Three of the four things blocking a first public release. Screenshots are the fourth and need a human with a running editor — see below.

Changes

  • README.md rewritten. It's the marketplace page, and it described the pre-August extension: a "Targets" view that no longer exists under that name, and nothing about the Explorer dock, Run Configuration, or Run with Parameters. Now documents the shipped feature set, plus a Settings table and the --plan step needed to populate the views.
  • Deployment view gated behind fallout.deployment.enabled, default false. No released Fallout emits a deployment graph, so today a first-time installer gets a view that can never populate. The setting keeps it discoverable for anyone following the work.
  • galleryBanner added (#0d0d0f, dark) — matches the social preview rather than rendering on default white.

Verified

tsc clean, and vsce package produces a sane .vsix: readme, LICENSE, five compiled JS files, the icon, and Mermaid as the only node_modules entry. No src, no maps, no .assets.

Not in this PR

Screenshots. Screen capture isn't available to me here, and I'm not going to fabricate product shots for a marketplace listing. .assets/screenshots/README.md carries the shot list and the constraints that matter — capture from an Extension Development Host with this repo open (it builds with Fallout, so the graph is already populated), dark theme, and README links must be absolute raw.githubusercontent.com URLs pinned to develop, because vsce rewrites relative ones to a base that isn't guaranteed to match.

The README is the marketplace page, and it still described the extension as it
was before August: a single "Targets" view, no Explorer dock, no Run
Configuration, no Run with Parameters. It now documents what actually ships,
including that secrets go to the OS keychain and reach the build as environment
variables rather than arguments.

The Deployment view goes behind fallout.deployment.enabled, off by default. No
released framework version emits a deployment graph, so a first-time installer
would otherwise find a view that can never populate.

Adds a gallery banner in the social preview's colours, so the listing does not
render on default white.

📝 Summary

Summary by CodeRabbit

  • New Features

    • Added a setting to control whether the Deployment view is displayed; it is disabled by default.
    • Added a dark-themed marketplace gallery banner.
  • Documentation

    • Expanded feature documentation covering build views, run configurations, definitions, build graphs, settings, requirements, and versioning.
    • Added guidance for placing and capturing required marketplace and README screenshots, including sizing and display requirements.

Walkthrough

The extension manifest now defines and gates the Deployment view setting. The README documents extension features, run configuration, graph behavior, requirements, settings, and versioning. New guidance defines screenshot asset placement and capture requirements.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to a5eb4

The README documents secret passing safely in several respects, but its guarantee that secrets cannot reach logs may cause users to rely on protection that build tools cannot ensure. Narrow the claim before release.

A form for the parameters and secrets your build takes:

- **Parameters** are passed as `--name value` arguments and stored per workspace.
- **Secrets** are stored in VS Code's [SecretStorage](https://code.visualstudio.com/api/references/vscode-api#SecretStorage) — OS keychain-backed — and passed as **environment variables**, so they never reach your shell history, the process list, or a log. Values are never rendered back into the view; only names are.

Remove the guarantee that secrets never reach a log.

Secrets are not included in shell history or command-line arguments. Build tools and child processes can still log environment variables, so protect them accordingly.

Three screenshots from a real Extension Development Host: the Build dock beside
the graph, the target tree next to the C# that declares it, and the Run
Configuration form with a parameter and a secret.

Linked with absolute raw URLs rather than relative paths — verified that vsce
passes those through untouched, where it rewrites relative ones to a base that
need not match this repo's default branch.

Fills the one gap in the screenshot set: PackVsix launched from the tree, ending
on Fallout's summary table with every target green. Packaging output and the
written .vsix are visible in the same frame.

npm audit fix resolves all seven within the existing ranges — lockfile only, no
manifest change. Two of them shipped: dompurify's XSS and mermaid's prototype
pollution both reach the graph webview, which is the one place this extension
renders anything.

Mermaid moves 11.16.0 -> 11.17.2, so the dist path .vscodeignore whitelists is
unchanged and the bundle still ships.
