fix(archive): preserve blank lines inside code fences - #1798
Conversation
📝 WalkthroughWalkthroughThe spec retirement audit now recognizes wrapped and nested list content and structural boundaries. Spec rebuilding collapses blank-line runs only outside fenced code blocks. Tests cover fenced and unfenced behavior, and a patch changeset documents the fix. ChangesSpec processing

An edge-case inconsistency in list-marker parsing may affect retirement auditing for unusual Markdown list formatting, but presents bounded low risk.

Reviewed the fence-aware normalization and ran the focused 8-test suite locally. It preserves fenced content while retaining the prior behavior outside fences. Approved.
The fix changes archive output for any spec documenting a fenced sample with consecutive blank lines, so it belongs in the changelog. Release tracking only validates changesets that exist; it never requires one, which is why CI stayed green without it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Reviewed 97dbdfc. The changeset accurately tracks the fence-aware archive fix, all 8 focused tests pass, and CI is green.

LIST_ITEMwithINTERRUPTS_PARAGRAPHon marker spelling.The doc comment states that a shared definition prevents the audit and
INTERRUPTS_PARAGRAPHfrom disagreeing about what a marker is. The two patterns still disagree in two cases:
LIST_ITEMrequires\s+after the marker, so a marker-only line such as-or1.does not match.INTERRUPTS_PARAGRAPHmatches it through(?:[ \t]|$). The comment claims content after the marker is not required, but only-with a trailing space matches.LIST_ITEMallows unlimited leading whitespace through\s*, whileINTERRUPTS_PARAGRAPHallows{0,3}. A line indented four or more columns is read as a list item that opens a new content column, so following indented lines are absorbed as continuation.Both differences only shift audit verdicts on edge cases, so this is a consistency fix rather than a functional defect.

Why
The final assembly in
buildUpdatedSpecnormalises blank lines across the wholerebuilt document:
That normalisation exists to tidy the seams between the four slices being
rejoined, but it also rewrites the inside of fenced code blocks. A requirement
documenting a sample with two or more consecutive blank lines has that sample
silently edited on archive, and re-edited on every subsequent archive.
It matters for whitespace-significant content — YAML block scalars, Python,
expected-output fixtures, Markdown-in-Markdown examples. Every other structural
pass in this module is already fence-aware via
buildCodeFenceMask; this onewas not.
What Changes
collapseBlankRunsOutsideFences, whichwalks the assembled document with
buildCodeFenceMaskand collapses blankruns only outside fenced blocks.
line counts as blank, exactly as
/\n{3,}/did, so a line of spaces is stillnever a collapse boundary.
Testing
test/core/specs-apply.fence-preservation.test.ts— 8 tests, written first andwatched fail (5 failed / 3 passed before, 8 passed after).
Edge cases covered:
~~~) fence\n{3,}survives)against the full expected string, not a substring)
delta) are preserved
Full suite green on this branch.
Changeset
Not added. Per
.changeset/README.mdthe default path is the normal releasecadence; happy to run
