test(harness): move JD-archive wiring out of test-all.mjs + catch rebound write APIs - #4159
Conversation
career-ops#3935: test-all.mjs is the central harness every check runs through, and section 75 was a suite living inside it rather than under tests/, contrary to this repo's own convention (.coderabbit.yaml path instruction: new numbered sections belong in tests/ files) and precedent (career-ops-hq#3863 moved the context-budget suite the same way). Moved verbatim to tests/jd-archive-wiring.test.mjs, following the same pass/fail-from-helpers.mjs style as context-budget.test.mjs (the issue's own suggested shape). test-all.mjs's readFile() helper became a local readFileSync(join(ROOT, path)) — the only behavior it added beyond a plain read (following a single-line '..' redirect file) is not used by any of the files this suite reads. No assertion changed; test-all.mjs's own auto- discovery of tests/*.test.mjs picks the suite up with no registration. node test-all.mjs: 8726 passed, 0 failed — same as before the move, and the 13 JD-archive assertions still run (confirmed in the output, now printed without a section number since it's a standalone suite).

…fs API
career-ops#3936: the by-name call scan ('does this line contain
writeFileSync(?') is blind to a local re-binding — 'const write =
writeFileSync; write(dest, data)' never contains the literal substring
'writeFileSync(', so a write through the alias sits outside runSelfTest
invisibly. Verified both shapes against the check's own logic (from the
issue): an import-time alias ('writeFileSync as wfs') is already rejected by
the import-list check, since that exact string isn't in either allowed set;
a LOCAL re-binding created in the file body is the one gap.
Flags the alias's creation (const/let/var NAME = <write-capable-fn>) outside
runSelfTest, not just a subsequent call through it — holding the capability
outside the self-test boundary is the violation regardless of whether the
alias is ever invoked.
Mutation-verified: injecting 'const sneakyWrite = writeFileSync;' right after
the fs import (outside runSelfTest) is caught; reverting it passes clean.
This depends on career-ops-hq#4159 (which creates tests/jd-archive-wiring.test.mjs — the
file did not exist as an independent target on main before that move), so
it rides the same branch/PR as a second, separately-attributed commit rather
than one that can't find its file on a fresh main.
node test-all.mjs: 8727 passed, 0 failed.

I reviewed the new owned suite tests/jd-archive-wiring.test.mjs. The move preserves the coverage and actually strengthens it, and the suite genuinely runs.
I diffed what was removed from the harness against the new file: all 13 assertions from the old block are reproduced (SYSTEM_PATHS, the npm script, SCRIPTS.md, AGENTS.md x2, oferta.md x2, pdf.md x2, the fs-import boundary, the no-write-outside-self-test guard, no fs/promises, no require), nothing dropped or weakened, and the brace-walk self-test-body extraction from the earlier CodeRabbit fix is intact. The move adds a 14th assertion (#3936) that catches a local re-binding of a write-capable fs API (const x = writeFileSync), which the by-name call scan was blind to. It reads the real check-jd-archive.mjs, update-system.mjs, package.json, docs/SCRIPTS.md, AGENTS.md, modes/oferta.md, and modes/pdf.md, so it drives the same real wiring the old block did, not a reconstruction.
It runs in CI: node test-all.mjs --only jd-archive-wiring discovers and executes it (14 passed, 0 failed), and there is no process.exit( in the file, so it clears the static guard that would otherwise refuse it. I mutation-checked it: dropping check-jd-archive.mjs from SYSTEM_PATHS reddens, dropping the jd-archive npm script reddens, and injecting a const evilWrite = writeFileSync outside the self-test reddens the new #3936 assertion, all green again on revert.
One known limit, carried over from the original block rather than introduced here: the SYSTEM_PATHS and npm-script checks are substring assertions, so commenting the line out (as opposed to deleting it) would not redden them. Not a regression from this move, but now that the assertions live in a dedicated suite it would be a touch stronger to assert on the parsed value rather than a substring, so a commented-out registration is caught too.
On my machine I have the targeted suite green (14/0) and CI is green on ubuntu and macos at this head; the full local test-all run and the windows check were still in flight when I looked, so I am not claiming those. Owned suite sound, coverage preserved. The test-all.mjs side of the move is the shared harness, outside my area, so I am speaking only to the new suite.
