# HyperTwist Phase J-EZ validation predella-state ledgers and bounded ongoing-state dossal implementation packet

Date: 2026-06-01

`Phase J-EZ` is now landed locally as the one-hundred-fifty-sixth bounded
validation seam in the first-party HyperTwist runtime-evidence ladder.

## Landed surfaces

- validation predella-state ledger contract
- validation ongoing-state dossal boundary
- bundled runtime accessors for both surfaces
- focused automation coverage for the new contract and boundary

## Implementation notes

- the `predella-state` / `ongoing-state dossal` 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
  pattern because current canon names `Phase J-EZ` but does not yet spell out
  its noun pair
- added predella-state ledger contract data, ids, lookup seams, and bundled runtime
  accessors
- added ongoing-state dossal boundary data, ids, lookup seams, and bundled
  runtime accessors
- extended the validation benchmark reference bundle and structural-validity
  contract with the new bounded seam
- kept package ownership first-party and runtime-evidence scoped

## Guardrails preserved

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

## Ladder status

- `Phase J-A` through `Phase J-EZ` are now landed as the first bounded
  validation and benchmarking ladder
- the current deliberate next seam is:
- `Phase J-FD`
