//
// A live/archived split on `parse_gap_files` was tried in this branch and
// reverted (#3707 follow-up, #2766's own rationale): "Outstanding UAT items do
// not stop mattering when a milestone closes: a deferred human-UAT scenario or
// a `skipped` live-stack test is exactly what gets archived still-open." So
// "archived UAT files are complete by definition" — the split's premise — is
// false, and `total_items` (`summary.total_items`) has never had such a split
// either. Two regressions were executed under the split:
//   (a) a phase belonging to the CURRENT milestone, but filed under
//       `.planning/milestones/<version>-phases/` (getArchivedPhaseDirs scans
//       that whole tree regardless of which milestone ROADMAP.md currently
//       names), was classified "archived" and demoted out of the gate —
//       live in-progress work reported as closed history.
//   (b) an archived outstanding row that PARSES gives `total_items: 1` and
//       trips Verification Debt; the SAME row made unparseable gave
//       `parse_gap_files: 0` under the split — the parse failure buried the
//       debt, the exact bug class #3707 exists to fix.
// `parse_gap_files` now counts EVERY entry with `parse_gap: true`, unfiltered
// by `archived_milestone` — mirroring `total_items` exactly.

// and declared the class closed. It was not: `parseVerificationItems`
// (VERIFICATION.md) and `parseDeferredItems` (deferred-items.md) are reached
// from the SAME function via their own, separately unnormalized
// `fs.readFileSync` calls, so a lone-CR VERIFICATION.md or deferred-items.md
// hit the identical total false-clean this issue exists to close. The fix
// this time is at the READ BOUNDARY (`readNormalizedDocument` in
// src/uat.cts), not per-parser — these tests drive the full CLI end-to-end so
// they exercise that boundary, not a parser function directly.

// #3078-CR: a column-0 line-terminator boundary defect in

// LIVE built copy (`../msd-core/bin/lib/uat.cjs`, imported at the top of this
// file) rather than through a rebuilt fixture, so these rows fail against the
// ACTUAL shipped parser, not a stale mental model of it.
//
// DEFECT A (fixed): `/^result:.../im` treats U+2028 LINE SEPARATOR and U+2029
// PARAGRAPH SEPARATOR as line-start boundaries (native JS `/m` behaviour),
// but `normalizeLineEndings` (core-utils.cjs) folds only `\r`/`\r\n` and never
// touches U+2028/U+2029, and neither does `split('\n')` or the heading
// tokenizer. A `result:`-shaped line living INSIDE an `expected: |` scalar
// body, immediately after one of these separators, was therefore read as a
// real line start by the regex engine and — because `.match()` without `/g`
// returns the LEFTMOST match in the whole string — won over a genuine
// column-0 `result:` line appearing later, discarding it with no gap raised.
// Fixed by testing each `split('\n')`-produced line individually instead of
// running an `/m`-anchored regex over the whole block: `split('\n')` never
// treats U+2028/U+2029 as a delimiter, so neither can manufacture a line
// start.
//
// A "defect B" (more than one column-0 `result:` line reported as an
// ambiguous parse gap rather than resolving to the first) was attempted and
// REVERTED: its boundary-truncation heuristic mistook an indented `### N.`
// living inside a legitimate block scalar for a heading boundary, which
// broke every scalar/indent guard this module has (see the `#3078` scalar
// guard tests elsewhere in this file). Two column-0 `result:` lines resolve
// to the FIRST one — the pre-existing, pinned behaviour — see controls B3/B4
