…63) When a subscriber's monthly plan allocation is exhausted and they also have no credit pack balance, the gateway now returns reason=quota_exhausted with quota_resets_at (ISO 8601) instead of the generic insufficient_credits error — telling them when quota resets rather than directing them to buy credits as their only option. Credit-only users (free tier, unsubscribed) still get insufficient_credits. Consumes the reason + quota_resets_at fields added in edge-auth#153. Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
Error message now reads: "Monthly image quota exhausted. Top off at https://stackbilder.com/img-forge#credits or wait for reset on July 1, 2026." Previous version omitted the URL (leaving users with no actionable next step in terminals that only show the message string) and the year (ambiguous for December users). Also applied same "Top off at <url>" phrasing to insufficient_credits. Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
Error now reads: "Monthly image quota exhausted (N images/mo). Add credits from $9.99 at https://stackbilder.com/img-forge#credits — or wait for reset on [date]." quota_limit threads from edge-auth QuotaResult → QuotaCheckResult → message. Price anchor ($9.99) is the smallest credit pack entry point — gives users a cost signal before they navigate to the purchase page. Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
… img2img params image_list_models: description no longer hardcodes "13 models / 11 CF models" — live model count comes from img-forge; gateway description was stale after #61. image_generate: adds input_image, mask_image, input_strength, strength to inputSchema so RunwayML img2img/inpainting cf_model values are actually callable. cf_model description now calls out that RunwayML variants require input_image.

TIER_ALLOWED_QUALITY had Gemini blocked with a "re-add when capacity confirmed" comment. Capacity is confirmed; tool descriptions already promise ultra_plus to Pro plan users. Aligns code with contract. Fixes failing test: allows pro-tier user who passes model=gemini-3-pro-image-preview Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
