Why
The existing fixed-profile harness treats each 1,179-byte datagram as an encoded frame, so its reported frame rate, frame boundaries, bitrate, queue pressure, and processing evidence do not model the named 60/120 FPS profiles.
The v6 complete-frame fixture subsequently exposed a source-fidelity defect on ordinary Linux runners: it emitted every UDP shard in one tight loop, unlike pinned Apollo's bounded intra-frame rate and batch schedule. The affected v6 qualification evidence remains retained but is superseded for candidate-readiness purposes.
Private Linux run 125 then demonstrated a separate production-ingress defect after source pacing was corrected: 33 successful fixture writes missing from MediaIngress matched 33 measured kernel UDP drops while decrypt/FEC, queue, pacer, QUIC, and client counters remained downstream of the shortfall.
The consumed v8 Section 7 attempt at 55afea72 subsequently failed after accumulated host scheduling delays exposed the production pacer's discarded schedule debt beyond its 5 ms instantaneous catch-up allowance. The retained partial evidence remains failed and supersedes 55afea72 as a final executable candidate.
Private Linux run 127/job 481 at exact source 122080ab342d20585d9a45db0017337b9ece570a then failed TestQualificationLossAndSteppedThroughputBounds: the 25% capacity step reported the 11-second convergence sentinel and 5,207,475 bytes in the measured five-second window. The run produced no artifact and was not retried. Its retained log is /private/tmp/versevdi-gitea-run-127-job-481.log, SHA-256 2b368413d4b0e954c64ba6f6dcefb1e165166d773b6d8f84ee372bc2c92ff5f1; 122080ab is superseded as a final source candidate.
Private Linux run 128/job 482 was the single push-triggered attempt at exact source 22433e5c45c179e9d487b59e5d80f1dcf3b285ce. Linux make verify, the sustained gate, strict OpenSpec, deterministic artifact generation, upload, and the clean-checkout step passed. Artifact 28's binaries and SPDX matched the frozen hashes and source metadata. The retained log /private/tmp/versevdi-gitea-run-128-job-482.log has SHA-256 6f5852dce815ba87a55d61aae34cb2fce17a1a62c5ee50e18c0034259ad0a029. The workflow requested 30 retention days, but Gitea 1.27 floored the positive request delay and its API scheduled exactly 29 elapsed days. The run was not retried: it is passing Linux execution and artifact-byte evidence but retention-nonconforming, so it does not satisfy the private Linux artifact gate or authorize normative Section 7. The local 31-day request preserves the at-least-30-elapsed-day requirement; a separately authorized future run must prove expires_at - created_at >= 2,592,000 seconds.
What Changes
- Generate deterministic variable-size encoded frame units at the named frame rates and target bitrates, including bounded keyframes.
- Traverse native Apollo recovery, production queues, the production pacer, QUIC framing, and independent reassembly.
- Assert frame count/rate, bitrate, exact bytes and boundaries, clean loss attribution, latency, and resource bounds.
- Decouple native video socket draining from the single decrypt/FEC processor with a fixed provider-scoped receive pool and request the source-backed video receive-buffer size.
- Retain bounded valid per-flow pacing debt after a host stall and repay it at no more than 5% above nominal fair share.
- Measure capacity convergence and rolling caps from each raw public QUIC datagram's observed length and receive time while retaining completed logical-payload observations for integrity and traversal results.
- Keep short smoke tests separate and leave all prior normative artifacts unchanged.
Capabilities
New Capabilities
None.
Modified Capabilities
gateway-qualification: Fixed-profile evidence measures complete encoded frame units rather than one datagram per frame.
Impact
The qualification harness, its canonical specification, native Apollo video ingress in gateway/apollo_native.go, and the existing production fair pacer in gateway/telemetry.go. Downstream complete-frame queues, audio/control ingress, codec/FEC formats, QUIC, dependencies, and public interfaces remain unchanged. No codec operation or normative rerun is included. Requirements: P3C-002, P3C-008, P3C-029, P3C-030, P3C-033, VER-009, VER-010, OPS-015.
