# HyperTwist Phase 3 end-state freeze packet

Created on `2026-05-06`

Status:

- first-party HyperTwist packet
- bounded closure / execution-discipline slice

## Purpose

This packet defines the explicit late-Phase-3 closure framing after the generated-mode executor, linked-state rebuild closure, live schedule-policy feedback loop, same-pass coach derived-state resync, and thin generated-mode runtime consumer packet all landed.

The open task is:

- freeze the concrete Phase `3` end-state so future continuation does not reopen already-closed backend work by mistake

It is not:

- another generated-mode backend packet
- a broad orchestration expansion
- a recognition productionization packet
- a cleanup-only refactor

## Scope

Bounded lane:

- record the concrete owned Phase `3` end-state and its exit gate

Required result:

- one product-side packet document states which late-Phase-`3` slices are now closure-complete
- the packet states which thin runtime consumers already landed above the stabilized backend
- the packet states what is intentionally deferred so later sessions stop treating deferred work as missing closure work

Out of scope:

- new generated-mode materialization work
- new dashboard UX work
- additional runtime consumers beyond the already-landed thin packet
- changes to external plugin copies

## Current owned product truth

These pieces are now live in first-party code:

- owned training/coaching repository state with save/load/repair/integrity verification
- imported catalog overlay and bounded finite/non-finite imported runtime materialization
- active imported runtime selector state and generated-mode selector-choice persistence
- owned generated-mode launch-request creation, persistence, latest-request query, and bounded clean-room execution
- real dashboard routing through the generated-mode executor
- linked-state integrity and rebuild verification across learner, review, coach, queue, and queue-history surfaces
- live schedule-friction feedback folded back into coach brief shaping
- same-pass resynchronization of coach brief, follow-up brief, queue summary, queue state, and schedule-policy / queue-execution summaries
- thin runtime-consumer parity for the bounded generated-mode lane through:
  - `UHyperTwistTrainingPanelWidget`
  - `AHyperTwistTrainingSessionActor`

What this means in practical terms:

- HyperTwist can run owned practice, recommendation, follow-up, scheduling, and bounded imported generated-mode execution flows with durable repository state and coherent rebuild integrity
- the current open work is no longer a missing Phase `3` backend capability

## Phase 3 exit gate

For current roadmap discipline, Phase `3` should now be treated as closure-complete when judged against these criteria:

1. owned practice sessions run end-to-end inside first-party training/coaching code
2. repository state persists, reloads, repairs, and re-derives coach-linked state coherently
3. bounded imported generated-mode selection, request creation, persistence, latest-request inspection, and owned execution all work through first-party surfaces
4. at least the currently chosen thin runtime consumers above that backend exist and compile cleanly
5. no still-open task in this lane is secretly a missing backend dependency for ordinary Phase `3` continuation

Current read:

- those criteria are satisfied in live product code

## Do not reopen

Future continuation should not reopen these areas as if they were still the primary missing gap:

- generated-mode executor existence
- latest generated launch-request persistence or query support
- schedule-friction fold-back into coach shaping
- linked-state rebuild integrity across queue / queue-history surfaces
- same-pass coach derived-state resynchronization after late brief refinements
- thin generated-mode runtime-consumer parity in panel widget and session actor

## Intentionally deferred

These remain valid future work, but they are not required to keep claiming clean Phase `3` closure:

- broader generated-mode widening outside the bounded imported lane
- additional runtime consumers unless explicitly chosen as a new bounded packet
- recognition productionization
- exact classic-cubing state / transform engine completion
- deeper simulation / hyper runtime work
- broad file decomposition or cleanup-only refactor

## Next logical lanes after this freeze

After this packet, continuation should treat the next work as a deliberate new lane rather than unfinished hidden Phase `3` backend work.

Strongest next choices are:

1. a deliberately chosen additional thin orchestration / runtime consumer packet if product flow still needs it
2. the first real Phase `4` orchestration and recognition-productionization packet
3. later platform-deepening work only when explicitly chosen

## Suggested file ownership

Primary edit surface:

- `docs/arch/HYPERTWIST_PHASE3_END_STATE_FREEZE_PACKET_2026-05-06.md`

## Acceptance criteria

- the packet states the concrete current Phase `3` exit gate
- the packet records the landed late-Phase-`3` closure slices
- the packet distinguishes closed backend work from intentionally deferred future work
- the packet gives future sessions a clear do-not-reopen boundary

## Validation checklist

1. read the packet against the current product reality
2. confirm it matches the current restart/roadmap docs rather than the older executor-gap framing
3. confirm it does not claim later-phase work as already done

That is the packet.
