## 1. Red fixed-profile model

- [x] 1.1 Add deterministic frame-count, frame-rate, bitrate, keyframe, byte-total, and boundary regressions
- [x] 1.2 Prove the current 1,179-byte one-frame model fails the required profiles

## 2. Production-path qualification

- [x] 2.1 Replace packet payload generation with bounded variable-size complete frame units
- [x] 2.2 Carry frame-level source, recovery, queue, QUIC, delivery, and loss attribution through the existing path
- [x] 2.3 Assert frame rate/count, bitrate bounds, exact bytes/boundaries, processing latency, and resource bounds

## 3. Verification

- [x] 3.1 Run short production-path smoke tests for all three profiles and affected impairment accounting
- [x] 3.2 Validate the active OpenSpec change strictly

## 4. Frozen qualification

- [x] 4.1 Run the single normative Section 7 qualification after immutable Protocol consumer resolution

## 5. Pinned Apollo source-fidelity remediation

- [x] 5.1 Retain the v6 qualification attempt and mark its passing result superseded by the tight-loop source defect
- [x] 5.2 Implement v8 post-first-write, non-collapsing complete-frame UDP pacing with persistent cross-frame carry and verify the focused, race, short-resource, and cross-platform compile checks that passed
- [x] 5.3 Preserve private Linux runs 123 and 124 as failed evidence, the passing local v8 Darwin sustained run as non-Linux and non-normative, and the un-retried failed Darwin non-sustained pre-CI invocation with its exact throughput evidence
- [ ] 5.4 Run private Linux full verification and retain deterministic Linux artifacts for the frozen v8 harness descendant
- [ ] 5.5 Run one separately approved replacement v8 normative Section 7 qualification
