# v1.99 Milestone Audit

Status: passed

## Scope Closed

- Phase `173`: LibRPA QSGW Bounded Target And Trust Contract
- Phase `173.1`: LibRPA QSGW Positive Promotion To Authoritative L2
- Phase `173.2`: LibRPA QSGW Replay And Three-Lane Convergence Closure

## Requirements Coverage

Score: `5/5` requirements satisfied

- `REQ-QSGW-01` satisfied by Phase `173` through one fresh
  `first_principles` topic that was narrowed to the bounded positive target
  `candidate:librpa-qsgw-deterministic-reduction-consistency-core`.
- `REQ-QSGW-02` satisfied by Phase `173` through an explicit codebase/workflow
  trust contract that fixed the bounded target to the deterministic-reduction
  thread-consistency core and preserved known non-claims about broader
  convergence.
- `REQ-QSGW-03` satisfied by Phase `173.1` through one human-gated promotion
  that landed `claim:librpa-qsgw-deterministic-reduction-consistency-core` in
  authoritative canonical `L2` with durable backend and repo-local receipts.
- `REQ-QSGW-04` satisfied by Phase `173.1` through compiled knowledge-report
  parity plus `consult-l2` parity for the promoted bounded `LibRPA QSGW`
  authoritative claim.
- `REQ-QSGW-05` satisfied by Phase `173.2` through one replayable acceptance
  lane plus one explicit note that the three requested research directions now
  each have a bounded positive baseline.

## Verification Evidence

- Phase `173` bounded target contract:
  - `pytest-librpa-qsgw-target-contract.txt`: `1 passed`
  - `pytest-first-principles-routing.txt`: `2 passed`
  - `librpa-qsgw-target-contract-acceptance.json`: `status = success`
- Phase `173.1` authoritative positive landing:
  - `pytest-librpa-qsgw-positive-l2.txt`: `1 passed`
  - `librpa-qsgw-positive-l2-acceptance.json`: `status = success`
- Phase `173.2` replay closure:
  - `pytest-librpa-qsgw-positive-l2.txt`: `1 passed`
  - `replay-librpa-qsgw-positive-l2.json`: `status = success`

## Cross-Phase Integration

- Phase `173` chose the only currently honest bounded `LibRPA QSGW` positive
  route supported by real code anchors and real validator evidence, instead of
  pretending full QSGW convergence was already proved.
- Phase `173.1` turned that bounded route into one authoritative canonical `L2`
  claim and proved backend writeback, repo-local mirror writeback, and
  consultation parity on an isolated work root.
- Phase `173.2` converted the bounded first-principles positive-L2 landing into
  a replayable package, then made explicit that all three user-requested
  research directions now have bounded positive baselines.

## Audit Notes

- This milestone follows the same audit convention as `v1.97` and `v1.98`: it
  was audited from phase `SUMMARY.md` files plus fresh replay receipts rather
  than from newly-created per-phase `VERIFICATION.md` files.
- No unsatisfied requirement remains in the `v1.99` traceability table.
- No new cross-phase blocker appeared in the bounded `LibRPA QSGW`
  authoritative-L2 replay.

## Accepted Open Gaps

- The bounded `LibRPA QSGW` lane is closed only for the deterministic-reduction
  thread-consistency core on the `H2O/really_tight iter=10` reference workflow.
- Broad real-topic natural-language dialogue tests across the three closed
  baselines remain the next unfinished frontier.
