DIP Protocol Specification

Status: draft. Normative keywords follow RFC 2119.

The numbering follows the master build instruction, section 7. Each document states whether it describes the implementation or is still a draft.

#	Document	Status
1	Overview	Draft
2	Architecture	Matches implementation
3	Authority declaration	Matches implementation
4	Request schema	Matches implementation
5	Canonicalization	Matches implementation
6	Authorization evaluation	Matches implementation
7	Authorization state model	Draft
8	Approval workflow	Matches implementation
9	Execution boundary	Matches implementation
10	Evidence envelope	Matches implementation
11	Ledger	Matches implementation
12	Cryptography	Matches implementation
13	Trust model	Draft
14	Independent verification	Matches implementation
15	Connectors	Matches implementation; endpoints are placeholders
16	Error and reason codes	Matches implementation
17	Protocol versioning	Draft
18	Compatibility and migration	Draft
19	Security considerations	Draft
20	Threat model	Points to docs/THREAT-MODEL.md
21	Conformance	Draft; no independent implementation yet

Renumbering

Canonical encoding was section 3 in an earlier draft. It is now section 5, to match the master instruction. Code comments and the implementation matrix were updated. Historical entries in CHANGELOG.md and docs/BUILD_STATUS.md keep the old number.
