Shards-Kernel v0.1.3

Shards-Kernel v0.1.3

Security and concurrency stabilisation for the self-hosted AI-agent authorisation and audit library.

• SK-002: reject signed-permit parameter omissions, unexpected fields, nested type mismatches and mutable-permit substitution; match exact effective tool arguments.
• SK-001: bounded single-flight admission, audited busy denials and synchronized evidence snapshots.
• Operator halt: explicitly distinguish queued (HTTP 202, nonterminal) from confirmed HALTED (HTTP 200); audit in-flight outcomes before finalisation.
• Verify Python 3.9–3.15 CI, local multi-process E2E, PostgreSQL test integration, clean installed-wheel security probes and release checks before publication.
• Retain the signed local reference operator for narrowly scoped echo/add tools; local official MCP v2 agent integration requires Python 3.11+.

Supported boundary: local, self-hosted reference control plane and Python library integrating trusted tool handlers; not an OS sandbox, remote MCP gateway, trading executor, or guarantee of exactly-once external effects.
Migration: previously published v0.1.2 does not enforce the corrected parameter and concurrency boundaries. Permit issuers must sign the exact effective parameters including handler defaults.

Includes independently checksummed Python wheel and source distribution.

Shards-Kernel v0.1.2

Shards-Kernel v0.1.2

Documentation-focused patch release incorporating the updated Shards-Kernel README into the PyPI distribution metadata. Runtime functionality is unchanged from 0.1.1.

• Python 3.9–3.12 core library; optional official MCP v2 local agent client on Python 3.11+.
• Adds the Shards-Kernel banner, MIT badge, use-case descriptions and terminal examples to the PyPI project page.
• Maintains existing strict permit, fail-closed execution and audit controls without expanding the supported local operator allowlist.
• Includes a verified Python wheel, source distribution and SHA256SUMS.

Scope: local agent integration and demonstration. This is not a deployed
remote MCP gateway, custodial wallet service, trading engine or production
certification. PyPI publishing uses the existing OIDC-verified workflow.

Install the core package directly from the attached wheel, or download
the source archive. Read README.md and docs/AGENT_QUICKSTART.md for usage.

Shards-Kernel v0.1.1

Shards-Kernel v0.1.1

Maintenance release containing verified permit, evidence, and asynchronous execution hardening.

• Python 3.9–3.12 core library; optional official MCP v2 local agent client on Python 3.11+.
• Strict effective-parameter and signed-permit binding, fail-closed evidence checks, and safe async cancellation.
• Release-gated real-process E2E coverage, dependency/security checks, offline SQLite restore rehearsal.
• Includes a verified Python wheel, source distribution and SHA256SUMS.

Scope: local agent integration and demonstration. This is not a deployed
remote MCP gateway, custodial wallet service, trading engine or production
certification. PyPI publishing uses the existing OIDC-verified workflow.

Shards-Kernel v0.1.0

Shards-Kernel v0.1.0

First versioned release of the deterministic, audited Python kernel.

• Python 3.9–3.12 core library; optional official MCP v2 local agent client on Python 3.11+.
• Locally governed agent actions, strict signed permits, replay protection and audit receipts.
• Release-gated real-process E2E coverage, dependency/security checks, offline SQLite restore rehearsal.
• Includes a verified Python wheel, source distribution and SHA256SUMS.

Scope: local agent integration and demonstration. This is not a deployed
remote MCP gateway, custodial wallet service, trading engine or production
certification. PyPI publication is intentionally not enabled.
