Summary

Hand-authored OCC companion for OmniNode-ai/omnimarket#2937 (OMN-19550). occ-preflight/eligibility declined that PR terminally at head 7826cc6baf65117804ec013ee80a7e4f66ea6a10 with skip:NO_RED_DERIVABLE_CHECK (job 108367006588, run 36228505155): the diff is a db_io.db_tables ownership declaration in scripts/application-relation-ownership.yaml plus its regenerated evidence json and a test-count assertion, none of which is a code path the producer can derive a RED from. Per OMN-15247 the remedy is hand-authored evidence.

No other companion exists for PR #2937 (search of this repository's open and closed pull requests for "2937" returned 0). OMN-19550 already carries two companions, each bound to a different sibling PR: #11418 (merged, for omnibase_infra#4154) and #11275 (open, for omnimarket#2905). Neither cites #2937.

What this adds

Appends two dod_evidence entries to the existing contracts/OMN-19550.yaml and their receipts:

• dod-OmniNode-ai-omnimarket-pr-2937: content-bound probe pinned to the PR head. scripts/application-relation-ownership.yaml's new role: session_content field line is present at 7826cc6baf65117804ec013ee80a7e4f66ea6a10 (grep count 1, exit 0) and absent at the merge base cd220fd03a25d0e1c578e98ad3e80f385cf587b7 (count 0, exit 1). Positive control on the merge-base ref (a known pre-existing role) confirms the read returns real content rather than failing closed.
• dod-OmniNode-ai-omnimarket-pr-2937-scope: product diff scope. The PR's file list carries exactly 3 files and 0 migration SQL files, confirming its own declaration-only claim.

Neither entry binds any of OMN-19550's six acceptance criteria: PR #2937 is step 1 of the forced three-part order (declare ownership, vendor the migration in omnibase_infra#4154, land the node package and migration in omnimarket#2905) and proves none of AC1-AC6 itself.

Purely additive: every existing OMN-19550 entry and receipt is byte-identical. Verified by recomputing contract_entry_sha256 for the three pre-existing entries (dod-OmniNode-ai-omnibase_infra-pr-4154, dod-occ-diff-derived-behavior-proof, occ-self-bind-pr-11418) with the real compute_contract_entry_sha256 function and reproducing each recorded value byte for byte.

Verification

• check_contract_change_rebinds_receipts.py --staged, check_receipt_hardening.py --staged, check_contract_substance_floor.py and check_contract_dod_authoring.py all pass locally on the changed files.
• Full pre-commit run over the touched files passes.
• Behavior proof for the product PR: independently re-ran uv run pytest tests/unit/scripts/test_application_relation_inventory.py -q in a fresh worktree at the PR head (clean, HEAD=7826cc6baf65117804ec013ee80a7e4f66ea6a10) -- 12 passed.
