Batch 48 / Cycle 1 (greenfield Step 7). Closes cumulative review batches 31-33 F2 and 28-30 F3 by replacing the duplicated private _iso_ts_now() one-liners with a single Layer-1 helper: src/gps_denied_onboard/helpers/iso_timestamps.py iso_ts_now() -> str Output format matches the canonical FDR _TS fixture (YYYY-MM-DDTHH:MM:SS.ffffffZ); no FDR schema change. Migrated call-sites (3): c7_inference/onnx_trt_ep_runtime, c7_inference/thermal_publisher, plus the 3 c6_tile_cache callers that previously imported from the local c6_tile_cache/_timestamp shim (now deleted, superseded by the Layer-1 helper). Spec drift resolved (Choose A, user-approved): spec listed 5 call sites + +00:00 regex; on-disk reality at batch start is 3 sites + Z-suffix matching every existing helper and the FDR _TS fixture. Spec preamble + AC-2 regex updated in the task file; documented in batch_48_cycle1_report.md. Tests: 9 new AC tests (AC-1..AC-7 + Layer-1 invariant + public-surface defensive); 216 focused tests pass including the unmodified AZ-272 FDR schema suite and AZ-270 / AZ-507 layering lints. Verdict: PASS (no findings). Co-authored-by: Cursor <cursoragent@cursor.com>
