v0.1.1

Highlights

MCP server for heterogeneous AI validation — T1 structured reasoning, T2 cross-model evaluation, deterministic checksum. Python stdlib-only.

Changed

• README / docs polish: tool input schemas, Windows config, verification steps, reference disclaimer
• t2_protocol MCP tool description: five-level qualitative confidence (was high/medium/low)

v0.1.0 — First Public Release

Highlights

MCP server for heterogeneous AI validation — T1 structured reasoning, T2 cross-model evaluation, deterministic checksum. Python stdlib-only.

First public PyPI release under honest pre-1.0 semver (FastAPI/requests pattern).

• Reset package version to 0.1.0; protocol specification remains v2.5 (tool output semantics unchanged)
• Apache-2.0 license, PEP 639 metadata, MCP Registry + PyPI Trusted Publishing
• Yanked erroneous PyPI releases 2.5.2–2.5.4 (incorrect semver for day-one public release)

Included capabilities (protocol v2.5)

• T1: structured prompt translation (L1/L2/L3/L4)
• T2: cross-model confidence evaluation with recursion depth guard
• checksum: deterministic structural pre-validation (stdlib-only)
• Bilingual templates (en / zh), weight hints, caller-side web verification docs (v2.6)

Superseded PyPI releases (yanked)

Version	Reason
2.5.2–2.5.4	Erroneous semver; superseded by 0.1.0. Git tags v2.5.x remain as historical tombstones.

Protocol history (not package semver)

These entries document protocol specification evolution, not PyPI package versions.

Protocol v2.5.0 — 2026-06-12

• Enhanced L3 template with explicit evidence status tracking
• New tool: checksum — deterministic structural pre-validation
• Added core link exemption clarification to T1 output requirements

Protocol v2.0.0 — 2026-06-12

• Evaluation criteria weight assumption preamble
• Recursion depth detection and termination (depth ≥ 3)
• Qualitative confidence descriptors; version tag in output footer

Protocol v1.0.0 — 2026-06-10

v2.5.4

Highlights

MCP server for heterogeneous AI validation — T1 structured reasoning, T2 cross-model evaluation, deterministic checksum. Python stdlib-only.

• Relicense future releases to Apache-2.0 to align with MCP official protocol/infrastructure direction
• Update PyPI metadata to PEP 639 SPDX license fields
• Remove PyPI API-token fallback from publish workflow; use Trusted Publishing only
• Add repository and website metadata to server.json

v2.5.3

Highlights

MCP server for heterogeneous AI validation — T1 structured reasoning, T2 cross-model evaluation, deterministic checksum. Python stdlib-only.

v2.5.2

Highlights

MCP server for heterogeneous AI validation — T1 structured reasoning, T2 cross-model evaluation, deterministic checksum. Python stdlib-only.

• PyPI publish + MCP Registry metadata (server.json, publish.yml)
• README positioning vs Sequential Thinking / ThoughtProof / MCP #2574
• mcp-name ownership marker for registry verification

v2.5.1 — Initial Public Release

Highlights

MCP server for heterogeneous AI validation — T1 structured reasoning, T2 cross-model evaluation, deterministic checksum. Python stdlib-only.

[2.5.1] - 2026-06-15

• Open-source release polish: packaging (package-dir, setuptools.build_meta, main() entry point)
• Default locale is now en; zh remains fully supported
• English weight_hint aliases (fact-first, efficiency-first, etc.) match README
• Checksum error messages in English; optional counter via ~/.t1-t2-protocol
• Docs: caller-side web verification v2.6, AGENTS.md, bilingual caller-protocol
• CI: pip install -e ".[dev]" + pytest across Python 3.10–3.12
