Signal Outcome

Mark a pattern as successful (+) or problematic (-). Signals influence future ranking.

Protocol

1. Parse $ARGUMENTS:

   • First arg: + or -
   • Second arg: pattern name (e.g., #pattern/session-token-flow)

2. Add signal:

source ~/.config/ftl/paths.sh 2>/dev/null; python3 "$LATTICE_LIB/context_graph.py" signal "$SIGN" "$PATTERN"

3. Confirm result.

Usage

/lattice:signal + #pattern/session-token-flow    # Pattern worked well
/lattice:signal - #constraint/max-batch-size     # Constraint caused issues

Output Format

Signal added: #pattern/session-token-flow -> net +2

Storage

Signals stored in .lattice/signals.json:

{
  "#pattern/session-token-flow": {
    "signals": ["+", "+"],
    "net": 2,
    "last": 1704153600
  }
}

Effect on Ranking

signal_factor = 1 + (net_signals * 0.2)

• net +5 = 2.0x weight
• net -5 = 0x weight (effectively hidden)

Constraints

• Only writes to .lattice/signals.json
• Does not modify workspace files
