Publish reconciled docs from the pinned Marketing source
Publish the reconciled Marketing documentation as a pinned Mintlify source copy, including all 15 restored Recoup-branded research references. Authoring lives in Marketing content/docs/source; host branding/settings remain local to Docs.
SOURCE-PROVENANCE.json pins actual Marketing merge 4897009f2007af8ecac0d70535ed53950d1010d3 and hashes all 231 copied files. Checks compare navigation, inventory and contents; regression tests reject modified/unlisted MDX and OpenAPI files.
Validation: provenance and publication guards pass; Marketing's 427 tests, seven docs checks, contract checks and remote production build passed. Marketing production is READY and canonical research HTML/Markdown/LLM readbacks return 200.
This PR is merged at d688d2dd06caebea7bbc91be761311d903a24de0. Mintlify deployment repair is explicitly deferred by Sidney: docs.recoupable.dev still serves old content, restored research pages return 404 and the human /mcp path returns 405. This source merge does not establish Mintlify publication. Host cutover/DNS/archive remain separate.
Coordinates epic #318, packages 1–7, especially #337 and #325.
Final production readback: API is READY at 925a57a704c7a9e32ee817e040b47a99ca144dd1 and Marketing at 8b36ab7677e3bd34c33e39f499518a301a2230c9. Each is one unrelated commit ahead of the reconciliation release; comparisons show no reconciled route or docs-source changes. The recorded release/provenance commits remain unchanged.
