# HyperTwist Phase S6-B First-Party Usage And Operations Audit Skills Implementation Packet

Date: 2026-05-31
Status: landed

## Implemented Outputs

- `skill/audit-provider-usage`
- `skill/inspect-provider-topology`
- `skill/diagnose-route-service`

## Landed Product Shape

The `S6-B` layer is now live as a bounded first-party provider/ops audit family
above the landed provider-neutral speech/provider seams and the landed `S6-A`
provider-profile/routing skill layer. It reads normalized first-party
usage/cost state, quota/rate-limit posture, route/service-health posture, and
bounded operator-shell topology to produce provenance-visible provider-usage,
provider-topology, and route/service-diagnostic briefs.

## Registry / Control / Audit

- registry status counts now include the three new implemented skills
- provider/operations family count now includes:
  - `provider-routing-inspector`
  - `inspect-provider-profile`
  - `setup-byok-profile`
  - `diagnose-provider-routing`
  - `audit-provider-usage`
  - `inspect-provider-topology`
  - `diagnose-route-service`
- sample audit control overrides enable the three new skills for
  invocation-ledger coverage

## Contract State

New bounded state family:
- `FHyperTwistSkillProviderUsageOperationsAuditSkill`
- `FHyperTwistSkillProviderUsageOperationsAuditState`

Derived state guarantees:
- every live skill reads normalized first-party state
- every skill requires the landed `S6-A` provider-profile/routing substrate
- every skill requires usage/cost accounting state
- every skill requires route and service-health state
- normalized first-party accounting ownership remains preserved
- settlement execution widening remains out of scope
- provider-portal widening remains out of scope

## Validation

- `S1-A` registry/family/status expectations updated
- `S1-B` control-state expectations updated
- `S1-C` audit-ledger expectations updated
- `S1-D` eval-contract coverage updated
- focused `Phase S6-B` automation added for:
  - coverage
  - normalized-state acceptance gates
  - JSON round-trip

## Documentation Sync

Updated:
- `ROADMAP.md`
- `SKILLS.md`
- `FEATURE_REGISTRY.md`
- `HYPERTWIST_IMPLEMENTATION_PHASE_1_KICKOFF.md`
- `HYPERTWIST_SKILLIZATION_AND_COMMAND_SURFACE_DOCTRINE_2026-05-21.md`

Next clean move:
- `S7-A` domain-pack framework
