⚠ Release note for publish.yml: the release-notes extractor (an awk script in publish.yml) prints every line between the first and second ## [ headers. When cutting a release, fold the entries under ## [Unreleased] into the new ## [X.Y.Z] — <date> section above Unreleased, or remove the Unreleased block for the release commit. Otherwise the GitHub release ships boilerplate.

[Unreleased]

Fixed

• Welcome panel stops lying after an LSP crash. Subscribe to client.onDidChangeState so a mid-session server crash (or the LanguageClient's auto-restart exhausting) flips pipelineCheck.lspReady back to false. Previously the panel kept showing "Scan workspace" after the LSP died — the button still worked, it just opened files against a dead server.
• disabledProviders now silences lowercase dockerfile / jenkinsfile. The internal glob matcher in providerForPath was case-sensitive against **/Dockerfile, so files written in lowercase (common on Windows case-preserving filesystems) classified as undefined and slipped past the user's disable filter.
• Activation no longer hangs on a misconfigured serverArgs. client.start() is now raced against a 30-second timeout. An empty pipelineCheck.serverArgs used to drop the Python child into the REPL where it waited on stdin forever; activation would stay half-pending and the welcome panel would never leave the install prompt. On timeout we kill the stranded subprocess and surface the same "Install in terminal / Open server log" toast the LSP-failure path uses.
• Scan workspace no longer claims success against a dead LSP. The scan command now gates on isLspReady() and surfaces a warning toast with Install in terminal / Restart language server / Open server log when the LSP is down. Quiet mode (scan-on-save) stays silent. Previously the scan would openTextDocument every candidate file, publish no diagnostics, and finish with a "scanned N files" toast even though no LSP was alive to produce findings.

[1.0.0] — 2026-05-19

First stable release. Closes the v0.x line: the Findings tree has its remaining affordances (filter, non-preview open, scan-on-save), the release-tooling and repo-security work is fully landed (SHAs pinned on every action, GITHUB_TOKEN locked out of .git/config, Private Vulnerability Reporting + Discussions enabled, production environment gate, npm audit + dependency-review + CodeQL on every push), and the internal eslint stack is on v9 flat config so future toolchain bumps have a clean ramp. No telemetry — see SECURITY.md.

Added

• Pipeline-Check: Filter Findings command. Opens an InputBox; matches against rule ID, message body, and file path (case-insensitive substring). Re-invoking the command pre-fills the current filter so users can edit or clear (empty input clears). New $(filter) button on the Findings view title bar. The badge updates to reflect the filtered count; the lastFindingUris set still tracks the unfiltered universe so a publish for a currently-hidden finding still wakes the tree up.
• Pipeline-Check: Open Finding context-menu entry on Findings tree leaves. Opens the finding as a permanent (non-preview) tab — useful when triaging multiple findings side-by-side. The default click-to-reveal still uses preview-style so the common "click through to scan" flow doesn't create tab clutter.
• Scan-on-save mode. New pipelineCheck.scanOnSave setting (default false). When enabled, saving a CI/CD config file triggers a quiet workspace re-scan — the LSP already re-publishes diagnostics for the saved file itself on didSave, so this picks up cross-file effects in other CI files that aren't currently open (a Jenkinsfile that includes the just-edited shared library, a GHA workflow that calls the just-edited composite action). Renders as a status-bar spinner with no completion toast; an in-flight guard collapses save-storms (autosave, Save All) to a single scan. (R29)
• Status bar background colour reflects severity. A workspace with any CRITICAL finding tints the bar to statusBarItem.errorBackground (red in the default themes); a workspace with HIGH but no CRITICAL tints to statusBarItem.warningBackground (yellow). MEDIUM / LOW / INFO keep the default fg colour so a "1 medium" workspace doesn't shout. Same ThemeColor tokens ESLint and Error Lens use, so the visual language reads correctly to any existing VS Code user.
• "What's new" notification on upgrade. First activation after a version bump shows a one-time toast — "Pipeline-Check 0.X.Y is here …" — with a "See release notes" button that opens the matching GitHub release. Persists the seen-version before showing so a missed dismissal doesn't loop next launch. Suppressed when the stored version equals the manifest version (same launch).
• Pipeline-Check: Scan Workspace command. Walks every CI/config file in the workspace (matching the same patterns the LSP's documentSelector uses), opens each via vscode.workspace.openTextDocument so the LSP's didOpen pipeline picks them up, and lets the Findings panel re-render from the diagnostic stream as scans complete. Progress toast with cancellation; partial failures (read errors, unsupported encodings) are counted but don't abort the scan. Surfaced from a $(play) button on the Findings view title bar, the Command Palette, and a link in the Findings welcome state. (R10, R15)

