# Dark Core Immediate Reality Execution and Irremovable Temporal Witness Gate · Human Engineering Language (English)

> This is an English reading projection of validated native TCS/HLDP source. It is not a new canonical source and grants no execution authority.

## What this is

This is a **protocol** declaration with identifier `TCS-DARK-CORE-IMMUTABLE-REALITY-EXECUTION-GATE-20260909` and version `0.1.0`. The projector validates it with the Stage-1 compiler before changing its reading order.

## Who is here

The native source does not provide this field; the projector does not guess.

## Why this started

- **source**  `source`
  - **source identifier**：BINGSHUO-DIRECT-DK001-PHYSICAL-GATE-20260909  `source.source_id`
  - **source role**：DIRECT_HUMAN  `source.source_role`
  - **source checksum**：BIND_AT_COMPILE_TIME  `source.source_sha256`
  - **source address**：source://codex-current-dialogue/2026-09-09/dark-core-physical-gate  `source.source_uri`

## What changed

The native source does not provide this field; the projector does not guess.

## How it will execute

This is a non-executable declaration and has no action graph.

## Where to continue next time
