Situational Framework
Captured Context.Suggested Moves.Currently developing and field-testing Field Notes, a system that captures real-world travel signals and turns them into reusable decision playbooks, powering both a standalone product and the broader HADE ecosystem.
An Adaptive System, Enhanced in Real Time
Field Notes combines structured guidance, live data, and adaptive intelligence to support decisions on the ground.
Context Layer
Field Notes
An offline-first city intelligence layer — structured knowledge, cached live data, and local expertise always available on the ground.
Composed of
Intelligence Layer
HADE
Spontaneity Engine
A real-time adaptive engine that ingests Field Notes context, interprets current conditions, and returns spontaneous, confidence-calibrated moves.
Returns
The Feedback Loop
HADE outputs are injected back into Field Notes — or surface directly in the interface — creating a continuous context → intelligence → suggestion cycle that improves with every trip.
The Editorial HandshakeI am engineering an automated pipeline that synthesizes industry travel reports, my 10+ years of global travel experience, and real time telemetry into adaptive situational playbooks.
In this current phase, HADE uses agentic logic to generate playbooks from high integrity data APIs and environmental signals. While the core engine is powered by AI synthesis, the roadmap is focused on a hybrid intelligence model where these digital strategies are eventually calibrated and verified by direct human expertise.

“Chiado's hills become slick and cafes overflow during sudden rain. Local movement shifts to the covered 18th-century arcades and gallery corridors.”
Synthesis (Agentic Logic)
Predictive Validity:Checks L1 telemetry to confirm rain will persist for 60+ minutes.
Trust Calibration:Detects signal freshness—verified local checked in 45m ago.
Heuristic Filter:Rejects 'Nearby Cafe' due to high-occupancy probability.
It's crowded there.

Not the move?
The Community SignalThe "Editorial Handshake" helps HADE turn traveler insights into polished situational moves that keep the knowledge base growing in real time.
Signal Ingestion
Raw user intent captured via geofenced triggers and biometric validation.
Agentic Refinement
AI synthesizes the "Move" to match the authoritative Field Note framework.
Input: Raw Traveler Note
"The back room at Cafe A Brasileira is always empty during rain. Good wifi."
Output: Synthesized Note
"When the rain hits Chiado, bypass the storefronts. The rear gallery at A Brasileira offers a quiet retreat for deep work."
Trust is an engineering constraint, not a feature.Every rule in the integrity layer exists because a specific failure mode was identified. These constraints shaped the architecture — they were not added afterward.
Notes degrade after 3 hours
Field Notes contribute to synthesis only within a 3-hour credibility window. Notes older than 24 hours are archived and excluded unless re-verified by a second contributor in the same zone.
Tradeoff: Reduced recall volume in slow-update areas. Accepted to prevent stale data from triggering confident recommendations.
≥20 min gap between surfaces
The Dopamine Governor enforces a minimum 20-minute cooldown between suggestions surfaced to any individual session. A suggestion surfaced too frequently becomes noise — and noise erodes trust faster than silence.
Tradeoff: Missed opportunity windows in fast-changing environments. Accepted to protect long-term engagement integrity.
No raw coordinates transmitted
Location is resolved to a named zone (e.g. 'Chiado') on-device before any server communication. Raw GPS coordinates are never stored or transmitted. This was a founding architectural constraint, not a retroactive privacy patch.
Tradeoff: Zone-level precision reduces hyper-local accuracy. Accepted as a non-negotiable privacy boundary.
500m radius check-in required
Check-ins must be recorded within 500m of the referenced location to count toward a Field Note's credibility score. Notes submitted outside this radius enter a 48-hour cross-verification queue and cannot trigger synthesis until resolved.
Tradeoff: Increased contributor friction at the point of submission. Accepted to ensure the knowledge base reflects direct, firsthand observation.
Design Rationale
Each constraint above represents a deliberate tradeoff. The system does less in certain conditions to do one thing reliably: surface suggestions a traveler can act on without second-guessing the source.
The Framework
Travelers think in situations, not lists.
Arriving late in a new city
Hungry but overwhelmed
Rainy exploration day
Only two hours to explore
Need a quiet place to work
Tourist areas overcrowded
Jet lag early morning
Phone battery dying
The Field Notes
Real-world example moments
Situation
Jet lag early morning
Problem
Wide awake at 5:30am with limited transit and few open places.
Local Insight
Bakery districts open early and offer quiet seating before rush hour.
Suggested Moves
Walk to a nearby bakery cluster, grab a window seat, and map the morning.
Why This Works
You reset your rhythm while easing into the city before it fills up.
Situation
Hungry but overwhelmed
Problem
Too many ratings and lists, no clarity on what fits the moment.
Local Insight
Local markets narrow choice and signal what is actually fresh now.
Suggested Moves
Head to a market hall, pick one stall with a line, and commit.
Why This Works
The environment filters options so you can act quickly and confidently.
Situation
Rainy exploration day
Problem
Plans collapse when the weather flips and streets are slick.
Local Insight
Covered galleries and arcades create dry walkable loops.
Suggested Moves
Move between indoor arcades, museums, and cafe corridors.
Why This Works
You stay in motion while keeping energy and curiosity intact.
