Dual-content phase 1: app code, tests, API layer, and UI components expanded via Codex
A Codex agent session on the threads-automation project produced a large-scale expansion across four product areas: application code, test coverage, the API layer, and UI components. The session ran for approximately 64 minutes and touched 57 files in aggregate, adding 10 581 lines and removing 91. The agent completed 126 tool calls across 6 turns using model gpt-5.6-sol, indicating a methodical, multi-step implementation rather than a single bulk write. The branch at the time of collection was codex/dual-content-phase1, consistent with a planned phase-1 milestone. Collection quality was rated high from a single agent-session source, and a privacy scan found no sensitive findings. Raw transcripts, diffs, local file paths, and source text remain local and are not included in this public record.
