The Two-Loop Law

Nindova may be satisfying during the current Session. It may be inviting when a person returns another night. It must never use satisfaction to make the current Session harder to leave.

Anything that makes tonight harder to leave is a bug.

Non-negotiable behavior

• One Rasoi Pairs rule and two equal tonight-only board profiles; no game menu, rounds, progression levels, unlocks, or escalating difficulty.
• A production Session closes itself within fifteen minutes.
• No score, visible count, timer, countdown, streak, grade, achievement, collection, missed-night state, sleep score, or randomized reward.
• The board is authored and deterministic. Every reachable nonterminal state exposes a legal pair, and every legal choice preserves solvability.
• Help identifies a safe pair but does not remove it.
• Audio, animation, precision movement, and sight are optional; native controls and visible text names carry the rule.
• State stays local. There is no account, analytics, advertising, app telemetry, app-controlled remote logging, or third-party runtime request. Static-host operational logs are outside the app boundary.
• Same-night voluntary return is quiet and idempotent, and starts from intake rather than a promoted replay button. Reselecting the same profile yields its identical deterministic board.
• “Not now” never prevents a voluntary return later that night.
• “Same time tomorrow?” stores a local intention, sends no notification, and creates no urgency.
• Match feedback is deterministic and bounded; no flash, screen shake, particle shower, combo, or randomized effect may turn it into a reward schedule.
• Gentle and Deeper alter authored occlusion only. They never create a stored result, ability label, history, rank, payout, longer deadline, or different ending.
• “Dim and rest” remains the primary completion action. Optional Rasoi Image Drift collects no response and contains no route back to play.

Immutable language

The intake promise is: “Nothing to win. Nothing tracked. Nothing you can do wrong.”

The end card begins: “The session is over. That’s the point.”

Nindova is a behavioral design study for people aged 13 and up. It is not a sleep tracker, sleep-performance tool, memory intervention, or treatment. Masala Mound has not been clinically shown to make people sleepy, improve sleep, improve general memory, or create a useful dopamine response at any age. Persistent sleep difficulty deserves evidence-based care such as CBT-I with a qualified clinician.

Cultural direction

The motifs are everyday forms: belan, chakla, tawa, chimta, steel katori, tiffin, masala dabba, chai glass, and pressure cooker. Indigo, madder, marigold, brass, wood, and restrained phulkari-inspired geometry shape the surface.

Sacred symbols, flags, festival collage, and generic “exotic” styling are excluded. The direction is Punjabi-inspired; completed human cultural-authenticity review is not claimed.
