Use encoding/json instead of Go string quoting when promoting message content to cached text blocks. Add regression coverage for control characters, Unicode, literal backslashes, text preservation, and idempotence.
An OpenAI group that keeps a failover account for a shared public alias
produced a Codex model descriptor with no reasoning levels and text-only
input, which leaves the client's reasoning-effort slider with nothing to
select.
Two accounts explicitly mapping one alias to different upstream models
makes codexExplicitModelTargetsConflictForPlatform true. With no
upstream_model_metadata snapshot to intersect, groupCodexModelMetadata
short-circuits to {reasoningConflict, inputModalitiesConflict}, so
DefaultReasoningLevel is nil (the key vanishes under omitempty) and
SupportedReasoningLevels is an empty array. mergeMissingCodexModelFields
fills only missing-or-null fields, so an empty array is never repaired.
Failing closed is right when the alias target is genuinely ambiguous, but
a group that declares model_routing for the alias has already resolved
that ambiguity: the operator stated which accounts serve it and which is
primary. Treating that as a conflict rejects a deliberate failover setup.
Manifest side: when a routing rule names the alias, restrict capability
declaration to the routed accounts and skip the conflict override.
Capabilities then fall back to the same by-name derivation used for a
single account without a metadata snapshot. Groups with no rule, a
disabled rule, or a rule for another alias keep failing closed.
Scheduling side: model_routing was stored and read platform-agnostically
(admin_group.go, Group.GetRoutingAccountIDs) but four gates in
gateway_scheduling.go only consulted it for Anthropic, so an OpenAI
group's rules were accepted and displayed yet never honored. Without
this, the manifest would honor a rule that scheduling ignores. Both
gates now share one predicate, with the allowed platform set defined in
a single place.
Selection inside a routing list is unchanged: the list is a membership
set, and the winner is still decided by Priority, then load, then
LastUsedAt.
Tests: alias-failover manifest recovery plus the three negative cases,
the platform predicate table, and an OpenAI routed selection that must
beat a higher-priority unrouted account.
Upstream returns 400 INVALID_ARGUMENT when toolConfig is absent. The guard
`if !isReasoning || len(tools) > 0` skipped it for reasoning models called
without tools, contradicting the intent stated in the comment above it.
Set toolConfig unconditionally and cover the three cases with a unit test.
Payment and admin fulfillment shared the public Redeem entry point, so
fulfillment retries were blocked by, and contributed to, the user's
public redeem failure counter, and lookup errors were silently treated as
"code does not exist" on a partial re-run.
- resolveRedeemAction now distinguishes a genuine not-found lookup from
other lookup errors (which now fail the fulfillment instead of being
swallowed and re-created).
- Add validatePaymentRedeemCode: before reusing an existing code during
fulfillment, verify it belongs to the order (code id, balance type,
amount, user, status), so a stale or foreign code can never be
credited against the wrong order/user.
- Split Redeem into a policy-based core: public redemption enforces the
failure counter; payment fulfillment (redeemForPaymentFulfillment) and
admin fulfillment (RedeemForAdminFulfillment) bypass it, while all code
validation and transactional updates remain identical. Admin
fulfillment keeps the normal redeem-level affiliate rebate.
- The admin CreateAndRedeem endpoint now uses RedeemForAdminFulfillment.
Tests: updated resolveRedeemAction cases, new TestValidatePaymentRedeemCode,
code-used-by-another-user rejection, payment/admin rate-limit bypass
coverage, and public-path regression coverage.
The redeem failure counter used INCR followed by Expire(24h) on every
attempt, so each failed attempt refreshed the key TTL and the window
never actually closed for a user who kept retrying within 24h.
- Count attempts in a fixed 10-minute window via a small Lua script
(INCR, then PEXPIRE only when the key is created or has no TTL), which
is atomic and also repairs keys that lost their TTL.
- Move the counter to the redeem:ratelimit:v2: key space so pre-existing
24h counters do not seed the new window.
- Rename the service threshold to redeemMaxFailedAttempts (30) to reflect
that it bounds attempts per window, not per hour.
Public redeem behavior is unchanged apart from the window semantics:
the check fails open when the counter read fails, and a failed
increment never masks the underlying domain error.
The Antigravity native Gemini route (generateContent) expects each
contents entry to carry an explicit "user" role, matching the request
shape used by the established Antigravity account-test flow. Without it
the probe body is rejected with 400 INVALID_ARGUMENT, so Gemini channel
monitors report false failures.
Add the explicit role to the Gemini provider adapter body and cover it
with a regression test that parses the generated request body.
The Antigravity service fingerprints clients by the version embedded in the User-Agent header. The built-in default (1.23.2) had drifted far behind current real client builds, so requests using the default UA started failing OAuth and probe flows.
Bump DefaultUserAgentVersion from 1.23.2 to 2.9.1 (current client build) and update the constant test accordingly. The default remains overridable via ANTIGRAVITY_USER_AGENT_VERSION and the admin setting.
The Grok cross-client model mapping is enabled by default: InitializeDefaultSettings writes "true", and the parser treats a missing/empty value as enabled ("Default true (missing/empty -> enabled)"). However the comment above the defaults and the admin settings UI hint (EN and ZH) both claimed "disabled by default", contradicting the actual behavior.
Align the comment and both UI hints with the real default. No behavior change.
Claim scheduler-acquired slots before media eligibility checks and task-owner
validation. Release abandoned attempts immediately and retain once-only
cleanup on cancellation and forwarding completion.
Select only the resolved video owner, reuse bounded account waiting without
sticky escape, and preserve the task binding and TTL. Keep generation
failover and owner/billing isolation intact.
Regression tests reproduce unreleased account slots on upstream ab99d56e9
and pass with this change. Validation: go test ./..., unit and integration
suites, focused race tests, backend build, and golangci-lint (0 issues).
