generate_base_drafts hardens every base draft to a transparent PNG with
_harden_transparency. When the provider returned a non-PNG file (webp,
jpg, or gif), the hardened PNG is saved under a new path and the original
draft is left in cache/images. Nothing prunes that directory outside the
gateway housekeeping loop, so a CLI or desktop draft round leaks one
original per non-PNG draft.
Remove the original after a successful hardening when the output path
differs from the input. PNG inputs (including mixed-case suffixes like
.PNG) are hardened in place so a case-insensitive filesystem cannot
treat with_suffix(".png") as a different file and unlink the output.
Each hatch generates one row strip per state into cache/images and
extracts the animation frames from it, but never removes the strip. The
only cleanup for that directory runs in the gateway housekeeping loop,
which a CLI, desktop, or cron hatch never starts, so the strips
accumulate for good.
Drop the strip after every attempt once its frames are decoded into
memory, including failed or retried attempts, so a hatch no longer grows
the image cache without bound.
OpenRouter/Nous image gen now runs a quality-first model chain by default:
attempt the highest-fidelity OpenAI image model first, then fall back to
Gemini 3 Pro Image when it's access-gated/unavailable/times out. An explicit
OPENROUTER_IMAGE_MODEL / config model override pins one model with no fallback.
Atlas validation rejects malformed model output instead of shipping it: adds a
per-state collapse guard (a single sliver/fragment row no longer passes because
other rows are healthy), on top of the existing postage-stamp + multi-pose
checks.
Desktop: pet-gen native notifications are now "global" (not tied to a chat
session), so a background generation started from the command center fires an
OS notification when the user is away even with no active session. Adds a
neutral "This can take up to 5 minutes." banner on step 1, and lets the
provider picker auto-size.
Tests updated/added for the OpenRouter fallback chain, the collapse guard, and
the global notification path.
Remove cute/chibi-biased wording from base draft variations and explicitly preserve the requested mood across base and row prompts so scary, eerie, or other non-cute concepts are honored while keeping sprite constraints.
Ship the final pet-generation UX polish (provider picker behavior, step-2 cancel flow, banner integration, and visual consistency) and make saturated-chroma background removal C-op driven so hatch processing no longer hammers the machine during long runs.
Turn a text prompt into a petdex-spec spritesheet (8×9 grid of 192×208
cells), grounded so every animation row stays the same creature:
- orchestrate: base drafts (distinct variation nudges) → per-row grounded
generation → atlas compose; one image call per row, rows fan out in parallel.
- atlas: frame-perfect registration in normalize_cells — 1-D cross-correlation
of each frame's column-mass profile locks the body (robust to limbs/cape),
one shared per-state scale, bottom-anchored; plus alpha-hole repair, gutter
severing, and interior-seeded chroma-pocket clearing.
- prompts: pixel-art-by-default style hints + registration constraints.
- store: local pet write (register_local_pet), slugify/unique_slug,
export_pet, slug-realigning rename_pet, createdBy provenance.
