Subject: [PATCH 1/7] feat: VS Code extension for inline security warnings
Adds a TypeScript extension (vscode-extension/) that scans files on
save against the local KShield backend and surfaces findings as
editor diagnostics, hover explanations, and Quick Fix actions (apply
patch / suppress rule), mirroring the API contract already used by
the Rust CLI (cli/src/types.rs, cli/src/http.rs).
Verified end-to-end against a live backend: scan-on-save, diagnostic
squiggles, hover tooltips, and Quick Fix patch application all work.
Closes #5

+- **VS Code extension** (`vscode-extension/`): inline security warnings as you type. Scans on file save (debounced), surfaces findings as editor diagnostics with hover explanations, and offers Quick Fix actions to apply remediation patches or suppress a rule globally. Talks to the same local backend the CLI manages.

+# KShield for VS Code
+
+Inline security warnings as you type, powered by your local KShield backend — the same engine the pre-commit hook uses, just faster feedback.
+
+## What it does
+
+- Scans a file every time you save it (debounced, so rapid saves don't spam the backend).
+- Shows findings as squiggles in the editor — red for CRITICAL/HIGH, yellow for MEDIUM, blue for LOW.
+- Hover over a squiggle for the finding's description and an ELI5 explanation of the fix.
+- Quick Fix (💡) actions let you apply the suggested patch or suppress a rule type globally, without leaving the editor.
+- A status bar item shows whether the KShield backend is reachable.
+
+## Requirements
+
+The extension talks to the KShield backend over HTTP — it does not bundle or start it. Start the backend first:
+
+```bash
+kshield start
+# or, from a clone of this repo:
+cd backend && SQLITE_FALLBACK=true uvicorn app.main:app --port 8000
+```
+
+## Settings
+
+| Setting | Default | Description |
+|---|---|---|
+| `kshield.enabled` | `true` | Enable/disable inline scanning. |
+| `kshield.backendUrl` | `http://127.0.0.1:8000` | Base URL of the KShield backend. |
+| `kshield.scanOnSave` | `true` | Scan automatically on save. |
+| `kshield.debounceMs` | `800` | Delay before a save triggers a scan. |
+
+## Commands
+
+- `KShield: Scan Current File`
+- `KShield: Apply Suggested Fix` (invoked via Quick Fix)
+- `KShield: Suppress This Rule` (invoked via Quick Fix)
+- `KShield: Check Backend Connection`
+
+## Development
+
+```bash
+npm install
+npm run compile # or npm run watch
+```
+
+Then press F5 in VS Code (with this folder open) to launch an Extension Development Host.
+
+## Known limitations
+
+- Findings are keyed by line number only — if the backend restarts mid-edit, positions may shift until the next scan.
+- Auto-apply only works for findings that include a `patch_diff` (currently Broken Access Control); other finding types surface a Quick Fix to suppress the rule instead.
+- `.kshield.yml` per-repo suppression config (read by the CLI) is not yet read by the extension — tracked as a follow-up.

Subject: [PATCH 2/7] fix: repoint all download routes to YTT-Global org, bump
to v1.1.0
install.sh, npm installer, Homebrew formula, pip URLs, the CLI's own
backend-download URL, the VS Code extension's repository link, and the
in-app Docs page all still pointed at the old YTTGlobalServices org and
404'd after the move to YTT-Global. Also fixes a Homebrew CI step that
was patching the wrong SHA-256 placeholders, rewords a few doc examples
that tripped KShield's own hallucination/secret patterns on its own
example strings, and bumps cli/Cargo.toml, npm/package.json, and
pyproject.toml to 1.1.0 so the release tag, the CLI's embedded backend
URL, and the PyPI build stay in sync.

