🔴 (20:47) In packages/cli/src/lib/version-check.ts, checkForUpdateInBackgroundImpl(): void is a non-blocking background version check. It never throws: errors are caught and reported to Sentry.

🔴 (20:47) checkForUpdateInBackgroundImpl() calls shouldCheckForUpdate() inside a synchronous try; DB-access failures are handled with Sentry.captureException(error) and an immediate return so the CLI does not crash.

🔴 (20:47) checkForUpdateInBackgroundImpl() creates pendingAbortController = new AbortController(), gets channel from getReleaseChannel(), and starts a forced transaction with Sentry.startSpanManual({ name: "version-check", op: "version.check", forceTransaction: true }, ...).

🔴 (20:47) The version-check span uses fetchLatestNightlyVersion(signal) for channel "nightly" and fetchLatestFromGitHub(signal) for stable, then calls setVersionCheckInfo(latestVersion) and maybePrefetchPatches(channel, latestVersion, signal) so sentry cli upgrade can apply prefetched delta patches offline.

🔴 (20:47) Version-check abort errors are expected on process exit and are not reported; other Error instances are stored as span attributes version_check.error and version_check.error_type rather than sent through captureException, keeping transient GitHub rate-limit/CDN/network/JSON failures queryable in Discover without cluttering the Issues feed.

🔴 (20:47) The version-check span uses status code 1 for OK and 2 for Error; its finally block sets pendingAbortController = null and calls span.end().

🔴 (20:47) isStderrTTY(): boolean in packages/cli/src/lib/version-check.ts returns Boolean(process.stderr.isTTY); update banners are suppressed for non-TTY stderr such as pipelines, CI logs, and editor-captured output, matching gh CLI behavior.

🔴 (20:47) At the inspected worktree state, .lore.md was modified, the branch was chore/preshape-monorepo, and the displayed commit was 605e8318d1f3.

🔴 (20:48) packages/cli/vitest.config.ts defines requireJsToTsPlugin(), a pre-enforced Vite plugin named "require-js-to-ts" that rewrites lazy relative require("./path.js") calls in .ts source to absolute .ts paths only when the target exists; this is needed because Node.js require() bypasses Vite’s resolver and resolve.extensions.

🔴 (20:48) requireJsToTsPlugin() detects .ts modules containing require(, uses regex /require$["'](\.[\w/.]+)\.js["']$/g, checks targets with existsSync(join(dirname(id), \${relPath}.ts`)), and returns { code: transformed, map: null }` only when a replacement occurred.

🔴 (20:48) packages/cli/vitest.config.ts also defines pre-enforced plugin jsToTsResolvePlugin() named "js-to-ts-resolve"; for relative .js imports with an importer, it replaces the .js suffix using JS_EXT_RE = /\.js$/, resolves against dirname(importer), and returns the existing .ts path.

🔴 (20:48) Vitest uses plugins in order [requireJsToTsPlugin(), jsToTsResolvePlugin()], resolution extensions [".ts", ".tsx", ".js", ".jsx", ".json"], conditions ["import", "module", "default"], setup file ./test/preload.ts, timeout 15_000, isolate: true, pool "forks", fork execArgv: [], and fork environment { UV_USE_IO_URING: "0" }.

🔴 (20:48) Vitest includes test/**/*.test.ts and test/**/*.test.tsx, excludes **/node_modules/** and **/dist/**, and uses coverage reporter ["lcov"].

🔴 (20:48) Vitest inlines @sentry/node-core, @sentry/core, @clack/prompts, and node:child_process under server.deps.inline so vi.spyOn can intercept exports instead of failing on frozen ESM namespace objects with "Cannot redefine property".

🔴 (20:48) Vitest sets mockReset: false; the accompanying rationale says hoisted vi.mock() mode must intercept all module bindings so a namespace vi.spyOn affects bindings observed by source modules at call time.

🔴 (20:48) In packages/cli/script/generate-docs-sections.ts, generated development prerequisites interpolate extractDevNodeVersion() and extractPnpmVersion() into Node.js and pnpm minimum-version bullets.

🔴 (20:48) packages/cli/script/generate-docs-sections.ts registers generated sections in this visible order: DEVELOPMENT.md section dev-prereq via generateDevPrereqDevelopment; DEVELOPMENT.md section build-toolchain via generateBuildToolchain; ${DOCS_CONTENT}/contributing.md section build-commands via generateBuildCommands; README.md section dev-scripts via generateDevScripts; DEVELOPMENT.md section dev-env-vars via generateDevEnvVarsTable; ${DOCS_CONTENT}/self-hosted.md section self-hosted-env-vars via generateSelfHostedEnvVarsTable; ${DOCS_CONTENT}/getting-started.mdx section platform-support via generatePlatformSupport with markerStyle: "mdx".

🔴 (20:48) The docs generator reads each section file as UTF-8, computes section.generate(), and calls replaceMarkerSection(original, section.sectionName, generated, section.markerStyle ?? "html").

🔴 (20:48) In check mode, changed generated docs print STALE: ${section.filePath} [${section.sectionName}], increment staleCount, and ultimately print ${staleCount} section(s) are stale. Run: pnpm run generate:docs before process.exit(1); outside check mode, changed sections are written and logged as Updated: ..., unchanged sections as Up to date: ..., and completion as "All docs sections generated.".

🔴 (20:49) In packages/cli/script/generate-skill.ts, extractPackageManagerCommand(rawContent) applies PACKAGE_MANAGER_REGEX and returns capture group 1 or null.

🔴 (20:49) generateInstallSection(installSection, rawContent) emits heading ### Installation, extracts bash code blocks, adds their code in a fenced Bash block, and appends an extracted package-manager command; when both types exist, it separates them with a blank line and comment # Or install via npm/pnpm/bun.