Changed

• Quieter clipboard confirmations. Copy Rule ID and Copy LSP Install Command now write a 2-second status-bar message instead of firing a modal information toast. The copy still succeeded silently 95% of the time anyway; this confirms the action without stealing focus.
• "Refresh Findings" now triggers a real scan instead of just re-painting the tree from already-published diagnostics. Matches the user's mental model: clicking a refresh icon should fetch new data, not re-render stale data. (R10)
• SCAN_PATTERNS removed in favour of TRIGGER_PATTERNS from providers.ts. The single source of truth for which files are CI-relevant now drives the documentSelector, the activationEvents, and the workspace scan — three surfaces that used to drift apart.
• ESLint migrated to v9 flat config. Replaced .eslintrc.json with eslint.config.mjs; dropped @typescript-eslint/eslint-plugin + @typescript-eslint/parser in favour of the unified typescript-eslint package. Rules carry over verbatim so lint results are unchanged. (R22)

[0.2.0] — 2026-05-19

Closes 24 of 29 items from the 2026-05-19 in-depth UX/code review. Adds the activity-bar Findings tree's missing affordances (status bar, CodeLens, navigation, context menus, per-provider toggles), the release-tooling polish (production environment gate, pre-release channel, three-OS CI, integration tests), and the discovery / accessibility pass.

Heads-up for users with non-standard workflow paths: the extension's activationEvents now match only the workspaceContains: patterns shared with the LSP documentSelector (plus onStartupFinished so the activity-bar slot is always visible). If your repo keeps CI definitions outside the standard locations (e.g. pipelines/build.yml instead of .github/workflows/*.yml), the extension still activates on onStartupFinished, but the LSP only scans files matching the document selector. Use pipelineCheck.serverArgs to point the LSP at a different path or symlink your custom config into a standard location.

Added

• Inline CodeLens summary. Each scanned file carries a Pipeline-Check: 2 critical · 1 high lens at line 1. Click reveals the Findings panel. Re-emits on every diagnostic publish so the text tracks the latest scan. (R26)
• Status bar item. Bottom-left of the window, shows the top two non-zero severities (e.g. $(shield) 3C 1H) with a tooltip that breaks down the full per-severity tally. Click reveals the Findings panel. (R9)
• Keyboard navigation. Alt+F8 / Shift+Alt+F8 jump between Pipeline-Check findings in editor order (fsPath ascending, then by line); wraps at both ends. Mirrors VS Code's F8 muscle memory for the global "Next Problem" command. (R12)
• Per-provider toggles. New pipelineCheck.disabledProviders setting silences whole providers. dockerfile covers both Dockerfile and Containerfile (same syntax). Useful in a monorepo where Pipeline-Check would otherwise lint a sub-project's Dockerfile that has its own lint pipeline. (R25)
• Rule documentation link in leaf tooltip. When the server publishes a Diagnostic.code.target URL, the Findings tree's leaf tooltip appends a clickable $(book) <rule-id> documentation link below the message body. (R8)
• Client-side structured logging. The extension's output channel now interleaves [client] HH:MM:SS.mmm lines around activation and command invocations with the LSP's window/logMessage traffic. Easier to triage bug reports — start/ok/failed breadcrumbs land in the same surface users already focus via Show language server output. (R16)
• Pre-release channel. Tags like v0.2.0-rc.1 ship to the marketplace pre-release channel; the matching GitHub release is marked prerelease. Detection is by the presence of a - after the semver core. (R24)
• Right-click context menu on Findings tree leaves. Open Rule Documentation opens the URL the server published via Diagnostic.code.target in the system browser; Copy Rule ID writes the rule's identifier to the clipboard. Same data the leaf tooltip already surfaces, now available without keeping the tooltip open.
• pipelineCheck.codeLens.enabled setting. Defaults to true. Hides the line-1 file-summary CodeLens for users who find it intrusive without disabling CodeLens globally. Toggle takes effect on the next render — no extension restart.
• pipelineCheck.copyInstallCommand command. Copies pip install "pipeline-check[lsp]" to the clipboard. Surfaced from the Findings welcome state and from the Command Palette so users can re-find it after dismissing the first-run error toast.

