fix(qa): CRLF page parsing on Windows (#282) and long-term reject-code drift (#283) - #299
Conversation
Six frozen-page tests failed on windows-latest and passed on macOS. Git
converts the fixtures to CRLF on a Windows checkout, and the page parser
split on "\n" alone, so every line kept a trailing \r. parsePage matches
marker VALUES exactly, so `**Type:** Menu` arrived as "Menu\r", no entry
ever found its Type, and the parse threw:
partitions.md: entry "/partitions" at line 10 has no Type marker
Reproduced locally by feeding the committed fixtures through
.replaceAll("\n", "\r\n") — same error string as CI.
Every line-splitting consumer (parsePage, countTypeMarkers, countRowMarkers)
routes through pageBody, so normalizing there fixes all of them at one
point: split on /\r?\n/, rejoin with "\n". Line endings ONLY — every
fail-loud check downstream is untouched, so a page whose format really moved
still throws.
countTypeMarkers survived CRLF by accident, because it prefix-matches
/^\*\*Type:\*\*/ where a trailing \r does not reach. That is why the marker
reconciliation could not catch this on its own.
Adds two guards: a CRLF-vs-LF parse-identity test over all three frozen
pages (which covers preamble, headings, Type/gate markers, ArgTable rows and
both reconciliations at once, and keeps covering them as fixtures change),
and one proving an unknown Type on a CRLF page still throws. Both verified
to go red with the fix reverted and green with it.

…fting assertions (#283) The long-term CHR leg failed on 7.21.5 in execute.test.ts and mcp.test.ts: RouterOS names the offending parameter only from 7.23 (`bad parameter`, via /console/inspect) → validation/unknown-attribute, while ≤ 7.21.x rejects generically at the :parse gate first → validation/syntax. Both are correct "rejected before anything ran" outcomes, which is what these examples prove. Both now use VALIDATION_REJECT_CODES, already exported from chr.ts and already used by the rest-api twin at execute.test.ts:205 — these two sites were simply missed. Scoped deliberately to those two. Four other integration files hard-code validation/unknown-attribute (api.test.ts, api-native.test.ts, rest-retrieve.test.ts, native-api-retrieve.test.ts); all four RAN and PASSED on the same 7.21.5 leg, so they are a different signature, not this drift. Relaxing them would weaken live assertions for no reason. The modern-side richness is not lost: execute.test.ts:219 still asserts the parameter name conditionally when the code is unknown-attribute. Verified on real CHRs, mcp.test.ts + execute.test.ts: - 7.21.5 long-term 3/3 (was 1 pass / 1 fail, twice, including the retry) - 7.23.3 stable 3/3 — 110 expects vs 109 on long-term, the conditional parameter check firing only on the modern device Fixes #283 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Pull request overview
This PR aims to restore a green qa.yaml gate by fixing two independent CI failures: Windows CRLF line-ending parsing in the explain catalog frozen-page parser (#282) and version-dependent validation reject-code drift in CHR integration tests (#283).
Changes:
- Normalize CLI-Reference page parsing to handle CRLF checkouts by splitting on
\r?\nand rejoining with\ninpageBody()(#282). - Add CRLF regression tests to ensure LF/CRLF parsing behavior is identical and that unknown-format failures remain fail-loud (#282).
- Update two CHR integration assertions to accept the shared
VALIDATION_REJECT_CODESset instead of hard-codingvalidation/unknown-attribute(#283).

review) Both bots caught the same real defect, and it was worse than minor: on a Windows checkout readFixture already returns CRLF, so replaceAll("\n","\r\n") produced "\r\r\n". `/\r?\n/` consumes one \r and leaves the other on every line, so the new regression test would have failed on the exact platform it exists to protect — for a reason having nothing to do with the parser. Normalize with .replace(/\r\n?/g,"\n") first, and assert the normalized copy carries no \r so the setup cannot silently regress. Demonstrated rather than reasoned: rewriting the three frozen fixtures as CRLF on disk (a genuine autocrlf checkout, not a synthetic in-memory string) fails the pre-review test 1/60 and passes 60/60 with this fix.

Fixes #282. Fixes #283.
The two remaining
qa.yamlfailures after #298 landed — thewindows-latestunit leg and the must-passlong-termCHR leg — in one PR because they are both "turn the QA gate green" and neither touches the other's files. One commit per issue; say the word and I'll split them.Baseline: QA run 31833917384 on
main@df94bdf, which already includes #296's gating.explain-valuesno longer appears in the failure list, which is the controlled confirmation that #298 worked and that what remains is a different signature.#282 — Windows CRLF, 6 tests (
explain/catalog — parsing published pages)Git converts the frozen fixtures to CRLF on a Windows checkout. The page parser split on
"\n"alone, so every line kept a trailing\r— andparsePagematches marker values exactly, so**Type:** Menuarrived as"Menu\r", no entry ever found its Type, and the parse threw:Reproduced locally by feeding the committed fixtures through
.replaceAll("\n", "\r\n")— same error string as CI, so this needed no Windows box to confirm.Every line-splitting consumer —
parsePage,countTypeMarkers,countRowMarkers— routes throughpageBody, so normalizing there fixes all of them at a single point: split on/\r?\n/, rejoin with"\n". Line endings only. Every fail-loud check downstream is untouched, so a page whose format genuinely moved still throws.Worth recording:
countTypeMarkerssurvived CRLF by accident, because it prefix-matches/^\*\*Type:\*\*/where a trailing\rnever reaches. That is precisely why the marker reconciliation could not catch this on its own.Two guards added:
parses a CRLF checkout identically to LF— asserts the CRLF parse equals the LF parse across all three frozen pages. Identity (rather than "both non-empty") is what covers the whole surface the AC lists — preamble, headings, Type/gate markers, ArgTable rows, both reconciliations — and keeps covering it as the fixtures change. It also re-asserts both reconciliations hold under CRLF, since two equally broken parses would also be equal.still refuses an unknown Type when the page is CRLF— the AC's "do not weaken unknown-source-format failures".Both were mutation-tested: reverting only the one-line fix turns both red, and restoring it turns them green.
#283 — long-term reject-code drift, 2 assertions
RouterOS names the offending parameter only from 7.23 (
bad parameter, via/console/inspect) →validation/unknown-attribute; on ≤ 7.21.x the:parsegate rejects generically first →validation/syntax. Both are correct "rejected before anything ran" outcomes, which is what these examples exist to prove.Both sites now use
VALIDATION_REJECT_CODES— already exported fromchr.ts, already used by the rest-api twin atexecute.test.ts:205. These two were simply missed:test/integration/execute.test.ts:368(native-api twin of the already-converted rest-api case)test/integration/mcp.test.ts:149(example 4)Scoped deliberately to those two. Four other integration files hard-code
validation/unknown-attribute—api.test.ts,api-native.test.ts,rest-retrieve.test.ts,native-api-retrieve.test.ts. All four ran and passed on the same 7.21.5 leg, so they are a different signature rather than this drift, and relaxing them would weaken live assertions for no reason. Reading #283's first AC as "convert every site" would have masked four working tests.The modern-side richness is not lost:
execute.test.ts:219still asserts the parameter name conditionally when the code isunknown-attribute.Validation
Real CHRs, Intel Mac, HVF, quickchr 0.4.7,
mcp.test.ts+execute.test.ts:bun test2854 pass (+2 new CRLF guards),bun run lint:ciandbun run buildclean.The Windows leg itself still needs CI to confirm, since the repro here is a synthetic CRLF conversion rather than a real Windows checkout — that is what the
windows-latestjob in this PR's run proves.Summary by CodeRabbit
