Review Change Stack

Walkthrough

The change adds dto.UnixTime for numeric timestamp JSON handling and migrates OpenAI-compatible DTOs, relay adapters, task conversions, stream state, and tests to preserve typed timestamps, including fractional values and optional task timestamps.

Changes

Unix timestamp handling

Layer / File(s) Summary
Timestamp type and DTO contracts
relaykit/dto/unix_time.go, relaykit/dto/openai_*.go, relay/channel/*/dto.go
Adds UnixTime JSON handling and updates response timestamp fields to use typed Unix timestamps.
Conversion and stream state propagation
relaykit/relayconvert/..., relay/channel/openai/..., relay/helper/common.go
Preserves upstream timestamps through response conversion and stream state without integer coercion or generated fallback timestamps.
Provider response and task adapters
relay/channel/*, relay/channel/task/*, model/task.go
Wraps generated timestamps with UnixTimeRaw and conditionally emits task update and completion timestamps.
Timestamp preservation tests
relaykit/relayconvert/**/*_test.go
Updates typed timestamp fixtures and verifies fractional timestamp preservation and stream timestamp precedence.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 945a7

The PR changes Responses stream timestamp handling, but the final usage event can lose the upstream fractional timestamp and missing metadata can produce a zero timestamp. These correctness issues can affect client-visible response timestamps, so the PR is not merge-ready until the propagation and fallback behavior are corrected.

Poem

I’m a rabbit with timestamps neat,
Typed numbers hopping down the stream.
Fractions stay and zeros hide,
Usage follows on the tide.
DTO carrots line the way—
Clean time fields save the day.

🚥 Pre-merge checks | ✅ 2 | ❌ 3

❌ Failed checks (3 warnings)

Check name Status Explanation Resolution
Linked Issues check ⚠️ Warning The PR accepts float timestamps, but UnixTime preserves fractional JSON instead of serializing created_at as an integer required by issue #6822. Normalize numeric timestamps to integer JSON during marshaling while retaining float-tolerant unmarshaling, then verify snapshot forwarding and usage extraction.
Out of Scope Changes check ⚠️ Warning The PR includes broad timestamp migrations across unrelated provider and video-task adapters beyond the Responses snapshot parsing objective. Limit the changes to Responses DTO parsing, Responses streaming, and the related chat-to-Responses and Responses-to-chat conversion paths.
Docstring Coverage ⚠️ Warning Docstring coverage is 7.58% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff.

Run the relaykit-only build before merge.

The timestamp assignments use dto.UnixTimeRaw correctly. Verify the complete relaykit module independently:

As per coding guidelines, changes affecting relaykit must be verified with cd relaykit && GOWORK=off go build ./...; a root-module build is insufficient.

Verify the standalone relaykit build before merge.

This also covers the related timestamp assignment sites in relaykit/relayconvert/response_registry.go.

🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Reuse the upstream timestamp for the final usage event.

When the Responses stream provides created_at, the converter retains that timestamp in its stream state. This call generates a new timestamp with time.Now() instead. The final usage chunk can therefore differ from every other chunk and can lose a fractional value such as 1786588600.0.

Expose or read the timestamp retained by ResponseStreamState and pass it to GenerateFinalUsageResponse.

As per PR objective, timestamp values must propagate through the Responses-to-chat streaming path instead of being regenerated at finalization.

Preserve a non-zero timestamp when created is absent. handleLastResponse unconditionally assigns lastStreamResponse.Created, which overwrites any fallback. Initialize createAt with dto.UnixTimeRaw(common.GetTimestamp()) and replace it only when dto.UnixTimeEmpty(lastStreamResponse.Created) is false. Empty values serialize as 0, not null.