## [Unreleased]
+## [1.1.0] — 2026-07-17
+
### Added
- **VS Code extension** (`vscode-extension/`): inline security warnings as you type. Scans on file save (debounced), surfaces findings as editor diagnostics with hover explanations, and offers Quick Fix actions to apply remediation patches or suppress a rule globally. Talks to the same local backend the CLI manages.
+- **VS Code extension packaging**: `repository` field added to `vscode-extension/package.json` and a bundled `LICENSE` so `vsce package` produces a clean `.vsix` with no warnings — installable locally via `code --install-extension` or publishable to the Marketplace.
+- **Root `LICENSE` file** (MIT) added, matching the license already declared in `pyproject.toml` and `vscode-extension/package.json`.
+- **PyPI publishing**: release pipeline now builds and publishes the backend package to PyPI on every non-prerelease tag.
+
+### Fixed
+- All download routes (curl installer, npm installer, Homebrew formula, pip package URLs, CLI's own backend-download URL, VS Code extension repository link, in-app Docs page) pointed at the old GitHub org `YTTGlobalServices` and 404'd after the org moved to `YTT-Global`. Repointed everywhere, including two spots (`cli/src/setup.rs`, `frontend/src/components/Docs.tsx`) that a prior pass missed.
+- Homebrew formula's release-CI step was patching the wrong SHA-256 placeholder strings for macOS builds, leaving stale checksums in published formula updates.
+- `backend/requirements.txt` was missing `numpy`, despite `app/engine/model.py` importing it directly — added `numpy>=1.26` as an explicit dependency instead of relying on it being pulled in transitively by `tensorflow`.

-## 6. Integrity Invariants — Never Break These
+## 6. VS Code Extension (`/vscode-extension`)
+
+**Stack:** TypeScript · VS Code Extension API · `@vscode/vsce`
+
+### File Responsibilities
+
+| File | Owns |
+|---|---|
+| `src/extension.ts` | Activation, save-watcher wiring, command registration |
+| `src/apiClient.ts` | HTTP client for the local backend (`/health`, `/api/v1/scan`, `/api/v1/suppress`) |
+| `src/diagnostics.ts` | Maps backend findings to `vscode.Diagnostic` objects |
+| `src/hoverProvider.ts` | ELI5 explanation shown on hover over a squiggle |
+| `src/codeActionProvider.ts` | Quick Fix actions — apply patch / suppress rule |
+| `src/patch.ts` | Applies unified-diff `patch_diff` strings from remediation findings |
+| `src/statusBar.ts` | Backend reachability indicator |
+
+### Extension Rules
+
+- **The extension never bundles or starts the backend.** It only talks to it over HTTP at `kshield.backendUrl` (default `http://127.0.0.1:8000`). Do not add process-spawning logic here — that belongs to the CLI (`cli/src/setup.rs`).
+- **Packaging**: `package.json` must keep a valid `repository` field and the package must ship with a `LICENSE` file (copied from the repo root) — `vsce package` treats both as required for a warning-free `.vsix`. Do not remove either without also updating `.vscodeignore`.
+- **Auto-apply is patch-only**: only findings carrying a `patch_diff` (currently Broken Access Control) can go through `codeActionProvider.ts`'s apply-fix path. All other finding types must fall back to "Suppress This Rule" — do not fabricate a patch for finding types the backend doesn't provide one for.
+- **Changing the finding schema**: if `app/api/v1/scan.py`'s response model changes, update `src/types.ts` in lockstep (mirrors the same contract used by `frontend/src/types/scan.ts` and `cli/src/types.rs`).

From 44adc10e7c8e064a327d6866689cf4d0aa35cbb2 Mon Sep 17 00:00:00 2001
From: Srikanth Bollampally
Date: Fri, 17 Jul 2026 19:06:02 -0400
Subject: [PATCH 3/7] feat: prep VS Code extension for Marketplace publish
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Adds a 256x256 icon (reused from the Tauri app icon set), a gallery
banner color/theme, bugs/homepage links, and a couple more discovery
keywords. Drops the leftover "private": true, which has no effect on
vsce but is misleading on a package meant to be publicly listed.
Verified `vsce package` still produces a clean, warning-free .vsix
with the icon bundled correctly.
Actual publish still requires a maintainer to run
`vsce login ytt-global && vsce publish` with a real Marketplace
access token — not something this environment can authenticate to.