Changed

• Welcome state of the Findings panel teaches. Now leads with what Pipeline-Check does + a Copy install command link for the Python [lsp] extra, then onboarding ("open a workflow…"), then the Alt+F8 / Shift+Alt+F8 keyboard hint, then a --- separator and the recovery actions (Restart, Open Log) demoted below.

• onStartupFinished activation event. The extension now wakes up after VS Code's start-up barrier so the activity-bar slot is visible in every workspace — not just ones with a workspaceContains: match. The LSP child process still only spawns when the documentSelector matches an open document, so there's no idle-Python-process cost.

• Status bar item hides in non-CI workspaces. On activation we do a one-shot findFiles for any of the trigger patterns; the status bar item only shows once we've seen evidence the workspace is CI-relevant (either a match or an actual diagnostic publish). Stops $(shield) clean cluttering the bottom-left in frontend projects that happen to have Pipeline-Check installed alongside other linters.

• Status bar accessibility label. Screen readers now hear "Pipeline-Check: 3 critical, 1 high" instead of the codicon shortcode + letter-by-letter abbreviation.

• Status bar tooltip teaches Alt+F8. The trailing line of the tooltip ("Alt+F8 / Shift+Alt+F8 to step through findings") is the primary discovery surface for the navigation keybindings.

• Command titles use title case for VS Code's convention: "Restart Language Server", "Show Language Server Output", "Refresh Findings". Existing "Go to Next Finding" and "Change Grouping" stay the same. Command IDs are unchanged — settings, keybindings, and automation continue to work.

• @vscode/test-electron integration suite now runs in CI (Linux only, via xvfb-run -a). Five tests pin activation, the command-registration contract, the Findings view registration, the configuration schema completeness, and the workspace-trust capability declarations. Catches what unit tests can only approximate. (R17)

• Three-OS test matrix — [ubuntu-latest, windows-latest, macos-latest]. The LSP child-process spawn path is Windows-sensitive; matrix CI catches the LF/CRLF and path-separator bugs single-OS CI silently misses. (R21)

• Activation surface narrowed. Triggers are workspaceContains: patterns matching the providers we actually scan (the documentSelector uses the same patterns). Opening an unrelated package.json or mkdocs.yml no longer wakes up the extension. (H4)

• Trigger-pattern list lives in one place. Extracted into src/providers.ts as a single PROVIDERS map; the documentSelector, activationEvents, and the LSP middleware's per-provider filter all read from it. A regression test asserts the manifest's activationEvents stay in lockstep with the patterns. (R14)

• Shared vi.mock("vscode") factory under src/__testStubs__/. Unit tests now share a single stub instead of redefining the surface per file. (R18)

• Marketplace description length gated in CI at the 145-character truncation point so future edits don't blow it. (R20)

Fixed

• Restart language server toast no longer fires on failure — if the server failed to come up, the error notification already carries the install hint; the success toast used to fire too, giving the user contradictory signals. (R2)
• stopClient has a 2-second hard ceiling on the LSP child's shutdown. A deadlocked server used to hold the deactivate path indefinitely; VS Code reported "Window not responding" until the user force-quit. (R3)
• groupByFile no longer round-trips Uri through string for every group node. Bucket value carries the original Uri. (R4)
• compareByLocation sorts on fsPath instead of the full URI string. Cross-scheme entries (file:// vs untitled://) no longer bunch at one end. (R5)
• collectFindings is memoised per refresh — buildRoot and updateBadge used to walk the global diagnostic store twice per refresh. (R6)
• onDidChangeDiagnostics skips refreshes from unrelated publishers. ESLint / mypy / redhat.yaml keystroke chatter no longer rebuilds the tree. The skip-check also catches clears (a stale leaf can't outlive a cleared file). (R7)

[0.1.1] — 2026-05-19

Production-readiness pass. v0.1.0 was effectively unusable on a clean install (see Fixed below); v0.1.1 is the first release that actually loads in VS Code. Also lands the Findings panel and the security hardening from the pre-marketplace review.

