Record current trading acceptance and NativeStack2604 host ruling - #847

Scope

The runtime documentation still requests acceptance for lock 1fb9f8ca and describes NativeStack2604 as holding no trading data. This PR records the completed 5a acceptance, replaces that stale host restriction with the dated command-center ruling, and publishes the retained 5b result as a sanitized pipeline receipt.

• Custody: readiness-runner prepares this record PR under CC070938Z ruling 3; 5f lands it only on a command-center cue.

The final integrated validation passed after the supported publication registration was refreshed. Read-only receipt verification matched all 39 original 5b artifact anchors and six vendor source anchors; the independent completeness read found no material missing condition. Runtime acceptance, data acquisition, simulation and installation were not repeated for this PR.

Decision record

blueprints/us-equities/runtime-2604/receipts/acceptance-20261008.json and blueprints/us-equities/runtime-2604/receipts/backtest-pipeline-20261008.json preserve the executed source hashes, both acceptance attempts, redaction scope and qualification limits. The current host ruling supersedes the older placement statement while dated historical searches keep their original scope. A future engine move remains gated by the first release containing NautilusTrader PR #5041; rc6 stays draft.

5b is pipeline evidence: Layer 1.5 CIK identity, split reconciliation and terminal-price resolution remain unaccepted. Its executed provider-midnight-plus-24h convention is retained; XNYS-close correction belongs to the entrance exam. The records confer no strategy eligibility or broker-order acceptance.

Host evidence

This PR adds sanitized derivatives under the trading blueprint and changes no evidence/hosts/ receipt or platform status.
