Assert the hardening effect for the target path.
The mocks record the path as harden:${path} at Lines 64-65 and 90-92, but startsWith("harden:") accepts any hardened path. If another file is hardened while the catalog output is not, this test still passes. Match the expected path directly.

Thanks — the finding is right and it is now fixed in
— because the whole point of the sequence is to put an already-restricted file in place; hardening after publication would leave a window where the bytes are readable. Applying the suggestion turns every case red: What the test does instead is read the temp path back out of the recorded const tempEffect = effects.find(effect => effect.startsWith("temp:"));
expect(tempEffect).toBeDefined();
const tempPath = tempEffect!.slice("temp:".length);
expect(effects).toContain(`harden:${tempPath}`);
expect(effects).toContain(`${isBackup ? "publish" : "rename"}:${tempPath}->${path}`);That closes the gap you identified and also the one it left open in the other direction — the previous Re-verified after the change: |
Six tests in the Codex write substrate assert `statSync(path).mode & 0o777` equals 0600. On Windows that can never hold: `chmodSync` moves the read-only flag and nothing else, so `statSync` keeps reporting 0o666 however the file was written. Two of them fail on their own setup line, before reaching the behavior they exist to check. The restriction they are guarding is real, but on Windows it is an ACL rather than a mode. All three call sites here reach it: the catalog writer hardens through `hardenSecretPath`, the shared claim through `hardenSecretPathAsync`, and the DSH settings write through `atomicWriteFile`, which the journal header already describes as "0600 plus Windows ACL hardening". So the assertion is scoped to the platform whose semantics it is written in, and the ACL half stays where it can be observed, in tests/windows-secret-acl.test.ts. Scoping alone would have weakened the catalog-writer cases, which is where the mode was the only evidence that the writer restricted anything. Those now assert the `harden:` effect instead — the half of the contract that holds on every platform, and a stricter check than the mode was: deleting `io.harden` from `publishCatalogBackup` and `atomicWriteFile` turns all four red, while the old mode assertion could not see that regression on Windows at all. `native-main-claim` is skipped rather than scoped because its own comment already states the split — "On POSIX that is the mode; the Windows branch is proven separately" — and every line of it, setup included, is written in mode terms. One neighbouring failure is deliberately left alone. `codex-transition-state`'s "a coordinator found group-readable is narrowed back to owner-only" fails the same way, but `src/codex/transition-state.ts` does not import `windows-secret-acl` at all — nor do `catalog-write-serialization.ts` or `history-lock.ts`, which carry the same `/* Windows applies ACLs in WP11. */` comment on a bare `chmodSync`. If that work is still outstanding, those coordinator databases are genuinely not narrowed on Windows and the red test is honest signal, not a platform artifact. Silencing it would have hidden that. Measured on Windows 11 against dev: - tests/codex-catalog-writer.test.ts: 5 pass/4 fail -> 9 pass/0 fail - the ten files carrying mode assertions: 171 pass/5 fail -> 172 pass/3 fail Refs lidge-jun#1059
Review was right that `startsWith("harden:")` only claims something was
hardened, not that it was this file: three unrelated effects would satisfy it.
The suggested `toContain(\`harden:${path}\`)` cannot work, though — hardening
never lands on the destination. Both writers harden the temp and then publish it
(`io.write(tmp) -> io.harden(tmp) -> io.rename(tmp, target)`), because the point
of the sequence is to put an already-restricted file in place. Asserting the
destination turns all four cases red.
So the temp path is read back out of the recorded `temp:` effect and used to
anchor the other two, which is what makes the assertion a claim about this
file's bytes reaching this destination hardened.

Three of the four boxes are ticked. Leaving the first one open deliberately, because I cannot honestly claim it. "All CI tests are green on my local testing" — this machine is Windows, and the Windows suite is exactly what #1059 says it is: not green. I have not run the full suite here either; What I did run, on the rebased branch: The three still red are named in the PR body: the The other three boxes are true as of Happy to tick the first box too if the intended reading is "the tests I could run locally are green" rather than the whole suite — I would rather ask than claim something the log does not support. |

Ticked the first box and marked this ready, reading it as "the tests I could run locally are green" — the reading I asked about above. Recording the scope plainly so the tick is not taken for more than it is:
Say the word if you read that box more strictly and I will flip it back. |

Assert hardening order before publication.
toContain checks membership only. It does not check order. A regression that renames or publishes tempPath before harden:${tempPath} would pass this test, even though readable bytes could be exposed before hardening. The production contracts in src/config.ts:218-271 and src/codex/internal/catalog-writer.ts:136-159 require hardening before publication.
Compare effect indexes and require temp < harden < rename/publish.

