# HyperTwist Phase 8A browser runtime-status native-capture implementation packet

Created on `2026-06-19`

## Status

- first-party HyperTwist packet
- bounded first-party `Phase 8A` continuation slice

## Purpose

This packet hardens the already-landed embedded browser shipping lane one layer
below the browser-side status surface.

The landed slice is:

- decode first-party `browser-runtime-status` envelopes into typed Unreal-owned
  structs instead of leaving them as generic JSON only
- retain the last valid browser runtime-status snapshot through
  `UHyperTwistBrowserBridgeObject` and `UHyperTwistBrowserWidget`
- preserve that typed runtime-status ownership across later unrelated envelope
  traffic until an explicit bridge reset clears it
- widen focused browser automation so the new native-side retention behavior is
  verified on the primary reverse-SSH Windows lane

It is not:

- a topology widening into the optional full-browser client branch
- a native `MagicTile` renderer-port packet
- a reopening of the already-landed embedded browser/CEF host decision

## Current authority basis

This implementation packet stands on:

- `docs/ops/HYPERTWIST_COMPREHENSIVE_RECONSTRUCTION_ROADMAP_2026-06-10.md`
- `docs/v6_5_deep_manual_pack/HyperTwist/ROADMAP.md`
- `docs/v6_5_deep_manual_pack/HyperTwist/FEATURE_REGISTRY.md`
- `docs/v6_5_deep_manual_pack/HyperTwist/ARCHITECTURE.md`
- `docs/arch/HYPERTWIST_PHASE8A_BROWSER_STATUS_SURFACE_HARDENING_IMPLEMENTATION_PACKET_2026-06-19.md`

## Landed scope

Current code now hardens the live embedded-browser lane through:

- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistBrowser/HyperTwistBrowserBridgeObject.h`
  typed first-party `FHyperTwistBrowserRuntimeStatusSnapshot` and
  `FHyperTwistBrowserRuntimeStatusEnvelope` ownership
- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistBrowser/HyperTwistBrowserBridgeObject.cpp`
  typed decode and retained caching for `browser-runtime-status` envelopes
- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistBrowser/HyperTwistBrowserWidget.h`
  and
  `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistBrowser/HyperTwistBrowserWidget.cpp`
  widget-level forwarding for the retained runtime-status envelope
- focused browser automation in
  `UnrealHyperTwist/Source/UnrealHyperTwist/Tests/HyperTwistBrowserBridgeObjectTest.cpp`
  for:
  - typed runtime-status envelope decode
  - retention across unrelated later envelope traffic
  - explicit cache clearing on bridge reset

## Why this hardening mattered

The browser shell could already surface runtime-health facts inside the
embedded UI, but Unreal still only saw that packet as raw JSON even after the
status surface landed.

That left the authoritative native host without a typed ownership seam for the
same runtime facts the browser was projecting. This packet closes that gap
without widening product topology.

## Validation

Local validation:

- `git diff --check`
- result on `2026-06-19`: passed

Windows build validation:

- `Build.bat UnrealHyperTwistEditor Win64 Development -Project='C:\HyperTwist_worktrees\phase10validate\UnrealHyperTwist\UnrealHyperTwist.uproject' -WaitMutex -NoHotReloadFromIDE -NoUba`
- result on `2026-06-19`: `Result: Succeeded` with UnrealBuildTool
  `Total execution time: 111.69 seconds` on isolated worktree
  `C:\HyperTwist_worktrees\phase10validate`

Focused browser validation:

- `Automation RunTests HyperTwist.Browser`
- result on `2026-06-19`: found `8` `HyperTwist.Browser.*` tests and passed
  all `8`, exporting the report to
  `Saved\AutomationReports\Browser-RuntimeStatusNativeCapture-Verify`,
  including the hardened:
  - `Bridge.RuntimeStatusEnvelopeDecode`

## Product effect

This packet keeps the live embedded browser/CEF shipping lane intact, but it
upgrades native ownership quality:

- Unreal now retains a typed browser runtime-status snapshot instead of generic
  JSON only
- browser-side runtime-health facts now survive later unrelated bridge traffic
  until explicit reset
- the embedded browser lane becomes easier to reason about from Unreal-side
  code and future diagnostics without widening into a browser-first topology

Follow-on continuation:

- `docs/arch/HYPERTWIST_PHASE8A_BROWSER_RUNTIME_READY_NATIVE_CAPTURE_IMPLEMENTATION_PACKET_2026-06-19.md`
  now records the adjacent typed native capture seam for the original
  `hypertwist-runtime-ready` handshake payload, so the ready-authority handoff
  is no longer raw JSON only either.
