Security

• Logger BEARER token redaction hardened — word-boundary matching, 20+ char length floor, provider-pattern dedup; WHOLE vs SUBSTRING pattern split for provider tokens vs API tokens (src/utils/logger.ts)
• Logger console output redaction — src/utils/logger.ts redacts tokens/keys/passwords in console output (covers console.log/console.error/stderr)
• applyWindowsAcl sensitivity-graded policy — secret ACL failures throw (fail-closed), state ACL failures warn; net strengthen of file permission hardening
• Dev vulnerability advisories remediated — package-lock.json reconciliation (41b25f6)

Fixed

• Test-env detection hardened — applyWindowsAcl now requires explicit KASTELL_TEST_MODE=1 opt-in (no more path-based heuristic that silently skipped ACL hardening under temp KASTELL_DIR); P119-class recurrence fix
• Command hints routed to stderr — interactive menu prompt messages no longer pollute stdout; clean snapshot tests + correct log level separation (P147)
• In-source audit count strings aligned — describeAuditCatalog cached count now matches release-facing count; eliminates drift between menu catalog and CLI help (P147)
• Release-facing audit counts aligned with cached describeAuditCatalog output (P147)
• Linux parity gate — openssh-client install in scripts/test-linux-parity.sh (P147)
• applyWindowsAcl cause wrap — non-Error CommandFailure.cause defensively wrapped (P146/simplify)
• runLifecycleStep consolidation — runForwardStep/runRollbackStep inlined (P146/simplify)
• Command boundary JSON output cleaned for predictable CLI output (P146)
• Doctor command refactored with withMachineMode helper + applyWindowsAcl isTestEnvironmentDir check lifted (P146/simplify)
• Windows ACL principal removal batched for performance (P146)
• Probe bootstrap maintenance API collapsed to single surface (P147)
• Probe diagnostics digestOnce — Promise lazy-init eliminates eager computation (P147 perf)
• Audit catalog memoization — describeAuditCatalog cached + live mocks (P147)
• Code-review findings applied — security + drift + perf issues remediated (153c715)

Added

• withMachineMode helper for test/lock state propagation (src/core/doctor.ts)
• Plugin SDK v3 — apiVersion: "2" required, object-shaped checkCommand: { kind, cmd }, per-check mutates flag replaces manifest-level
• Probe system — src/core/probe/{context,executor,diagnostics,payload,sessionStore,types}.ts for active plugin probe sessions with budget tracking, retention, concurrency control
• Plugin SDK test fixtures — kastell-plugin-v2-mutate-bad, kastell-plugin-v2-rawfix-bad, kastell-plugin-v2-readonly, kastell-plugin-mock for SDK contract validation
• Windows ACL test coverage — tests/integration/windows-acl.test.ts for applyWindowsAcl happy path + failure paths + cached path
• Logger redaction depth test — tests/unit/logger-redact-depth.test.ts for WHOLE/SUBSTRING split verification
• Boot catch-block + strict-mode direct-path coverage for probe bootstrap (P147)
• Empty-string + circular-context logger.error coverage (P147)
• Diagnostics.ts branch coverage gaps filled (P147)
• isTestEnvironmentDir helper exported from applyWindowsAcl (P146)

Changed

• chunkConcurrent replaces p-limit in fleet.ts (p-limit dependency dropped)
• serverCompare outputSchema uses discriminatedUnion (outer shape unchanged)
• PluginRegistryEntry is now a discriminated union (loaded/error/disabled)
• CI workflow — build artifact shared between jobs (~30s saving per run)
• Plugin parallel audit — cap=3 (configurable via PLUGIN_AUDIT_PARALLELISM), aggregate timeout (PLUGIN_AUDIT_TOTAL_TIMEOUT_MS, default 120s)
• File-mtime cache for getServers() and loadLatestAudit(ip) with network FS guard
• MCP SDK round-trip test for serverCompare schema (tests/unit/mcp/mcp-registration.test.ts)

Removed

• p-limit npm dependency (replaced by internal chunkConcurrent)
• Plugin manifest-level mutates and safeToParallel flags (moved to per-check checkCommand.mutates)
