The Signal Rail Workstation is a single self-contained HTML file — signal_rail_workstation_final.html — that provides a browser-based interface for reading, inspecting, staging, previewing, and writing back to a live Signal Rail instance. It requires no server, no build step, and no installation. Open it in a browser, grant it access to the folder that contains your Signal Rail instance, and it gives you a cleaner human surface for maintaining the canonical files directly.

​
What the workstation is for

Direct manual maintenance of Signal Rail files is possible, but it is easy to get wrong when routing, markers, authority, and promotion rules are all in play at once. The workstation exists to reduce that friction for the operator working outside an AI session. From the README, the workstation is for:
  • Reading canonical files — view the current content of each file in a structured, readable interface rather than a raw text editor
  • Inspecting runtime state — see the current working frame, folder path, and session metadata in the status area
  • Staging edits — prepare changes before writing them back
  • Previewing changes — review what will be written before it is committed to the .txt file
  • Writing back — save staged edits to the matching .txt files when local folder access is available
The workstation does not replace the canonicals and does not change their authority. It is a maintenance interface for a live instance, not an operating interface for an active AI-governed session.

​
How it works

The workstation is a fully standalone HTML file. It uses the browser’s File System Access API to read and write local .txt files in the Signal Rail instance folder when the user grants folder access through the browser’s native file picker. No data leaves the machine. No server is involved. The file operates entirely in the browser’s JavaScript environment using local file handles provided by the operator. To use it:
  1. Open signal_rail_workstation_final.html in a modern browser (Chrome, Edge, or any browser supporting the File System Access API).
  2. Use the folder access control to point the workstation at the folder containing your Signal Rail instance.
  3. The workstation reads the .txt files from that folder and populates the tabbed view.
  4. Make edits in the staging area, preview the result, and use the save action to write back.

​
UI structure

The workstation uses a dark theme throughout, built around a deep navy background (#0e131a) with a blue accent (#7dc6ff), mint highlights (#7fe2bd), and gold secondary accents (#f0c27b). The interface is organised as follows:
AreaWhat it shows
Topbar — BrandSignal Rail name and subtitle
Topbar — Status frameThree status cards: Project Host, Focus, Source; plus a Folder Path card showing the active instance path
Topbar — ActionsAction buttons: Open Folder, Import Snapshot, Export Snapshot, System Checks, Refresh
Tabs barFour primary view tabs — Read, Write, System, Dashboard — plus a fullscreen toggle
Utility rowGlobal search field; Current Focus input
Main surfaceThe active view’s content — file surfaces in Read, write form and preview panel in Write, runtime checks in System
The active tab is highlighted with a blue-tinted border and background (rgba(125,198,255, 0.17)). The Write view provides a structured form for preparing new entries — particularly useful for append-driven files, where the entries zone contract must be respected.

​
When to use the workstation vs direct text editing

Signal Rail files are plain text and can be maintained with any editor. Direct editing is a valid fallback. However, the workstation is the safer default for manual maintenance because:
  • It makes the append zone visible — the --- ENTRIES START --- and --- ENTRIES END --- markers are presented structurally, reducing the risk of writing outside the entries zone
  • It surfaces the entry zone contract — one start marker, one end marker, correct order, local template preserved
  • It keeps file routing decisions in front of the operator — the tab structure makes it harder to accidentally write to the wrong file
  • It provides a preview pass before any write is committed
Direct text editing remains appropriate when the workstation is not available, when the edit is trivial and the file’s contract is clear, or when the operator is confident in the target file’s structure.

​
What the workstation does not do

The workstation is a maintenance interface. It is not a replacement for the AI-governed session. Specifically, the workstation does not:
  • Activate the lateral kernel — 06_ai_to_ai.txt is not loaded or interpreted by the workstation; protocol behaviour is not enforced
  • Close the working frame — host project, working object, mode, scope, and authority are not automatically closed; the status cards show whatever was last set by the operator, not a live session state
  • Replace the entry sequence — the mandatory read order (00 → 06 → 01 → 03) must still happen in the AI session before substantive action
  • Enforce routing rules — the workstation does not stop the operator from writing to the wrong file; it is a human maintenance aid, not a governed agent
  • Handle authority disputes — if canonical files conflict, the workstation does not detect or resolve the conflict
Do not use the workstation as a substitute for the AI-governed session when routing, promotion, or authority decisions are involved. The workstation is for direct maintenance of a live instance — reading, staging, previewing, and writing back — not for operating the system’s governance logic.
The AI session must still be opened separately through 00_runtime_entry.txt and 06_ai_to_ai.txt. The workstation and the AI session serve different purposes and are used at different times.
