| Escalating daily pixel rewards (triangular per-day) | completed | feature | normal | 2026-07-14T22:38:42Z | 2026-07-14T22:46:49Z |
Reward doing more habits in a single day: the Nth habit checked in a day reveals N units of pixels (1+2+3+... = triangular). Derive revealed pixels from the log per-day triangular sum instead of a flat checks counter; recalibrate pixelsPerCheck so a perfect month still finishes an image. Update DESIGN.md, README.md, ARCHITECTURE.md.
Summary of Changes
Escalating daily reward implemented in index.html:
- Reveal is now derived from the log instead of a stored
checkscounter. New helperstriangular(k)andrevealedUnits(image)sumk·(k+1)/2units per day (days ≥ startedAt). The Nth habit checked in a day is worth N units, so a 4-check day = 1+2+3+4 = 10 units. getRevealInfo:revealedCount = min(opaque, floor(units · pixelsPerCheck)).pixelsPerCheckForrecalibrated tomax(1, round(opaque / (triangular(habitCount) · 30)))so a perfect month still fills the image (verified: ~30 days).onHabitToggle: snapshotsbeforeprior to mutating the log; uncheck path no longer touches a counter (past days can't un-reveal). Removed unusedcomputeFloor.- Dropped vestigial
checksfield fromnormalizeImage/buildImageFromDef; legacy saves load fine (field ignored, reveal recomputed). - Upload day-estimate updated to use
triangular(habitCount)·ppcper perfect day. - Docs updated: DESIGN.md §3.2 + §9, data model, README.md, ARCHITECTURE.md.
Validation: no external refs (grep http/https/fetch clean), node --check passes, pure-function simulation confirms 3/6/9/12-px escalation and ~30-day perfect-month finish. Not opened in a live browser (none available in this environment).
Browser Verification (headless Firefox 152)
Drove the real app's DOM in headless Firefox with a seeded 4-habit / 4x4-opaque state (pixelsPerCheck=1). Checking habits 1–4 revealed running totals 1, 3, 6, 10 (deltas +1, +2, +3, +4) — escalating exactly as specified, day total = 10. Unchecking the 4th dropped 10→6 (only today's contribution shrank). No console or window errors (errors: []).
