# HyperTwist Phase 4 template launch peer support-kind audit packet

Created on `2026-05-07`

Status:

- first-party HyperTwist packet
- bounded Phase `4` dashboard selector rationale slice

## Purpose

This packet extends the persisted analytics tie-break rationale so it explains the losing peer's support-kind guard posture alongside the winner's `SelectorSplitConfidence` justification.

The open gap was:

- the previous packet explained why the winning template's split-confidence bucket was trusted
- but tie-break audit still could not tell whether the losing peer lacked comparable support-kind evidence or had support-kind outcomes that failed the same guard

## Scope

Bounded lane:

- add a support-kind audit clause formatter aligned with the existing selector-split confidence guard
- classify a template's support-kind posture as:
  - lacking comparable guard evidence
  - failing to beat its template-signal bucket strongly enough
  - only marginally beating that bucket without clearing the guard
  - clearing the guard
- use that formatter in the persisted `SelectorSplitConfidence` analytics tie-break summary for both chosen template and peer

Out of scope:

- changing support-kind bucket aggregation
- changing tie-break thresholds or scores
- widening selection provenance schema
- changing non-dashboard selector rationale

## What landed

Primary code changes:

- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistCoachDashboardWidget.cpp`
  - added `BuildTemplateLaunchAnalyticsSupportKindGuardAuditClause(...)`
  - kept the richer rationale on the existing persisted selection summary path
  - when `SelectorSplitConfidence` backs the winner, the summary now records:
    - why the chosen template cleared the support-kind guard
    - whether the peer lacked comparable evidence or failed the same guard on weaker or marginal support-kind outcomes

## Product effect

Template tie-break audit is now more specific:

- live `[Template Launch]` selector detail shows the winner's support-kind guard result plus the peer-side explanation
- template launch history inherits the same explanation from persisted provenance
- template-backed recap inherits the same explanation from persisted provenance

## Acceptance criteria

- `SelectorSplitConfidence` selector rationale includes both chosen-template and peer-side support-kind audit clauses
- peer-side clause distinguishes missing comparable evidence from weaker or marginal support-kind outcomes
- live launch detail, template history, and recap continue to inherit the richer rationale through existing provenance plumbing
- full product build succeeds

## Validation checklist

1. build `UnrealHyperTwist.sln` / `UnrealHyperTwistEditor`
2. confirm `SelectorSplitConfidence` rationale names the chosen template's guard result
3. confirm the same rationale says whether the peer lacked comparable evidence or failed on weaker or marginal support-kind outcomes
4. confirm live detail, history, and recap all inherit the richer rationale without schema changes

That is the packet.
