test bodies, no source-grep,
no raw-text matching on stdout/file content):
tests/feat-3594-parser-adversarial-frontmatter.test.cjs (12 tests)
Loads each fixture, pins parser invariants on extractFrontmatter()
return shape. Cross-corpus "does not throw on any fixture" sweep.
tests/feat-3594-parser-adversarial-roadmap.test.cjs (18 tests)
Loads each fixture into a temp project's .planning/ROADMAP.md and
drives `gsd-tools roadmap get-phase <N>` via the runCli harness
introduced by #3593. Asserts on the typed JSON payload.
tests/feat-3594-parser-property-style.test.cjs (2 tests)
Deterministic mulberry32 PRNG generates 500 malformed-ish
frontmatter inputs per test. Pins (a) extractFrontmatter is total
over the corpus (no null-deref TypeError, always returns a plain
object on success), (b) the suite completes well under 2 seconds
(quadratic-regression guard).
Known-open bugs surfaced and pinned (intentionally NOT fixed in this
PR — separate issues warranted):
- CJS roadmap parser matches `## Phase N:` headings inside fenced
code blocks (the SDK parser tracks fences per the #2787 comment in
sdk/src/query/roadmap.ts but the CJS path has not caught up).
- CJS roadmap parser matches `## Phase N:` headings inside HTML
comments.
Both are documented in-test with the "currently STILL matches it
(open: needs <fix>)" naming pattern so the day the production fix
lands, flipping the assertion from `found: true` to `found: false` is
the regression guard.
Test totals:
- 32 new feat-3594-* tests (12 frontmatter + 18 roadmap + 2 property)
- 108/108 pass when running together with the pre-existing
frontmatter.test.cjs + roadmap.test.cjs suites (76 of theirs).
Closes#3594

* test(3594): use Fisher-Yates shuffle for deterministic seeded inputs
Replaces `arr.sort(() => rng() - 0.5)` with a Fisher-Yates shuffle
driven by the supplied PRNG. The sort-based shuffle is non-transitive:
V8's TimSort behavior on non-transitive comparators is engine-defined,
so the same seed produced different orderings across Node versions —
undermining the test's stated reproducibility guarantee.
Fisher-Yates is O(n), transitive (no comparator at all), and consumes
exactly n-1 RNG values in a fixed order. The mulberry32 seed now
determines the input sequence end-to-end.
