Prosaic Runtime 0.7.1 — pure workflow admission

Exports pure validate_execution_artifact, validate_custom_tools and custom_descriptors for public workflow admission. Execution shares route, effort and provider-control validation; acquisition inherits the final agent's effective execution context. Admission invokes no models, callbacks or CLI probes.

Source/tag commit: 47ac9952638249dc78ec037a485ba5104cf1ec8c. Pins Core 0.3.2 at af7d90e178f61d53ba71bcc61c41c3ef7f941b4c.

Qualification passed:

• 495 local Runtime tests, one interpreter opt-in skip; nine focused release-wiring tests.
• Native matrix: Linux AMD64/ARM64 and macOS on Python 3.11/3.12/3.13, operational sandbox checks, PostgreSQL 16/18 recorder checks.
• Wheel/source builds, clean declared-dependency installation through immutable GitHub pins and installed native-tool workflow smoke.
• Downloaded distributions verified against SHA256SUMS-0.7.1.txt and staged bytes before publication.

Includes the unchanged-compatible PostgreSQL recorder 0.1.1 as a separately installed wheel/source distribution. Runtime owns usage evidence; authorization and customer charging remain application-owned. VERIFICATION-0.7.1.json records exact native results and artifact hashes.

Install from the immutable tag or release assets. GitHub distributes these packages; no npm or PyPI publication. Qualification uses synthetic loopback providers and does not certify production deployment or external providers.
