# HyperTwist Phase 4 template launch confidence snapshot provenance packet

## Purpose

This packet persists the comparable-peer confidence-lane state that the dashboard already shows before launch for broader `TemplateScopedOutcomeSignal` analytics winners. That state is now stamped into template selection provenance at selection time and read back through template history and run recap, so later audits preserve the dashboard's at-launch view instead of recomputing it from drifted current template stats.

## Scope

- add a compact comparable-peer confidence snapshot payload under template launch selection provenance
- stamp that snapshot when the dashboard builds a broader analytics tie-break selection provenance
- make the live template-launch status clause prefer the stored snapshot and only fall back to current stats for compatibility
- append stored at-launch confidence snapshot detail to the shared template selection detail path used by live detail, template launch history, and run recap

## What landed

- `HyperTwistTrainingTypes.h`
  - added `EHyperTwistTrainingTemplateLaunchComparablePeerConfidenceSnapshotState`
  - added `FHyperTwistTrainingTemplateLaunchComparablePeerConfidenceSnapshot`
  - nested the new snapshot under `FHyperTwistTrainingTemplateLaunchSelectionProvenance`
- `HyperTwistCoachDashboardWidget.cpp`
  - added a helper that captures comparable-peer outcome count/share and peer-no-evidence count into a selection snapshot
  - broader `TemplateScopedOutcomeSignal` tie-break provenance now stores that snapshot at selection time
  - the live `[Template Launch]` status clause now prefers the stored snapshot from selection provenance
  - shared template selection detail now appends a concise `at-launch confidence lane` fragment sourced from persisted selection provenance

## Product effect

- the live dashboard still shows the same confidence-lane posture for broader analytics winners
- template launch history now reflects the at-launch confidence-lane snapshot even if the template's current scoped analytics later drift
- run recap inherits the same persisted at-launch confidence fragment through the existing template selection detail path

## Acceptance criteria

- broader analytics tie-break selection provenance persists comparable-peer confidence snapshot state
- live status clause uses stored snapshot when it exists
- template launch history selection detail shows stored at-launch confidence snapshot without recomputing from current stats
- run recap selection detail shows the same stored at-launch confidence snapshot

## Validation checklist

1. full `Development Editor|Win64` build succeeds
2. confirm broader analytics tie-break provenance stamps the new snapshot
3. confirm live status clause still distinguishes `confidence-eligible`, `suppressed`, and `no retained lane yet`
4. confirm template history and run recap selection detail append the stored `at-launch confidence lane` fragment
