Constellation 0.27.0 — Development preview

Constellation 0.27.0, build 39 is a development preview for creating and editing native Splunk Dashboard Studio dashboards through conversation and a live canvas.

Changes since 0.19.1

• Improve field-backed starting questions and follow-ons using recorded units, missing-data context and inspected source evidence.
• Expand guarded multi-page creation and focused navigation, calculation and formatting edits while preserving unrelated native properties.
• Recover original validated agent replies after interrupted delivery without replaying inference. Restore bounded pending draft changes after refresh, retain revision conflicts and support cooperative cancellation.
• Avoid an extra model request for a narrowly recognized fresh-table eval formatting error. Creation guidance now explains assignment separators and string quoting. Actual native search, output, measurement and preservation validation remain mandatory; UI controls and recovery budgets are unchanged.

Downloads and upgrade

• constellation-0.27.0.tar.gz — installable Splunk app; verified free of macOS files, AppleDouble files and extended archive metadata.
• constellation-0.27.0-handoff.zip — the same app bytes plus the user guide and installation, provider, security, validation and upgrade documentation. The embedded app uses the equivalent .tgz extension.
• constellation-0.27.0-user-guide.md — standalone user guide; use the handoff bundle for companion documents.
• SHA256SUMS — SHA-256 checksums for all three downloads.

Install/update through Splunk app management, then refresh existing workspace tabs. Draft schema remains 3; this update requires no draft or credential migration. See the upgrade guide, installation guide and AITK setup.

Validation and limits

This release is pinned to commit 0af82498eb0dfdce32ef7a8a82f65e4bb8b713ea. The installable archive is SHA-256 cb4b107ff9eca13db89199c34d23f09e2396417d4233854d8146b030133dc5d1. The exact archive was installed on Enterprise 10.2.8 and 10.4.4 without restart.

The Enterprise 10.2.8 / Studio 1.23.12 ordinary-user soak ran at least 30 minutes per provider against CPU, reachability and freezer data: 82 complete flows / 328 accepted turns across OpenAI, Ollama and managed AITK. All flows passed; no eval-syntax repairs appeared. AITK repaired two output-field problems and OpenAI repaired one native-search failure. Median creation was 28.82 seconds for OpenAI, 24.95 for Ollama and 28.11 for AITK; AITK's maximum was 68.23 seconds. These are operated task observations, not provider-wide success rates or a controlled latency comparison.

Independent synthetic probes checked 327 final source transformations, missing values, the 150°F exclusion and independent Wi-Fi readings. Fifteen controlled original-response losses and six cancellation checks passed. Browser checks verified selected-chart chat edits, refresh persistence and preview/native drilldowns. Temporary accounts and the copied test key were removed; original administrator work and protected AITK settings remained unchanged.

CI passed: 380 Python tests on each of Python 3.9 and 3.13, 105 frontend tests, production build/package and full-history secret scanning. Local AppInspect 4.3.1 precert reported zero errors/failures/future failures, seven warnings and one skip. The bundle-size warning remains.

This is not version 1.0, production qualification or Splunk Cloud certification. Implicit Overview/detail scoping, remaining output-field repairs, broader native/SPL2 semantics, second-target provider journeys, longer/deployment/cluster testing, independent delivery/tab-storage review and unaided usability/accessibility remain open. See the full validation record for exact evidence and limits. The repository remains private; no first-party open-source license has been selected.

Dependency notices · October 29, 2026

This historical installer uses the same pinned non-development dependency paths, versions and integrity records as 1.0.0. The added THIRD_PARTY_NOTICES.zip supplies upstream notices omitted by the original collector; keep it with redistributed copies. Original installer, handoff, guide and runtime tag bytes are unchanged. SHA256SUMS now also covers the supplement. The maintained release line is 1.x. See the notice sources.
