# HyperTwist Phase J-FA validation frontal-state packets and bounded ongoing-state antependium preparation packet

Date: 2026-06-01

## Objective

Extend the bounded validation lane with first-party frontal-state-packet and
ongoing-state-antependium surfaces without widening HyperTwist into generic
frontal-state platforms, antependium systems, or release authority.

The `frontal-state` / `ongoing-state antependium` naming is an explicit local
continuation inference from the landed lectern/pulpit/ambo/minbar/cathedra/bema/sedilia/choir/stall/pew/nave/aisle/sanctuary/altar/retable/ciborium/predella
pattern because the current roadmap canon names `Phase J-FA` but does not yet
spell out its noun pair.

## Planned surfaces

- validation frontal-state packet contract
- validation ongoing-state antependium boundary
- bundled runtime accessors for both surfaces
- focused automation coverage for contract and boundary resolution

## Guardrails

- keep validation frontal-state and ongoing-state antependium posture first-party
  and runtime-evidence local
- do not widen into generic frontal-state platforms or ongoing antependium systems
- do not widen into cross-product ongoing antependium ownership or frontal
  orchestration
- do not turn the seam into release-gate authority or public leaderboard logic

## Intended package posture

- `package/hypertwist-validation-frontal-and-ongoing-antependium`
- frontal continuity remains bounded to replay-anchor, benchmark-drift,
  manual-waiver, and continuity-context evidence
- ongoing antependium remains bounded to same-lane runtime evidence and explicit
  exclusion framing

## Next seam after landing

- `Phase J-FD`