🔴 (20:49) generateAuthSection(authSection) emits heading ### Authentication and places all extracted Bash code blocks into one fenced Bash block when any exist.

🔴 (20:49) loadPrerequisites() reads ${DOCS_PATH}/getting-started.mdx; if unavailable it returns getDefaultPrerequisites(), otherwise it strips MDX components and frontmatter, emits ## Prerequisites plus "The CLI must be installed and authenticated before use.", and derives "Install Script" and "Authentication" sections through generateInstallSection() and generateAuthSection().

🔴 (20:49) getDefaultPrerequisites() in packages/cli/script/generate-skill.ts provides installation commands curl https://cli.sentry.dev/install -fsS | bash and npm install -g sentry, then authentication commands sentry auth login, sentry auth login --token YOUR_SENTRY_API_TOKEN, and sentry auth status; OAuth login is labeled recommended.

🔴 (20:49) packages/cli/test/lib/delta-upgrade.mocked.test.ts defines BINARY_NAME = getPlatformBinaryName(), a versionHex(version) helper that concatenates padded character-code hex, and tempFile(name) paths under tmpdir() formatted as delta-iso-${Date.now()}-${Math.random().toString(36).slice(2)}-${name}.

🔴 (20:49) The visible resolveStableDelta mocked test creates temporary current and destination binary paths, writes "old binary content for testing" to the old binary, and models a stable upgrade from 0.13.0 to 0.14.0.

🔴 (20:49) The mocked stable release contains the platform binary with size 100_000, digest sha256:${versionHex("0.14.0")}, and URL https://example.com/${BINARY_NAME}; its ${BINARY_NAME}.patch asset has size 500 and GitHub Release URL; its ${BINARY_NAME}.gz asset has size 100_000.

🔴 (20:49) The mocked delta test creates a 32-byte fake TRDIFF10 patch, writes magic "TRDIFF10" at offset 0, and leaves control, diff, and new-size fields at 0; chain resolution should succeed, but patch application is expected to fail because it produces an empty output.

🔴 (20:49) packages/cli/test/e2e/delta-upgrade.test.ts tests binary patching by downloading stable versions OLD_VERSION = "0.12.0" and NEW_VERSION = "0.13.0" from GitHub Releases, generating a TRDIFF10 patch with zig-bsdiff, and verifying applyPatch() produces byte-identical output.

🔴 (20:49) The delta-upgrade E2E test uses BSDIFF_PATH = process.env.ZIG_BSDIFF_PATH ?? "/tmp/bsdiff" and is skipped through describe.skipIf(!canRun) unless that executable exists; its patching test timeout is 120_000.

🔴 (20:49) The E2E test restores real fetch from (globalThis as { __originalFetch?: typeof fetch }).__originalFetch in beforeAll() and restores the previously saved globalThis.fetch in afterAll().

🔴 (20:49) The E2E test creates a delta-e2e- temporary directory with paths old, new, patch.trdiff10, output, patch2.trdiff10, and chain-output, downloads binaries from https://github.com/getsentry/cli/releases/download/${VERSION}/${binaryName}, and runs ${BSDIFF_PATH} ${oldPath} ${newPath} ${patchPath} --use-zstd.

🔴 (20:49) The E2E test computes the expected new-binary hash with createHash("sha256"), expects the SHA-256 returned by applyPatch(oldPath, patchData, outputPath) to match, and separately checks output byte length and full byte-for-byte equality.

🔴 (20:49) The E2E two-hop chain is old --p1--> new --p2--> new; p2 is generated with ${BSDIFF_PATH} ${newPath} ${newPath} ${chainPatchPath} --use-zstd, and applyPatchChainInMemory(oldPath, [p1, p2], chainOutputPath) must return the expected SHA-256 and write bytes equal to the new binary.

🔴 (20:49) Delta-upgrade chain intermediates never touch disk; the E2E test explicitly requires ${chainOutputPath}.patching.a and ${chainOutputPath}.patching.b not to exist.

🔴 (20:49) The delta-upgrade E2E finally block attempts unlinkSync() for oldPath, newPath, patchPath, outputPath, chainPatchPath, and chainOutputPath, ignoring cleanup errors.

🔴 (20:49) The E2E downloadBinary(url, destPath) sends header "User-Agent": "sentry-cli-e2e-test" with redirect: "follow" and throws Failed to download ${url}: HTTP ${response.status} when response.ok is false.

🔴 (20:49) packages/cli/test/preload.ts deletes SENTRY_TOKEN, SENTRY_CLIENT_ID, SENTRY_URL, SENTRY_HOST, SENTRY_ORG, and SENTRY_PROJECT; it then sets a fake unit-test auth token through SENTRY_AUTH_TOKEN, disables telemetry with SENTRY_CLI_NO_TELEMETRY = "1", and disables background update checks with SENTRY_CLI_NO_UPDATE_CHECK = "1".

🔴 (20:49) packages/cli/test/preload.ts globally mocks fetch to prevent external network calls in unit tests; unmocked requests log [TEST] Unexpected fetch call to: ${url} and [TEST] Tests should mock fetch or use SENTRY_TEST_* credentials for real API calls, then throw Unmocked fetch call to: ${url}.

🔴 (20:49) The preload fetch mock normalizes string, URL, and Request inputs through getUrlFromInput(input), assigns the mock with an unknown cast to avoid Bun’s extended fetch type including preconnect, and preserves the original fetch at globalThis.__originalFetch for tests needing real HTTP.

🔴 (20:49) packages/cli/test/preload.ts registers a process "exit" cleanup that calls rmSync(testDir, { recursive: true, force: true }) and ignores cleanup errors.