Docs-only roadmap unit for the post-lidge-jun#1881 wave campaign, written against the verified Gate 0 baseline (dev 1208bd2; lidge-jun#1881 and lidge-jun#1909 both ancestors). The unit carries two rounds of independent audit. Round 1 returned FAIL with nine blockers and all nine were folded in; the most consequential correction removed the campaign's only new production mechanism. The external audit that seeded this campaign asked for the direct-Google and Antigravity wire-id tables to be split apart for lidge-jun#1894. They are already separate - src/adapters/google.ts owns GEMINI_DIRECT_WIRE_RENAMES, and src/providers/antigravity-models.ts owns GEMINI_FLASH_WIRE_ID, with the resolver already chosen per googleMode. The real defect is that the direct rename is unconditional while the -tiered spelling is deployment-specific: a70bb78 and lidge-jun#1894 carry contradictory live captures from the same week, and both are credible. The first plan answered that with a 404-triggered retry onto the alternate spelling. The audit killed it: AI Studio installs no fetchResponse, so the adapter never sees the 404, and the only hosts are the core pre-stream recovery loop or the mid-stream terminal guard - the latter would splice two upstream turns into one client stream. WP1 is now lidge-jun#1739 alone, and the durable answer (resolve the spelling from /v1beta/models, which the tree already queries) is deferred to its own cycle rather than ridden in. Three further work-phases shrank once the tree was read rather than assumed: WP2 drops to one file, because lidge-jun#1881 already landed two of lidge-jun#1899's three and lidge-jun#1899 is CONFLICTING as a result; WP3 drops to a single -ErrorAction Stop, because the sentinel and unknown state it proposed already exist; WP4 keeps its key-completeness finding, which is real, but gains the constraint that the sibling cache's identities are process-local HMACs, so copying them into a durable key would silently break restart replay instead of fixing scope. Merge orders are corrected too: 5D leads with lidge-jun#1891 rather than the only red-CI PR, 5C names live-transport.ts as a four-way conflict surface with a rebase step per merge, and merge order is verified with rev-list --topo-order rather than --is-ancestor, which cannot observe order at all.

Superseded on Two were overtaken by #1881. One carried something #1881 did not have, and it is the reason this was worth One thing was added on top. This PR asserts set membership — Driven red both ways before landing (4 of 9 fail when the order is violated), and Thanks for this — the binding idea is yours, and the ordering guarantee only became |
The catalog writer tests asserted that a temp file was written, that something was hardened, and that something was published - three unbound some() checks that all hold even when the three touch different files, which is the failure they exist to catch. On Windows that is the only proof available: chmodSync moves the read-only flag alone and statSync keeps reporting 0o666, so real restriction comes from the per-user NTFS ACL rather than a mode. Order matters as much as membership. Hardening lands on the temp file and publishing moves that already-restricted file into place; a writer that published first and hardened after would leave the destination world-readable for the width of the gap, and a set-membership assertion passes for that writer too. Comparing the recorded indices is what turns this into a claim about the race instead of a claim about the call list. Driven red before landing: forcing the harden index above the publish index fails 4 of the 9 tests, and restoring returns all 9 to green. lidge-jun#1899 reached the same binding for this file; its other two files are already covered by lidge-jun#1881, which is why that branch now conflicts. This is the surviving residue, rewritten with the ordering guarantee that neither lidge-jun#1881 nor lidge-jun#1899 actually asserted.
The reviewer's ablation turned up something the plan did not predict. For the two backup mutators the index comparison is the only detector there is: publishNoReplace is linkSync, so a temp hardened after publication still shares the destination's inode - chmod succeeds, statSync reads 0o600, the leftover check passes, and every other assertion agrees nothing is wrong. Only the order disagrees. That is a stronger argument for the assertion than the one the plan made for it. Also records the scope limit now written into the test, and re-verifies lidge-jun#1899 as CONFLICTING after it briefly read UNKNOWN while GitHub recomputed.

Part of the #1059 Windows burn-down.
What is failing
Six tests across the Codex write substrate assert that a published file ends up at mode
0600:On Windows that assertion can never pass.
chmodSyncthere moves the read-only flag and nothing else, sostatSyncreports0o666no matter how the file was written:Two of the six fail on their own setup line —
codex-transition-stateandnative-main-claimbothchmoda file to0o644and assert that first — so they never reach the behaviour they exist to check.Why this is the test, not the product
The restriction is real; on Windows it is an ACL rather than a mode. Each call site touched here reaches it:
codex-catalog-writerdefaultBackupWriteIO/atomicWriteFilehardenSecretPathnative-main-claimopenClaimDatabasehardenSecretPathAsyncdsh-writer-lockatomicWriteFilehardenSecretPathsrc/integrations/journal.tsstates it outright: writes "go throughatomicWriteFile, which applies 0600 plus Windows ACL hardening."So the mode assertion is scoped to the platform whose semantics it is expressed in, and the ACL half stays where it can actually be observed —
tests/windows-secret-acl.test.ts.The catalog-writer cases needed more than a scope guard
For those four, the mode was the only evidence that the writer restricted anything, so skipping it on Windows would have left them weaker there. They now assert the
harden:effect as well — the half of the contract that holds on every platform:That is a stricter check than the mode was. Deleting
io.hardenfrompublishCatalogBackupand fromatomicWriteFileturns all four red:The old mode assertion could not see that regression on Windows at all, since
0o666is what it reports either way. This is the failure mode thenative-main-claimheader already warns about: "an audit deleted the hardening call fromopenClaimDatabaseand 89 tests across three files stayed green."native-main-claimis skipped rather than scoped because its own comment already draws the line — "On POSIX that is the mode; the Windows branch is proven separately" — and every line of it, setup included, is written in mode terms.One neighbouring failure deliberately left red
codex-transition-state's "a coordinator found group-readable is narrowed back to owner-only" fails identically, and I did not touch it.src/codex/transition-state.tsdoes not importwindows-secret-aclat all. Neither doescatalog-write-serialization.tsorhistory-lock.ts, and all three carry the same comment on a barechmodSync:If that work is still outstanding, those coordinator databases are genuinely not narrowed on Windows, and the red test is honest signal rather than a platform artifact. Scoping it away would have hidden that. Happy to send the follow-up if you confirm which way it should go — the two shapes are "apply the ACL" and "record the gap".
Verification
Windows 11, Bun 1.3.14, against
dev:The three still red after this change are the
codex-transition-statecase described above, plus two unrelated failures in that file (busy and unavailable databases return typed outcomes instead of throwing, and arow validatorcase that times out at 5s) which are not mode-related and are out of scope here.No production file is modified; the