Added

• Findings panel. A dedicated activity-bar slot ("Pipeline-Check" — custom inverted-Y pipeline glyph at media/pipeline-check.svg) carries a Findings tree that re-groups the diagnostics the LSP server has already published. Strictly a re-presentation: never triggers its own scan, so the thin-transport-adapter promise in extension.ts stays intact. The activity-bar icon carries a live count badge so "how many findings does this workspace have right now?" is answerable without expanding the panel. Three group modes — severity (default), file, rule — are switched via a Change Grouping Quick Pick that marks the active mode with $(check). Each leaf renders as the rule title plus a RULE · file:LINE description that drops whichever component is already implied by the parent group; clicking opens the file at the diagnostic range. CRITICAL is rendered as flame and HIGH as error so the two distinguish in the severity-grouped tree without breaking parity with the editor gutter (which has no "more red than red" state); INFO uses circle-outline themed to descriptionForeground so it is visibly the quietest row instead of inheriting the default foreground. The welcome state leads with what the extension does rather than what is missing; the diagnostic recovery links sit on a secondary "Not seeing findings?" line.

• pipelineCheck.severityThreshold setting. A new enum knob (low / medium / high / critical, default low) that mirrors the CLI's --severity-threshold. Drives a client-side handleDiagnostics middleware that filters out diagnostics whose upstream pipeline-check severity falls below the threshold before they reach the gutter or Problems panel, so the editor surface can be tuned independently of the CLI's report. The filter reads Diagnostic.data["severity"] (set by the v1.0.6 server) so it can distinguish CRITICAL from HIGH (both map to LSP Error). Diagnostics without the data.severity metadata pass through unconditionally, so an older server (or a non-pipeline-check publish) is never hidden.

Security

• pipelineCheck.serverCommand and pipelineCheck.serverArgs are now machine-overridable. Workspace overrides require an explicit prompt, so a malicious .vscode/settings.json can't silently swap the interpreter or inject -c "<code>" once the user trusts the workspace.
• Declared capabilities.untrustedWorkspaces: "limited" and virtualWorkspaces: false. The extension stays inactive in untrusted workspaces until the user trusts them, so the LSP child process never spawns from a freshly-cloned, untrusted repo.
• Hardened the publish workflow. Pinned @vscode/vsce and ovsx to specific versions (no more @latest with PATs in env), added a git merge-base check that refuses to publish a tag that isn't on main, added a CHANGELOG-fold check, and narrowed workflow-level permissions to contents: read with the publish job opting up to contents: write. The publish job is gated on the production GitHub Environment so VSCE_PAT / OVSX_PAT are only readable from a run that has cleared required reviewers.
• Added SECURITY.md with GitHub Private Vulnerability Reporting as the disclosure channel, response SLAs, and a published threat model.

Tests

• Vitest unit suite added. 25 tests covering the severity threshold filter (extracted into src/severityFilter.ts) and the Findings tree's pure logic (collection from diagnostics, group-by-severity / file / rule, severity normalisation, no-refresh-storm contract). npm test runs the suite; both ci.yml and publish.yml gate on it. Test files live next to the code they cover and are stripped from the .vsix.

Fixed

• The published .vsix was missing its runtime dependency. The previous build emitted out/extension.js via tsc but excluded node_modules/ from the package, so require("vscode-languageclient/node") threw on activation in a clean install. Now bundled with esbuild into a single dist/extension.js (the only JS in the .vsix); a CI smoke step (scripts/smoke.js) stubs the vscode module, loads the bundle, and asserts activate / deactivate are exported so this regression class fails the build instead of the user.

