This changelog file

Loaded the bundled Codex Python/Pillow runtime and ran Hatch Pet validate_atlas.py --require-v2 --chroma-key '#0000FF' for all four canonical atlases.
Synchronized fleet check-ins and verified each destination's live ComputerName plus pinned ED25519 SSH host-key fingerprint.
Staged only pet.json and spritesheet.webp, verified exact SHA-256 values and v2 manifest fields, preserved divergent destinations, and installed atomically per pet.
Used jq, shasum -a 256, sips, stat, and the installed ChatGPT app.asar to verify manifest semantics, atlas dimensions, private permissions, and custom-pet discovery support.
Re-ran a read-only idempotency comparison across all 24 host/pet pairs; every result was would-skip.

Source validation: 4/4 WebP RGBA atlases, 1536 x 2288, 8 x 11, sprite version 2, no errors or warnings, zero transparent hidden-RGB residue.
Final fleet state: all six hosts report display names Joey,TARS,CASE,KIPP and exact source hashes.
Permissions: pet directories 0700; pet.json and spritesheet.webp 0600.
App contract: /Applications/ChatGPT.app, bundle com.openai.codex, contains the dynamic custom-pet discovery path on both fleet app builds.
No ChatGPT/Codex process was interrupted or restarted.

No rdmsm4x pet content required replacement; no rdmsm4x content backup was created.
Fleet rollback root: /Users/richh/.codex/pet-backups/codex-pets-fleet-20260828T203058EDT/ on hosts where divergent packages existed.
Detailed backup inventory and undo instructions: /Users/richh/dev/LLM/codex/codex-pets/reports/fleet-deployment-20260828/README.md.
Undo requires safely checkpointing active ChatGPT/Codex work, moving the current package aside, and restoring the matching retained directory on the affected host.

None. Opening the pet picker causes the app to rescan the pet directory; no restart is required.
