# Roadmap: v1.98 Toy Model Positive L0 To L2 Closure

## Result

All milestone phases are complete. Milestone lifecycle is next.

## Phases

- [x] **Phase 172: HS Model Positive Target And Benchmark Contract** *(Axis 1 + Axis 2)*
- [x] **Phase 172.1: HS Model Positive Promotion To Authoritative L2** *(Axis 2 + Axis 4)*
- [x] **Phase 172.2: HS Positive Replay And HS Negative Coexistence Closure** *(Axis 4 + Axis 5)*

## Target Outcome

- one fresh public-front-door `toy_model` topic lands one bounded positive
  `HS model` unit in canonical `L2`
- one explicit benchmark or convergence contract proves the positive target is
  honest enough for promotion
- compiled L2 and `consult-l2` expose both the positive `HS model` landing and
  the existing HS negative-result route without authority drift
- the milestone closes with replay receipts and explicit carry-over routing for
  the deferred `LibRPA QSGW` lane

## Next Step

Run milestone lifecycle: audit, complete, and archive `v1.98`.

### Phase 172: HS Model Positive Target And Benchmark Contract

**Axis:** Axis 1 (layer capability) + Axis 2 (inter-layer connection)

**Goal:** choose one bounded positive `HS model` target and prove it has an
honest benchmark, convergence, or analytic-trust contract before any L2
promotion claim.

**Motivation:**

- the existing HS route in `v1.96` is negative and physically honest, but not
  a positive authoritative-L2 closure
- `v1.97` now provides the stronger L2 baseline needed to widen into the
  next mode
- the next bounded step must distinguish a real positive `HS model` target
  from the already-proven OTOC mismatch failure route

**Requirements:**

- `REQ-HS-01`
- `REQ-HS-02`

**Depends on:** `v1.97`
**Plans:** 1 plan

Plans:

- [x] `172-01` Choose one bounded positive HS-model target and close its
  benchmark or convergence contract

### Phase 172.1: HS Model Positive Promotion To Authoritative L2

**Axis:** Axis 2 (inter-layer connection) + Axis 4 (human evidence)

**Goal:** carry the benchmark-gated positive `HS model` target from the public
front door to one authoritative canonical `L2` unit.

**Motivation:**

- benchmark honesty without promotion still leaves the toy-model lane short of
  the user-requested authoritative-L2 closure
- the formal lane now proves the architecture can do this; the toy-model lane
  must now prove it in its own scientific regime

**Requirements:**

- `REQ-HS-03`
- `REQ-HS-04`

**Depends on:** Phase `172`
**Plans:** 1 plan

Plans:

- [x] `172.1-01` Promote one bounded positive HS-model unit into authoritative
  canonical `L2` and prove compiled/read-path parity

### Phase 172.2: HS Positive Replay And HS Negative Coexistence Closure

**Axis:** Axis 4 (human evidence) + Axis 5 (agent-facing roadmap clarity)

**Goal:** close the positive `HS model` proof with replay receipts and explicit
coexistence against the already-shipped HS negative-result route, while
routing the deferred `LibRPA QSGW` lane explicitly forward.

**Motivation:**

- the toy-model lane should close more strongly than bootstrap-only or
  chat-only claims
- the existing HS negative-result route is the natural honesty check for the
  positive widening work

**Requirements:**

- `REQ-HS-04`
- `REQ-HS-05`

**Depends on:** Phase `172.1`
**Plans:** 1 plan

Plans:

- [x] `172.2-01` Replay the positive HS-model proof, prove coexistence with the
  HS negative route, and route the deferred QSGW lane
