Add reviewed physical-reference relationship layer
Adds a reviewed record_id-keyed relationship layer for 309 Standard records: 52 confirmed endpoint photographs, 1 longitudinal continuation, 232 owner-confirmed record references without a separate exact-endpoint assertion, and 24 two-sided references. Reference photographs and internal review ledgers are not bundled. metadata.csv and canonical videos are unchanged. Documentation also records the Framelapse/InShot authority boundary, corrects AE/WB/autofocus/stabilization to a majority-level retrospective statement, and keeps the 4K/30-fps profile explicitly candidate-only. Source metadata revision: ba7e7903901767f2d5a4367d7ae22c2546366d6d. Local public-staging validation: 24/24 checks passed.
Publishing the verified draft so it can be merged.
Merged after exact remote-revision verification: seven intended files matched the validated staging hashes, 24/24 public-layer checks passed, no conflicts were present, and canonical media plus metadata.csv remained unchanged.
