ENGINEERING DECISIONS & PROOFS
01
HYPHA
+340% Throughput 0B Net
BLE-only transport → Hybrid BLE + Wi-Fi Direct
INITIAL APPROACH

BLE discovery + BLE payload transfer.

FAILURE MODE

Acceptable for handshakes and tiny messages. Severe 20KB/s bottleneck for media, voice bundles, and larger packets.

DESIGN CHANGE
BLE
└── discovery (advertisement packets)
└── proximity presence
└── Noise XX cryptographic handshake

Wi-Fi Direct
└── opportunistic group owner peer negotiation
└── high-throughput bulk bundle transmission (12+ MB/s)
RESULT

Hybrid asynchronous DTN transport architecture with 0 bytes internet usage.

02
LUMIUM
0 Race Conditions 15s Lease TTL
Last-write-wins synchronization → Transactional ActiveTimerLease
INITIAL APPROACH

Client-side timestamp comparison (Last-Write-Wins).

FAILURE MODE

Clock skew across phone, web, and kiosk clients caused duplicate concurrent focus sessions and ghost sessions.

DESIGN CHANGE
ActiveTimerLease
└── Firestore atomic transaction lease lock
└── 15-second heartbeat renewal pulse
└── Automatic graceful reclaim on client disconnect
RESULT

Guaranteed single-owner focus lock across all distributed platforms without race conditions.

03
UNRAVEL
0% Hallucination Tree-sitter AST
Raw-context code inspection → Deterministic AST evidence
INITIAL APPROACH

Feeding raw repository files directly into LLM prompts.

FAILURE MODE

LLM hallucinated phantom function signatures and missed cross-file call dependencies in large multi-crate repos.

DESIGN CHANGE
Source Code → Tree-sitter Parser → Symbol Table → MCP Tool Server → LLM Verification Layer
RESULT

The AI never becomes source-of-truth; AST structural evidence does.

04
ERUDITE
0% Style Bleed FSRS-4.5 Active
Global card DOM rendering → Isolated Shadow DOM sandbox
INITIAL APPROACH

Direct HTML injection of user-created flashcard templates.

FAILURE MODE

Custom user CSS styles leaked out and broke application navigation, buttons, and responsive grid layout.

DESIGN CHANGE
Shadow DOM Isolation Sandbox + DOMPurify Strict Sanitization Pipeline
RESULT

Total style encapsulation for custom LaTeX, formulas, and rich-text cards.
