# HyperTwist PostHog Reference Incorporation Provenance Board - 2026-05-27

## Status

This document is the source-backed provenance and hierarchy note for the live
repo-backed reference-incorporation side currently materialized from
`PostHog/posthog`.

It closes the source-specific reference side that remained implicit after the
landed `Phase 4R-D` packet and the broader live-lane and mixed-license-boundary
audits.

It answers one narrow question:

- do the live `PostHog/posthog` reference targets reopen already landed
  first-party control-plane, replay-diagnostic, and rollout-governance
  implementation, or do they instead need a reference-side provenance-board and
  canon backfill

Result:

- no product-code reopening is required
- yes reference-side provenance-board and feature-canon backfill is required

## Counts confirmed from current first-party materialization

Current live `PostHog/posthog` reference-incorporation targets:

- `6` total rewritten reference targets
- all `6` are under `Control-Plane Telemetry and Replay Governance`
- all `6` stay inside the already-landed `Phase 4R-D` bounded lane

Exact surfaces:

1. `reference/posthog-replay-diagnostics-reference-page`
   - `SurfaceType`: `control-plane-replay-diagnostic-reference`
   - `IncorporationChannel`: `replay-diagnostic-contract`
   - `TargetAssetFamily`: `replay-diagnostic-note`
2. `reference/posthog-replay-segmentation-reference-page`
   - `SurfaceType`: `control-plane-replay-segmentation-reference`
   - `IncorporationChannel`: `replay-segmentation-contract`
   - `TargetAssetFamily`: `replay-segmentation-note`
3. `reference/posthog-feature-governance-reference-page`
   - `SurfaceType`: `control-plane-feature-governance-reference`
   - `IncorporationChannel`: `feature-governance-contract`
   - `TargetAssetFamily`: `feature-governance-note`
4. `reference/posthog-scheduled-change-reference-page`
   - `SurfaceType`: `control-plane-scheduled-change-reference`
   - `IncorporationChannel`: `scheduled-change-contract`
   - `TargetAssetFamily`: `scheduled-change-note`
5. `reference/posthog-early-access-reference-page`
   - `SurfaceType`: `control-plane-early-access-reference`
   - `IncorporationChannel`: `early-access-rollout-contract`
   - `TargetAssetFamily`: `early-access-note`
6. `reference/posthog-compliance-boundary-reference-page`
   - `SurfaceType`: `control-plane-compliance-boundary-reference`
   - `IncorporationChannel`: `compliance-boundary`
   - `TargetAssetFamily`: `compliance-boundary-note`

Important adjacent fact:

- all six targets preserve the explicit `MIT`-outside-`ee/` versus enterprise
  `ee/` exclusion boundary already enforced by the landed lane

## Slice-local verdict

| Slice | Primary authority | Secondary value kept | Result |
|---|---|---|---|
| First-party control-plane, replay-diagnostic, and rollout-governance implementation | first-party current code plus landed `Phase 4R-D` packet | retained `PostHog/posthog` reference targets stay subordinate provenance-grounding surfaces | unchanged live implementation owner |
| Rewritten replay-diagnostic, replay-segmentation, feature-governance, scheduled-change, and early-access grounding | `PostHog/posthog` retained boundary-sensitive lane | factual replay-triage, rollout, lifecycle, and governance semantics are preserved while prose remains first-party | unchanged retained reference-grounding surface beneath first-party contracts |
| Mixed-license and enterprise-subtree compliance boundary grounding | `PostHog/posthog` retained boundary-sensitive lane | the `MIT`-core versus `ee/` exclusion boundary stays explicit in a first-party compliance note | unchanged bounded compliance-grounding surface |

## Why no product-code reopening is required

The live surfaces here are already rewritten first-party targets, not copied
donor pages or donor product-shell UI.

The checked targets explicitly require:

- preserving factual replay-diagnostic, replay-segmentation, rollout,
  early-access, and compliance semantics
- rewriting donor wording, donor analytics-shell framing, and any broader
  product, cloud, account, or experimentation-platform assumptions

That means the retained surfaces are provenance and factual grounding, not
donor shell ownership.

So this pass does not reopen:

- the closed `Phase 4R-D` first-party control-plane lane
- any donor `ee/` subtree usage
- any broad PostHog product-shell adoption
- any mixed-license-boundary flattening

## Current exact grounded role

`PostHog/posthog` currently grounds six live rewritten first-party
contract/reference targets for `Control-Plane Telemetry and Replay Governance`:

- replay diagnostic signals and verdicts
- replay segmentation and warning categorization
- feature governance and blast-radius review
- scheduled-change and recurrence policy
- early-access lifecycle and enrollment flow
- `MIT`-core versus `ee/` compliance boundary

These targets preserve bounded control-plane and rollout-governance semantics
while keeping all surfaced prose and product framing first-party.

## Backfill result

### Earlier incorporation audit reopened

- `C:\HyperTwist\docs\HT_REPO_INCORPORATION_AUDIT_2026-05-11.md`

### Feature canon reopened

- `C:\HyperTwist\docs\v6_5_deep_manual_pack\HyperTwist\FEATURE_REGISTRY.md`

## Final call

The live `PostHog/posthog` reference-incorporation side is now explicit:

- `6` rewritten first-party contract/reference targets
- all `6` remain inside the landed `Phase 4R-D` control-plane lane
- the `MIT`-outside-`ee/` versus enterprise-`ee/` boundary stays explicit

This closes the `PostHog/posthog` reference side without reopening product
code.
