# SUNNY M Lab

> SUNNY M Lab is a sensory semantic system. Coffee is currently the primary medium through which this system is expressed, observed, documented, and validated. The research core is not oriented toward achieving a fixed flavor profile — it is oriented toward observing how different heat progressions and roast conditions translate into distinct, repeatable cup structures. These phenomena can be observed, named, and documented. This archive exists to define the terminology, record the phenomena, and build an observational system that can be continuously referenced, compared, extended, and validated.

SUNNY M Lab is the research and semantic layer: phenomena definitions, observational terminology, relational structure, and the archive system. SUNNY M Specialty (https://sunnymspecialty.com) is the sensory access layer where research releases enter the world and observation begins.

## Phenomena Atlas

The core knowledge base. Each entry defines a named, observable roast phenomenon with a formal description, plain-language summary, and research status. All phenomena are documented in English and Traditional Chinese.

- [Phenomena Atlas](https://sunnymlab.com/phenomena/): Full index of documented roast phenomena
- [Alive Cup (AC)](https://sunnymlab.com/phenomena/alive-cup/): Meaningful flavor state transitions within a single cup across its full temperature arc — from first sip to fully cool
- [Hot Cup Memory Point (HCM)](https://sunnymlab.com/phenomena/hot-cup-memory/): The most memorable flavor impression forms at high temperature (above 65°C); the cup settles quieter as it cools without losing structure
- [Observation Progression (OP)](https://sunnymlab.com/phenomena/observation-progression/): The same coffee presents differently at different points in time post-roast; the arc is documentable and batch-specific
- [Cup-Driven Maturity (CDM)](https://sunnymlab.com/phenomena/cup-driven-maturity/): Maturity confirmation is based on cup evaluation rather than roast event markers such as first crack, DTR, or color measurement
- [No Crack Roast (NCR)](https://sunnymlab.com/phenomena/no-crack-roast/): A roasting system in which maturity confirmation does not rely on first crack as an acoustic event or color as a visual endpoint
- [Pre-Crack Maturity (PCM)](https://sunnymlab.com/phenomena/pre-crack-maturity/): The expected cup maturity state is established before first crack occurs as an acoustic event
- [Roast Event Asynchrony (REA)](https://sunnymlab.com/phenomena/roast-event-asynchrony/): Traditional roast event timing and actual cup maturity do not occur in the expected synchrony
- [Terminal Decline Roast (TDR)](https://sunnymlab.com/phenomena/terminal-decline-roast/): A roast profile in which energy application in the final stage follows a deliberate, controlled declining trajectory — producing lower perceived edge, more integrated acidity, and smoother structural transitions
- [Caramelization Divergence (CDV)](https://sunnymlab.com/phenomena/caramelization-divergence/): Differences in energy distribution across caramelization-related reactions create distinct sensory emphases between the hot and cool stages of the cup

## Phenomenon Boundary Archive

Boundary condition documentation. Records the conditions under which a given phenomenon stops holding — and what exists at the edge of each phenomenon's observable range. Failure observations are not exceptions outside the system. They are data that define the boundaries of the system.

- [Phenomenon Boundary Archive](https://sunnymlab.com/failure-archive/): Full index of boundary conditions
- [Energy Gap BT Stall (EGBS)](https://sunnymlab.com/failure-archive/energy-gap-bt-stall/): Bean temperature enters a near-stalled state after a rapid rise or decline — produces dark-chocolate bitterness or charcoal-like near-burnt boundary expression
- [Cliff-Induced Cold Collapse (CICC)](https://sunnymlab.com/failure-archive/cliff-induced-cold-collapse/): A sharp temperature drop disrupts reaction continuity — the hot cup holds, the cool cup collapses structurally. Boundary condition for Alive Cup

## Observer Protocol

Structured methodology for observing and recording cup phenomena across temperature stages and post-roast time windows. Defines temperature stages (Hot Cup above 65°C, Warm Cup 50–64°C, Cool Cup below 49°C), temporal observation windows (Day 1–3, Day 4–14, Day 15+), and observation fields.

- [Observer Protocol](https://sunnymlab.com/observer-protocol/): Full protocol including temperature stages, temporal windows, observation fields, phenomena tags, archive fields, and boundary conditions

## Research Notes

Observations from the roasting room, case studies, and quarterly summaries. Documents the research process, not conclusions. Notes are currently being organized.
