0.1.0-alpha - 2026-11-13

Added

• Sticker: a sticker of the catalogue with a reference to its image — never a javascript:, vbscript:, data: or file: one —, a required text alternative of 1 to 250 characters, an optional licence and attribution, and its retirement.
• Stickers: stickers granted once and revoked with their placements; placed on the surfaces the policy lets each holder use, when owned, not retired and within the site's limits; moved and removed by their holder only; hidden for a reason and restored by moderation; shown to a viewer, in placing order, unless the viewer turned them off; the erasure of a holder and of a surface.
• Transform and Limits: positions in thousandths of the sticker layer, scales of 10 to 400 percent and rotations of -180 to 180 degrees, narrowed by the site, which also limits the stickers of a surface (12 by default, 100 at most) and of a holder (500 by default, 10 000 at most).
• PlacementRequest: a request read from a form or from JSON of at most 4 KiB, every fault an InvalidSticker.
• Placement: a placement with an identifier from a secure source and its moment in UTC.
• Contract\SurfacePolicy, Contract\PlacementModerator and Verdict: whose surfaces, with no permissive default, and a new placement hidden at once for a reason.
• ViewerPreferences and PlacementView: a viewer who turns stickers off, and each placement shown with the sticker's text alternative and credit.
• StickerSheets: sticker sheets and albums as sets of tilttek/sets, with their tiers and rewards, completed once from the stickers a holder owns.
• Event\StickerGranted, Event\StickerRevoked, Event\StickerPlaced, Event\PlacementHidden, Event\PlacementRestored and Event\PlacementRemoved, identifiers only.
• Holders and surfaces referenced by a stable identifier, never by an e-mail address.
• Contract\StickerCatalog, Contract\OwnershipStore, Contract\PlacementStore and their adapters in memory, with Policy\InMemorySurfacePolicy.
• The fuzz target of a placement request and the benchmarks of a full surface.
• The documentation in doc/, one file per topic, indexed by the README.
• CONTRIBUTING.md, SECURITY.md and CODE_OF_CONDUCT.md.
