fix(antigravity): send a bare ide_version + Wave 5 closeout record - #1957
Merged
Conversation
A reviewer noted that a reader skimming only the top of this file takes away the pre-reorder chain and the close-#1836-as-superseded line, both of which execution overturned. The original text stays - it is the record of a decision changing - but the reader now meets the correction before the thing corrected.
Full suite green on the promotion candidate: 12805 pass, 10 skip, 0 fail across 826 files, plus typecheck and privacy scan clean. Three issues closed under the close-on-dev-merge decision - #1894, #1843, #1899. Everything else stayed open, and none of it for release-timing reasons, which is the honest verdict on that policy change: it removed a gate that was never what held these back. Also recording what the promotion does not have. Dev's hosted CI has no completed green run on its current head, because the runs at 2b12521 and aca3c02 were both cancelled by supersession as later merges landed. The local full suite is the evidence that exists; a hosted run on the exact promotion head is the evidence that does not.
Three PRs landed and four are held, each for a reason that belongs to the PR rather than to my schedule. The part worth keeping is the defect I introduced. #1951 fixed #1895's blocker by deciding code mode from freeform metadata rather than the name exec, but my port of the shell-bridge predicate dropped the Cursor original's !tool.namespace requirement - so a namespaced MCP exec_command cancelled code mode on a genuine code-mode turn and silently stripped the guidance. It failed safe, generic rather than false guidance, which is precisely why nothing caught it and why an audit that runs the predicate against adversarial catalogs beats one that reads it. #1953 fixes it, driven red first, and a second reviewer then failed to break the classifier across ten catalog shapes.
Wave 5D was smaller than planned. #1897 had already merged as aca3c02 and #1836 was already closed, so half the wave was resolved before the phase ran. #1891 I verified rather than took on trust: clean merge onto dev, 75 pass / 0 fail across the three fingerprint suites, typecheck clean. Its description carries a decompiled token sequence and a live round trip, which is the right evidence for a fingerprint change because the failure mode is silent upstream rejection rather than a failing test. It is held only by its own unticked readiness checklist. #1889 is the campaign's second auth-surface block after #1888. It touches src/oauth/, MAINTAINERS.md requires explicit security review there, and the maintainer-sponsored label is the record that the review happened - so applying it to unblock a merge would make the record false rather than skip a step.
Onboarding was filling metadata.ide_version with antigravityUserAgent(), which returns the entire header - antigravity/ide/2.5.5 (aidev_client; os_type=...; arch=...) - where the real client sends 2.5.5. Nothing failed, and that is the point. The request still succeeds; it just does not look like Antigravity. A fingerprint is only worth having if it matches, and this one had a parenthesized UA string sitting in a version field on every onboarding call. ANTIGRAVITY_IDE_VERSION already existed one import away. The regression pins the field and asserts the shape it must not have, so the next person reaching for the UA helper here gets a failure instead of a silently wrong fingerprint. Driven red: restoring antigravityUserAgent() fails the new test.
…ompted Two record errors. #1889 has two distinct failing checks, not four - four was the count of failing check runs across re-runs. And the audit's finding that #1891 sits 62 commits behind dev is itself stale: the live head 8123680 is 0 behind, so ticking alone is now sufficient. Keeping that as a lesson rather than deleting it, because the mechanism it named is real and would have made my advice wrong on a different day. The audit also asked whether anything here could be landed rather than held, and one thing could: metadata.ide_version was set to antigravityUserAgent(), the whole header, where the real client sends a bare version. Live on dev, independent of both PRs, and invisible because the request still succeeds. Fixed in #1955. That distinction is worth stating. I hold #1889 because reviewing someone else's auth change is the maintainer act the sponsorship label records - but a one-line auth fix I wrote and verified myself is precisely the case where a maintainer sponsors their own work.
Two corrections from the promotion audit. The closed table listed #1894, #1843 and #1899 as issues. #1899 is a pull request, so two issues closed this campaign, not three - the original phrasing overstated the run. And PR #1921's merge commit carries a failing hosted run. The failure is a wall-clock assertion in request-pacing, the classic flake shape on a loaded macOS runner, and every subsequent run on dev is green including the current head. Not a blocker, but it landed red and the record did not say so. A campaign record that omits the one merge that went in red is not one you can trust later. Also supersedes the no-green-run statement: run 32090176020 on 9eb3a10 is completed/success with every job green.

Keep one authoritative WP7 outcome.
Lines 52-63 already record a different WP7 status: #1895 and #1896 are held, #1887 is kept open, and #1903 needs a rebase. Lines 71-82 add a second ## WP7 outcome with conflicting final statuses. Remove Lines 52-70, or label that block as superseded historical context, so the file has one authoritative outcome for audit and merge decisions.

I held lidge-jun#1891 and argued lidge-jun#1889 must land first. lidge-jun#1891 merged without it at 02:25:46Z; lidge-jun#1889 is still open and draft. For a while this document and both promotion PR descriptions described lidge-jun#1891 as deliberately excluded while it sat on the promotion head - which is the worst kind of error in a record written to inform an approval, because a maintainer would have approved believing the promotion excluded a change it contained. The concern is addressed on that head anyway, by a different route than the hold pointed at: lidge-jun#1957 made ide_version a bare constant, so the body field no longer carries the User-Agent. The hold was right about the defect and wrong about which PR would fix it. Two smaller ones. Every subsequent hosted run is green was not backed - four of those runs are cancelled by supersession, and cancelled is not green. And the campaign landed ten functional PRs, not nine; the count predated lidge-jun#1891.

I credited it to lidge-jun#1957, whose merge touches two devlog files and zero code. Its title mentions the fix because it carried the record of it, three minutes after lidge-jun#1955 actually landed it. git log -S on the changed line returns exactly one commit and it is lidge-jun#1955's. This is the correction that mattered most: a maintainer verifying the claim would have opened lidge-jun#1957, found no code, and had good reason to distrust everything else in the document. Two more numbers fixed. Cancelled runs after 9dbc5fc are six or more, not four - this branch supersedes its own CI faster than it finishes. And the PR count is dropped rather than corrected a third time: I wrote nine, then ten, and neither was derived from anything.

Summary
Closes out the Wave 5 campaign: the final gate result, the corrected closure record, and one
production fix that came out of the audit.
The fix.
metadata.ide_versionon Antigravity onboarding was being filled withantigravityUserAgent()— the entire header,antigravity/ide/2.5.5 (aidev_client; os_type=…; arch=…)— where the real client sends2.5.5. Nothing failed, which is the point: the requestsucceeds, it just does not look like Antigravity. A fingerprint is only worth having if it
matches.
The gate. On the promotion candidate:
bun test --isolate testsat 12805 pass / 10 skip /0 fail across 826 files,
typecheckclean,privacy:scanpassed. Hosted CI is green on thecurrent
devhead (9eb3a101a, run32090176020) — all four shards, macOS, keyring andnpm-global on three OSes each.
Two record corrections, both from the audit and both against my own earlier claims:
issues closed this campaign, not three.
in
request-pacing, the classic flake shape on a loaded macOS runner, and every subsequentrun on
devis green. Not a blocker, but the record did not mention it, and a campaign recordthat omits the one merge that went in red is not one you can trust later.
