evidence(OMN-15963): tombstone dead-carrier binding for omninode_infra#885 - #6453
Conversation
…a#885 omninode_infra#885 CLOSED UNMERGED (mergeCommit null, head preserved at a2545fd7) while its OCC autobind companion MERGED bound to it, leaving a merged evidence record vouching for code that never reached dev. Repaired the append-only way: both merged base receipts are preserved byte-for-byte and net-new command.supersede.0001.yaml ordinal records carry the rebound receipts, plus two contract-level retirement entries that resolve the dead-carrier items to status=superseded at runtime. Disclosed divergence from the precedent this follows: #885's commits are NOT members of #884's commit set and its diff did not land in any form. What landed is a different, stronger fix for the same defect class (GATEWAY_V1_PATHS + _resolve_gateway_tenant_from_request, merged at 0fa14c8f) rather than #885's PUBLIC_V1_PATHS exemption. Supersession of the binding is claimed; equivalence of the diffs is not. Append-only proven by measurement: zero contract_entry_sha256 drift across all 10 pre-existing entries. Both checks RED-proven (3 controls / 2 controls).

…lity The first CI pass failed occ-preflight/eligibility and verify/verify with reason=pr_ticket_mismatch: eligibility is evaluated per-PR and requires a PASS receipt bound to this carrier, but every other artifact on this PR binds to omninode_infra#884 (the landed carrier they assert). Adds the contract's established occ-self-bind-pr-N artifact for #6453. Hand-authored by the repair lane rather than the autobind emitter, so it is source=manual unlike the generated sibling self-binds. Asserts BOTH the carrier PR number and its head branch, RED-proven against a wrong branch name and against the already-merged sibling companion (each exit 1). Zero contract_entry_sha256 drift across all 10 pre-existing entries.

Defect
omninode_infra#885is CLOSED, mergedAt null, no merge commit — its head is preserved ata2545fd7but is not an ancestor ofdev(compare API:status=diverged). Its OCC autobind companion nevertheless merged at1c98fab75559fe04a242730c984c475e8840b092, binding a merged evidence record to code that never landed. Two entries on this contract carry that dead binding:dod-OmniNode-ai-omninode_infra-pr-885(Evidence-Source stamp)dod-OmniNode-ai-omninode_infra-pr-885-ci(product-diff-scope stamp)Because both ids match the structured
dod-<org>-<repo>-pr-<n>binding form,node_dod_verifyderives a::pr-live-stateassertion requiring MERGED + green checks. On a closed carrier that can never clear, and the entries are immutable undervalidator_occ_append_only.Mechanism
Two layers, following the merged-path supersede convention established by OCC#5771 for the OCC#5763 dead carrier:
command.supersede.0001.yamlordinal records over each dead-carrier base receipt. Both merged base receipts are preserved byte-for-byte (git diffagainstdevfor those two paths is empty).evidence_artifact: supersedes_dod_evidence:<retired id>, so the retired items resolve tostatus=supersededat runtime. The receipt-level record alone does not reach that surface; the contract-level record alone does not reach the receipt surface.Honest divergence from the precedent
OCC#5771 could assert the dead carrier's head commit was a member of the landing PR's commit set — same content, merged. That does not hold here, and the claim is not copied:
#885's commits (ba04f4e4,a2545fd7) are absent from#884's commit set.#885's distinctive symbolGATEWAY_ATTACH_PATHappears zero times indev'sdocker/onex-api/main.py.#885's diff did not land in any form. What landed is a different and stronger fix for the same defect class:#885proposed exempting the three gateway paths viaPUBLIC_V1_PATHS;#884(merged0fa14c8f) instead added a separateGATEWAY_V1_PATHSset routed through_resolve_gateway_tenant_from_requestinsidem4_usage_metering_middleware, resolving the tenant from the gateway bearer rather than dropping auth. The bootstrap-circularity defect is genuinely closed ondev, by different code. Supersession of the binding is claimed; equivalence of the diffs is not.Falsifiability
Both checks were read back out of the committed contract and executed verbatim.
