Release v0.3.0 - #4

Summary

• Release GERM v0.3.0 with the loopback-only Cosmoaudition bridge, explicit mappings, local archives, and dashboard modules.
• Add bounded Matter Analysis and optional MASA 0.1 sidecars while keeping Sonic Lineage sound_id canonical.
• Harden recorder shutdown, zero-gain previews, missing-data handling, spectral aggregation, lineage validation, and persisted companion state.
• Remove confirmed dead dashboard helpers and synchronize all release metadata.

Why

The recent observatory and sonic-matter work needed a complete integration pass. This release makes unavailable, errored, stale, and zero-valued observations distinct, prevents fabricated neutral values, and closes recorder and analysis reliability gaps.

Impact and boundaries

Cosmoaudition remains loopback-only. MASA sidecar failures cannot invalidate successful app work. The live external Cosmo service was intentionally absent; its unavailable state was verified. Only app code, configuration, tests, and canonical release documentation are included. No audit reports, plans, screenshots, caches, or QA artifacts are part of the commit.

Validation

• 175 pytest tests passed
• Ruff, Python compileall, dependency lock and install checks passed
• Dashboard smoke and Swift build passed
• JavaScript and shell syntax passed
• OpenAPI has 83 paths, 97 operations, and no duplicate operation IDs
• Desktop and mobile browser QA completed without console warnings or errors
• Git diff whitespace check passed

Dependency note

The core installed dependency set produced no audit finding. The optional upstream Stable Audio 3 Python provider currently pins torch 2.7.1; its current upstream main branch retains that exact pin. This release does not apply an unsupported PyTorch override that could silently break provider compatibility.
