Summary

  • Comprehensive spec-to-SDK alignment audit comparing every normative requirement in mcp-protocol.md against the Python SDK's MCP modules
  • §7.3–7.6 cross-society normative requirements: 0 of 20 implemented (entire cross-society envelope absent — structural gap from v0.1.3 amendment post-dating SDK)
  • §1–§12 intra-society data types: 15 of 25 implemented (good coverage of communication patterns, context headers, resource types, metering, sessions)
  • MCP server (mcp_server.py) doesn't use SDK's own MCP types from mcp.pydogfooding gap
  • 6 internal consistency issues in the spec identified (all LOW-MEDIUM severity)
  • Prioritized 15-item work queue produced: 7 autonomous-actionable foundation types, 4 design-decision items, 4 externally-blocked items
  • Autonomous-pickable candidate C1+C2 from Sprint 52 consolidation memo (PR docs(audits): Sprint 52 conformance-gap consolidation #190)

Test plan

  • Verify audit memo content accuracy against mcp-protocol.md sections
  • Verify SDK module references are correct
  • Review prioritized work queue for sprint planning

🤖 Generated with Claude Code

Audit every normative requirement in mcp-protocol.md against the Python
SDK's MCP modules (mcp.py, protocol.py, mcp_server.py).

Key findings:
- §7.3–7.6 cross-society normative requirements: 0 of 20 implemented
  (entire cross-society envelope absent — structural gap, not accidental)
- §1–§12 intra-society data types: 15 of 25 implemented
- MCP server doesn't use SDK's own MCP types (dogfooding gap)
- 6 internal consistency issues in spec (all LOW-MEDIUM severity)
- Prioritized 15-item work queue: 7 autonomous-actionable foundation
  types, 4 design-decision items, 4 externally-blocked items

Autonomous-pickable candidate C1+C2 from Sprint 52 consolidation memo.

APPROVED: Sprint 54 candidate C1 (traced to merged PR #190). Pure analytical memo, single file (docs/audits/mcp-protocol-sdk-alignment-2026-05-15.md). Maps every §7.3–7.6 normative requirement to SDK status (0/20 implemented — structural v0.1.3 gap), plus §1–§12 coverage matrix and prioritized work queue. No SDK/spec/test code touched, no drift, orthogonal to C2/#193. Development-phase analysis advancing project goals.

…F3/F4/F12) (#200)

Addresses 4 HIGH findings from the mcp-protocol.md internal-consistency audit
(merged as PR #192, docs/audits/mcp-protocol-internal-consistency-2026-05-15.md):

F2: §7.4 MUST for exchange_rate depended on non-dependable §7.7. Replaced with
    conditional MUST on atp_settlement presence + interim conformance note.
F3: §7.4 example used scalar bilateral model §7.7.1 explicitly rejects. Replaced
    with referent-grounded schema (dual amounts + referent + agreement ref).
F4: atp_settlement lacked referent slot. Now carries caller/responder currencies,
    amounts, referent object, and exchange_agreement_ref — forward-compatible with
    §7.7.3 acceptance payload.
F12: §7.7 conformance status undeterminable. Added per-subsection markers:
     §7.7.1/§7.7.4 Normative, §7.7.2/§7.7.3/§7.7.7 Normative-draft,
     §7.7.5/§7.7.6 Informative.

Continues the spec-fix stream from operator commit 2e1e8b1 (F8 resolution).
