# R2-H LIFECYCLE SIDECAR

**Artifact class:** GOVERNANCE / DESIGN RECORD (per-family lifecycle sidecar)
**Research family:** `R2-H` — horizon-boundary experiment
**Family status:** **CLOSED / IMMUTABLE**
**Outcome:** **NULL**
**This sidecar:** records the lifecycle state of every R2-H artifact so the
repository can always distinguish frozen evidence from transient output and
from superseded documents. It grants **no** execution authorization, changes
**no** scientific state, and is **not** scientific evidence itself.

| field | value |
|---|---|
| family | R2-H |
| current protocol | `r2-h-v0.1.0-frozen` |
| manifest | `R2-H-MANIFEST-v0.1.0-frozen` |
| family status | **CLOSED / IMMUTABLE** |
| outcome | **NULL** (acceptable non-positive result) |
| design frozen | 2026-08-26 — protocol + manifest recorded `DESIGN FROZEN — EXECUTION NOT AUTHORIZED` |
| execution completed | yes — `R2_H_EXECUTION_MANIFEST.json`, `R2_H_REPORT.md`, `R2_H_INFERENCE.json` |
| execution outcome | **NULL** — global gate not rejected; consistent with R1-R null persisting |
| immutable | yes — R2-H may **not** be reopened, re-analysed, or amended |

## DESIGN FROZEN vs EXECUTION COMPLETED — MUST NOT BE CONFLATED

1. **DESIGN FROZEN** — the protocol `r2-h-v0.1.0-frozen` and the manifest
   `R2-H-MANIFEST-v0.1.0-frozen` were frozen before execution. At design time
   they carried the status `DESIGN FROZEN — EXECUTION NOT AUTHORIZED`.
2. **EXECUTION COMPLETED** — a controlled execution subsequently ran under the
   frozen protocol; the execution manifest, the inference file, and the report
   record the completed run and its **NULL** outcome.

`DESIGN FROZEN` is a pre-execution lifecycle state; `EXECUTION COMPLETED` is a
post-execution lifecycle state. `NULL` is the scientific outcome of the
completed execution — an acceptable, non-positive result, never a failure.

## AUTHORITATIVE STATEMENTS

- R2-H outcome = **NULL**
- R2-H is **CLOSED / IMMUTABLE**
- R2-H may not be reopened, re-analysed, reinterpreted, or amended
  (`RESEARCH_CHARTER.md` §3; `RESEARCH_RULES.md` rules 6 and 18)