Changed

• npm audit --omit=dev --audit-level=high now runs on every push to main so advisories filed after a PR has merged still surface.

• Activation tightened. The extension used to activate on every YAML / JSON / Dockerfile / Terraform / Groovy file in any workspace, then rely on the server's content filter to drop unrelated documents. activationEvents is now a workspaceContains: list of the trigger files we actually scan (.github/workflows/*, .gitlab-ci.yml, azure-pipelines.yml, etc.). The LSP's documentSelector is switched from language IDs to matching file-path globs, so the server only sees candidate documents — no more spurious activations on package.json, mkdocs.yml, or a Helm values.yaml.

• @vscode/vsce and ovsx are pinned devDependencies. Workflows invoke them via the locally-installed binaries (npx vsce, npx ovsx) after npm ci. Versions live in package-lock.json and Dependabot's existing npm config keeps them current.

• Marketplace metadata polish. Added Other to categories, pointed qna at the repo Discussions page.

• Marketplace polish pass. The package.json description is rewritten so the numbers that differentiate this extension (22 providers, 14 compliance frameworks beyond OWASP Top 10 CI/CD, 810+ rules) land in the first 100 characters and survive the ~145-character truncation the marketplace search results impose. Command titles renamed to Restart language server and Show language server output so the palette entries are self-disambiguating without leaning on the Pipeline-Check category prefix. Every configuration setting switched from description to markdownDescription so backtick'd literals (python, python -m pipeline_check.lsp) render as code in the Settings UI rather than plain quoted text.

• README restructured for the marketplace listing. The first paragraph carries the same numbers as the marketplace description, followed by a What it scans provider table (the differentiating content that prospective users land on the listing to see). Dropped the ## Status section (the marketplace already shows the version in the listing's metadata bar). Collapsed the architecture diagram behind a <details> block near the bottom of the page; it's a useful engineering reference but not the first scroll of a marketplace listing.

• Start-failure notification carries two actions, not one. When python -m pipeline_check.lsp fails to launch (Python missing from PATH, [lsp] extra not installed, server crash on import), the notification now exposes Copy install command alongside Open server log. The user can act on either without re-reading the message body. Notification copy stripped of the redundant Pipeline-Check: prefix that the notification chrome already shows.

[0.1.0] — 2026-05-18

First public release. Wires the editor surface to the upstream pipeline_check.lsp server.

Added

• TypeScript LSP client that spawns python -m pipeline_check.lsp over stdio (vscode-languageclient v9). Document selector covers YAML, JSON, Dockerfile, Terraform, and Groovy files; the server filters further by path and content so unrelated documents are not analyzed.
• Pilot provider coverage: GitHub Actions, GitLab CI, Azure Pipelines, Bitbucket Pipelines, CircleCI, Google Cloud Build, Buildkite, Drone, Jenkins, and Dockerfile. Multi-file / context-heavy providers (Kubernetes, Helm, Terraform plans, live AWS, CloudFormation, SCM posture) follow in a later release.
• Three configuration knobs: pipelineCheck.serverCommand, pipelineCheck.serverArgs, and pipelineCheck.trace.server for overriding the Python interpreter, module path, and LSP trace level.
• Two commands under the Pipeline-Check category:
  • Restart server — stops the running client and respawns.
  • Show server log — focuses the Pipeline-Check output channel where window/logMessage traffic lands.
• Graceful start-failure handling: when python -m pipeline_check.lsp fails (Python not on PATH, [lsp] extra not installed, server crash on import), the editor surfaces a notification with the install hint plus an Open server log button.
• Two F5 debug profiles in .vscode/launch.json:
  • Run Extension — fresh extension-host window, no workspace.
  • Run Extension (sample workflow) — opens test-fixtures/sample-workflow/ with a deliberately-vulnerable GitHub Actions workflow that fires GHA-001, GHA-004, GHA-015, and GHA-016 on open.

Requirements

• VS Code 1.85+.
• Python 3.11+ with pipeline-check[lsp] installed:

  pip install "pipeline-check[lsp]"
