The #535 QR lane launched on monster-labs/control_v1p_sdxl_qrcode_monster (SDXL, v1 — the only SDXL release). First real-world results are visibly below monster-labs' showcase gallery, which is generated by their SD 1.5 Monster v2 — the widely-acknowledged best art/code blender; the SDXL port trades that blending for base-render sharpness. No newer release (no SDXL v2, no FLUX) exists.

Plan:

artpipe: add a variant param to qr_monster — classic (SD 1.5 base + control_v1p_sd15_qrcode_monster v2 subfolder, 512/768px, new default) and sdxl (existing stack, 768/1024px). One variant resident at a time with VRAM eviction on switch (9500 MB lease covers either stack, not both). Per-variant tuned defaults: classic scale 1.1 / 36 steps, sdxl scale 1.35 / 32 steps; guidance 7 both. Size requests snap to the variant's native range.
backend/angular: plumb variant through GenerateQrArtCommand + the QR tool UI; temporarily raise the QR endpoint rate limit to 60/hr (1/min) for the tuning/testing window (was 6/hr).
infra/CI: env-image rebuild (SD1.5 base fp16 + v2 ControlNet ≈ +3.5 GB), redeploy, then an on-hardware tuning pass (scannability vs aesthetics) before locking defaults.
Watch: root repo of the SD15 ControlNet is the WEAKER v1 — weight patterns must pin v2/* (regression-guarded in tests).

Implementation up:

spikersoft-artpipe PR #45 — MERGED: variant registry (classic = SD1.5 + Monster v2 subfolder, new default; sdxl = existing), single-resident pipeline with VRAM eviction, per-variant tuned starting defaults (classic 1.1/36@768, sdxl 1.35/32@1024), v2/-pattern regression guard. qrmonster-only env rebuild dispatched (run 18936).
spikersoft-backend PR #504 — variant plumb end-to-end + QR rate limit 6/hr → 60/hr for this testing window + qrmonster into processor DEFAULT_IMAGES/deploy loop. CI running.
spikersoft-angular PR #599 — Classic|SDXL toggle in the AI style form (default Classic). CI running.

Remaining: env+worker image rebuild → redeploy → on-hardware tuning pass before locking defaults. — Opus 5 Agent

Restore QR-art rate limit to 6/hr after the #889 testing window #890

Shipped, deployed, and verified end-to-end 2026-07-28 ~21:00Z.

artpipe #45 + #46 merged: classic (SD1.5 Monster v2) variant as default, scan-pyramid verification, tuned defaults. On-hardware tuning results: classic ≤1.3 never decodes; ≥1.5 decodes 100% of the seed-fixed grid — but only at 512px downscale, never at the raw 768px render (the artistic texture reads as noise to zxing until the module pyramid collapses, i.e. exactly how phones scan these). Hence: default scale 1.5 + a downscale/grayscale decode pyramid in the verifier (also benefits sdxl).
backend #504 + angular #599 merged & deployed: variant plumb, Classic|SDXL toggle live on the tools page, rate limit 60/hr for testing (restore tracked in #890).
Final verification on the deployed worker image (digest e1b75e74), pure defaults: scannable=true, attempts=1, scale_used=1.5, gallery-quality output.

Closing. — Opus 5 Agent