CodeRabbit on career-ops-hq#4159: const write = (writeFileSync); is still a rebinding, but the prior pattern (=\s*NAME\b) never matched it — the opening paren sits between the = and the name. Allowed zero or more wrapping parens (with optional inner whitespace) around the captured name. Also adds a direct fixture test for REBIND_RE itself: the real check-jd-archive.mjs has no rebinding to exercise the positive case against, so the existing check can only ever prove the negative ('the real file is clean'). Six cases — bare, single- and double-parenthesized, parenthesized with inner spaces, a longer identifier merely prefixed by the name (must NOT match), and the name passed as a call argument rather than assigned (a different code shape, must NOT match). Mutation-verified: reverting to the pre-fix pattern reddens exactly the three parenthesized-initializer fixture cases; the bare and negative cases stay green either way, and restoring the fix turns all fifteen assertions in the file green again. node test-all.mjs: 8728 passed, 0 failed.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Detect $-prefixed write aliases
At tests/jd-archive-wiring.test.mjs:158, \w+ does not match $. Therefore, const $write = writeFileSync; $write(...) bypasses both the rebinding assertion and the literal-call assertion. Extend the binding pattern and add a fixture for this valid alias form.
Proposed fix
- const REBIND_RE = /\b(?:const|let|var)\s+\w+\s*=\s*\(*\s*(mkdtempSync|mkdirSync|writeFileSync|rmSync)\s*\)*\b/g;
+ const REBIND_RE = /\b(?:const|let|var)\s+[$A-Za-z_][$\w]*\s*=\s*\(*\s*(mkdtempSync|mkdirSync|writeFileSync|rmSync)\s*\)*\b/g;+ ["const $write = writeFileSync;", true, '$-prefixed alias'],📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Fixes #3935, fixes #3936.
#3935 — move section 75 out of test-all.mjs
test-all.mjsis the central harness every check runs through, and section75 ("JD-archive validator wiring + read-only boundary (#2789)") was a suite
living inside it rather than under
tests/— contrary to this repo's ownconvention (
.coderabbit.yamlpath instruction: new numbered sections belongin
tests/files) and precedent (#3863 moved thecontext-budgetsuite thesame way).
Moved verbatim to
tests/jd-archive-wiring.test.mjs, following the samepass/fail-from-helpers.mjsstyle ascontext-budget.test.mjs. Noassertion changed.
test-all.mjs'sreadFile()helper became a localreadFileSync(join(ROOT, path))— the only behavior it adds beyond a plainread (following a single-line
..redirect file) isn't used by any of thefiles this suite reads.
#3936 — catch a local re-binding of a write-capable fs API
The by-name call scan ("does this line contain
writeFileSync(?") is blindto a local re-binding —
const write = writeFileSync; write(dest, data)never contains the literal substring
writeFileSync(, so a write through thealias sits outside
runSelfTestinvisibly. An import-time alias(
writeFileSync as wfs) is already rejected by the existing import-listcheck; a local re-binding created in the file body was the gap.
Added a check that flags the alias's creation
(
const/let/var NAME = <write-capable-fn>) outsiderunSelfTest, notjust a subsequent call through it — holding the capability outside the
self-test boundary is the violation regardless of whether the alias is ever
invoked.
This rides the same branch as #3935 (as a second, separately-attributed
commit) because it depends on the file #3935 creates —
tests/jd-archive- wiring.test.mjsdidn't exist as an independent target on a freshmainbefore that move.
Verification
node test-all.mjs: 8727 passed, 0 failed — the 13 original JD-archiveassertions plus the new rebinding check, all passing; and separately,
mutation-verified by injecting
const sneakyWrite = writeFileSync;outsiderunSelfTestand confirming the new check catches it, then reverting clean.Summary
Moved the JD-archive validator wiring suite to
tests/jd-archive-wiring.test.mjs:20.User impact
The suite now runs through automatic test discovery and preserves its
pass/failbehavior.The read-only boundary check now detects local rebindings of write-capable filesystem APIs, including parenthesized initializers. It excludes longer identifiers and unrelated call arguments.
Files changed
test-all.mjs: Removed section 75.tests/jd-archive-wiring.test.mjs: Added wiring, documentation, and read-only boundary checks.The checks cover
AGENTS.md,modes/oferta.md,modes/pdf.md,update-system.mjs,package.json, anddocs/SCRIPTS.md.DATA_CONTRACT.md,providers/, and.github/were not changed.Verification
Passed: 8,728 tests.
