# v1.96 Milestone Audit

Status: passed

## Scope Closed

- Phase `170`: Three-Mode Positive Promotion Proof Lane
- Phase `170.1`: Negative-Result Promotion Proof Lane
- Phase `170.2`: E2E Evidence And Regression Closure

## Requirements Coverage

Score: `2/4` requirements satisfied as originally written, `2/4` explicitly
deferred after honest scope adjustment

- `REQ-E2E-01` was **not** satisfied as originally written. The milestone
  proved three fresh public-front-door topics can bootstrap cleanly across
  `formal_derivation`, `toy_model`, and `first_principles`, but all three
  positive lanes stopped at `L3` and never landed an authoritative positive
  unit in canonical `L2`.
- `REQ-E2E-02` was **not** satisfied as originally written because no positive
  promotion receipt existed to compare across `status`, runtime protocol,
  dashboard, replay, and promotion-gate surfaces.
- `REQ-E2E-03` was satisfied by Phase `170.1` through the HS-model negative
  result staging and `contradiction_watch` compilation proof.
- `REQ-E2E-04` was satisfied by Phase `170.2` through durable receipts,
  RUNBOOK-E replay guidance, and the cross-lane postmortem.

## Verification Evidence

- Phase `170` positive front-door bootstrap proof:
  - three fresh runtime topics materialized with `27/27` conformance:
    - `von-neumann-algebra-factor-type-classification-proof`
    - `haldane-shastry-model-quantum-chaos-and-lyapunov-spectrum`
    - `librpa-qsgw-convergence-verification-for-h2o-tight-basis`
- Phase `170.1` negative-result proof:
  - HS-model OTOC failure recorded via scratchpad
  - `stage-negative-result` wrote a durable staging entry
  - `compile-l2-knowledge-report` compiled that entry as `contradiction_watch`
- Phase `170.2` regression and replay closure:
  - durable receipts exist for lanes A/B/C/D
  - `RUNBOOK-E.md` provides mechanical replay instructions for all four lanes
  - `postmortem.md` records the exact non-proven positive-L2 gaps

## Cross-Phase Integration

- Phase `170` proved that the public front door and conformance audit are
  genuinely mode-agnostic across the three currently relevant research modes.
- Phase `170.1` proved that the repaired `negative_result` pipeline from
  `v1.95` can carry a real physics failure into durable `L2`-visible state.
- Phase `170.2` turned the three bootstrap receipts and the one negative-result
  receipt into mechanical replay artifacts instead of chat-only conclusions.

## Audit Notes

- This milestone was closed with an honest scope adjustment rather than by
  pretending the positive lanes reached `L2`.
- The positive front-door proof is still valuable because it demonstrates
  mode-correct bootstrap, mode-agnostic conformance, and durable receipt
  capture across all three target research modes.
- The next milestone must absorb the deferred positive-L2 proof rather than
  re-litigating whether `v1.96` already achieved it.

## Accepted Open Gaps

- `REQ-E2E-01`: one positive fresh-topic route must still travel all the way
  to canonical `L2`
- `REQ-E2E-02`: positive promotion receipt parity across runtime/read-path
  surfaces remains unproven until a real positive promotion lands
- `first_principles -> code_method` mapping remains untested on a real
  codebase-backed route
- toy-model convergence / benchmark acceptance remains untested beyond
  bootstrap
